Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The surface tension of the substance is 59.8 mN/m at 22.2 deg. C

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 210

Additional information

The surface tension of the substance was determined by a ring method following EU Method A.5 and OECD 115 guidelines. A White Electrical Institute interfacial tension balance was used which gave a direct reading for surface tension that was within the required accuracy of +/- 0.5mN/m as a result of the reduced ring dimensions.

A test solution was prepared by loading at a nominal concentration of 1.21 g/L. Measurements on a dilution of the supernatant after centrifuging gave an average surface tension measurement of 59.8 mN/m at 22.20C.
