Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- inherently biodegradable
Additional information
Two aerobic degradation tests for the group of tocopherols and tocopheryl acetates available: One tests was performed with DL-alpha-tocopherol (CAS: 10191-41-0) a stereo according to OECD 301 F protocols and GLP. The test reveals a result of 70 -80% with an extended exposure up to 67d (Givaudan Suisse SA,2011).
A degradation test is further available for DL-alpha-tocopheryl acetate (CAS: 7695-91-2). In an OECD 301C test run over 39days, the biodegradation recorded was 30-40% (BASF,1988b).
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.
