Abstract:
1. A cleansing or a surface-conditioning composition comprising a mixture of (i) and (ii) in water: i) a surfactant selected from the group consisting of anionic, non-ionic, zwitterionic, cationic, or mixtures thereof; and ii) a hydrophobic benefit agent composite material in a particulate form having a mean particle size in the range of 1-1,000 micron, and a specific gravity of ≧1, not encapsulated within a film or a capsule-like enclosure, wherein said hydrophobic benefit agent composite material comprises oil phase droplets of an oil-in-water emulsion formed by emulsifying water, at least one hydrophobic liquid, and a hydrophobically-modified smectite clay thickening agent with a surface-active or water-insoluble anionic polymer and a high molecular weight hydrophilic cationic polymer that is insoluble in 3wt% or higher anionic surfactant solutions to form a thickened oil-in-water emulsion; and thereafter homogenizing the thickened oil-in-water emulsion with a hydrophilic, ultra high molecular weight cationic polymer to adsorb cationic polymer particles on the surface of the benefit agent composite droplets, wherein the adsorption of the cationic polymer particles on the surface of the benefit agent composite droplets is achieved prior to the addition of ii) to i).
