Science
Mechanism of Action
This ingredient operates primarily as a non-ionic emulsifying agent by acting as a surfactant, which reduces the surface tension between immiscible liquids like oil and water, facilitating their uniform dispersion and stability. It also aids in skin conditioning, enhancing texture and hydration by dissolving oils and waxes and promoting the formation of beneficial liquid crystalline structures on the skin. Furthermore, Polyglyceryl-5 Oleate can impart a velvety skin feel, deliver long-lasting moisturization, and enhance the absorption of other active ingredients.

Stability
Polyglyceryl-5 Oleate exhibits excellent stability across varying temperatures, demonstrating robust heat and cold resistance particularly in water-in-oil cream formulations. It also possesses high resistance to electrolytes, contributing to stable product integrity. While pH can influence foam stability, a precise optimal pH range for the ingredient's overall stability is not extensively documented.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed polyglyceryl fatty acid esters, including Polyglyceryl-5 Oleate, safe for use in cosmetics when properly formulated to be non-irritating. No adverse effects were reported at test concentrations up to 5 wt% for polyglycerol esters. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) established an Acceptable Daily Intake (ADI) of 0-25 mg/kg body weight for polyglycerol esters of fatty acids.
