Audited Supplier 1, 2-propanediol is an organic compound (diol) with the formula C3H8O2. It is usually a slightly sweet, odorless, colorless, transparent, thick liquid. Chemically, it is a type of diols that can be miscible with various solvents such as water. It can be manufactured by hydration of oxide and is primarily used to produce polymers, but is also used as a food additive, with the E code E1520. It has another isomer.
1,2-propanediol is a synthetic liquid substance that absorbs water. It is also used to make polyester compounds, and as a base for deicing solutions. It is used by the chemical, food, as an antifreeze when leakage might lead to contact with food. It is used to absorb extra water and maintain moisture ,cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. It is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions. Other names for glycol are 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. It is clear, colorless, slightly syrupy liquid at room temperature. It may exist in air in the vapor form, although it must be heated or briskly shaken to produce a vapor. It is practically odorless and tasteless.
