Description of key information
A study was performed to determine the water solubility of the test substance according to EU method A.6 and OECD guideline 105 in compliance with GLP. Water solubility is above 95 g/L at 20°C for the two main constituents. The substance can be described as very soluble in water.
Key value for chemical safety assessment
- Water solubility:
- 95 g/L
- at the temperature of:
- 20 °C
Additional information
A study was performed to determine the water solubility of the test substance according to EU method A. 6 and OECD 105 in compliance with GLP.
The assessment of water solubility by the flask method was performed at 20 degrees C and the measurement of the test substance was carried out using HPLC.
The two main constituents showed a solubility of 139 g/L (Component W) and 95 g/L (Component U); whereas the two isomers showed a water solubility of 40 g/L (Component X) and 26 g/L (Component V).
Each of the two main constituents and the two isomers of Reactive Red F00-0149 are very soluble in water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
