COSMETICS COMPRISING MULTI-LAYER NANOPARTICLES HAVING NATURAL INSOLUBLE MEDICINE ENCAPSULATED THEREIN AS PRESERVATIVE, AND METHOD FOR PRODUCING SAID COSMETICS

摘要

The present invention relates to cosmetics comprising a preservative, more specifically to cosmetics having an excellent long-term storage characteristic by comprising multi-layer nanoparticles as a preservative, the multi-layer nanoparticles, which has natural insoluble medicine encapsulated therein, stably maintaining medicine content while maintaining a set size of 0.001-40 nm not only immediately after production but even after long-term storage, and forming no precipitates when used as a preservative for liquid cosmetics.
