Abstract
Abstract A homogeneous liquid anionic-amphoteric based antimicrobial conditioning shampoo which includes about 0.5 to 2.5% of the antimicrobial agent, 1-imidazolyl-1-(4-chlorophenoxy)-3,3-dimethylbutan-2-one, solubilized in an aqueous solution of critical amounts of a mixture of the following specific ingredients: a. about 10-40% by weight of an anionic sulfate or sulfonate surface active agent, b. about 0.1-7.5% by weight of an amphoteric surfactant selected from the group consisting of cocobetaine, cocosulfobetaine, cocoamidopropylbetaine, cocoamidopropylsulfobetaine or combinations thereof. c. about 1-6% by weight of a fatty acid mono- or di-ethanolamide, and preferably d. about 1.1-5% by weight of a nonionic surface active agent selected from the group consisting of a tertiary amine oxide, a polyoxyethylene hexitan mono-higher fatty acid ester, and mixtures thereof, and e. about 0.5-2% by weight of a lower aliphatic monohydric or polyhydric alcohol or mixtures thereof.
