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.
