FIELD OF THE INVENTION [0001] The present invention is related to the use of nonionic hydrophobically modified polysaccharides in personal care and household care compositions; and more specifically, it relates to the use in such compositions of hydrophobically-modified cellulose ethers, such as hydrophobically-modified hydroxyethylcellulose (HMHEC) polymers that show pronounced syneresis in aqueous solutions or in the presence of surfactants, including nonionic surfactants and anionic surfactants such as lauryl sulfate (LS) and lauryl ether sulfate (LES) surfactants. BACKGROUND [0002] In the prior art, the commonly used approach to deliver a polymer coating from personal care or household compositions is through the use of complex formation between a cationic polymer and an anionic surfactant. It is well-known that the mechanism of conditioning for polymers with cationic functionality in hair care, cleansing skin care, and fabric care applications is based on dilution deposition of a cationic polymer-anionic surfactant complex that has both cationic polymer and oppositely charged surfactant.(US5,422,280) As the result of this mechanism, commercial products such as cationic guars, cationic hydroxyethylcellulose, and synthetic cationic polymers show high efficacy in conditioning shampoos, skin care cleansing formulations, and fabric cleansing/conditioning formulations. [0003] In personal care applications, such as in hair care and skin care, and in household care applications, such as fabric care applications, there is a desire to deposit a coating onto the substrate, that reduces the energy needed to move a comb through hair in the wet or dry state or delivers a silky, soft feel to skin or to fabric. This coating can 'also act to improve the luster and moisture retention of hair and skin, as well as their manageability and feel. [0004] The discovery of the improved deposition of silicone resins from cleansing formulations such as shampoos, using cationic polymer-anionic surfactant complexes has lead to the development of this approach to deliver hair conditioning, skin, and fabric conditioning. However, the tendency for silicone buildup on the hair after repeated washing with silicone shampoos, and the desire for clear conditioning formulations has left a strong market need for alternative approaches to achieve silicone-like conditioning on hair, skin, and fabric substrates with or without silicone resins, and without cationic polymers. [0005] Hence, there is also a need in personal care applications for improved overall conditioning performance combined with other desirable attributes such as improved hair volume, manageability, hair repair, or color retention, skin moisturization and moisture retention, fragrance retention, sunscreen longevity on hair, skin, and fabrics, flavor enhancement and antimicrobial performance in oral care applications, and in household applications there is a need for fabric abrasion resistance and colorfastness. [0006] Prior to the present invention, water soluble polysaccharides have been used in personal care applications, such as cleansing and cosmetic skincare, hair care, and oral care applications and in household applications such as cleaning, sanitizing, polishing, toilet preparations, and pesticide preparations; applications such as air deodorants/fresheners, rug and upholstery shampoos, insect repellent lotions, all purpose kitchen cleaner and disinfectants, toilet bowl cleaners, fabric softener-detergent combinations, fabric softeners, fabric sizing agents, dishwashing detergents, vehicle cleaners and shampoos. Widely used commercially available polysaccharides include water soluble polysaccharide ethers such as methyl cellulose (MC), hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), ethylhydroxyethylcellulose (EHEC), hydroxypropyl (HP) guar, hydroxyethyl guar, guar, starch, and other nonionic starch and guar derivatives. [0007] US Patent numbers 5,106,609, 5,104,646, 6,905,694, and 5,100,658 are examples of patents that disclose the use of hydrophobically modified cellulose ethers in cosmetic products. These patents disclose the use of high molecular weight (i.e., 300,000 to 700,000) and aIkyl carbon substitution in the hydrophobe (i.e., 3 to 24 carbons) for use in cosmetic compositions. US Patent No. 4,243,802 discloses a hydrophobically modified nonionic, water-insoluble, surfactant-soluble cellulose ether composition. The use of this material to increase the viscosity of an acidic shampoo composition and to emulsify oil in water emulsions is mentioned. Also, US Patent numbers 4,228,277 and 4,352,916 describe hydrophobically modified cellulose ether derivatives, modified with long chain alkyl group substitution in the hydrophobe. US Patent No. 5,512,091 discloses hydrogel compositions containing water-insoluble hydrophobically-modified cellulose ethers. Publication US2001/0043912 discloses anti-frizz hair care compositions containing a hydrophobically-modified cellulose ether thickener. US Patent number 4,845,207 discloses a hydrophobically modified nonionic, water-soluble cellulose ether and US Patent 4,939,192 discloses the use of such ether in building compositions. US Patent No. 4,960,876 discloses hydrophobically-modified galactomannan compositions as thickeners for use in paint, paper, and ceramic applications. US Patent No. 4,870,167 discloses hydrophobically-modified nonionic polygalactomannan ethers prepared from