- Source: All fish used in the test originate from a single brood stock at DR.NOACK-LABORATORIEN from a single brood stock. (supplier: Niedersächsischer Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz, An der Scharlake 39, D-31135 Hildesheim)
- Length at study initiation (length definition, mean, range and SD): Average body length: 2.84 cm
- Weight at study initiation (mean and range, SD): Average body weight: 0.3 g
- Method of breeding: Holding was performed at the test facility at 23+/-2 °C and diffuse light (0.1 - 10 µmol photons • m-2 • s-1, natural photoperiod). The water was changed at least once per week. The dissolved oxygen concentration was more than 80 % of the air saturation value. No disease treatments were administered throughout holding and testing. Food was provided 3 times per week. The amount of food was 4 % of the fish body weight per feeding day. The test fish were not fed 24 h before the test started.
- Feeding during test: No feeding during test
ACCLIMATION
- Acclimation period: Zebrafish with at least 12 days of acclimatisation and mortality < 5 % within these days before the study starts were used in the test.
- Acclimation conditions (same as test or not): Same as test
- Type and amount of food: 4 % of the fish body weight per feeding day. The test fish were not fed 24 h before the test started. Food: Sera Vipan; SERA GMBH, D-52518 Heinsberg
- Feeding frequency: 3 times per week.
- Health during acclimation (any mortality observed): No mortality observed, no disease treatments were administered throughout holding and testing.

TEST MEDIUM / WATER PARAMETERS
- Source/preparation of dilution water: Same as for holding
- Culture medium different from test medium: Tap water of local origin was used for holding. The water was filtered on activated charcoal and aerated for at least 24 h to remove chlorine.
Nominal water parameters:
Total hardness: 10 - 250 mg CaCO3/L
pH-value: 6.0 - 8.5
- Intervals of water quality measurement: pH-value, temperature and oxygen saturation were measured in all vessels at the beginning of the test and every 24 h (from old and new media). Total hardness of the water was determined at the beginning out of the test control. During the test the water temperature was recorded continuously with a data logger (once per hour).
OTHER TEST CONDITIONS
- Adjustment of pH: No
- Photoperiod: natural
- Light intensity: 0.1 - 10 µmol photons x m-2 x s-1
EFFECT PARAMETERS MEASURED (with observation intervals if applicable) : Fish were considered dead if there was no visible movement (e.g. gill covers movement) and if touching of the caudal peduncle produced no reaction. Records were kept of visible abnormalities (e.g. loss of equilibrium, swimming behaviour, respiratory function, pigmentation, etc.). Observations were made after 24, 48, 72 and 96 h.

- The concentrations leading to 0 and 100 % mortality (LC0 and LC100) after 96 h were determined directly from the test results. LC10,20,50-values have not to be calculated in a limit test.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- In this studySorbitancaprylat has shown no mortality after 96 hours when tested with Zebrafish with the limit concentration of 100 mg/L.
The LC50 after 96 hours is > 100 mg test item/L. All effect levels are given based on the nominal concentration level of the test item.
