Definitions

  • the present invention is in the field of dishwashing, in particular it relates to dishwashing and automatic dishwashing products, auxiliaries and methods suitable for the removal of cooked-, baked- and burnt-on soils from cookware and tableware.
  • Cooked-, baked- and burnt-on soils are amongst the most severe types of soils to remove from surfaces. Traditionally, the removal of cooked-, baked- and burnt-on soils from cookware and tableware requires soaking the soiled object prior to a mechanical action. Consequently, the automatic dishwashing process alone does not provide a satisfactory removal of cooked-, baked- and burnt-on soils.
  • US-A-5, 102,573 provides a method for treating hard surfaces soiled with cooked-on, baked-on or dried-on food residues comprising applying a pre-spotting composition to the soiled article.
  • the composition applied comprises surfactant, builder, amine and solvent.
  • WO-A-94/28108 discloses an aqueous cleaner concentrate composition, that can be diluted to form a more viscous use solution comprising an effective thickening amount of a rod micelle thickener composition, lower alkyl glycol ether solvent and hardness sequestering agent.
  • the application also describes a method of cleaning a food preparation unit having at least one substantially vertical surface having a baked food soil coating.
  • JP-A- 10,017,900 discloses an automatic dishwashing auxiliary composition comprising non- ionic low foaming surfactant, organic solvent and water. The composition delivers detergency and drying benefits.
  • JP-A-11,117,000 discloses a cleaning assistant composition for automatic dishwashing machines comprising surfactant, organic high- molecular polyelectrolyte, water-soluble solvent and water. The claimed assistant composition helps in the cleaning of stubborn dirt such as that due to oil or lipstick.
  • a method of removing cooked-, baked-, or burnt-on food soil such as grease, meat, dairy, fruit, pasta and any other food especially difficult to remove after the cooking process
  • cookware and tableware including stainless steel, glass, plastic, wood and ceramic objects.
  • the method comprises washing the cookware/tableware in an automatic dishwashing machine in the presence of an organic solvent system (comprising a single solvent compound or a mixture of solvent compounds) having a volatile organic content above 1 mm Hg of less than about 50%, preferably less than about 20% and more preferably less than about 10% by weight of the solvent system.
  • volatile organic content of the solvent system is defined as the content of organic components in the solvent system having a vapor pressure higher than the prescribed limit at 25 °C and atmospheric pressure.
  • the optimum concentration of the solvent in the wash liquor is from about 100 ppm to about 10000 ppm, preferably from about 200 to about 8000 and more preferably from about 500 to about 5000 ppm.
  • the organic solvent system is preferably used in combination with a surfactant, especially a low foaming non-ionic surfactant and a detergency builder.
  • another embodiment of the invention provides a method of removing cooked-, baked-, or burnt-on food soil from cookware and tableware comprising washing the cookware/tableware in an automatic dishwashing machine in the presence of surfactant, detergency builder and an organic solvent system wherein the surfactant has a wash liquor concentration of from about 10 to about 1000, preferably from about 100 to about 600 ppm, the detergency builder has a wash liquor concentration of about 100 to about 5000, preferably from about 1000 to about 3000 ppm and the organic solvent system has a wash liquor concentration of from about 100 to about 10000 ppm, preferably from about 200 to about 8000 ppm and more preferably from about 500 to about 5000 ppm.
  • the surfactant has a wash liquor concentration of from about 10 to about 1000, preferably from about 100 to about 600 ppm
  • the detergency builder has a wash liquor concentration of about 100 to about 5000, preferably from about 1000 to about 3000 ppm
  • the organic solvent system has
  • the pH of the wash liquor will generally be in the alkaline range, preferably at least 10.5 or more preferably at least 11.0, this pH being provided by means of an alkalinity source or sources in one or more compositions used for delivery of the solvent, surfactant and builder.
