ABSTRACT:
There are provided thermotropic liquid crystal polymer microcapsules which can show behavior of liquid crystal as it is within polymer phase due to phase separation between liquid crystal and polymer, so to be incorporated into cosmetic composition as an additive for visual effect, and in loading active ingredients within liquid crystal, can improve the stability of the active ingredients in cosmetic base; and a method for preparing the same; and cosmetic compositions containing the same.
