Abstract
The invention relates to a method of producing a mixture of a quaternary ammonium compound, fatty acid, fatty acid ester and tertiary amine salt in situ which is a highly functional mixture that is manufactured in a single step reaction whereby quaternization is completed without the aid of solvents, especially flammable solvents. The single step reaction process eliminates separate blending of individual components. The compositions obtained can be used as fabric softeners, in modified clays, as hair treating compounds and as disinfectants.
