BODY SURFACE PROTECTING COMPOSITION TECHNICAL FIELD [0001] The present invention relates to a composition that is used in applications to prevent or reduce disorders on a body surface (skin, hair, and the like), specifically relates to a body surface protecting composition. In particular, the present invention relates to a body surface protecting composition which has the excellent effects of accelerating the recovery of the barrier functions of skin and hair, and preventing degradation of those functions. BACKGROUND ART [0002] Skin barrier functions include a function that prevent invasion by foreign matter from outside the skin into a body, and a function that prevents water content in the body from escaping to the outside. When the barrier function of the skin is degraded, rough skin or inflammation of the skin such as rash can result from external stimulation, and dry chapped skin can result from an increase in the transpiration of water from the skin, and therefore itchiness and skin trouble can easily occur. Furthermore, the barrier function of the hair is primarily a function of preventing water and aqueous components from escaping to the outside. When the barrier function of the hair is reduced, the tensile strength and viscoelasticity of the hair will be degraded, the feel on the skin will be poor, hair styling will be difficult, and not only will this induce a deterioration in appearance such as luster, but will also cause damage such as split ends and broken hair. [0003] Conventionally moisturizing agents have been added to cosmetic materials in order to improve and prevent this type of dry condition in skin and hair. For example, patent document 1 discloses a cosmetic material for skin that contains a polyol such as glycerin or ethylene glycol, or urea, hyaluronic acid or an amino acid or the like as a moisturizing agent. However, with these cosmetic materials, the effect is temporary and is insufficient for resolving the aforementioned problems. Furthermore, this cosmetic material is not used for applications to reduce and prevent damage to the surface of the body, and there is no comment whatsoever concerning an effect of accelerating improvements in the barrier function of the skin or preventing a degradation in that function. Furthermore, according to recent dermatological research, simple application of a moisturizing agent onto the surface of skin will increase the moisture of the skin for a short period of time, but in actuality may hinder the intrinsic function of the skin to retain moisture in the skin, and is known to damage the condition of the skin. [0004] Furthermore, patent document 2 for instance discloses a composition comprising an anionic surfactant with two chains and two hydrophilic groups, and discloses the use as a cosmetic material with moisturizing effects. However, this composition is also not used for applications to reduce and prevent damage to the surface of the body, and it dose not disclose any effect of accelerating improvements in the barrier function of the skin or preventing any degradation in that function, and does not disclose a compound that has those effects. [0005] Furthermore, patent document 3 discloses a moisture retaining composition which does not feel sticky by the combined use of a double chain amide compound with a polyhydric alcohol. However, this moisture retaining material is essentially a polyhydric alcohol, and similar to patent document 1, is not used for applications to reduce and prevent damage to the surface of the body, and it does not disclose any effect of accelerating improvements in the barrier function of the skin or preventing a degradation in net function, and only discloses the fact that a double chain amide compound works to reduce the stickiness when the composition is applied. [0006] Patent document 4 discloses a composition with low irritability that contains an anionic surfactant with a double chain bipolar acyl group, but it only disclose the low irritability of the composition, and dose not disclose any application for preventing or reducing damage to the surface of the body, nor any effect of proactively accelerating an improvement of the skin barrier function or preventing a degradation of that function. [0007] Patent document 5 discloses an agent to improve skin damage and metabolic disorders using a Gemini type surfactant, but the Gemini surfactant disclosed in this document is only a carrier for transporting physiologically active materials through skin or membrane, and does not show an effect of accelerating an improvement in the skin barrier function or preventing deterioration of that function. [0008] On the other hand, a type of sphingolipid such as ceramides obtained either naturally or synthetically are well-known as substances which improve the skin barrier function, and for example, patent document 6 discloses a liquid crystal composition using various types of ceramides, patent document 7 discloses an external medicine that contains ceramides or substances with a structure similar to a ceramide, and patent document 8 discloses a skin care agent that contains ceramides, and discloses a composition that improves skin turn over, improves skin roughness, and has excellent permeability and moisture retaining properties. However, all of the ceramides used in these inventions have low water solubility, and not only cause difficulty when creating a composition, but also require improvisations in order to permeate into the skin and hair, and cause restrictions on the degree of freedom of the formulation. [0009] Therefore there is demand for a raw material which has a strong