Abstract

PURPOSE:To provide a hair treatment excellent in transparency and stability with time and having a uniform conditioning effect on the hair. CONSTITUTION:This hair treatment contains a cationized guar gum synthesized by introducing a quaternized nitrogen-containing group into guar gum and another cationic polymer, e.g. a cationized cellulose derivative or a copolymer of a diallyl quaternary ammonium salt and acrylamide preferably in a ratio of 4:1 to 1:4.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hair treatment agent which is stable over time and which can evenly impart a conditioning effect to hair. For example, when used as a shampoo, it can be used as a finger when washing hair and when rinsing. Excellent in smoothness of hair,
The present invention relates to a hair treatment agent which is non-greasy, has a smooth finish, has an appropriate viscosity, and is excellent in transparency.

[0002]

2. Description of the Related Art In recent years, cationized guar gum has come to be used as a polymer having excellent conditioning properties for hair and excellent thickening properties. Conventionally, it has been known that when a cationized guar gum is blended in a shampoo, a shampoo composition which is excellent in finger passage when washing hair, has no squeak of hair when rinsed, gives a smooth feel, and gives a finish without stickiness is obtained. ing.

[0003]

However, when the cationized guar gum is blended in such an amount that an effect can be obtained to some extent, the aqueous solution thereof lacks transparency and precipitates over time. In addition, there is a problem in that the viscosity becomes too high and gel or jelly is formed, which is not preferable in use.

In a hair treatment composition containing a cationized guar gum, the fact that it is unstable with time means that not only a uniform conditioning effect cannot be obtained, but also
Not desirable as a product. In the case of a transparent preparation, the opacity of the aqueous solution of the cationized guar gum is vague and cloudy, which has the drawbacks of impairing aesthetics and reducing the commercial value, which has been a major problem in formulating.

[0005]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that conditioning by combining cationized guar gum with one or more other cationic polymers. It has been found that the effect is not lowered, the occurrence of precipitation is suppressed, and the transparency of the aqueous solution is increased.

In some cases, by using a polyhydric alcohol in combination with a combination of cationized guar gum and one or more other cationic polymers, the effect is enhanced and an excellent hair treatment agent can be obtained. I found it. In addition, a combination of cationized guar gum and one or more other cationic polymers, and an anionic surfactant and an amphoteric surfactant are blended with the guar gum to smooth the fingers when washing the hair and smoothing the hair when rinsing. , The feeling of finish is significantly improved compared to the case where the cationized guar gum is used alone,
Moreover, they have found that a hair treatment agent having an appropriate viscosity and excellent transparency can be obtained, and have completed the present invention.

That is, the present invention includes the following inventions. (1) Cationized guar gum and other cationic polymers 1
A hair treatment agent containing at least one species. (2) The hair treatment agent according to (1) above, which further contains a polyhydric alcohol. (3) The hair treatment agent according to (1) above, which further contains an anionic surfactant and an amphoteric surfactant.

Hereinafter, the hair treatment agents described in (1), (2) and (3) above will be collectively referred to as the hair treatment agent of the present invention. The hair treatment agent in the present invention may be any agent as long as it treats hair, and specific examples of use include shampoo, conditioner, pomade, hair cream, hair liquid and blow. Examples include lotions and setting gels.

The cationized guar gum in the present invention is generally a guar gum (generic name: galactomannan) into which a group containing a quaternized nitrogen is introduced. In detail,
Guar gum is produced by mechanically crushing the endosperm section of the legume crop guar, and is a polysaccharide having β-1,4-glucoside bonds. The cationized guar gum introduces a group containing a quaternized nitrogen atom such as 2,3-epoxypropyltrimethylammonium chloride, glycidyltrimethylammonium chloride, 3-chloro-2-hydroxypropyltrimethylammonium chloride, which is a cationizing agent, into the guar gum. It is obtained by Specific examples thereof include Jaguar C-17, Jaguar C-16, Jaguar C-13-S (Celanese Company) and the like.

The cationized guar gum in the present invention preferably has a nitrogen content of 0.8 to 3.0%,
More preferably, the nitrogen content is 1.0 to 2.5%. When the nitrogen content of the cationized guar gum is less than 0.8%, the adsorptivity to hair is reduced and the conditioning effect is insufficient. When the nitrogen content of the cationized guar gum exceeds 3.0%, the adsorptivity to hair is too large, which is not preferable as a product.

The nitrogen content in this specification means
It means the value measured by the second method shown in the method for quantifying nitrogen based on cosmetic raw materials (method in which an organic substance containing nitrogen is converted to ammonium sulfate with sulfuric acid and the amount of ammonia is measured). Further, the mixing ratio of the cationized guar gum to the total composition of the hair treatment agent of the present invention is important when considering the transparency of the aqueous solution and the conditioning effect, and is 0.05% in the total composition of the hair treatment agent of the present invention. It is preferable to blend in an amount of up to 3.0% by weight, particularly preferably 0.1 to 1.0% by weight. If the blending ratio is less than 0.05% by weight, the conditioning effect on the hair will be weak, and if it exceeds 3.0% by weight, adsorption to the hair will be too much, and it will cause stiffness during use, which is not preferable.

The other cationic polymer in the present invention may be any cationic polymer other than the cationized guar gum, but is particularly a copolymer of cationized cellulose derivative, diallyl quaternary ammonium salt and acrylamide. (Copolymer), one or more cationic polymer compounds selected from quaternized polyvinylpyrrolidone derivatives and polyglycolamine condensates are preferable.

The cationized cellulose derivative is generally obtained by introducing a group containing a quaternized nitrogen such as hydroxypropyltrimethylammonium chloride or dimethyldiallylammonium chloride into cellulose or hydroxyalkylcellulose having a hydroxyalkyl group introduced therein.
