Definitions

  • the present invention relates in general to an improved cleaner for hard surface cleaning applications, including kitchens, bathrooms, tubs and tiles, amongst others, and more particularly to a hard surface cleaning composition having improved cleaning and descaling properties.
  • Hard surface cleaning compositions have been known and used in a variety of applications, including bathrooms, kitchens and other areas, particularly for toilets, showers, bathtubs, sinks, tiles, countertops, walls, floors and the like. Often times, hard surfaces accumulate both soap scum stains, which are typically residues of various types of soaps used in a household, as well as hard water stains, which are typically the result of the deposition of calcium, lime or various salts on hard surfaces over the course of time and use of various household surfaces.
  • Cleaning solutions for these household surfaces have been formulated to address both the removal of soap scum stains, as well as the descaling of hard water stains.
  • many of these cleaning solutions have employed a combination of components, in a number of instances including strong inorganic acids, organic acids or a combination of both, a surfactant or wetting agent, a solvent and a diluent to address one or both of these types of stains and/or build-ups.
  • the acid component is typically selected to address descaling of hard water stains
  • the surfactant component is typically a detergent selected to attack soap scum.
  • other additives have also been used in combination with cleaning formulations to either enhance performance or make a particular formulation more desirable from a visual or odor perspective, such as stabilizing agents, colorants and fragrances, amongst others.
  • WO 2012/065093 discloses a cleaning solution, which comprises a first organic acid comprising a carboxylic acid selected from the group consisting of lactic acid, glycolic acid, formic acid, citric acid and acetic acid; a second organic acid comprising a carboxylic acid different from the first organic acid and selected from the group consisting of gluconic acid, glycolic acid, formic acid, citric acid and acetic acid; a surfactant selected from the group consisting of amine oxides; and a solvent selected from the group consisting of ether alcohols.
  • WO 2012/065093 generally mentions that the compositions thereof have a pH of 2.0 or greater, initially to comply with the U.S. DfE's current standards. However, beyond that initial desire, WO 2012/065093 fails to disclose any specific formulations having a pH greater than 2.4, and certainly is completely silent on a pH ranging from greater than 2.4 to 3.25.
  • the present invention is directed to a hard surface cleaning solution, which comprises a first organic acid comprising a carboxylic acid selected from the group consisting of lactic acid, glycolic acid, formic acid, citric acid and acetic acid; a second organic acid comprising a carboxylic acid different from the first organic acid and selected from the group consisting of gluconic acid, glycolic acid, formic acid, citric acid and acetic acid; a surfactant selected from the group consisting of amine oxides; a solvent selected from the group consisting of ether alcohols; and a diluent; 10 and wherein the solution has a pH level ranging from greater than 2.4 to 3.25; and wherein the surfactant does not contain salt in an amount sufficient to materially affect the pH of the hard surface cleaning solution.
  • a hard surface cleaning solution which comprises a first organic acid comprising a carboxylic acid selected from the group consisting of lactic acid, glycolic acid, formic acid, citric acid and acetic acid; a second organic acid compris

  • the solvent may comprise 0.5 wt.% to 3.0 wt.% of the active cleaning composition.
  • the solvent comprises 1.4 wt.% of the active cleaning composition.
  • the solution may have a pH level of from greater than 2.4 to 3.25, after being aged for a minimum of six months.
  • the solution descales marble test tiles in the range of 1.326% to 2.995%.
  • the solution has a pH ranging from greater than 2.4 to 3.06, as measured before aging, optionally wherein the solution comprises:
  • the solution does not contain bleach in an amount sufficient to materially affect the pH level of the solution, or in an amount to cause the formation of noxious gases.
  • the present invention is directed to a liquid cleaning solution which is particularly suited for removing soap scum, hard water stains, lime scale and the like from various hard surfaces such as tubs, tiles, showers, sinks and other areas which are exposed to water and soap.
  • the present invention includes a cleaning solution which is a more vigorous solution more suitable for removing hard water stains, lime scale and rust.
  • a cleaning solution according to the present invention includes a first chelating agent, a second chelating agent, a surfactant or wetting agent, a solvent and a diluent.
  • the first and second chelating agents are both organic acids, namely first and second organic acids, and more specifically are selected from the class of carboxylic acids.
  • Organic acids tend to be less corrosive, more environmentally friendly and break down more rapidly than counterpart inorganic acids which are often used in cleaning solutions.
  • the first organic acid is preferably present in an amount of 12.0 wt.% to 18.0 wt.%, where the percentage is based upon the active component in the overall cleaning solution composition, which convention will be used throughout this specification unless indicated otherwise.
  • the first organic acid is selected from the group of carboxylic acids selected from the group consisting of lactic acid, glycolic acid, formic acid, citric acid and acetic acid. Most preferably, the first organic acid comprises lactic acid in an amount of 16.2 wt.% of the solution, which is sold under the Purac 88 brand and can be purchased from Purac America, headquartered in Lincolnshire, Illinois.
  • the second organic acid preferably present in an amount of 2.5 wt.% to 3.75 wt% active in the formula, is also a carboxylic acid selected from the group consisting of gluconic acid, glycolic acid, formic acid, citric acid and acetic acid.

