[Industrial application field]

TECHNICAL FIELD The present invention relates to a type of hair cosmetic that is washed away after use, such as shampoo or conditioner. [0002]

[Prior Art and Problems to be Solved by the Invention] Hair cosmetics include leave-on types such as hair styling products and blow-drying agents, and rinse-on types such as shampoos and conditioners. off) type. Among these, wash-off type hair cosmetics such as shampoos and conditioners are intended to keep hair beautiful by cleaning dirt from the hair and replenishing excessively degreased oil. In order to achieve this effect, it has been proposed to incorporate various additive ingredients into such wash-off type hair cosmetics. [0003] As one of these additive components, a water-soluble polymeric substance such as a cationic acrylamide copolymer, a polyacrylic acid copolymer, an amphoteric polymeric substance such as an amphoteric compound of 1-polyacrylic acid amide, etc. is blended. It is known to do. [0004] However, even if the above-mentioned water-soluble polymer substances are incorporated into washable type hair cosmetics, there is a problem that the effects are not fully exhibited because these water-soluble polymer substances are washed away after use. be. [0005] The present invention was made in view of the above circumstances, and an object of the present invention is to provide a rinse-off type hair cosmetic that effectively exhibits the excellent effects of the water-soluble polymer substance described above. [0006]

[Means and Effects for Solving the Problems] As a result of intensive studies to achieve the above object, the present inventor has discovered that certain water-soluble polymer substances such as cationic polymer substances, anionic polymer substances, and amphoteric polymer substances Glucose and/or fatty acid esters of alkyl glucosides with alkyl groups having 1 to 4 carbon atoms (
(hereinafter collectively referred to as glucose fatty acid esters), especially glucose fatty acid esters with a monoester content of 90% or more, surprisingly, the excellent effects of each of the water-soluble polymer substances mentioned above, such as adding luster to the hair. It has been found that this product has the effect of imparting elasticity and elasticity to the hair, the effect of imparting moisture to the hair, etc., and that these effects can be imparted to the hair even if it is rinsed with water after use. This led to the invention. [0007] Accordingly, the present invention provides a type of hair cosmetic that contains a specific water-soluble polymeric substance and glucose fatty acid ester and is rinsed off after use. [0008] Hereinafter, the present invention will be explained in more detail. Specific water-soluble polymer substances used in the present invention include cationic polymer substances for imparting shine to hair, and imparting elasticity and body to hair. Examples include anionic polymeric substances and amphoteric polymeric substances. Specifically, the water-soluble polymer substances listed below may be used alone or in combination of two or more. [0009] (1) Cationic water-soluble polymeric substance other than cationized cellulose A. Vinylpyrrolidone/dialkylamino(meth)acrylate copolymer Gafquat 7 manufactured by Gaf Corporation
Commercially available products such as No. 34,755 can be used. Commercial products such as dimethyldiallylammonium chloride homo- and copolymer Merquat 100, 550 manufactured by Merck & Co., Ltd. can be used. C. Dipropylene triamine condensate B. Quaternized ammonium derivative of collagen protein hydrolyzate Naturally obtained collagen protein with an average molecular weight of 20
Particularly preferred are those which are hydrolyzed to a molecular weight of 0 to 8,000 and then converted into a quaternized ammonium derivative using a general method. E. As other cationic polymers, JP-A-58-
Those described in Japanese Patent No. 124712 can be used. [0010] (2) Anionic water-soluble polymer substance (a), polyacrylic acid copolymer (b), acylated product of collagen protein hydrolyzate, alkali metal salt or hydroxyalkyl-substituted ammonium salt of the acylated product, starting material collagen The protein hydrolyzate preferably has an average molecular weight of 200 to 8,000, and the acylating agent preferably has a carbon number of 6 to 24. Particularly preferred are N-cocoyl polypeptide, N-oleyl polypeptide, N-undecyl polypeptide, and their alkali metal salts and hydroxyalkyl-substituted ammonium salts. [0011] (3) Amphoteric water-soluble polymeric substance A, a vinyl monomer having a C0OH group such as (meth)acrylic acid, maleic acid, α-chloroacrylic acid, dialkylaminoalkyl (meth)acrylate, dialkylaminoalkyl (meth)acrylate, etc. Copolymers with vinyl basic monomers containing basic nitrogen atoms, such as meth)acrylates. Examples of such copolymers include those described in US Pat. No. 3,836,537. (b) Homopolymers and copolymers consisting of vinyl monomers having a carboxybetaine group (c) Polymers having an average molecular weight of 2 to 1 million represented by the following formula [■] [0012]

