In our reference data, PEG-4 Laurate can feed Malassezia (fungal acne).
PEG-4 Laurate is a polyethylene glycol ester of lauric acid used in cosmetics as a nonionic emulsifier, surfactant, and emollient that helps blend oil and water phases and improve product texture. It is a formulation/base ingredient rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Uncommon | Possible transient redness or stinging, more likely on compromised or sensitive skin. |
| Allergic contact dermatitis | Rare | Sensitization to PEG compounds is reported but infrequent. |
| Increased penetration of other ingredients | Uncommon | As a surfactant it may enhance absorption of co-formulated substances, indirectly increasing irritation potential. |
| Eye irritation | Uncommon | Possible with direct contact in surfactant-containing rinse-off or cleansing products. |
| Concern over trace impurities (e.g., 1,4-dioxane, ethylene oxide) | Very rare | Process-related contaminants possible if not adequately purified; mitigated by manufacturing controls. |
