Abstract

Dishwashing composition for the machine washing of crockery at around 40.degree. C. which contain, in addition to polymeric alkali phosphates (di-, triphosphates), water-soluble complexing zeolites of the NaA or NaX type or organic complexing agents for calcium, alkali metasilicate, sodium carbonate, sodium hydrogen carbonate, waterglass, active oxygen donors and a low-foaming nonionic surfactant from the group of alkylene oxide adducts with C.sub.12 -C.sub.18 alkanols, nonylphenol or with polypropylene glycols having a molecular weight of from 900 to 4000, (1) form about 0.1 to 5% by weight of a hydrolase enzyme (amylases, proteases, lipases) and, (2) as cleansing boosters, from about 0.1 to 10% by weight of C.sub.8 -C.sub.10 primary, straight-chain or branched-chain alkanols which may optionally be propoxylated with from 1 to 2 moles of propylene oxide.
