Request SDS →Disodium EDTA (disodium edetate, CAS 139-33-3) is the disodium salt of ethylenediaminetetraacetic acid, used as a chelating and sequestering agent. It binds trace metal ions to stabilize formulations, retain color, and support preservative systems in personal care and industrial products. It is also used in pulp and paper processing and in textile dyeing and finishing.
Frequently Asked Questions
What is disodium EDTA used for?
Disodium EDTA (disodium edetate) is a chelating and sequestering agent that binds trace metal ions to stabilize formulations, retain color, and support preservative systems in personal-care and industrial products. It is also used in pulp and paper processing and in textile dyeing and finishing.
What is the difference between EDTA and disodium EDTA?
EDTA is the free acid, ethylenediaminetetraacetic acid; disodium EDTA (CAS 139-33-3, C10H14N2Na2O8) is its disodium salt, which is more water-soluble and near-neutral in solution. Other salts (tetrasodium, calcium-disodium) also exist — confirm the CAS on the CoA.
Is disodium EDTA water soluble?
Yes. Disodium EDTA is appreciably water-soluble, which is why the disodium salt is preferred over the free acid for aqueous chelation. Exact solubility and assay are documented on the CoA supplied with each lot.
What is the CAS number and HS code for disodium EDTA?
CAS 139-33-3, molecular formula C10H14N2Na2O8; it classifies under HS 2922.49 (other amino-acids and their derivatives). Identity is confirmed on the CoA, with a current SDS per shipment.
How is disodium EDTA supplied in bulk?
It is supplied as a crystalline/granular powder in bags, supersacks, or drums to formulators and industrial buyers. Available grades and pricing depend on volume and destination; submit a bulk RFQ for a quote, CoA, and SDS.
