PURPOSE:To obtain a detergent composition excellent in an amount of foam and retaining property of foam, free from grating feeling in washing and excellent in feeling to user. CONSTITUTION:This composition is obtained by blending (A) an anionic surfactant (e.g. a sulfuric acid alkyl ester or an alkylbenzene sulfuric acid salt) with (B) a surfactant selected from an amphoteric surfactant (e.g. an alkyldimethylaminoaceticacid betaine or a 2-alkyl-N-carboxymethyl-N- hydroxyethylimidazolinium betaine) and a nonionic surfactant (e.g. a fatty acid alkanolamide or a saccharide fatty acid ester) and (C) a polyaspartic acid (salt). Furthermore, total blend amount of these components A and B is preferably 5-60wt.% and the blend amount of the component C is preferably 0.3-5wt.% based on the composition. The component C is obtained by a method of, e.g. heating and polymerizing aspartic acid. |
