Pre-treatment of test item and preparation of test item concentrations:
A direct weighing was prepared to produce the only test concentration of 100 mg/L based on the active ingredient (35.25 %). To achieve this 1418.3 mg of the test item were added to 5 litre of dilution water, treated for 60 seconds at 8000 rpm with an ultra turrax and afterwards stirred for 24 h on a magnetic stirrer.
The pH was measured to be pH 8.2.
Finally 7 fish were given to the only test item concentration and the control.
- Test vessels : glass aquaria holding 5 L of test media covered by glass plates
- Experimental design : 1 test concentration plus 1 control, 7 fish per test concentration, no feeding during the exposure period, static system
- Method of initiation : fish were placed in prepared media
- Loading : 0.71 g body weight (wet weight) per litre
- Photoperiod : 16 h light: 8 h dark
- Temperature : 21.6 to 22.5 °C
- Aeration : gentle aeration via narrow glass tubes
- Test item concentration : 100 mg/L (active ingredient)
- Method of administration : direct weighing
- Medium renewal : none
- Duration of exposure: 96 hours
- Criteria of effects : The criterion of death used in this study was the absence of response to physical stimulation. In addition to observations on mortality at 2, 24, 48, 72 and 96 hours, type and incidence of sub lethal effects compared with control fish were observed. - Reference substance (positive control):

- Sublethal observations / clinical signs:
No toxic effects against fish were observed at a limit test concentration of 100 mg/L.
The results are expressed in terms of nominal concentrations. Effective concentrations correspond to 97.4 % of nominal values at 0 hours and to 98.4 % of nominal values at 96 hours.
- Validity criteria fulfilled:
- yes
- Remarks:
- (-The mortality in the controls did not exceed 10 % by the end of the test. -The dissolved oxygen concentration remained above 60 % of the air-saturation value throughout the exposure period. -The pH did not vary by more than 1 unit.)
- Conclusions:
- The acute toxicity to fish (danio rerio) was tested in a static test. After 96 hours of exposure no effect against fish were observed at a limit test concentration of 100 mg/L.
- Executive summary:
A study was performed to assess the acute toxicity of the test item to Danio rerio under static conditions. The study was conducted in accordance with Council Regulation (EC) No 440/2008, Method C.1 'Acute toxicity for Fish' (2008) which is in most parts equivalent to the OECD Guideline for Testing of Chemicals No. 203 'Fish, Acute Toxicity Test' (1992).
An acute daphnia toxicity rang finding test and an algal growth inhibition rang finding test preceded the fish test. They provided information about the concentration which was used in the fish test.
Because of the anticipated low toxicity of the test item, fish were exposed in the main test to a limit test concentration of nominally 100 mg/L of active ingredient of the substance for a period of 96 hours. As no toxic effects against fish were observed, no statistical analysis was required to determine the LC 50. Additionally any abnormal behaviour or appearance of the fish was reported every 24 hours.
After 96 hours of exposure a LC50 of >100 mg/L (nominal) was determined.
This toxicity study is classified accptable and satisfies the guideline requirements for the acute fish.

Additional information
In accordance with REACH Regulation, Art. 3, and ECHA "Guidance for identification and naming of substances under REACH and CLP" v1.2, March 2012, substances have to be separated from solvents if this is not affecting the stability of the substance or changing its composition.
In this case, separation of water would only be possible by thermical damaging of the substance. Furthermore, it was not possible to spray dry the pigment solution as it stuck to and partly melted on the conus dryer.
