This cold process sunscreen cream provides broad spectrum sun protection. The SolaStay® S1 (Ethylhexyl Methoxycrylene) in HallBrite® EZ-FLO TDX Plus mitigates the photocatalytic and reactive oxygen species-generating activities of the oxide. The HallBrite® BHB (Butyloctyl Salicylate) in HallBrite® EZ-FLO TDX Plus aids wetting and dispersion of the Titanium Dioxide and contributes to enhanced product feel. Olivem® 2020 is able to create an emulsion with a very rich texture, together with a light, non-sticky touch. When subjected to in vitro analysis, this formula delivered SPF ~30, PFA (PPD) ~10 performance with critical wavelength 379 nm.
