Sequestering agent are employed in a number of applications such as builders in detergent formation to eliminate interfering effects caused by dissolved metal salts, particularly calcium or magnesium salts. Sequestering agents are also employed in other applications requiring control of metal ion content in aqueous solution such as waste water treatment, potable water conditions, micro-nutrient solubilization, gas conditioning, photographic development processing catalysis of chemical processes, finishing and conditioning of textile, etc.
The present invention relates to a novel composition of matter having utility in the sequestering or complexing of metal ions particularly calcium and / or magnesium ions. More particularly, the present invention is unique combination of water – soluble aminopolyacetate demonstrating improved chelating properties
- Prevention of pinhole formation due to catalytic oxidation caused by iron during bleaching (chelates iron / heavy metals).
- During dyeing, it prevents spots, shade change and unevenness by chelating heavy metals and dispersing impurities.
- Improved rinsing due to the scale inhibition (effective at low concentration such as its presence in rinse bath).
- During fabric preparation sequester also provides iron chelating to prevents fabric / yarn damage and provides additional stabilizing effect on the hydrogen peroxide.
