PREPARATION OF EMULSION HAVING A ROUND BEAD FORM BY FREEZING AT LOW TEMPERATURE AND THUS PREPARED EMULSION HAVING A ROUND BEAD FORM

摘要

The present invention relates to a method for manufacturing solid round emulsion beads by dropping liquid emulsion into a cryogenic freezing refrigerant. The obtained solid round emulsion beads can be stored and used at a low temperature. The solid round emulsion beads can be coated with a solution containing a material which is solid at room temperature or which can form gel. The emulsion beads can be prepared by using liquid emulsion containing additional material, which is solid at room temperature or can form gel, in the water phase of oil-in-water (O/W) emulsion or the oil phase of oil-in-water (W/O) emulsion. The emulsion beads prepared by the present invention can maintain its shape without swelling and/or damage but with stability and does not give any grainy feeling when the liquid emulsion was applied on the skin.
