Additional information

In accordance with column 2 of REACH Annex IX, the simulation testing on ultimate degradation in surface waters and sediment simulation testing does not need to be conducted if the substance is readily biodegradable or highly insoluble in water. As the substance is the salt of two components which are expected dissociate in water, both components are considered separately. One component is readily biodegradable, the other is highly insoluble in water.
