Description of key information

A log Pow value of 5.98 was estimated by calculation. 

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

Given by the reactivity of 4,4'-MDI / DPG in the aquatic environment and its transient existence in water, the log Pow has little direct relevance to 4,4'-MDI / DPG's environmental fate, intermedia transport and ecotoxicity. For this reason a mesurement is not possible and a calculated value is provided.
