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.
A hair conditioning shampoo comprising:
A shampoo according to claim 4 wherein the water insoluble conditioning agent includes an aminosilicone of the formula ##STR2## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5 and R.sup.7 are alkyls of 1 to 6 carbon atoms, R.sup.4 is --R.sup.8 --NH--CH.sub.2 CH.sub.2 --NH.sub.2, R.sup.8 is alkylene of 3 to 6 carbon atoms, x is an average number in the range of 100 to 10,000 and y is an average number in the range of 0 to 10, which is of an amine equivalent in the range of 4,000 to 60,000, and a long chain alkyl-containing compound is present, which is a long chain alcohol or a long chain lower alkoxylated alcohol of an average of about 30 to 40 carbon atoms n the long chain alkyls thereof, in which such alkyls are of even numbers of carbon atoms, and which alcohols are of substantially bell-shaped distribution curves (% by weight vs. chain length).
A shampoo according to claim 12 which comprises 0.5 to 5% of the long chain alkyl-containing alcohol, alkoxylated alcohol thereof and mixtures of both.
