Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- - Concentrations:
- Sampling method: The concentrations of the test substance were analysed in the duplicate test media samples from both sampling times (0 and 48 hours). From the control samples only one of the duplicate samples was analysed from each of both sampling times.

Test solutions
- Vehicle:
- yes
- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
200.8 mg of test item were added directly to 2008 ml of test water and carefully stirred for about 24 hours at room temperature in the dark to dissolve as much of the test item as possible. After cessation of stirring and a following period of settling to allow phase separation, the aqueous phase, i.e. the water accomodated fraction, was drawn off carefully and used as the test medium.
Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- TEST ORGANISM
- Common name: Water flea
- Strain: Clone 5
- Source: In house laboratory culture (i.e. IBACON testing laboratory)
- Age at study initiation (mean and range, SD): 6.25 to 21.5 h old
- Method of breeding: The cultivation of the parental Daphnia was performed in reconstituted water of a similar quality with regards to pH, the constituent salts and total hardness as the test water used in the test. The test organisms were not first brood progeny
- Food type: Green algae (Desmodesmus subspicatus) freshly grown in the lab
-Frequency: Daily
ACCLIMATION
- Was not necessary, since the test was performed in the same medium as the culturing

TEST MEDIUM / WATER PARAMETERS
- Source/preparation of dilution water: Elendt "M4" reconstituted water
- Alkalinity: 0.9 mmol/L
- Culture medium different from test medium: No
OTHER TEST CONDITIONS
- Adjustment of pH: Yes
- Photoperiod: 16 h light: 8 h dark
- Light intensity: 940 - 1150 lux
EFFECT PARAMETERS MEASURED (with observation intervals if applicable) : Immobility of the Daphnia was determined by visual observation after 24 and 48 h. Those animals not able to swim within 15 seconds after gentle agitation of the test beaker were considered to be immobile (even if they could still move their antennae).
TEST CONCENTRATIONS
- Range finding study
- Test concentrations: 1, 10, 100 mg/L
- Results used to determine the conditions for the definitive study: Yes
Since a dose-related effect of the test material was observed in an additional range-finding test for the water accommodated fractions of nominal 10 and 1.0 mg/L. Nominal test concentrations 10, 4.6, 2.1, 0.95 and 0.43 mg/L were tested in the main experiment. - Reference substance (positive control):

Any other information on results incl. tables
The concentration of test substance recorded by total organic carbon analysis was below the limit of quantification in the control and test vessels. The LOQ was equivalent to 3 mg/L. Test concentrations were therefore based on nominal values.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the test conditions, the 48 h EC50 of the test substance was > 100 mg/L (nominal). The 48 h NOEC was 100 mg/L (nominal).
- Executive summary:
A study was conducted to determine the acute toxicity of 'Soybean oil, deodorizer distillates' to Daphnia magna in a static 48 h immobilisation test (OECD Guideline 202 and EU method C.2).
Daphnia magna (20 per dose) were exposed to water accommodated fraction of the nominal test concentrations of 0 and 100 mg/L for 48 h. Immobility of theDaphnia was determined by visual observation after 24 and 48 h. Analytical verification of the test concentrations were conducted at the concentrations of the test material in the test medium. The samples collected at start and after 48 h were analysed via the TOC-method.
Under the test conditions, the 48 h EC50 of the test substance was > 100 mg/L (nominal). The 48 h NOEC was 100 mg/L (nominal).
