Abstract: 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.
