One amphiphilic polymer coated micelles coated with a retinoid and a cosmetic composition

One amphiphilic polymer coated micelles of retinoid A coating composition and cosmetics, chemistry and applications of polymer materials belonging to technical field. The present invention were prepared by dialysis method amphiphilic polymer coated micelles of retinoid A coating, freeze-dried as a powder, and retinoids A coated micelles added to the cosmetic composition. The results show that the amphiphilic polymer coated micelles of retinoid A coating can significantly improve the stability of the retinoids A, vitamin A-based sustained release. The present invention is made of an amphiphilic polymer coated micelles of retinoid A coating, can be used in various types of cosmetic compositions cream, cream, milk, and other liquid A containing a retinoid, to overcome the liposomes, solid defects in the use of the microcapsules lotion or the like.
