Appellants' claimed invention is directed to a process for
manufacturing a personal care composition that comprise oil and water
emulsions and variants, such as colors and fragrances. The aqueous phase is
delivered by an electronically controlled servo-driven rotary pump from a
first vessel into a blending tube, and then downstream from the blending
tube, a so-called late variant addition phase, such as a liquid material
comprising a fragrance or colorant, is fed into the base composition after it
leaves the blending tube. Appellants explain in the Specification that when
only a fragrance or color change is necessary in formulating a different
product, turn around preparation, which includes cleaning the feed lines, is
costly both in time and material (see page 2 of Specification). The present
invention solves this problem by adding the variant, such as fragrance or
color, downstream from the blending tube, thereby obviating the need to
clean the blending tube and the vessel wherein the aqueous phase is
