Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair setting composition, and more particularly to a hair setting composition such as a hair setting agent, a styling agent and a hair styling agent which have both excellent set holding power and good feel. Regarding things.

[0002]

2. Description of the Related Art Hair setting agents which have hitherto been widely used are ones in which a film-forming polymer compound is dissolved in water, a lower alcohol or a mixed solvent thereof. The polymer compound blended therein has an action of fixing the hairs to each other and holding the set, but the conventionally used ones have stickiness in the process of applying to hair and drying and finishing. ,
It wasn't smooth. In order to eliminate such drawbacks, attempts have been made to improve the feel of use by adding oils and fats for cosmetics, surfactants and the like to polymer compounds. However, a hair setting agent having both a satisfactory set holding power and a feeling of use has not yet been obtained.

In recent years, a hair treatment agent containing an amphoteric polymer compound and a cationic polymer (Japanese Patent Publication No. 2-4444).
No. 6, Japanese Patent Publication No. 3-14805) and a hair treatment agent containing an amphoteric polymer compound and an anionic polymer (Japanese Patent Publication No. 3-21524) have been developed. However, these treatment agents are not satisfactory in terms of non-greasiness and smoothness after application and drying, and also because the finished hair has a stiff feel. Therefore, the adhesion between hairs is sufficient, the formed film is elastic and does not stiffen, it has excellent style retention, and it is not sticky, smooth and dull in the process of drying after application. It has been desired to develop a hair setting composition that is easy to do.

[0004]

Therefore, as a result of earnest studies, the present inventor has found that by combining hydroxyethyl cellulose with a specific amphoteric polymer, it has both excellent set holding power and good feel. It was found that a hair setting composition was obtained, and the present invention was completed.

That is, according to the present invention, the following component (A) is added in an amount of 0.05 to 10.0% by weight and the following component (B) is added in an amount of 0.05 to
It is a hair setting composition characterized by being mixed with 10.0% by weight.

(A) One or more amphoteric polymers having a molecular weight of 50,000 to 500,000, which are composed of a betaine dialkylaminoalkyl acrylate copolymer represented by the following general formula [I].

[0007]

[Chemical 3]

Wherein R ¹ and R ⁵ are hydrogen atoms or methyl groups, R ² and R ³ are alkyl groups each having 1 to 4 carbon atoms, and R ⁴ is 1 to 4 carbon atoms. Alkylene group, R ⁶ is an alkyl group or alkenyl group having 1 to 24 carbon atoms, A is an oxygen atom or NH
Each of the groups, n and m is a positive integer, and is a number such that the ratio of n: m is in the range of n: m = 2: 8 to 8: 2. )

(B) A water-soluble polymer composed of hydroxyethyl cellulose represented by the following general formula [II].

[0010]

[Chemical 4]

(In the formula, x represents a number of 100 to 500.)

As the amphoteric polymer of the component (A) used in the present invention, as described above, one or more polymers represented by the general formula [I] can be used in combination. of ^{particular, R 1, R 2, R} 3 and R ⁵ is a methyl group, an amphoteric polymer R ⁴ is a methylene group, a is an oxygen atom are preferred, and those wherein R ⁶ is a stearyl group. among these, R ⁶ When used in combination with one having 1 to 4 carbon atoms, particularly excellent setting force and smoothness can be obtained. The molecular weight is 50,000 to 500,000. n and m are positive integers, respectively, and the ratio of n: m is
The range is n: m = 2: 8 to 8: 2. When the ratio of m to n exceeds n: m = 2: 8, there is a problem in solubility in alcohol and water, and the washability of hair deteriorates. Furthermore, there is a problem in terms of affinity with hair, and flaking becomes easy. On the other hand, the ratio of m to n is n: m
When it is smaller than 8: 2, the film forming power is poor and there is a problem in the setting power. Furthermore, the hygroscopicity is increased and stickiness occurs. The amphoteric polymer is 0.05 in the total composition.
-10.0 wt%, preferably 0.2-5.0 wt%. If it is less than 0.05% by weight, the effect as a setting agent cannot be obtained, and if it exceeds 10.0% by weight, a large amount is added to the hair, which causes problems in washing hair and is not preferable. Examples of the amphoteric polymer of the present invention include Yukaformer AM75-SM and Yukaformer AM75-R-2.
05S (all are trade names manufactured by Mitsubishi Kasei Co., Ltd.) and the like.

The water-soluble polymer as the component (B) is hydroxyethyl cellulose represented by the above-mentioned general formula [II], which is contained in an amount of 0.05 to 10.0% by weight, preferably 0.5. ~ 5.0 wt% is compounded. If it is less than 0.05% by weight, the effect of smoothness cannot be obtained, and if it exceeds 10.0% by weight, flaking may occur.

The compounding ratio of the amphoteric polymer and hydroxyethyl cellulose is preferably 30: 1 to 1: 2, more preferably 20: 1 to 3: 5.
