Claim Text:
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.
