Thickeners

 General Properties: Hydrocolloids and cellulose derivatives (e.g., CMC, HPMC, pectin, carrageenan); typically white, free-flowing powders that form highly viscous, clear solutions.

 Synergistic Role: The thick, viscous network prevents trapped air from rising to the surface. The defoamer must possess exceptional spreading and penetrating power to navigate the high-viscosity matrix, rupture the bubble walls, and release the entrapped air.

 Performance Benefits:

Overcomes High Viscosity: Effectively breaks micro-foam even in highly thickened, gel-like food and pharma systems.

Ensures Visual Clarity: Removes tiny suspended air bubbles that cause cloudiness or opacity in clear syrups, gels, and beverages.

Improves Processability: Deaerates the thick liquid, preventing pump cavitation and ensuring smooth, continuous, and drip-free flow through filling nozzles.
