Uses

Different sources of media describe the Uses of 123-28-4 differently. You can refer to the following data:
1. 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.
2. 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.
3. 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
