Product Overview
EDTA Tetrasodium Salt, also known as EDTA-4Na, is an alkaline EDTA chelating agent commonly used for metal ion control and hard water management in detergents, cleaning products, industrial cleaning, water treatment, and industrial formulation systems. It is usually supplied as a white crystalline powder, and buyers often review purity, pH, solubility, appearance, alkalinity, moisture, and batch documents before technical or commercial evaluation. It is commonly considered for alkaline cleaning systems, detergent formulations, water hardness control, and industrial aqueous processes, with COA, SDS/MSDS, TDS, sample discussion, and export packing support available for sourcing reference.

Applications
Detergents & Cleaning Products
EDTA Tetrasodium Salt is commonly evaluated in detergent, cleaner, and household cleaning formulations where hard water control and metal ion binding are required. It is especially relevant for alkaline systems where chelation performance and formulation stability are important.
Industrial Cleaning
For industrial cleaning products, EDTA-4Na may be reviewed for water hardness management, metal ion control, and cleaning system performance. Buyers should confirm pH fit, compatibility with surfactants, builders, and other alkaline components before bulk use.
Water Treatment
EDTA Tetrasodium Salt can be considered for water treatment and aqueous process systems where metal ion binding, scale control, or process stabilization is required under alkaline conditions. Final suitability depends on dosage, pH range, water composition, and technical requirements.
Industrial Formulations
EDTA-4Na may be used in textile, metal processing, chemical blending, and industrial formulation systems where alkaline chelation, stabilization, or metal ion control is needed. Buyers should review compatibility, purity, and document requirements before approval.
How to Choose the Right Grade / Form
For detergent applications
Review purity, pH, solubility, alkalinity, compatibility with surfactants, and performance in the final detergent system. EDTA-4Na is usually selected when alkaline chelation and hard water control are important.
For industrial cleaning systems
Confirm pH fit, chelation requirement, water hardness conditions, builder compatibility, and final cleaning performance expectations. Pilot testing is recommended when EDTA-4Na is used in concentrated or highly alkaline systems.
For water treatment or industrial use
Check purity, pH, solubility, moisture, packaging, handling, and technical documentation. Application testing is recommended when EDTA-4Na is used in complex aqueous, textile, metal processing, or industrial systems.
Technical & Formulation Notes
Technical Notes
Technical Notes
EDTA Tetrasodium Salt is evaluated when buyers need an EDTA chelating agent suitable for alkaline systems and hard water control. Key technical review points usually include purity, pH, solubility, alkalinity, appearance, moisture, compatibility with the target cleaning or industrial system, and document support.
Manufacturing & Process
Manufacturing & Process
The commercial product is typically supplied as a dry crystalline powder through controlled neutralization, crystallization, drying, and packaging steps. Buyers should confirm the agreed specification, physical form, pH range, solubility, and packaging requirements before order confirmation.
Compatibility / Formulation Notes
For detergent systems, confirm pH fit, dosage level, surfactant compatibility, and final cleaning performance before bulk use.
For alkaline cleaning products, review compatibility with builders, caustic components, surfactants, and target water hardness conditions.
For water treatment systems, confirm dosage, water composition, pH range, and process compatibility during pilot testing.
For industrial aqueous systems, review solubility, alkalinity, metal ion load, process temperature, and interaction with other formulation components.
Store sealed and protected from moisture, contamination, and incompatible materials during handling.
Extended QC & Test Items
Extended QC & Test Items
Extended quality review may include assay or purity, identification, pH, solubility, moisture or loss on drying, heavy metals, appearance, and batch-to-batch consistency. For detergent, cleaner, water treatment, or industrial projects, additional specification review can be discussed according to the application system and destination market.
