- Key result
- Surface tension:
- 65 mN/m
- Temp.:
- 20 °C
- Conc.:
- 554.22 mg/L
- Conclusions:
- The surface tension at 20 °C is 64.96 mN/m. The test item is not to be regarded as surface active.
- Executive summary:
The surface tension at 20 °C of test item was determined by the ring method according to OECD Test Guideline 115 and EC No. 440/2008 Part A. Method A.5.
The surface tension at 20 °C is 64.96 mN/m. The test item is not to be regarded as 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.
