Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A 96-h LC50 value of >16 µg/L has been determined for the effects of the test substance on mortality of Oncorhynchus mykiss under flow-through exposure conditions. A NOEC of ≥16 µg/L has been determined in the same test. Continuation of exposure to a total of 14 days resulted in the same values (Springborn Laboratories 2000). Very similar results (7- and 35-day LC50 values of >15 µg/L and NOECs of ≥15 μg/L) have been obtained in an equally reliable test with another species (Pimephales promelas, Dow Corning 2005a). The results of a third test conducted at treatment levels well above the solubility of the substance also showed an absence of effects on mortality following short-term exposure.
