Description of key information

Surface tension (Ring method): 54.0 mN/m (5% neat solution),  47.7 mN/m (15% neat solution)

Key value for chemical safety assessment

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

Additional information

Surface tension values of 47.7 mN/m and 54.0 mN/m at 20°C were measured with the ring method for the 15% and 5% products, respectively (Mekelburger, 2007). This indicates that peracetic acid does not need to be regarded as surface active, because only substances exhibiting a surface tension < 60 mN/m when tested at a concentration of 0.1% are regarded as surface active.
