Material Safety Data
● General description
MEG is rather stable under normal use condition as it does not polymerize or decompose
by itself. It is not classified as flammable but capable to burn.
It has a relatively low degree of acute and chronic oral toxicity and only slightly irritates eyes and skin.
The estimated fatal dose is 100ml for man.
