Description of key information

In absence of experimental data the half-life as well as the degradation rate constant with hydroxyl radicals of Benzoguanamine has been estimated by using the software AOPWIN 1.92a.

Key value for chemical safety assessment

Half-life in air:
2.9 d
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

Based on the low vapour pressure of Benzoguanamine the atmosphere can be considered as minor pathway. This assumption is also supported by the Mackay-III-simulation. However, a QSAR estimation for the atmospheric life-cycle of Benzoguanamine has been performed showing a readily degradability by reaction with atmospheric hydroxyl radicals.
