  • Applications

    2-Ethyldecanoic acid, CAS 2874-76-2, is a branched long-chain fatty acid primarily used as a building block in the synthesis of esters and derivatives for a range of industrial applications. It commonly serves as an intermediate in the production of lubricant basestocks and plasticizers for polymers and elastomers. In cosmetics and personal care, it may be used as a component in emollient esters or as a formulation solvent and viscosity modifier. In coatings and inks, it can function as a surface-active additive or plasticizer-compatible ingredient to improve mixing and stability. It also may be evaluated as a chemical feedstock for fragrance-related esters and for cleaning formulations, where its fatty-acid character can contribute to surfactant performance. Use is subject to local regulations and formulation limits.
