  • Patent number: 9084409
    Abstract: A clump-forming hygiene granulate has individual granules, each granule having: at least one inner carrier grain of a porous, mineral, non-swelling carrier material; an intermediate layer mantling the carrier grain or grains including a mixture containing at least one powder of a non-swelling, mineral, porous material, and a gel matrix composed at least of starch that swells in cold water, and a hydrocolloid different from starch, which swells in cold water; bentonite powder or superabsorber meal disposed between the carrier grain or grains and the intermediate layer; an outer mantle layer sheathing the intermediate layer, having a mantle layer surface including a mixture containing at least a powder of a non-swelling, mineral, porous material, and bentonite powder; hydrocolloid gel that swells in cold water, disposed between outer mantle layer and intermediate layer; and hydrocolloid grains of a hydrocolloid that swells in cold water, distributed on the mantle layer surface.
