Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hair cosmetic composition for reclining bedclothes that has an excellent effect of relieving bedclothes, has good elongation when applied to hair, has very little stickiness, and gives the hair an excellent luster.
[0002]
[Prior art]
It is considered that wrinkles of hair such as sleeping crabs are caused by sleeping in the undried state after washing the hair, or sleeping sweat while sleeping. As a method for repairing this litter, generally, water is applied directly to the hair, or a hot steaming towel is wrapped around and then a heating device such as a brushing or a dryer is generally used. However, in these methods, in order to completely correct the bedclothes, it is necessary to apply a considerable amount of moisture to the hair and dry it, which takes time. In particular, it is very troublesome to use a heating device such as a dryer. . Therefore, there is a strong demand for a hair cosmetic that can easily and quickly recover litter.
[0003]
For example, JP-A-62-2788 discloses a composition comprising water / ethanol, a polyoxypropylene polyhydric alcohol phosphate ester and polyoxyalkylene methylpolysiloxane, and JP-A-62-2409. JP-A-2001-226233 proposes a composition comprising a linear or branched alkyl ether of polyoxyethylene as a composition comprising a quaternary ammonium salt, a branched fatty acid and an oily substance. However, these compositions are not satisfactory in the effect of relieving bed, and the polyoxypropylene polyhydric alcohol phosphate ester, branched fatty acid and polyoxyethylene in the process of hair drying after treatment. The linear or branched alkyl ethers of the present invention were very sticky.
[0004]
JP-A-5-163122 proposes a composition comprising a dimethylpolysiloxane microemulsion obtained by emulsion polymerization, a dimethylpolysiloxane polyoxyalkylene copolymer and water. However, although this composition is excellent in temporary relieving effect and imparting gloss, it has a problem that it may be squeaky depending on the molecular weight of dimethylpolysiloxane when applied to hair.
[0005]
