methyl ethylene glycol
Propylene glycol is used as:
– disinfectant disinfectant.
A stabilizer (any agent added to another substance in order to preserve its natural and chemical properties from change).
A water miscible cosolrent co-solvent.
Propylene glycol is widely used as a solvent and preservative in many pharmaceuticals and is a better solvent than glycerine and is able to dissolve a large number of substances such as: corticosteroids, phenols, sulfa compounds, barbiturates, vitamins (DA), most alkaloids and a lot of topical drugs. .
