Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

An acute fish test was carried out in a flow-through system according to a method similar to OECD203. No analytical measurements were performed. However, as the test was set up as flow-through, the test concentrations are kept stable. Furthermore, as the test substance is assumed to have a high water solubility, the actual test concentrations and nominal concentrations are deemed comparable. The 96h-LC50 of TMAC was determined to be 462 mg/L, based on nominal concentrations.
