Abstract: A process which may be continuous is provided for manufacture of personal care product compositions. The process involves feeding a first water phase which is a concentrate containing most if not all water soluble ingredients of the composition into a blending tube. A second phase which can be oily or aqueous and a third water phase, the latter being essentially pure water, are also fed into the blending tube. All of the phases are transported through the tube at a flow rate of about 5 to about 5,000 lbs./minute and at a pressure of about 10 to about 5,000 psi. Preferably the tube leads into a homogenizer such as a sonolator.

Abstract: A process and equipment for manufacture of a swab article is provided wherein a stick is placed onto a conveyor, adhesive is applied to one or both ends of the stick, a portion of cotton coil is attached to the adhesive bearing end, and a shaper bar or similar means forces the cotton to assume a teardrop profile by applying force parallel to the stick, wherein the shaper bar or similar means moves in a direction perpendicular to the stick at a different rate of speed than that of the stick. Differences in the rate of speed reduce tailing of cotton normally associated with drag.
