99% Dilauryl Thiodipropionate

Chemical Properties:

The density is 0.915, and the melting point is 39-40°C. Soluble in benzene, toluene, acetone, gasoline and other solvents. Has the effect of decomposing peroxides. It can be used as auxiliary antioxidant for polyethylene, polypropylene, ABS resin, polyvinyl chloride, etc. It has the characteristics of no pollution, no coloring, and no decomposition during high temperature processing.


  1. Fat-soluble antioxidants. my country’s “Hygienic Standards for the Use of Food Additives” (GB2760-1996) stipulates that dilauryl thiodipropionate can be used for edible oils, fruit and vegetable preservation, and oil-containing foods, and its maximum use amount is 0.2g/kg (calculated by fat content) ). Other reference for use: For the fresh-keeping soaking liquid of fruits and vegetables, the use limit is 0.2g/L; for the anti-oxidation of animal and vegetable oils, the use limit is 0.2g/L. As a fat-soluble antioxidant, this product can be used in animal and vegetable oils. The use of a separate Chemicalbook is not as effective as propyl gallate, butylated hydroxyanisole, and dibutylated hydroxytoluene. Should be used in combination with other fat-soluble antioxidants. The representative varieties of organic disulfide auxiliary antioxidants are dilauryl dipropionate sulfide (DLTP) and distearyl thiodipropionate (DSTP). Dilauryl thiodipropionate has the function of decomposing hydroperoxides. Dilauryl thiodipropionate has the characteristics of no pollution and no coloring as a polyolefin auxiliary antioxidant. Dilauryl thiodipropionatehas the characteristics of synergistic effect when used with phenolic antioxidants. Dilauryl thiodipropionatehas low toxicity and can be used for food packaging and agriculture, usually in the amount of 0.05 to 1.5 parts.
  2. As an antioxidant, Dilauryl thiodipropionate can be used as an antioxidant for oily foods and edible oils and as a preservative for fruits and vegetables. The maximum use amount is 0.2g/kg.
  3. Used as an auxiliary antioxidant, widely used in polypropylene, polyethylene and ABS resins, and can also be used in rubber processing lubricating greases
  4. Dilauryl thiodipropionate can be widely used in synthetic materials such as polyethylene, polypropylene and ABS, PBT, and can also be used in rubber processing and lubricating grease
  5. White flake-like crystalline solid. Insoluble in water, soluble in acetone, carbon tetrachloride, benzene, petroleum ether and other organic solvents. The solubility (g/100g solvent) in various solvents at 20°C is: acetone 20; carbon tetrachloride 100; benzene 133; petroleum ether 40.
