Science
Mechanism of Action
This ingredient forms chelate complexes, which facilitate particle cohesion in powder-based products, preventing separation. In emulsions, it acts as a stabilizer by cross-linking with resins like epoxy, silicone, or acrylic, improving adhesion and film-forming properties.
