A novel imidazolinium salt is prepared by (1) reacting N-aminoalkyl-imidazoline, N-hydroxyalkyl-imidazoline, or N-substituted-imidazoline with an alpha , beta -unsaturated ester of a carboxylic acid, (2) reacting the resulting ester imidazoline with a primary or secondary amine and (3) quaternizing the resulting amido imidazoline product by reacting it with an alkylating agent. This imidazolinium salt is useful as a fabric softening agent.
