Definitions

  • compositions of the invention are effective cleaners which do not corrode tableware, particularly tableware for entertainment or decorative purposes.
  • Such glassware generally has a high refractive index which gives the classic "sparkle" when cut into decorative shapes.
  • the lead content of such tableware is more than about 20% by weight.
  • slow dissolving aluminum salt refers to an aluminum salt that dissolves at a rate to yield less than 0.56 mM aluminum(III) per minute at 42°C.
  • the aluminum is bound to the seguestrant strongly enough to delay interaction of Al(III) with tea stains.
  • Particularly preferred inorganic builders can be selected from the group consisting of sodium tripolyphosphate, potassium pyrophosphate, sodium carbonate, potassium carbonate, sodium bicarbonate, sodium silicate and mixtures thereof.
  • sodium tripolyphosphate concentrations will range from about 2% to about 40%; preferably from about 5% to about 30%.
  • Sodium carbonate and bicarbonate when present can range from about 5% to about 50%; preferably from about 10% to about 30% by weight of the cleaning compositions.
  • Sodium tripolyphosphate and potassium pyrophosphate are preferred builders in gel formulations, where they may be used at from about 3 to about 30%, preferably from about 10 to about 20%.
  • Anionic synthetic detergents can be broadly described as surface active compounds with one or more negatively charged functional groups. Soaps are included within this category.
  • a soap is a C 8 -C 22 alkyl fatty acid salt of an alkali metal, alkaline earth metal, ammonium, alkyl substituted ammonium or alkanolammonium salt. Sodium salts of tallow and coconut fatty acids and mixtures thereof are most common.
  • Another important class of anionic compounds are the water-soluble salts, particularly the alkali metal salts, of organic sulfur reaction products having in their molecular structure an alkyl radical containing from about 8 to 22 carbon atoms and a radical selected from the group consisting of sulfonic and sulfuric acid ester radicals.
  • Organic sulfur based anionic surfactants include the salts of C 10 -C 16 alkylbenzene sulfonates, C, 0 -C 22 alkane sulfonates, C 10 -C 22 alkyl ether sulfates, C, 0 -C 22 alkyl sulfates, C 4 -C 10 dialkylsulfosuccinates, C 10 -C 22 acyl isothionates, alkyl diphenyloxide sulfonates, alkyl napthalene sulfonates, and 2-acetamido hexadecane sulfonates.
  • a, b, c, d, e and f are integers from l to 350 reflecting the respective polyethylene oxide and polypropylene oxide blocks of said polymer.
  • the polyoxyethylene component of the block polymer constitutes at least about 10% of the block polymer.
  • the material preferably has a molecular weight of between about 1,000 and 15,000, more preferably from about 1,500 to about 6,000. These materials are well-known in the art. They are available under the trademark "Pluronic” and "Pluronic R", a product of BASF Corporation. (f) Alkyl glycosides having formula:
  • Examples of commercially available materials from Henkel Techandit GmbH Aktien of Dusseldorf, Germany include APG * 300, 325 and 350 with R 4 being C 9 -C n , n is 0 and p is 1.3, 1.6 and 1.8-2.2 respectively; APG * 500 and 550 with R 4 is C 12 -C j3 , n is 0 and p is 1.3 and 1.8-2.2, respectively; and APG * 600 with R 4 being C ⁇ 2 -C 14 , n is 0 and p is 1.3. Particularly preferred is APG * 600.
  • Amphoteric synthetic detergents can be broadly described as derivatives of aliphatic and tertiary amines, in which the aliphatic radical may be straight chain or branched and wherein one of the aliphatic substituents contain from about 8 to about 18 carbons and one contains an anionic water-solubilizing group, i.e., carboxy, sulpho, sulphato, phosphato or phosphono.
  • an anionic water-solubilizing group i.e., carboxy, sulpho, sulphato, phosphato or phosphono.
  • Examples of compounds falling within this definition are sodium 3-dodecylamino propionate and sodium 2-dodecylamino propane sulfonate.
  • Thickeners are often desirable for liguid cleaning compositions.
  • Thixotropic thickeners such as smectite clays including montmorillonite (bentonite) , hectorite, saponite, and the like may be used to impart viscosity to liguid cleaning compositions.
  • Silica, silica gel, and aluminosilicate may also be used as thickeners.
  • Salts of polyacrylic acid (of molecular weight of from about 300,000 up to 6 million and higher) , including polymers which are cross-linked may also be used alone or in combination with other thickeners.
  • Use of clay thickeners for automatic dishwashing compositions is disclosed for example in U.S. Patent NOS.
  • the amount of thickener employed in the compositions is from 0 to 5%, preferably 0.5-3%.
  • halogen and peroxygen bleach sources may be used in the present invention.
  • examples of such halogen and peroxygen bleaches are described in US Patent No. 5,200,236 issued to Lang et al. , herein incorporated by reference.
  • Preferred peroxygen bleach precursors are sodium p-benzoyloxybenzene sulfonate, N,N,N' ,N' -tetraacetylethylene diamine, sodium nonanoyloxybenzene sulfonate and choline sulfophenyl carbonate.
  • Composition 3 was prepared according to the invention. Sodium citrate in an amount to deliver 0.8 mM in the wash was completely dissolved in water; during dissolution, the pH of the solution was maintained at 9.5. Once the seguestrant completely dissolved, aluminum sulfate to deliver 0.8 mM Al(III) in the wash was added to the solution. The pH of the resulting solution was adjusted to 8.9 to form the premix. This premix was added to the composition described in Example 1 to generate Composition 3.
  • Example 8 Benzoic acid was combined with aluminum sulfate at differing ratios to form a premix according to the invention. The effect of these premixes on tea stain removal was observed.
