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. An odor-inhibiting 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. 2. The composition 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 composition according to claim 1 , wherein the water-absorbing polymer particles have a centrifuge retention capacity of at least 15 g/g. 4. The composition according to claim 1 comprising from 0.1% to 1.5% by weight, of at least one of the zinc peroxide, magnesium peroxide, and calcium peroxide.
