Overview
Ethyl propionate (CAS 105-37-3 ), also known by FEMA 2456 , is a synthetic ester used primarily as a flavoring agent and fragrance ingredient across food and personal care manufacturing.
It delivers a characteristic fruity, rum-like odor profile that positions it as a building block in flavor and fragrance formulation. In food and beverage production, it contributes fruity top notes to confectionery and baked goods.
The compound is frequently utilized in dairy flavors and alcoholic beverage profiles. Fragrance formulators incorporate it into personal care products including lotions, shampoos, and body washes where its sweet character enhances scent.
It also functions as a carrier or co-solvent in cosmetic formulations, supporting the even dispersion of fragrance compounds. Flavor houses use it as a blending component to round out tropical and berry flavor systems.
These systems are often destined for soft drinks and processed foods. The product is supplied as a clear, mobile liquid in standard packaging ranging from drums to ISO tank containers for bulk industrial orders.
It is available in food-grade quality compliant with the FEMA designation, suitable for use in flavored product applications. Technical-grade material is also available for fragrance and cosmetic manufacturing needs.
This grade is ideal for applications where food compliance is not required. Our supply chain ensures consistent quality and reliable delivery for manufacturers requiring high-purity esters for their production lines.
