Abstract
This invention relates to cationic oil-in water emulsion compositions which are especially useful as hair conditioning compositions which have a sparkling pearlescent appearance due to the presence of irregular platelet-like crystals suspended in the composition. The compositions comprise a cationic water-in-oil emulsion of from (a) about 0.1% to 5%, preferably from 0.1 to 0.8%, of a quaternary ammonium compound such as stearyl dimethyl benzyl ammonium chloride; (b) about 1-10%, preferably 1-2%, of a fatty acid having 12-16 carbon atoms such as myristic acid and a fatty monoalcohol having from 12 to 18 carbon atoms such as cetyl alcohol in a 70:30 to 95:5, preferably 75;25 to 85:15, weight ratio of acid to alcohol; (c) about 0.5-2% of a compatible thickening agent such as hydroxyethyl cellulose; optionally, up to bout 5% of additional cationic, nonionic and amphoteric surfactants; and the balance comprises water wherein the pH of the emulsion is from about 2-5, preferably from 2-4, and the viscosity is preferably from about 1,000 to 5,000 centipoise at 25.degree.
