What It Does

Pentylene Glycol is a five-carbon diol that serves as a multifunctional ingredient, offering both moisturizing properties and natural preservative-boosting capabilities. Formulators favor it because it enhances the efficacy of traditional preservative systems while providing a lighter, less sticky skin feel compared to propylene glycol or butylene glycol. Its unique antimicrobial activity against bacteria and fungi allows for reduced preservative concentrations in formulations, making it particularly valuable in natural and sensitive-skin products.
