Propyl acetate

Propyl acetate (CAS 109-60-4), also known by its abbreviation NPAC, is an ester solvent and flavoring agent used across printing, personal care, and food industries. It dissolves a broad range of resins, coatings, and fragrance materials, offering a moderate evaporation rate that suits both industrial solvent applications and sensory formulation work.

In printing and packaging, NPAC is used as a carrier solvent in flexographic and gravure inks, where its evaporation profile supports print quality and press-speed requirements. Personal care formulators incorporate it into nail care products, hair sprays, and perfume bases as a solvent and diluent for film-forming resins and fragrance concentrates.

In food and beverage manufacturing, it functions as a flavoring ingredient — FEMA 2925 — contributing fruity, pear-like top notes to confectionery, beverages, and baked goods. It also serves as a process solvent in flavor extraction and concentration operations. Propyl acetate is supplied as a clear liquid in drums, IBCs, and bulk tanker quantities.

Technical grade is standard for industrial solvent applications, while food-grade material meeting FCC specifications is available for flavor and food processing use. Purity levels of 99% and above are typical across commercial supply. This versatile ester remains a staple for manufacturers requiring reliable solvency and aromatic properties.
