Description of key information

The n-octanol/water partition coefficient for the test substance, estimated using the EPISuite KOWWIN model, is log Kow18.94. The log Kowfor the fraction not containing molybdenum has a measured log Kowof greater than 5.65.


Additional testing is waived based on the inorganic nature of the test substance, the high predicted log Kow, and the low water solubility of the test substance.  

Key value for chemical safety assessment
