Best Description of EDTA Disodium Salt

EDTA Disodium Salt (Disodium ethylenediaminetetraacetate) is a white, crystalline, water-soluble chelating agent widely used in industrial, pharmaceutical, cosmetic, agricultural, and laboratory applications. It functions by binding with metal ions (such as calcium, magnesium, iron, and lead), forming stable, water-soluble complexes that prevent these metals from interfering with chemical processes or product stability.

Due to its excellent metal-chelating properties, EDTADisodium Salt plays a critical role in water treatment, detergents, personal care formulations, pharmaceuticals, and as an anticoagulant in blood sample collection. Its chemical formula is C??H??N?Na?O?·2H?O, and it is commonly available in both anhydrous and dihydrate forms.

Top 10 FAQs About EDTA Disodium Salt

What is EDTA Disodium Salt used for?
It is used as a chelating agent to bind metal ions in water treatment, cosmetics, pharmaceuticals, agriculture, and food processing.
Is EDTA Disodium Salt safe?
Yes, when used within regulatory limits, it is considered safe for industrial and pharmaceutical use. Food and cosmetic grades follow strict safety standards.
What is the difference between EDTA and EDTA Disodium?
EDTA refers to the base acid, while EDTA Disodium is a more soluble salt form, making it easier to use in water-based systems.
What industries use EDTA Disodium Salt?
Pharmaceutical, food processing, cosmetics, agriculture, textiles, and water treatment.
Is it water-soluble?
Yes, EDTA Disodium Salt is highly water-soluble, which makes it easy to incorporate in aqueous formulations.
How does EDTA work in cosmetics?
It binds metal ions to enhance product stability and prevent discoloration or spoilage.
Can EDTA Disodium be used in pharmaceuticals?
Yes, it is used to treat heavy metal poisoning and as a stabilizer in drug formulations.
Does EDTA act as a preservative?
Indirectly, yes. By binding metal ions, it enhances the effectiveness of preservatives and prevents microbial growth.
What forms does it come in?
It is available in powder, granules, and crystalline forms—usually in anhydrous or dihydrate variants.
Is EDTA biodegradable?
It is not readily biodegradable, so eco-friendly disposal practices are recommended in large-scale applications.
