Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The surface tension of dodecylamine hydrochlroides was determined experimentally according to OECD 115 guideline. Since primary
amines exhibit a pKa of about 10.6 they appear protonated under environmental conditions.
In order to determine their surface tension, the corresponding hydrochloride thereof was used.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

Assuming a surface tension of 72.75 mN/m for pure water, dodecylamine can be regarded as being surface active, as its surface tension is below 60 mN/m.
