Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Surface-active at 20 °C.
Key value for chemical safety assessment

- 61.7
- in mN/m at 20°C and concentration in mg/L:
- 100.5
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
