- Specific details on test material used for the study:
- Batch/Lot No.: 021015
Purity: 50.0 % (w/w)
Expiry date: 24 November 2021 - Key result
- Water solubility:
- > 1 000 g/L
- Conc. based on:
- test mat. (dissolved fraction)
- Loading of aqueous phase:
- 95 other: % (w/w)
- Incubation duration:
- 24 h
- Temp.:
- 30 °C
- pH:
- >= 7.63 - <= 8.12
- Details on results:
- The standard EC A.6 / OECD 105 methodology was not applicable to this test item due to its miscibility with water. Therefore, a range of sample concentrations ranging from 5 to 95% w/w were prepared for visually assessment.
As the test item was noted to be fully dissolved in water at levels ranging from 5.32 to (at least) 50.0 % w/w of solution, it was considered that the water solubility of the test item was greater than 1000 g/kg of water. - Conclusions:
- The water solubility of the test item has been determined to be greater than 1000 g/kg of water at 20.0 ± 0.5 °C.
