  • Applications

    cis-7-Hexadecenoic acid, CAS 2416-19-5, is primarily used as an oleochemical feedstock and chemical intermediate for the production of fatty acid esters. These esters are used in cosmetics and personal care as emollients and surfactant components, and in household and industrial cleaning formulations. The acid can serve as a base for biobased lubricants and lubricant additives. It also functions as a precursor or comonomer for biobased plasticizers and polymer additives used in coatings and inks.
