Description of key information

Surface tension: Not surface-active

Key value for chemical safety assessment

Additional information

On the basis of structure, neither the substance nor its hydrolysis products are expected to be surface active. Therefore, the requirement for testing is waived in accordance with Column 2 of REACH Annex VII. A surface tension of 63.7 mN/m at 20.7°C was obtained in a test conducted according to OECD 115 and in compliance with GLP, but the result was disregarded because the amount of test substance used for the study was overloaded above the recommended saturation concentration (about 1120 mg/l). The substance has a measured preliminary water solubility of approximately 3 mg/l and a predicted water solubility of approximately 6 mg/l.

Furthermore, the rapid hydrolysis rate means that the measured value does not relate to parent substance.
