ABSTRACT:
A process of producing a solid cosmetic includes continuously repeating the steps of feeding a cosmetic base containing a powder and an oil as main ingredients into a heating cylinder from a hopper, causing the cosmetic base to be injected into a mold by forward motion of a screw or plunger, and cooling the thus-injected cosmetic base to solidify in the mold.
