Abstract:
1. A shampoo composition consisting of: (a) from about 2% to about 35% by weight of at least one surfactant; wherein the surfactant is selected from the group consisting of anionic, cationic, amphoteric, or nonionic surfactants, or mixtures thereof, (b) from about 0.01% to about 10% by weight of a silicone oil having an internal phase viscosity of from about 5 csk about 50,000 csk, wherein said silicone oil is present as a preformed microemulsion of particles having an average particle size of less than about 0.15 microns, the emulsion comprising: (i) water, (ii) surfactants selected from the group consisting of TEA dodecyl benzene sulfonates, laureth 23 and combinations thereof and (iii) the silicone oil;  wherein the molar equivalent of surfactant in the shampoo composition is equal to or greater than the molar equivalent of surfactant in the preformed microemulsion; (c) from about 0.01% to about 10% by weight of a cationic deposition polymer selected from the group consisting of cationic cellulose polymers having a molecular weight of at least about 800,000 and cationic guar polymers having a molecular weight of at least about 800,000 and a charge density of at least about 0.1 meq/g; (d) an aqueous carrier; and (e) from about 0.1% to about 0.5% of a stabilizing agent.
