Pentylene Glycol
What is Pentylene Glycol?
Pentylene glycol, or 1,2-pentanediol, is a synthetic aliphatic diol alcohol produced from petrochemical or renewable sources like sugarcane-derived pentose sugars. Commonly found in water-based cosmetics such as serums, toners, creams, and hair products, it serves multiple roles. As a solvent, it dissolves lipophilic and hydrophilic ingredients, enhancing product homogeneity, controlling viscosity, and optimizing evaporation rates for even application. It functions as a humectant by attracting atmospheric water to the skin's surface, supporting hydration. Additionally, it conditions skin and hair by improving texture and flexibility while exhibiting antimicrobial properties that boost preservative systems, allowing lower concentrations of traditional preservatives. Its colorless, odorless nature makes it ideal for clean, gentle formulations across various product types.
