Science
Mechanism of Action
This ingredient functions as an effective surfactant and emulsifying agent, characterized by its amphiphilic structure containing both lipophilic (oil-attracting) and hydrophilic (water-attracting) segments. This allows it to significantly reduce interfacial tension between immiscible liquids, forming and stabilizing homogenous oil-in-water or water-in-oil emulsions. As a glycerin-based fatty acid ester, it can also support the skin's moisture retention, potentially contributing to a healthier skin barrier function.

Stability
While specific stability data for Polyglyceryl-10 Decahydroxystearate is limited, related polyglyceryl-10 esters demonstrate robust pH stability. For instance, Polyglyceryl-10 Stearate shows excellent resistance to salts and acids, and Polyglyceryl-10 Decaoleate exhibits superior stability across a broad pH range of 1 to 13 in nanoemulsions, suggesting similar resilience for this ingredient.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Polyglyceryl-10 Decahydroxystearate, part of a family of 274 polyglyceryl fatty acid esters, is safe for use in cosmetics when formulated to be non-irritating. No specific maximum concentration was provided for this exact ingredient by CIR. Furthermore, polyglycerol esters of fatty acids are generally recognized as safe (GRAS) by the FDA for certain food applications as emulsifiers or stabilizers.
