摘要
在防晒化妆品中加入无机或有机UV吸收剂是目前行之有效而且广泛使用的方法,然而因其悬浮和分散性能不佳,会影响对紫外线的阻挡能力以及配方的稳定性。文章介绍了防水型防晒产品中的成膜聚合物和一种新型的增稠剂,该聚合物可给予无机UV吸收剂更好的性能。
Inorganic and organic UV filters have a long history of safety, yet both technologies can beset formulators with technical challenges. However, insufficient suspension and dispersion can cause deterioration of their UV-blocking ability as well as long-term formulation stability issues. For these reasons, formulators may be reluctant to use inorganic UV filters in formulations. It looks at film forming polymers and a novel thickener that together afford greater utilization of inorganic UV filters in water-resistant sunscreen products.
