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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Surface tension
Administrative data
Link to relevant study record(s)
Description of key information
Surface tension (0.1% V/V, 20 °C) 49.7 < surface tension < 61.6 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 55
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Surface tension was investigated by the EU method A.5 (in line with OECD 115). At 1 g/L and 20°C the surface tension was >49.7 <61.6 mN/m and >51.3 < 65.2 mNm. The surface tension of an aqueous preparation of the test item (ß= 1 g/L) at 20°C was found to decrease from a value above 60 mN/m to about 50 mN/m within a measuring period of 3 and 5 hours, 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.
