PROBLEM TO BE SOLVED: To provide a cosmetic detergent compsn. excellent in characteristics as a cosmetic by incorporating a detergent base contg. at least one anionic surfactant of an alkyl sulfate ether type and at least one amphoteric surfactant of an 8-20C alkylbetaine type, at least one aminosilicone, and at least one cationic polymer into the same. SOLUTION: This compsn. contains a conditioning system which contains a detergent base contg. 1-50 wt.% anionic surfactant (e.g. an 8-14C alkyl sulfate ether salt) and 1-50 wt.% amphoteric surfactant (e.g. an 8-20C alkylbetaine of formula I). 0.05-5 wt.% aminosilicone of formula II, and 0.001-10 wt.% cationic polymer of formula III or IV. In formulas I to IV, R1 and R2 are each 1-22C alkyl, etc.; R3 is H or methyl; k and t are each 0 or 1 provided k+t is 1; x' and y' are each such a value as to give a wt. average mol.wt. of 5,000-50,000; and Y<-> is the anion of a bromide, a chloride, acetic acid, boric acid, citric acid, bisulfuric acid, sulfuric acid, phosphoric acid, etc. |
