Definitions

  • the present invention relates to an aqueous sanitary cleaning com- position 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 already 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.
  • 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 nowadays 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. [0004] On the other hand, cleaning compositions merely based on sulfamic acid have some disadvantages with respect to labelling 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 which may lead to, for example, stress corrosion cracking. Another problem which is sometimes observed with cleaning compositions accord- ing 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 aesthetical 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.
  • aqueous sanitary cleaning composition which is less irritant to the skin, has an increased material compatibility, enables higher perfume stability, and is less corro- sive to metal surfaces such as steel and aluminium, but nevertheless has good lime-removing capacity and good cleaning properties.
  • Said cleaning composition of the invention comprises an sulfamic acid in an amount of up to 8 wt.%, a hydroxycarboxylic acid and water, wherein the weight ratio of the sulfamic acid to the hydroxycarboxylic acid is 80:20 to 20:80.
  • the sulfamic acid is in an alternative embodiment of the invention present in an amount of only up to 6 wt.- %, preferably in an amount of below 5 wt.-%.
  • the sulfamic acid is preferably present in a minimum amount of 1 wt.-% and more preferably in a minimum amount of 2 wt.-%.
  • the sulfamic acid to be used is favourably sulfamic acid itself but is not limited to this acid. Also N-alkyl, N-aryl, or N-allyl derivatives thereof if highly soluble in water can be used.
  • 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.
  • acids are for example lactic acid, maleic acid, citric acid, gly- colic 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 preferred acid is lactic acid.
  • Lactic acid has the further advantage that it is slightly antimicrobial. That is why lactic acid is notified as having dis- infecting 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 stated in the year 2002.
  • the advantage of using lactic acid as component in a sanitary cleaning composition therefore is that such a composition additionally has disinfecting properties and is allowed to be labelled accordingly.
  • the hydroxycarboxylic acid of the sanitary cleaning composition according to the invention is present in an amount of up to 10 wt. -%.
  • An amount of up to 6 wt. -% or even below 4 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 1 wt.-% and more preferably in a minimum amount of 2 wt.-%.
  • the weight ratio of the sulfamic acid and the hydroxycarboxylic acid in the sanitary cleaning composition according to the invention is 80:20 to 20:80 as mentioned above. However, in a preferred embodiment of the invention the ratio is below 60:40 to 40:60, and more preferred between below 60:40 and 50:50.
  • the sanitary cleaning composition comprises urea.
  • the cleaning composition according to the invention comprises urea especially in the case that also perfumes are contained in the composition. The reason therefore is that 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 0.5 to 10 wt.-%, preferably 2 to 8 wt.-%, and more preferably in an amount of 4 to 6 wt.-%.
  • composition according to the invention may comprise one ore more surfactants, preferably selected from the group consisting of non-ionic, anionic and/or amphoteric surfactants, or mixtures thereof.
  • the preferred surfactants are non-ionic surfactants. If surfactants are used they are usu- ally present in the composition in an amount of 0.1 to 10 wt.-%, preferably 0.5 to 5 wt.-%, and more preferably in an amount of 1 to 4 wt.-%.
  • Non-ionic, anionic and amphoteric surfactants which are usable in context with aqueous cleaning compositions are well-known for the person skilled in the art. 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 non-ionic, anionic and 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 anionic surfactants which comprises, for example, ethoxylates of alcohols, amines, amides and acids.
  • Preferred su rfactants are alcohol ethoxylates.
  • perfumes and dyes are used as auxiliary compounds in the sanitary cleaning composition. If one or more perfumes are used in the cleaning composition of the invention they are usually present in an amount of 0.01 to 2 wt.-%, preferably in an amount of 0.05 to 0.8 wt.-%, and most preferably in an amount of 0.1 to 0.6 wt.-%. If one or more dyes are used they are usually present in an amount of 0.0001 to 0.1 wt.-%, preferably in an amount of 0.0005 to 0.01 wt.-%, and most preferably in an amount of 0.001 to 0.005 wt.-%.
  • An auxiliary compound which may also be comprised in the cleaning composition according to the invention is one or more alcohols.
  • the alcohol can 5 be used to solve the perfume and/or other auxiliary compounds in a premix solution which is then used to formulate the cleaning composition.
  • the preferred alcohol is ethanol. If one or more alcohols are used they are usually present in an amount of 0.05 to 10 wt.-%, preferably in an amount of 0.1 to 5 wt.-%, and most preferably in an amount of 0.5 to 2 wt.-%.
  • the sanitary cleaning composition of the invention may optionally comprise additional agents like disinfecting agents, preservatives, corrosion inhibitors, complex builders, enzymes and bleaching agents.
  • the pH value of the freshly formulated cleaning composition ac- i5 cording to the invention is adjusted to be equal or above 0.8, preferably equal or above 0.9, and most preferably equal or above 1.05.
