Abstract
Shampoo compositions comprise (a) from about 5% to about 50% of one or more detersive surfactants, by weight of the shampoo composition; (b) a dispersed gel network phase comprising, by weight of the shampoo composition, (i) at least about 0.05% of one or more fatty alcohols; (ii) at least about 0.01% of one or more secondary surfactants; and (iii) water; and (c) at least about 20% of an aqueous carrier, by weight of the shampoo composition; and, wherein the dispersed gel network phase has a melt transition temperature of at least about 38° C. A process for preparing a shampoo composition comprises the steps of: (a) combining a fatty alcohol, a secondary surfactant, and water at a temperature sufficient to allow partitioning of the secondary surfactant and the water into the fatty alcohol to form a pre-mix; (b) cooling the pre-mix below the chain melt temperature of the fatty alcohol to form a gel network; (c) adding the gel network to one or more detersive surfactants and an aqueous carrier to form a shampoo composition which comprises a dispersed gel network phase having a melt transition temperature of at least about 38° C.
