Propylene Glycol is a versatile and widely used cosmetic ingredient functioning as a humectant, solvent, emollient, and penetration enhancer. It attracts moisture from the environment into the skin, helping to keep formulations hydrating and smooth, while also improving the delivery of active ingredients.
Due to its excellent solvency, it helps dissolve otherwise hard-to-dissolve ingredients like fragrance oils, preservatives, and plant extracts. Propylene Glycol also plays a stabilizing role in emulsions and enhances the performance of other humectants and preservatives in a wide range of cosmetic applications.
