20 propylene glycol properties

Propylene Glycol : Dermatitis

Propylene glycol (PG) is a common ingredient in many cosmetics topical skin preparations medications and foods Propylene glycol's potential as a contact allergen has long been recognized and the first study of patch tests to PG was performed in the 1950s 1 However the significance of PG as a contact allergen has been ambiguous Patch tests to PG are often weak and can be difficult to
