Pentylene glycol is a synthetic humectant that helps skin attract and retain moisture. It also functions as a solvent, helping to dissolve other ingredients in a formula, and can enhance the preservative system of a product. This multi-functional ingredient contributes to product stability and skin hydration.

Pentylene glycol serves multiple roles in skincare, primarily as a humectant to draw moisture into the skin, a solvent to help blend ingredients, and a preservative booster to improve product shelf life.
Is pentylene glycol safe for sensitive skin?
While generally well-tolerated, some individuals with very sensitive skin might experience mild irritation from pentylene glycol, especially in higher concentrations. Patch testing is always recommended if you have sensitive skin.
