摘要:
Composite particles comprise a bleach catalyst plus one or more detersive enzymes. The particles are especially useful in automatic dishwashing compositions. Thus, a cobalt (III) or manganese (III) bleach catalyst is combined with protease or amylase enzymes and a carrier. The resulting particles are used in combination with perborate or percarbonate bleach to clean dishware in an automatic machine.
