Description

Isoamyl butyrate ( CAS 106-27-4 ), also known as isopentyl butyrate, is a synthetic ester used commercially as a flavoring and fragrance ingredient. It delivers a characteristic banana, pear, and tropical fruit profile. This profile makes it a go-to choice for flavor houses and fragrance compounders. FEMA 2060 status confirms its recognized safety standing for use in food applications across the global market. In food and beverage manufacturing, it is used to create or reinforce banana, pear, and tropical fruit notes in confectionery, beverages, baked goods, and dairy products. It is highly versatile for these uses. Fragrance formulators incorporate it into personal care products, including shampoos, body lotions, and soaps, where fruity top notes are required. It provides a consistent and pleasant aromatic experience. It also appears in functional flavor blends where a low-cost, stable ester is needed to anchor volatile top-note compositions. This stability is essential for maintaining the integrity of complex flavor profiles. Confectionery manufacturers sourcing banana-flavored coatings and fillings frequently specify it as a primary flavoring agent. Its reliability makes it a staple in large-scale industrial food production. Isoamyl butyrate is supplied as a clear liquid, typically in drum and IBC quantities for industrial buyers. It is available in food-grade and flavor-grade specifications aligned with FEMA and FCC standards. Technical-grade material is also available for fragrance and non-food applications where food compliance is not required. This ensures a range of options for different manufacturing and regulatory needs. Contact us for supply of Isoamyl butyrate Request Quote
