VITAMIN C DERIVATIVE AND MANUKA OIL SURFACE TREATED COMPOSITE POWDER FOR SKIN-WHITENING AND WRINKLE-CARE

摘要

The present invention relates to composite particles for skin-whitening and wrinkle care and, more specifically, to composite particles which are applied with functional foods such as vitamin C derivative and manuka oil and the like. The present invention provides a multi-functional cosmetic composition which has skin-whitening and anti-inflammatory activities as vitamin C derivative and manuka oil do, and is obtained by the steps of manufacturing nanoemulsion including the vitamin C derivative or manuka oil; checking phase stability of the nanoemulsion obtained from the above step; coating the nanoemulsion including the functional foods with inorganic powder; quantifying contents of the vitamin C derivative from the vitamin C derivative coated powder obtained from the above step and quantifying contents of organic matters from the manuka oil coated powder; analyzing particle size of the functional foods coated powder; and checking skin-whitening and wrinkle care effects through animal experiments. The present invention improves phase stability and keeps the coated organic matters intact.
