Abstract

Disclosed are aqueous conditioning shampoo compositions which comprise an anionic detersive surfactant component; from about 0.025% to about 5% by weight of an water soluble or dispersible, cationic, non crosslinked, deposition or conditioning polymer; the conditioning shampoo may additionally comprise dispersed, liquid, droplets of a water insoluble, hair conditioning agent having a volume average particle diameter of from about 5 microns to about 125 microns. A homopolymer has a cationic charge density from about from about 2 meq/gm to about 4 meq/gm or a cationic charge density of from about 5 meq/gm to about 10 meq/gm; or an average molecular weight of at least 500,000. A copolymer is formed from one or more cationic monomer units and one or more nonionic monomer units or monomer units bearing a negative charge wherein the subsequent charge of the copolymer is positive. The cationic polymer, in combination with anionic detersive surfactant component and other essential components, provides improved deposition of the conditioning agent on hair or skin, even when the dispersed conditioning agent particles have a volume average particle size of up to about 125 microns. The composi…
