Key value for chemical safety assessment

Additional information

Testing for sediment toxicity is not considered necessary because:

- The substance hydrolyses rapidly in contact with water and the Log Kow of the hydrolysis product is <3.

- The substance is used under highly controlled conditions and, therefore, exposure of sediment is low.

- PNECsediment has been calculated from PNECfreshwater on the basis of the equilibrium partitioning method; the risk characterisation ratios (RCR) based on PNECsediment derived from this method are <1.
