PENTYLENE GLYCOL
Ingredient Info
Pentylene glycol is a humectant—a moisture-binding ingredient that helps skin retain water and feel hydrated. It's commonly used in skincare formulations to improve texture and maintain product stability.
Benefits
- Draws moisture into the skin for improved hydration
- Helps products feel smoother and lighter on the skin
- Contributes to product preservation and stability
Potential concerns
- May cause contact allergic reactions in sensitive individuals—classified as an emerging cosmetic allergen
- Rare cases of contact dermatitis have been reported
Science: Safety studies show pentylene glycol has a high margin of safety in typical skincare use, with low skin penetration due to its volatility. However, recent dermatological literature identifies it as an emerging allergen capable of causing contact sensitivity in some individuals, so patch testing is recommended for those with sensitive or reactive skin.
