Science
Mechanism of Action
This ingredient operates through its unique molecular architecture, featuring a hydrophilic polyglyceryl backbone and multiple hydrophobic oleic acid chains. This structure allows it to significantly reduce interfacial tension, forming robust, uniform emulsions crucial for product stability and texture. On the skin, it contributes to hydration, promoting a softer, smoother, and more elastic feel. It is also recognized for its gentle interaction with the skin, supporting the integrity of the natural lipid barrier and potentially enhancing the dermal uptake and even distribution of other active ingredients.

Formulation
Stability
Polyglyceryl-10 Pentaoleate is a lipophilic, nonionic surfactant adept at creating stable water-in-oil (W/O) emulsions, making it ideal for richer creams and milky lotions. Its balanced Hydrophilic-Lipophilic Balance (HLB) is key to forming these consistent emulsions. While an exact optimal pH range is not specified, polyglyceryl esters are generally noted for good overall stability in cosmetic applications.
