  • Applications

    8-Methyldecanoic acid (CAS 5601-60-5) is a branched long-chain fatty acid commonly used as a chemical intermediate and building block in the synthesis of specialty esters and surfactants. It can serve as a basis for lubricant and plasticizer formulations in polymers and coatings, contributing to flexibility and processability. In cosmetics and personal care, it may be employed as a fatty acid emollient or as a feedstock for ester derivatives. In cleaning and household products, it can function as a fatty acid based surfactant or as a precursor for surfactant components. It is also evaluated as an intermediate for agrochemical adjuvants or formulation additives, with use limited by regional regulations and formulation constraints.
