Description:
This Broad Spectrum SPF 30 Sunscreen Cream provides broad spectrum (SPF/PFA =3) performance. SolaStay® S1 is incorporated to rapidly and efficiently quench the excited states of avobenzone, protecting it from photodegradation and so improving 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) ~13 performance with critical wavelength 377 nm.
