In our reference data, PEG-75 Stearate can feed Malassezia (fungal acne).
PEG-75 Stearate is a polyethylene glycol ester of stearic acid used as a nonionic emulsifier, surfactant, and emollient in skincare and cosmetic formulations. It helps blend oil and water phases and improves product texture.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Uncommon | Possible transient redness or stinging, more likely on compromised or sensitive skin. |
| Contact dermatitis / allergic sensitization | Rare | PEG derivatives can rarely trigger allergic reactions, particularly on broken skin. |
| Increased penetration of other ingredients | Uncommon | As a surfactant it may enhance absorption of co-formulated substances, indirectly affecting tolerance. |
| Trace impurity concerns (1,4-dioxane, ethylene oxide) | Very rare | Theoretical concern from PEG manufacturing; mitigated by purification in cosmetic-grade material. |
