Monopropylene Glycol (USP/EP)

Description

Monopropylene Glycol (MPG), also known as Propylene Glycol (USP/EP), is a synthetic, colorless, and odorless liquid with hygroscopic properties, meaning it can attract and retain moisture. Classified as safe for use in food, pharmaceuticals, and cosmetics, MPG meets United States Pharmacopeia (USP) and European Pharmacopoeia (EP) standards. In e-liquids, MPG acts as a base ingredient that helps carry flavorings and nicotine. It produces a throat hit that simulates the sensation of smoking, making it popular among vapers. Additionally, it is less viscous than Vegetable Glycerin (VG), promoting better wicking in atomizers and a stronger flavor delivery.