  • first and second organic acids tends to be less corrosive than other combinations of organic and/or inorganic acids typically present in commercial hard surface cleaning solutions, which often include citric acid.
  • the gluconic acid is milder on the skin than many alternative acid cleaning components.
  • lactic acid and gluconic acid tend to have a more favorable odor than other substitute acids such as formic acid and better cleaning and descaling properties than alternative acids such as glycolic acid.
  • the most preferred lactic and gluconic acids are also chosen as they have been found to have a synergistic compatibility with each other as well as with the surfactant system and solvent of the present invention. It is important that the organic acids are not reactive with and adverse to the surfactant system which can cause a drop-off in effectiveness and functionality of the cleaning solution.
  • the surfactant is an amine oxide, preferably lauramine oxide ("LO"), which is also known as lauryldimethylamine oxide, dodecyldimethylamine oxide or dimethyldodecylamine-N-oxide.

  • Other alternative sources of lauramine oxide are Macat AO -12 (from Mason Chemicals) and Ammonyx LO (from Stepan Chemical).
  • Commercially available LO is notable because it does not contain any salt (NaCI) as a result of the production process nor does the chemical itself contain a sodium component.
  • surfactants that contain salt (NaCI), or sodium (Na), either as an element of the fundamental surfactant molecules, or as a production byproduct can have a tendency to suppress the pH of the resulting cleaning solution, even when the pH of the surfactant constituent itself is fairly high (>9 or 10).
  • surfactants that clearly lacked a sodium component either as an element in the fundamental surfactant molecule, or as part of a production byproduct, such as glycosides, which also had a high initial pH, likewise failed to elevate the pH of the final cleaning solution, when the other constituents were as set forth in Table 1 hereinbelow.
  • Only amine oxides, particularly lauramine oxide were found to elevate the pH to DfE certification levels (a pH of 2.0 or higher), while at the same time providing comparable cleaning performance as the reference prior art cleaning solution (CLR) mentioned above.
  • the solvent is an ether alcohol based solvent, and preferably an alkoxylated glycol. More preferably, the solvent is selected from a group of propylene glycol ethers, such as dipropylene glycol methyl ether, tripropylene glycol methyl ether, dipropylene glycol normal butyl ether and propylene glycol normal butyl ether. Most preferred is a propylene glycol (mono) butyl ether sold under the trade name Dowanol PnB manufactured by Dow Chemical of Midland, Michigan.
  • the solvent is preferably present in the cleaning solution in the range of about 0.50 wt.% to about 3.0 wt.% of the active formula, and most preferably in an amount of about 1.4 wt.% of the active formula.
  • Other solvents may be chosen from glycols based on an ether of preferably the propylene type. Likewise, ethylene type glycol ethers are contemplated for use with the present invention.
  • the diluent is preferably deionized water, which is present in a range of 72.0 wt.% to 83.5 wt.% active in the cleaning solution formula. More preferably, the diluent comprises 77.15 wt.% of the active cleaning formulation.

  • a colorant is preferred for use with the present cleaning solution, which colorant takes the form of a green colorant purchased as Pyla-Cert Green MX-718, which can be purchased from Pylam Products Company, Inc. of Tempe, Arizona.
  • Such colorant is preferably used in a quantity sufficient to provide the desired color, preferably in the amount of 0.0008 wt.% of the active formula.
  • Corrosion inhibitors may also be incorporated into the cleaning solution.
  • the preferred class of corrosion inhibitors are imidazolines such as tall oil hydroxyethyl imidazoline, capryl hydroxyethyl imidazoline, cocoyl hydroxyethyl imidazoline, lauryl hydroxyethyl imidazoline and oleyl hydroxyethyl imidazoline.

