Propylene Glycol is diol alcohol (contains two hydroxy groups in 1 and 2 positions - Propane-1,2-diol), a humectant or humidifying and delivery ingredient used in cosmetics. It is a water-white liquid readily soluble in water.
When used in small amounts to keep products from melting in high heat or freezing when it is cold. Propylene Glycol also helps active ingredients penetrate the skin.
Propylene glycol is often used as an aid to solubilize other raw materials such as parabens. It is used in cosmetic formulations such as creams and lotions at typical use levels of 1-5%.
