Sample 2

 Time (mins)  Reading (mN/m)  Temperature (°C)
 141  52.0  20.0
 154  52.0  20.0
 168  52.0  20.0
 181  52.0  20.0
 194  52.0  20.0

Mean Sample 1 result       :       52.0 mN/m              Mean Sample 2 result      :       52.0 mN/m

pH of Sample 1               :       6.6                           pH of Sample 2              :       6.4

Mean result                   :       52.0 mN/m

Overall temperature       :       20.0 ± 0.5 ºC

Conclusions:
The mean surface tension of duplicate solutions of test item prepared at 90 % saturated concentration in water has been determined to be 52.0 mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active.
Executive summary:

The general physico-chemical properties of FRET 10-0367 have been determined.  

Surface Tension. 52.0 mN/m (mean result from duplicate aqueous solutions prepared at 90% saturation concentration) at 20.0 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008, and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.  The test item was considered to be surface-active.

Description of key information

The mean surface tension of duplicate solutions of test item prepared at 90 % saturated concentration in water has been determined to be 52.0 mN/m at 20.0 ± 0.5 °C, using a ring method according to EU method A.5 and OECD TG 115.  The test item was considered to be surface-active.

Key value for chemical safety assessment
