Read up on PG. It is in almost every liquid cough med. out there including the childrens cough med.
PG has been used as the aqueous-based chemical additive in asthma inhalers and nebulizers since the 1950s, with no serious side effects known. PG, because of its water-retaining properties, is the compound of choice for delivering atomized medication. It is also a common diluent for injectable medications.
The FDA includes Propylene glycol on its list of substances Generally Recognized as Safe (GRAS), and it meets the requirements of acceptable compounds within Title 21 of the Code of Federal Regulations. Considering PG has been widely used for many years without serious side effects, the substance can reasonably said to be of negligible concern.
