  • Applications

    Henicosanoic acid (CAS 2363-71-5) is primarily used as an intermediate and building block in chemical synthesis, with practical applications across cosmetics/personal care (as long-chain esters and conditioning agents), industrial lubricants and lubricant additives, household cleaning formulations (as a precursor for surfactants and emulsifiers), polymers and coatings (as a feedstock for long-chain polyesters, waxes, and resin modifiers), and coatings and inks formulations (as a waxy additive or plasticizer component).
