Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a hair styling composition used as a hair styling agent such as a hair setting lotion, a hair setting gel, a hair spray, a foamy hair styling agent, or as a base thereof. More specifically, it has a hard set-holding property for hair, dries quickly, has little stiffness or stickiness during and after use, and can give the hair a supple and smooth texture and a beautiful appearance, In addition, the present invention relates to a hair styling composition that can be easily removed at the time of washing hair and has an excellent feel to the hair at the time of washing hair.

[0002]

2. Description of the Related Art Heretofore, various polymer compounds such as anionic, cationic, nonionic and amphoteric have been used as a setting agent in hair styling products. Further, in consideration of the hair set-holding property and the finish texture, a combination of an anionic polymer compound and a cationic polymer compound (Japanese Patent Publication No. 62-7164) or an amphoteric polymer compound and a cationic polymer is used. Combination of compounds (Japanese Patent Publication No. 3-14805)
Japanese Patent Publication No. JP-A-2003-242240), blending an acrylic resin with a specific plasticizer such as a sorbit fatty acid ester ethylene oxide adduct (JP-A-53-99338), and blending a setting agent with a high molecular weight silicone (Japanese Patent Publication No. 7-80747) and the like are also proposed.

[0003]

However, the hair styling products using these hair styling products have a function as a hair styling product with the ability to hold the hair set, but since the hair dries slowly, it does not cause stickiness during and after use. Occasionally, the appearance of the hair was impaired due to the occurrence of stiffening after use, peeling of the setting agent (flaking), and the like. In addition, the setting agent cannot be easily removed with a detergent when washing the hair, and the film left on the hair surface may give squeaks to the hair during washing, making it difficult to obtain a supple and good feel. Therefore, while satisfying the basic effect of the hair styling product, that is, hard set retention of hair, it dries quickly, has little stiffness or stickiness during and after use, and has a good finished texture and beautiful appearance. Moreover, it is a hair styling product or its base that can be easily removed by washing hair and has an excellent feel.
The development of new hair styling compositions has been desired.

[0004]

Under the circumstances, the present inventor has conducted diligent research to solve the above-mentioned problems, and as a result,
By combining a specific nonionic polymer compound, a polymer compound consisting of a specific compound and sodium polyaspartate, the hair can be hard set as a hair styling agent, drying quickly, and it is not sticky or sticky during and after use. The present invention has been completed by discovering that the hair has a small amount, a supple and smooth texture, and a beautiful appearance without flaking, can be imparted, and that the setting agent can be easily removed at the time of washing the hair, and the feel of the hair is excellent. Came to.
