- Temp.:
- 20.3 °C
- Conc.:
- 90 other: % of saturated concentration
- Conclusions:
- The average surface tension of two independent measurements was 63.9 mN/m for a 90 % aqueous solution at 20.3 ± 0.1 °C. The substance is considered not surface active.
- Executive summary:
The surface tension of the test substance was determined using the ring method in accordance with OECD TG 115 following GLP principles. The average surface tension of two independent measurements was 63.9 mN/m for a 90% aqueous solution at 20.3 ± 0.1 °C. The substance is considered not surface active.
Reference
