EDTA- ▸ Chelating agent: Sequesters calcium, magnesium, iron, and trace metals.
- ▸ Detergent additive: Builder and stabilizer in cleaning formulations.
- ▸ Water treatment: Hardness and metal-ion control.
- ▸ Pulp and paper: Metal sequestration in bleaching and processing.
- ▸ Food preservation: Antioxidant synergist and sequestrant (JECFA-classified).
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Ethylenediaminetetraacetic acid (CAS 60-00-4) is a hexadentate aminopolycarboxylic acid and one of the most widely used chelating agents. It binds calcium, magnesium, iron, and other metal ions to control hardness, prevent metal-catalyzed degradation, and sequester trace metals across detergents, water treatment, pulp and paper, textiles, and food preservation.
Frequently Asked Questions
What is ethylenediaminetetraacetic acid used for?
EDTA (CAS 60-00-4) is a hexadentate chelating agent that binds calcium, magnesium, iron, and other metal ions. Industrial uses include hardness and metal-ion control in detergents and water treatment, metal sequestration in pulp and paper bleaching, and use as a sequestrant in textiles and food preservation.
What is another name for ethylenediaminetetraacetic acid?
It is commonly abbreviated EDTA and also known as edetic acid. Related supplied forms include its disodium salt (disodium EDTA) and disodium salt dihydrate. The base acid is CAS 60-00-4, formula C10H16N2O8.
Is EDTA water soluble?
The free acid form of EDTA has limited water solubility, which is why it is frequently supplied and used as its more soluble salts (e.g., disodium or tetrasodium EDTA) in liquid formulations. Specify the form you need when requesting a quote.
What grades and forms of EDTA does RawSource supply?
EDTA is available as the free acid and as common salt forms (disodium, disodium dihydrate). Available grades and forms vary by lot and supplier; confirm the exact grade, salt form, and CoA specifications when requesting a quote.
What is the cost of bulk EDTA?
Bulk pricing depends on the form (acid or salt), volume, packaging, and delivery location. RawSource supplies industrial quantities — request a quote with your target form, volume, and CoA/SDS requirements for delivered pricing.
