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 co-antioxidants are dilauryl dipropionate sulfide (DLTP) and distearyl thiodipropionate (DSTP). It has the function of decomposing hydroperoxides. It has the characteristics of no pollution and no coloring as a polyolefin auxiliary antioxidant. It has the characteristics of synergistic effect when used with phenolic antioxidants. It has low toxicity and can be used for food packaging and agriculture, usually in the amount of 0.05 to 1.5 parts.
