Description of key information

The CMC is determined to 64 mg/L at pH 7. Also, the surface tension at 1 g/L and pH 7 has been determined to 37 mN/m.  

Key value for chemical safety assessment

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

Additional information

Given that the watersolubility of the acetate salt is higher than the watersolubility of the amine the read across is considered as “the worst case scenario”.
