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 smoke and haze machines.IUPAC name:4-Oxa-2,6-heptandiol and4-Oxa-1,7-heptandiolOther names:1,1'-Oxybis(1-propanol) and1,1'-Oxybis(2-propanol)Identifiers:CAS number 25265-71-8 YesEC number 246-770-3 Properties:Molecular formula C6H14O3Molar mass 134.173 g/molAppearance colorless liquidDensity 1.0206 g/cm3 at 20 ?CBoiling point 230.5 degrees CSolubility in water miscible with water, soluble in ethanol.
