In our reference data, Sodium Oleate can feed Malassezia (fungal acne).
Sodium oleate is the sodium salt of oleic acid, a soap-type anionic surfactant used as a cleansing agent, emulsifier, and foaming component in skincare and personal care formulations. It helps disperse oils and stabilize emulsions rather than acting as a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation/dryness | Common | As a soap-based surfactant it can disrupt the skin barrier and cause dryness or mild irritation, especially with frequent use or high concentrations. |
| Contact dermatitis | Uncommon | Irritant or, less often, allergic contact reactions reported in sensitive individuals. |
| Comedogenicity/follicular reactions | Uncommon | Oleate derivatives may contribute to clogged pores in acne-prone skin in some reports. |
| Allergic sensitization | Rare | True allergic hypersensitivity to the ingredient is infrequently documented. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
