  • Applications

    Triacontanoic acid (CAS 506-50-3) is a long-chain saturated fatty acid used as a building block for the production of wax esters and lubricants; in cosmetics and personal care it serves as a precursor for emollient esters and wax-based ingredients; in industrial manufacturing it provides feedstock for specialty lubricants and wax formulations; in coatings and inks it can act as a waxy additive to improve slip, gloss, and water resistance; in cleaning formulations its salts may function as surfactants or be used to derive surfactants for specialty cleaners; in agriculture it can serve as an adjuvant or surfactant component in pesticide formulations to improve spreading and adhesion; in pharmaceuticals it may be employed as a lipid-like excipient or starting material for lipid-based drug delivery systems. Subject to local regulations and formulation limits.
