- Remarks:
- 2017-03-23
- Type of method:
- flask method
- Water solubility:
- < 1 g/L
- Conc. based on:
- test mat.
- Incubation duration:
- 10 min
- Temp.:
- 24.5 °C
- Remarks on result:
- other: pH not measured because no solubilisation occurs during the preliminary test
- Conclusions:
- The solubility in water of the test item was determined to be lower than 1 g/L at 24.5 °C ± 0.5 °C.
- Executive summary:
The water solubility of tribenzyl phosphite acid has been determined according to EC A.6 method and OECD test guideline 105 in compliance with GLP. A visual interpretation demonstrated that the water solubility of test substance at 25°C was < 1 g/L.
The temperature during the assays 1 to 7 was recorded between 24.4 °C and 25.0 °C with a mean temperature at 24.8 °C.
