Definition and Usage Areas of E.D.T.A

E.D.T.A Belgium, It acts as a weak organic acid. Carboxylic acids donate hydrogen ions if there is a base to accept them. In this way, they react with both organic (for example, amines) and inorganic bases. Their reaction with bases, called “neutralizations”, is accompanied by significant amounts of heat. Neutralization between an acid and a base creates water plus a salt.

Carboxylic acids with six or less carbon atoms are freely or moderately soluble in water; Those with more than six carbons are poorly soluble in water. Soluble carboxylic acid dissociates from some water to obtain hydrogen ions. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as neutralization forms a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Carboxylic acids, like other acids, react with cyanide salts to form gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with cyanide solutions to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are produced by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrites, and sulfides. E.D.T.A Belgium Carboxylic acids react with sulfides, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), especially in aqueous solution, to produce flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates produces a harmless gas (carbon dioxide) but still gives off heat. Like other organic compounds, carboxylic acids can be oxidized with strong oxidizing agents and reduced with strong reducing agents. These reactions produce heat. A wide variety of products are possible. Like other acids, carboxylic acids can initiate polymerization reactions; As with other acids, they usually catalyze (speed up) chemical reactions. Usage areas

• Because it is so good at displacing molecules in coordination complexes, EDTA can be used to prevent small amounts of unwanted metals from reacting and having harmful effects on products.
• EDTA serves to increase the resistance of the cosmetic product against airborne molecules.
• Similarly, in personal care and skin care products, EDTA binds to free metal ions and acts as a purifying agent and persister.
• It fundamentally reduces the “hardness” (or presence of metal cations) in tap water so that other ingredients in shampoo and soap can work to clean more effectively.
• EDTA is used in laundry detergents to soften the water that comes into contact with it so that other active ingredients can clean better.
• In textiles, EDTA prevents discoloration of dyed fabrics by removing colorless metal ions and also removes residues from industrial equipment (i.e. broilers) that must be used at high temperatures.
• In general, EDTA lowers the reactivity of a metal and prevents the undesirable effects that may arise from its presence. EDTA is used in salt form, most likely disodium or calcium disodium EDTA.
