Description

The present invention relates to foam-like hair cosmetics, and in particular, has high elasticity of foam, has an appropriate feeling of foam retention without dripping, and can achieve both an appropriate defoaming speed as a hair cosmetic and hair. The present invention relates to a non-gas type foamy hair cosmetic that can give a high treatment feeling.

There are various types of hair care products such as mist type, emulsion type, cream type, oil type, aerosol type, etc. as hair care products on the market. As a relatively new type of form, non-gas type foam products are listed. It is done. Conventional foam-type hair care products were mainly aerosol-type foams and mousses, but non-aerosol-type foam-type products that do not use gas due to environmental concerns and changes in consumer preferences. This is because each company has come to propose. Such products are sometimes referred to as non-gas types or pump former types.

Among such non-gas-type hair care products, various products such as styling agents and bedclothes have been proposed as out bath products. For example, by containing a specific polyoxyethylene / polyoxypropylene decyl ether, a foam cosmetic (eg, see Patent Document 1) having excellent foamability and fine foam quality and excellent usability. Can be mentioned. However, although such hair cosmetics are excellent in foaming properties and creamy foam quality, they are not satisfactory from the viewpoint of foam retention and foam elasticity, and are especially applied to the entire hair when using the hair cosmetics. There is a problem such as dripping down. In addition, combining an anionic surfactant such as N-acylmethyltaurine salt or lauroylmethyltaurine salt with polyether-modified silicone at a specific ratio provides excellent foaming properties and a finely textured foam. Hair cosmetics (for example, see Patent Document 2 or 3), and hair cosmetic compositions for correcting hair with a combination of a cationic surfactant or amphoteric surfactant and a polyoxyethylene alkyl ether (for example, hair styling) , See Patent Document 4). However, regarding the former, since an anionic active agent that is said to be highly irritating is used, there is a concern about safety. In addition, both are suitable for rehabilitation, but are insufficient from the viewpoint of giving a feeling of care (treatment feeling) to the hair. In addition, by combining a specific polypropylene glycol or polyoxypropylene ether with a polyether-modified silicone or amino-modified silicone, a non-aerosol-type foamy hair cosmetic that is excellent in foam amount and foam quality and excellent in finish feeling (for example, And Patent Document 5), and a foam-like hair styling composition comprising a polyalkylene glycol, an oil component, and a surfactant (for example, see Patent Document 6). However, the latter is more suitable for aerosol foams, but as non-gas type foams, the stability and foaming power of the agents are not satisfactory, both of which are excellent in touch etc. I was not satisfied with the sex.

Therefore, foam-like hair that has high foam elasticity, has a suitable foam-holding feeling without dripping, and can achieve both a suitable defoaming speed as a hair cosmetic and can impart a high treatment feeling to the hair. The development of cosmetics was strongly desired.

Japanese Patent No. 3663387 Japanese Patent No. 4256092 JP 2003-160447 A JP 2001-226233 A Japanese Patent No. 4619579 JP 2003-95895 A
