Abstract (en)
[origin: WO9217564A1] A process for removing especially starch-containing impurities from crockery in dishwashers makes it possible effectively to remove the impurities if a concentrated aqueous tenside solution is used which contains 0.08 to 2.0 % wt. N-C8? to C12? alkyl pyrrolidone, 0.005 to 0.125 Anson units of one or more proteases and/or 0.1 to 6 kilo-novo units of one or more amylases per litre of solution, buffer substances active in the pH range from 5 to 9 and conventional solvent agents and possibly conventional additives like foam suppressors, perfumes, colourants, thickening agents, preserving agents and hardness dispersants.
