Description of key information

In conclusion, the surface tension of FAT 60'253/A in water (90 % of saturation concentration) was determined to be 72.1 mN/m at 20.0 °C ± 0.2 °C.

Key value for chemical safety assessment

Surface tension:
72.1
in mN/m at 20°C and concentration in mg/L:
90

Additional information

The determination of the surface tension of an aqueous solution of FAT 60'253/A was based on the OECD Guideline No. 115: "Surface Tension of Aqueous Solutions" (1995) and on the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.5 "Surface tension", EEC Publication No. L383, December 1992.

In conclusion, the surface tension of FAT 60'253/A in water (90 % of saturation concentration) was determined to be 72.1 mN/m at 20.0 °C ± 0.2 °C. Based on the criteria as outlined in the OECD Guideline, FAT 60'253/A is not a surface active substance.
