Abstract
The present invention relates to odor-inhibiting compositions comprising water-absorbing polymer particles and metal peroxides, and to the production thereof.
Claims5
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.
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.
