Applicant's summary and conclusion
- Conclusions:
- The surface tension of a nominally 1 g/L of test item in water solution has been determined to be 72.1 mN/m at 21.4 ± 0.5 °C. The test item was considered not to be surface-active.
- Executive summary:
Surface Tension was determined to be 72.1 mN/m for a nominally 1 g/L solution at 21.4 ±0.5 °C, using a ring method, 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.
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.
