  UV absorbing monomers having one or more alkoxysilyl functional groups are produced through epoxide reaction chemistry. Sol-gel or emulsion polymerization of said UV absorbing monomers by themselves, or with alkoxysilane comonomers, affords nanoparticle sunscreens with reduced chemical exposure and improved photostability. Minimized leaching and decreased levels of photo-degradation were achieved with covalent incorporation to ensure isolation of the sunscreen chromophores and any photo-products from the skin.

  含有一种或多种烷氧基硅烷官能团的UV吸收单体是通过环氧反应化学制备的。使用这些UV吸收单体进行溶胶-凝胶或乳液聚合，或与烷氧基硅烷共聚单体一起进行，可以制备出纳米颗粒防晒霜，从而减少化学暴露并提高光稳定性。通过共价结合实现防晒剂色团和任何光降解产物与皮肤的隔离，从而实现了最小化渗出和降低的光降解水平。

  Bridged polysilsesquioxane based sunscreens prepared as nanoparticles via oil/water microemulsion polymerization, sol-gel polymerizations, or a modified Stöber process. Minimized leaching and decreased levels of photo-degradation were achieved with covalent incorporation, with bridged incorporation necessary to ensure isolation of the sunscreen and any photo-products from skin. SPF values were found to be comparable to existing commercial sunscreens. Furthermore the bridged polysilsesquioxane based sunscreens can be classified as broad-spectrum, and rated from moderate to superior in terms of UVA protective ability.
