Dusting Analysis
Propyl Propionate is valued for its functional contributions as a solvent and fragrance in formulations, rather than being promoted for direct active skincare benefits.
The Formula
Formulation
Stability
Propyl Propionate is a volatile ester with a low flash point of -19°C. It exhibits low water solubility at approximately 5 g/L at 15°C, but is miscible with organic solvents like ethanol and ether, and effectively dissolves grease, wax, and resin. No specific optimal pH range for its stability has been determined.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that alkyl esters, including Propyl Propionate, are safe in cosmetic products when formulated to be non-irritating. It is important to differentiate this from Propylparaben, as SCCS opinions often pertain to the latter. The FDA lists Propyl Propionate as Generally Recognized As Safe (GRAS) for use as a flavoring agent in food.
