Description of key information

The surface tension of the aqueous solution of  ethyldimethylamine was determined to be 67.0 mN/m at 20°C +/-0.4°C. 
According to the criteria as mentioned in the directive: substances showing a surface tension lower than 60 mN/m under the conditions of the method should be regarded as being surface active material ,Ethyldimethylamine should not be regarded as being surface active material.

Key value for chemical safety assessment

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