This invention provides compositions comprising particulate water-soluble or water-swellable polymer at least partially agglomerated by treatment with at least one polyol, wherein the polyol is present at a level greater than about 10 wt.% based on the total weight of the composition. The particulate water- soluble or water-swellable polymer which has been at least partially agglomerated by treatment with polyol hydrates in water-containing solvents substantially faster than untreated water-soluble or water-swellable polymer, without formation of polymer lumps. The invention further provides an improved process for preparing a toothpaste composition comprising at least one dry, water-soluble or water-swellable polymer, the improvement comprising substituting for the dry, water-soluble or water-swellable polymer, particulate water-soluble or water-swellable polymer which has been at least partially agglomerated by treatment with polyol.

L'invention concerne des compositions en particules de polymère hydrosoluble ou gonflant au contact de l'eau, au moins partiellement agglomérés par traitement avec au moins un polyol, lequel représente un poids supérieur à 10 % environ par rapport au poids total de la composition. Ce type de polymère particulaire hydrosoluble ou gonflant au contact de l'eau, au moins partiellement aggloméré par traitement avec un polyol, s'hydrate sensiblement plus vite dans les solvants à base d'eau que le même type de polymère non traité, et sans formation de blocs de polymère. L'invention concerne également un procédé amélioré pour fabriquer une composition de pâte dentifrice comprenant au moins un polymère sec, hydrosoluble ou gonflant au contact de l'eau. Ledit procédé est amélioré en ce qu'il consiste à substituer à ce polymère sec un polymère particulaire hydrosoluble ou gonflant au contact de l'eau, au moins partiellement aggloméré par traitement au polyol.
