Nevertheless, there are hydrolysis data available for EMA indicating
that according to OECD test guideline 111 the half-life is ~ 2400 days
at pH7 and ~ 4800 days at pH 3 (Miller,
EMA, like other lower methacrylate esters, is stable at neutral and
acidic pH. Under normal environmental conditions, abiotic degradation by
hydrolysis is not expected to play an important role in the degradation
of EMA in the environment.
