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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Readily biodegradable according to OECD criteria: 100% after 28 days (OECD 301 B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of C12-16AS Na (CAS 7329-89-6) was investigated in a GLP guideline study according to OECD 301 B (Clarke 2005). Domestic, activated and non-adapted sludge was used as inoculum. After 28 days of exposure the biodegradation measured as CO2 evolution reached 100%; the substance is therefore considered as readily biodegradable.
The supporting test was performed according to Annex 1 of ECETOC report nr 28. This anaerobic biodegradation study demonstrated that 63.3% of the test substance is mineralised to CO2 within 35 days of exposure (Richterich, 2003).
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.
