JP5553192B2 - Hair cosmetics that do not wash away - Google Patents

Description

  The present invention relates to hair cosmetics that do not wash away (particularly treatments that do not wash away).

  As hair cosmetics that are not washed away, those in which silicone is blended for the purpose of imparting a slipperiness to the hair are known.

  However, since silicone has build-up properties (that is, accumulation on the hair surface), repeated use of silicone-containing hair cosmetics gradually causes hair to become stiff and itchy and difficult to blow. was there. In addition, when chemical hair treatment (wavebing, coloring, etc.) is performed, there is a problem that it is difficult for a drug (wave agent, hair dye, etc.) to penetrate into the hair.

  In order to solve these problems, Patent Document 1 proposes a “silicone-like feel-imparting agent” as a silicone substitute.

JP-A-2005-306786.

  However, the silicone-like feel-imparting agent can sufficiently impart a touch similar to silicone in a hair cosmetic to be washed away, but cannot be imparted sufficiently in a hair cosmetic that is not washed away.

  In view of the above circumstances, the present invention can impart slip and the like without using silicone, and as a result, can be easily blown, and can also impart other touches (harshness, moist feeling, clumping, etc.), and is not washed away. The purpose is to provide cosmetics.

  In order to achieve the above object, the inventors of the present application diligently studied, and as a result, they found that if cationized honey and hydroxyethyl chitosan were used in combination, the present invention was achieved.

That is, the present invention provides a non-washing-out hair cosmetic characterized by containing 0.005 to 0.5 % by weight of cationized honey and 0.00002 to 0.0006% by weight of hydroxyethyl chitosan. .

  According to the present invention, there is provided a hair cosmetic that does not wash away, which can impart slipping or the like to the hair without using silicone, and as a result, can be easily blown, and can also impart other touches (harshness, moist feeling, clumping, etc.). Can be provided.

Hereinafter, this invention is explained in full detail based on embodiment.
The non-washing hair cosmetic of the present invention contains cationized honey. Cationized honey is a substance having a structure in which a cationic functional group is introduced into honey, and examples thereof include “hydroxypropyltrim honey” described in International Cosmetic Ingredient Dictionary and Handbook.

  The hair cosmetic composition that does not wash away according to the present invention contains hydroxyethyl chitosan. Of the water-soluble chitosans, only hydroxyethyl chitosan specifically expresses the same feel as silicone when used in combination with cationized honey, and does not appear in other water-soluble chitosans (for example, hydroxypropyl chitosan).

  The hair cosmetic composition that is not washed off according to the present invention may contain an additive as long as the effects of the present invention are not impaired. Examples of the additive include one or more of a surfactant, an oil component, and a polyhydric alcohol.

  In the additive, surfactants include cationic surfactants [lauryltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, distearyldimethylammonium chloride, their corresponding bromides, ethyl lanolin sulfate fatty acid Aminopropylethyldimethylammonium dirapeseed seed oil fatty acid ethyl hydroxyethylmonium methosulfate, dicocoylethylhydroxyethylmonium methosulfate, etc.], amphoteric surfactant [carboxylic acid type betaine (stearic acid dimethylaminoacetic acid betaine, coconut oil fatty acid amidopropyl) Dimethylaminoacetic acid betaine, lauric acid amidopropyl betaine, coconut oil fatty acid amidopropyl betaine, lauryl di Thiolaminoacetic acid betaine)], nonionic surfactants [POE alkyl ethers {POE cetyl ether, POE stearyl ether, POE lauryl ether, POE isostearyl ether, POE octyldodecyl ether, etc.}, POE • POP alkyl ethers {POE • POP cetyl ether, POE · POP decyl tetradecyl ether, POE · POP butyl ether, etc.}, (poly) glycerin fatty acid ester, sorbitan fatty acid ester, POE (hardened) castor oil, sucrose fatty acid ester, alkyldimethylamine oxide, etc.] One or more of these may be contained.

One or more of these may be contained.

