- Details on test solutions:
- The water-accommodated fraction (WAF) was prepared for the test. This was done by
mixing the nominal load of 10 g/L resp. 11.2 mL/L test item (based on a density of
0.898 g/mL given by the sponsor) with the corresponding amount of dilution water and stirring
vigorously for 7 days. The lower unfiltered phase of this water-accommodated fraction
was used.
The lower treatments were prepared by dilution of this WAF with dilution water.
Test organisms
- Test organisms (species):
- Daphnia magna

- Specification
Species Daphnia magna
Variety STRAUS
Strain Berlin
Sex female
Age between 0 and 24 hours

In-house breeding since 27. September 2007
Selection of the test system was made following the proposal of the guidelines.
Animal Husbandry
Daphnia magna is bred in the LAUS GmbH throughout the year. The animals are kept for
the use in toxicity tests. They multiply by parthenogenesis, thus being genetically identical.
The husbandry is performed similar to the method described in the OECD guideline, following
SOP 115 002 01 („Zucht und Hälterung von Daphnia magna Straus“), Version 12
from 02. Feb. 2015.
Vessels preserving glasses, nominal volume 2 L
Medium M4-Medium (recipe of ELENDT)
Food unicellular green algae (Desmodesmus subspicatus)
Medium renewal twice a week
Photo period 16/8 hours, using neon tubes
Temperature 20 2 °C
Study design

Test conditions
- Hardness:

- Test temperature:
- 20.9 – 22.6 °C
- pH:

- Dissolved oxygen:
- 8.7 - 9.0 mg/L
- Nominal and measured concentrations:
- 0.1 / 0.32 / 1.0 / 3.2 / 10 g/L nominal concentration
Because only in the highest concentrated treatment test item was detected whilst no immobility
was observed, the determination of the results was based on the mean of the
measured DOC concentrations in the treatment 10 g/L and the carbon content of the test
item of 74.48 %.
The geometric mean of measured concentration was 1.7 mg/L - Details on test conditions:

- VALIDITY
Immobilisation in the controls may not exceed 10 %.
Immobilisation in the controls was 0 %.
The concentration of dissolved oxygen at the end of the test must be at least 3 mg/L.
The lowest concentration of dissolved oxygen at the end of the test was 8.7 mg/L.
The pH-value in the test solutions should not vary by more than 1.5 units during the
test.
The highest variation was 0.3 units. - Results with reference substance (positive control):
- Potassium dichromate K2Cr2O7 (CAS No. 7778-50-9) was used as positive control in a
current reference study. The 24h-EC50 value was determined as 1.6 mg/L.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- No effect of Salacos 13 on Daphnia magna was detected up to limit of solubility.
The following results were determined for the test item Salacos 13
48h-NOEC ≥ 1.7 mg/L (limit of solubility)
48h-LOEC > 1.7 mg/L (limit of solubility)
24h-EC50 > 1.7 mg/L (limit of solubility)
48h-EC50 > 1.7 mg/L (limit of solubility) - Executive summary:
One valid experiment was performed.
The study was performed using 5 concentrations ranging from 0.1 to 10 g/L nominal concentration.
For each test concentration, 20 Daphnia were exposed to the test item for 48
hours in a static test system. After 24 and 48 hours, the immobilised Daphnia were counted.
The concentrations showed no significant toxicity. None of the animals were immobilised
in the blank control.
Potassium dichromate K2Cr2O7 (CAS No. 7778-50-9) was used as positive control in a
current reference study to assure that the test conditions are reliable.
At the start and at the end of the test, the content of the test item in the test solutions was
determined using measurement of dissolved organic carbon (DOC). Due to the low solubility
of the test item, the measured DOC concentration in the treatments was very low. Only
in the highest concentrated treatment, the measured DOC concentration demonstrates the
presence of dissolved test item in the test solution. The measured concentration in the
treatment of nominal 10 g/L can be stated as limit of solubility in test medium.
Because only in the highest concentrated treatment test item was detected whilst no immobility
was observed, the determination of the results was based on the mean of the
measured concentrations in this treatment (nominal 10 g/L).
The following results were determined for the test item Salacos 13 (species: Daphnia
magna).
48h-NOEC ≥ 1.7 mg/L (limit of solubility)
48h-LOEC > 1.7 mg/L (limit of solubility)
24h-EC50 > 1.7 mg/L (limit of solubility)
48h-EC50 > 1.7 mg/L (limit of solubility)
