  • Applications

    2-Hexyldecanoic acid (CAS 25354-97-6) is a branched long-chain fatty acid commonly used as a chemical intermediate for the synthesis of fragrance esters and cosmetic ingredients, supporting perfumery and personal care formulations. It is evaluated as a precursor for surfactants and detergent components, and for producing specialty esters used in cleaning products and household formulations. It can serve as a plasticizer and surface-modifying additive in polymers and coatings, helping adjust flexibility and coating flow. It may be employed as a lubricity modifier in certain industrial lubricants or as a component in lubricant formulations for plastics processing. Its derivatives can also be explored for use in coatings, inks, and polymer blends as functional additives. Applications should be pursued under appropriate regulatory constraints.
