The present study has revealed that anionic surfactants derived from EOAA (ethylene oxide adducts of s-alcohols), especially, salts of sulfonatosuccinic acid monoesters of EOAA have a property of low irritation for skin or eye, and, furthermore, have a property of synergistic effect to eliminate the skin or eye irritation of other anionic surfactants by co-use. These efficiency should be occured from higher surface tension, lower wetting power, larger cmc and larger HLB compared with usual anionics.
Thus, salts of sulfonatosuccinic acid monoesters of EOAA can be used to the detergent for a hair or body shampoo and a light duty liquid detergent as a extremely lower irritating detergent raw material with high safety.
