This daily wear ZnO sunscreen cream provides SPF 60 protection without using organic UV filters. PEG-free Olivem® 2090 is the sole emulsifier in its cold-process W/O emulsification. HallStar® C1215 Alkyl Benzoate Natural provides good dispersing action for ZnO powder. The addition of Hallstar Beauty’s SolaPure™ Glo enhances sunscreen efficacy and contributes moisturizing and antioxidant properties. In vitro analysis suggests SPF ~ 62, PFA (PPD COLIPA 2011) ~ 18, UVA1/UV = 0.80, and critical wavelength 372 nm.
