The acute toxicity of sucrose esters to fish was determined in an OECD
Guideline 203 study. Groups of seven fish were exposed to 0 or 100 mg/L
of sucrose esters for 96 hrs. Due to the complex nature of the test
substance, results were reported as water accomodated fraction (WAF). No
fish in the test or control groups died or showed abnormal behaviour.
The 96-hr LL50 is therefore >100 mg/L (WAF).
LL50 (96 h) > 100 mg/L (nominal, OECD 203)
One experimental study is available investigating the toxicity of
the test item to the freshwater fish Pimephales promelas. The study was
performed according to OECD 203 (GLP) under static conditions. Due to
the low water solubility the test solutions were prepared as Water
Accommodated Fractions (WAF) and the loading rate of 100 mg/L (nominal)
was tested. The WAF was prepared by adding an appropriate amount of test
item to test medium followed by mixing for 48 h and a settling time of 5
h. Since undissolved particles were present in the solution it was
carefully decanted to the exposure vessels in order to avoid undissolved
material in the test vessels. No evidence of precipitate was seen in the
test chambers. After exposure of 96 h no mortality was recorded
resulting in a LL50 (96 h) of > 100 mg/L based on the nominal loading
