PPG-16 is Propylene glycol, also known as 1,2-propanediol, is a synthetic (i.e., man-made) organic alcohol that attracts/absorbs water. Due to this property, propylene glycol is broadly used by food, drug, and cosmetic and personal care product manufacturers. The U.S. Food and Drug Administration (FDA) has classified propylene glycol as a food additive that is “generally recognized as safe” (GRAS).
Propylene glycol and polypropylene glycols attract water and function as a humectant ;found in moisturizers to enhance the appearance of skin by reducing flaking and restoring suppleness. Propylene glycol is one of the most widely used ingredients in cosmetics and personal care products, where it also serves as a viscosity decreasing agent, solvent and fragrance ingredient. It is used in many types of cosmetic formulations including facial cleansers, moisturizers, bath soaps, shampoos and conditioners, deodorants, shaving preparations, fragrances, etc.
