In our reference data, PEG-32 Stearate can feed Malassezia (fungal acne).
PEG-32 Stearate is a polyethylene glycol ester of stearic acid used as a nonionic emulsifier, surfactant, and emollient to stabilize oil-in-water formulations and improve texture. It is a formulation base ingredient rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Uncommon | Generally well tolerated; transient irritation possible, more likely on compromised or broken skin. |
| Allergic contact dermatitis | Rare | Sensitization to PEG-based emulsifiers reported infrequently in patch-test studies. |
| Eye irritation | Uncommon | Can cause stinging or irritation on direct contact with eyes in rinse-off or leave-on products. |
| Enhanced penetration of other ingredients | Rare | As a surfactant it may increase skin permeability, theoretically affecting absorption of co-formulated substances. |
