Abstract
A chromogenic absorbent material and related chromogenic solution, use, process and application for an animal litter. The chromogenic absorbent material includes an absorptive material for absorbing an animal excretion; an oxidizing agent responsive to peroxidatic/pseudoperoxidatic activity in the animal excretion to provide oxidizing activity; and an inclusion complex including a host compound and a guest compound, the guest compound being a chromogenic indicator associated with the host compound and being chromogenically responsive to the oxidizing activity of the oxidizing agent. The chromogenic absorbent material may be prepared from the chromogenic solution including the oxidizing agent and the inclusion complex. The chromogenic absorbent material may be used as particles combined with animal litter for detection of peroxidatic/pseudoperoxidatic activity in the animal excretion. The chromogenic material or solution may include a buffering agent, a colour enhancer, a stabilizer or a metal-scavenger agent or a combination thereof.
