The present invention relates to a cosmetic composition containing the following Components (A), (B), and (C): Component (A): a hydrophobic polymer which dissolves in ethanol at 25° C. in an amount of 1% by mass or more, and has a glass transition temperature Tg of 30° C. or higher, the polymer having the same electric charge as the following Component (B), or not having an electric charge; Component (B): a hydrophilic ionic polymer which dissolves in ethanol at 25° C. in an amount of 1% by mass or more; and Component (C): an ionic polymer which dissolves in ethanol at 25° C. in an amount of 1% by mass or more, the ionic polymer having a different kind of an electric charge to that of the Component (B). The cosmetic composition of the present invention can be suitably used in cosmetics for hair.

Cosmetic composition

The present invention provides polyether polycarbonate having a constituent unit represented by the formula (I), a method for producing the same, an adhesive composed of the same, an adhesive composition containing the same, an adhesive sheet having a layer of the adhesive composition, a method for producing an adhesive article by dissolving the polyether polycarbonate in a solvent selected from water and alcohols having 1 to 4 carbon atoms, coating the solution on an adherend, and volatilizing the solvent, and an alcohol solution containing the polyether polycarbonate. where A represents an alkylene group having 2 to 6 carbon atoms; n represents an average number ranging from 5 to 1,000; and p represents an average number ranging from 5 to 100, wherein (n&#xd7;p) A's may be the same as or different from one another.

Polyether polycarbonate

A hair cosmetic composition containing a polyether polycarbonate having a structural unit represented by the following formula (1): [wherein A represents a C2 to C6 alkylene group; n represents an average number of 5 to 1,000; p represents an average number of 5 to 100; and (n&#xd7;p) units of AO may be the same or not]. 

Hair cosmetic composition

Hair dye compositions

This invention relates to a hair cleansing composition, which comprises (A) 0.01 to 20 wt. % of glycine or alanine, (B) 0.01 to 5 wt. % of an &agr;-hydroxy acid, &bgr;-hydroxy acid, 1,2-dicarboxylic acid, 1,3-dicarboxylic acid or aromatic carboxylic acid, and (C) 5 to 40 wt. % of an anionic surfactant selected from an alkylsulfuric acid salt, an alkylethersulfuric acid salt or an N-alkylamidoalkanolsulfuric acid ester salt. The hair cleansing composition is excellent in the effect of improving optical or mechanical properties of hair.

Hair cleansing compositions containing glycine and alanine

A hair care product which comprises a salt of an acylated compound obtained by condensing fatty acids containing at least 40% of branched fatty acids having 20 to 32 carbon atoms with silk protein-derived peptides, which hair care product is effective in imparting a good texture and preventing the hair from damages (split hair, clipped hair, etc.) without giving any tackiness or greasiness.