  Examples of the ester oil in the oil component of the additive include, specifically, monohydric alcohol esters of fatty acids, polyhydric alcohol esters of fatty acids, monoesters of polybasic acids, polyesters of polybasic acids (including diesters), and the like. Glyceryl tri-2-ethylhexanoate, neopentyl glycol dicaprate, dicaprylyl ether, phytosteryl oleate, di (phytosteryl octyldodecyl) lauroylglutamate, propylene glycol di (capryl / caprate), propylene glycol dicaprylate, tri ( (Capryle capric acid) glyceryl, isopropyl myristate, isopropyl palmitate, octyldodecyl myristate, hexyldecyl isostearate, pentaerythrityl tetra-2-ethylhexanoate, succinic acid 2-ethylhexyl, diethoxyethyl succinate, diisopropyl adipate, diisobutyl adipate, diethyl sebacate, diisostearyl malate, lanolin fatty octyldodecyl and the like, may contain these one or more.

  Examples of silicones in the oil component of the additive include dimethylpolysiloxane, methylcyclopolysiloxane, methylphenylpolysiloxane, highly polymerized methylpolysiloxane, decamethylcyclopentasiloxane, amodimethicone, aminopropyldimethicone, aminoethylaminopropylmethicone / Dimethicone copolymer, dimethylsiloxane / methyl (aminopropyl) siloxane copolymer, cross-linked silicone [dimethicone crosspolymer, (dimethicone / vinyl dimethicone) crosspolymer, etc.] may be mentioned, and one or more of these may be contained.

  In the oil component of the additive, vegetable oils include rice bran, olive oil, castor oil, avocado oil, sunflower oil, safflower oil, wheat germ oil, macadamia nut oil, grape seed oil, rosehip oil, palm oil, palm kernel oil, Jojoba oil, hydrogenated palm oil, hydrogenated soybean oil, hydrogenated rapeseed oil, avocado oil, macadamia nut oil, coconut oil, shea butter, lanolin and the like may be included.

  Examples of hydrocarbons in the oil component of the additive include (light iso) paraffin, microcrystalline wax, petrolatum, ceresin, (synthetic) squalane, (partially hydrogenated) squalene, synthetic hydrocarbon wax, ozokerite, pristane, and the like. One or more of these may be contained.

Examples of the polyhydric alcohol in the additive include propylene glycol, 1,3-butylene glycol, 3-methyl-1,3-butanediol, ethoxydiglycol, dipropylene glycol, glycerin, diethylene glycol monoethyl ether, and the like. One or more of these may be contained.

  As the other additives, a preservative, a pH adjuster, a fragrance and the like may be added to the non-washed hair cosmetic of the present invention.

In the composition of the hair cosmetic composition according to the present invention, the cationized honey is 0.005 to 0.5 (preferably 0.015 to 0.15) weight, and the hydroxyethyl chitosan is 0.00002 to 0.0006 ( Preferably, 0.00005 to 0.0006)% by weight. Moreover, in an additive, surfactant is 0.01-5.0 (especially 0.1-3.0) weight%, and an oil-based component is 0.01-20.0 (especially 0.1-10.0). The weight percent and the polyhydric alcohol are preferably 0.01 to 10.0 (particularly 0.05 to 3.0) weight percent, respectively.

If the amount of cationized honey or hydroxyethyl chitosan is too small, hair slippage and other feelings (harshness, moistness, clumping, etc.) may not be exhibited. On the other hand, if the amount of cationized honey is too large, the hair may be stiff, poorly packed, reduced in slipping, and the like. If there is too much hydroxyethyl chitosan, the moist feeling may be reduced, sticky, or caught.

Examples of the “hair cosmetic” in the non-washed hair cosmetic of the present invention include, for example, tri Treatment, hair water, hair oil, hair cream, hair wax, hair gel, hair milk, hair foam and the like. Preferably, the hair cosmetic that does not wash away is a treatment that does not wash away.