long-chain aliphatic epoxides, and suggests their possible use in cosmetics, including hand lotions, shampoos, hair treatment compounds, toothpastes, and gels for cleaning teeth. US Patent No. 6,387,855 discloses aqueous compositions containing silicone, a surfactant, and a hydrophobic galactomannan gum for washing and conditioning keratin. [0008] The performance of water-soluble and water-insoluble hydrophobically-modified celluloses has been found lacking in terms of their ability to confer significant and predictable conditioning to keratin substrates. Hence, a need still exists in the industry to have cellulose ethers that confer significant and predictable conditioning to keratin substrates, and deposit films onto solid substrates such as fabrics, when delivered from aqueous compositions. SUMMARY OF THE INVENTION [0009] The present invention is directed to a conditioning composition comprising: (a) an aqueous based functional system selected from the group consisting of personal care products and household care products and (b) a nonionic hydrophobically modified cellulose ether (HMCE) having a weight average molecular weight (Mw) with a lower limit of 400,000 and an upper limit of 2,000,000 and a hydrophobic substitution lower limit of 0.6 wt % and an upper limit amount which renders said cellulose ether soluble in a 5 wt % solution of surfactant and less than 0.05% by weight soluble in water or in a 1wt% surfactant solution and wherein the cellulose ether provides conditioning benefit to a functional system substrate, and (c) at least one active functional system active ingredient. [00010] The present invention is also directed to a process of conditioning an aqueous based functional system selected from the group consisting of personal care and household care products comprising adding and mixing a sufficient amount of a hydrophobically modified cellulose ether that is compatible with the aqueous based functional system to thicken the functional system wherein the hydrophobically modified cellulose ether is a nonionic hydrophobically modified cellulose ether (HMCE) having a weight average molecular weight (Mw) with a lower limit of 400,000 and an upper limit of 2,000,000 and a hydrophobic substitution lower limit of 0.6 wt % and an upper limit amount which renders said cellulose ether soluble in a 5 wt % solution of surfactant and less than 0.05% by weight soluble in water or in a 1wt% surfactant solution and wherein the cellulose ether provides conditioning benefit to a functional system substrate, and the resulting functional system has comparable or better conditioning properties as compared to when using similar thickening agents outside the scope of the present composition. a. The hydrophobically modified polysaccharide polymers of the present invention can be either water-soluble with the formation of a homogeneous gel above a certain (critical) polymer concentration in water or partially soluble in water, (reaching a solution) dissolving with the help of anionic surfactant. In both cases the critical requirement to this polymer is syneresis upon dilution below a certain critical polymer concentration. Such polymers are useful as conditioning agents in 2-in-1 shampoos, in body cleansing formulations, in oral care cleansing systems such as dentifrices, and in fabric cleansing-conditioning systems due to their unique mechanism of activity and dilution-deposition.upon rinsing. b. By syneresis and dilution-deposition is meant that the hydrophobically modified polysaccharide whose original concentration is between 0.05 % -10 % by weight, undergoes liquid-gel phase separation (syneresis) in aqueous solutions when diluted to a final concentration with a lower limit of 0.01 % by weight in solution. The discussed polymers are water-soluble with the formation of a homogeneous gel above a certain (critical) concentration in water of 0.1 %-1 %. The critical and unique requirement of these gels is syneresis upon dilution below certain critical concentration in the personal care composition. These polymers can be synthesized by methods known in the prior art. c. In addition to polymer, the aqueous solution can include surfactant/water mixtures, cyclodextrin/surfactant/water mixtures, water-miscible solvents, salts, water soluble nonionic, cationic, or anionic polymers, and a combination of any of these. DETAILED DESCRIPTION OF THE INVENTION [00011] It has been found that if a hydrophobically-modified polysaccharide polymer undergoes syneresis upon dilution in aqueous solution, the hydrophobically-modified polysaccharide polymer can deposit with high efficacy on substrates such as hair, skin, teeth, oral mucosa, or textile fabrics and can impart great conditioning benefits to the substrates. Upon deposition onto the substrate, the hydrophobically modified polysaccharide can also deposit other ingredients, which improve the condition or enhance the characteristics of the substrate. These polymers also have potential for conditioning skin from cleansing formulations or moisturizing formulations, since these polymers may also better deliver the oil phase typically used in creams and lotions. [00012] Surprisingly, it has been found that nonionic hydrophobically modified polysaccharides, preferably cellulose derivatives and more specifically hydrophobically-modified hydroxyethylceNulose, HMHEC, that show pronounced syneresis in aqueous.solution upon dilution can deposit with high efficacy