Definitions

  • the present invention relates to a new cleaning agent, in particular for use in industrial areas.
  • Cleaners are mostly surfactant-containing formulations with a wide range of uses and therefore very different compositions.
  • cleaners for hard surfaces should show an optimal application profile both in the concentrated state and in dilute aqueous solutions in conjunction with mechanical energy.
  • Cold cleaners perform without increasing the temperature.
  • the main determining factors for the cleaning action are surfactants and / or alkali carriers, alternative acids, and if appropriate also solvents such as glycol ethers and lower alcohols.
  • Household cleaners can be formulated as universal cleaners or as special cleaners for ceramics, tiles, windows, plastics, (carpeted) floors, hobs, ovens, microwave ovens, as sanitary cleaners or toilet cleaners.
  • Pipe cleaners are alkaline and consist, for example, of solid sodium hydroxide and aluminum powder.
  • sanitary cleaners mainly contain germ-reducing agents, although the sodium hypochlorite previously used is partly replaced by hydrogen peroxide or other peroxygen compounds.
  • the specialty cleaners in the do-it-yourself area include automotive, car, window, rim, engine and paint application cleaner.
  • Technical cleaners are mainly used in the beverage, food, chemical, cosmetic and pharmaceutical industries, but also in the metal industry for metal degreasing.
  • the product group also includes cleaners for car washes, tank truck and aircraft cleaners.
  • these cleaners must be formulated with low-foam surfactants, for which special non-ionic surfactants such as ethylene oxide-propylene oxide block copolymers and so-called end-capped alkyl ethoxylates are suitable.
  • Alkoxyalkylacetate one or more alkanesulfonates, one or more aryl polyglycol ethers and water.
  • the cleaning agent according to the invention has a very good cleaning effect.
  • alkoxyalkyl acetate encompasses compounds of the formula (I)
  • R 2 for alkyl
  • n stands for an integer, in particular from 1 to 50.
  • R 1 preferably represents C r C 6 alkyl
  • R 2 preferably represents C1 -C 4 alkyl
  • n is preferably an integer from 1 to 5.
  • R 1 particularly preferably represents C 1 -C 4 -alkyl
  • R 2 particularly preferably represents C j -C 3 alkyl
  • n particularly preferably represents an integer from 1 to 3,
  • n very particularly preferably stands for 2.
  • Alkyl glycol esters may be mentioned as examples.
  • Butyl diglycol esters are preferably used, particularly preferably butoxyethoxyethyl acetate.
  • alkanesulfonate encompasses compounds of the formula (II)
  • n represents an integer, preferably from 1 to 30, particularly preferably from 3 to 15 and very particularly preferably for 13 and
  • X stands for sodium or potassium.
  • Examples include sulfonates and alkanesulfonates.
  • Na alkanesulfonates are preferred, particularly preferably Na alkanesulfonate with a medium
  • aryl polyglycol ether encompasses compounds of the formula (III)
  • p represents an integer, preferably from 10 to 20, particularly preferably from 12 to 18 and very particularly preferably from 14 to 16.
  • Aryl polyglycol ethers are preferably used, particularly preferably aryl polyglycol ethers with about 16 ethoxy units (EO).
  • water includes tap water, but also demineralized water.
  • composition of the constituents mentioned for the cleaner can be varied. If the sum of the components mentioned is considered to be 100% by weight (although these do not necessarily represent the entire cleaning agent), the individual components are present in the following amounts:
  • the present invention further relates to a method for producing the cleaner according to the invention, which is characterized in that the constituents of the cleaner are intimately mixed with one another.
  • the present invention further relates to the use of the cleaner according to the invention for cleaning objects.
  • cleaning includes the removal of unwanted deposits, especially dirt from objects. Especially in industrial
  • the items to be cleaned include, for example, tanks, grinders and
  • the cleaner can be used particularly advantageously for metal degreasing, for example in the metal industry.
  • the cleaner according to the invention is free from acids, alkalis and organic solvents.
  • the good cleaning effect is achieved without the addition of aggressive or abrasive materials.
  • the cleaner is therefore well compatible with most materials, such as high-alloy steels (stainless steel), steel, glass, ceramics and some plastics, such as polycarbonates, HD-PE and fluorinated polyolefms.
  • the cleaner according to the invention can additionally contain further additives.
  • corrosion inhibitors e.g. imidazoles and triazole
  • Viscosity index improvers e.g. hydrogenated copolymers and methacrylates
  • germ-reducing e.g. phenol derivatives
  • disinfectant e.g. FN-releasing additives
  • the cleaner can also contain perfume oils.
  • the cleaner can continue to use so-called defoamers, for example
  • the cleaner according to the invention shows its good effect even at room temperature.
  • it can be used in a wide temperature range, generally between 0 ° C and 50 ° C, preferably between 10 ° C and 30 ° C.
  • Test conditions The contaminated surface was wetted with the cleaning solution for 20 minutes at room temperature. Finally, an attempt was made to clean the surface with a gentle water jet.
  • Test conditions The contaminated surface was wetted with the cleaning solution for 20 minutes at room temperature. Finally, an attempt was made to clean the surface with a gentle water jet.
