Disodium EDTA

Product Description

Our Disodium EDTA is a high-grade chelating agent manufactured to ensure maximum stability for complex cosmetic systems. By sequestering heavy metal ions, it prevents the oxidation of active ingredients and maintains the scientific integrity of the formula's texture and color. In the B2B sector, it is recognized as a fundamental commercial additive for extending shelf life and enhancing preservative efficacy.

Product Specification

• Chemical Name: Disodium Ethylenediaminetetraacetate
• CAS No.: 139-33-3 / 6381-92-6
• Appearance: White crystalline powder
• Purity (Titration): ≥ 99.0%
• pH (5% solution): 4.0 – 6.0
• Solubility: Highly soluble in water

Key Benefits & Applications

• Heavy Metal Sequestration: Binds with traces of metal ions (like Iron and Copper) to prevent catalysis of lipid oxidation.
• Preservative Booster: Weakens bacterial cell walls by removing essential minerals, significantly enhancing the power of antimicrobial agents.
• Clarity Preservation: Prevents precipitation and turbidity in clear aqueous products like toners and shampoos.
• Applications: Cleansers, lotions, shampoos, and any water-based cosmetic formulation.

Formulation Guidelines

• Usage Level: 0.05% – 0.20%.
• Processing: Add directly to the aqueous phase at the beginning of the formulation process to ensure early chelation.
• Water Quality: Essential for formulations using "hard" water to prevent interference with surfactants.
• Synergy: Combine with Laurocapram to maintain the stability of penetration-enhanced formulas containing sensitive actives.
