Abstract (en)

[origin: GB2307914A] A phosphate-free detergent composition suitable for use in laundry washing methods comprises from 1% to 45% by weight of the composition of a nil-phosphate builder system; a bleaching system capable of providing a hydrophobic organic peroxyacid compound having at least 7 carbon atoms; a two-component heavy metal ion sequestrant system comprising one sequestrant having a oxidizable amino linkage and a second heavy metal ion sequestrant having no such oxidizable amino linkage. Enhanced stain removal and body soil cleaning when the composition is employed in a laundry wash method.
