Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

After application of the calibration factor, the mean result was 49.65 mN/m. This result is lower than 60 mN/m, and therefore correction using the Harkins-Jordan factor was performed.

The mean corrected result was 47.88 mN/m and is therefore considered to be surface active.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension of MK92K was determined according to OECD Guideline 115 (Surface Tension of Aqueous Solutions) and EU Method A.5 (Surface Tension).