on hair/skin and can impart great conditioning benefits to keratin substrates. Such polymers impart other benefits in hair styling, body lotions and sunscreens due to hydrophobic film formation on keratin substrates that would act as barrier between the surfaces and the surrounding atmosphere. [00013] These polymers may also be useful as film-formers and co-deposition agents onto the surfaces of hair, skin, and textiles, aiding in protection of the hair, skin, and textile substrates from moisture-loss, aiding deposition of sunscreens and subsequent protection of these substrates from UV radiation, enhancing deposition of fragrance or flavor onto substrates and entrapping fragrance and flavor leading to their improved longevity on these substrates, or aiding deposition of antimicrobial reagents and other active personal care ingredients, resulting in improved longevity of the active on the substrate. In addition, these polymers find use in oral care applications such as dentifrices and denture adhesives to deliver prolonged flavor retention and flavor release. Prolonged release of antimicrobial and biocide agents from these polymers may also find usefulness in household and personal care applications, such as skin and hair treatment formulas and in oral care applications such as dentifrice, denture adhesives, and whitening strips. [00014] In accordance with this invention, the conditioning benefits of hydrophobically modified polysaccharides, preferable hydrophobically-modified cellulose ether polymers, are demonstrated as conditioning agents in personal care compositions such as hair care, -skin care, and oral care compositions as well as household care compositions, such as laundry cleaner and softener products for textile substrates and hard surface cleaner products. [00015] In accordance with the present invention, the functional system substrate is defined as a material that is related to personal care and household care applications. In personal care, the substrate can be skin, hair, teeth, and mucous membranes. In household care products, the substrate can be hard surfaces such as metals, marbles, ceramics, granite, wood, hard plastics, and wall boards or textiles fabrics. [00016] Any water soluble polysaccharide or derivatives can be used as the backbone to form the hydrophobically modified polysaccharide of this invention. Thus, e.g., hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylhydroxyethylcellulose (EHEC), and methylhydroxyethylcellulose (MHEC) and, agar, dextran, starch, and their nonionic derivatives can all be modified. The amount of nonionic substituent such as methyl, hydroxyethyl, or hydroxypropyl does not appear to be critical so long as there is a sufficient amount to assure that the ether is water soluble. The polysaccharides of this invention have a sufficient degree of nonionic substitution to cause them to be water soluble and a hydrophobic moiety including 1) 3-alkoxy-2-hydroxypropyl group wherein the alkyl moiety is a straight or branched chain having 3-30 carbon atoms, or 2) Ca-Cao alkyl, and Cr-Cao aryl, aryl alkyl, and alkyl aryl groups and mixtures thereof, wherein the hydrophobic moiety is present in an amount up to the amount that produces a hydrophobically-modified polysaccharide that shows pronounced syneresis in aqueous solution or in the presence of anionic surfactants such as, for example, lauryl sulfate (LS) and lauryl ether sulfate (LES) surfactants. When the1 hydrophobe is an alkyl moiety, the number of carbons can be 3-30, preferably 6-22, more preferably 8-18, and most preferably 10-16. The aryl, aryl alkyl, or alkyl aryl moiety can have an upper limit carbon amount of 30 carbons, preferably 22 carbons, more preferably 18 carbons, and even more preferably 16 carbons. The lower limit of the carbon amount is 7 carbons, more preferably 8 carbons, and even more preferably 10 carbons. [00017] The preferred polysaccharide backbone is hydroxyethylcellulose (HEC). The HEC which is modified to function in this invention is a commercially available material. Suitable commercially available materials are marketed by the Aqualon Company, a division of Hercules Incorporated, Wilmington, Delaware U.S.A., under the trademark Natrosol®. [00018] The alkyl modifier can be attached to the polysaccharide backbone via an ether, ester, or urethane linkage. Ether is the preferred linkage as the reagents most commonly used to effect etherification because it is readily obtainable; the reaction is similar to that commonly used for the initial etherification, and the reagents used in the reaction are usually more easily handled than the reagents used for modification via the other linkages. The resulting linkage is also usually more resistant to further reactions. [00019] An example of the polysaccharide of the present invention is the 3-alkoxy-2-hydroxypropylhydroxyethylcellulose that shows pronounced syneresis in aqueous solution or in the presence of nonionic surfactants, such as acetylene based surfactants, or in the presence of anionic surfactants such as, for example, lauryl sulfate (LS) and lauryl ether sulfate (LES) surfactants. [00020] The hydrophobic moiety is generally contained in an amount of from about 0.6 wt % to an upper limit amount which renders said hydrophobically modified polysaccharide soluble in a 5 wt- % solution of surfactant, and less than 0..05 wt % soluble in water or in a 1wt% surfactant solution. The alkyl group of the 