Pentylene glycol (1,2-pentanediol) is a multifunctional cosmetic ingredient used as a humectant, solvent, and antimicrobial/preservative booster. It is increasingly used as a 'natural' alternative to traditional glycols and can be derived from sugarcane.
Used to hydrate skin, enhance product stability, and boost the efficacy of traditional preservatives, often allowing reduction of their concentration. It has mild antimicrobial properties.
Pentylene glycol has a good safety and tolerability profile. It is less irritating than propylene glycol and is suitable for sensitive skin formulations. No carcinogenic or endocrine effects are identified. It is COSMOS/ECOCERT acceptable when bio-based. Minor irritation is possible at high concentrations in compromised skin.
