What is Propylene Glycol?

Propylene glycol (also known as 1,2-propanediol or propane-1,2-diol) is an organic compound. It is a colorless, nearly odorless liquid that is miscible with acetone, water and chloroform. Propylene glycol molecule itself is chemically inert (not chemically reactive), and because of this special feature propylene glycol becomes an idealistic compound when seeking to combine contrasting chemical elements to form a single, homogenous fluid. It act as an emulsifier that connects and stabilizes active ingredients that is insoluble with one another (would not mix) and create a stable homogenous fluids that will allow the intended final project. This inert feature of propylene glycol also allows it to develop an ability to attract water/moisture. Hence, propylene glycol is one of the most widely used ingredients in cosmetic product as it can help to hold and dissolves active ingredients equally in a medium (e.g. perfume, shower foam, lipstick) and act as a moisturizer in cosmetic formulas (e.g. facial cream, toner)
