  • Applications

    14-Methylpentadecanoic acid (CAS 32844-67-0) is a long-chain branched fatty acid that may be used as a building block for branched esters in fragrance and cosmetic ingredients; it may also serve as a component in personal care formulations as an emollient, a precursor to surfactants, or a wax-like additive. It is often evaluated as a starting material for surfactant blends and cleaning formulations in household products. In polymers and plastics, it can be used as a lubricant base stock or plasticizer and as a processing aid for polymer manufacture. In coatings and inks, it may act as a hydrophobic modifier or wax additive to enhance gloss and water resistance. In industrial manufacturing, it serves as an intermediate for ester synthesis and specialty additives, subject to regulatory and formulation constraints.
