FEATURES
General Properties: Food/pharma-grade antimicrobials (e.g., sodium benzoate, potassium sorbate, parabens); typically white crystalline powders or clear liquids.
Synergistic Role: In high-sugar or nutrient-rich liquids, minor microbial activity or high-shear mixing can cause foaming. The defoamer must be chemically inert, ensuring it does not react with, absorb, or deplete the active antimicrobial ingredients.
Performance Benefits:
Maintains Antimicrobial Efficacy: Chemically compatible defoamers ensure the preservative's active ingredients are not neutralized or depleted by the defoamer carrier.
Eliminates Bio-Foam: Rapidly collapses sticky, hard-to-break foam caused by minor microbial activity, fermentation byproducts, or protein degradation.
Extends Shelf-Life Stability: By preventing foam overflow and maintaining a sterile, homogeneous environment, it supports the overall preservation and quality system of the product.
