CHARGE DONOR FOR VESICULAR CARRIER SYSTEM OF UV PROTECTIVE AGENT FOR SKIN OR HAIR

摘要

PROBLEM TO BE SOLVED: To provide a UV protective agent.SOLUTION: In order to prepare a UV protective agent for topical application to the skin or hair with very high UV filter substance concentration and with good adhesion to the skin and hair, the UV protective agent comprises at least one UV filter substance, which is encapsulated in a vesicular carrier system. The UV filter substance encapsulated in the vesicular carrier system is lipophilic and the vesicular carrier system consists of vesicles constructed from hydrophobized polysaccharides and having a particle size from 10 to 1000 nm, as well as a positive surface charge with a zeta potential in the range from 1 to 150 mV by means of charge donors contained therein. In addition, such a UV protective agent is used in corresponding cosmetic and/or pharmaceutical formulations.SELECTED DRAWING: None
