2-Ethoxyethyl acetate is rapidly metabolized to
2-ethoxyethanol in the blood via
hydrolysis. Then, 2-ethoxyethanol is metabolized, mainly by
alcohol dehydrogenase, to 2-ethoxyacetaldehyde, which is further metabolized by aldehyde dehydrogenase to 2-ethoxyacetic acid (2-EAA) in the liver. These two compounds are the likely active metabolites, which are thought to be involved in some of the toxic effects. Also in the liver,
ethylene glycol is produced. All this reactions belong to the phase I of the biotransformation process. In rats, EAA can be conjugated with glycine or may suffer O-deethylated. After this, it can be metabolized to carbon dioxide. An extra pathway in these animals involves microsomal P450 mixed function oxidases, with deethylation producing acetaldehyde and ethylene glycol. == Safety ==
