PURPOSE: To obtain the subject preparation having improved uniform miscibility with hair-dye cream, etc., by adding a specific amount of a carboxyl-containing thickening polymer, etc., soluble in an alkaline solution to the subject O/W-type preparation containing an oil or fat component, an emulsifier and hydrogen peroxide. n CONSTITUTION: This preparation is easily and uniformly miscible with a hair-dye cream or bleaching cream of an emulsion form and, accordingly, suitable for putting in a 2-compartments mixing and application container and gives a dyed or bleached hair having remarkably improved color density and gloss. The preparation is produced by adding 1-5wt.% (in terms of solid based on the total preparation) of a carboxyl-containing thickening polymer or copolymer soluble in an alkaline solution, preferably a thickening polymer or copolymer of acrylic acid or methacrylic acid to the subject O/W-type preparation containing (A) an oil or fat component, (B) an emulsifier and (C) hydrogen peroxide. n COPYRIGHT: (C)1989,JPO |
