Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
-
The test material has been determined to be essentially insoluble in water.
-
The test material is a mixture; the test is not appropriate for mixtures.
No determination was possible according to Method C7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004 for the following reasons:
An assessment of hydrolytic stability was attempted using the computer-based estimation software, HYDROWIN, version 2.00, © 2000 US Environmental Protection Agency. However, the software could not estimate the rate constants for the test material.
Ready biodegradation studies have shown that the material does degrade by abiotic means i.e. hydrolysis, although the rate of hydrolysis is not provided by these studies.
The test item attained 20% degradation after 28 days and therefore cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No 301B. In the OECD 302C Inherent Biodegradability: Modified MITI Test (II) the percentage biodegradation at the end of the test by BOD were 0%. At the end of the test, the abiotic degradation rate of the test substance was 91.7%, so it's of little importance to calculate the primary biodegradation according to the residual content of test substance.
The substance has a log Pow value of 6.58. However investigation of bioaccumulation in a flow through experiment provided the following results:

The test substance is considered not to be highly bioaccumulative based on the above results.
Reliability
The above studies have all been ranked reliability 1 according to the scoring system of Klimisch et al (except for the HYDROWIN prediction which is assigned a reliability of 2). This ranking was deemed appropriate because the studies were conducted to GLP and in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of relevant results.
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.
