Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Toxicity towards the terrestrial compartment was not investigated experimentally. The test substance is not placed onto the market as a monomer and will be used in the production of polymeric products. Thus, the substance is chemically bound and neither direct nor indirect exposure to the terrestrial compartment is intended. Authentic QSAR modellings (OECD QSAR Toolbox v2.1) were performed to investigate the toxicity to soil macroorganisms, terrestrial arthropods and birds. These results are used in the chemical safety assessment of the substance. The endpoints toxicity to terrestrial plants and soil microorganisms are waived in accordance to REACH, Annex IX, section 9.4, column 2. Information about toxicity towards other above-ground organisms is not available and not required for a registration under REACH for this tonnage band.
The soil macroorganisms Criconemoides sp., Meloidogyne hapla, Meloidogyne javanica, Pratylenchus brachyurus, Meloidogyne sp., Meloidogyne incognita, and Hoplolaimus columbus were considered for the toxicity prediction, resulting in a NOEL of 3.04 AI kg/ha (AI = Active Ingredient) (Chemservice S.A., 2012). Regarding terrestrial arthropods the species Bombyx mori, Formicidae, Histeridae, Carabidae, Microplitis croceipes, Frankliniella sp., Apis mellifera, Lasius neoniger and Pediobius foveolatus are taken into account, giving a NOEL of 3.02 AI kg/ha as result (Chemservice S.A., 2012) and Japanese Quail (Coturnix japonica) served as representative to estimate the toxicity potential to birds, whereby a LC50 of 383 mg/L is reported in this case (Chemservice S.A., 2012).
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.
