We evaluated the cytotoxicity of surfactants in human cells. Synthetic surfactants showed different cytotoxicity levels depending on their structures. The cytotoxicity of commercial washing products was determined mainly by the contents of surfactants. All of them induced premature senescence in normal cells, but not in tumor-derived or immortalized cells, under sublethal conditions. Residual surfactants might be a risk factor for skin aging.
