Abstract
Detergent compositions containing N-(1,2 propanediol) fatty acid amide surfactants of the general type RC(0)NR.sup.1 CH.sub.2 CHOHCH.sub.2 OH, especially where R.sup.1 is methyl or hydroxyethyl, are useful surfactants in laundry detergents, dishwashing liquids, shampoos, bar soaps, and hard surface cleaners. The amide surfactants provide good cleaning even in the absence of LAS surfactants.
Claims1
A method for cleaning soiled tableware, comprising contacting said tableware with an aqueous medium containing an effective amount of a composition comprising:
- (a) from about 1% to about 30% by weight of an N-(1,2-propanediol) fatty acid amide surfactant of the formula ##STR17## wherein R is a C.sub.7 -C.sub.21 hydrocarbyl species and R.sup.1 is a C.sub.1 -C.sub.6 hydrocarbyl or substituted hydrocarbyl species,
- (b) at least about 1% by weight of one or more non-amide detersive surfactants;
- (c) from 0% to about 50% by weight of a detergency builder;
- (d) from 0% to about 5% by weight of a detersive enzyme;
- (e) from 0% to about 25% by weight of active adjunct materials;
- and
- (f) the balance of the composition comprising moisture and carrier ingredients, said contact being under conditions of agitation.
