South Korean ODM cosmetics firm Cosmax and POSTECH (Pohang University of Science and Technology) researchers have developed a 'multi-emulsion platform' that precisely controls stability and the release rate of active ingredients in cosmetic formulations. The technology uses a W/O/W (water-in-oil-in-water) layered emulsion (a structure combining external aqueous and internal oil phases) and optimizes combinations of polymeric and small-molecule surfactants: polymers strengthen the emulsion film for stability, while small-molecule surfactants regulate how quickly actives move out. This allows tailored delivery and longer residence time of ingredients on skin, useful for next-generation sunscreens. The findings were published in Science Advances and stem from work at the new Pohang UIC (UV Innovation Center), a collaboration between Cosmax, POSTECH, and Pohang city.
