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.

A toilet bar composition consisting essentially of:
- (a) from 30 to 70% alkali metal fatty acid soap;

- and
- (d) from 5% to 45% sodium C.sub.8 -C.sub.18 acyl isethionate, the amount of acyl isethionate being no greater than the amount of soap present.
