Propanediol

Propanediol is a naturally derived diol obtained via fermentation of corn sugar, valued in skincare for its exceptional humectant, emollient, and solvent properties. This clear, low-viscosity liquid attracts and retains moisture in the stratum corneum, improving skin hydration and barrier function while imparting a smooth, non-sticky feel. It also enhances penetration of active ingredients and boosts preservative efficacy, increasing overall formula stability and performance. Compatible with a wide range of formulations—creams, serums, cleansers, and sunscreens—propanediol is non-irritating, non-sensitizing, and an eco-friendly alternative to petroleum-based glycols, making it ideal for all skin types, including sensitive and acne-prone complexions.
