Dipropylene glycol Usage And Synthesis

Chemical Properties

colourless liquid

Chemical Properties

Dipropylene glycol is a colorless, odorless, slightly viscous liquid.

Uses

dipropylene 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 Methods

Dipropylene 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 Description

Thick odorless, colorless liquid. Sinks and mixes with water.

Air & Water Reactions

Dipropylene glycol is hygroscopic. Water soluble.

Reactivity Profile

Dipropylene glycol can react vigorously with acids and oxidizing materials. Dipropylene glycol is incompatible with strong bases. Dipropylene glycol is incompatible with peroxides.

Health Hazard

Minor eye irritation

Fire Hazard

Dipropylene glycol is combustible.

Chemical Reactivity

Reactivity 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.
