Clinical sun care brand myDerm has picked Honeywell’s Solstice Propellant (HFO-1234ze) in its latest broad-spectrum sunscreen, Mineral SPF 50 Clinical Sunscreen Continuous Spray.
Solstice Propellant is a ready-now, non-ozone depleting hydrofluoroolefin (HFO) solution that has an ultra-low-global-warming-potential of less than one.
The propellant helps reduce greenhouse gas (GHG) emissions by 99% compared with alternatives commonly used in aerosol products.
"At myDerm, it is all about the ingredients we use to create our clinical strength sun and skin care products that our customers can trust,” said Diana Alderson, vice president of marketing, myDerm.
"Our newest sunscreen is not only dermatologist-recommended, but also Hawaii-approved with the highest formulation standards. This new formula is free of isobutane, oxybenzone, octinoxate and parabens, and the incorporation of Honeywell’s Solstice Propellant also enables us to help protect people without sacrificing performance or impact on the environment.”
Solstice Propellant is also volatile organic compound (VOC)-exempt — per the US EPA and California Air Resources Board (CARB) — meaning it has negligible contribution to ground-level smog formation.
This allows formulators to reduce the use of VOC ingredients like hydrocarbon propellants, particularly in continuous spray sunscreen applications.
