  • Applications

    2-Methylpentadecanoic acid is a branched, long-chain saturated fatty acid that is commonly used as an intermediate for the synthesis of specialty esters and surfactants, including components for detergents and cleaners. It serves as a lubricant or plasticizer precursor in industrial manufacturing and as a modifier in coatings and inks formulations. In cosmetics and personal care, it can be converted to emollient esters and conditioning agents. It is also used as a building block in polymer and plastics formulations, where branched fatty-acid esters contribute to performance. Use is formulation- and regulation-dependent, with salts or derivatives positioned for specific cleaning, surfactant, or additive applications.
