FORM 2 THE PATENTS ACT, 1970 (39 of 1970) COMPLETE SPECIFICATION (See section 10; rule 13) 1. Title of the invention. 2. Applicant SUSPENDING CLEAR CLEANSING FORMULATION (a) Hindustan Lever Limited (b) of Hindustan Lever House, 165/166 B (c) ackbay Reclamation, Mumbai 400 020, Maharashtra, India (d) an Indian Company ; The following specification (particularly) describes the nature of this invention (and the manner in which it is to be performed). This application claims the benefit of U.S. Provisional Shower gel formulations which are mild to the skin are well known in the art. Such a formulation may optionally contain skin feel agents, such as cationic polymers. However, when one desires to suspend particulates and/or beads in the formulation, frequently substantial quantities of anionic surfactants have been incorporated, and provide clear solutions. Unfortunately, the addition of such anionic surfactants diminishes the mildness of the shower gel formulation. U.S. Patent No. 5,656,257 (Fealy et al., issued on August 12, 1997), which is here incorporated by reference, discloses an anionic shampoo and conditioning composition comprising an oily conditioning agent, a shampooing agent, and an acrylate copolymer, a cationic conditioning agent and water. In this formulation, the acrylate copolymer is used to suspend the anionic shampooing and cationic conditioning agent and prevent it then from inactivating one another. U.S. Patent No. 5,656,257 does not, however, disclose a clear, mild cleansing composition containing a combination of surfactant types, which is capable of suspending beads or other insoluble particulates or gas bubbles. 2 U.S. Patent No. 4,552,685 (Kernstock et al., issued November 12, 1985), which is here incorporated by reference, discloses examples of useful acrylate polymers and copolymers capable of thickening mild cleansing agents containing amphoteric surfactants and betaines. However, there is no teaching in that patent regarding the compatability of cationic polymer conditioning agents in the formulation, nor the suspending power of the solution for insoluble beads, particulates or gaseous bubbles. U.S. Patent No. 3,759,861 (Shimokawa, issued September 18, 1973), which is here incorporated by reference, discloses a clear polymer adhesive complex of an acrylate containing polymer and surfactant used to produce a flocculant. However, there is no disclosure of a shower gel or other cleansing composition containing a cationic conditioning agent or complex which can suspend particulates or gas bubbles. The present invention comprises a shower gel formulation having a clear appearance and which suspends beads (e.g. agar/Ti02/sunflower oil beads), insoluble particles and gas bubbles while having one or more acrylate copolymers, a betaine or other amphoteric surfactant and a cationic polymer (e.g. guar) present in the formulation." It is "known that anionic acrylates (i.e. Aculyn type acryiates (available from ISP)), being anionic polymers are generally considered to be incompatible with cationic charged irgradients. It is further known that polymeric cationics, as well as some large, bulky quaternary 3 materials, can possibly be incorporated in formulations containing such acrylates. The optimum order of addition in these instances generally requires the acrylate to be neutralised with a base prior to the addition of any cationics. The applicants have discovered that a clear or transparent product can be produced by either partially neutralising such acrylates prior to cationic addition or after cationic addition. Clarity or transparency is herein defined as having a turbidity less than or equal to 105 NTU (Nephelometric Turbidity Units). The applicants have further discovered that amphoteric surfactants, such as betaine (which is also cationic in nature and not a true amphoteric), may be optionally added to the inventive formulation in the range of 0.01 - 15 weight percent, preferably 1-10 weight percent to increase mildness without creating noticeable haziness. Prior art shower gels that suspend beads or particulate matter are primarily composed of anionic surfactant and structurant which in most cases are harsher than the inventive formula. In one embodiment, the present invention provides an aqueous, clear shower gel which is capable of suspension, comprising: About 10-20 weight percent of at least one anionic surfactant. 