Abstract
Clumping cellulosic animal litter comprising a cellulosic substrate coated with a first coating of a dual adhesive and surface active agent, and a second coating of guar gum, and the method of making such particles.
Claims21
A clumping cellulosic animal litter comprising:
- a plurality of cellulosic particles having an outer coating of guar gum, and an inner coating of a dual adhesive and surface agent at a solids level sufficient to bind the guar coating, in which the dual adhesive and surface active agent is a polyacrylate with an average molecular weight of about 1000 to 5000.
A clumping cellulosic animal litter comprising:
- a plurality of cellulosic particles having an outer coating of guar gum, and an inner coating of a dual adhesive and surface active agent at a solids level sufficient to bind the guar coating in which the dual adhesive and surface active agent is an aqueous sodium polyacrylate solution with a solids content of 43.0-45.0, a pH of 7.00-8.00, and a viscosity of 100-500 cps.
A clumping cellulosic animal litter comprising:
- a plurality of cellulosic particles having an outer coating of guar gum, and an inner coating of a dual adhesive and surface active agent, the inner coating being present at a level of from about 1% to 5% by weight, based on the weight of the granules, of a 43%-45% by weight solids solutions.
