Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
ca. 72.58 mN/m
Temp.:
21 °C
Conc.:
0.998 g/cm³
Remarks on result:
other: The surface tension of 1 g/l aqueous solution of MCA was 72.3 mN/m at 21°C

Any other information on results incl. tables

Test temperature: 21 +-0.5°C

Density of water at 21°C: 0.998 g/cm 3

Surface tension of water at 21°C: 72.58 mN/m

The corrected surface tension measurements are:

distilled water ==> 72.9 mN/m

test solution 1==> 72.3 mN/m

test solution 2 ==> 72.2 mN/m

The results from test 1 and 2 were sufficiently close for the mean (72.3 mN7m) to be used

The time between testing and the preparation of the test solution was 120 minutes (test 1) and 150 minutes (test 2)

Applicant's summary and conclusion

Conclusions:
The surface tension of 1 g/l aqueous solution of MCA was 72.3 mN/m at 21°C
