Definitions

  • the present invention relates to an all purpose hard surface cleaning or microemulsion composition containing an analephotropic negatively charged complex.
  • This invention relates to an improved all-purpose liquid cleaner which can be in the form of a microemulsion 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.
  • use of water-soluble inorganic phosphate builder salts was favored in the prior art all-purpose liquids.
  • such early phosphate-containing compositions are described in U.S. Patent Nos. 2,560,839; 3,234,138; 3,350,319; and British Patent No.
  • 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 ⁇ 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; 4,414,128; and 4,540,505.
  • European Patent Application 0080749 British Patent Specification 1 ,603,047; 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:
  • (c ) from 0.5% 10% of a polar solvent having a solubility in water at 15°C in the range of from 0.2% to 10%.
  • Other ingredients present in the formulations 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
  • SUBSTITUTE SHEET (RU-I26) 13% by weight; non-aqueous 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.
  • a pH neutral microemulsion composition based on paraffin sulfonate and ethoxylated nonionic surfactant is able to deliver improved grease cleaning versus built, alkaline compositions. Besides the improved grease cleaning, this approach is much safer to surfaces as well as less aggressive on consumer's hands (Loth et al - U.S. Patent 5,075,026).
  • microemulsion technology provides outstanding oil uptake capacity because of the adjustment of the curvature of the surfactant micelles by the molecules of the cosurfactant.
  • Rod-like micelles are preferred as they can "swallow" oil to become globular without increasing the surface of contact between the hydrophobic core of the micelle and the hydrophilic continuous phase.
  • the instant invention solves this problem by delivering on the solid surface to be cleaned the proper surfactant mixture that best adsorbs on the surface while keeping a good "leaving" character.
  • the instant invention teaches that all purpose cleaning or microemulsion compositions containing an analephotropic complex of an anionic surfactant with an amphoteric or high dipole moment surfactant deliver this desired property.
  • the analephotropic complex adsorbs much better on grease than on silica surface than individual anionic surfactants alone. This results in enhanced capabilities to disperse complex mixtures of grease with embedded particles of soil which are essential for particulate soil removal.
  • the present invention provides an improved, clear, liquid cleaning composition having improved interfacial tension which improves cleaning hard surfaces such as plastic, vitreous and metal surfaces having a shiny finish, oil stained floors, automotive engines and other engines. More particularly, the improved cleaning compositions exhibit good grease soil removal properties due to the improved interfacial tensions, 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.
  • the instant compositions exhibit a grease release effect in that the instant compositions impede or decrease the anchoring of greasy soil on surfaces that have been cleaned with the instant compositions as compared to surfaces cleaned with a commercial composition which means that the grease soiled surface is easier to clean upon subsequent cleanings.
  • 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.
  • the invention generally provides a stable, clear all-purpose, hard surface cleaning composition especially effective in the removal of oily and greasy oil.
  • the cleaning composition includes, on a weight basis: about 3 to about 40 wt. %, more preferably about 5 to about 20 wt.

  • compositions excluded the use of ethoxylated nonionic surfactants formed for the condensation product of primary or secondary alkanols and ethylene oxide or propylene oxides because the use of these ethoxylated nonionic would cause a weakening of the chemical association between the chemical linker and anionic surfactant.
  • the cleaning composition can be in the form of a microemulsion in which case the concentration of the water mixable cosurfactant is about 0 to 50.0 wt. %, preferably 1 wt. % to about 20 wt. % and the concentration of the perfume or water insoluble hydrocarbon is about 0.4 wt. % to about 10.0 wt. %.
  • the perfume is not, per se, a solvent for greasy or oily soil, - even though some perfumes may, in fact, contain as much as 80% of terpenes which are known as good grease solvents - the inventive compositions in dilute form have the capacity to solubilize up to 10 times or more of the weight of the perfume of oily and greasy soil, which is removed or loosened from the hard surface by virtue of the action of the anionic surfactant, said soil being taken up into the oil phase of the o/w microemulsion.
  • the invention generally provides highly concentrated microemulsion compositions in the form of either an oil-in-water (o/w) microemulsion or a water-in-oil (w/o) microemulsion which when diluted with additional water before use can form dilute o/w microemulsion compositions.
