Sophorolipid is a glycolipid biosurfactant produced by yeast fermentation (notably Starmerella bombicola) that acts as a mild cleanser, emulsifier, and antimicrobial agent in cosmetic formulations. It is valued as a biodegradable, plant- or fermentation-derived alternative to synthetic surfactants.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation or transient redness | Uncommon | Generally considered milder than conventional synthetic surfactants, but possible at higher concentrations. |
| Dryness or barrier disruption with overuse | Uncommon | As with any surfactant, excessive or prolonged exposure may reduce skin lipids. |
| Allergic contact dermatitis | Rare | Sensitization is infrequently reported; patch testing advised for sensitive individuals. |
| Stinging on application to compromised skin | Rare | More likely on broken or already irritated skin. |
