Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hair cosmetic, and more particularly to a hair cosmetic which imparts firmness and stiffness, has excellent shampooing resistance, has good adaptability to the hair, and has an improved use feeling and gloss of the hair. And hair cosmetics.
The hair cosmetic of the present invention is applied to a conditioner at the time of perm treatment, an auxiliary for a hair setting agent, a mousse agent, a blow lotion, and the like.

[0002]

2. Description of the Related Art Hair cosmetics are broadly classified into hair washing cosmetics such as shampoos and rinses, and hair finishing cosmetics such as hair mousses, hair liquids and pomades. Efforts have been made to provide cosmetics and hair cosmetics having a concept outside of these two categories.

[0003] Among these attempts, the provision of a hair cosmetic that imparts firmness and firmness to the hair is becoming weaker, especially in recent stressful societies, because the function of the hair root, which is the basis of the hair, is becoming weaker. Because I can not deny that
Extremely significant.

[0004]

However, at present, means for imparting firmness and firmness to hair has not yet been provided. That is, for example,
Even if stiffness can be given, there is a problem that the hair returns to its original state after shampooing due to insufficient shampoo resistance.

The present invention has been made in view of the above circumstances, and provides hair with firmness and stiffness, has excellent shampoo resistance, has good adaptability to hair, and can provide improved use feeling and gloss of hair. It is intended to provide a hair cosmetic.

[0006]

The inventors of the present invention have conducted intensive studies and as a result, have found that polyamide epichlorohydrin resin, which is used as a shrink-preventing agent in wool processing or a film-forming agent for cosmetics, and a nonionic silicone and / or nonionic silicone. Alternatively, they have found that the above problem can be solved by combining with a surfactant, and based on this, the present invention has been completed.

That is, the present invention relates to a hair cosmetic comprising a polyamide epichlorohydrin resin and a nonionic silicone and / or a nonionic surfactant.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

The polyamide epichlorohydrin resin used in the present invention is a resin obtained by adding and condensing a polyamide comprising adipic acid and diethyltriamine and epichlorohydrin. Polyamide epichlorohydrin resin is used as a shrinkproofing agent in wool processing, and is used as a film-forming agent in the cosmetics field. The molecular weight of the polyamide epichlorohydrin resin is generally 1000 to 5

EXAMPLES The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the invention is limited thereto. In addition, the compounding amount is weight%.

I. Pure bending strength of hair (Bending rigidity (= B
Value)) In order to evaluate the pure bending strength of the hair of the hair cosmetic composition of the present invention, the B value was determined by the following method.

(1) Method of measuring B value A hair stiffness tester (KES-FB2
-S: manufactured by Kato Tech Co., Ltd.) The hair was placed on a fixed chuck and a movable chuck without loosening the hair, and both ends of each hair were fixed. Then set the sample size to 3c
m and the measurement was performed. In general, when one of the elastic bodies is fixed and bent at a constant speed, the degree of bending is proportional to the curvature.

[0033]

A relational expression of M = Bk (M: force required for bending, B: bending rigidity, k: curvature) is established.

The proportionality constant B (B value) was used as an index of the firmness and firmness of the hair. That is, if the B value is large, it can be evaluated that hair has firmness and firmness. Conversely, if the hair is small, it is evaluated that the hair has lost its firmness.

(2) Preparation of Sample (Sample 1) "Polaramine E-125" (manufactured by Toho Chemical Co., Ltd.) 40 (containing 12.5% by weight of polyamide epichlorohydrin resin) (effective component 5% by weight) Ethanol 20 Ethyl paraben 0. 1 "Silicone SC1014M" (Shin-Etsu Chemical Co., Ltd.) 0.5 Purified water residue (Sample 2) "Polaramine E-125" (Toho Chemical Co., Ltd.) 40 (containing 12.5% by weight of polyamide epichlorohydrin resin) ( Ethanol 20 Ethylparaben 0.1 "Emarex 520-P" (manufactured by Nippon Emulsion Co., Ltd.) 0.5 Purified water residue (3) Examination of imparting film properties to hair Sample 1, The rate of change of the B value according to the number of times the hair to which Sample 2 was applied was repeatedly bent was measured. The results are shown in FIG.

In FIG. 1, the ordinate represents the rate of change of the B value, the abscissa represents the number of measurements of the B value (corresponding to the number of repeated bendings), black circles represent sample 1, black diamonds represent sample 2, and white triangles represent samples. Indicates no application. As is clear from FIG.
Since the rate of change of the B value in the zero-time repeated bending was almost the same as that of the non-coated one, it can be seen that the films formed by both samples have extremely high plasticity.

(4) Investigation of firmness and shampoo resistance to hair For samples 1 and 2, the change rate of the B value when drying and wetting were repeated was determined, and the firmness and stiffness of hair by these samples were determined. Was examined.

Further, after treatment with a shampoo, washing with water, drying treatment, and then wetting again,
The rate of change of the B value when the drying treatment was performed again was determined.

The drying treatment was carried out by drying the hair at 50 ° C. for one hour, and the wetting treatment was carried out by immersing the hair sample in purified water for one hour.

FIG. 2 shows the results. In the figure, the horizontal axis indicates the rate of change of the B value.

As shown in FIG. 2, with respect to Sample 1, the B value after drying was about 2.6 times that before coating and about 1.2 to 1.4 times that after coating even after shampooing. For sample 2, the B value after drying was about 3 times that before coating and 1.2 to 1.5 times after shampooing before coating. From these facts, it can be seen that both Samples 1 and 2 give hair firmness and stiffness, show stiffness after shampooing, and have excellent shampoo resistance.
