Edetate sodium tetrahydrate

Edetate sodium tetrahydrate (CAS 13235-36-4), also known as EDTA tetrasodium salt tetrahydrate, is a fully neutralized, water-soluble chelating agent.

Where is Edetate sodium tetrahydrate used?

• Personal care and cosmetics: stabilizes emulsions and preservative systems by deactivating trace metals
• Water treatment: controls scale formation and removes metal deposits from process equipment
• Textile and paper processing: prevents metal-catalyzed degradation of bleaching baths and dye formulations
• Food-grade applications: sequesters metal contaminants in canned and processed foods to protect flavor and color
• It binds and sequesters metal ions such as calcium, magnesium, iron, and heavy metals.

Good to know: It prevents metal ions from interfering with formulation stability, process efficiency, or product quality; in personal care, trace metals would otherwise accelerate oxidation or reduce antimicrobial efficacy.
