Patent

CA 2318065

Detergent tablets for use in fabric washing are made by mixing: (i) particles which contain non-soap organic surfactant and other materials, especially detergency builder, with (ii) material which is other than soap or organic surfactant and which has a solubility in water of at least 10gm/litre at 20 ~C, followed by compacting the mixture into a tablet or a region of a tablet using an applied pressure in a range from 3.0 to 35 MPa. Such a pressure, used with the specified mixture, leads to tablets with good strength which also disintegrates with satisfactory speed.

L'invention porte sur des pastilles de détergent servant au lavage des tissus obtenues en mélangeant: (i) des particules de tensio-actif organique non savonneux et d'autres matériaux en particulier des adjuvants de détergence, avec (ii) un matériau autre qu'un tensio-actif savonneux ou organique dont la solubilité dans l'eau est d'au moins 10 gm/l à 20 ·C, puis en comprimant le mélange pour en faire des pastilles sous une pression comprise entre 3 et 35 MPa. L'association desdites pressions et dudit mélange donne des pastilles d'une bonne résistance, se désagrégeant à une vitesse satisfaisante.
