  • Patent number: 6204236
    Abstract: 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 us in detergent and cleanser compositions, particularly in dishwasher compositions, and they have properties. For example, insofar as protecting objects made of silver against tarnishing, for example, dishes, cutlery, and other objects to be cleaned.
