Propylene glycol Propylene glycol is a clear, colorless and hygroscopic liquid. Propylene glycol contains an asymmetrical carbon atom, so it exists in two enantiomers. The commercial product is a racemic mixture.Pure optical isomers can be obtained by hydration of optically pure propylene oxide.t is produced on a large scale and is primarily used in the production of polymers but also sees use in food processing as the E-number E1520. The compound is sometimes called α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).

Propane: Liquefied Petroleum Gas (LPG) Propane: Liquefied Petroleum Gas (LPG). Propane, or liquefied petroleum gas (LPG), is a clean-burning fossil fuel that can be used to power internal combustion engines. LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions and the greenhouse gas carbon dioxide (CO 2). LPG is usually less expensive than gasoline, it can be used without degrading vehicle performance, and most LPG used in U.S. comes from domestic sources.

Propylene Glycol and Cats Proplyene Glycol is an additive that is present in many dog foods to help with moisture content. In dog food it is an acceptable ingredient that the FDA considers as generally safe. If propylene glycol was present in high levels in dog food it could be toxic, however. Propylene Glycol is used in food to accomplish several things: 1  To absorb extra water and help keep food moist.  As a solvent for colors and flavors in the food.

Ethylene glycol Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound primarily used as a raw material in the manufacture of polyester fibers and fabric industry, and polyethylene terephthalate resins (PET) used in bottling.thylene glycol is used as a protecting group for carbonyl groups in organic synthesis. Treating a ketone or aldehyde with ethylene glycol in the presence of an acid catalyst (e.g., p-toluenesulfonic acid; BF3•Et2O) gives the corresponding a 1,3-dioxolane, which is resistant to bases and other nucleophiles.
