Abstract

The present invention provides low-density compositions, as well as particulates formed, at least in part, from such compositions. Preferred low-density materials include, for example, hollowspheres, low-density minerals, and low-density wood materials (e.g., sawdust). The low-density compositions of the invention can be formed as particulates, or cores, suitable for use in forming enzyme granules, e.g., marums, layered granules, prills, drum granules, agglomerated granules, or the like. Granules are disclosed having advantageous properties, e.g., low dusting, storage stable, fast enzyme-release profile, low true density, etc. The granules of the invention are especially useful, for example, in liquid detergents and cleaners, such as predominantly aqueous, liquid laundry detergents. In one embodiment, granules are provided having a true, or volumetric, density within a range of from about 0.95 to about 1.4 g/cm.sup.3. The granules can be economically produced in commercial quantities by way of a marumerization, drum granulation, fluid-bed spray-coating, pan-coating, or other suitable process.
