Dilauryl thiodipropionate Usage And Synthesis

Appearance	White to Almost white powder to crystal
Uses	Dilauryl Thiodipropionate (DLTDP) is an antioxidant that exists as white crystalline flakes of sweetish ester-like odor. It is insoluble in water but soluble in inorganic solvents. It is used in fats and oils to prevent rancidity. It is used in food when the total antioxidant content is not over 0.02% of the fat or oil content.
Uses	Didodecyl 3,3'-Thiodipropionate is an antioxidant used as a modifier to stabilize acrylonitrile-butadiene-styrene (ABS) graft copolymers due to a strong synergistic effect. This substance is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing.
Uses	Didodecyl 3,3''-Thiodipropionate is an antioxidant used as a modifier to stabilize acrylonitrile-?butadiene-?styrene (ABS) graft copolymers due to a strong synergistic effect.
Flammability and Explosibility	Nonflammable
Safety Profile	An eye irritant. When heated to decomposition it emits toxic fumes of SOx.
