摘要：
In order to prepare a UV protective agent for topical application to the skinor hair with very highUV filter substance concentration and with good adhesion to the skin and hair,according to theinvention the UV protective agent is proposed with at least one UV filtersubstance, which isencapsulated in a vesicular carrier system, in which the UV protective agentis characterized bythe fact that the at least one UV filter substance encapsulated in thevesicular carrier system islipophilic and the vesicular carrier system consists of vesicles constructedfrom hydrophobizedpolysaccharides and having a particle size from 10 to 1000 nm, as well as apositive surfacecharge with a zeta potential in the range from 1 to 150 mV by means of thecharge donorscontained therein. In addition, use of such a UV protective agent incorresponding cosmeticand/or pharmaceutical formulations is proposed.
