Claim:
1. A topical composition comprising: a) one or more ultraviolet radiation (UVR) filtering agents selected from the group consisting of ultraviolet A (UVA) radiation filtering agents avobenzone, diethylamino hydroxybenzoyl hexyl benzoate, meradimate and ecamsule; and b) at least one UVR filtering agent selected from the group consisting of ultraviolet B (UVB) radiation filtering agents octocrylene at a concentration from 0.5% to 7% (wt), oxybenzone at a concentration from 0.9% to 3.6% (wt), octisalate at a concentration from 1.1% to 4.2% (wt), benzophenone-4 at a concentration of 5% (wt) or less and homosalate at a concentration of 0.5% to 7% (wt), wherein: the UVR filtering agents are present in the composition in an amount effective to filter UVA when the composition is applied to the skin of a human exposed to UVR; the composition allows passage of 25% or more of the UVR in the 295 nm to 315 nm range when applied to the skin in the amounts of between 0.01 and 50 milligrams per square centimeter; the composition allows passage of radiation in the approximately 295 to 315 nm range to permit production of vitamin D when the composition is applied to the skin of a human exposed to UVR; and the composition does not include zinc oxide at a concentration of 0.25% (wt) or more, titanium oxide at a concentration of 0.25% (wt) or more, or cerium oxide at a concentration of 0.25% (wt) or more.
