A detergent block of compressed granular material is provided, said block having a weight of 0.2-10 kg, being substantially free of phosphate builder material, and comprising a granulated builder material, an alkaline agent and a compressing aid. A process is also provided for preparing a block of compressed granular material being substantially free of a phosphate builder and having a weight of 0.2 to 10 kg, said process involving the steps of (i) granulating a non-phosphate builder material, with 0.1-10 % by weight based on the weight of the builder of a co-ingredient selected from polycarboxylic polymer solutions, alkali metal silicate solutions, and mixtures thereof; and (ii) compressing a particulate mixture of said granulated builder material and other components of the block, including a compressing aid, in a mould under a pressure of 3-30 kN/cm2.
La présente invention concerne un bloc de détergent constitué d'une matière granulée comprimée pesant de 0,2 à 10 kg, ne contenant pratiquement pas d'adjuvant phosphaté, et comportant une matière adjuvante granulée, un agent alcalin et un agent favorisant la compression. L'invention concerne également un procédé de préparation d'un bloc de matière granulée comprimée ne contenant pratiquement pas d'adjuvant phosphaté et pesant de 0,2 à 10 kg, ledit procédé consistant (i) à granuler une matière adjuvante ne contenant pas de phosphate, avec 0,1 à 10 % en poids, relativement au poids de l'adjuvant, d'un co-ingrédient choisi parmi des solutions polymères carboxyliques, des solutions de silicate de métal alcalin et des mélanges de ces solutions, et (ii) à comprimer un mélange particulaire de ladite matière adjuvante granulée ainsi que les autres ingrédients du bloc, y compris l'agent favorisant la compression, dans un moule, sous une pression de 3 à 30 kN/cm<2>.
