Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Not surface active at 1 g/L.
Key value for chemical safety assessment
- Surface tension:
- 71.5
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
A fully reliable, GLP, experimental study was conducted with hexamethylenediamine at the maximum concentration of 1 g/L in demineralized water at 20°C. The result was 71.5 mN/m, which is very close to the value of water, and much above the threshold of 60 mN/m, therefore the substance is not considered as a surface active agent.
A supporting litterature data gives an informative value of 0.0346 N/m for anhydrous liquid HMD at 60°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
