Definitions

  • the present invention is in the field of machine dishwashing compositions. More particularly, it relates to machine dishwashing compositions comprising carbohydrate oxidase enzymes and a surfactant system. The invention also relates to a method of washing kitchenware in a machine dishwasher with a machine dishwashing composition comprising carbohydrate oxidase enzymes and a process for making said composition.
  • Machine dishwashing compositions comprising bleaching enzymes have been described in the prior art.
  • W01 999/002640 discloses cleaning compositions comprising oxidoreductase (non haem haloperoxidase) with an a/b-hydrolase fold and a catalytic triad consisting of the amino acid residues serine, histidine and aspartic acid.
  • Example 19 discloses a dishwasher composition comprising 0.002 wt.% haloperoxidase, 1.2 wt.% non-ionic surfactant, pH 8.
  • Known enzyme dishwasher compositions suffer from poor stain removing power, particularly in the absence of percarbonate and/or perborate.
  • Notorious hard to remove stains include tea stains, which require substantial bleaching power to remove.
  • dishwasher compositions that are capable of being free of bleach precursors (e.g. percarbonate and/or perborate) and more preferably have reduced amounts of, preferably being free of, bleach activators and/or have reduced amounts of, preferably being free of, metal bleach catalysts yet provide (tea)-stain removing power.

  • a machine dish wash composition according to the invention is capable of effectively removing tea stains without the presence of bleach precursor, bleach activator and bleach catalyst at high temperatures. This is the more surprising since at such high temperature (and alkaline) conditions one may not expect the enzyme system to be able to effectively generate sufficient H2O2.
  • Typical optimal enzyme conditions are at low temperatures and or neutral to slightly acidic pH levels.
  • the optimal conditions for the used enzyme in the examples were a temperature of 35-40 degrees Celsius and a pH of 5.2. Yet in conditions of a pH of 10.5 with a temperature of 80 degrees Celsius it effectively generated H2O2 from the available glucose and provide excellent tea-stain removal.
  • a machine dish wash composition according to the invention is capable of effectively removing tea stain without the presence of bleach precursor and/or bleach activator at low-medium temperatures while using relatively small amounts of active enzyme and bleach catalyst, in particular a Manganese based catalyst.
  • the ability to employ relatively small amounts of active enzyme to provide good tea-stain removal is highly beneficial from a stability point of view, costs point of view as well as from a product stability point.
  • the invention also relates to a unit dose comprising a composition defined herein, wherein the unit dose is a gel, powder, liquid or combination thereof.
  • the invention relates to a method of cleaning kitchenware comprising the steps of contacting the composition a defined herein with kitchenware in the presence of water, preferably at a temperature in the range of 30 to 90 °C.
