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 in 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:
Used as an anticoagulant for injection (in vitro), chelating 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: Chelates 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 the formation of soap scum. Main Uses