3-alkoxy-2-hydroxypropyl group can be a straight or branched chain alkyl group having 3 to 30 carbon atoms. Exemplary modifying radicals are propyl-, butyl-, pentyl-, 2-ethylhexyl, octyl, cetyl, octadecyl, methylphenyl, and docosapolyenoic glycidyl ether. [00021] The hydrophobically modified polysaccharide of the present invention is an essential ingredient of the system. An optional'ingredient that may be in the system is a surfactant that can be either soluble or insoluble in the composition. Another optional ingredient is a compatible solvent may also be used in the system that can be either a single solvent or a blend of solvents. [00022] Examples of the surfactants are anionic, nonionic, cationic, zwitterionic, or amphoteric type of surfactants, and blends thereof. Except for cationic surfactants, the surfactant can be soluble o'r insoluble in the present invention and (when used) is present in the composition in the amount of from 0.01 to about 50 wt % by weight of the composition. Synthetic anionic surfactants include alkyl and alkyl ether sulfates. Cationic surfactants can be present in an amount of from 0.01 to about 1.0 wt % [00023] Nonionic surfactants, can be broadly defined as compounds containing a hydrophobic moiety and a nonionic hydrophilic moiety. Examples of the hydrophobic moiety can be alkyl, alkyl aromatic, dialkyl siloxane, polyoxyalkylene, and fluoro-substituted alkyls. Examples of hydrophilic moieties are polyoxyalkylenes, phosphine oxides, sulfoxides, amine oxides, and amides. Nonionic surfactants such as those marketed under the trade name Surfynol® are also useful in this invention. [00024] Cationic surfactants useful in vehicle systems of the compositions of the present invention, contain amino or quaternary ammonium hydrophilic moieties which are positively charged when dissolved in the aqueous composition of the present invention. [00025] Zwitterionic surfactants are exemplified by those which can be broadly described as derivative of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, which can be broadly described as derivative of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, in which the aliphatic radicals can be'Straight or branched chain, and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains as anionic water-solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate. [00026] Examples of amphoteric surfactants which can be used in the vehicle systems of the compositions of the present invention are those which are broadly described as derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical can be straight or branched chain and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic water solubilizing group, e.g., darboxy, sulfonate, sulfate, phosphate, or phosphonate. [00027] According to the present invention, the solvent used in the system should be compatible with the other components of the present composition. Examples of the solvents that may be used in the present invention are water, water-lower alkanols mixtures, and polyhydric alcohols having from 3 to 6 carbon atoms and from 2 to 6 hydroxyl groups. Preferred solvents are water, propylene glycol, water- glycerine, sorbitol-water, and water-ethanol. The solvent (when used) in the present invention is present in the composition at a level of from 0.1 % to 99 % by weight of the composition. [00028] In certain instances, the active component is optional because the dissolved polymer can be the active ingredient component. An example of this is the use of the polymer in a conditioner formulation for hair or skin conditioning or in a fabric conditioner formulation. However, when an active ingredient is needed, it must provide some benefit to the user or the user's body. [00029] In accordance with the present invention, the functional system may be either a personal care product or a household care product. When the functional system is a personal care product that contains at least one active personal care ingredient, the personal care active ingredient includes, but is not limited to, analgesics, anesthetics, antibiotic agents, antifungal agents, antiseptic agents, antidandruff agents, antibacterial agents, vitamins, hormones, antidiarrhea agents, corticosteroids, anti-inflammatory agents, vasodilators, kerolytic agents, dry-eye compositions, wound-healing agents, anti-infection agents, as well as solvents, diluents, adjuvants and other ingredients such as water, ethyl alcohol, isopropyl alcohol, propylene glycol, higher alcohols, glycerine, sorbitol, mineral oil, preservatives, surfactants, propellants, fragrances, essential oils, and viscosifying agents.

Other ingredients that are used in these types of products are well known in the industry. In addition to the above ingredients conventionally used, the composition according to the present invention ban'optionally also include ingredients such as a colorant, preservative, antioxidant, nutritional supplements, alpha or beta hydroxy acid, activity enhancer, emulsifiers, functional polymers, viscosifying agents (such as salts, i.e., NaCI, NH4CI, and KCI, water-soluble polymers, i.e., hydroxyethylcellulose and hydroxypropylmethylcellulose, and fatty alcohols, i.e., cetyl alcohol), alcohols having 1-6 carbons, fats or fatty compounds, antimicrobial compound, zinc pyrithione, silicone material, hydrocarbon polymer, emollients, oils, surfactants, medicaments, flavors, fragrances, suspending agents, and mixtures thereof.