effect at accelerating the recovery of the barrier function of skin and hair or in other words the surface of the body, and has good water solubility. [0010] On the other hand, in patent document 9, the present inventors have disclosed a surfactant consisting of a composition containing an acyl group comprising an N-long chain acyl acidic amino acid derivative made by reacting N- long chain acyl acidic amino acid anhydride with at least one compound selected from compounds which have m functional groups of at least one type selected from a group consisting of a hydroxyl group, an amino group, and a thiol group in the molecule, as well as a manufacturing method thereof. In this publication, the surfactant obtained provides surface activity at low concentrations and has been confirmed to have low irritability. Patent document 1 Japanese Patent Application Laid-open No.2000-191499 Patent document 2 Japanese Patent Application Laid-open No. H10-218754 Patent document 3 Japanese Patent Application Laid-open No. H10-203956 Patent document 4 Japanese Patent Application Laid-open No. H10-219278 Patent document 5 WO2005/39642 Patent document 6 Japanese Patent Application Laid-open No. H9-124432 Patent document 7 Japanese Patent Application Laid-open No. H5-213731 Patent document 8 Japanese Patent Application Laid-open No. 2001-39859 Patent document 9 Japanese Patent Application Laid-open No. 2002-167313 DISCLOSURE OF INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION [0011] An object of the present invention is to provide a body surface protecting composition which has an excellent effect of accelerating recovery of the barrier function of skin and hair when that function has deteriorated due to skin trouble or the like. [0012] As a result of diligent investigations, the present inventors have discovered that a multi-chains and multiple hydrophilic group-type compound that has two or more hydrophobic groups and two or more hydrophilic groups in a molecule has an excellent effect of improving the barrier function of the skin and hair that is required because of skin trouble or the like. [0013] As described above, this multi-chain multiple hydrophilic group-type compound is known to be a surfactant, but the effect of improving the barrier function of skin and hair is entirely unknown. Furthermore, single chain single hydrophilic group-type compounds which have essentially the same basic constitutional units as multi-chain multiple hydrophilic group-type compounds can not provide the effect of accelerating recovery of the barrier function of skin, and conversely cause the barrier function to deteriorate. Therefore, it was unexpected that multi-chain multiple hydrophilic group-type compounds have the effect of improving the barrier function of skin and hair. [0014] Furthermore, the present inventors have discovered that the effect of improving the barrier function of skin and hair with the present invention is increased when the multi-chain multiple hydrophilic group-type compound forms a liquid crystal, and the liquid crystal formation is facilitated by combining a oil-based component with the multi-chain multiple hydrophilic group-type compound. [0015] In other words, the present invention is a body surface protecting composition comprising, (A) at least one type of multi-chain multiple hydrophilic group-type compound having two or more hydrophobic groups and two or more hydrophilic groups in the molecule. [0016] In the multi-chain multiple hydrophilic group compound of (A), it is preferable that at least one of the hydrophobic groups is an acyl group, and at least one of the hydrophilic groups is a carboxyl group, sulfonate group, sulfate ester group, phosphate ester group, or a salt thereof, and it is more preferable that the aforementioned multi-chain multiple hydrophilic group-type compound further has an amino acid residue in the molecule. [0017] Furthermore, a preferred multi-chain multiple hydrophilic group-type compound of (A) is a compound expressed by the following formula (1). [0018] [C1] Qn-X • • • (1) [0019] (In formula (1), X represents a spacer with a molecular weight of one million or less, has m functional group residues that may be the same or different, and may have other functional groups. Q represents a functional group as expressed by the following formula (2), the functional groups may be the same or different.

Furthermore, m is an integer such that m > n.). [0022] In particular, the aforementioned multi-chain multiple hydrophilic group-type compound of (A) preferably is a compound expressed by the following formula (3). [0023] [C3] [0024] (In formula (3), R11 and R12 each independently represent a hydrocarbon group which may be substituted with a saturated or unsaturated substitution group of from 8 to 20 carbon atoms, R21 and R22 each independently represent either a hydrogen atom or a lower alkyl group of from 1 to 3 carbon atoms that may be substituted with a substitution group, each Y' independently represents a carboxyl group or a salt thereof, each W independently represents -0-, -S-, or -NR'- (where R' represents a hydrogen atom or a hydrocarbon group of from 1 to 10 carbon atoms which may be substituted with a substitution group), and T represents a spacer of from 1 to 20 carbon atoms, j1, j2, k1, and k2 independently represent either 0, 1, or 2, but j1 and k1, and j2 and k2 cannot be both 0 at the same time.). [0025] Furthermore, the multi-chain multiple hydrophilic group-type compound of (A) preferably forms a liquid crystal, and therefore the body surface protecting composition also preferably comprise an oil component (B).

