Novel polymeric biologically inert compositions and their intermediates, as well as sunscreen formulations comprising them and making them invisible, are provided for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with other monomers to provide sunscreen polymers as microparticles. The polymer microparticles, once imbibed with carrier compounds, change the refractive index, thus providing invisible sunscreen formulations which offer enhanced protection without adverse physiological effects.
提供了新型聚合生物惰性组合物及其中间体,以及包含它们并使其看不见的防晒配方,可提供广泛范围的紫外线辐射防护。丙烯酸聚合物包括至少两种不同紫外线吸收基团,具有不同的吸光范围,与其他单体一起使用,以提供作为微粒的防晒聚合物。一旦聚合物微粒吸收了载体化合物,它们改变了折射率,从而提供了无形的防晒配方,提供了增强的保护,而不会产生不良生理效应。
