An aqeous preparation of the test item (90% saturation concentration) was tested at 20°C. The surface tension of the purified water used to make the solution was also tested for reference. The surface tension of the purified water was 72mN/m at 20°C. The test item is not surface active

Conclusions:
The surface tension of 68476-55-1 is 72mN/m. The test item is not surface active.
Executive summary:

This study was conducted to a standard guideline and according to GLP and so is considered fully reliable for use as a key study. The surface tension of 68476-55-1 is 72mN/m. The test item is not surface active.

An aqeous preparation of the test item (90% saturation concentration) was tested at 20°C. The surface tension of the purified water used to make the solution was also tested for reference. The surface tension of the purified water was 71.7mN/m at 20°C. The test item is not surface active

Conclusions:
The surface tension of 92128-65-9 is 71.7mN/m. The test item is not surface active.
Executive summary:

This study was conducted to a standard guideline and according to GLP and so is considered fully reliable for use as a key study. The surface tension of 92128-65-9 is 71.7mN/m. The test item is not surface active.

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.
