Polyglyceryl-4 Oleate
Ingredient Info
Polyglyceryl-4 Oleate is a gentle emulsifier and surfactant derived from plant-based glycerin and oleic acid (from oils). It helps mix water and oil-based ingredients together in skincare formulas and can improve how active ingredients penetrate the skin.
Benefits
- Helps stabilize skincare formulations
- Improves delivery of beneficial ingredients into skin
- Plant-derived emulsifier
- Supports barrier-strengthening ingredient absorption
Science: Research demonstrates that polyglyceryl-4 oleate acts as an effective co-surfactant in microemulsion systems, enhancing the stability of formulations and improving penetration of barrier-repair ingredients like ceramides into the stratum corneum (outer skin layer). Studies show it can increase formula shelf stability to 10+ months while maintaining superior ingredient delivery compared to conventional cream bases.
