Abstract
Anti-microbial polymeric quaternary ammonium compounds and mixtures thereof, having linear chains which terminate in quaternary ammonium moieties, such compounds being formed by polymerization which is carried out in such a manner that the linear chains thereof are terminated in random fashion, the reaction resulting in the formation of the compounds being a one-step reaction between 1,4-dihalo-2-butene and a mixture of a difunctional tertiary amine and a monofunctional tertiary amine wherein the molar quantity of the difunctional amine is greater than the molar quantity of the monofunctional amine. These products are especially effective hair conditioning agents.
