Abstract
Microemulsion light duty liquid detergent with desirable cleansing properties and mildness to the human skin comprising four essential surfactants: a water soluble nonionic surfactant, a C.sub.8-18 ethoxylated alkyl ether sulfate anionic surfactant, a C.sub.10-20 paraffin sodium sulfonate surfactant, and a betaine surfactant.
