Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vehicle:
yes
Remarks:
50% w/w megaface F142-D

Test organisms

Test organisms (species):
other: Rainbow trout (salmo gairdneri)
Details on test organisms:
20 fish in each group

Study design

Test type:
semi-static
Water media type:
freshwater
Total exposure duration:
96 h

Test conditions

Hardness:
350 mg/l as CaCO3 (noted as slightly higher than recommended, but not considered to have had an effect)
Test temperature:
14 +/- 1°C
Dissolved oxygen:
>= 9.8 mg O2/l
Nominal and measured concentrations:
100 mg/l
Rebewed daily
Details on test conditions:
100 mg/l was the highest concentration that could be tested because of the very low solubility of the material in water and the toxicity of the vehicle at high contrations.
