Description of key information

With a CMC of 26 mg/L at pH 7, Amides, C18-unsatd., N-[3-(dimethylamine)propyl] is considered as slightly soluble.

Key value for chemical safety assessment

Water solubility:
26 mg/L
at the temperature of:
23 °C

Additional information

Taking into account intrinsic properties of the tested substance (surface active), critical micelle concentration (CMC) was used as a surrogate for water solubility. CMC for Amides, C18-unsatd., N-[3-(dimethylamine)propyl] is determined to 26 mg/L at pH 7.0 . The operating temperature is room temperature, in this case 23°C. Also, the surface tension at 0.5 g/L solution has been determined to 29 mN/m.
