Definitions

  • This invention relates to a light duty liquid microemulsion cleaning composition which imparts enhanced mildness to the skin and is designed in particular for dishware and which is effective in removing grease 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.
  • U.S. Patent No. 4,017,409 teaches that a mixture ⁇ 1 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. Again, this approach has not been completely satisfactory and the high levels of organic detergents necessary to achieve cleaning cause foaming which, in turn, leads to the need for thorough rinsing which has been found to be undesirable to today's consumers.
  • 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.
  • 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.
  • the present invention relates to novel light duty liquid microemulsion compositions with high foaming properties, containing a sulfonate surfactant, a salt of an ethoxylated alkyl ether sulfate surfactant, a water insoluble hydrocarbon, cosurfactant, an alkyl sulfoacetate, alkyl carboxylate or dialkyi sulfosuccinate surfactant and water.
  • 4,329,335 also discloses a shampoo containing a betaine surfactant as the major ingredient and minor amounts of a nonionic surfactant and of a fatty acid mono- or di-ethanolamide.
  • U.S. Patent No. 4,259,204 discloses a shampoo comprising 0.8-20% by weight of an anionic phosphoric acid ester and one additional surfactant which may be either anionic, amphoteric, or nonionic.
  • U.S. Patent No. 4,329,334 discloses an anionic-amphoteric based shampoo containing a major amount of anionic surfactant and lesser amounts of a betaine and nonionic surfactants.
  • 3,935,129 discloses a liquid cleaning composition based on the alkali metal silicate content and containing five basic ingredients, namely, urea, glycerin, triethanolamine, an anionic detergent and a nonionic detergent.
  • the silicate content determines the amount of anionic and/or nonionic detergent in the liquid cleaning composition.
  • the foaming property of these detergent compositions is not discussed therein.
  • U.S. Patent No. 4,129,515 discloses a heavy duty liquid detergent for laundering fabrics comprising a mixture of substantially equal amounts of anionic and nonionic surfactants, alkanolamines and magnesium salts, and, optionally, zwitterionic surfactants as suds modifiers.
  • U.S. Patent No. 4,224,195 discloses an aqueous detergent composition for laundering socks or stockings comprising a specific group of nonionic detergents, namely, an ethylene oxide of a secondary alcohol, a specific group of anionic detergents, namely, a sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol, and an amphoteric surfactant which may be a betaine, wherein either the anionic or nonionic surfactant may be the major ingredient.

  • the prior art also discloses detergent compositions containing all nonionic surfactants as shown in U.S. Patent Nos. 4,154,706 and 4,329,336 wherein the shampoo compositions contain a plurality of particular nonionic surfactants in order to effect desirable foaming and detersive properties despite the fact that nonionic surfactants are usually deficient in such properties.
  • U.S. Patent No. 4,013,787 discloses a piperazine based polymer in conditioning and shampoo compositions which may contain all nonionic surfactant or all anionic surfactant.
  • U.S. Patent 4,671 ,895 teaches a liquid detergent composition containing an alcohol sulfate surfactant, a nonionic surfactant, a paraffin sulfonate surfactant, an alkyl ether sulfate surfactant and water.
  • U.S. Patent No. 4,450,091 discloses high viscosity shampoo compositions containing a blend of an amphoteric betaine surfactant, a polyoxybutylene polyoxyethylene nonionic detergent, an anionic surfactant, a fatty acid alkanolamide and a polyoxyalkylene glycol fatty ester. But, none of the exemplified compositions contains an active ingredient mixture wherein the nonionic detergent is present in major proportion, probably due to the low foaming properties of the polyoxybutylene polyoxyethylene nonionic detergent.
  • U.S. Patent No. 4,595,526 describes a composition comprising a nonionic surfactant, a betaine surfactant, an anionic surfactant and a C12-C14 fatty acid monoethanolamide foam stabilizer.

  • the instant formulas explicitly exclude alkali metal silicates and alkali metal builders such as alkali metal polyphosphates, alkali metal carbonates, alkali metal phosphonates and alkali metal citrates because these materials, if used in the instant composition, would cause the composition to have a high pH as well as leaving residue on the surface being cleaned.
  • alkali metal silicates and alkali metal builders such as alkali metal polyphosphates, alkali metal carbonates, alkali metal phosphonates and alkali metal citrates because these materials, if used in the instant composition, would cause the composition to have a high pH as well as leaving residue on the surface being cleaned.
  • the final essential ingredient in the inventive compositions having improved interfacial tension properties is water.
  • the instant compositions exhibit stability at reduced and increased temperatures. More specifically, such compositions remain clear and stable in the range of 5°C to 50°C, especially 10°C to 43°C.
  • the instant compositions have a light transmission of at least 95%.
  • Such compositions exhibi a pH of 5 to 8.
  • the liquid compositions are readily pourable and exhibit a viscosity in the range of 100 to 600 cps as measured at 25°C. with a Brookfield LVT Viscometer using a #2 spindle rotating at 30 RPM. Preferably, the viscosity is maintained in the range of 300 to 500 cps.
  • the instant compositions have a minimum foam height of 110 mis after 55 rotation at 40°C as measured by the foam volume test using 0.75 grams of the composition per liter of water and 1 gram of corn oil per liter of water having a hardness of 300 ppm.
  • composition in wt. % was prepared by simple mixing procedure at 25°C:
  • Miniplate test aims at assessing foam stability/duration of a dish liquid solution (1.25 g/l) in presence f a fat (Crisco Vegetable shortening from P&G). The higher the number the better the product.
