Abstract (en)
An alkali containing silica solution comprising 15% to 30% by weight of silica, 10% to 25% by weight of potassium or sodium oxide or mixtures thereof, 2% to 6% by weight of a compatible neutralised organic acid calcium sequestrant the SiO2/Na2O ratio of the alkali containing silica solution being in the range 1.2 to 2.0 has been found to be a suitable stabilizer for alkaline hydrogen peroxide bleaching of textiles.
