Abstract: front page image
(EN)A method of producing a free flowing, high active, particulate anionic detergent comprising the step of adsorbing an anionic surfactant acid onto a powdered or granular material such as a phosphate, carbonate, bicarbonate or silicate so as to form an agglomerate. No water is added during the agglomeration stage. The agglomerate may subsequently be coated with a silicate and/or an alkaline salt preferably in a fluidised bed.
(FR)Un procédé de production d'un détergent anionique particulaire hautement actif, coulant, comprend l'étape d'adsorption d'un acide tensio-actif anionique sur une matière en poudre ou granulaire telle qu'un phosphate, carbonate, bicarbonate ou silicate de manière à former un agglomérat. On n'ajoute pas d'eau pendant la phase d'agglomération. On peut ensuite recouvrir l'agglomérat d'un silicate et/ou d'un sel alcalin de préférence dans un lit fluidifié.
