Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 to Salmo gairdneri  (rainbow trout) is >9.9 mg/L in an OECD 203 test under GLP (Reliablity 2) based on active ingredient concentration.

Key value for chemical safety assessment

Effect concentration:
9.9 mg/L

Additional information

The toxicity of the sodium salt of 2-sulfoethyl ester of coco fatty acid to fresh water fish has been assessed in three reliable with restrictions tests. In all three tests precipitation occured during the test. In one test where rainbow trout were semi-statically exposed to nominal concentrations of 0, 3.2, 10 and 100 mg/L, the exposure concentrations were quantified. The observed 96h LC50 in this test is >16.5 mg a.i./L based measured initial test concentration and > 9.9 mg a.i./L based on geometrical mean measured test concentration. This value of 9.9 mg a.i./L is as a worst-case used for risk assessment and C&L.
