Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests

Description of key information
The biodegradability of octane-1-thiol has been read across from tert-dodecanethiol. The results of the biodegradation test for tert-dodecanethiol indicate that the substance is not readily biodegradable. Oxygen consumption in vessels containing tert-dodecanethiol was negligible, indicating that it was not readily degradable under the conditions of the test.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradability of octane-1-thiol has been read across from tert-dodecanethiol. Jenkins (1990) is a GLP-compliant, closed bottle ready biodegradability study, with reference compounds, testing oxygen consumption, which follows OECD guideline 301D. Oxygen consumption in vessels containing tert-dodecanethiol was negligible, indicating that it was not readily degradable under the conditions of the test.
Data are also available for octane-1 –thiol from Thiebaud (1994), who carried out a closed bottle biodegradability test following OECD guideline 301D. However, only a summary of the study is available, and therefore the study cannot be fully evaluated. Although the conclusion states that octane-1 -thiol is not readily biodegradable, there is no data provided for octane-1 -thiol in the summary.
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.
