  • Applications

    Decanoic acid, 2-methyl-, CAS 24323-23-7, is a branched fatty acid used as a versatile building block in industrial synthesis. It is commonly employed as an intermediate for the production of branched fatty acid esters used in fragrance and flavor applications, and as a precursor for surfactants and detergent components to improve cleaning performance. It also serves as a feedstock for plasticizers and lubricant additives in polymer processing, and can function as a resin modifier or slip additive in coatings and inks. In cosmetics and personal care, it can act as an emollient or conditioning ingredient in formulations. Its use is typically as an intermediate or building block, and applications are subject to local regulations and formulation limits.
