EDTA Calcium Disodium Purity 99 White Crystalline Powder

product informations:

• Chemical Name: Ethylenediaminetetraacetic acid calcium disodium salt hydrate
• International Nomenclature: Calcium Disodium EDTA / Food Additive E385
• CAS Number: 62-33-3
• Molecular Formula: C₁₀H₁₂CaN₂Na₂O₈⋅ xH₂O
• Appearance: Free-flowing, odorless white crystalline powder
• Solubility: Highly soluble in water; practically insoluble in organic solvents
• Purity Assay: ≥ 98.0% to 101.0% on an anhydrous basis
• pH Value: 6.5 – 7.5 (1% aqueous solution)

• Heavy Metal Chelation: Forms exceptionally stable, water-soluble complexes with trace heavy metal ions such as iron (Fe²⁺/Fe³⁺), copper (Cu²⁺), manganese (Mn²⁺), and zinc (Zn²⁺).
• Oxidation Inhibition: Prevents metal-catalyzed oxidation reactions that lead to rancidity, flavor degradation, and nutrient loss in organic formulations.
• Color and Texture Retention: Safeguards natural pigments and structural binders from breaking down when exposed to trace processing minerals or environmental elements.
• Synergistic Preservation: Enhances the efficiency of traditional antimicrobial preservatives, maximizing microbial stability across varied pH ranges.

• Beverages and Carbonated Drinks: Prevents the degradation of vitamin C (ascorbic acid) and inhibits benzene formation catalyzed by trace metals.
• Canned Goods and Pickled Vegetables: Retains the natural color, crispness, and visual appeal of mushrooms, beans, potatoes, and pickled cucumbers during long-term storage.
• Condiments, Dressings, and Mayonnaise: Stabilizes unsaturated fats and oils against oxidative rancidity, preserving taste profiles and preventing emulsion separation.
• Seafood Processing: Curbs the development of off-odors, discoloration, and structural softening in processed shellfish and canned fish products.

• Formulation Stabilizer: Protects sensitive ingredients like vitamins, essential oils, and botanical extracts from mineral-induced degradation in creams and lotions.
• Clarity Maintenance: Prevents cloudiness, precipitation, and sediment formation in clear liquid soaps, shampoos, gels, and micellar waters.
• Hard Water Protection: Counteracts the lather-killing effects of calcium and magnesium ions in tap water, enhancing cleansing performance and sensory feel.

• Stabilizing Excipient: Secures the stability of active pharmaceutical ingredients (APIs) in liquid formulations, eye drops, and injectable solutions.
• Anticoagulant Manufacturing: Serves as a vital additive in medical vacuum blood collection tubes to preserve blood cell morphology.

• Micronutrient Fertilizers: Acts as a superior carrier for calcium micronutrient delivery in foliar sprays and hydroponic nutrient solutions.
• Industrial Water Treatment: Eliminates scale buildup and heavy metal interference in high-precision textile, printing, and cleaning processes.

• Exceptional Thermal Stability: Remains chemically stable and biologically inert during high-temperature food pasteurization, UHT sterilization, and autoclaving processes.
• Broad pH Adaptability: Maintains robust chelation capacity across a wide pH spectrum, making it versatile for both acidic beverages and neutral skincare emulsions.
• Superior Batch Consistency: Manufactured under rigorous GMP standards to ensure ultra-low heavy metal impurities (Lead ≤ 1 ppm, Arsenic ≤ 1 ppm).
• Cost-Effective Efficiency: Delivers powerful stabilization results at remarkably low usage levels, typically ranging from 30 ppm to 250 ppm depending on application boundaries.

• Global Compliance: Fully meets the strict standards of the Food Chemicals Codex (FCC), United States Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur.), and JECFA regulations.
• Regulatory Status: Recognized as Generally Recognized as Safe (GRAS) by the US FDA for specific food applications and fully approved as E385 within the European Union.
• Packaging Solutions: Available in standard 25 kg multi-layer kraft paper bags with PE inner liners, or customizable jumbo bags (500 kg/1000 kg) to fit automated industrial dispensing lines.
• Storage Guidance: Store in a cool, dry, well-ventilated warehouse. Keep containers tightly sealed to protect the hygroscopic powder from atmospheric moisture and direct sunlight.
• Shelf Life: Minimum of 24 months from the date of manufacture when stored properly under recommended warehouse conditions.
