Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
