The test item has a mean surface tension of 52.1 mN/m at 20 °C.
Thus, the test item is to be regarded as surface active.
Description of key information
Surface tension = 52.1 mN/m at 90% of solubility and at 20 °C (OECD 115, A.5.)
Key value for chemical safety assessment
- Surface tension:
- 52.1
Additional information
The surface tension of test item was determined by ring method.
Based on the testing result, the test item is to be regarded as surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
