Ingredient disclosure

Comments1 5 : This product is generally commercialized with an inhibitor. Therefore, the health hazard classification could be different, according to the inhibitor used and its concentration. The physical hazard classification considers the product as inhibited. However, under certain conditions (e.g. depletion or absence of the inhibitor) a hazardous polymerisation may occur.
