Description

Isobutyl acetate (CAS 110-19-0), also known by its FEMA 2175 designation, is an ester solvent and flavoring agent used across food, cosmetic, and coating applications. It delivers a characteristic fruity, pear-like aroma that makes it commercially valuable in both flavor formulation and fragrance blending for various consumer products.

In food and beverage manufacturing, isobutyl acetate is used as a flavoring ingredient to impart pear, apple, and tropical fruit notes in confectionery, beverages, and baked goods. Cosmetic and personal care formulators incorporate it as a fast-evaporating solvent in nail lacquers, perfumes, and aerosol products where clean dry-down is required for the user.

It also functions as an industrial solvent for nitrocellulose lacquers, printing inks, and surface coatings, where its moderate evaporation rate supports film formation and flow. In fragrance compounding, it serves as a carrier and modifier to adjust the volatility profile of finished blends, ensuring consistent performance across different applications.

Isobutyl acetate is supplied as a clear liquid in drum and IBC quantities. Food-grade material conforming to FCC and FEMA 2175 specifications is available for flavor use. Technical-grade product is offered for industrial solvent use in coatings and inks, providing a reliable solution for manufacturers requiring high-purity chemical components.
