Triolein
Ingredient Info
Triolein is a natural oil derived from oleic acid (a monounsaturated fatty acid found in olive oil and other plant sources). In skincare formulations, it functions as an emollient and helps stabilize oil-water mixtures, contributing to product texture and moisture retention on the skin.
Benefits
- Emollient properties that soften and hydrate skin
- Helps formulations maintain stability and smooth texture
- Naturally derived ingredient with established use in cosmetics
Potential concerns
- May cause sensitivity in individuals with known oleic acid sensitivity
- Can undergo hydrolysis in high pH or alkaline formulations, potentially altering product stability
- Limited consumer-specific safety data; generally recognized as safe but not extensively studied in isolation for skincare use
Science: Recent research (2024) shows that triolein's behavior at oil-water interfaces is significantly affected by pH and buffer systems, with hydrolysis producing oleic acid at elevated pH levels. This suggests formulation pH is important for product stability and performance when triolein is included.
