Butyl propionate
Description
Butyl propionate (CAS 590-01-2), also identified under FEMA 2211, is an ester solvent and flavoring agent used across food, fragrance, and industrial coating applications. It delivers a fruity, apple-like aroma profile that makes it commercially relevant to flavor houses and fragrance blenders.
In industrial settings, it functions as a medium-evaporation solvent for resins and surface coatings. In food and beverage manufacturing, it is used as a flavoring ingredient to impart fruity top notes in confectionery, beverages, and baked goods.
Fragrance formulators incorporate it into personal care products, including lotions, shampoos, and fine fragrances, where its pleasant ester character contributes to top-note compositions. In the printing and packaging industry, it acts as a carrier solvent for inks and coatings.
This chemical supports resin dissolution and controlled evaporation rates on press. It also appears in nail care formulations and cosmetic solvents where moderate evaporation speed is a specific formulation requirement for the end product.
Butyl propionate is supplied as a clear liquid in drum and IBC quantities suited to industrial procurement volumes. Food-grade material is available in compliance with the FEMA 2211 designation for flavoring use in various food systems.
Technical-grade supply is standard for solvent and coating applications. This material meets the rigorous demands of industrial manufacturing while maintaining consistent purity levels for high-performance chemical processing and formulation needs.