[00037] For a more detailed understanding of the invention, referenced can be made to the following examples which are intended as further illustrations of the invention but are not to be construed in aJimiting sense. All parts and percentages are by weight unless stated otherwise. EXAMPLES [00038] Wet and dry hair combability measurements are typical test methods used to measure conditioning performance in shampoo and conditioner applications. In skin care applications, skin lubricity or reduced friction or softer feel of the skin, reduced water vapor transmission and improved skin elasticity are test methods used to measure skin conditioning. In surfactant-based household cleansing product formulations where conditioning performance is desired, such as dish detergents, fabric softeners, and antistatic products, conditioning refers to imparting a softer feel to fabric and eliminating static effects, eliminating fabric fiber breakage or deformation known as pilling. Imparting color retention properties to fabrics is also important and can be measured. STANDARD TESTING PROCEDURES [00039] Silicone deposition can be measured by several techniques. One technique used for quantifying silicone deposition for Examples of the invention is described as follows: Silicone Deposition Measurement [00040] Each 2-5 gram sample was weighed to the nearest mg, after removal of sample holder, and placed into clean 8 oz jars with approximately 150 ml of methylene chloride. The samples were shaken for 1.5 hours at room temperature. The methylene chloride supernatant was filtered using Whatman #41 filter paper and quantitatively transferred to clean 8 oz jars and evaporated to dryness with mild heat and a nitrogen sparge. Each sample was then dissolved into 2 ml of chloroform-d and quantitatively transferred to a 5-ml volumetric flask. Three chloroform-d rinses were used to transfer each sample to the 5-ml volumetric flask. All flasks were diluted to the mark with solvent and inverted. Each sample was examined in a NICOLET MAGNA 550 FT-IR with 150 co-added scans at 4 cm"1 resolution and 0.4747 velocity using a 0.1 cm-fixed path salt cell. A chloroform-d reference spectrum was used to subtract out the solvent bands (diff=1.0). The silicone level was determined by measuring the peak height of the Si-CH3 stretch at 1260 cm'1 (baseline 1286 and 1227 cm'1) followed by conversion to mg/ml of silicone using a low level calibration curve extending from 10 - 300 parts per million (ppm). Each sample was corrected for dilution volume and sample weight. All values are reported to the nearest ppm.

Use 76 grams premix per 100 grams shampoo Procedure for Preparing Silicone Shampoos from Premix Formulation I -Lightly Bleached European Medium Brown Hair [00041] 76 grams of Formulation I surfactant premix were weighed into a 4-oz. glass jar. 10 grams of 2 wt % polymer solutions and 9 grams additional water where then weighed into the 4-oz. jar containing the 76 grams Formulation I surfactant premix. The 4-oz jar was then clamped into a 60° C water bath. A twin-propeller mixer was lowered into the jarand the jar opening was covered with a lid to reduce evaporation loss. [00042] The sample was stirred for 15-minuteS. After the 15-minutes of stirring, 0.25 g of NH4CI (ammonium chloride Baker reagent) was added to the jar. The sample was then stirred for an additional 45 minutes while covered. The sample jar was then removed from the 60°C bath. The jar was then clamped into a room temperature water bath. The overhead stirrer was reattached and the stirring of the sample was begun in the water bath. The sample was allowed to stir for a minimum of 5-minutes. This was sufficient time for the sample temperature to drop below 35°C. [00043] 3.68 g of dimethicanol GESM555 silicone was added to the jar and the jar was stirred for a minimum of 5-minutes additionally. 0.5 g of Germaben® II product was added to the jar and the jar was stirred for an additional minimum amount of time of 5-minutes. [00044] The pH was checked and adjusted to 6.2-6.5 ( either a 10 % or 50 % solution of citric acid was used to lower the pH). The jar was sealed and centrifuged for about 10-minutes at 3,000 rpm to remove any entrapped air. [00045] The Brookfield-viscosity equilibration was measured for 1 hour on a Brookfield LV-4, at 25.0°C, @ 0.3 RPM, then 12 RPM, then 30 RPM. A 3-minute rotation time was used at each speed. Procedure for Preparing Silicone Shampoos from Premix Formulation I -Virgin European Medium Brown Hair [00046] The same premix Formulation I was used to prepare shampoos for testing on virgin brown hair, however, the polymer concentration in the shampoo was 0.4 wt %, the amount of ammonium chloride used in these shampoos was 1.0 gram, and the amount of silicone used was 2.45 g GE SM555 dimethicanol. Wet/Dry Comb Performance Measurement- Lightly Bleached European Medium Brown HairConditions: [00047] Measured at constant temperature and humidity (72 deg. F and 50 % relative Humidity) Equipment: [00048] Instron 1122 (2-lb. load cell, 500-gram range used) Procedure: [00049] Each tress was washed twice with SLS using the standard washing/rinsing procedure. [00050] The twice washed tress was hand combed 5-times with large teeth comb and 5-times with small teeth comb. (10X total) No Instron testing of SLS-washed tresses The washed tresses were allowed to sit overnight. No dry-combing 1. Each tress was shampooed twice with the agreed upon shampoo amount. (0.5 g shampoo per 1 gram tress (all tresses were 3.0 g) 2. Each shampooed tress was hand combed twice with a large teeth comb. 3. The hand combed twice tress was loaded into a Instron instrument and the crosshead was lowered to bottom stop. The tress was combed twice with small teeth comb and placed into double-combs. The Instron was run under standard conditions. After the test was run, the tress was sprayed with Dl water to keep moist. Do not hand-comb tress. Using a paper towel, wipe excess liquid off double-combs. Return crosshead to bottom stop and replace tress into double-combs. Rerun under standard conditions. A total of eight tests were run on each tress. 