Abstract

Abstract A liquid detergent composition comprising: (a) disalt of an alpha-sulfonated fatty acid having the general formula (I): ##STR1## wherein R 1 is an alkyl or alkenyl group having 8 to 16 carbon atoms and M and M' are independently a cation capable of forming a water-soluble salt selected from the group consisting of substituted and unsubstituted ammonium groups; and (b) an poly(oxyethylene) alkyl ether sulfate having the general formula (II): R.sub.2 --O--CH.sub.2 CH.sub.2 O).sub.n SO.sub.3 M" (II) wherein R 2 is an alkyl group having 9 to 15 carbon atoms, n is a number of 0.5 to 7, and M" is a cation selected from the group consisting of alkali metals, alkaline earth metals, substituted and unsubstituted ammonium groups, and the weight ratio of the component (a) to the component (b) being within the range of from 1/5 to 1/2. This liquid detergent composition does not cause the formation of film of the salt of an poly(oxyethylene) alkyl ether sulfuric acid and has good detergency characteristics.
