摘　　要：天然高分子物质海藻酸钠和壳聚糖为材料以复凝聚反应包裹化学紫外线吸收剂,以减少其在使用过程中的不利作用(如光毒性和光过敏等现象),结果表明包裹后既保留了化学紫外线吸收剂的吸收紫外线的效应,同时因为包裹材料的多糖结构和物理漫反射作用也起到了加强紫外线吸收的效果,并且大大改善了其对皮肤的亲和性。Chemical Ultraviolet （UV） absorbers were embedded by Sodium alginate and chitosan, which are natural polymeric materials and formed microspheres by complex coacervation, in order to reduce their offside including of photo toxicity and photo sensitization etc.. The microspheres displayed good UV absorption effects, which retained effect of the chemical UV absorbers, absorbed UV radiation due to muhisaccharide structure of shell and diffused radiation physically by microspheres, meanwhile it also improved affinity to skin.
