Abstract (en)

[origin: DE19622131A1] New enzyme granulates are described which contain an organic disulfide compound (R-S-S-R'), particularly they contain the free amino acid cystine, optionally mixed with the amino acid cysteine. The new enzyme granulates are for use in detergent and cleanser compositions, particularly in dishwasher compositions, and they have positive properties, for example, insofar as protecting objects made of silver or coated with silver against tarnishing, for example, dishes, cutlery and other objects to be cleaned.
