Abstract

Abstract A detergent composition which has a low irritation effect to human skin containing as an active surfactant component one or a mixture of compounds having the formulas <IMAGE> (1) <IMAGE> (2) wherein R is saturated or unsaturated hydrocarbon having 10 to 16 carbon atoms, X1 and X3 are hydrogen, alkali metal, ammonium, alkylammonium or substituted alkylammonium, and X2 is alkali metal, ammonium, alkylammonium or substituted alkylammonium, with the provisos that both X1 and X2 are not alkali metal and that when R has an average carbon atom number of 10, X1 is hydrogen, and wherein the weight ratio of the formula (1) compound(s) : formula (2) compound(s) is from 100:0 to 80:20.
