Triolein is a triglyceride composed of glycerol esterified with three oleic acid molecules, used in skincare as an emollient and occlusive that softens skin and helps reduce transepidermal water loss. It also serves as a lipophilic solvent and texture enhancer in oil-based and emulsion formulations.
| Reported effect | How often | Notes |
|---|---|---|
Comedogenicity (pore-clogging) in acne-prone skin | Uncommon | Oleic acid-rich lipids may contribute to follicular occlusion in predisposed individuals. |
Mild skin irritation or stinging | Rare | Generally well tolerated; irritation more likely with compromised skin barrier. |
Allergic contact dermatitis | Very rare | Sensitization to triglyceride-based ingredients is infrequently reported. |
