Claim 25:
26. A method of making a personal care composition, the method comprising steps of:
providing a mixer comprising a housing comprising a first fluid inlet, a second inlet, a fluid outlet, and a rotor rotatably connected with the housing, wherein the rotor comprises blades positioned within the housing to define cells between neighboring blades and the housing;
preparing a personal care chassis base comprising surfactants and water;
preparing a microcapsule composition comprising microcapsules and an aqueous carrier;
advancing the personal care chassis base along a flow path from the first fluid inlet toward the fluid outlet;
transferring the microcapsule composition from the second inlet to the flow path by rotating the rotor; wherein air enters the microcapsule composition in the flow path;
directing the air in the microcapsule composition from inside the cells toward the second inlet;
combining the microcapsule composition with the personal care chassis base to form the personal care composition; and
advancing the personal care composition from the fluid outlet.
