Propylene glycol CAS 57-55-6

Propylene glycol is a colourless, odourless, slightly sweet viscous liquid with good hygroscopicity and solubility.It is widely used in food, medicine, cosmetics and other fields as humectant, solvent or stabiliser; it is used in industry for synthetic resin, antifreeze and so on.Its safety is high, but it should be noted that high concentration contact may cause slight irritation.
