Description of key information

Hydrolysis has been determined under different pH-conditions and under different temperatures. 
At the most relevant temperature (22°C) the hydrolysis half-life was 5 days at pH7, and 3 day at 30°C at pH 7, and 1 day at 60°C at pH 7

Key value for chemical safety assessment

Half-life for hydrolysis:
5 d
at the temperature of:
295.15 K

Additional information

The tests were performed according to OECD guideline 111, without any solvents.

The data show that hydrolysis is rapid at all three pH values tested (4, 7, 9), and the results show that the expected hydrolysis products were generated, namely, dihydroxy-TGIC, tetrahydroxy-TGIC and hexyhydroxy-TGIC.

Thus hydrolysis plays an important role in detoxification of TGIC in the environment
