Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two studies are available that both lack sufficient detail to allow definitive conclusions. Under aerobic conditions degradation half life was 3.9-7.3 hours, while under anaerobic conditions the half live was 18.2 hours (Ward 1984). The study by Federle (1988) was performed on a column of 20 meters that is likely to have included both aerob and anaerob sections. Mass balance in this study was > 100% and the degradation half live was 0.84 day (ca 20 hours).
The results of these are also all consistent and show a half life of under 1 day. The highest half life is 0.84 days. Thus 0.84 days is justifiable to include this value within the EUSES.
Key value for chemical safety assessment
- Half-life in soil:
- 0.84 d
- at the temperature of:
- 20 °C
Additional information
No definitive conclusions were drawn, in view of the limitations of studies available.
The results of these are also all consistent and show a half life of under 1 day. The highest half life is 0.84 days. Thus 0.84 days is justifiable to include this value within the EUSES.
According to REACH Annex IX section 9.2.2.1 Column 2 this study can be waived if the test substance is readily biodegradable. Therefore as the substance is readily biodegradable, a waiver is justified.
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.
