Product Details: Propylene glycol
Propylene glycol is a synthetic liquid organic compound with the molecular formula C3H8O2 or CH3CHOHCH2OH. Its CAS is 57-55-6. The clear, colorless, slightly syrupy liquid that readily absorbs water is also used to make polyester compounds, and as a base for deicing solutions.
The chemical, food, and pharmaceutical industries use propylene glycol as antifreeze when leakage might lead to contact with food. It is also used to create artificial smoke or fog for fire-fighting training and in theatrical productions.
Propylene glycol is also recognized as 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. The only industrial process used for manufacturing propylene glycol is by direct hydrolysis of propylene oxide with water.
Applications
Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions. Propylene glycol is used by the chemical, food, and pharmaceutical industries as an antifreeze when leakage might lead to contact with food. The Food and Drug Administration (FDA) has classified propylene glycol as an additive that is “generally recognized as safe” for use in food. It is used to absorb extra water and maintain moisture in certain medicines, cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions. Other names for propylene glycol are 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature. It may exist in air in the vapor form, although propylene glycol must be heated or briskly shaken to produce a vapor. Propylene glycol is practically odorless and tasteless.
