ABSTRACT:
A method of preparing certain bis-quaternary ammonium compounds and mixtures is disclosed. The method involves contacting a tertiary amine with a suitable amount of neutralizing acid, e.g. HCl, and subsequently contacting the resulting mixture with a suitable epoxide, e.g. epichlorohydrin, at an elevated temperature and in an amount that e.g. 2-hydroxypropylene-bis-1,3-(dimethyl stearyl ammonium chloride) is obtained in almost stoichiometric yields. The resulting bis-quaternary ammonium compounds can be incorporated into a hair conditioner whereby a softer feel and better control of hair is obtained.
The general structure for the resulting bis-quaternary ammonium compounds is as follows: ##STR1## wherein the R's are selected from the group consisting of alkyl, alkylamidoalkyl, aryalkyl, aryl, alkoxy, alkenyl, hydroxyalkyl, and carboxyalkyl and X is a negative radical from the epoxide used, e.g. epichlorohydrin.
