Definitions

  • This invention relates to cleaning compositions particularly useful in removing stains from rugs, carpets, and textiles.
  • a wide variety of carpet cleaning and anti-soiling compositions are available for do-it-yourself carpet cleaning. Fluorochemical compounds have been described in the prior art as useful in treating textiles, such as carpets, to impart oil and water repellency and soil resistance.
  • AU-B-0 042 875 describes aqueous carpet cleaning compositions comprising a particular combination of perfluoro polymers and a non-ionic, anionic or amphoteric surfactant, at a pH of 4.0 to 9.5.
  • an aqueous cleaning composition having a pH level falling with a range of from 4 to 9.5 comprising:
  • inventive compositions are stable and are particularly effective in removing a variety of stains from carpeting without contributing to undesirable properties commonly associated with carpet cleaning compositions.
  • One particular group of stains that may be substantially removed from textiles using the inventive compositions are oily stains.
  • inventive compositions are useful in cleaning textiles as well as rugs and carpets. Additionally, prevention of resoiling and stain and dirt repellency are observed as attributes of the composition.
  • the sodium lauryl sulfate component is widely available commercially. It is employed in a range of 0.75% to 1.15% by weight, preferably 0.8% to 1% by weight, and more preferably from 0.85% to 0.9% by weight % (active ingredient), with all weight percentages herein based on the total weight of the composition.
  • the ethylene glycol monohexyl ether is also widely available and is employed within a range of from 0.65% to 0.85% by weight, preferably from 0.7% to 0.8% by weight, and more preferably about 0.75% by weight (active ingredient).
  • the fluorinated surfactant acts primarily as an anti-soiling and anti-staining agent and is a mixture of a perfluoropropionate of Formula I and a perfluoroalkyl phosphate of II, where Formula I is: F(CF 2 ) n -CH 2 CH,-S-CH 2 CH 2 -COOLi wherein n is an integer having a value of 6 to 12 and may be identified as an ⁇ - ⁇ 2-[(2-carboxyethyl)thio]ethyl ⁇ - ⁇ -fluoro-poly-(difluoromethylene) lithium salt, and where Formula II is a mono/diethanolamine salt of a perfluoroalkyl phosphate as represented by the general formula: wherein n is an integer having a value of 6 to 12.
  • the weight ratio of the perfluoropropionate of Formula I to the perfluoroalkyl phosphate of Formula II in the mixture is in the range of from 1:1 to 1:2, and the amount of the mixture employed in the composition is from 0.025% to 0.1% by weight, preferably about 0.1% by weight (active ingredient).
  • a mixture may be purchased from E.I. DuPont de Nemours & Co., Inc. under the chemical name ZONYLTM 7950.
  • the composition also contains a styrene maleic anhydride polymer, available commercially such as, for example, ZELANTM 338, from E.I. DuPont de Nemours & Co., Inc. This ingredient is employed in an amount from 0.025% to 0.05% by weight, and preferably from 0.03% to 0.04% by weight (active ingredient).
  • the chelating agent(s) used are aminopolycarboxylic acid compounds in which the amino nitrogen has attached thereto two or more substituent groups. They are the acids and potassium or sodium salts of ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and N-hydroxyethylethylenediaminetriacetic acid (HEDTA) and mixtures thereof. Most preferred is tetrasodium ethylenediaminetetraacetate (Na 4 EDTA).
  • the chelating agent is used in an amount ranging from 0.3% to 0.45% by weight, preferably from 0.35% to 0.4% by weight, and more preferably from 0.37% to 0.39% by weight (active ingredient).
  • compositions of the invention may include optional ingredients for performing specifically desired functions such as sequestrates, e.g: citric acid, sodium hexametaphosphate, and the like; organic liquid solvents for water-soluble stains, e.g., monohydric aliphatic alcohols having 1 to 6 carbon atoms; corrosion inhibitors such as citric acid, formaldehyde (formalin), sodium citrate, sodium nitrate, ammonia, and so on; preservatives, such as methyl- and ethylparaben, 1,2-benzoisothiazole-3(2H)-ones (including the preservative KATHONTM CG-ICP, available from Rohm and Haas).
