Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Experimental data on the toxicity of the substance to terrestrial organisms are not available. The substance is characterised by a high water solubility (WS 34.7 g/L at 19.8 °C (flask method, OECD 105) and a low log Koc (log Koc < 1.32, OECD 121). Based on the physico-chemical parameters of the substance partitioning to the water phase is expected if the substance is released to the environment. The substance is not readily biodegradable (9% after 28d). A QSAR calculationusing the Persistence (soil) model (IRFMN) 1.0.0, included in the VEGA software version 1.1.4, predicted “not P” for the substance. Furthermore, the release rates to wastewater during the lifecycle of the substance are negligible. The environmental exposure assessment for the substance indicates no risk for the terrestrial compartment (all RCR< 1; please refer to Chapter 9 and 10 of the Chemical Safety Report for detailed information). Thus, direct and indirect release of the substance to the terrestrial compartment is considered to be very low.
The substance is not readily biodegradable (9% after 28 d, OECD 301B), has a low potential for adsorption (log Koc < 1.32, OECD 121) and there is no indication that the substance is very toxic (EC/LC50 >1 mg/L). According to the information given in the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7c: Endpoint specific guidance (ECHA, 2017), the substance is assigned to soil hazard category 3. Thus a confirmatory long-term soil toxicity testing on soil macroorganisms is proposed.
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.