4 About 2-15 weight percent of an least one betaine or othe amphoteric surfactant; About 2-15 weight percent of at least one acrylate copolymer; About 0.05 - 2 weight percent of at least one cationic polymer; About 0.1-5 weight percent of beads or particulates; About 0.1-5 weight percent of a benefit agent such as a water soluble or dispersible silicone polymer; About 0.1-2 weight percent of a preservative such as a biocide; In another embodiment, the present invention provides an * aqueous, clear cleansing gel that is capable of suspending insoluble material or gas bubbles, comprising: a. about 5 to 30, preferably 8 to 20 weight percent of at least one anionic surfactant; b. about 2 to 15, preferably 2 to 10 weight percent of at least one amphoteric surfactant; c. about 0.1 to 10, preferably 0.5 to 5 weight percent of at least one acrylate copolymer; c. about 0.01 to 5, preferably 0.1 to 2 weight percent of at least one cationic polymer; e. about 0.01 to 5, preferably 0.05 to 3 weight percent of at least one insoluble corroonent A selected from the group consisting of beads, particulates, water insoluble liquids and gas bubbles; f. about SO to 85 weight percent of water g. about 1.9:1 to 15:1, preferably 1.9:1 to 10:1 weight percent ratio range of anionic surfactant to amphoteric surfactant; h. about 0.1:1 to 15:1, preferably 0.3:1 to 10:1, weight percent ratio range of the sum of cationic polymer and amphoteric surfactant to acrylate copolymer; and wherein the concentration of acrylate copolymer is sufficient to suspend said at least one insoluble component, preferably wherein the viscosity range is between 6,000 and 20,000 cps, and the pH is in the range of 5,5 to 7.0. In a further embodiment, the present invention provides an aqueous, clear cleansing gel which is capable of suspending insoluble material or gas bubbles, comprising: a. about 5 to 30, preferably 8 to 20 weight percent of at least one anionic surfactant; b. about 0.1 to 10, preferably 0.5 to 5 weight percent of at least one acrylate copolymer; c. about 0.01 to 5, preferably 0.1 to 2 weight percent of at least one cationic polymer; d. about 0.01 to 5, preferably 0.05 to.3 weight percent of at least one insoluble component selected from the group consisting of beads. 6 particulates, water insoluble liquids and gas bubbles; e. about 50 to 85 weight percent of water; and wherein the concentration of acrylate copolymer is sufficient to suspend said at least one insoluble component/ preferably wherein the viscosity range is between 6,000 and 20,000 cps, and the pH is in the rangeof 5.5 to 7.0.

Ingredient: % by weight Anionic surfactant (e.g. Sodium Laureth Sulfate (3E0) About 10-20 Betaine (e.g. Cocoamidopropyl betaine) About 2-15 Acrylate Copolymer (e.g. Aculyn 33 and 22) About 2-15 Silicone (e.g. Dimethicone Copolyol Sulfosuccinate About 0,1-5 Fragrance About 0-1.0 Cationic surfactant (e.g. Hydroxypropyl Guar Hydroxyoropyl Trimonium Chloride) About .05-5 ProDylene Glycol About 0.1 - 2.0 Preservative About 0.1 - 2.0 Sodium Hydroxide to adjust pH to 6.0 to 7.0 Beads (e.g. Agar/ Titanium Dioxide/Sunflower Oil Beads About 0.1 - 2.0 Water q.s. to 100 I 24 METHODS Viscosity For the purposes of this invention, viscosity is measured using conventional techniques with a Brookfield viscometer, Model HBDVII+ CP, spindle No. 41 at 0.5 rpm at 25°C. Turbidity For the purposes of this invention, the acceptability of formulation clarity was measured qualitatively and quantitively using a visual method of turbidity determination and a turbidimeter respectively. Briefly, the visual method involves looking through a determined path length of the formulation to a visual target and determining if the visual target is legible or recognizable. This target may be a straight line, a set of parallel lines, or a number or letter printed on white paper. To assess turbidity, the test formulation was placed in a glass beaker such that the height from the bottom of the beaker to the top surface of the formulation was 10.16 cm (four inches). The formulation is made free of air bubbles. A piece of paper with the visual target is placed under the beaker. The assessor the looked through the top surface of the formulation to the visual target. If the visual target appeared similar to the original, the formulation "is of acceptable clarity and receives a "pass" rating. If the visual target appeared significantly hazy, cr is out of focus compared to the original target, the formulation is of unacceptable clarity and receives a "fail" rating. 25 Turbidity was quantitatively determined by a Turbidimeter, Model DRT-100D, manufactured by Shaban Manufacturing Inc, H. F. Instruments Division using a sample cuvette of 28 mm diameter by 91 mm in length with a flat bottom. Samples that had received a "pass" rating from the visual method were found to have a turbidity measurement of less than or equal to 105 NTU"s (Nephelometric Turbidity Units). Samples that had received a "fail" rating from the visual method were found to have a turbidity measurement of greater than 105 NTU"s. The foregoing description and examples illustrate selected embodiments of the present invention.