[0048] X preferably has from 1 to carbons, more preferably from 1 to 20 carbons. Furthermore, X is preferably in a naturally existing form, because the biodegradability will be excellent. [0049] When X is an amino acid residue, the affinity of the compound expressed in formula (1) towards skin and hair will be high, and the compound expressed in formula (1) will easily permeate into skin and hair so the effect of improving the barrier function will be further accelerated. [0050] In formula (1), Q is a substitution group expressed in formula (2), and each functional groups may be the same or different. [0051] • [C5] [0052] In formula (2), R1 represents a hydrocarbon group that may be substituted with a saturated or unsaturated substitution group of from 2 to 20 carbon atoms, and may be a straight chain, branched chain, or ring. A saturated or unsaturated hydrocarbon group of from 8 to 20 carbon atoms is preferable. [0053] In formula (2), R2 represents a hydrogen atom or a lower alkyl group of from 1 to 3 carbon atoms such as a carboxyl group, a sulfonate group, a sulfate ester group, a phosphate ester group, or salts thereof, and may also be substituted. Examples include a methyl group, an ethyl group, a propyl group, an isopropyl group, a hydroxymethyl group, a hydroxyethyl group, a hydroxy(iso)propyl group, a dihydroxy(iso)propyl group, a carboxymethyl group, a carboxyethyl group, a carboxypropyl group, and a sulfoethyl group.

[0055] In formula (2), Z is a site of a bonding with a functional group residue contained in X. [0056] A preferred substitution group Q expressed in formula (2) is a residue of an N-acylated acidic amino acid because the effect of improving the barrier function of the skin and hair will be further enhanced. Acidic amino acid as used in the present invention refers to a monoaminodicarboxylic acid having 2 carboxyl groups and 1 amino group present in a molecule, and the amino group may be an N-methyl group or an N-ethyl group. The substitution group Q expressed in formula (2) can be any optical isomers of a D-isomer, L-isomer or racemic body, but Q is preferably a residue of an L-acidic amino acid compound because the biodegradability will be excellent. [0057] Examples of acidic amino acids include glutamic acid, asparatic acid, lanthionine, ß-methyllanthionine, cystathionine, diencolic acid, felinine, aminomalonic acid, ß-oxyasparginic acid, a-amino-a-methylsuccinic acid, ß-oxyglutamic acid, ?- oxyglutamic acid, ?-methylglutamic acid ?-methyleneglutamic acid, ?-methyl-?- oxyglutamic acid, a-aminoadipic acid, a-amino-?-oxyadipic acid, a-aminopimelic acid, a-amino-?-oxypimelic acid, ß-aminopimelic acid, a-aminosuberic acid, a- aminosebacic acid, and pantotenic acid. [0058] The top layer of human skin and hair is a layer known as the horny layer, and this horny layer consits of cells that have been keratinized (keratinized cells), and "intercellular lipids" that fill in the gaps of the cells. The barrier function of the skin is thought to be primarily dependent on the "intercellular lipids", and these "intercellular lipids" are primarily made of ceramides, and align in plane to adopt a "lamellar structure" that retains moisture between the structural elements. Degradation of the barrier function of skin and hair is thought to be caused by a loss of ceramides from the horny layer for some reason, and by disorganizing of the lamellar structure of the intercellular lipids. [0059] It is hypothesized that the multi-chain multiple hydrophilic group-type compound expressed by formula (1) can easily align in a plane because of the bulk balance and positional relationship of the hydrophobic and hydrophilic groups, and when the multi-chain multiple hydrophilic group-type compound permeates into the horny layer of skin where the intracellular lipid lamellar structure has become disorganized, the compound can easily create the lamellar structure together with the remaining ceramide. Furthermore, the surface activity and the permeability are high, so the compound easily penetrates into the horny layer when applied to the surface of the skin. Therefore, it is thought that when the multi-chain multiple hydrophilic group-type compound expressed by formula (1) is applied to the surface of the skin, the compound permeates into the horny layer, acts in a manner similar to ceramide replacing the ceramide that was lost, and restores the barrier function of the skin. [0060] The compound expressed by formula (1) is preferably the compound expressed by the following formula (3). [0061] [C6] [0062] (In formula (3), R11 and R12 each independently represent a hydrocarbon group which may be substituted with a saturated or unsaturated substitution group of from 8 to 20 carbon atoms, R21 and R22 each independently represent either a hydrogen atom or a lower alkyl group of from 1 to 3 carbon atoms that may be substituted with a substitution group, each Y' independently represents a carboxyl group or a salt thereof, each W independently represents -O-, -S-, or -NR- (where R' represents a hydrogen atom or a hydrocarbon group of from 1 to 10 carbon atoms which may be substituted with a substitution group), and T represents a spacer of from 1 to 20 carbon atoms, j1, j2, k1, and k2 independently represent either 0, 1, or 2, but j1 and k1, and j2 and k2 cannot both be 0 at the same time.) [0063] In this case, (A) have three carboxyl groups or salts thereof as hydrophilic groups, and this is preferable because the solubility will be improved and the permeability towards skin and hair will be enhanced as compared to a conventionally known double chain double hydrophilic group-type amphipathic substance or the compound where X has a hydroxyl group as a hydrophilic group.

