Reference
Endpoint:
partition coefficient
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is inorganic

Description of key information

In accordance with column 2 of REACH Regulation 1907/2006/EC Annex VII section 7.8, the test on partition coefficient n-octanol/water does not need to be conducted if the substance is inorganic. Zinc cyanide is an inorganic substance, therefore this endpoint was waived.

Key value for chemical safety assessment

Log Kow (Log Pow):
-2.31
at the temperature of:
25 °C

Additional information

The theoretical, calculated (EPIWIN) log Pow is - 2.31, i.e. very low, as expected for an inorganic substance.

This value was used for CSA purposes.
