Two underutilized OTC Category 1 sunscreen actives include ensulizole and sulisobenzone. Downfalls of these water-soluble actives are crystallization when falling out of solution and tendency to wash off the skin. Zemea® propanediol is a high performing solvent, leading to greater efficacy of these actives. The addition of Zemea® propanediol in a broad spectrum moisturizer or suncare product not only helps actives perform to their full potential, but improves the aesthetics of the formulation. It is non-irritating, provides increased moisturization, and excellent sensory characteristics.
