- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 2008

- Type of method:
- ring method
- Key result
- Surface tension:
- 70 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 mg/L
- Conclusions:
- The surface tension of an aqueous solution of the test item with a concentration of 1 mg/mL was determined to be 70 mN/m at 20 °C.
- Executive summary:
The surface tension of the test item was determined in an experimental study according to Regulation (EC) No 440/2008 Method A.5. and OECD Test Guideline 115 using the ring method. The surface tension was determined with a test item concentration of 1 g/L at 20 °C. The mean surface tension was 70 mN/m. The mean result is well above the trigger value of 60 mN/m. The test item is therefore classified as not surface active.
Reference
The test item solution was held at constant temperature (20.0 ± 0.5 °C) in a temperature controlled room. The surface tension of Methyl vinyl glycolate (MVG) aqueous solution (ca. 1 mg/mL) was found to be 70.1 (140 sec*), 69.9 (138 sec*), 70.1 (140 sec*), 69.2 (**), 70.2 (138 sec*) and 70.0 (139 sec*) mN/m (resulting in a mean value of 70 mN/m) at 20 °C using the ring method. Thus, the surface tension of water (72.6 mN/m) was only minimal affected by the test item.
The mean result is well above the trigger value of 60 mN/m. The test item is therefore classified as not surface active.
