Dipropylene glycol is a colorless, odorless, slightly viscous liquid. it has a low vapor pressure, and is miscible with water.??
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.?? ??
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.?? ??
Thick odorless, colorless liquid. Sinks and mixes with water.??? ?? ??
Dipropylene glycol is hygroscopic. Water soluble.?? ???
Dipropylene glycol can react vigorously with acids and oxidizing materials. Dipropylene glycol is incompatible with strong bases. Dipropylene glycol is incompatible with peroxides.????
Minor eye irritation????
Dipropylene glycol is combustible.?? ??
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.Carcinogenicity
Dipropylene glycol has not been tested specifically for carcinogenicity; however, based on the results of a cancer bioassay of propylene glycol (to which dipropylene glycol is rapidly converted), dipropylene glycol is not expected to have carcinogenic potential.???????? ?? ?? ? ???
