  • Applications

    12-Methylhexadecanoic acid (CAS 17001-24-0) is a branched long-chain fatty acid used primarily as an intermediate and additive across several industrial and consumer applications. In cosmetics and personal care, it serves as an emollient and as a precursor for esters and mild surfactants. In polymers and plastics, it is commonly employed as a lubricant or plasticizer for resins and PVC, improving processability and flexibility. In coatings and inks, it can function as a base oil or as an ester component to enhance slip and coating performance. In cleaning formulations, it may act as a precursor for surfactants and detergent components. It is also considered a potential intermediate for producing ester derivatives used in fragrance and other industrial applications, depending on local regulations.
