Dipropylene glycol is a mixture of three isomeric chemical compounds, 4-oxa-2,6-heptandiol, 2-(2-hydroxy-propoxy)-propan-1-ol, and 2-(2-hydroxy-1-methyl-ethoxy)-propan-1-ol. It is a colorless, nearly odorless liquid with a high boiling point and low toxicity.

Uses

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.{{cite web |title=Dipropylene Glycol LO+ (DPG LO+) |url=http://www.dow.com/propyleneglycol/prod/dpglo.htm |publisher=Dow Chemical |access-date=2009-04-07 |url-status=dead|archive-url=https://web.archive.org/web/20090619082902/http://www.dow.com/propyleneglycol/prod/dpglo.htm |archive-date=2009-06-19 }}
