Description of key information

The study does not need to be conducted because based in structure surface tension is not expected.

Key value for chemical safety assessment

Additional information

A study acc. EU method A.5 has been performed. The surface tension was reported with 65.9 m/Nm at 20° C at a concentration of 1010 mg/l. This value is similar to the surface tension of water and confirms that methacrylic acid is not a surface active substance.
