1results about How to "Improve release ability" patented technology

This invention belongs to the field of cosmetic technology and provides a polymer nanomicelle, its preparation method, and its application. The polymer nanomicelle of this invention is prepared from an amphiphilic block copolymer and an active ingredient; the structure of the block copolymer is shown in the following formula; the number-average molecular weight of the PEG is 2000-4000; and the number-average molecular weight of the PCL is 1800-13000. This polymer nanomicelle encapsulates a high content of active ingredient, and its active physicochemical properties and sustained-release properties are significantly improved after encapsulation; when combined with the active ingredient, it exhibits better in vitro antioxidant activity and whitening activity, and is widely used in cosmetic active ingredient encapsulation technology.
