Abstract
A hair conditioning shampoo is described, which contains C.sub.6, C.sub.8 and/or C.sub.10 alkyl sulfate and/or C.sub.6, C.sub.8 and/or C.sub.10 alkyl lower alkoxylate sulfate as an anionic detergent component, a water insoluble conditioning agent(s) from the group of silicones (preferably a certain type of aminosilicone), polyethylenes, paraffins, isoparaffins, microcrystalline waxes, C.sub.18-36(mixed) fatty acids or such triglycerides, high fatty alcohol ester of a high fatty acid (such as stearyl stearate), beeswax, cationic conditioning agent, such as a quaternary ammonium or any mixture thereof, and a stabilizer for the shampoo, in water. Among adjuvants that may be present are lauric monoethanolamide, cocodiethanolamide, and hydroxyethyl cellulose, other thickeners and viscosity modifiers, pH adjusting agents, antioxidants perfumes and colorants. The presence of the C.sub.6, C.sub.8 and/or C.sub.10 alkyl sulfate and/or C.sub.6, C.sub.8 and/or C.sub.10 alkyl lower alkoxylated sulfate surprisingly improves conditioning of the hair, compared to shampoos containing other detergents that contain longer chain alkyl groups.
