What It Does

Propanediol (1,3-propanediol) is a bio-based glycol produced through the fermentation of corn-derived sugars, offering a sustainable alternative to petroleum-derived glycols like propylene glycol. It provides excellent humectancy with a lighter, less sticky skin feel than traditional glycols, while also enhancing the solubility of actives and boosting preservative efficacy. Formulators favor it for its clean label appeal, superior sensory profile, and ability to improve product texture without the heavy or tacky feel associated with other diols.
