PEG/PPG-18/18 Dimethicone is a water-dispersible silicone surfactant used to emulsify, stabilize, and impart a smooth, silky feel to skincare and cosmetic formulations. It functions primarily as an emulsifier and skin-conditioning agent rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Occasional transient redness or stinging, typically in sensitive or compromised skin. |
| Allergic contact dermatitis | Very rare | Isolated sensitization reports; silicone surfactants are generally considered low-allergenicity. |
| Eye irritation | Uncommon | Can cause stinging or irritation on direct ocular contact in surfactant-containing products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
