Patent

CA 2286087

Tablets of detergent composition are compacted to a diametral fracture stress of 8 to 60 KPa using 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.

L'invention concerne des pastilles de compositions détergentes comprimées jusqu'à obtention d'une contrainte de rupture diamétrale de 8 à 60 KPa en utilisant un moule dont au moins une des parties comporte une couche élastomérique venant en contact avec la composition. Ce procédé améliore la perméabilité de la surface de la pastille et donc la vitesse de reprise d'eau et la vitesse de dissolution/désintégration au moment de l'utilisation.
