Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Surface tension
Surface tension:
71 mN/m
Temp.:
20 °C
Conc.:
1 g/L

Any other information on results incl. tables

Overall mean calibration corrected surface tension = 72.0 mN/m

Harkins-Jordan corrected value = 71.0 mN/m

Applicant's summary and conclusion

Conclusions:
The surface tension of a 1 g/L aqueous solution of the test substance was found to be 71.0 mN/m. As the result was greater than 60 mN/m, the test substance was not considered to be surface active.
