Abstract
The present invention relates to novel surfactants based on readily available materials, i.e., glyceric acid. In particular, it relates to novel N-alkylglyceramide surfactants having the formula ##STR1## wherein R is a C.sub.8 -C.sub.24 straight or branch-chained, saturated or unsaturated aliphatic hydrocarbon. These surfactants can be used in detergent compositions as surfactants together with cosurfactants to greatly enhance foam stability of the detergent compositions.
