Overview
Dipotassium EDTA (CAS 2001-94-7 ) is a potassium salt of ethylenediaminetetraacetic acid used industrially as a chelating and sequestering agent. It binds free metal ions in solution, preventing them from catalyzing oxidation, scale formation, or product degradation.
Buyers source it as a water-soluble alternative to sodium-based EDTA salts where potassium content is a formulation requirement. In personal care and cosmetics, it stabilizes formulations by deactivating trace metals that would otherwise accelerate rancidity.
This chemical prevents the discoloration of finished products by managing metal ion activity. Water treatment operations use it to sequester calcium, magnesium, and heavy metal ions, improving process efficiency and preventing mineral deposits in industrial systems.
Agricultural applications include its use as a chelating carrier that keeps micronutrient minerals bioavailable in fertilizer blends and foliar sprays. This ensures that essential nutrients remain accessible to plants even in challenging soil conditions.
In textile and leather processing, it controls metal ion interference during dyeing and finishing, improving color consistency and process control. This leads to higher quality outputs and more predictable manufacturing results across various production cycles.
The product is supplied as a white crystalline powder or granule. It is available in technical grade for industrial applications and in higher-purity grades meeting specifications relevant to cosmetic and food-contact uses.
Packaging typically ranges from small drums to bulk quantities depending on application volume. Our supply chain ensures consistent quality and availability for large-scale industrial requirements and specialized laboratory applications alike.
