  • Clumpable animal litter containing a dust reducing agent
    Patent number: 5826543
    Abstract: A litter composition and a method for manufacturing a litter composition including a clumpable litter product coated with PTFE in order to reduce dustiness of the litter product. In one embodiment, the litter product contains a sodium bentonite clay substrate in combination with the PTFE additive. In another embodiment, the litter product contains a mixture of calcium bentonite clay and a guar gum additive in order to provide a clumpable litter product. According to one method, a water dispersion of a PTFE resin is sprayed onto the mixture clay product while the product is falling through the air to form fibers which attract and trap dust particles emitted from the clay mixture without causing premature clumping of the mixture.
