Patent number: 8367048Abstract: 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 amphiphiles; (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. A process for preparing a shampoo composition comprises the steps of: (a) combining a fatty amphiphile, a secondary surfactant, and water at a temperature sufficient to allow partitioning of the secondary surfactant and the water into the fatty amphiphile to form a pre-mix; (b) cooling the pre-mix below the chain melt temperature of the fatty amphiphile 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.Type: GrantFiled: November 21, 2006Date of Patent: February 5, 2013Assignee: The Procter & Gamble CompanyInventors: Robert Lee Wells, Douglas Allan Royce, Eric Scott Johnson, Elizabeth Marie Marzonie Elsner, Jennifer Elaine Hilvert, Yingkun Jin, Brian Michael Hurley, Teresa Cuasay Manuel, Benjamin Parker Heath
