Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
