Overview
Propyl propionate (CAS 106-36-5 ) is an ester solvent and flavoring agent used across coatings, personal care, and food applications. FEMA 2958 designation confirms its recognized status as a flavoring ingredient in food-grade contexts.
It delivers a fruity, rum-like aroma profile that supports its dual role in both industrial solvent systems and flavor formulations. In coatings and printing inks, it functions as a fast-evaporating solvent that improves flow and film formation.
This chemical improves film formation without leaving residue. Adhesive formulators use it as a carrier solvent to control viscosity and open time in solvent-based systems, ensuring consistent application and performance in industrial settings.
In personal care, it acts as a solvent and emollient carrier in fragrance compositions, nail care products, and aerosol formulations. Food and beverage manufacturers incorporate it as a flavoring agent to impart fruity, sweet notes.
These sweet notes are ideal for confectionery, beverages, and baked goods. Propyl propionate is supplied as a clear liquid in drum and IBC quantities for industrial buyers, with smaller packaging available for flavor and cosmetic applications.
It is available in technical grade for coatings and adhesive use, and in food-grade purity aligned with FEMA and flavor industry standards. Buyers should confirm purity specifications and regulatory compliance documentation when sourcing.
Particular attention should be paid to FCC certification when sourcing for food or cosmetic end uses. This ensures the material meets the rigorous safety and quality requirements necessary for consumer-facing products and global trade.
