Химические свойства
Dipropylene glycol is a colorless, odorless, slightly viscous liquid. it has a low vapor pressure, and is miscible with water.
Использование
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.
Методы производства
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.

Химическая реактивность
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.
Канцерогенность
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.
