Patent number: 11896689Abstract: A method of making a personal care composition that involves using a mixer to combine a personal care composition chassis with microcapsules. The mixer has a housing, a first fluid inlet, a second inlet, a fluid outlet and a rotor connected to the housing. The rotor has blades positioned within the housing to define cells between neighboring blades and the housing. The personal care composition chassis, which includes surfactants and water, is advanced along a flow path from the first fluid inlet toward the fluid outlet, while the microcapsules are transferred from the second inlet to the flow path by rotating the rotor. Air in the microcapsule composition is directed from inside the cells toward the second inlet, and the microcapsule composition is combined with the personal care composition chassis to form the personal care composition. The personal care composition is advanced from the outlet.Type: GrantFiled: June 22, 2020Date of Patent: February 13, 2024Assignee: The Procter & Gamble CompanyInventors: David Scott Dunlop, Eric Shawn Goudy

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
