Definitions

  • the present invention relates to an aqueous sanitary cleaning composition having biocidal activity and to the use of said cleaning composition for cleaning of, disinfecting of, and/or lime removal from surfaces, especially from surfaces in bathrooms, kitchens and the like.
  • Aqueous cleaning compositions for the removal of dirt and lime in sanitary or kitchen areas are well-known. These compositions normally are based on inorganic and/or organic acids as well as surfactants. As additional agents these compositions often further comprise colouring agents, perfumes, viscosity control agents, disinfecting and bleaching agents, preservatives, and further auxiliary substances.
  • the cleaning compositions For the removal of persistent lime scale it is required that the cleaning compositions have a high acidity. Since strong inorganic acids such as hydrochloric acid and sulphuric acid lead to corrosion of metallic surfaces, material incompatibility and cause environmental pollution, cleaning compositions are widely used which are based on sulfamic acid. Sulfamic-acid-based cleaning compositions have a high scale-removing capability. Additional advantages of these cleaning compositions are that they can be used safely and that they are eco-friendly.
  • Cleaning compositions merely based on sulfamic acid have some disadvantages with respect to biocide regulations, material compatibility, perfume stability, and oxidation problems.
  • Sulfamic acid has some drawbacks with respect to its oxidative properties. Sulfamic acid causes corrosion when it comes into contact with metal surfaces. In contact with plastic surfaces it causes an accelerated aging of the plastic materials that may lead to, for example, stress corrosion cracking.
  • Another problem that is sometimes observed with cleaning compositions according to the state of the art is that the plastic bottles in which the compositions are filled begin to shrink after a certain storage time. This is not acceptable for safety and aesthetics reasons. Therefore, it is also desirable to provide a sanitary cleaning composition being less corrosive to metal surfaces and more compatible to various other materials such as plastics.
  • these cleaning compositions have biocidal activity.
  • biocidal it is meant that proliferation of microorganisms can be controlled by employing the cleaning composition.
  • Microorganisms for which sanitary compositions are useful to limit proliferation include, but are not limited to, Gram positive bacteria, Gram negative bacteria, yeasts, fungi, and algae. Certain of these microorganisms, when uncontrolled, can grow to dangerous levels resulting in food contamination or may directly infect humans. According to European biocide directives and European standards for proofed chemical disinfectants and antiseptics used in food, industrial, domestic, and institutional areas, disinfectant products sold in Europe must pass the following standards.
  • an aqueous sanitary cleaning composition having biocidal activity which has an increased material compatibility, enables higher perfume stability, and is less corrosive to metal surfaces such as steel and aluminium, but nevertheless has good lime- removing capacity and good cleaning properties.
  • an aqueous sanitary cleaning composition comprising benzalkonium chloride in an amount of up to about 5 wt.%, a hydroxycarboxylic acid in an amount up to about 10 wt.% and water, wherein the weight ratio of the benzalkonium chloride to the hydroxycarboxylic acid is about 1 :5 up to about 1: 1.
  • the combination of benzalkonium chloride with the presence of the hydroxycarboxylic acid gives the cleaning composition of the invention good biocidal activity along with good lime-removal properties as well as a good material compatibility with respect to plastic and metallic materials.
  • the perfume stability of such a composition is better when compared with cleaning compositions of the state of the art based solely on sulfamic acid.
  • an additional acid may be added to the invention.
  • Sulfonic or sulfamic acid is included in an alternative embodiment of the present invention.
  • Sulfonic or sulfamic acid is present in an amount of only up to about 6 wt.%, preferably in an amount of up to about 5 wt.% or below.
  • sulfamic acid is preferably present in a minimum amount of up to about 1 wt.% and more preferably in a minimum amount of up to about 2 wt.%.
  • the sulfamic acid to be used is favourably sulfamic acid itself but is not limited to this acid. Also, for example, N-alkyl, N-aryl, or N- allyl derivatives thereof, if highly soluble in water, can be used.
  • Weight percent, percent by weight, % by weight, wt.%, and the like are synonyms that refer to the concentration of a substance as the weight of that substance divided by the weight of the composition and multiplied by 100.
  • surfactant or "surface active agent” refers to an organic chemical that when added to a liquid changes the properties of that liquid at a surface.
