El '''glicol''' o '''etilenglicol''' (nomenclatura [[IUPAC]]: età-1,2-diol), [[fórmula química]]: C<sub>2</sub>H<sub>6</sub>O<sub>2</sub>, és un [[compost orgànic]] molt usat en la [[indústria]] de l'[[automòbil]] com [[anticongelant]] i com a precursor de [[polímer]]s. En la seva forma pura, és un [[líquid]] inodor, incolor, xaropós i de [[gust dolç]]. L'etilenglicol és [[tòxic]] i la ingestió pot ser [[mort]]al.
