Description of key information

The surface tension of the structural analogue is 28 mN/m at -9 °C

Key value for chemical safety assessment

Additional information

The test substance is considered not to be surface active at 20 °C.

According to REACH Regulation (Annex VII, 7.6, column II), the study on surface tension needs only to be done if based on the structure surface-active properties are to be expected or predicted or surface-activity is a desired property of the material. The test substance does not contain any functional groups indicating surface-active properties.
