Low dust animal litter

Abstract

Provided is a carrier material and its use in animal litter, wherein the carrier material exhibits reduced dust formation during handling. The carrier material comprises: bentonite clay; and a dust suppression agent coated on the bentonite clay, wherein the dust suppression agent is one or more alkoxylate materials of formula (I): R-O-(AO)2-H, wherein R is H, aryl (e.g., phenyl), or linear or branched C4-C24 alkyl; AO at each occurrence is independently ethyleneoxy, propyleneoxy, butyleneoxy, or random or block mixtures thereof; and z represents average number of moles of AO and ranges from 1to 80.

Description

technical field [0001] The present invention relates generally to animal litter for absorbing animal waste, and more particularly to animal litter exhibiting reduced dust formation during disposal. Background technique [0002] Animal litter compositions such as cat litter are widely used to collect urine and feces from trained or farm animals. Bentonite is a commonly used carrier-adsorbent material in animal bedding. Bentonite has several advantages over other carrier materials. For example, sodium bentonite aggregates to form clumps when wet. Thus, contaminated litter can be easily separated from uncontaminated litter. Non-swelling bentonites such as calcium bentonite can be aggregated or gelled by adding additives. [0003] Although bentonites are ideal carrier materials, due to their small particle size, they have the disadvantage of generating large amounts of dust when handled. This dust generation problem is known and various solutions have been proposed. One me...

Problems solved by technology

The hydrophobic nature of mineral oil may bind particles, thus reducing the surface area of ​​the litter and therefore reducing the effectiveness of bentonite to collect and absorb urine and faeces
