<p>A detergent tablet for fabric washing is compacted from a particulate composition containing 5 to 50 % detergent active, 2 to 60 % of water-soluble inorganic phosphate builder and other ingredients including 8 to 30 % of peroxygen bleach, wherein the tablet has a density of at least 1040 gm/litre and the bleach is sodium percarbonate, sodium perborate tetrahydrate or a mixture of them. This selection of peroxygen bleach leads to a better combination of strength before use with speed of disintegration at the time of use.</p> |
