Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Surface tension data are available for streams within this Category. The surface tension range for this Category was 70.2 - 72 mN/m in 90% saturation concentration.

The mean of the surface tension values for the category is 71.13 mN/m and this has been used to complete the 'key value for chemical safety assessment'. These values were given for a concentration of 90% saturation concentration and the 90% value has been applied to the mean water solubility in order to provide a concentration in mg/L.

Key value for chemical safety assessment

Surface tension:
71.1
in mN/m at 20°C and concentration in mg/L:
