- Specific details on test material used for the study:
- - Purity: 100%
- Surface tension:
- 36.25 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- Surface tension of the test item was 36.25 nN/m.
- Executive summary:
The surface tension of the test item was determined using the OECD harmonized ring method in accordance with OECD Guideline 115. The surface tension of a test solution at a concentration of 1 g/L in water and at 20°C was 36.25 mN/m. According to this, the test item is considered to be surface active.
