Science
Mechanism of Action
As a polyethylene glycol diester derived from isostearic acid, this ingredient operates by significantly reducing surface tension, thereby acting as a powerful surfactant. It functions as an emulsifying agent, facilitating the stable integration of disparate oil and water phases within a formulation. Additionally, it provides skin conditioning effects, enhancing the overall feel and appearance of the skin.

Stability
This ingredient is formed through the PEGylation of Glyceryl Diisostearate, involving the incorporation of 20 units of ethylene oxide across the glycerin core's alcohol groups and into the two isostearic esters. This structural characteristic contributes to its functionality within formulations.
