Multifunctional Humectant Solvent (Pentylene Glycol)

Pentylene Glycol is a versatile, water-soluble glycol used in cosmetic formulations as a humectant, solvent, and preservative-boosting co-factor. It helps attract and retain moisture to improve skin hydration and softness, while also enhancing spreadability and contributing to a smooth, non-sticky sensorial profile. As a solubilizer, it supports the incorporation and performance of various actives, botanical extracts, and fragrance components, and it can improve overall microbial robustness by supporting preservative systems—often enabling lower preservative load or improved efficacy depending on the formula. Pentylene Glycol is commonly found across a wide range of leave-on and rinse-off products, including serums, moisturizers, toners, cleansers, deodorants, and hair care, typically used at low to moderate levels and formulated for broad compatibility and good tolerance across skin types.
