摘要:
A liquid detergent composition is disclosed, which has a pH value ranging from 6 to 8 and comprises the following Components (A), (B) and (C):(A) an N-acylamino acid salt represented by formula (1):R.sup.1 CONH(CH.sub.2).sub.n COOK (1) wherein R.sup.1 CO represents a straight-chain acyl group having 10 to 16 carbon atoms, n is a number of 1 or 2 and K is potassium;(B) a water-soluble anionic surfactant selected from the group consisting of an alkylsulfuric acid salt, a polyoxyethylene alkyl ether sulfuric acid salt, an amidoamino acid salt, an N-acylmethyltaurine salt, a polyoxyethylene alkylsulfosuccinic acid salt, an N-acylmethyl-.beta.-alanine salt, an N-acylsarcosine salt and an acylglutamic acid salt; and(C) water,wherein a weight ratio of the component (A) to the component (B) is from 6/1 to 1/3. The liquid detergent of the present invention is hardly irritative to the skin and hair, has high detergency and gives excellent feeling during and after use.
