Description
Additional Information
Main Uses
1. Water Treatment and Metal Ion Chelation
Hard water softening: Removes Ca2⁺ and Mg2⁺ from water to prevent scale formation, used for boiler feed water and detergent formulations (e.g., replacing phosphates in laundry powder);
Metal ion removal: Chelates heavy metal ions (e.g., Fe3⁺, Cu2⁺) in electroplating solutions to stabilize the bath composition; complexes heavy metals in industrial wastewater treatment to reduce their toxicity.
2. Food and Beverage Industry
Food additives (preservatives, antioxidants):
Chelates metal ions in food (e.g., Fe3⁺, Cu2⁺) to inhibit oxidation reactions and enzymatic browning, extending shelf life (e.g., used in canned goods, fruit juices, soy sauce);
National standard GB 2760-2024 stipulates that Disodium EDTA can be used in pickled vegetables (maximum usage 0.25 g/kg), compound seasonings (0.075 g/kg), etc.;
Beverage clarification: Removes metal ions from fruit juices to prevent turbidity and discoloration.
3. Pharmaceuticals and Biochemistry
Pharmaceutical excipients:
As an in vitro anticoagulant for injection, chelates Ca2⁺ in blood to prevent the coagulation process (e.g., in blood preservation solutions);
Used for detoxification of heavy metal poisoning (e.g., lead, mercury), promoting the excretion of metal ions from the body through chelation;
Biological experimental reagents:
Chelates metal ions in enzymatic reaction systems in molecular biology (e.g., inhibiting nuclease activity) or used as a buffer component;
Used to dissociate adherent cells in cell culture (EDTA - trypsin mixture).
4. Daily Chemicals and Cosmetics
Cosmetic additives: Chelate metal ions in water to prevent the failure of preservatives (e.g., parabens) and avoid emulsion separation or discoloration;
Detergent builders: Enhance the detergency of surfactants (especially in hard water) and reduce soap scum formation. Main Uses
