Enzyme-containing granulated substance and preparation process thereof

Abstract

The present invention relates to an enzyme-containing granulated substance comprising an enzyme-containing particulate substance and a coating layer which is formed on the particulate substance and comprises (a) water-insoluble or hardly water-soluble inorganic particles having an average particle diameter of 1 to 100 .mu.m, (b) water-insoluble or hardly water-soluble inorganic particles having an average particle diameter of 0.01 to 0.8 .mu.m and (c) a binder, and a preparation process thereof. The enzyme-containing granulated substance is not only high in productivity but also low in dusting characteristics and high in storage stability, and is hence useful as a formulation ingredient for detergents, in particular, bleacher-containing detergents.
