Dipropylene glycol Usage And Synthesis
  • Chemical Propertiescolourless liquid
  • Chemical PropertiesDipropylene glycol is a colorless, odorless, slightly viscous liquid.
  • Usesdipropylene glycol may be incorporated into a cosmetic for a variety of purposes including to mask odors or to perfume a product. In addition, it can help decrease product viscosity and serves as a solvent for essential oils and fragrance oils.
  • Production MethodsDipropylene glycol is prepared commercially as a by-product of propylene glycol production. Three linear isomers are possible, but these have not been separated and studied, and the exact composition of the commercial product is not known. It is also possible to prepare cyclic isomers such as 2,6-dimethyl-1,4-dioxane and 2,5-dimethyl-1,4-dioxane, but these are not likely to form under conditions employed commercially.
  • General DescriptionThick odorless, colorless liquid. Sinks and mixes with water.
  • Air & Water ReactionsDipropylene glycol is hygroscopic. Water soluble.
  • Reactivity ProfileDipropylene glycol can react vigorously with acids and oxidizing materials. Dipropylene glycol is incompatible with strong bases. Dipropylene glycol is incompatible with peroxides.
  • Health HazardMinor eye irritation
  • Fire HazardDipropylene glycol is combustible.
  • Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
