Edetate sodium tetrahydrate

Edetate sodium tetrahydrate (CAS 13235-36-4), commonly known as EDTA tetrasodium salt tetrahydrate, is a fully neutralized, water-soluble chelating agent used across industrial and consumer product manufacturing. It binds and sequesters metal ions such as calcium, magnesium, iron, and heavy metals. This prevents them from interfering with formulation stability, process efficiency, or overall product quality during manufacturing.

In personal care and cosmetics, it stabilizes emulsions and preservative systems by deactivating trace metals. These metals would otherwise accelerate oxidation or reduce the efficacy of antimicrobial systems in the product. Water treatment operations use it to control scale formation and remove metal deposits from process equipment. This ensures the longevity and efficiency of distribution systems in various industrial environments.

In textile and paper processing, it prevents metal-catalyzed degradation of bleaching baths and dye formulations. This improves color consistency and yield while protecting the integrity of the final materials. Food-grade applications include sequestering metal contaminants in canned and processed foods to protect flavor and color. This helps maintain shelf life and meets the strict requirements of the food industry.

Edetate sodium tetrahydrate is supplied as a white crystalline powder or granules. It is available in food-grade (FCC), USP, and technical grades to meet the specification requirements of different industries. Bulk packaging in bags and drums is standard for this material. Industrial quantities are available for large-scale procurement to support high-volume manufacturing and chemical processing operations.
