Formula IngredientEmollientTriolein
INCI: Triolein
Triolein (INCI: Triolein) is a triglyceride composed of three oleic acid chains esterified to a glycerol backbone — chemically identical to the predominant triglyceride found in human sebum and many plant oils such as olive oil. It is used in cosmetics as an emollient and skin-conditioning agent, forming a lightweight, occlusive film on the skin surface that reduces trans-epidermal water loss and softens the feel of a formulation. Commercial cosmetic-grade triolein is often derived from microalgae through an eco-friendly biofermentation process, though it may also be sourced from oleic acid-rich vegetable oils.

Is Triolein safe? Key considerations
Can Triolein cause irritation?
Low RiskTriolein is not classified as a hazardous substance under GHS (291 of 291 ECHA C&L Inventory notifications report no hazard classification). No EU CosIng Annex II or III restrictions apply. It is well tolerated at typical cosmetic concentrations and is not associated with sensitisation or irritation in the published literature.
Does Triolein increase sun sensitivity?
No RiskTriolein has no known photosensitising mechanism. No special sun protection precautions are required based on its presence in a formulation.
Is Triolein safe during pregnancy?
SafeTriolein is a naturally occurring triglyceride present in human sebum and dietary fats. Topical use at cosmetic concentrations is considered safe during pregnancy. No reproductive or developmental concerns are noted in available safety databases.
