Description
~h~ pr~. nf i~Y~-f ~0~1 relates to new and novel dishwashing detergent compos}tions. More particularly, the instant invention concerns a pourable dishwashing detergent gel composition comprising: an RqueoUS xanthan gum thickener, a detergency builder, an alkalinity builder or an alkalinity builder S mixture, a mixture of anionic and non-ionic surfactants, a chelating agent ~ndwater in the form of a gel having a Broolcfield viscosity from about 3,000 to about 6,000 cps and a yield point from about 250 to about 825. The dishwashing detergent can attain additional agents such as dye, perfume, preservatives, corrosion inhibitors, etc.
In recent years, there has been a strong growth in dishwasher machine ~ ownership. This has resulted in a plethera of dishwasher detergents on the market. These detergents to dat~ have been powders, such as Cascade by Proctor ~ Gamble, Electrosol by Economics Laboratory, and Dishwasher All by Lever Brothers. These dishwasher detergents are specially formulated for use in 15 automatic dishwashers and are more fully described in sever~l of the popular magazines, such as Consumers Research Magazine, August, 1977, pp. 14-17 and Consumers Reports, June, 19805 pp. 371-373. The drawbacks of the conventional dishwasher detergents are well described in U.S. patents 4,260,528 to Fox et al and 4,226,736 to Bush et al. The first of said patents describes much related art.
20 The ideal product, according to this patent, despite its high viscosity, must flow easily so it may be dispensed from a tube or plastic squeeze bottle. The productof the patent uses standard, low-foaming surfactants, builders and alkalinity agents to formulate R liquid automatic dishwasher detergent of high viscosity.
- Thickening action is provided by the addition of certain types of thickeners, 25 among which are natural and biopolymeric gums and chemical derivatives thereof.

The urea should be added at a level of about 0.5% to about 8%, and preferably from about
2.0 to 5.096 in order to provide adequate stability without objectionable odor.
30 The products of this patent also have from about 0.3 to about loæ of a polyhydric alcohol selected from thegroup consisting of glycerol, ethylene glycol, propylene glycol and mixtures thereof. The products still further have a Brookfield viscosity from about 13,000 cps to about 150,000 cps~
,. ~
~., 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 5 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 a~ least about 1170 and a Brookfield viscosity of about 472,000 cps.
We have found certain 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 15 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 cycle9 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.
In further detail, our invention relates to a dishwasher gel formulation 20 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 25 proteinaceous soils, reduces the deposition of hard water scale that causes spots and haze, removes tough drie~on soils and is safe for fine china and silver. It is not corroslve to the machine and the contents. Thus, the dishwasher gel detergent composition of the present invention comprises:
(a~ from about 0.5 to about 1.5% of an aqueous xanthan gum thickener;
(b) from about 8 to about 15% of a detergency builder;
,, ~ 5206 39~L AHP-8027 (c) from abou~ 3 to about ~% of an alkalinity builder or an alkalinity builder mixture;
(d~ from about 2 to about 5.596 oî a mixture of anionic and low foamingJ non-ionic surfactants;
(e~ from about 2 to about 9% of chelAging agent; and (f~ water, said composition having a pH of 11-13 and being in the fo}m of a gel characterized a~ having a BrookIield viscosity from about 3,000 to about 7,000 ~ps and a yield point from about 250 to about 825.
More preferably, the dishwasher detergent gel composition of the present invention comprises:
(a) rom about G.8 to about L2% of an aqueous xanthan gum thickener;
(b~ from about 9 to about 14% of a d~tergency builder;
(c) from about 2 to about 4% o~ a first alkalinity builder and about 1 to about 3% of a second alkalinity builder, (d) from about 0.3 to about 1.2% of an anionic surfactant and from about 1.7 to about 4.3% of a non-ionic suria~tant;
(e~ from about 3 to about 5% af a first chelating agent and about 1 to about 4% of a second chelating agent; and (f) water.
Test methods:
(A) Vis~osity: All viscositles of products were measured on a Brookfield Model RVT Synchro-Lectric 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 C3 and the corresponding spindles were 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.
~B) Yield Value: Our values are determined in a manner as in U.S.
Patent 4,266,736. The viscosities are determined, as described above, at 0.3 and0.6 rpm spindle speeds. At these speeds very little shear is placed on the sample.
The values are then applied in the formula:
Yield Value = (aeparent Viscosity at 0.3 rpm) - (apparent Yiscosity at where the viscosities are given in centipoises.
(C) EvaluatiG~ Performance testing on the compositions is done in the following manner, which is a variation of that prescribed by the American Society for Testing and Materials in the "Method for Measurement of Depositions on Glassware During Mecllanical Dishwashing~' (D 3556-76T).
Ten dinner plates were uniformly soiled. Two of each plates had (a) a mixture of margarine and powdered milk, (b~ spinach, ~] eggs, (d) cereal and te)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 1~0 ppm hardness. When using the gel eompositions 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 eaeh cup.
After washing, each soiled dish and each eating utensil was evaluated by a panel of ten. ~ach 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 ~or cleaning and spotting. The spotting evaluation was by a panel of ten according to the following criteria:
no spots, l; spots at random, 2; about 1/4 of surface covered, 3;
about V2 of surface covered, 4; and virtually complete coverage, 5.

Although preferred ingredients are disclosed and claimed7 the obvious equivalents are included within said clairns. E`or example, part of the xanthan gum can be replaced by other thickeners sueh as locust bean gum, tragacanth and/or sodium alginate, provided, however, the viscosity and the yield point remains within the limits hereinO Part o the tetrapotassium polyphosphate can be replaced by other polyphosphates, such as sodium tripolyphosphate;
ethylenediamine tetraacetic acid and gluconic acid can be replaced in part or totally by a water soluble salt thereof or such salt may be formed in situ in the manufacture of the formulation. Other suitable chelating agents are nitrilotriacetic acid or citric acid and the water soluble salts of either, such as the sodium or potassium salt. The NaCO3 alkalinity builder can be substituted by equivalent alkalinity builders such as K2C03 or NaOH, etc. Although sodium metasilicates are preferred, other water soluble silicates such as alkali metal,eg., sodium or potassium, silicates, with varying M~O/SiO2 ratios (alkali metal salt oxide to silicon dioxide) are suitable.

Although preferred ingredients are disclosed and claimed7 the obvious equivalents are included within said clairns. E`or example, part of the xanthan gum can be replaced by other thickeners sueh as locust bean gum, tragacanth and/or sodium alginate, provided, however, the viscosity and the yield point remains within the limits hereinO Part o the tetrapotassium polyphosphate can be replaced by other polyphosphates, such as sodium tripolyphosphate;
ethylenediamine tetraacetic acid and gluconic acid can be replaced in part or totally by a water soluble salt thereof or such salt may be formed in situ in the manufacture of the formulation. Other suitable chelating agents are nitrilotriacetic acid or citric acid and the water soluble salts of either, such as the sodium or potassium salt. The NaCO3 alkalinity builder can be substituted by equivalent alkalinity builders such as K2C03 or NaOH, etc. Although sodium metasilicates are preferred, other water soluble silicates such as alkali metal,eg., sodium or potassium, silicates, with varying M~O/SiO2 ratios (alkali metal salt oxide to silicon dioxide) are suitable.
