Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

5% mass solution in water (at 20C): 56.4mN/m
In accordance with column 2 of REACH Annex VII, the surface tension study (required in section 7.6) does not need to be conducted as surface activity is neither expected or predicted from structure, nor is it a desired property of the material.

Key value for chemical safety assessment

Additional information

Based on data from the two constituents it is concluded that the reaction mass does not have any surface active properties.


Published experimental data on ethanol indicates that the surface tension of a solution of ethanol in water at a concentration of 1g/l will be similar to that of pure water.Ethanol does not therefore have surface active properties.
