Cover Story: Heterografted copolymers varied by ratio of PEG/PCL side chains are proposed as carriers designed for the delivery of substances applicable in cosmetology that include dermatological problems. The self-assembling copolymers formed micelles with the ability to encapsulate cosmetic substances, e.g., arbutin, vitamin C, 4-n-butylresorcinol. The nature of the loaded substance interacting with polymer matrix is crucial in kinetic release profiles. The permeation tests of the active substance released through a membrane acting as human skin in Franz chambers indicated a moderate diffusion into solution and remained in the membrane, which is satisfactory for most cosmetic applications.
