In our reference data, Sodium Stearate can feed Malassezia (fungal acne).
Sodium stearate is the sodium salt of stearic acid, commonly used as an emulsifying agent, thickener, and gelling/structuring agent in soaps, sticks, and creams. It primarily serves a formulation role rather than providing a therapeutic active effect.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Uncommon | Mild irritation possible, particularly in high-pH soap formulations or on sensitive skin. |
| Skin dryness | Uncommon | As a soap-based surfactant it can disrupt the skin barrier and reduce moisture with frequent use. |
| Allergic contact dermatitis | Rare | Sensitization is infrequent; reactions may relate to associated fatty-acid impurities. |
| Eye irritation | Uncommon | Can cause stinging or irritation on direct ocular contact in cleansing products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
