  • Applications

    Disulfide, dioctadecyl (CAS 2500-88-1) is a long-chain organic disulfide with two octadecyl groups linked by a disulfide bond; in perfumery it is used as a fragrance fixative to improve scent longevity; in cosmetics/personal care it can act as a texture modifier and thickener in waxy formulations; in industrial lubricants and metalworking fluids it serves as a lubricity or friction-modifying additive; in coatings and inks it is used as a wax-like component to adjust gloss, slip, and water resistance; and in polymers/plastics processing it may function as a processing aid to facilitate handling and extrusion.
