Abstract

Composant ou composition de détergents granuliformes à écoulement libre, d'une masse volumique non tassée d'au moins 650 g/l et dont le poids est composé (i) pour au moins 35 % d'un surfacteur anionique, (ii) pour 0,5 % à 30 % d'un agent chélatant et (iii) pour 0,5 % à 35 % d'un polymère ou copolymère, le rapport de poids entre l'agent chélatant et celui du polymère/copolymère se situant entre 1:100 et 1:1. On décrit également un procédé de production de ce composant ou de cette composition de détergent granuliforme. Ce procédé se caractérise en ce que l'on additionne des solutions aqueuses d'un agent chélatant et d'un polymère ou copolymère à une pâte hautement tensioactive.
