C 7000 (R) ABSTRACT A mildly alkaline enzymatic detergent cleaning composition adapted for use in automatic dishwashing machines com- prising (a) an amylolytic enzyme, (b) sodium triphosphate, (c) sodium carbonate and/or borax, (d) sodium silicate, (e) a peroxy compound bleach, (f) a stabilizing agent, and optionally but preferably (g) a proteolytic enzyme and/or (h) a low- to non-foaming nonionic surfactant and/or (i) a fatty acid having chain length of about 12- 18 carbon atoms, the amounts of components (b), (c) and (d) being so adjusted that the composition will have sufficient builder and buffering capacity to maintain a solution-pH of from 9.3 to 10.8. The composition presented in the form of a particulate product is an effective machine dishwashing composition comparable to conventional highly alkaline chlorine bleach-containing products.
