Science
Mechanism of Action
This ester functions by significantly lowering the interfacial tension between immiscible liquids, such as oil and water, thereby enabling the formation and stability of emulsions. As a surfactant, it aids in reducing surface tension, promoting even product distribution on the skin. Additionally, its emollient properties contribute to improved skin hydration and fortification of the skin's natural barrier function, all without inducing irritation. It further contributes to desirable product texture and can facilitate the solubilization of other cosmetic components.

Stability
Polyglyceryl-8 C12-20 Acid Ester is insoluble in water but readily disperses in oils and certain organic solvents. It exhibits good thermal stability, remaining stable below 100 °C under neutral conditions, and demonstrates resilience to acids and salts. However, the ester linkage is susceptible to accelerated hydrolysis in the presence of strong acids or bases.