[Formula 1] (wherein R1 and R8 are each a hydrogen atom or a methyl group,
R2 is an alkyl group having 1 to 18 carbon atoms, R4 and R6 are each an alkylene group having 1 to 4 carbon atoms, R2i is a hydrogen atom, a methyl group or an ethyl group, and P/Q is a molar ratio of l/9.
~8/2. ) D. Collagen protein hydrolyzate having an average molecular weight of 200 to 8,000 is particularly preferred. [0013] The amount of the water-soluble polymer substance to be blended is appropriately selected depending on the type thereof and the properties imparted to the hair. For example, collagen protein hydrolyzate and its derivatives are blended to give hair a moisturized feel, elasticity, and stiffness, and the blending amount is preferably 0.05 to 20% by weight of the total hair cosmetic. It is 0.1 to 10% by weight. If it is less than 0.005% by weight, the desired effect will not be sufficiently imparted, and if it exceeds 20% by weight, the hair will tend to become sticky even when dried after use. [0014] On the other hand, the glucose fatty acid esters (fatty acid esters of glucose and/or alkyl glucosides in which the alkyl group has 1 to 4 carbon atoms) used in the present invention include glucose or alkyl glucosides and 6 to 20 carbon atoms. More preferably, those obtained from 6 to 12 fatty acids or fatty acid derivatives such as lower alkyl esters thereof are suitable. [0015] In this case, as the raw material glucose, it is possible to use starch obtained by hydrolyzing starch such as corn or potato with an acid or an enzyme, and then decolorizing and purifying the starch. Examples of such substances include crystalline glucose, powdered glucose, and granular glucose defined by JAS. [0016] Further, as the alkyl glucoside in which the alkyl group of the raw material has 1 to 4 carbon atoms, the above-mentioned glucose is added with a fatty acid alcohol having 1 to 4 carbon atoms, such as 1-methyl glucoside, 1-ethyl glucoside, 1-ethyl glucoside, -Butyl glucoside is exemplified, and commercially available products made from stearic acid are representative examples. [0017] On the other hand, fatty acids having 6 to 20 carbon atoms can be suitably used, regardless of whether they are natural 2-synthesized, saturated, unsaturated, straight chain 2-branched, single, mixed, etc. Octanoic acid, decanoic acid, lauric acid, myristic acid, palmitic acid, which are obtained by hydrolyzing vegetable oils such as coconut oil, palm oil, tallow oil, rapeseed oil, and soybean oil, and animal oils as fatty acids.
Examples include saturated and unsaturated linear fatty acids such as stearic acid, linoleic acid, oleic acid, and undecanoic acid. Also,
As synthetic fatty acids, mixtures of linear and branched fatty acids obtained by oxidizing olefin polymers can be used, and fatty acids derived from microorganisms such as γ-lylunic acid can also be used. can. Further, as the lower ester of the fatty acid, an alkyl ester having 1 to 8 carbon atoms such as methyl, ethyl, and propyl of the above-mentioned fatty acids can be used, and a halogenated fatty acid can also be used as the raw material. [0018] Glucose fatty acid esters can be produced by ester synthesis using these raw materials using lipase or the like, such as transesterification between raw material oil and glucose, transesterification between lower alcohol esters of fatty acids and glucose, and transesterification between fatty acids and glucose. Synthesis is preferably carried out by methods such as ester synthesis using a fatty acid chloride and glucose, and various other known methods. [0019] In this case, in the present invention, the glucose fatty acid ester has a monoester content of 90% or more, particularly 95% or more.
% or more of glucose fatty acid ester is preferable in order to achieve the above-mentioned object of the present invention. Further, the polyester content of triester or higher is 1% or less, especially 0.
It is more preferable that the content is 5% or less, but since the above-mentioned known methods all have a low monoester content and produce esters with a high tri- or higher polyester content, when obtaining a monoester, fractionation after synthesis is necessary. , isolation may be laborious. Therefore, in this respect, the method using heat-stable lipase, which was previously proposed by the present applicant in Japanese Patent Application No. 1-210495, is preferably adopted for the production of monoester. [00201] The glucose fatty acid monoesters are those of the following formula in which the OH group at the 6-position of glucose is esterified. [0021]

[Chemical formula 2] (However, R-C- is a fatty acid residue having 2 to 22 carbon atoms, R
o represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. ) [0022] Such glucose fatty acid monoester includes 6
-0-octanoylglucose, 6-○-decanoylglucose, 6-○-lauroylglucose, 6-0-myristoylglucose, 6-0-valmitoylglucose, 6-0-oleoylglucose, 6-0- Examples include lil'oyl glucose. [0023] In addition, examples of the alkyl glucoside fatty acid ester having 1 to 4 carbon atoms include methyl 6-0-octanoyl glucoside, ethyl 6,-0-octanoyl glucoside, and ethyl 6-0-octanoyl glucoside.
Examples include -0-lauroyl glucoside, butyl 6-0-octanoyl glucoside, ethyl 6-0-balmitoyl glucoside, and ethyl 6-0-oleoyl glucoside. [0024] The present invention also provides one of the above glucose fatty acid esters.
A species may be used alone or two or more species may be used in combination. [0025] The blending amount of glucose fatty acid esters can be selected from various values, and is usually 1 to 20% by weight of the total hair cosmetic composition. [0026] The rinse-off type hair cosmetic of the present invention includes shampoo,
It can be prepared as a rinse, etc., and contains commonly used ingredients depending on its type, such as anionic, nonionic, amphoteric, cationic surfactants, oils, higher alcohols, polyols, anti-inflammatory agents, anti-dandruff agents, Flavors, pigments, preservatives, etc. can be added. In particular, it is preferable to add various nonionic polymer compounds such as polyethylene glycol and polyacrylic acid ester for dispersion stabilization. [0027]
