Science

Mechanism of Action

This ingredient primarily enhances the skin barrier by supplying exogenous lipids, which are vital for maintaining skin integrity and moisture retention. This action leads to improved skin hydration and contributes to protection against inflammation. Concurrently, it functions as an emulsifier, stabilizing diverse cosmetic formulations by effectively blending immiscible phases.

Stability

Polyglyceryl fatty acid esters generally exhibit good thermal stability under neutral conditions, maintaining integrity below 100 °C. However, their ester linkages are susceptible to hydrolysis, which can be significantly accelerated by the presence of strong acids or strong bases. Degradation can also occur via the action of lipases.
