Abstract: The present invention relates to an absorbent or a superabsorbent nanocomposite material comprising a polysaccharide and a phyllosilicate. The polysaccharide component can be a biodegradable polysaccharide that is a self-entangled glass-like polysaccharide or a crosslinked polysaccharide. The phyllosilicate component can be an exfoliation or a semi-exfoliation clay.

Abstract: The present invention relates to discrete particulate composite additives for superabsorbent polymers and includes a method of making same. The discrete particulate composite additives generally comprise a polysaccharide and an inert inorganic component. Advantageously, these discrete particulate composite additives functionally improve superabsorbent performance. They are suitable for a number of applications, including the use and manufacture of hygiene products.

Abstract: A particulate absorbent, for the absorption of liquids, comprising particles selected from the group consisting of particles of glass-like polysaccharides and of particles of glass-like polysaccharides occluding, in their internal structure, at least one surfactant, said particles: having a size of up to 620 &mgr;m; being at least 70% of a glass-like type structure; and being: 30 to 45% of a size comprised between 620 and 420 &mgr;m; 35 to 55% of a size comprised between 420 and 210 &mgr;m; and 5 to 25% of a size up to 210 &mgr;m. These particulate absorbent is non-hygroscopic, hypoallergenic and biodegradable and useful particularly in biodegradable diapers.
