ABSTRACT:
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.
