Abstract
The present disclosure provides methods for controlling swelling of a clay when in contact with an aqueous medium. The methods may include contacting clay with a content of an ionic liquid sufficient to modify one or more transport properties of water through the clay. In particular, in some embodiments, the present disclosure provides clay-based animal litter compositions having controlled flow and clump shape, and a related method. The animal litter can include a clay-based liquid absorbing material and at least one ionic liquid.
