Propanediol (1,3)

Propanediol 1,3 is a versatile, plant-derived multifunctional cosmetic ingredient produced through the fermentation of corn sugar. A cleaner, more skin-friendly alternative to traditional propylene glycol, it serves simultaneously as a humectant, solvent, emollient, and preservative booster — making it one of the most useful and efficient actives in any DIY cosmetic toolkit. Lightweight, non-greasy, and exceptionally well-tolerated by the skin, it enhances the performance and feel of virtually every formulation it’s added to.
