- Key result
- Surface tension:
- ca. 56.6 mN/m
- Temp.:
- 20.4 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of a nominally 1.0 g/L solution of test item in water has been determined to be 56.6 ± 3.5 mN/m at 20.4 ± 0.5 °C.
The test item was considered to be surface-active. - Executive summary:
Surface Tension. 53.6 ± 3.5 mN/m (mean of duplicate, nominally 1.0 g/L solutions) at 20.0 ±
0.5 °C, using a ring method, designed to be compatible with Method A.5 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 to be
surface-active.

Additional information
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.
