Patent

CA 1339295

The invention relates to N-hydrocarbon substituted lactams, particularly N-alkyl substituted lactams having the formula (see fig. I) wherein R' is a hydrophobic radical such as linear or branched chain alkyl group containing from 8 to 20 carbon atoms, most preferably 8 to 14 carbon atoms; which lactams are capable of forming micelles in aqueous solutions irrespective of pH and have critical micelle concentrations of between about 1 x 10-3 and about 1 x 10-5 moles per liter. The invention also relates to the uses of the N-hydrocarbon substituted lactams which involve surfactant properties, such as solubility, wetting, viscosity building, emulsifying, foam boosting and/or complexing properties.
