  • Applications

    Tricosanoic acid (CAS 2433-96-7) is a long-chain saturated fatty acid used primarily as a feedstock and building block for esters, waxes, and related derivatives. In cosmetics and personal care, its ester derivatives are used as emollients and thickening agents in creams and lotions. In polymers and plastics processing, it serves as a lubricity additive and as a basis for high-molecular-weight fatty esters that act as plasticizers or softeners for plastics and rubbers. In coatings and inks, it can be used to prepare wax-like additives and surfactant components to improve gloss and stability of emulsions. In cleaning and detergents, it provides a source of fatty acid for soap formation and can function as a co-surfactant or emulsifier in formulations. In industrial manufacturing, it is commonly used as an intermediate for esters and specialty lubricants.
