  • Applications

    5-Tetradecenoic acid is used as a versatile feedstock and intermediate for the synthesis of fatty acid esters across industries. In cosmetics and personal care, it is converted to emollient esters and other specialty derivatives. In perfumery and flavor applications, its unsaturated aliphatic chain enables production of fragrance ingredients and fixatives. In polymer and coatings chemistry, it serves as a building block for polyester resins and plasticizers used in coatings and adhesives. In cleaning and detergents, its esters may act as surfactant precursors and formulation aids. It can also be evaluated as a starting material for specialty lubricants or agricultural adjuvants, all subject to local regulations and formulation limits.
