6,10,14-Trimethylpentadecan-2-one, commonly known as hexahydrofarnesyl acetone, is a synthetic ketone with a long, branched aliphatic chain. It is a colorless to pale yellow liquid with a characteristic fatty, waxy, and slightly floral odor reminiscent of iris and violet. This compound is primarily used as a fragrance ingredient and a flavoring agent. In perfumery, it serves as a fixative and contributes to the dry, powdery, and woody notes in fragrance compositions for cosmetics, soaps, detergents, and household products. As a flavoring substance, it imparts fatty, green, and waxy nuances to food products. Hexahydrofarnesyl acetone is considered a safe ingredient when used within established concentration limits in fragrance and flavor formulations. It is stable under normal conditions and compatible with a wide range of other cosmetic and food ingredients.
