Description of key information
In a GLP-compliant study in accordance with EC A.5 and OECD 115 using the OECD harmonized ring method, the surface tension of a 1 g/L aqueous test substance solution at 20°C has been determined as 73.4 mN/m. The substance is not surface active according to the criterium in the EC A.5 guideline.
Key value for chemical safety assessment
- Surface tension:
- 73.4
- in mN/m at 20°C and concentration in mg/L:
- 1 000
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.
