Abstract

L'invention concerne un corps absorbant (16) comprenant une feuille de substrat (12) et un noyau absorbant (14). Le noyau absorbant (14) contient une résine absorbant l'eau, un polymère hydrosoluble non fibreux et un alcool polyhydrique. La résine absorbant l'eau est contenue dans une quantité de 40 % en masse à 95 % en masse (inclus) par rapport au noyau absorbant. Le polymère hydrosoluble non fibreux est contenu dans une quantité de 0,1 % en masse à 5 % en masse (inclus) par rapport à la résine absorbant l'eau. L'alcool polyhydrique est contenu dans une quantité de 300 % en masse à 1 500 % en masse (inclus) par rapport au polymère hydrosoluble non fibreux. Il est préférable que le polymère hydrosoluble non fibreux soit constitué d'un ou de plusieurs composés choisis parmi les polyvinylpyrrolidones, les polyvinylbutyrals et les dextrines. Il est également préférable que l'alcool polyhydrique soit constitué d'un ou de plusieurs composés choisis parmi le glycérol, le propylène glycol et les polyéthylène glycols.
