Description of key information
The surface tension of a solution of test item (90% of the saturation concentration) was determined according to OECD 115 guideline, using the ring method. Substances showing a surface tension lower than 60 mN/m under the conditions of this method, should be regarded as being surface active. The surface tension was determined to be 51.9 mN/m. Thus, the substance is considered to be a surface-active.
Key value for chemical safety assessment
- Surface tension:
- 51.9
- in mN/m at 20°C and concentration in mg/L:
- 128.3
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
