Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The corrected surface tension of a test solution at 90% of C4 Acrylate saturation solubility in water at 20.0°C is 42.6 mN/m. C4 Acrylate is considered a surface active material.

Key value for chemical safety assessment

Additional information

The surface tension test of an aqueous solution of the test substance was determined according to OECD TG 115 harmonized ring method and EEC Directive 92/69 EEC, A.5. A saturated solution was diluted to 90% of saturation and transferred to the measurement vessel. Nine measurements were made at 19-27 minutes to show equilibration. The arithmetic mean of the equilibrated values was calibrated against a water standard and corrected using Harkins-Jordan values. This study was conducted in accordance with OECD TG 115 and is compliant with GLP standards. Therefore this study is classified as reliable without restrictions.
