- Sampling method: For the determination of the actual test item concentrations in this semi-static test, duplicate samples were taken from each treatment just before the start of the first and of the last renewal periods (Days 0 and 3). At the end of these renewal periods (Days 1 and 4), additional samples were taken for determination of the stability of the test item during the renewal periods of 24 hours. From the two highest nominal test concentrations of 2.46 and 4.9 mg/L, samples were only taken at the beginning of the exposure period and after 24 hours, respectively, since all fish were dead at these concentrations at the corresponding observation dates.
- Sample storage conditions before analysis: All samples were taken from the approximate center of each aquarium without mixing the test medium, and were stored deep-frozen (at about -20 °C) immediately after sampling. - Vehicle:
- no
- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: Prior to the start of the test and prior to each test medium renewal, a stock solution of nominal 25 mg/L (corresponding to 15 mg sulfosuccinate/L) was freshly prepared by completely dissolving 62.5 mg of the test item (dosed in the range of 62.5 to 63.2 mg) in 2500 mL of test water using ultrasonic treatment for 15 minutes and stirring for 15 minutes at room temperature. Then, adequate volumes of the intensively stirred stock solution were diluted with test water to obtain the desired test concentrations. The test media were freshly prepared just before introduction of the fish (= start of the exposure) and before each test medium renewal.
- Controls: dilution water only
- Evidence of undissolved material (e.g. precipitate, surface film, etc): No remarkable observations were made concerning the appearance of the test media. All test media were clear solutions throughout the entire test duration. - Test organisms (species):
- Danio rerio (previous name: Brachydanio rerio)
- Details on test organisms:

- Weight at study initiation (mean and range, SD): the mean body wet weight was 0.16 ± 0.010 g (Mean ± SD).
- Method of breeding: similar to test conditions
- Feeding during test: no
ACCLIMATION

- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 96 h
- Hardness:
- 15 mg/L as CaCO3
- Test temperature:
- 21-22 °C
- pH:
- 7.2 to 7.5
- Dissolved oxygen:
- The oxygen concentration was at least 8.2 mg/L, corresponding to at least 91% oxygen saturation.
- Nominal and measured concentrations:
- The following nominal concentrations of Butanedioic acid, sulfo-, 1,4-diisodecyl ester, sodium salt were tested: 0.31, 0.62, 1.23, 2.46 and 4.9 mg/L (corresponding to 0.19, 0.38, 0.75, 1.5 and 3.0 mg sulfosuccinate/L). Additionally, a control (test water without test item) was tested in parallel.
In the analyzed test medium samples from the start and end of the first and last test medium renewal periods the measured test item concentrations ranged between 80 and 114% of the nominal value. Consequently, the test water renewal ensured nearly constant concentration of the test item during the test and the reported biological results are related to the nominal test item concentration. - Details on test conditions:

- Executive summary:
In the Klimisch 1 GLP study from Kimmel (2013) the acute toxicity of Butanedioic acid, sulfo-, 1,4-diisodecyl ester, sodium salt to zebra fish (Danio rerio) was determined in a 96‑hour semi-static test with daily test medium renewal according to the EU Commission Directive 92/69/, Part C.1, the Commission Regulation (EC) No 440/2008, Part C.1 and the OECD Guideline for Testing of Chemicals No. 203 (1992). The following nominal concentrations of Butanedioic acid, sulfo-, 1,4-diisodecyl ester, sodium salt were tested:0.31, 0.62, 1.23, 2.46 and 4.9 mg/L(corresponding to 0.19, 0.38, 0.75, 1.5 and 3.0 mg sulfosuccinate/L). Additionally, a control (test water without test item) was tested in parallel. In the analyzed test medium samples from the start and end of the first and last test medium renewal periods the measured test item concentrations ranged between 80 and 114% of the nominal value. Consequently, the test water renewal ensured nearly constant concentration of the test item during the test and the reported biological results are related to the nominal test item concentration.
In the control and at the test concentrations up to and including 0.62 mg/L (corresponding to 0.38 mg sulfosuccinate/L), all fish survived until the end of the test and no visible abnormalities were observed in the test fish. At the next higher test concentration of 1.23 mg/L (0.75 mg sulfosuccinate/L), two test fish died at the end of the test. At the next higher test concentration of 2.46 mg/L (1.5 mg sulfosuccinate/L), all fish were dead after 24 hours of test duration. At the highest test concentration of 4.9 mg/L (3.0 mg sulfosuccinate/L), all fish were dead already after 2.5 hours of test duration. Thus, the 96‑hour NOEC and LC0of Butanedioic acid, sulfo-, 1,4-diisodecyl ester, sodium salt to zebra fish were both determined to be 0.62 mg/L (corresponding to 0.38 mg sulfosuccinate/L). The 96‑hour LOEC was1.23 mg/L (corresponding to 0.75 mg sulfosuccinate/L). The 96‑hour LC50of Butanedioic acid, sulfo-, 1,4-diisodecyl ester, sodium salt was calculated to be 1.4 mg/L (corresponding to 0.88 mg sulfosuccinate/L) with a 95% confidence interval of 1.0-2.3 mg/L (0.63-1.4 mg sulfosuccinate/L). The 96‑hour LC100was 2.46 mg/L (corresponding to 1.5 mg sulfosuccinate/L).
