Abstract

Dual-usage aqueous liquid detergent compositions having suds compatability and improved cleaning, said composition containing from about 1% to about 60%, by weight of the composition, of a surfactant system wherein said surfactant system contains at least 35%, by weight of the surfactant system, of alkylethoxysulfate; from 0% to about 10%, by weight of the surfactant system, of nonionic surfactant; from 0% to about 10%, by weight of the surfactant system, of soap; further contains from about 0.001% to about 4.0%, by weight of the composition, of an anti-foam selected from organomodified silicone polymers with aryl or alkylaryl substituents combined with silicone resin and the primary filler is modified silica; and mixtures thereof; and contains from about 0.01% to about 2.5%, by weight of the composition, of a structurant.

Methods of using such detergent compositions for laundering textiles.