  • Hydrocarboxylic acids are defined as organic acids having at least one hydroxyl group and at least one carboxyl group in the molecule.
  • a wide range of hydrocarboxylic acids can be used in the cleaning compositions according to the invention. These acids include for example lactic acid, maleic acid, citric acid, glycolic acid, tartaric acid, hydracylic acid, ⁇ -hydroxybutyric acid, glyceric acid, tartronic acid, salicylic acid, m-hydroxybenzoic acid, p-hydroxybenzoic acid, gallic acid, mandelic acid, and tropic acid or mixtures thereof.
  • the selected hydrocarboxylic acid is lactic acid.
  • Lactic acid provides the advantage that it is slightly antimicrobial. That is why lactic acid is notified as having disinfecting properties whereas, for example, sulfamic acid is not notified accordingly. Notification procedures follow European biocide regulations. In Germany they are integrated in the chemical regulations started in the year 2002. The advantage of using lactic acid as a component in a sanitary cleaning composition therefore is that such a composition additionally has disinfecting properties and may be labelled accordingly.
  • the hydroxycarboxylic acid of the sanitary cleaning composition according to the invention is present in an amount of up to about 12 wt.%.
  • An amount of up to 10 wt.% or even above about 0.5 wt.% is also sufficient with respect to the aimed properties of the cleaning composition according to the invention.
  • the hydroxycarboxylic acid is preferably present in a minimum amount of about 1 wt.% and more preferably in a minimum amount of 2 wt.%.
  • the amount of hydroxycarboxylic acid will vary according to the other components of the composition. For example, if the amount of benzalkonium chloride is raised, the amount of lactic acid may be lowered while still having effective biocidal activity and limescale removal properties.
  • Benzalkonium chloride (alkyl dimethyl benzyl ammonium chloride) is a mixture of alkylbenzyl dimethylammonium chlorides of various alkyl chain lengths.
  • the sanitary cleaning composition optionally comprises urea.
  • the cleaning composition according to the invention comprises urea especially in the case that perfumes are also contained in the composition.
  • Urea increases the solubility and stability of the perfumes in the aqueous cleaning composition. If urea is used it is present in an amount of about 0.25 to about 10 wt.%, preferably about 0.5 to about 8 wt.%, and more preferably in an amount of about 1 to about 6 wt.%.
  • composition according to the invention may comprise one or more surfactants in addition to the benzalkonium chloride that is a cationic surfactant, preferably selected from the group consisting of cationic, non-ionic, and/or amphoteric surfactants, or mixtures thereof.
  • a cationic surfactant preferably selected from the group consisting of cationic, non-ionic, and/or amphoteric surfactants, or mixtures thereof.
  • the preferred surfactants are non-ionic surfactants. If additional surfactants are used they are usually present in the composition in an amount of about 0.1 to about 10 wt.%, preferably about 0.5 to about 5 wt.%, and more preferably in an amount of about 1 to about 4 wt.%.
  • Non-ionic, cationic, and amphoteric surfactants useful in the context of aqueous cleaning compositions are well-known to the skilled artisan. All members of these known surfactants can be used in the cleaning compositions according to the present invention as long as they are compatible with the other compounds used in these compositions. Furthermore, it is within the routine work of a person skilled in the art to choose an appropriate surfactant from the groups of cationic, non-ionic, or amphoteric surfactants or a mixture of more than one such surfactants.
  • the surfactant or the mixture of surfactants is preferably selected from the group of non-ionic and/or cationic surfactants that comprises, for example, ethoxylates of alcohols, amines, amides and acids.
  • Preferred surfactants are non-ionic surfactants such as alcohol ethoxylates.
  • perfumes and dyes are used in the cleaning composition of the invention. If one or more perfumes are used in the cleaning composition of the invention they are usually present in an amount of about 0.01 to about 2 wt.%, preferably in an amount of about 0.05 to about 0.8 wt.%, and most preferably in an amount of about 0.1 to about 0.6 wt.%.

  • the alcohol can be used to solve the perfume and/or other auxiliary compounds in a premix solution that is then used to formulate the cleaning composition.
  • a preferred alcohol is ethanol. If one or more alcohols are used they are usually present in an amount of about 0.05 to about 10 wt.%, preferably in an amount of about 0.1 to about 5 wt.%, and most preferably in an amount of about 0.5 to about 2 wt.%.
