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 an ethosylated sorbitan ester. Preferably the amount of ester is from about 5% to about 30% by weight of the bar.
Claims9
A detergent bar containing from about 20% to about 70% by weight of water soluble salts of acyl (C.sub.8 to C.sub.22) isethionates and an amount of ethoxylated (about 1 to about 30 units) sorbitan ester, having from about 12 to about 22 carbon atoms in the acid derived portion effective to increase the slip properties of the bar.
