Potassium Laureth Phosphate is an anionic surfactant and emulsifier used in cleansers and emulsions to help blend oil and water and provide mild cleansing. It functions as a formulation/base ingredient rather than a treatment active.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Uncommon | Transient stinging or redness, more likely with high concentrations or compromised skin barrier. |
Dryness or tightness | Uncommon | Possible with rinse-off cleansers due to surfactant action stripping surface lipids. |
Eye irritation | Uncommon | Stinging on accidental eye contact, typical of surfactants. |
Allergic contact dermatitis | Rare | Sensitization is infrequently reported; patch testing can confirm. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
