Science
Mechanism of Action
This ingredient functions as an effective emulsifier and surfactant, expertly stabilizing oil-in-water or water-in-oil emulsions and preventing component separation. It also acts as a solubilizer, facilitating the dissolution and dispersion of various hydrophobic elements such as oils, dyes, and fragrances. On the skin, it serves as a conditioning agent and emollient, perceptibly enhancing skin texture and appearance by contributing to a softer, smoother, and more hydrated feel.

Formulation
Stability
Polyglyceryl-8 Isostearyl Ether exhibits robust thermal stability, generally remaining stable below 100 °C, especially under neutral pH conditions. However, its ester linkages are susceptible to accelerated hydrolysis when exposed to strong acids or bases, which can compromise the long-term stability of the formulation.
