Propylene glycol has good solubility, and it has low toxicity and irritation. It is widely used as a solvent, extraction solvent and preservative for injectable drugs (such as intramuscular injections, intravenous injections) and non-injectable drug preparations (such as oral liquids, eye preparations, ear preparations, dental preparations, rectal-vaginal preparations, transdermal preparations, etc.). It is a better solvent than glycerol and can dissolve many substances such as corticosteroids (hormones), chloramphenicol, sulfonamides, barbiturates, reserpine, quinidine, hydrocortisone dehydroxy acid, aescin sulfate, nitrogen mustard hydrochloride, vitamins A and D, many volatile oils, most alkaloids and many local anesthetics.
