Abstract

PURPOSE: To obtain a hair cosmetic having excellent color fading-preventive effect on dyed hair, excellent in use feeling and finished feeling by containing polyphenols, a cationic surfactant and/or a nonionic surfactant and a higher alcohol. CONSTITUTION: This cosmetic contains a suitable amount of polyphenols, 0.5-10wt.% cationic surfactant (e.g. stearyl trimethylammonium chloride) and/or 0.1-5wt.% of a nonionic surfactant (e.g. a polyoxyethylene alkylether) and 1-10wt.% of a 14-22C higher alcohol (e.g. cetyl alcohol) as active components. In the case the polyphenols are hydrolyzable tannins and/or a hydrolyzable tannic acid, its content is 0.01-1wt.%. Further, a cationic polymer, an ultraviolet ray absorber and usual optional components are mixed to prepare a shampoo, a rinse, a treatment or a hair cosmetic, etc. The cosmetic is readily usable and having excellent finished feeling because of its suitable viscosity.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for hair which has an excellent effect of preventing discoloration of dyed hair, has an appropriate viscosity, and is excellent in the feeling of use and finish.

[0002]

2. Description of the Related Art Color retention is one of the recent demands for hair dyes from consumers. This phenomenon is caused by discoloration due to the structural change of the oxidation dye or acid dye and the loss of the dye from the hair.

Conventionally, as disclosed in JP-A-61-218512 and JP-A-4-360817,
The components in the hair dye composition are prepared in order to improve the fastness, but the effect is not sufficiently satisfactory,
Further, the after-care agent after hair dyeing as disclosed in JP-A-6-92824 is not sufficiently satisfactory in the effect of preventing fading.

[0004]

DISCLOSURE OF THE INVENTION The inventors of the present invention have conducted extensive studies as an improvement of the above-mentioned drawbacks of the prior art, and as a result, an appropriate amount of polyphenols was added in an amount of 0.5 to 1 in hair cosmetics.
Cationic surfactant and / or 0.1 containing 0% by weight
When mixed with a nonionic surfactant contained in an amount of up to 5% by weight and a higher alcohol having a carbon number of 14 to 22 contained in an amount of 1 to 10% by weight, it has an excellent anti-fading effect on dyed hair and is suitable. It has been found that a cosmetic for hair that is easy to use and has an excellent finished feeling can be obtained because of its high viscosity, and completed the present invention.

[0005]

[Means for Solving the Problems] That is, claim 1 of the present invention provides polyphenols and a cationic surfactant 0.5.
-10 wt% and / or nonionic surfactant 0.1-
5% by weight, higher alcohols having 14 to 22 carbon atoms 1 to 10
It is a cosmetic for hair containing 100% by weight.

A second aspect of the present invention is the cosmetic for hair according to the first aspect, which contains a cationic polymer.

Furthermore, claim 3 of the present invention is characterized in that the hydrolyzable tannins and / or polyphenols which are hydrolyzable tannic acid are contained in an amount of 0.01 to 1% by weight. For cosmetics.

Further, claim 4 of the present invention is the cosmetic for hair according to any one of claims 1, 2 and 3 which contains an ultraviolet absorber.

The polyphenols in the present invention include gallotanninic acid, keburinic acid, hamamelitannin, asertannin, gallic acid, m-digallic acid, dehydrodigallic acid, valonic acid, kebouric acid, hexahydroxydiphenic acid, ellagic acid. , Caffeic acid, p-coumaric acid, ferulic acid, sinapinic acid, chlorogenic acid and the like.

As the cationic surfactant in the present invention, alkyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, stearyl trimethyl ammonium bromide, cetostearyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, behenyl bromide. Trimethylammonium and the like are included, and these are 0.5% by weight to 10% by weight in the cosmetic for hair. If the blending amount is less than 0.5% by weight, the effect of the present invention is not exhibited, and if it exceeds 10% by weight, the hair becomes sticky and gives a heavy finish feeling.

Examples of the nonionic surfactant in the present invention include polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether and the like, which are contained in the hair cosmetic in an amount of 0.1% to 5% by weight. Is. If the blending amount is less than 0.1% by weight, the stability of the cosmetic for hair is problematic, and if it exceeds 5% by weight, the hair becomes sticky and a heavy finish feeling is produced.

The higher alcohol in the present invention includes
Examples thereof include lauryl alcohol, cetyl alcohol, stearyl alcohol, aralkyl alcohol and behenyl alcohol, and these are 1 to 10% by weight in the cosmetic for hair. If the amount is less than 1% by weight, the viscosity is too low, and if it exceeds 10% by weight, the viscosity is too high.
There is a problem in usage.

Examples of the cationic polymer in the present invention include cationized cellulose, cationized guar gum, diallyl quaternary ammonium salt polymer, diallyl quaternary ammonium salt / acrylamide copolymer, and quaternized polyvinylpyrrolidone. These are preferably 0.001 to 1% by weight in the hair cosmetic composition.

Examples of the ultraviolet absorber in the present invention include benzophenones, cinnamic acids, para-aminobenzoic acids, salicylic acids, benzotriazoles and the like, and the blending amount thereof is not particularly limited, but is 0.01% by weight to 3%.
Weight percent is preferred.

If desired, the hair cosmetic composition of the present invention may be a component commonly used in hair cosmetic compositions, such as a lanolin derivative, a protein derivative, a silicone oil such as methylpolysiloxane or methylphenylpolysiloxane, or polyethylene glycol.
