Description

5-Decanolide is a high-purity lactone compound, also known as δ-decalactone, valued for its characteristic creamy, peach-like aroma and flavor. This versatile intermediate is essential for creating complex organoleptic profiles in fine fragrances and high-value food products. It is a critical raw material for flavor and fragrance houses, as well as specialty chemical manufacturers in the personal care and pharmaceutical sectors.

Application

• Flavor & Fragrance (F&F) Industry: A key ingredient for imparting creamy, coconut, and peach notes in premium perfumes, cosmetics, and fine fragrances.
• Food & Beverage Flavors: Used as a flavoring agent in dairy products (e.g., cream, butter), confectionery, and beverages to enhance creamy and fruity flavor profiles.
• Synthetic Intermediates: Serves as a valuable chiral building block in the synthesis of more complex molecules for pharmaceutical and agrochemical research.
• Personal Care Products: Incorporated into lotions, creams, and soaps for its pleasant fragrance and potential emollient properties.
• Aroma Chemicals Production: Used in the manufacture of other macrocyclic and aliphatic lactones for expanded aroma chemical applications.
