ABSTRACT:
Automatic dishwashing compositions comprising a nonionic surface-active agent and a binary enzyme system are disclosed. The enzyme system comprises a proteolytic enzyme having a proteolytic activity of 80 to 100% of maximum activity when measured at pH 12 using the Anson hemoglobin method carried out in the presence of urea, and an amylolytic enzyme. Preferred amylolytic enzymes are those which show an amylolytic activity of more than 50% of maximum activity when measured at pH 8 by the SKB method at 37.degree. C. The composition may be made in granular, pasty, or gelled form, and may contain other components usually found in automatic dishwashing compositions. A process for washing dishes utilizing the compositions of the present invention is also disclosed.
