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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
In Annex XI of Regulation (EC) No 1907/2006, it is laid down that there may be sufficient weight of evidence from several independent sources of information leading to the assumption/conclusion that a substance has or has not a particular dangerous property, while the information from each single source alone is regarded insufficient to support this notion. In the mentioned case further testing on vertebrate animals for that property shall be omitted. In this case the present substance was tested in short-term aquatic tests (algae, daphnia and fish). All None of the test showed acute or chronic toxic effects (aquatic invertebrates, algae). No adverse effects have been observed in acute studies at the highest recommended concentrations/doses tested, therefore, it can be concluded that all none of the test showed acute or chronic toxic effects (see IUCLID Ch. 6.1). In ECHA’s Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.11: PBT/vPvB assessment it is stated that information on molecular size can be an indicator to strengthen the evidence for a limited bioaccumulation potential of a substance. For consideration of its nano-material properties its particle size distribution was determined using Transmission Electron Microscopy (TEM) provided in Chapter 1.4. Based on these measurements, no particle found was smaller than 10 nm. This size is above the threshold of 1.7 nm given in ECHA’s Guidance document mentioned above. Taking this into account additional to the low logKow and the low octanol solubility, a transportation of the substance in its particulate nano form through biological membranes and a resulting toxic effect due to lacking exposure is unlikely.
Therefore, and for reasons of animal welfare a long-term toxicity test in fish is not provided.
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.
