Abstract: The invention provides a hydrogel, having a floating behaviour, wherein 40 to 90% of a solution and/or suspension to be thickened is thickened from the fluid surface and the rest of said solution and/or suspension to be thickened is thickened from the container bottom. Said invention also relates to a method for producing the hydrogel and the use thereof for absorbing blood and/or body fluids, in particular, in hygienic articles, or for thickening aqueous solutions and/or suspensions, in particular, for thickening medical waste.

Abstract: A novel hydrogel (I), showing floating behaviour, thickens 40-90% of a solution and/or suspension to be thickened from the fluid surface and the remainder of the solution and/or suspension from the bottom of the container. Independent claims are included for: (1) the preparation of a hydrogel (I'), by post-treating a dried hydrogel with a hydrophobic compound (II) and optionally a hydrophilic compound (III); and (2) mixtures of (I') with auxiliaries, specifically one or more of biocides, antimicrobial or antibacterial agents, perfumes or fragrances, stabilizers, dyes and/or pH indicators.

Abstract: Light-stable, water-absorbing polymer compositions contain a metal oxide UV absorber at 0.1-100 wt.% in combination with water-absorbing polymer particles (100 wt.%) and water (up to 20 wt.%). An independent claim is also included for production of the composition by mixing a water-absorbing polymer with UV absorber.
