Sodium Calcium Edetate
Formula:
C10H12CaN2Na2O8
GOST/CAS:
CAS 62-33-9 / 23411-34-9
Sodium Calcium Edetate (Calcium Disodium EDTA, complexing reagent) is a highly effective chelating agent of pharmacopoeial quality. The product is a white, odorless crystalline powder that is readily soluble in water. Due to its outstanding ability to bind heavy metal ions into stable, water-soluble complexes, it serves as an indispensable component in pharmaceutical manufacturing, medicine, premium-class personal care formulations, household cosmetics, and advanced auto care products.
Applications
Pharmaceuticals & Medicine: Acts as an antidote for heavy metal poisoning (lead, cobalt, cadmium, etc.). It is widely used as a stabilizer and preservative in injectable solutions, eye drops, and ointments to prevent the oxidation of active ingredients induced by trace metals.
Cosmetics & Personal Care: Functions as a synergestic agent for preservatives and antioxidants in liquid soaps, shampoos, and shower gels. It softens water and protects the product's organoleptic properties (color, odor, clarity) from degrading during shelf life.
Household & Auto Chemicals: A key ingredient in liquid detergents designed to remove lime scale, rust, and mineral deposits. Used in professional cleaning solutions and car shampoos to maximize surfactant stability in hard water.
Textile & Leather Industries: Utilized to bind metal ions during fabric dyeing and leather tanning processes, successfully preventing staining and ensuring uniform color distribution.
Key Advantages
High Chelating Capacity: Effectively binds calcium, magnesium, iron, and heavy metal ions across a wide pH range, preventing their negative impact on the final product's stability.
Synergy with Preservatives: Disrupts bacterial cell membranes by binding the essential metal ions required for microbial life, significantly boosting preservative efficacy and reducing the required dosage.
Pharmaceutical Purity (Pharma Grade): High purity levels and strict compliance with GMP guidelines and global pharmacopoeia standards guarantee absolute safety for medical and cosmetic applications.
Enhanced System Stability: Prevents precipitation, haziness in solutions, and surfactant degradation, ensuring the product maintains its premium presentation and properties throughout its shelf life.
