ABSTRACT A process for the production of low viscosity amphoteric surfac- tants Low viscosity amphoteric surfactants are prepared by quater- nization of low diamine content imidazolines by a process in which certain addition and temperature parameters are strictly observed. Imidazolines suitable as a starting material may be obtained by heating fatty acids and aminoethanolamine in an inert solvent until water is eliminated, removing the water formed from the reaction mixture by azeotropic distillation and, finally, distilling off the solvent and the residual amine.
