There is provided an absorbent composition for water-based liquids, wherein dusting normally associated with handling of powdered absorbent materials is significantly reduced. The composition can be an animal litter, such as cat litter. The composition is formed by mixing a filler with a de-dusting agent and spraying an aqueous slurry of a deodorizing agent onto the mixture. The mixture is then added to a water absorbing material such as clay to uniformly mix the deodorizing agent with the water absorbing material.

This invention provides a process for the production of dry free-flowing potassium carbonate sesquihydrate. The process involves the controlled hydration of high purity anhydrous potassium carbonate. The product of the process has at least about 90 percent particle size distribution in the range between about 200-1500 microns. The invention potassium carbonate sesquihydrate has properties which adapt the product for utility as a macromineral nutrient in animal feedstocks.
