Abstract
Abstract A hair conditioning shampoo composition comprising an emulsion of water; about 5 to about 65 percent by weight of an anionic cleaning surfactant, such as ammonium lauryl sulfate; from about 0.1 to about 20 percent by weight of a cationic di-long chain alkyl quaternary nitrogen-containing conditioning agent, wherein the long alkyl chains bonded to the nitrogen atom have from about 12 to about 22 carbon atoms per alkyl chain, such as distearyl dimethyl ammonium chloride; from about 0.5 to about 10 weight percent of a long chain fatty alcohol haing about 8 to about 32 carbons in the long chain, such as stearyl alcohol; from about 0.5 to about 10 weight percent of a non-volatile silicone; and about 0.1 to about 5% of an anionic crosslinked polymeric suspending agent.
