Dipropylene glycol finds many uses as a plasticizer, an intermediate in industrial chemical reactions, as a  polymerization initiator or monomer, and as a solvent. Its low toxicity and solvent properties make it an ideal additive for perfumes and skin and hair care products. It is also a common ingredient in commercial fog fluid, used in entertainment industry fog machines.
