Description of key information

The water solubility of 1,1-DPE was determined in an GLP-compliant and Klimisch 1 study according to OECD 105. The measured water solubility was 5.51 ±0.06 mg/L at 20.0 ± 0.5 °C. 
In a second study with Klimisch score 3 the test was terminated although the diffrence in concentration of the test substance was greater than 15% between day 2 and 3. Therefore no equilibrium could be reached and the results of the study are considered as unreliable.

Key value for chemical safety assessment

Water solubility:
5.51 mg/L
at the temperature of:
20 °C

Additional information

The reported study is GLP compliant and has Klimisch score 1.

The measured water solubility was 5.51 ±0.06 mg/L at 20.0 ± 0.5 °C. No further testing is required.
