Key result
Surface tension:
61.3 mN/m
21 °C
1 vol%
The surface tension of a 1% v/v aqueous solution of the test substance was determined to be 61.3 mN/m at 21°C.

Description of key information

The surface tension of a 1% v/v aqueous solution of the test substance has been determined to be 61.3 mN/m at 21°C in a GLP-compliant study following the OECD harmonized ring method performed by Huntingdon Research Centre Ltd. (1990) and considered to be reliable without restrictions (Klimisch 1).

Key value for chemical safety assessment
