Description of key information

 1.74 mg/L at 20°C at pH 7.5  (of Monoester)
<0.2 mg/L at 20°C at pH 7.0 (of Diester)
7.7 mg/L at 20°C at pH 5-6.4 (overall resp. substance as-is)

Key value for chemical safety assessment

Additional information

The test substance is a mixture of 3 main components which are Monoester, Diester and PEG 300.

The water solubility was determined by column elution method on Monoester and Diester which are two representative selection components of test substance.

The overall water solubility of test substance as-is was determined to be 7.7 mg/L at 20°C at pH range 5 -6.4 by flask method. Since the test substance contains PEG 300 which is water soluble and would affected the solubility of Di- and Monoester.
