Abstract

Bleach tablets comprising in addition to optional usual adjuvants and additives 45 to 85 % by weight coated percarbonate, 0 to 20 % by weight bleach activator calculated as TAED, 1 to 50 % by weight layered silicate and/or alkali metal silicate, 0 to 25 % by weight sodium/potassium carbonate, 0 to 25 % by weight sodium/potassium bicarbonate, 5 to 35 % by weight poly-functional carboxylic acid calculated as citric acid, 0 to 8 % by weight polyethylene glycol, 0 to 5 % by weight complex-binder, 0 to 2 % by weight paraffin oil, 0 to 5 % by weight disintegrating agent, 0 to 10 % by weight polymer and 0 to 10 % by weight enzymes. The bleach tablets are intended for use together with usual fabric detergent compositions and display a good storage stability and good tablet-technical properties, such as rate of dissolution and tablet strength, and they are very environmentally desirable.
