Description of key information
The surface tension of a solution of laurylimidazole at 20 mg/L in water at 20 °C is 45.0 mN/m. Laurylimidazole is considered to be surface active.
Key value for chemical safety assessment
Additional information
The surface tension was determined according to OECD 115 harmonized ring method and EU Method A.5. This study was conducted in accordance with GLP standards and is classified as reliable without restrictions. In a supporting study, the surface tension of a ca. 50 mg/L solution of laurylimidazole is between 30.86 and 58.32 mN/m. The supporting study was performed using the Wilhelmy Plate method and an automated tensiometer. The supporting study was not GLP compliant and no temperature was recorded. Therefore, the key study is the preferred value.
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.
