Abstract: An enzyme-containing granulate is prepared containing a core and a shell wherein the core and/or shell contain an enzyme and the shell contains artificial or cellulose fibers in an amount of 1.5-40%. The core may also contain the fibers in an amount of 1.5-40%. In a preferred embodiment, the core contains a primary enzyme, the fibers, a coating of a sustained release agent, and the shell contains a secondary enzyme and the fibers. The sustained release coating causes the primary enzyme to be released more slowly than the secondary enzyme in a washing solution. In another embodiment, the core contains a primary detergent additive, a coating of a protective agent, and the shell contains a secondary detergent additive and the fibers. The protective coating separates the primary and secondary detergent additives so they do not harm each other during storage. Preferably, the core and shell also contain a binder, a filler and a granulating agent.
