Science
Mechanism of Action
This ingredient functions by providing the skin with exogenous lipids, thereby strengthening the skin barrier and significantly improving moisture retention to prevent transepidermal water loss. It also exhibits properties that protect against inflammation and enhance the lipid content in the upper skin layers, mitigating dryness. As a surfactant and emulsifying agent, it reduces the interfacial tension between oil and water, ensuring the stability of emulsions and promoting product spreadability and absorption.

Stability
Polyglycerol esters generally exhibit good resistance to both acidic conditions and salts, contributing to robust product stability. The concentration of the emulsifier is a crucial factor influencing emulsion stability.
Safety
Safety Profile
The Expert Panel for Cosmetic Ingredient Safety (CIR) comprehensively assessed 274 polyglyceryl fatty acid esters, including Palm Oil Polyglyceryl-5 Esters, deeming them safe for cosmetic use under current practices and concentrations, provided they are formulated to be non-irritating. A 2-year dietary study in rats utilizing 5% polyglyceryl ester showed no carcinogenic or adverse effects, reinforcing its safety profile. Recommended use levels are typically ≤10%.
