ABSTRACT:
Isethionate salts have been discovered to provide protection for the skin against damage from contact with soap or other surfactants. A mild to the skin cleaning composition is provided comprising fatty acid soap in amounts greater than 25% and an isethionate salt such as sodium isethionate, the ratio of soap to isethionate ranging from 1:2 to abut 200:1. Sodium C.sub.8 -C.sub.18 acyl isethionate may be incorporated as a further component into the cleaning composition, although in an amount not to exceed that of the soap.
