Results and discussion

Surface tension
Surface tension:
>= 72.1 - <= 72.2 mN/m
Temp.:
20 °C
Conc.:
1 004 mg/L

Any other information on results incl. tables

The surface tension of Yellow LF 6881 aqueous solution (502.0 mg / 500 ml) was found to be 72.1, 72.1, 72.2, 72.2, 72.1 mN/m (resulting a mean value 72.1 mN/m) atusing the ring method.

As this value is higher than 60 mN/m, Yellow LF 6881 is not classified as surface active.

Applicant's summary and conclusion

Conclusions:
The surface tension of Yellow LF 6881 aqueous solution (1004 mg / L) was found to be 72.1 mN/m by using the ring method.
Executive summary:

The surface tension of Yellow LF 6881 aqueous solution (502.0 mg / 500 ml) was found to be 72.1, 72.1, 72.2, 72.2, 72.1 mN/m (resulting a mean value 72.1 mN/m) atusing the ring method.

As this value is higher than 60 mN/m, Yellow LF 6881 is not classified as surface active.
