Abstract
Official abstract text for this publication.
The present invention relates to odor-inhibiting compositions comprising water-absorbing polymer particles and metal peroxides, and to the production thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for producing a composition, comprising a mixture of water-absorbing polymer particles and at least one of zinc peroxide, magnesium peroxide, and calcium peroxide on the water-absorbing polymer particles, wherein the composition comprises from 0.001 to 5% by weight of the at least one of zinc peroxide, magnesium peroxide, and calcium peroxide, less than 10% by weight of water, and at least 90% by weight of the water-absorbing polymer particles, which comprises performing at least one of the following steps: i) mixing at least one metal peroxide, metal hyperoxide, or metal ozonide together with water-absorbing polymer particles, and/or ii) grinding at least one metal peroxide, metal hyperoxide, or metal ozonide together with water-absorbing polymers, and/or iii) spraying at least one metal peroxide, metal hyperoxide, or metal ozonide onto water-absorbing polymer particles, and iv) optionally mixing a composition obtained in i), ii) and/or iii) together with further water-absorbing polymer particles. 2. The process according to claim 1 , wherein the water-absorbing polymer particles comprise at least 50% by weight of polymerized acrylic acid and/or salts thereof. 3. The process according to claim 1 , wherein the water-absorbing polymer particles have a centrifuge retention capacity of at least 15 g/g. 4. The process according to claim 1 , wherein the composition comprises from 0.1% to 1.5% by weight, of at least one of the zinc peroxide, magnesium peroxide, and calcium peroxide. 5. A hygiene article comprising at least one composition comprising a mixture of water-absorbing polymer particles and at least one of zinc peroxide, magnesium peroxide, and calcium peroxide on the water-absorbing polymer particles, wherein the composition comprises from 0.001 to 5% by weight of the at least one of zinc peroxide, magnesium peroxide, and calcium peroxide, less than 10% by weight of water, and at least 90% by weight of the water-absorbing polymer particles.
