Abstract
La présente invention a trait à des formulations absorbantes synergiques à composantes multiples comportant au moins un polysaccharide et au moins un composant à base de polysaccharides ou de protéines gélifiantes. Ces formulations exercent un effet synergique sur la capacité à absorber de l'eau, des solutions salines et des fluides biologiques, sous pression normale ou sous une charge, ou à retenir de tels fluides, ou possèdent une combinaison de ces propriétés.
