Results and discussion
Any other information on results incl. tables
According to the guideline, a substance is considered to be oxidizing when the burning rate of a mixture of the test substance and cellulose is higher or equal to the maximum burning rate of a reference mixture of cellulose and barium nitrate. The test substance is a mixture of the by-pro-ducts from the manufacture of 1,4-Benzenedicarboxylic acid, dimethyl ester.
Examination of the molecular structures of the products establishes beyond reasonable doubt that the test substance is incapable of burning, when mixed with cellulose, at a higher or equal rate compared with the maximum burning rate of a reference mixture of cellulose and barium nitrate. The products do not contain any group that might act as an oxidizing agent. The oxygen atoms that are present are all bonded to carbon, which indicates that the molecule is oxygen-deficient.
In conclusion, Terate®091 Residue has no oxidizing properties.
