The emulsion composition is properly mixed with 1-60wt.% of an oil component and conventionally used cosmetic components besides the polymer and the derivative and prepared into a shampoo, rinse, hair conditioner, hair treatment, set lotion, blow styling lotion, hair spray/hair cream, etc., in a form of an emulsion, suspension, gel, liquid crystal, aerosol, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsified composition for hair, which is particularly excellent in long-term stability without using a surfactant.
Further, the present invention relates to an emulsified composition for hair capable of adhering and repairing split ends of hair.

[0002]

2. Description of the Related Art Conventionally, creams and emulsions obtained by emulsifying various oily and aqueous raw materials have been widely used as cosmetic emulsion compositions. In the production of such an emulsified composition, it is essential not only to treat the raw material under various conditions that are strictly set, but also to use a surfactant in order to guarantee the temporal stability of the emulsified composition. Was said. However,
In recent years, even higher safety is expected for cosmetics, and the presence of a surfactant may be a problem from this viewpoint.

On the other hand, dimethyl silicone gum, polyvinylpyrrolidone type polymers, acrylic acid type polymers, polysaccharides, polypeptides and the like are blended in hair cosmetics for the purpose of coating the split ends of hair. In addition, recently, a hair cosmetic composition in which one kind of polysiloxane-oxyalkylene copolymer and a silicone derivative are used in combination,
It has been reported that it has a good feel and is excellent in the adhesion of split ends (JP-A-6-157247). However, with these methods, although the feel was good, the adhesion effect of the split ends and the gloss of the hair were still incomplete. Also, when other polymer compounds are mixed, there is an adhesive effect, but once peeled off, the effect is not reproducible, and there is a problem in the tactile surface such as squeaking, dryness, and stiffening. Many, and
There were also cosmetic problems such as flaking. Accordingly, there has been a demand for a hair cosmetic which can solve these problems, efficiently bond the split ends, and give the hair a gloss and a good feel to the hair.

[0004]

Under such circumstances, as a result of intensive studies by the present inventors, as a result of emulsifying and using a silicone derivative with an alkyl-modified carboxyvinyl polymer, the above-described hair emulsified composition can be obtained. Then, the present invention was completed.

That is, the present invention comprises an emulsion composition for hair characterized by containing an alkyl-modified carboxyvinyl polymer represented by the following general formula (1) and having a molecular weight of 500,000 to 3,000,000, and a silicone derivative. Is.
