Description of key information
At the limit concentration of 1.30 mg/L of the test item, which corresponds to the geometric mean measured concentration of 0.785 mg/L, no effects were observed on Daphnia magna in the key study.
Both supporting studies shows that there is no toxic effects up to the water solubility.
Key value for chemical safety assessment
Additional information
Key study:
In the acute immobilization test withDaphnia magna(STRAUS) the effects of the dispersion with the nominal concentration of 1.30 mg/L of the test item, using methanol as solvent, were determined according to OECD 202 (2004). The limit test was conducted in sealed glass flasks without headspace under semi-static conditions over a period of 48 h from 2013-01-22 to 2013-01-26, with the definitive exposure phase from 2013-01-23 to 2013-01-25, at Dr.U.Noack-Laboratorien,Käthe-Paulus-Str. 1,31157 Sarstedt, Germany .
The concentration of 1.30 mg/L represents the maximum solubility level of the main component 2-(Perfluorooctyl)ethyl acrylate (water solubility: 0.7 mg/L, nominal content: 54.0 %). A solvent control containing dilution water spiked with 0.1 mL methanol/L was tested additionally. Twenty daphnids were exposed to the limit concentration, the solvent control and the control. The test item Fluowet AC 812 solidwas analytically verified by GC-MS at the start of the exposure intervals (0 and 24 h) and at the end of the exposure intervals (24 and 48 h) in samples of the limit concentration of 1.30 mg/L and the control. The solvent control was analytically verified at test start (0 h) and test end (48 h).
The measured concentrations of the
test item at the start of the exposure were 1.10 mg/L (at 0 hours) and
1.12 mg/L (at 24 hours). The measured concentrations at the end of the
exposure intervals were 0.760 mg/L corresponding to a recovery rate of
58 % (after 24 hours) and 0.405 mg/L corresponding to a recovery rate of
31 % (after 48 hours) of the nominal value. The geometric mean measured
concentration of the test item was calculated to be 0.785 mg/L.
All effect values are based on the geometric mean measured concentration
of 0.785 mg/L of the test item Fluowet AC 812 solid.
Water quality parameters (i.e. pH-values and dissolved oxygen concentrations), measured at the start (0 and 24 h) and at the end of each exposure interval (24 and 48 h), were within the acceptable limits. The validity criteria of the test guideline were fulfilled.

At the limit concentration of 1.30 mg/L of the test itemFluowet AC 812 solid, which corresponds to the geometric mean measured concentration of 0.785 mg/L, no effects were observed on Daphnia magna.
A static limit test (DAI84111) was conducted with the water accomodated fraction. The test vessel was coated with the test item for 14 days before the test started. Duration of the test was 96 hours. Thirty test organisms were exposed to the water accomodated fraction and the control. For the preparation of the water accomodated fraction, a suspension with a nominal loading of 100 mg/L was shaken for 96 hours. After phase separation, the clear liquid phase was used for the test.
All effect levels are based on the initially measured concentration of the test item (0.14 mg/L). At the end of the test the concentration of the test item was below the detection limit of 0.009 mg/L. Sorption to the glass of the test vessels is unlikely as the walls were already pre-coated for 14 days before the test started.
The 96-hour NOEC and LC0 was 0.14 mg/L. The 96-hour LC50 and LC100 was > 0.14 mg/L.
Supporting studies:
A limit test (DAi84113) with the water accomodated fraction was conducted on test item. A coating period of 14 days was carried out prior to study start. The study was conducted under static conditions for a period of 48 hours. Twenty test organisms were exposed to the water accomodated fraction and control. The water accomodated fraction was analytically verified by GC analysis. The mean
measured concentration of the water accomodated fraction was 0.70 mg/L.
At the water accomodated fraction concentration of 0.70 mg/L, no biologically significant effect was determined. No immobilization was observed in either the control or the saturated solution at 24 or 48-hours. The 48-hour NOEC and EC0 values were 0.70 mg/L. The 48-hour EC50 value was > 0.70 mg/L.
Water quality parameters of pH and dissolved oxygen concentration measured at 0 and 48 hours were determined to be within acceptable limits. The validity criteria of the test guideline were fulfilled.
