Definitions

  • This application relates to new and novel dishwashing detergent compositions. More particularly, the instant invention concerns a pourable dishwashing detergent gel composition comprising: an aqueous xanthan gum
  • the dishwashing detergent can attain additional- agents such as dye, perfume, preservatives,
  • the product of the patent uses standard, low-foaming surfactants, builders and alkalinity agents to formulate a liquid automatic dishwasher detergent of high viscosity. 25 Thickening action is provided by the addition of Certain types of thickeners, among which are natural and biopolymerie gums and chemical derivatives thereof. Stability and flow are controlled by the addition of critical amounts of urea and polyhydr ⁇ c alcohol with appropriate adjustment of the pH.
  • the urea should be added at a level of about 0.5% to about 8%, and preferably from about 30 2.0 to 5.0% in order to provide adequate stability without objectionable odor.
  • Patent No. 4,226,736 discloses a low-foaming machine dishwasher detergent composition comprising an aqueous thickener, non-ionic surfactant and water in the form of a gel having a minimum yield point of at least 1170 so that it will not leak out of a sealed or closed cup, prior to its automatic opening for dispensing the detergent for a second or subsequent wash cycle.
  • This patent discloses multitudeness thickening agents including xanthan gum, although such material is not disclosed in any of the specific examples.
  • the products have a minimum yield point of at least about 1170 and a Brookfield viscosity of about 472,000 cps.
  • pourable gel dishwashing detergents having a relatively low viscosity and a relatively low yield point whereby the gel formulation can be conveniently filled into bottles at the point of manufacture, easily and conveniently poured into dispensing cups of a dishwasher machine by the user.
  • the gel formulation sets up sufficiently in the dishwasher cups so that little or no leakage occurs from a sealed or closed cup, prior to its automatic opening for., dispensing the detergent for a second or subsequent wash cycle, as seen by a satisfactory cleansing of the dishes and silverware in the automatic dishwasher, even though the gel formulation is placed into the sealed cup only.
  • our invention relates to a dishwasher gel formulation which is stable, with a high pH and retains its viscosity.
  • the gel is completely soluble in hot water and completely rinses out from a dishwasher cup without gritty deposits or powder detergent residues. It is pseudoplastic in nature so that it may pour freely and completely from a bottle ⁇ yet set up and resist draining from the machine dishwasher cup. It creates minimal foam even with proteinaceous soils, reduces the deposition of hard water scale that causes spots and haze, removes tough dried-on soils and is safe for fine china and silver. It is not corrosive to the maehine and the contents.
  • the dishwasher gel detergent composition of the present invention comprises:
  • composition having a pH of 11-13 and being in the form of a gel characterized as having a Brookfield viscosity from about 3,000 to about 7,000 cps and a yield point from about 10 250 to about 825.
  • the dishwasher detergent gel composition of the present invention comprises:
  • Viscosity All viscosities of products were measured on a * -" Brookfield Model RVT Synchro-Leetric Viscometer using appropriate speeds and spindles as suggested by the manufacturer. With very gelatinuous materials, with which there is a tendency for the spindle to "bore" a hole in the sample and thus give erroneous readings, a Brookfield Model LVT Viscometer was supported on a Brookfield Helipath Stand (Model C) and the corresponding spindles were 30 used. The Helipath stand slowly lowers the viscometer spindle deeper into the sample so the spindle continuously encounters fresh sample. All viscosities are read at 25° C. just prior to testing the sample for cup retention.
  • Ten dinner plates were uniformly soiled. Two of each plates had (a) a mixture of margarine and powdered milk, (b) spinach, (c) eggs, ( ) cereal and (e) mustard. Seven grams of each of the above soils was placed uniformly in the center area of each of two dinner plates. One gram of the above standard soils was placed on one each knife, fork and spoon. Two grams of milk was placed into each of eight glasses. The soiled items, along with four unsoiled glasses, were placed in a Kitchen Aid Energy Saver IV Superba dishwasher by Hobart. The water supply was adjusted to 140° F. and 150 ppm hardness. When using the el compositions of the present invention, fifty-two grams of detergent, which is approximately three tablespoons, was placed into the second cup; no detergent was placed in the first cup. With the control, forty-one grams of detergent was placed in each cup.
  • each soiled dish and each eating utensil was evaluated by a panel of ten. Each panelist counted the number of particles of soil • remaining up to a maximum of ten. Articles with more than ten particles of soil were rated 10+. Any particle of 10 mm. or larger in any direction was rated 10+.
  • Each soiled and unsoiled glass and each article of silver was examined for spotting and filming; each piece of silver was examined for cleaning and spotting.
  • the spotting evaluation was by a panel of ten according to the following criteria: no spots, 1; spots at random, 2; about 1/4 of surface covered, 3; about 1/2 of surface covered, 4; and virtually complete coverage, 5.
  • the filming evaluation was by a panel of ten according to the followin criteria: none, 1; barely perceptible, 2; slight, 3; moderate, 4; and heavy, 5. The tests were completed five times with the position of the various soiled articles altered each time. The values for each material was averaged together to provide an overall rating.
  • liquid gel dishwasher detergent formulations were made up with the following compositions:
  • Tetrapotassium Detergent 13.0 13.0 10.0 10.0 pyrophosphate Builder Tetrapotassium Detergent 13.0 13.0 10.0 pyrophosphate Builder .

  • Examples and the formulations of Examples 2-4 were tested as to their cleaning capacity, filming and spotting.
  • Formulation 1 is the same as formulation 2 without the preservative, dye and perfume.
  • the results were shown hereinbelow according to the following table using commercially available Cascade, containing 8.7% phosphorus as phosphates, as a control:
  • the products of the present invention average less than about 2.4% phosphorus in the the form of phosphates, or less than about L3 grams for a 3 tablespoon level use (52 grams).
  • the phosphate level is only about one-fifth that of the phosphate level in Cascade.
  • the particular dye and perfume used herein is not critical, provided said dye and/or perfume is stable at the pH of the dishwasher gel composition and 5 does not react with any of the other ingredients in the dishwasher composition. It may be desirable to use sodium sulfite as a preservative for some of the ingredients herein. This is also, however, not critical to the functioning of the present invention, but merely is to increase the shelf life thereof.