Examples [0100] The present invention will be described below in further detail using examples. Evaluation of the test samples for both the examples of the present invention and the comparative examples was carried out as shown below. [0101] 1. Skin Barrier Function Recovery Ratio The skin barrier recovery ratio is defined as shown below using the transepidermal water loss (TEWL (g/Hr-m2)), and evaluated based on the following criteria. The TEWL was measured using a Cutometer MPA 580 manufactured by COURAGE + KHAZAKA Electronic GMBH Corp.. (Definition of Skin Barrier Function Recovery Ratio) TEWL recovery ratio (%)=[((TEWLsds) - (TEWL over time))/((TEWLSDs) - (TEWLo))] x 100 Herein, TEWI_o,TEWLSds, and TEWL over time are defined as shown below. TEWLo: The TEWL was measured on the forearm of a panel of 5 healthy males. TE WI_o was defined as the initial average value of TEWL for the panel. TEWLsds: A 5 mass% concentration of sodium lauryl sulfate (SDS) was applied to the forearm of each panel member in order to induce a condition of reduced skin barrier function and rough dry skin, and then the TEWL value was measured. The average value for the TEWL at this time was defined as TEWLsds- This SDS process was carried out to the extent that the average value of TEWL changed from 7 g/m2hr for the healthy skin to 14 -17 g/m2hr for rough dry skin. TEWL over time: 2 uL/cm2 of test sample at an appropriate concentration was openly applied twice a day to the aforementioned rough skin, and the TEWL was measured over time for four days. The average value for the TEWL at this time was defined as TEWL over time. (Skin Barrier Function Recovery Ratio Evaluation Criteria) Skin barrier function recovery ratio is 60% or higher: ® Skin barrier function recovery ratio is 40% or higher and less than 60%: O Skin barrier function recovery ratio is 20% or higher and less than 40%: A Skin barrier function recovery ratio is less than 20%: x [0102] 2. Horny layer Condition Rough dry skin condition was induced in the same way as the evaluation for the skin barrier function recovery rate on the forearm of 5 healthy males, and then the test sample was openly applied, and the condition of the horny layer was observed four days later using a microscope (trademark, USB Microscope M2-S; manufactured by Scalar Corp.) at a zoom of 50X. The condition of the horny layer that was observed in this manner was evaluated according to the following criteria, and based on the average value of a panel of five persons, and evaluation of O was made if the average value was less than 1 point, A if the average value was 1 or higher but less than 2, and x if the average value was 2 or higher. Homy layer cells, skin ridges, skin grooves are clearly arranged: 0 points Horny layer cells, skin ridges, skin grooves are arranged: 1 points Horny layer cells, skin ridges, skin grooves are somewhat irregular: 2 points Horny layer cells, skin ridges, skin grooves are visible but irregular: 3 points Horny layer cells, skin ridges, skin grooves are blurred and irregular: 4 points [0103] 3. Human Patch Results 0.1 g of test sample was impregnated into wax paper of 1 cm2, and plastered in a covered condition on healthy skin on the forearm of a panel of 5 healthy males for 24 hours. After 24 hours, the TEWL was measured and the results of this human patch test were evaluated by the following criteria. A large increase rate in TEWL means that the sample tends to destroy the barrier function and cause rough dry skin. O: Average increasing rate of TEWL is below 10% A: Average increasing rate of TEWL is 10% or higher, but less than 30% x: Average increasing rate of TEWL is 30% or higher [0104] 4. Uniformity, Smoothness, and Stylability of Hair The test sample was thoroughly applied to a bundle of damaged hair that was prepared by the method shown below, which was then blow dried while combing. Evaluation was carried out by a panel of 10 persons from the viewpoint of "uniformity from hair roots to hair tips", "smoothness of the hair", and the "stylability of the hair". The evaluation criteria for "uniformity from hair roots to hair tips", "smoothness of the hair", and the "stylability of the hair" was as shown below. 7 or more persons gave an assessment of "good": O From 4 to 6 persons gave an assessment of "good": A 3 or less persons gave an assessment of "good": x (Method for Preparing Damaged Hair) A bundle of damaged hair was prepared by repeating 4 cycles of a process consisting of applying a permanent wave treatment, brushing 100 times, bleaching, brushing 100 times,to a bundle of healthy hair (15 cm, 1 g). [0105] 5. Hair Damage Recovery Ratio The hair damage recovery rate was defined by the following formula using damage recovered hair prepared by immersion in a test sample for 1 minute and then drying the aforementioned damaged hair. Hair damage recovery ratio (%) = tensile strength of damage recovered hair/tensile strength of healthy hair x 100 Wherein the tensile strength is defined as the breaking strength per unit cross- section area, and the breaking strength and the cross-section area of the hair are measured as shown below.