  • a cleaning solution according to the first embodiment of the present invention was prepared, by introducing appropriate amounts of the indicated constituents, so as to attain the desired relative weight percentages indicated in Table 1 hereinafter, by first charging deionized water into a tank equipped with a mixer. Lactic acid, in the form of Purac 88-T, was then added to the deionized water in the tank. Next, gluconic acid, in the form of PMP Gluconic Acid, were added into the tank. After addition of the gluconic acid, lauramine oxide, in the form of Mackamine LO, were added to the tank from below the surface of the liquid in the tank to minimize foaming. In production, it is preferred to pump the surfactant in through the bottom of a stainless steel tank.

  • Cleaning Formulation 1 was subjected to testing by an independent laboratory to measure the formulation's ability to remove rust stain from white ceramic tiles, according to a standardized test method (Specialized Technology Resources - STR Test Method Number L/PS-TM-241 - Rust Stain Removal Procedure), and was found to provide an average rust removal rate of 83.4%. Similar testing of a known prior art cleaning solution, conventional Jelmar CLR full strength cleaning solution, yielded an average rust removal rate of only 69.5%.

  • the descaling tests in Table 2 were performed according to a different method from the STR test method described above in Table 1. For Table 2, the descaling tests were performed upon marble test blocks, namely Crema Tumbled Marble Tiles, 9/16" x 9/16" x 3/8". Marble was chosen because it contains calcium carbonate, or limestone. Thus, solutions that descale calcium, lime and rust, must also react with marble and dissolve a portion of it into solution.
  • the blocks were prepared by washing them in distilled water, and drying them in an oven at 120°C (248°F). The blocks were then stored in a closed jar to prevent the absorption of moisture before testing.
  • the blocks were weighed, and placed in a beaker with 15 g of identified cleaning solution being tested. After 5 minutes, the blocks were removed from the cleaning solution being tested, patted dry, and washed several times with distilled water to remove any remaining cleaning solution. Then, the blocks were dried in an oven at 105°C (221 °F) for an hour to remove moisture, and allowed to cool for another hour before weighing.

  • a paper towel was then soaked in the tested cleaning solution for 3 seconds, and then immediately applied to the soiled tile, and scrubbed for 10 seconds.
  • the tile was then wiped by a dry paper towel for another 10 seconds, and set aside to dry for 12 hours before inspection under good light.

  • the formula used in the first solution, JEL-1552 closely matches that of the commercially available CLR® Calcium, Lime and Rust Remover by Jelmar, Inc., which is well known to effectively descale calcium, lime and rust.
  • descaling ability decreased when tested against solutions of higher pH levels. While a higher descaling performance is preferable, there may be other considerations in choosing the appropriate ingredient concentrations of the cleaning solution, including the relative cost of each ingredient, the level of descaling that is necessary, and the pH level of the cleaning solution.
  • the concentrations of the ingredients of the present invention cleaning solution may be altered to still provide an effective hard surface cleaning solution, one that is effective at both removing soap scum as well as descaling calcium, lime and rust.
  • the pH levels of the cleaning solutions of the present invention have been observed to change over time. Namely, the pH levels have been observed to drift higher, with aging of the cleaning solution itself.
  • the pH levels disclosed in Table 2 in the present application and the claims hereto (unless otherwise distinguished), as well as those disclosed in Table 1, all refer to the pH levels of the solutions as measured when each solution was first created. However, solutions that are stored six months or longer, and have been measured at that time, have been observed to have a higher pH level, than the pH level, as measured when the solution was first created.

  • both solutions are capable of removing calcium, lime and rust, at different degrees, as well as soap scum to the same degree.
  • Oven-aging at 40°C has been used to simulate the aging of cosmetic products at a rate of eight times the actual time at room temperature.
  • Oven-aging at 50°C has been used to simulate aging at a rate that is 50% higher than aging at 40°C, or twelve times the actual time at room temperature. Therefore, 19 days at 50°C simulates the aging of the solutions, for approximately 7 1/2 months. This simulated result was confirmed by testing CLR® Calcium, Lime and Rust Remover solutions that had actually been aged more than six months, at room temperature, whose pH levels were similarly found to rise by 0.2 units of pH.
  • sodium hypochlorite bleach was added to the JEL-1552 formula disclosed above.
