PEG-150 (polyethylene glycol 150) is a water-soluble polymer used in cosmetic formulations primarily as a viscosity-increasing agent, emulsion stabilizer, and humectant. It is a formulation aid rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Generally well tolerated; occasional irritation more likely on compromised or broken skin. |
Allergic contact dermatitis | Rare | Sensitization to PEG compounds is uncommon but documented, particularly on damaged skin. |
Enhanced penetration of other ingredients | Uncommon | PEGs can increase skin permeability, potentially heightening sensitivity to co-formulated substances. |
Eye irritation | Rare | May cause transient stinging or irritation with direct ocular contact. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
