The relevant pharmacokinetics are as follows: Ethylene glycol and methanol are both readily absorbed from the gut (e.g. with peak serum levels occurring ~1 hour after ingestion). Ethylene glycol has a half-life of ~3-8 hours, whereas methanol has a half-life of ~2-3 hours. As parent alcohol levels fall, acidic metabolites rise.
