Description of key information
The surface tension of streams in this category is 71.2-72 mN/m, indicating that these streams are not surface active.
Key value for chemical safety assessment
- Surface tension:
- 71.6
- in mN/m at 20°C and concentration in mg/L:
- 198
Additional information
Data from GKA competence centre analytics (2008, 2008 & 2009) are available for three of the streams in this category (64742 -49 -0: 71.2 mN/m, 92128-65-9: 71.7 mN/m, 68476-55-1: 72.0 mN/m, all values measured at 90 % solution saturation and at 20°C). These data will be read across to all category members.
The mean of the surface tension values for the category is 71.6 mN/m at 20°C 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.