  • sequestrates e.g: citric acid, sodium hexametaphosphate, and the like
  • organic liquid solvents for water-soluble stains e.g., monohydric aliphatic alcohols having 1 to 6 carbon atoms
  • corrosion inhibitors such as citric acid, formalde
  • compositions of the invention are formulated as aqueous solutions or emulsions and can be dispensed for use as liquids using conventional dispensing devices such as squeeze bottles fitted with a suitable dispensing nozzle or containers fitted with trigger spray pumps which are well known in the art.
  • the pH of the aqueous compositions of the invention falls within a range of from 4 to 9.5, preferably from 5 to 8, and more preferably between 6 and 7. If the composition requires an pH adjustment to fall within this range, known pH adjusting agents may be employed.
  • the composition may be prepared using conventional techniques known to those skilled in the art.
  • the composition is a substantially clear liquid having the viscosity similar to that of water and may be stored as a stable liquid for extended periods.
  • Carpets are cleaned by applying the composition directly on the carpet, by spraying for example, followed by rubbing the sprayed area with a suitable device, such as, for example, a clean damp cloth or sponge mop, with rinsing of the device until the stain or soil is removed. Textiles may also be cleaned by the composition in a similar manner.
  • a suitable device such as, for example, a clean damp cloth or sponge mop
  • composition of the invention is illustrated by the following examples of specific formulations without, however, being limited thereto.
  • Formulas A and C were prepared by techniques familiar to those skilled in the art using ingredients as shown in the Tables.
  • Formulas A and C were each tested for stability for C weeks at room temperature, 41°C (105°F), 49°C (120°F) and 4°C (40°F). Additionally, the formulas were subjected to a freeze-thaw test for 3 cycles (thaw for 24 hours after freezing). All tests results for Formulas A and C showed the formulas as stable.

  • Table I illustrates the panel results. Out of 21 people panelled, the number of people who gave a response 'yes' to the question on whether the carpet appeared damaged.
  • Table I illustrates the panel results. Out of 21 people panelled, the number of people who gave a response 'yes' to the question on whether the carpet appeared damaged.
  • Table I illustrates the panel results. Out of 21 people panelled, the number of people who gave a response 'yes' to the question on whether the carpet appeared damaged.
  • the data is analyzed using the "Chi Square method" (as described in Statistical Analysis (2nd Edition) by Samuel B. Richmond, the Ronald Press Co., New York, 1964, p. 290-303) at a 95% confidence level, 15 panellists for each product tested per carpet would have had to give a 'yes' response for there to be any significance between the products tested.
  • at most only one panellist saw a difference with the carpet cleaned by Formula A.
  • feline malodor with Formula A was tested as follows. Two Philadelphia: MAINSTREET Cotton Seed carpet samples were stained with 2 g of cat urine obtained by Buckshire Labs, Perkosie, Pennsylvania. One carpet sample was left as the control. One of the carpet samples was then cleaned with 25 g of Formula A by spraying the composition on the carpet and then allowing it to set for 10 minutes. The carpet cleaned was then blotted with white paper towel until the visual stain was gone. The carpet was then dried overnight and subjected to fifteen (15) panellists thereafter. The panel was asked the question: "Is the pet stain removed?" The fifteen (15) panellists responded 'yes' the stain was removed, providing a 95% confidence level (using the Chi-Square method).
  • Each of the carpets were cut into 30.5cm x 30.5cm (12" x 12") pieces. Each carpet piece was treated with 16.6 grams of Formula A and rubbed into the carpet with white paper towel for approximately 50 strokes. The carpets were then allowed to dry overnight. Twenty (20) people were panelled, asking them the following question: "Is the carpet soft, not sticky?"
  • Table III illustrates the panel results.
  • the table shows out of twenty (20) people panelled, how many gave a response of 'yes' to the question asked.
  • Visual Panel Results are shown in Table IV below.
