Abstract: The present invention relates to a multifunctional pellet aid including one or more binders, wherein at least one binder is an acrylic based polymer having a Tg ranging from −20° C. to +95° C., one or more inorganic solids and one or more organic solids; the particle size of the pellet aid ranging from 100 &mgr;m to 3000 &mgr;m. Adding 0.25 to 10% by weight of the multifunctional pellet aid, based on the total weight of the pellet, to a plurality of ingredients and compacting the pellet aid and ingredients to form a pellet, affords a pellet having improved mechanical strength as a solid and rapidly disintegrating upon contact with an aqueous system.
