Abstract
Method for exhaustively alkylating the amine content of an imidazoline product prepared from a higher fatty acid and a dialkylene triamine wherein the protonated species formed in the course of the alkylation reaction are repeatedly neutralized, followed in each instance by reaction with an essentially equivalent amount of the alkylating agent based on the free amine present until the starting amine content of said product is predominantly converted to quaternary ammonium derivatives.
