  摘要：

  本发明涉及一种新型防晒剂，具有吸收UVA和UVB波长辐射的能力。防晒剂包括一种特定类型的UVA吸收色团，与一种特定类型的UVB吸收色团共价键合。这些色团基团通过共价键结合在一起，使得这些基团的电子系统没有直接耦合。本发明还涉及包含上述类型防晒剂的防晒组合物。此外，本发明还涉及一种保护人类或低等动物皮肤免受UVA和UVB波长辐射影响的方法。该方法包括将本发明防晒组合物有效涂布于皮肤表面。

  Bridged polysilsesquioxane based sunscreens prepared as nanoparticles via oil/water microemulsion polymerization, sol-gel polymerizations, or a modified Stober 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 of were found to be comparable to existing commercial sunscreens. Furthermore the bridged polysilsesquioxane based sunscreens can be classified as broad-spectrum, and rate from moderate to superior in terms of UVA protective ability.

  基于桥联聚硅氧烷的防晒霜可通过油/水微乳聚合、溶胶-凝胶聚合或改良的Stober工艺制备成纳米颗粒。通过共价结合，实现了最小化渗漏和降低光降解水平，桥联结合对确保防晒霜及任何光降解产物与皮肤隔离是必要的。SPF值发现与现有商业防晒霜相当。此外，基于桥联聚硅氧烷的防晒霜可被归类为广谱，其UVA保护能力在中等到优越之间。

  The present invention relates to novel sunscreen agents which have the ability to absorb both UVA and UVB wavelength radiation. The sunscreen agents comprise a specific type of UVA-absorbing chromophore covalently bonded to a specific type of UVB-absorbing chromophore. The chromophore moieties are covalently bonded together such that the electron systems of these moieties are not directly coupled. The present invention further relates to sunscreen compositions containing the hereinbefore described type of sunscreen agents. Furthermore, the present invention relates to methods for protecting the skin of humans or lower animals from the effects of UVA and UVB wavelength radiation. This method comprises topically applying to the skin an effective coating of a sunscreen composition of the present invention.
