Tetrasodium EDTA
v
Tetrasodium EDTA is the tetrasodium salt of ethylenediaminetetraacetic acid, a powerful chelating agent widely used in industrial, personal care, and pharmaceutical applications. It effectively binds metal ions such as calcium and magnesium, preventing their interference in formulations. Its ability to enhance stability, improve efficacy, and prevent microbial growth makes it a multifunctional ingredient in a variety of chemical products.
Primary Uses
Personal Care & Cosmetics
Stabilizer: Prevents metallic ions from destabilizing products like shampoos, conditioners, lotions, and creams.
Preservative Enhancer: Improves effectiveness of preservatives by binding metal ions that can fuel microbial growth.
Cleansing Agent: Enhances performance of surfactants and helps remove metal residue from skin and hair.
Cleaning Products
Chelating Agent: Used in household and industrial cleaners to soften water and improve cleaning efficacy.
Scale Inhibitor: Prevents buildup of mineral deposits on surfaces in detergents and dishwashing liquids.
Pharmaceuticals
Formulation Stabilizer: Ensures stability of active ingredients by sequestering metal ions.
Parenteral and Ophthalmic Solutions: Maintains product integrity and prevents precipitation.
Secondary Uses
Water Treatment
Metal Sequestration: Removes heavy metals and hardness ions in water softening and wastewater treatment processes.
Textile & Paper Industry
Bleaching Stabilizer: Prevents catalytic degradation of peroxide-based bleaching agents by binding metal contaminants.
Agriculture
Micronutrient Carrier: Forms stable complexes with metal micronutrients in fertilizers and soil conditioners.
Photography & Film
Solution Stabilizer: Used in photographic processing to maintain chemical balance and image quality.
