About
A polyglycerol ester of oleic acid derived from glycerine and approximately 25 moles of ethylene oxide, functioning as a solubiliser and emulsifier for oil-soluble ingredients in water-based cosmetic formulations.
PEG-25 glyceryl trioleate is a polyethoxylated glyceryl ester where glycerine is esterified with three oleic acid chains and the glycerol backbone carries approximately 25 ethylene oxide units. The PEG chain increases water solubility while the glyceryl trioleate provides emulsification for lipophilic actives. EU CosIng lists PEG glyceryl fatty acid esters as safe for cosmetic use with no restrictions at typical use concentrations. The ingredient has a long history of use in topical pharmaceutical and cosmetic formulations. PEG fatty acid esters are considered low irritancy non-ionic surfactants, though residual free ethylene oxide must be controlled during manufacture per EU guidelines.
Skin benefits
- Solubilisation of oil-soluble fragrance and active ingredients
- Emollient effect from oleic acid component
- Improvement of skin feel and product texture
- Skin conditioning properties
Known concerns
- PEG component requires residual ethylene oxide/1,4-dioxane testing per EU cosmetic manufacturing standards
- Oleic acid may increase skin penetration of co-formulated ingredients
- Not suitable for damaged or highly sensitive skin at high concentrations
