Abstract: A hair treatment composition comprises particles having a first non-aqueous phase and, retained within said first non-aqueous phase, a second hydrophilic phase which is an aqueous solution, dispersion, emulsion or a solid or liquid having a log P value less than 1, said second phase comprising a hair benefit agent, wherein said first non-aqueous phase has a melting point of from 30° C. to 100° C.

Abstract: Rinse off hair treatment compositions comprise particles wherein at least 90% by weight of the particles have an average maximum dimension of from 10 nm to 300 &mgr;m, the particles comprising a silicone wax having one or more C3 to C40, branched or unbranched, saturated or unsaturated, optionally substituted hydrocarbon groups and the wax having a melting point of from 30° C. to 100° C. The compositions can be used in a method of treating hair which comprises: applying to the hair particles wherein at least 90% by weight of the particles have an average maximum dimension of from 10 &mgr;m to 300 &mgr;m, the particles comprising a silicone wax having one or more C3 to C40, branched or unbranched, saturated or unsaturated, optionally substituted hydrocarbon groups and the wax having a melting point of from 30° C. to 100° C.; and heating the hair to a temperature above the melting point of the particles. The method can act to condition the hair.
