Science
Mechanism of Action
This ingredient effectively stabilizes emulsions by facilitating the uniform dispersion of immiscible oil and water phases. On the skin, it forms a light, protective film that softens and smooths the surface, actively preventing moisture loss and reinforcing the skin barrier. Its molecular structure combines the humectant properties of polyglycerin-3 with the emollient characteristics of palmitic acid, delivering a dual benefit of hydration and skin conditioning. Additionally, it possesses surfactant qualities, enabling gentle foaming and cleansing action.

Stability
Polyglyceryl-3 Palmitate demonstrates excellent stability within a pH range of 4.0 to 8.0. Its emulsification performance is particularly robust under acidic conditions. Formulators should avoid exposing the ingredient to temperatures above 80°C during the mixing process to maintain its integrity.
Conflicts
- Accelerated hydrolysis by strong bases or acids due to its ester linkage
- Degradation by lipases
