CAS RN: 97953-16-7
Appearance/Physical state: Yellow to brown paste
Batch: RL55/17
Purity: 100%
Expiry / Retest date: 31 January 2019
Storage conditions: Room temperature, in the dark - Key result
- Surface tension:
- ca. 52.2 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of nominally 1 g/L solutions of the substance in water has been determined to be 52.2 mN/m at 20. ± 0.5 °C, using a ring method. The substance was considered to be surface-active.
- Executive summary:
The surface tension of nominally 1 g/L solutions of the substance in water has been determined to be 52.2 mN/m at 20. ± 0.5 °C, using a ring method. The substance was considered to be surface-active.
