Super Spreadable Mineral Spray SPF 50

Hallstar
This water-in-oil SPF 50 sunscreen spray uses zinc oxide only to provide UV protection. It boasts excellent spray properties and a light skin-feel despite its relatively highZnO load. HallSens™ DIAS is the sole carrier in the oil phase, helping to achieve outstanding dispersibility. Super Spreadable Mineral Spray is stabilized with a single emulsifier—Olivem® 2090—and contains no high-melting-point materials. The cold-process formulation was subjected to in vitro analysis, delivering an SPF of approximately 54, PFA (PPD) 21, UVA1/UV = 0.84, and acritical wavelength of 376 nm.
