Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 for terrestrial organisms.
Key value for chemical safety assessment
Additional information
In accordance with REACH Regulation (EC) 1907/2006, Annex IX and X, Section 9.4., Colum 2, the toxicity testing to terrestrial organisms shall be proposed depending on the results of the chemical safety assessment. According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as hazardous according to Regulation EC 1272/2008 and its second adaptation 286/2011 or is assessed to be a PBT or vPvB. The hazard assessment reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance, nor are there any further indications that the substance may be hazardous to the environment.
In addition, indirect exposure to soil is unlikely since the substance is readily biodegradable according to OECD criteria. For substances being considered as „readily biodegradable“, it can be assumed that they will be completely biologically degraded within the STP process. Indirect exposure to soil is not likely e.g. via agricultural use of sewage sludge since the test substance is readily biodegradable (see IUCLIC Ch. 5.2.1). Furthermore, for substances not passing the STP-process but being readily biodegradable, it can be assumed that they will be also biological degraded in the surface water within a short time. Direct exposure to soil is not likely since the substance is not intentionally applied to soil. For the substance only industrial and professional uses with adequate risk mitigating measures are foreseen. Environmental exposure through widespread uses by consumers is excluded.
The substance has no potential to bioaccumulate. Regarding the charged molecule at pH 7 the log Koc was estimated to be 1.62 following the method of Franco & Trapp, 2008, 2009, 2010 (BASF, 2021). Therefore, adsorption to solid soil phase is not expected (log Koc < 3).
In conclusion no testing is required.
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.
