A chromogenic absorbent material for an animal litter includes an oxidizing agent responsive to peroxidatic/pseudoperoxidatic activity in an animal excretion or a first catalytic compound generating the oxidizing agent in situ. The material also includes a chromogenic indicator being chromogenically responsive to the oxidizing activity of the oxidizing agent, and an absorptive material which is porous, for absorbing the animal excretion. The absorptive material includes a water-absorbing polysaccharide providing absorptive properties to the chromogenic absorbent material; and may also include a second polysaccharide and a superabsorbent polymer. The material may be obtained in the form of particles having a low density and a high porosity, and is usable in conjunction with an animal litter for detecting various diseases in animals.

Chromogenic absorbent material for animal litter

A process for manufacturing particles of water-absorbing material is provided. The process includes providing a powder bed composed of an absorptive powder comprising a water-absorbing polysaccharide onto a surface; releasing an aqueous solution from a solution dispenser so as to contact the powder bed, thereby forming a solution-impregnated humid material; letting the solution-impregnated humid material agglomerate in substantially shear-less conditions to form an agglomerated humid material, the solution-impregnated humid material being supported by the surface; and drying the agglomerated humid material, thereby forming the particles.

Process and apparatus for manufacturing water-absorbing material and use in cat litter

A chromogenic absorbent material for detecting a detectable substance in a water-containing medium, such as animal urine, is provided. The detectable substance may be indicative of a disease or condition, and the water-containing medium may be an excretion, blood, plasma, an aqueous solution or a solid impregnated with an aqueous solution. The chromogenic absorbent material may include a trigger agent, a chromogenic indicator convertible into a chromogenically active substance in the presence of the trigger agent and the detectable substance, and an absorptive material which is porous, for absorbing the water-containing medium. The absorptive material may include a water-absorbing polysaccharide providing absorptive properties to the chromogenic absorbent material. The trigger agent, the chromogenic indicator and the detectable substance are preferably unreactive to the absorptive material.

Water-absorbing material and uses thereof

A process for manufacturing particles of water-absorbing material is provided. The process includes providing a powder bed composed of an absorptive powder comprising a water-absorbing polysaccharide onto a surface; releasing an aqueous solution from a solution dispenser so as to contact the powder bed, 5 thereby forming a solution-impregnated humid material; letting the solution-impregnated humid material agglomerate in substantially shear-less conditions to form an agglomerated humid material, the solution-impregnated humid material being supported by the surface; and drying the agglomerated humid material, thereby forming the particles.

Particle for animal litter

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.

A process for producing unsaturated and saturated free fatty acid from trap oils, trap greases, brown greases and grease trap waste as starting material. The process consist in subjecting the starting material to a pretreatment, a first purification step, a fractional step, a second purification step and eventually a hydrogenation step. Methyl esters of unsaturated and saturated free fatty acids, oleic acid and stearin is obtained from this process.

A process for producing microcrystalline cellulose. The process comprising the following steps: The process allows the application of a controlled depressurization in step f), which in turn allows to keep the natural texture of the fibers and to obtain a cellulose having a low degree of polymerization.

Process for producing low DP microcrystalline cellulose

Disclosed herein is a process where maltol is extracted from a source material containing maltol by employing an aqueous extraction process wherein reverse osmosis is utilized to concentrate an aqueous extract of maltol. The maltol in the concentrated aqueous extract is adsorbed on a bed containing an adsorbent material and then desorbed using a hydrophilic solvent and separated.
