Science
Mechanism of Action
This ingredient operates through several key mechanisms: As an emollient, it effectively integrates into the stratum corneum, bridging gaps between corneocytes to create a visibly smoother skin surface. This action also fortifies the skin's natural barrier, significantly diminishing transepidermal water loss and enhancing hydration. As an emulsifier, it plays a critical role in stabilizing oil and water phases within formulations, ensuring uniform consistency and preventing separation. Furthermore, its surfactant properties enable it to lower surface tension, facilitating the dispersion and removal of sebum, environmental pollutants, and other impurities from the skin's surface.

Stability
Polyglyceryl fatty acid esters, including Polyglyceryl-2 Myristate, demonstrate robust stability, notably resisting oxidation. These compounds are instrumental in maintaining the stability and homogeneity of cosmetic formulations by efficiently binding hydrophilic and lipophilic ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel thoroughly evaluated a comprehensive class of 274 polyglyceryl fatty acid esters, including Polyglyceryl-2 Myristate. The panel deemed these ingredients safe for cosmetic application, provided they are formulated to be non-irritating under current industry practices. While no specific maximum concentration was identified for Polyglyceryl-2 Myristate, its safety is affirmed within the context of responsible formulation.
