  • aluminum formate aluminum acetate
  • alkali metal aluminum orthophosphates alkali aluminate
  • zincate or berylliate zincate or berylliate.
  • the overall advantage realized is often marginal in view of concomitant problems having as their genesis the objectionable tendency of the cleaning composition and more particularly, the inhibitor compound, to yield unsightly deposits or precipitates on the surface of the substrate treated, not to mention the contacting surfaces of the washing receptacle.
  • the fugitive behavior of the inhibitor material may be such as to substantially vitiate any advantage which might otherwise accrue from its use thereby detracting from commercial feasibility.
  • a primary object of the present invention resides in the provision of compositions advantageously adapted for use in connection with the cleaning of glazed substrates wherein the foregiong and related disadvantages are eliminated or at least mitigated to a substantial extent.
  • Another object of the present invention resides in the provision of cleaning compositions substantially devoid of any tendency to attack the glazed surface of the wide variety of substrates.
  • a further object of the present invention resides in the provision of cleaning compositions wherein problems associated with precipitate formation during actual cleaning are virtually eliminated whereby to yield a surface having an aesthetically pleasing appearance.
  • Yet another object of the present invention resides in the provision of cleaning compositions capable of providing superior cleaning activity, e.g., bleaching, washing, etc.
  • the aluminum compounds contemplated for use in the practice of the present invention and capable of inhibiting overglaze attack are selected from the group consisting of aluminum silicate and aluminum chlorhydroxide. It has been found that this particular combination of aluminum compound and boron compound affords superior protection against overglaze attack without the concomitant precipitate problem evident with the use of other aluminum compounds heretofore utilized as overglaze attack inhibitors. It should be emphasized at this particular juncture that the specific chemical nature of the aluminum compound is of secondary importance, the salient requirement imposed being that such compound be characterized in exhibiting a substantial capacity to inhibit or otherwise suppress overglaze attack under the conditions contemplated for use.
  • the aluminum compounds may be employed in admixtures, the advisability of so proceeding depending primarily upon the requirements of the processor.
  • This particular embodiment offers the singular advantage that the beneficial properties characterizing each of the compounds may be combined and thus exploited in a single application.
  • Nothing critical resides, of course, in the relative proportions of the components comprising the aluminum inhibitor mixture. Implicit in the foregoing is, of course, that the aluminum compound be substantially devoid of any tendency to adversely affect or otherwise impair the essential functional characteristics of the parent composition.
  • the aluminum silicate contemplated for use in the practice of the present invention and capable of inhibiting overglaze attack is a known material. All aluminum silicates irregardless of the method of preparation, function as an effective overglaze protector in an alkaline dishwashing medium.
  • a specific illustrative example comprises the addition of aluminum sulfate to a soluble silicate at about 140F.
  • the precipitated aluminum silicate has the composition Al O -7.8 SiO- and contains 15.6 percent free moisture, 0.83 percent sulfate, and a very small amount of sodium; it has a pH of 7.0, and a density of the packed composition of 0.4g/cc and a density of 0.23g/cc of the loose composition (not tamped).
  • Aluminum silicates having a pH in the range of 5-9 can also be prepared in accordance with the aforedefined procedure by adding a small amount of sodium aluminate to the aluminum sulfate and sodium silicate reaction mixture to obtain an aluminum silicate of the desired pH. Accordingly, it is apparent that conditions of reaction and reactants can be varied to obtain aluminum silicate having specific physical attributes, such as pH, density, degree of hydration, etc.
  • the aluminum chlorhydroxide preferred in the practice of the present invention and capable of inhibiting overglaze attack is a slightly off-white powder believed to have the formula, Al (OH) Cl"2H O where the atomic ratio of Al to Cl is 2:1. lts aluminum content as A1 0 is about 47 percent and a percent solution of the solid has a pH of about 4.2. Aluminum chlorhydroxide is soluble in water in all proportions and forms stable solutions in normally used concentrations (up to about 50 percent). Concentrations above 50 percent became extremely viscous and difficult to handle. Solutions thereof exhibit no significant change in pH even after prolonged periods of standing (2 years) with the pH varying within the range of about 4.0 to about 4.5.
  • a further critical component of the compositions described herein is, of course, the boron compound and more specifically, boric acid, boron trioxide as well as mixtures comprising two or more thereof.
  • the particular proportions of the various boron compound employed in forming any admixture is nowise a critical factor in the practice of the present invention, the objectives of the formulator comprising the paramount consideration in this regard.
  • Each of the aforedescribed boron compound is found to provide significant advantage when utilized in general with the aluminum inhibitor defined above as evidenced by the substantial if not complete elimination of problems associated with precipitate formation.
  • boron trioxide is particularly beneficial in providing manifold advantage i.e., cleaning compositions prepared therewith display exceptional tolerance to moisture, remain free-flowing over protracted time intervals despite subjecting to relatively severe conditions of temperature and humidity while exhibiting no appreciable tendency to cake or harden on standing in packaged form.
  • the relative proportions of aluminum and boron compounds be confined within certain predetermined ranges in order to assure effective negotiation of both the overglaze attack as well as precipitate problems. More particularly, investigation indicates that the weight ratio of aluminum to boron compounds should be maintained within a range from about 0.025 to about 1 with a range of 0.05 to 1 being particularly preferred. Again, it will be recognized that extra-ordinary or unusual requirements may well dictate departures from the aforesaid parameters and will prove highly beneficial.
  • the quantity of aluminum and boron inhibitor selected for use in the composition will be dependent upon the intended use concentration of the product formulated.
  • the combined quantities of aluminum and boron compound will range from small amounts i.e., on the order of about 5 percent by weight of total cleaning composition up to amounts on the order of about 20 percent; the upper limiting concentration value is significant primarily from an economic standpoint.
