ABSTRACT:
The invention relates to properties and uses of N-hydrocarbon substituted lactams, particularly N-alkyl substituted lactams having the formula ##STR1## wherein R' is a hydrophobic radical such as linear or branched chain alkyl group containing from 8 to 27 carbon atoms, most preferably micelle forming pyrrolidones having 12 to 16 carbon atoms in the R' group. The invention particularly relates to the uses of the N-hydrocarbon substituted lactams which involve surfactant properties, such as solubility, wetting, viscosity building, emulsifying and/or complexing properties.
