Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The 96h-LC50 of DL-Alpha-Tocopheryl acetate a precurser to DL-Alpha-Tocopherol towards Rainbow trout (Oncorhynchus mykiss) was > 11 mg/l (measured) and thus clearly above the limit of water solubility.

Key value for chemical safety assessment

Additional information

The data refer to DL-Alpha-Tocopheryl acetate a precursor of DL-Alpha-Tocopherol. The toxicity of DL-Alpha-Tocopheryl acetate towards Rainbow trout (Oncorhynchus mykiss) was tested according to OECD Guideline 203 under GLP conditions with a limit test in a static test system (Schlienger, 1995). The measured 96h-LC50 was > 11 mg/l and thus clearly above the limit of water solubility. In a static test system established following German standard DIN 38412, part 15 testing the toxicity of DL-Alpha-Tocopheryl acetate to Leuciscus idus a nominal LC50 of >10000 mg/l was recorded after 96 hours (BASF AG, 1988).
