Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Justification for type of information:
The present registration dossier contains all tonnage-driven data requirements for assessment, which include at this tonnage level all three trophic levels, and both acute and chronic data. So, the potential hazard of the substance to the aquatic environment, representative for the whole environment, can be sufficiently and reliably assessed. The available information triggers anyway classification as Aquatic Chronic 1, which is the most severe classification, which is followed by stringent safety measures. This leads also to the protection of terrestrial organisms. In addition, terrestrial organisms are not relevant for classification according to Regulation (EC) 1272/2008, and sufficient risk management measures are secured.
REACH Annex IX column 2 explicitly foresees that, in the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. This method allows to estimate also the PNECs for the soil and sediment compartment, and so all required information for risk assessment of the substance is given. Having a PECsoil/PNECsoil ratio < 1 for all exposure scenarios, there is no need to perform a toxicity test for terrestrial compartment as the risk towards terrestrial organisms is sufficiently controlled based on the already available information.
In consequence, testing can be omitted.
In addition, the substance is poorly soluble in water and has a medium tendency to adsorb on soil. The substance is therefore only slightly bioavailable and not available for plants as the need mobile substances.
