化学的特性
Dipropylene glycol is a colorless, odorless, slightly viscous liquid. it has a low vapor pressure, and is miscible with water.
使用
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.
調製方法
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.
一般的な説明
Thick odorless, colorless liquid. Sinks and mixes with water.
空気と水の反応
Dipropylene glycol is hygroscopic. Water soluble.
反応プロフィール
Dipropylene glycol can react vigorously with acids and oxidizing materials. Dipropylene glycol is incompatible with strong bases. Dipropylene glycol is incompatible with peroxides.
健康ハザード
Minor eye irritation
火災危険
Dipropylene glycol is combustible.
化学反応性
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.
発がん性
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.
