This water-in-oil, zinc oxide-only sunscreen cream provides SPF 15 sun protection without using organic UV filters. PEG-free Olivem® 2090 is the only emulsifier used in this cold process. BLUE Oléoactif® contributes anti-pollution and anti-blue light properties. Active emollient Sensolene® Light ET combines superior emolliency with antioxidant benefits. Moisturizing Biochemica® Sweet Almond Oil and structuring HallStar® Zinc Stearate are great agents within this W/O system. In vitro analysis suggests SPF ~ 17, PFA (PPD COLIPA 2011) ~ 7, UVA1/UV = 0.81, and critical wavelength 371 nm.
