Description of key information
Surface tension was determined to be 66.5 ± 2.0 mN/m for the 0.11 g/L loading rate and 56.2 ± 1.0 mN/m for the 1.1 g/L loading rate at 22.0 ± 0.5°C. The test item was considered to be surface active but this was dependent on loading rate (OECD 115 and EU Method A.5).
Key value for chemical safety assessment
Additional information
GUIDELINE
Surface tension was investigated using a ring method designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the oECD Guidelines for Testing of Chemicals, 27 July 1995.
METHOD
The surface tension of nominally 90 % saturated solutions was determined using two loading rates (0.11 and 1.1 g/L) at 22.0 ± 0.5°C.
RESULTS
Surface tension was determined to be 66.5 ± 2.0 mN/m for the 0.11 g/L loading rate and 56.2 ± 1.0 mN/m for the 1.1 g/L loading rate at 22.0 ± 0.5°C.
CONCLUSION
The test item was considered to be surface active but this was dependent on loading rate.