4. After the eight tests were finished, the tress was hung up overnight. 5. The next day, each tress was dry combed tested eight times. No hand combing of dry tresses was done. 6. Averaged wet comb energy for 40 Instron runs and reported average with standard deviation. 7. Averaged dry comb energy for 40 Instron runs and reported average with standard deviation. [00051] A similar combing protocol was used for virgin hair, but only two tresses were used, and the average reported from the two tresses combed 5 times per tress, with more precombing of the tresses prior to measurement. [00052] Several examples of the above technologies were demonstrated in the following Examples 1-6 in shampoo Formulation I using the standard combing protocol on bleached hair and virgin brown hair. This formulation is shown only for example and other formulations containing other silicones, or other oils, such as mineral oil or any other commonly used conditioning oil, humectants such as glycerol, or conditioning ingredients, such as panthenoic acid or derivatives can be included. Measurement and Calculation of Alkyl Ether Content [00053] The alkyl ether content of the substituted cellulose ethers shown in the examples is determined by reacting a sample with concentrated hydriodic acid at elevated temperature to produce alkyl iodides at temperatures of about 185C for 2 hours. The reaction products are extracted in situ into a solvent (o-xylene) and the alkyl iodides are quantified by gas chromatography. This is the so called sealed tube Zeisel - GC technique. The amount of alkyl iodide produced by the sample is converted into the desired equivalent alkyl compound or functional group by multiplying by the ratio of molecular weights: Species A x (mw B / mw A) = Species B Specifically for cetyl content: % cetyl iodide x mw cetyl / mw cetyl iodide = % cetyl % cetyl iodide x 225.45 / 3552.35 = % cetyl Molecular Weight [00054] Weight average molecular weights were determined using aqueous size exclusion chromatography. Example 1 [00055] A gel of a water-soluble cetyl-modified hydroxyethyl cellulose (C16 HMHEC, 1.14wt % cetyl substitution, 3.8 molar hydroxyethyl substitution, Mw=824,000 Dalton) that formed above 1.5-2 wt % polymer concentration and underwent syneresis upon dilution in water was used in this Example and showed very good efficacy in a 2-in-1 conditioning shampoo without the need for any cationic moiety and without depositing any silicone. For bleached hair, wet hair comb energy was reduced 30 % relative to the wet comb energy for the no polymer control shampoo, and silicone deposition was less than 10 ppm. Wet comb energies for the shampoo containing the cationic guar benchmark, NHance® 3916 product, were reduced 40 % relative to the no polymer shampoo. [00056] This Example demonstrates that the nonionic hydrophobic polymer that undergoes syneresis in aqueous solution or in the shampoo on dilution can achieve nearly 75 % of the wet comb energy"reduction achieved by the cationic polymer. The dry comb energies for the tresses treated with a shampoo containing the polymers of the invention were equal to the dry comb energy measured on tresses treated with the shampoo containing no polymer and the shampoo containing cationic guar. Example 2 [00057] A water-soluble C16 HMHEC (1.04wt% cetyl substitution, 4.0 molar hydroxyethyl substitution, Mw = 1,200,000 Dalton) was used in this Example. This polymer formed a gel at 3-4 wt % polymer in water but showed syneresis at 2 wt %, was dissolved in 5 wt % ammonium lauryl sulfate to give a clear solution, and underwent syneresis upon dilution with water. This polymer showed very good efficacy in 2-in-1 conditioning shampoos without the need for any cationic moiety and without depositing any silicone. For bleached hair, wet hair comb energy was reduced by 28 % relative to the no polymer control shampoo, and silicone deposition was less than 10 ppm. Wet hair comb energy reduction was 70 % of the wet comb energy reduction achieved by cationic guar. The dry comb energies for the tresses treated with a shampoo containing the polymers of the invention were equal to the dry comb energy measured on tresses treated with the shampoo containing no polymer and the shampoo containing cationic guar. Example 3 (COMPARATIVE) [00058] A shampoo was made with a water-soluble cetyl-modified hydroxyethyl cellulose (Polysurf® 67 product, 0.5 wt % cetyl substitution, 2.5 molar hydroxyethyl substitution, Mw=830,000 Dalton) that did npt form a gel above 1.5-2 wt % polymer concentration and did not undergo syneresis uppn dilution in water. For bleached hair, wet hair comb energy was reduced by 13 % relative to the wet comb energy for the no polymer control shampoo, and silicone deposition was less than 10 ppm. [00059] This Example demonstrates that the nonionic hydrophobic polymer that does not undergo syneresis does not show as good efficacy in the 2 - in -1 conditioning shampoo as a polymer that undergoes dilution deposition (Examples 1-3). The dry comb energies for tresses treated with a shampoo containing the commercial Polysurf 67 product was equivalent, within standard deviation, of the dry comb energy measured on tresses treated with the shampoo containing no polymer and the shampoo containing cationic guar. Example 4 (COMPARATIVE) [00060] A HMHEC polymer that was water-insoluble (2.82 wt % cetyl substitution, 3.83 molar hydroxyethyl substitution, dissolved with added surfactant in shampoo, yet did not undergo syneresis upon dilution and hence showed low efficacy in wet comb