The volume of M4 medium were weighed into one 2L beaker, stirred with magnetic stirrer (300 rpm) and the corresponding amount of the test substance was added to the stirring medium. Preparation was stirred for 24 h.
The test substance preparation was then filtered through a filter paper circle Ø 320 mm (Whatman Schleicher & Schuell GmbH, Dassel, Germany). The control was treated the same way. - Vehicle:

- Details on test solutions:
- Based on a NON-GLP pre-test the test substance C-SAT 100051 was identified as poorly soluble in M4 medium and the test was performed as a limit test with a test substance preparation of 100 mg/L M4 medium.

- Method of breeding: The daphnids were held in beakers with a nominal capacity of 2000 ml. Each beaker was filled with approximately 1400 ml M4 medium. Between 15 and 20 adult organisms were held in one beaker in order to get a high reproduction rate and viable offspring.
- Feeding during test : yes
- Food type: The algae Desmodesmus subspicatus served as food during holding
- Amount: ad libitum
- Frequency: During holding daphnia were fed from Monday to Friday with an appropriate amount of algae which could be roughly consumed per day. On weekends and public holidays no feeding took place.

The test substance C-SAT 100051was tested in the Acute Daphnia Toxicity Test according to the OECD Guideline for the Testing of Chemicals No. 202 (April 2004) usingDaphnia magna(Straus) as test organism.
The experiment was carried out as a limit test (100 mg/L) and as a static test, i.e. the test substance preparation was not exchanged for the whole exposure period of 48 hours.

Additional information
The results of this study showed that the test substance C-SAT 100051 induced no immobilisation to the exposed Daphnia at 100 mg/L within 48 hours. The EC50 value after 48 hours of exposure was >100 mg/L. The NOEC was ≥100 mg/L.
The test was conducted in accordance with the study plan and met all relevant validity criteria. There were no interferences in this test.
Dehylub 1757 displayed a 48h LC50 value of 644.61 mg/L to Acartia tonsa (screening test) in the water phase. The 48h result was calculated by extrapolation, since a 100% effect was not observed at any concentration.
