ABSTRACT:
A cosmetic sunscreen composition is described that includes an emulsion formed from water, an emollient oil and an organic sunscreen agent capable of absorbing ultraviolet radiation within the range of 290 to 400 nm. Further included in the sunscreen composition is a microfluidized medium formulated and microfluidized separately and prior to blending with the other aforementioned components. This medium includes water, a phospholipid, and an organic sunscreen agent identical to that in the emulsion. The combination of identical sunscreen agents in different environments provides an overall increase in SPF for the overall sunscreen composition.
