Description

trans-2-Hexenyl Formate is a clear, colorless to pale yellow liquid ester with a powerful, fresh, green, fruity, and slightly waxy odor reminiscent of unripe fruit and apple skin. This high-impact flavor and fragrance ingredient is prized for its ability to impart natural, green top notes and enhance fruity nuances in complex compositions. It is primarily sought after by manufacturers in the flavor and fragrance (F&F) industry, as well as producers of personal care and household products seeking to create sophisticated, nature-identical sensory experiences.

Application

• Flavor Formulations: Used as a key component in creating and enhancing natural-tasting fruit flavors such as apple, pear, strawberry, melon, and tropical fruit blends for beverages, confectionery, and dairy products.
• Fragrance Compositions: Serves as a top note in perfumery for green, fruity, and fresh accords, commonly found in fine fragrances, soaps, shampoos, and detergents.
• Aroma Chemicals: Acts as a valuable building block in the synthesis of more complex aroma molecules and as a standard for quality control in F&F laboratories.
• Personal Care Products: Incorporated into lotions, creams, and deodorants to provide a fresh, clean, and natural scent profile.
• Household Products: Used in air fresheners, fabric softeners, and cleaning agents to impart pleasant, fruity-green odors.
