Patent number: 5230874Abstract: 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.Type: GrantFiled: August 5, 1992Date of Patent: July 27, 1993Assignee: The Procter & Gamble CompanyInventors: Anthony D. Sabatelli, Josephine A. Spirnak
