Key result
Surface tension:
> 27 - < 31 mN/m
Temp.:
23 °C
Conc.:
1 g/L
Remarks on result:
other: The CMC is determined to be in the range between 1300 – 2200 mg/L at pH 7. Also, the surface tension at 1 g/L has been determined to be in the range between 27 – 31 mN/m.The temperature range is 23-25°C
Conclusions:
The CMC is determined to be in the range between 1300 – 2200 mg/L at pH 7. Also, the surface tension at 1 g/L has been determined to be in the range between 27 – 31 mN/m. The temperature range is 23-25°C

Description of key information
