Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
36.19 mN/m at 22 °C (pure liquid)
Key value for chemical safety assessment
- Surface tension:
- 36.19
Additional information
The surface tension of the substance was evaluated according to the ring method following the OECD Guideline 115 and ISO 304:1985. The substance was transfered as is in a glass cup. Sample analysis were performed in triplicate on three different sample aliquots. With the aid of suspended platinum ring of 6 cm of circumference (0.3 mm thickness) posed in contact with sample free surface, the digital tensiometer measured the force required to raise the ring from liquid surface and to draw up the liquid film formed from this contact.
Surface tension of pure liquid at 22 °C is 36.19 mN/m.
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.
