Functions:
Ethylenediaminetetraacetic acid, widely abbreviated as EDTA (for other names, see Table), is a polyamino carboxylic acid and a colourless, water-soluble solid. Its conjugate base is named ethylenediaminetetraacetate. It is widely used to dissolvelimescale. Its usefulness arises because of its role as a hexadentate ("six-toothed") ligand and chelating agent, i.e. its ability to "sequester" metal ions such as Ca2+ and Fe3+. After being bound by EDTA, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA.    

Applications:                                                                                 
Triclosan has been used since 1972, and it is present in soaps (0.10-1.00%), deodorants, toothpastes, shaving creams, mouth washes, and cleaning supplies, and is infused in an increasing number of consumer products, such as kitchen utensils, toys, bedding, socks, and trash bags.[5] Triclosan has been shown to be effective in reducing and controlling bacterial contamination on the hands and on treated products. .

EDTA-4Na is an important chelant of metal ion. It is used as additive, activator, clean water agent and metal ion masking composition for cleanse industry, polyreaction, watertreatment, color photosensitive and paper industry.
