Definitions

  • carbohydrate soils such as cellulosic, monosaccharides, disaccharides, oligosaccharides, starches, gums and other complex materials, when dried, can form tough, hard to remove soils, particularly when combined with other soil components such as proteins, blood, fats, oils, minerals, and others. The removal of such soils and residues, can be a significant problem.
  • Clean out of place systems (COP) cleaning techniques are a specific cleaning regimen adapted for removing soils from exterior surfaces of a wide variety of parts, such as ceramic surfaces, metal surfaces, walls, wash tanks, soaking vessels, mop buckets, holding tanks, scrub sinks, vehicle parts washers, non-continuous batch washers and systems, ceilings, external parts of production machinery and the like.
  • Often clean out of place methods can involve a first rinse, the application of the cleaning solutions, and a second rinse with potable water followed by resumed operations.
  • the process can also include any other contacting step in which a rinse, acidic or basic functional fluid, solvent or other cleaning component such as hot water, cold water, etc. can be contacted with the equipment at any step during the process.
  • Conventional clean in place as well as clean out of place methods require high temperatures, up to 80° C. In production rooms, the elevated water temperature currently used for that kind of cleaning processes is in the range of 40° C to 60° C.
  • Conventional clean out of place techniques (COP) thus require the consumption of large amounts of energy.
  • Detergent compositions generally used in clean out of place processes, related to medical devices, hospitals, food and meat processing industry are no-foaming or low foaming liquid compositions.
  • No-foaming or low foaming detergent compositions have the drawback that the dwell time or so called "soaking time" on an upright tiled wall is short due to a good flow rate of the liquid detergent composition.
  • no-foaming or low foaming detergent compositions have the drawback that the user cannot easily track the areas that are processed or not processed due to the brief residence time of the detergent composition, and low foam stability. There is a tendency that surfaces to be cleaned are treated twice thus require the consumption of large amounts of water and detergent composition.
  • the object addressed by the present invention is to provide a long lasting foaming detergent composition that has excellent soil removal properties at lower temperatures, increased foam stability, increased dwell time and being traceable, that can be used for example in removing soil from a surface to be cleaned, preferably in a clean-out-of-place systems (COP) or in a clean-in-place system (CIP).
  • COP clean-out-of-place systems
  • CIP clean-in-place system

  • the composition of the invention is applied to the surface to be cleaned in the form of a foam.
  • the foam has compared to know foaming composition an remarkable increased dwell time and liquid absorption capacity and the foam treated areas can be easily tracked due to the visibility of the foam that avoids multiple treatment of the same area.

  • the aqueous foaming detergent composition can be applied to the surfaces to be cleaned in form of foam. Applying foam to an upright surface to be cleaned provides a long lasting contact time and the treated areas can be easily traced.
  • the aqueous foaming detergent composition allows for the use of reduced levels of chemistry, because the foaming detergent of the invention has a remarkable increased cleaning efficiency that allows the use of a lower concentrated foaming detergent composition.
  • the methods of the present invention provide for reduced energy consumption, e.g., lower cleaning temperatures, and reduced chemical consumption.
  • by weight refers to the total weight of the composition. For example, if a composition has a total weight of 100 grams and comprises 40% (by weight) of an alcohol, the composition may comprise 40 grams of alcohol.

  • C 6 -C 20 alcohols is not a solvent, but an active agent.
  • the term "surface” refers to a surface of a medical instrument, a healthcare setting, a tool, a machine, equipment, a structure, a building, or the like that is employed as part of a food processing, preparation, or storage activity.
  • healthcare settings include hospitals, doctor's offices and long term care facilities.
  • food processing surfaces include surfaces of food processing or preparation equipment, e.g., slicing, canning, or transport equipment, including flumes, of food processing wares, e.g., utensils, dishware, wash ware, and bar glasses), and of floors, walls, or fixtures of structures in which food processing occurs.
