- Butylene Glycol: Definition and Uses. Butylene Glycol is a chemical compound also known as 1,3-Butanediol. Like glycerin, Butylene Glycol (BG) is a humectant, a chemical that helps your skin (or other substances) retain moisture. It is also a solubilizer, which means it makes other substances (such as fat) more soluble in water. Like glycerin, it is a common ingredient in cosmetics. It is also a common ingredient in food.

The Truth About Propylene Glycol, According to a Chemist However, some manufacturers have recently made the decision to no longer include propylene glycol in their products. Do not be alarmed by the term antifreeze or by the chemical, propylene glycol. It is safe at the low concentrations when used in personal care products. This is possibly due to misinformation and propaganda circulated on the Internet in the interest of marketing natural products.

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.ike ethylene glycol, propylene glycol is able to lower the freezing point of water, and so it is used as aircraft de-icing fluid. Water-propylene glycol mixtures dyed pink to indicate the mixture is relatively nontoxic are sold under the name of RV or marine antifreeze.
