Abstract
High sudsing detergent compositions comprising N-alkoxy polyhydroxy fatty acid amides are provided by the addition of secondary carboxylate surfactants. Thus, cocofatty acid N-(3-methoxypropyl) glucamide is used in liquid, granular or bar compositions in combination with conventional detergent ingredients and secondary fatty acids such as 2-methyl undecanoic acid. The compositions exhibit high, relatively persistent suds and high emulsifying and cleaning properties, especially with respect to greasy soils of the type commonly found on eating utensils and in food stains on fabrics.

A detergent with high sudsing characteristics, comprising:
- (a) at least about 1% by weight of an amide nonionic surfactant of the formula ##STR3## wherein R is a C.sub.7 -C.sub.17 hydrocarbyl moiety, R.sup.1 is a C.sub.2 -C.sub.4 hydrocarbyl moiety, R.sup.2 is a C.sub.1 -C.sub.3 hydrocarbyl or oxy-hydrocarbyl moiety, and Z is a polyhydroxy hydrocarbyl unit having a linear chain with at least two hydroxyls directly connected to the chain;
- and
- (b) at least about 1% by weight of a secondary soap.
