This zinc oxide-only, water-in-oil SPF 60 sunscreen spray uses non-nano zinc oxide to provide UV protection. It boasts excellent sprayability and a light skin feel despite its relatively high ZnO load. HallSens™ DIAS is the sole carrier in the oil phase, helping to achieve outstanding dispersibility. Mineral Mist SPF 60 is stabilized with a single emulsifier—Olivem® 2090—and contains no high-melting-point materials.
In vivo testing conducted in a U.S. laboratory (3 subjects) yielded a static SPF of 63.25. The cold-process formulation was also subjected to in vitro analysis, delivering an SPF of approximately 52, PFA (PPD) 22, UVA1/UV = 0.84, and a critical wavelength of 375 nm.
Shake well before use for better uniformity.
