Abstract
Abstract A homogeneous liquid amphoteric-nonionic based antidandruff 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 four component mixture of the following specific ingredients: a. about 6-30% by weight of cocobetaine, cocosulfobetaine, cocoamidobetaine, cocoamidosulfobetaine or combinations thereof, b. about 1-7.5% by weight of a tertiary amine oxide, c. about 1-7% by weight of a fatty acid mono- or di-ethanolamide, d. about 0.1-5.0% by weight of a polyoxyethylene hexitan mono-higher fatty acid ester, and preferably e. about 0.01-0.1% by weight of a polymerized quaternized ammonium compound. This shampoo is transparent in appearance and should preferably contain 65-80% water.
