PROBLEM TO BE SOLVED: To obtain the subject composition high in foamability and improved in low temperature stability and color tone stability by adding a specific aryl carboxylic acid salt or ester to a highly washable composition comprising a specific composition. SOLUTION: This composition contains (A) 40-70 wt.% of a linear alkylbenzenesulfonic acid salt (preferably containing a 10-13C alkyl group in an amount of >=90 wt.% and having a 2-ϕisomer content of >=5%), (B) 10-40 wt.% of a polyoxyethylene alkyl ether, (C) 10-40 wt.% of a higher fatty acid diethanolamide, and (D) 0.1-5 wt.% of a 7-12C arylcarboxylic acid or its salt or ester (preferably benzoic acid or its salt or ester) as essential components, and the total amount of the components A-C is 70-90 wt.% in the composition. The salt of the component A preferably contains an alkanolamine salt. The pH of the raw liquid of the composition is preferably 5.0-8.0. |
