Science
Mechanism of Action
This ingredient operates as an effective emulsifier, facilitating the creation of stable emulsions by uniformly dispersing oil within water or vice versa, thereby optimizing product consistency. On the skin, it acts as an emollient, delivering significant moisturizing and softening effects. Furthermore, it plays a crucial role in reinforcing the skin's inherent moisture barrier, offering enhanced protection against dehydration and adverse environmental factors.

Formulation
Stability
Polyglyceryl-2 Isopalmitate/Sebacate is highly soluble in oils and various organic solvents, demonstrating limited solubility in water, a characteristic crucial for its amphiphilic emulsifying capabilities. It exhibits robust thermal stability under neutral conditions at temperatures below 100 °C. This ingredient effectively forms and stabilizes both oil-in-water and water-in-oil emulsions, supporting the integrity of complex formulations. It is compatible with cold processing methods and blends well with both natural and synthetic thickeners.
