COSMETIC GEL BEAD MANUFACTURING METHOD AND APPARATUS

摘要

Uniform crushable gel beads for topical delivery of biologically or cosmetically active agents in cosmetic, pharmaceutical, etc. formulations are produced by injection of a hot gelling agent liquid into a cold moving stream of oil contained in a conduit employing a T-piece. Cold oil can be recirculated and the beads separated with a screen. Preferred beads are agar beads containing an active agent retained in the bead by a restraining polymer. Desired organic solvent adjuvants can be adsorbed on oil-absorbent microspheres and included in the beads.
