Abstract
A highly loaded concentrate pellet composition includes an active ingredient in a concentration of at least about 60% by weight, and a low molecular weight binder in a concentration of up to about 35% by weight. The active ingredient is evenly dispersed in the binder. The binder has a melting point that permits the composition to melt under shear in an extruder. The binder is non-metallocene and non-stearic.
