Propanediol 1,3 – Natural, Eco-Friendly Humectant for Skin & Haircare Formulations

Propanediol 1,3 (also written as 1,3-Propanediol or Propanediol 1,3) is a plant-derived humectant obtained through the fermentation of renewable corn sugar. It serves as a natural alternative to propylene glycol and glycerin, offering superior skin-feel, moisture retention, and formulation stability.

Highly favored by cosmetic formulators and clean beauty brands, this ingredient provides exceptional hydration with a non-tacky, lightweight texture, making it suitable for a broad range of skincare, haircare, and personal care applications.
