  • Applications

    cis-9,cis-15-Octadecadienoic acid (CAS 18402-92-1) is used as a fatty acid feedstock and intermediate for the synthesis of fatty acid esters and soap-type surfactants for detergents and cleaners; it also serves as a raw material for cosmetic formulations as an emollient and conditioning agent; in coatings and inks, it is used to synthesize alkyd resins and drying oils; it is also used as a precursor for plasticizers and lubricant additives in polymer processing; and it can be a building block for oleochemical derivatives and specialty surfactants and functional esters.
