Sunscreen Lotion SPF 30

This formulation was designed to provide superb broad spectrum (SPF/PFA <<3), UVA/UVB 5 stars, label SPF 30 performance. SolaStay® S1 provides very rapid and efficient excited state quenching of Avobenzone, protecting it from photodegradation, and also mitigates the photocatalytic and reactive oxygen species generating activities of Titanium Dioxide to improve sunscreen performance. HallBrite® BHB contributes to UV filter solubility and enhanced product feel. This formulation was subjected to in vitro analysis and delivered SPF ~32 , PFA (PPD) ~18 performance with critical wavelength 380 nm (UVA/UVB 0.91 – 0.86).