reduction. For bleached hair, wet hair comb energy was reduced by 11 % relative to the wet comb energy for the no polymer control shampoo, and silicone deposition was less than 10 ppm. The dry comb energies for the tresses treated with a shampoo containing this polymer were equal to the dry comb energy measured on tresses treated with the shampoo containing no polymer and the shampoo containing cationic guar. This Example demonstrates that water-insolubility is not a defining criteria for performance, and syneresis of the water-insoluble polymer is required for performance. Example 5 [00061] A gel of a water-soluble methylphenylglycidyl hydroxyethyl cellulose ether, (6.3 wt % methylphenyl substitution, 2.5 molar hydroxyethyl substitution, Mw = 350,000 Dalton), formed a gel above 1.5-2 wt% polymer concentration and underwent syneresis upon dilution in water and showed good efficacy in 2 in -1 conditioning shampoos without the need for any cationic moiety and depositing less than 30 ppm silicone. For virgin medium brown European hair, wet hair comb energy reduction was 72% of the wet comb energy reduction achieved by cationic guar. A silky feel was imparted to the hair. [00062] Wet comb energy for the shampoo containing the cationic guar benchmark, NHance® 3916 product, was reduced 61 % relative to the no polymer shampoo, with greater than 40 ppm silicone deposited. This Example demonstrated that the nonionic hydrophobic polymer that undergoes syneresis in aqueous solution or in the shampoo on dilution can achieve nearly 74 % of the wet comb energy reduction achieved by the cationic polymer on virgin hair, with less silicone deposition. The dry comb energies for the tresses treated with a shampoo containing the polymer of the invention were equal to the dry comb energy measured on tresses treated with the shampoo containing no polymer and the shampoo containing cationic guar. Examples 6-28 [00063] Simple conditioning tests were performed evaluating polymers of the invention and some commercial polymers on mildly bleached hair using a fully formulated rinse-off conditioner (Examples 6-16 ) and aqueous solutions of the polymers (Examples 17-28). The Instron comb test described below was used to generate the data shown in these Examples. Comparison of the wet and dry comb energy Example 16 with other Examples in the Table demonstrated that the polymer of the invention delivered the lowest combined wet and dry comb energies of all nonionic and hydrophobic polymers tested and-approached the wet and dry comb energies delivered by cationic polymers of Example 8. In Table 2, comparison of the wet and dry comb energy Example 28 with other examples in the Table 2 demonstrated that the polymer of the invention delivered the lowest combined wet and dry comb energies of all nonionic and hydrophobic polymers tested and approached the wet and dry comb energies delivered by cationic polymers of Examples 18-20. Polymers as a conditioner in Fully Formulated Conditioning Formulation - TABLE 1 [00064] Natrosol® hydrqxyethyl cellulose type 250HHR was added to water under agitation. Next, pH was adjusted to 8.0 to 8.5. The slurry was stirred for about 30 minutes or until polymer dissolved. Next, polymer of this invention or a commercial comparative polymer listed in TABLE 1 was added and mixed for 30 more minutes. The solution was heated to about 65°C and stirred until it became smooth. Cetyl alcohol was added and mixed until it mixed homogeneously. The mixture was cooled to about 50°C and then potassium chloride was added. Next, isopropyl myristate was added and mixed until the mixture looked homogeneous. The pH of the mixture was adjusted between 5.25 to 5.5 with citric acid and/or NaOH solution. The conditioner was preserved with 0.5 % preservative and mixed until it reached room temperature. 90.94 g Deionized water 00.70 g Natrosol® 250HHR 00.20 g Polymer of this invention or commercial polymer 02.00g Cetyl alcohol 00.50 g Potassium Chloride 02.00g Isopropyl Palmitate As required - Citric acid to adjust pH As required - Sodium hydroxide to adjust pH 00.50 g Preservative [00065] About three grams in weight flat tresses of mildly bleached European hair from International Hair Importers and Products Inc. of Glendale, NY were used for measuring wet and dry combing performance of various formulations of this experiment. To clean the hair tress, trie hair tress was first wetted with 40°C tap water and then 5.0 ml of sodium lauryl sulfate solution was applied along the tress length. Tress was kneaded for 30 second. Tress was then rinsed under 40°C running water for 30 seconds followed by rinsing with room temperature tap water for 30 seconds. The tress was then dried overnight. Next day, the tress was rewetted with 40°C tap water. Next, 0.5 gram of test conditioner per gram of hair was applied uniformly along the length of hair. Tress was kneaded for 30 second and then it was rinsed under 40°C running water for 30 seconds. The conditioner was reapplied along the length of the tress and the tress was kneaded for 30 second; then, it was rinsed under 40°C running water for 30 seconds. The tress was rinsed with room temperature tap water for 30 seconds. The tress was combed immediately eight times and from the data average amount combing energy in gram force-mm/gram of hair (gf-mm/g) required to comb the hair was calculated. The tress was stored overnight at about 50 % relative humidity and about 23°C. Next day, the tress was first combed with fine teeth rubber comb to free-up hair stuck together. Again, the hair tress was combed eight times to determine the average force required to comb one gram of dry hair. The higher the number the poorer the conditioning effect of the polymer being tested. Two tress'es were used per conditioning formulation. The data reported below are average of two tresses.

