1,3-Propanediol 1,3-Propanediol is a multifunctional cosmetic ingredient commonly used as a natural-origin humectant, solvent, and formulation enhancer in modern skincare, haircare, and personal care products. Valued for its lightweight skin feel and excellent compatibility, it helps improve hydration while enhancing the performance and sensory profile of formulations. Derived from renewable sources such as corn sugar fermentation, 1,3-Propanediol is frequently chosen as an alternative to petroleum-based glycols in clean beauty and naturally inspired formulations. It helps attract and retain moisture on the skin while also improving the delivery and dispersion of many cosmetic actives and botanical extracts. Its silky, non-tacky skin feel makes it ideal for serums, creams, toners, mists, shampoos, conditioners, scalp products, and water-based formulations where a smooth elegant finish is desired. It can also help support preservative systems and improve overall formulation aesthetics.
