Disodium EDTA

General Description
Disodium EDTA (Disodium Ethylenediaminetetraacetate) is a classic, high-efficiency chelating agent and stabilizer extensively used in the personal care, food, and pharmaceutical industries. It is the industry standard for sequestering trace metal ions to ensure formulation integrity, longevity, and safety.

Mechanisms of Action

• Potent Chelation (Sequestration):
  Forms stable, water-soluble complexes with trace heavy metal ions (e.g., iron, copper, calcium). By inactivating these ions, it prevents them from catalyzing lipid oxidation (rancidity) and degrading active ingredients, effectively protecting the formulation at its source.

• Preservative Synergy:
  Destabilizes the cell walls of microorganisms by depriving them of essential metal ions. This action significantly enhances the efficacy of antimicrobial preservatives, boosting the overall preservation system and inhibiting microbial proliferation.

• System Stabilization:
  Mitigates the negative effects of hard water and metal ions on surfactants and emulsifiers, thereby preventing precipitation, stratification, and syneresis (water separation).

Key Benefits

• Ingredient Protection & Efficacy:
  Prevents the discoloration, oxidation, and degradation of sensitive active ingredients, fragrances, and essential oils, ensuring the product retains its intended efficacy and sensory profile.

• Shelf Life Extension:
  Significantly prolongs product shelf life by averting chemical deterioration and spoilage caused by metal-catalyzed reactions.

• Stability Assurance:
  Maintains the physicochemical stability of the formula, preventing changes in viscosity or appearance over time.

Applications & Compatibility

• Target Industries: Personal Care (Skincare, Hair Care, Toiletries), Food & Beverage, and Pharmaceuticals.

• Formulation Suitability: Universally compatible with water-based systems. A critical stabilizer for soaps, lotions, shampoos, and liquid formulations.

• Primary Functions: Chelating Agent/Sequestrant, Stabilizer, Preservative Synergist, Antioxidant Aid.
