Science
Mechanism of Action
Functioning as a low molecular weight alkane, Propane facilitates product expulsion from aerosol containers by acting as a compressed gas. Its inherent volatility leads to immediate dissipation upon discharge, significantly minimizing direct dermal exposure.

Safety
Safety Profile
Extensive regulatory reviews confirm Propane's safety for cosmetic use. The CIR Expert Panel reaffirmed its safety in 2023 under current practices of concentration and use, building on conclusions from 2002. The FDA recognizes Propane as Generally Recognized As Safe (GRAS) for direct food substances. European regulations permit its use, provided impurities like butadiene are below 0.1%. Dermal toxicity is not a significant concern due to its extremely rapid evaporation and minimal skin contact, typically under 10 seconds. While high occupational concentrations (4000 ppm) have shown neurotoxic endpoints in rats, this is not relevant to cosmetic exposure levels.
