Description of key information

Waiving of Test:
In accordance with column 2 of REACH Annex IX, simulation testing on biodegradation in water and sediment (required in section 9.2.1.2 and 9.2.1.4) does not need to be conducted as direct or indirect exposure of the aquatic and terrestrial compartments for this substance are unlikely. The substance is hydrolysed rapidly in a few minutes to the corresponding dicarboxylic acids. In addition based on the intended uses, exposure of soil towards tetrahydromethylphthalic anhydride is not likely.
