Key result
Surface tension:
52.4 mN/m
Temp.:
20 °C
Conc.:
90 vol%
Conclusions:
The surface tension of an aqueous solution of Florhydral at a 90% saturated concentration is 52.4 mN/m.
Based on the criteria as outlined in the EEC guideline, it is concluded that Florhydral should be regarded as a surface active material.
Executive summary:

The determination of the surface tension of an aqueous solution of Florhydral was based on EEC-directive 92/69 EEC, A.5 surface tension (1992).

The surface tension of an aqueous solution of Florhydral at a 90% saturated concentration is 52.4 mN/m.

Temperature of measurement was 20.0 +/- 0.5 °C.

Based on the criteria as outlined in the EEC guideline, it is concluded that Florhydral should be regarded as a surface active material.
