Description of key information

stable at pH 4 and pH 7, hydrolyses slowly at pH 9

Key value for chemical safety assessment

Additional information

Abiotic degradation by hydrolysis of 2-ethylhexyl methacrylate was measured in an OECD guideline study. 2-EHMA was stable at pH 4 and pH7. At pH9 the measured half-life (t 1/2 ) for 2-EHMA at 25 °C is 58 days. Since 2-EHMA is readily biodegradable, hydrolysis appears not to be an important aqueous degradation process for this chemical.
