Description: Protect and soothe your skin with this SPF-20 sprayable sunscreen. This non-greasy sunscreen has a uniquely dry afterfeel, thanks to the cyclomethicone-like skinfeel of Schercemol 105 ester and additional emolliency from Hydramol PGPD ester. Pemulen TR-2 polymeric emulsifier stabilizes this milky formulation while maintaining sprayable flow characteristics. Furthermore, Pemulen TR-2 polymeric emulsifier eliminates the need for tedious HLB calculations.
