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. The core preferably is in an amount of 10-50% of the granulate and has an average particle size of between about 100 .mu.m and 1000 .mu.m. The fibers preferably have an average length of 50-2000 .mu.m and an average width of 5-50 .mu.m. The granulates are produced by sequentially introducing the core, the sustained release or protective agent, if present, and the components of the shell into a granulating device such as a drum granulator.

The detergent additive granulate is a coated co-granulate containing at least one enzyme and at least one photobleaching agent. If a detergent, a component of which is such detergent additive granulate, is used for laundering, the photobleaching agent will not tend to adhere selectively to the laundry during the initial washing process.

Detergent additive granulate and detergent

Particles containing enzyme or optical brightener in a mixture with particles containing peroxy bleach, surfactant or builder stabilized during storage by coating the former and/or the latter particles with clay, e.g. bentonite.

Stabilized particulate composition

The granulate detergent enzyme product comprises a core of a microbial enzyme containing material with an enteric coating. Due to the coating the enzymatic stability is enhanced, in the presence of other detergent components, espacially strong bleaching agents. The coating is usually carried out in a fluid bed. Also coatings with antioxidants and acid coatings enhance the enzymatic stability.

Enteric coated detergent enzymes

A protected enzyme system suitable for storage, prior to use, in a medium such as a liquid detergent which causes degradation of the unprotected enzyme, which system comprises at least one enzyme dispersed in a hydrophobic substance which does not dissolve on storage and which is liquid under the conditions of use.
