Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
No data available
Key value for chemical safety assessment
Additional information
No studies on terrestrial arthropods are available for the substance. In Annex X section 9.4 of Regulation (EC) No 1907/2006, it is laid down that tests on terrestrial organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on terrestrial organisms. The choice of the appropriate tests depends on the outcome of the chemical safety assessment. In particular for substances that have a high potential to adsorb to soil or that are very persistent, the registrant shall consider long-term toxicity testing instead of short-term. According to Annex X section 9.4 of Regulation (EC) No 1907/2006, those studies do not need to be conducted if direct or indirect exposure of the soil compartment is unlikely. The available data indicate that the substance is not very adsorptive (log Koc < 3; see IUCLID chapter 5.4.1) or bioaccumulative (mean BCF = 0.45; measured, see IUCLID chapter 5.3.1). Furthermore, the substance’s distribution modelling indicates that the main target for environmental distribution will be water (see IUCLID chapters 5.4.2 and 5.4.3). Therefore, exposure of terrestrial organisms is unlikely. In addition, the substance is not a PBT or vPvB substance. Furthermore, there are already test data on terrestrial organisms (plants) available (Reynolds T., 1989; see IUCLID chapter 5.2.1). Consequently, no test on terrestrial arthropods is performed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
