Abstract
Described are detergent compositions that exhibit reduced skin irritation properties while providing excellent cleaning and detergent characteristics. The detergent composition contains anionic and/or nonionic surface active materials that are at least mildly irritating to the skin and an amount of alkyl poly(ethyleneoxy)sulfonate sufficient to reduce the primary skin irritation potential of the detergent composition. The aliphatic poly(ethyleneoxy)sulfonate typically has a hydrophobe containing from 12 to about 22 carbon atoms and an average of from about 10 to about 30 ethyleneoxy groups, and is present in the detergent composition in amounts of from about 5 to about 50 percent of the total amount of surface active material in the detergent composition.
