Abstract

This invention is an improved mild personal cleansing syndet bar comprising: long chain synthetic surfactant having essentially saturated C.sub.15 -C.sub.22, preferably C.sub.16 -C.sub.18, alkyl or acyl chains, more preferably cetearyl sulfate; a high lathering, mild synthetic surfactant, preferably C.sub.12 -C.sub.14 acyl isethionate; soap; fatty acids; sodium isethionate; paraffin wax, preferably a high melting point paraffin wax, and optionally, but preferably, cationic polymer. The bar has improved processability, good smear and in-use properties as well as improved mildness and rinsability without meaningful lather negatives.
