Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Tension of the test substance is 71.0 mN/m (1 g/L solution) at 21.1 ± 0.5 °C, using a ring method based on ISO 304, designed to be compatible with Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item was considered not to be surface-active.
Key value for chemical safety assessment
- Surface tension:
- 71
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Temperature is 21.1 °C, at which the surface tension was determined, not 20 °C. But the determined value can be taken in the same way for the chemical safety assessment because the difference is very slight.
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.
