Applicant's summary and conclusion
- Conclusions:
- The surface tension of an aqueous solution of the analogue substance was determined at 20 °C to be 47.1 mN/m at a concentration of 3 g/L water and to be 39.4 mN/m at a concentration of 15 g/L water. Based on the determination of the surface tension of the analogue substance, surface activity has to be concluded. Since both substances belong to the same type of substance group due to their chemical structure, surface activity is also to be concluded for the substance subject of registration.
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.
