Patent number: 9174178Abstract: A mixing assembly for use in a semi-continuous process for producing liquid personal care compositions, such as shampoos, includes a main feed tube carrying a base of the composition to be produced, a plurality of injection tubes in selective fluid communication with the main feed tube, and an orifice provided in a wall at an end of the main feed tube downstream of the plurality of injection tubes. The wall in which the orifice is provided includes a curved (e.g., semispherical) entry surface on an upstream or inlet side of an orifice, and a curved (e.g., semi-elliptical) exit surface on a downstream or outlet side of the orifice. The orifice may have a rectangular or elliptical shape. By maintaining symmetry of the injection tubes with respect to the orifice, and leveraging delay between introduction of dosed modules and increased viscosity, effective mixing may be achieved with minimal energy.Type: GrantFiled: June 9, 2011Date of Patent: November 3, 2015Assignee: The Procter & Gamble CompanyInventors: Jason Andrew Berger, David Scott Dunlop, Yunpeng Yang, Douglas Allan Royce, Dawn Renee Knapek

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
