Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, and more specifically, it imparts excellent gloss to the hair, provides a smooth feel to the hair, and has good set holding power. The present invention relates to a hair cosmetic composition capable of adhering and restoring the split ends of the hair.

[0002]

Conventionally, hair cosmetics have been used in hair cosmetics for the purpose of imparting gloss and smoothness to hair, such as silicone oil, high molecular weight dimethyl polysiloxane, high molecular weight methylphenyl polysiloxane, and ester. Oils such as oils and hydrocarbon oils are used after being solubilized, emulsified and dissolved. In particular, silicone oil has a low surface tension, is excellent in hair familiarity, and has a good gloss, and has been widely used in recent years. However, there is a limit to the amount of oil, so if you use it in large amounts or if consumers use it for a long time,
There was a drawback that the hair became greasy. Further, although a cation activator is often used for the purpose of imparting smoothness, it has a drawback that it does not give a sufficiently satisfactory gloss, and that a large amount of it is not preferable in terms of safety.

[0003] In general, hair is significantly damaged and deteriorated by frequently repeating hair washing, brushing, heat with a drier, hair coloring, and beauty treatment with a bleaching agent, and as a result, it dries and becomes dry and split ends, Broken hair,
It is well known that hair loss is increased and strength is reduced.

On the other hand, the hair setting agents which have been widely used in the past are those 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.

More recently, for the purpose of coating the split ends of hair, a hair cosmetic composition has been developed in which one kind of polysiloxane-oxyalkylene copolymer is used in combination with a silicone derivative. Has been reported to be excellent and to have excellent adhesion to split ends (Japanese Patent Laid-Open No. 6-157247). However, even with this method, although the feel was good, the set holding power was still incomplete.

Therefore, the fixing force between the hairs is sufficient,
It has been desired to develop a hair cosmetic having a formed film that is rich in elasticity and does not become stiff, has an excellent style-retaining power, and is non-greasy, smooth, and easy to apply in the process of drying after application. .

[0008]

Under such circumstances, the inventors of the present invention have conducted extensive studies and as a result, as a result, a specific polysiloxane-oxyalkylene copolymer and a specific vinylpyrrolidone / dimethylaminoethyl methacrylate diethyl sulfate salt It was found that a hair cosmetic having both excellent set-holding power and good feel can be obtained by blending with a polymer, and the present invention has been completed.

That is, the present invention is a hair cosmetic containing the following components (A) and (B).

(A) One or more polysiloxane-oxyalkylene copolymers represented by the general formula (1).

= 3: 7 to 7: 3. The ratio of y to x is x: y
= 2: 8, there is a problem in solubility in alcohol and water, and the hair washability is deteriorated. Furthermore, there is a problem in terms of affinity with hair, and flaking becomes easy. On the other hand, when the ratio of y to x is smaller than x: y = 8: 2, the film forming force is poor and there is a problem in the setting force. Furthermore, the hygroscopicity is increased and stickiness occurs.

The vinylpyrrolidone / dimethylaminoethyl methacrylate diethyl sulfate copolymer is contained in an amount of 0.05 to 10.0% by weight, preferably 0.2 to 10% by weight, based on the total composition.
