Description of key information
The water solubility of the test substance was found to be 440 mg/L and 697 mg/L, and the substance is therefore considered to be moderately soluble.
Key value for chemical safety assessment
- Water solubility:
- 697 mg/L
- at the temperature of:
- 20 °C
Additional information
Two studies were conducted to assess the water solubility of the test substance. Both studies were considered reliable as they were conducted on the registered substance according to OECD Testing Guideline 105. The key study gave a water solubility with a value of 697 mg/L recorded at 20°C, and a solubility of 440 mg/L (temperature not related) in the supporting study. The test substance is considered to be moderately water soluble.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
