Abstract
Low-density enzyme-carrying granules are low dusting and/or storage-stable, and especially suitable for use in liquid detergents and cleaners, such as non-aqueous liquid laundry detergents. Preferred granules of the invention include a relatively high content of one or more low-density fillers, such as perlite or starch, to provide a desired product density. In one embodiment, the granules have a true density within a range of from about 1 to about 1.4 g/cm . The granules can be economically produced in commercial quantities using fluidized bed technology.
