Science
Mechanism of Action
This ingredient functions by significantly reducing the interfacial tension between immiscible oil and water components, thereby stabilizing emulsions and preventing phase separation. As a skin-conditioning agent, it actively contributes to softening and smoothing the skin's surface and supports the formation of a protective barrier. Its presence also improves the product's spreadability and overall feel. While specific studies are not provided for this particular ester, related polyglyceryl esters are known to offer moisturizing benefits and may enhance the penetration of other active ingredients.

The Formula
Formulation
Stability
Polyglyceryl-6 Hexastearate forms stable oil-in-water (O/W) emulsions and can contribute to liquid crystalline structures, significantly enhancing formulation stability. It exhibits excellent resistance to salts and acids and is non-aggressive, ensuring broad compatibility with diverse cosmetic ingredients. For optimal emulsion preparation, oil and aqueous phases should be heated separately to a temperature range of 70-80°C.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Polyglyceryl-6 Hexastearate, along with 273 other polyglyceryl fatty acid esters, safe for use in cosmetics under current practices and concentrations, provided formulations are non-irritating. Furthermore, polyglycerol esters of fatty acids (up to decaglycerol esters) are approved as food additives by the FDA, indicating a generally favorable safety profile for this ingredient family.