Examples 41-51 [00071] A body wash formulation was prepared using the polymer of the invention (Example 43) with a polymer-free control (Example 41) and with formulations containing commercial nonionic, hydrophobic, and cationic polymers. The polymer of the invention (Example 43) showed better compatibility with the body wash components than the nonionic commercial polymers (Examples 48 and 50). The commercial hydrophobic polymers conveyed an applesauce texture to the formulation, as did the polymer of the invention. This result suggests that these polymers could be used at a lower concentration in this formulation. Body Wash Table 4 [00072] Body wash preparation: An aqueous stock solution of each polymer was first prepared at 1.0 % concentration. For polymers: N-Hance® 3215, ADPP6503, AQU D3799, and AQU D3939 solutions were made by adding polymer to water under vigorous agitation. Next, the pH was lowered to between 6 to 7 with citric acid and the solution was mixed for an hour or until the polymer solubilized. The solutions were preserved with 0.5 %. Glydant® product. For the polymers ADPP6531, ADPP5922, AQU D3869, AQU D3673, ADPP6582 ADPP6626, Polysurf®67, Natrosol® plus 330, Natrosol® 250HHR, Natrosol® 250M, UCARE® JR30M, UCARE® JR400, AQU D3686 ADPP6641, the polymers were added to well agitated water and then the pH was raised to 8.5 to 9.5 using sodium hydroxide. The solution was mixed for an hour and then the pH was lowered to between 6 to 7 using citric acid. [00073] Body wash stock solution was prepared by adding to vessel 46.4 grams of sodium laureth sulfate, 27.0 grams of sodium lauryl sulfate, 6.7 grams of Gg-Ci5 alkyl phosphate, 4.0 grams of PPG-2 hydroxyethyl cocamide, 1.0 gram of sodium chloride, 0.30 gram of tetra sodium EDTA, and 0.5 gram of DMDM hydantoin in the order listed while mixing. Each ingredient was allowed to mix homogeneously before adding the next ingredient. The totaj stock solution weighed 85.9 grams. [00074] Body wash was prepared by adding 20 grams of polymer (listed in Table 4) solution to 80 grams of the above body wash stock solution while mixing. Next, the body wash pH was adjusted to between 6 and 7 with citric acid. The body wash viscosity was measured using the Brookfield LVT viscometer. The viscosity was measured at 30 rpm once the body wash conditioned for at least two hours at 25°C. The body wash clarity was also measured at 600 nm using a Spectrophotometer, Gary 5E UV-VIS-NIR, available from Varian Instruments, Inc. The clarity measurements at 600 nm wavelength are reported as %T value. The higher the number, the clearer is the solution. Lather Drainage Test: [00075] Objective of this Test is to measure the lather drainage time of a diluted body wash solution. Long drainage times indicate a rich, dense lather with good stability. The Test was used to determine the influence that the polymers of this invention may have on lather quality. Equipment: [00076] Waring® Blender Model #7012 or 34BL97 or equivalent.

Standard Testing Sieve NO.20 or Tyler® Equivalent 20 mesh or 850 micrometer or 0.0331 inch sieve. Preferably over 7 inch in diameter but smaller size could also be used [00079] Stopwatch or a timer. Procedure: [00080] For each test formulation, 1,000 g of a diluted body wash solution was prepared as shown below. Body wash 66.13 g Deionized Water 933.87 g Total 1,000.00 g 1. For each lather test measurement 200 grams of above diluted solution was weighed and placed in a 25° C water-bath for 2 hours. Three jars (each with 200 grams of solution) were prepared per body wash formulation. 2. Next, the lather drainage time for each solution was measured using the procedure described below. a. 200 g of solution were poured into a clean, dry Waring blender glass vessel. b. The solution was blended at the highest speed for exactly 1 minute while covered. c. Foam generated in the jar was immediately poured into a clean, dry funnel standing on a 20 mesh screen over a beaker. d. Foam from the blender was poured for exactly 15 seconds. The goal was to get as much foam as possible into the funnel without overflowing. After 15 seconds, stopped pouring foam, however, the stopwatch was kept running. e. The total time needed for the foam to drain including the 15 seconds for pour time was recorded once the wire was no longer covered by foam or liquid. Table 4 (Table Removed) (10) c.
