Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Surface tension test was carried out according to the OECD Guideline 105 (1981). The surface tension of the substance was determined using the ring tensiometer method. Depending on the concentration, the substance reduces significantly the surface tension of water. The average values are 46.3 mN/m, 61.7 mN/m and 71.2 mN/m at 1005 mg/l, 100.5 mg/l and 10.05 mg/ concentrations and at 21.3-20.0 °C, 20.6-20.3 °C and 20.5-20.1 °C, respectively.
