Other Information
There is a possibility that bicyclic phosphates or phosphites can be produced as a result of the thermal decomposition of the product when in combination with trimethyl propane derived products or their corresponding thimethyl alkane homologs. Bicyclic phosphates and phosphites are a class of material with acute neurotoxic properites which produce characteristic convulsive seizures in test animals. Therefore, this product should not be used in conjunction with trimethyl propane or trimethyl propane derived products.
