Abstract
Compositions comprising an organic sunscreen in combination with (i) nylon particles, (ii) silica particles, and (iii) barium sulfate particles provide an improvement in SPF as compared to an otherwise identical composition lacking any one of the three ingredients (i)-(iii). The compositions advantageously provide high diffuse transmittance, giving a natural look to the skin.
