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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Biodegradation
Biodegradation in water: screening test:
The test substance was examined for ready biodegradability according to the national German Standard DIN 38409, Part 43 equivalent to OECD 301 A and OECD 302 B (Inherent biodegradability: Zahn-Wellens test). The test substance was shown to be ready biodegraded by an average of < 10 % and inherently biodegraded by an average of 80 - 90 % over the test period of 28 days. Thus, the test substance was found to be not ready biodegradable but inherently biodegradable according to OECD criteria under the test conditions.
Hydrolysis
According to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), the test substance is generally resistant to hydrolysis because it does not contain any labile functional groups. Therefore, no study on hydrolysis is performed.
Bioaccumulation
No studies are available for the bioaccumulation assessment of the test item. The log Pow was calculated to be clearly below 3. Regarding this value, accumulation of the test substance in organisms is not to be expected. Therefore, and for reasons of animal welfare, a study on bioaccumulation is not provided.
Transport and distribution
Adsorption/desorption
In accordance with REACH Annex VIII column 2, the study does not need to be conducted as the substance has a low potential for adsorption (the substance has a low n-octanol/water partition coefficient: log Pow =1.2).
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.
