Abstract
Abstract Detergent bars containing acyl isethionates can exhibit a feeling of drag (relatively high friction) when handled during washing. The drag can be reduced, and therefore the slip feeling of the bar improved, by adding a sucrose ester. Preferably the amount is from about 5 to about 30%.

Claim 1
Independent Claim
46 words
A detergent bar containing from about 20% to about 70% by weight of water soluble salts of acyl (C 8 to C 22 ) isethionates and an amount of sucrose ester (C 6 to C 22 ) effective to increase the slip properties of the bar.
Claim 2
Dependent Claim
46 words
A detergent bar containing from about 20% to about 70% by weight of water soluble salts of acyl (C 8 to C 22 ) isethionates and an amount of sucrose ester (C 6 to C 22 ) effective to increase the slip properties of the bar.
