Abstract (en)

[origin: WO9846719A1] Tablets of detergent composition are compacted using relatively movable mould parts, at least one of which bears an elastomeric layer to contact the composition. This enhances permeability at the tablet surface and hence the speed of water uptake and speed of dissolution/disintegration at the time of use. Compaction is carried out with sufficient pressure to form tablets containing from 20 to 35 % air by volume. Tablets of the invention take up water rapidly upon immersion, such that at least 65 % of the air space within the tablet is filled with water within 30 seconds.
