1. A method of molding a personal care product comprising:
combining in a holding container a first phase and a second phase of material to form a multiphase material;
pumping the multiphase material from the holding container to a recirculation tank;
continuously moving the multiphase material from the recirculation tank through a temperature controlled manifold;
while continuously moving the multiphase material through the temperature controlled manifold:
opening one or more injection valves between the temperature controlled manifold and one or more mold cavities;
injecting the multiphase material at a controlled pressure into the one or more cavities in a closed position to form one or more articles;
closing the one or more injection valves between the temperature controlled manifold and one or more mold cavities after injecting the multiphase material into the one or more mold cavities;
opening the one or more mold cavities; and
removing the one or more articles from the one or more mold cavities.
