Overview
EDTA (Ethylenediamine Tetra Acetic Acid) is a synthetic amino acid formulation, that is widely accepted across as sequestering / chelating agent, for use in various industrial applications such as water treatment, F&B, Laboratory processes, cosmetics, textiles, etc. Chemtex's EDTA comes in a range of salt variants, viz., Tetrasodium, Disodium, Trisodium, Diammonium, Dipotassium Dihydrate and also only in pure acidic form.
The formulation reacts with metallic cations, forming a stable rigid compound and making it easily excretable from the application system. It is preferred over other chelating agents owing to its ability to form strong covalent bond with metallic ions as other inorganic contaminants may react with those metal ions, forming their own compounds.
Key Features and Benefits
- Prompt action; Optimum chelating efficiency
- Exhibits slime dispersing property
- Does not contain added fragrance
- Broad spectrum application
