Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Hydrolysis
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, Section 9.2.2.1., no study on hydrolysis needs to be conducted, if the substance is readily biodegradable. Since the ready biodegradability of the test substance was proven (please refer to IUCLID section 5.2.1), an experimental investigation of its hydrolytic properties was not considered necessary.
Biodegradation
Biodegradation in water: screening test
The ready biodegradability of the test substance was examined according to the OECD 301 B (CO2 evolution, modified Sturm test). The test substance was degraded 80 - 90 % CO2/ThCO2 at the end of the ten-day window and 90 – 100 % DOC at the end of exposure. The test substance was found to be readily biodegradable under the test conditions and the required pass level for ready biodegradability within a ten days window was reached.
Transport and distribution
Adsorption/desorption
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, Section 9.3.1, a study on adsorption/desorption does not need to be conducted, if the substance and its relevant degradation products decompose rapidly. Since the ready biodegradability of the test substance was proven (please refer to IUCLID section 5.2.1), an experimental investigation on adsorption/desorption was not considered necessary. In addition in accordance column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, Section 9.3.1, a study on adsorption/desorption does not need to be conducted, if based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient). Since the test item has a low octanol water partition coefficient of 0.5 an experimental investigation on adsorption/desorption was not considered necessary.
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.
