ABSTRACT:
Novel polymeric compositions and their intermediates are provided, providing 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 another hydrophilic monomer to provide sunscreen formulations for invisibility, and enhanced protection, without deleterious effects in the dermis.
