Definitions

  • This invention relates to a concentrate of a cleaning composition containing a bleach compound in the form of a tablet which has excellent foam collapse properties and excellent antibacterial properties grease cutting properties designed in particular for cleaning hard surfaces and which is effective in removing grease soil and/or bath soil and in leaving unrinsed surfaces with a shiny appearance.
  • All-purpose liquid detergents have become widely accepted for cleaning hard surfaces, e.g., painted woodwork and panels, tiled walls, wash bowls, bathtubs, linoleum or tile floors, washable wall paper, etc.
  • Such all-purpose liquids comprise clear and opaque aqueous mixtures of water-soluble synthetic organic detergents and water-soluble detergent builder salts.
  • U.S. Patent No. 4,017,409 teaches that a mixture of paraffin sulfonate and a reduced concentration of inorganic phosphate builder salt should be employed.
  • such compositions are not completely acceptable from an environmental point of view based upon the phosphate content.
  • another alternative to achieving phosphate-free all-purpose liquids has been to use a major proportion of a mixture of anionic and nonionic detergents with minor amounts of glycol ether solvent and organic amine as shown in U.S. Patent No. 3,935,130.
  • an o/w microemulsion is a spontaneously forming colloidal dispersion of "oil" phase particles having a particle size in the range of 25 to 800 A in a continuous aqueous phase.
  • microemulsions are transparent to light and are clear and usually highly stable against phase separation.
  • Patent disclosures relating to use of grease-removal solvents in o/w microemulsions include, for example, European Patent Applications EP 0137615 and EP 0137616 - Herbots et al; European Patent Application EP 0160762 - Johnston et al; and U.S. Patent No. 4,561 ,991 - Herbots et al. Each of these patent disclosures also teaches using at least 5% by weight of grease-removal solvent.
  • compositions of this invention described by Herbots et al. require at least 5% of the mixture of grease-removal solvent and magnesium salt and preferably at least 5% of solvent (which may be a mixture of water-immiscible non-polar solvent with a sparingly soluble slightly polar solvent) and at least 0.1 % magnesium salt.
  • Liquid detergent compositions which include terpenes, such as d-limonene, or other grease-removal solvent, although not disclosed to be in the form of o/w microemulsions, are the subject matter of the following representative patent documents: European Patent Application 0080749; British Patent Specification 1 ,603,047; and U.S. Patent Nos. 4,414,128 and 4,540,505.
  • U.S. Patent No. 4,414,128 broadly discloses an aqueous liquid detergent composition characterized by, by weight:
  • compositions disclosed in this patent include from 0.05% to 2% by weight of an alkali metal, ammonium or alkanolammonium soap of a C13-C24 fatty acid; a calcium sequestrant from 0.5% to 13% by weight; nonaqueous solvent, e.g., alcohols and glycol ethers, up to 10% by weight; and hydrotropes, e.g., urea, ethanolamines, salts of lower alkylaryl sulfonates, up to 10% by weight. All of the formulations shown in the Examples of this patent include relatively large amounts of detergent builder salts which are detrimental to surface shine. Summary of the Invention
  • the present invention provides a cleaning system comprising a concentrate of a cleaning composition in a tablet form which has excellent foam collapse properties, good antibacterial properties and excellent grease cutting property which, when dissolved in a bucket, is suitable for cleaning hard surfaces such as plastic, vitreous and metal surfaces having a shiny finish, oil stained floors, automotive engines and other engines.
  • the improved cleaning compositions with excellent foam collapse properties and excellent grease cutting property exhibit good grease soil removal properties due to the improved interfacial tensions, when used diluted and leave the cleaned surfaces shiny without the need of or requiring only minimal additional rinsing or wiping.
  • the latter characteristic is evidenced by little or no visible residues on the unrinsed cleaned surfaces and, accordingly, overcomes one of the disadvantages of prior art products.
  • these desirable results are accomplished even in the absence of polyphosphate or other inorganic or organic detergent builder salts and also in the complete absence or substantially complete absence of grease-removal solvent.
  • This invention relates to all purpose cleaning detergents in tablet form which quickly dissolve to give a cleaning solution suitable for a variety of household light duty cleaning chores such as in the kitchen or bathroom, etc.
  • the tablet contains a bleach compound and an effervescent system consisting of an organic acid and sodium bicarbonate to give an efficacy signal while dissolving.
  • the tablet can also optionally contain a bleach and two polymeric disintegrants which help disintegrate the tablet when added to water.
  • the tablets can be made either as a single layer tablet with colored speckles for aesthetic benefits or can be a multi-layer tablet with different colored layers.
