Isopentyldiol
Ingredient Info
Isopentyldiol (IPDO) is a humectant—a moisture-binding ingredient that helps skin retain water and stay hydrated. It's a small organic compound used in cosmetics primarily for its ability to support skin hydration and may help stabilize other ingredients in formulations.
Benefits
- Helps skin retain moisture and maintain hydration
- May support skin barrier function and cellular integrity
- Functions as an osmolyte, helping cells maintain balance under stress
Science: Recent research identifies isopentyldiol as an osmolyte—a compound that helps protect cellular structures under stress conditions (UV, temperature, pH changes). However, peer-reviewed cosmetic efficacy data is limited; most published evidence focuses on its industrial production rather than consumer skincare performance.
