  • Applications

    Maltyl isobutyrate (CAS 65416-14-0) is a specialty flavoring ester with a distinctive malty-caramel nuance that enriches bakery goods, breakfast cereals, chocolate, instant coffee, nutritional drinks, non-alcoholic beer and carbonated soft beverages, while also finding use in e-cigarette liquids, toothpastes, sports nutrition powders and animal feed where it masks metallic off-notes, prolongs sweetness, resists thermal degradation and lends a fresh, rounded palate; in perfumery and cosmetic formulations it serves as a warm bready-toffee base note that harmonizes fruit or woody accords, increases compositional complexity and extends the lasting power of fragrant oil blends.
