Description of key information

The estimated half-life for indirect photolysis of diethylenetriamine reaction with hydroxyl radical is 2.6 hrs.

Key value for chemical safety assessment

Additional information

The estimated half-life of 2.6 hrs. (0.11 days) is based on an assumed hydroxyl radical concentration of 500,000 molecules/cm3 and 24 hour photoday.
