2,3-プロパンジオール 用途と合成の方法
  • 化学的特性clear viscous liquid
  • 使用Used as a solvent.
  • 使用Next to water, propylene glycol is the most common moisture- carrying vehicle used in cosmetic formulations. It has better skin permeation than glycerin, and it also gives a pleasant feel with less greasiness than glycerin. Propylene glycol is used as a humectant because it absorbs water from the air. It also serves as a solvent for anti-oxidants and preservatives. In addition, it has preservative properties against bacteria and fungi when used in concentrations of 16 percent or higher. There is a concern that propylene glycol is an irritant at high concentrations, though it appears to be quite safe at usage levels under 5 percent.
  • brand nameSentry Propylene Glycol (Union Carbide); Sirlene (Dow Chemical).
  • 一般的な説明Thick odorless colorless liquid. Mixes with water.
  • 空気と水の反応Water soluble.
  • 反応プロフィール1,2-Propanediol is hygroscopic. 1,2-Propanediol is sensitive to excessive heat (tends to oxidize at high temperatures). 1,2-Propanediol can react with oxidizing materials. 1,2-Propanediol is incompatible with acid chlorides, acid anhydrides, chloroformates, and reducing agents. 1,2-Propanediol dissolves many essential oils. A mixture of 1,2-Propanediol with hydrofluoric acid and silver nitrate was put in a glass bottle which burst 30 minutes later.
  • 健康ハザードLiquid may irritate eyes.
  • 火災危険1,2-Propanediol is combustible.
  • 接触アレルゲンPropylene glycol is used as a solvent, a vehicle for topical medicaments such as corticosteroids or aciclovir, an emulsifier and humectant in food and cosmetics, and as antifreeze in breweries, in the manufactures of resins. It was present as an occupational sensitizer in the color film developer Flexicolor?. Patch tests in aqua are sometimes irritant.
  • 純化方法Dry the diol with Na2SO4, decant and distil it under reduced pressure. [Beilstein 1 IV 2468.]
  • 定義PGはプロピレングリコールの表示名称である。本品は、次の化学式で表される二価アルコールである。
  • 化粧品の成分用途保湿.湿潤剤、保水剤、減粘剤、皮膚コンディショニング剤、溶剤、香料
