Abstract

DC60 (15/12/41) bleaching and oxidation catalyst containing active iron complexes. In the catalytic reaction With the listed pentadentate nitrogen present in the ligand, this type of iron complex can activate hydrogen peroxide or peroxy acid and have been found to have Features in Good stain removal and dye transfer inhibition, the additive is stabilized at Improved of Stacking of these irons in an alkaline water environment Especially at the concentration of peroxy compounds present. Common in detergents used to wash clothes Bleaching and oxidation catalysts containing iron complexes that accelerate the composite reaction. With the listed pentatentate nitrogen contained in the ligand, this type of iron complex can stimulate hydrogen peroxide or peroxy acid and have been found to have antiseptic properties. It removes stain well and inhibits dye transfer. Additives get the improved stability of the organic compound. Stacking of these irons in an alkaline water environment Especially at the concentration of peroxy compounds present. Common in detergents used to wash clothes
