APPLICATIONS

Phosphonates derived from phosphorous (phosphonic) acid are employed in the applications of scale Inhibition, sequestration, dispersion and corrosion inhibition in addition to the main applications of agricultural chemicals such as fertilizers, pesticides, and soil conditioners. Phosphonates offer a wide range of sequestrants to control metal ions in aqueous systems. By forming stable water soluble complexes with multivalent metal ions, phosphonates prevent undesired interaction by blocking normal reactivity of metal ions. This ability contributes to function as threshold industrial water treatment and metal treatment processes (antiscalants, corrosion inhibitors, chelants, sludge conditioners, pulp bleachings, deflocculants, dispersants, metal cleaners, electroplating and crystal growth modifiers). Phosphonates are also used in manufacturing detergents, cosmetics and personal care products for special functions such as low levels iron control, stain removal, bleach stabilization, peroxide stabilization and anti-encrustation. Phosphonates existing in various compounds as acids or salts are marketed in the form of concentrated solutions.
