Science
Mechanism of Action
POLYQUATERNIUM-103 acts by forming a stable interface in emulsion systems, preventing the separation of immiscible phases. Additionally, its physical properties contribute to the visual opacification of the final product, which can improve product aesthetics.

Dusting Analysis
This ingredient's primary roles are formulation-centric (emulsion stabilization, opacifying, viscosity control) rather than as a powdered active, so dusting is not a typical concern for consumer exposure beyond manufacturing.
