Definitions

  • the present invention relates to thickened chlorine bleach compositions.
  • Cleaning compositions are used in everyday life for cleaning a large variety of substrates, such as hard surfaces, textiles and soft furnishings.
  • Many cleaning compositions contain bleaching agents, often in combination with surfactants.
  • Such bleach containing compositions are particularly intended for removing coloured stains such as from textiles or hard surfaces, or for hygienic cleaning of particularly hard surfaces.
  • Active chlorine bleaching agents are very popular for this purpose.
  • Typical materials constituting such hard surfaces include ceramic, metals (e.g. stainless steel, chrome-plated materials) , stone, wood, vitreous enamel, and polymeric surfaces .
  • compositions comprising bleaching agents. Thickened compositions are easier to dispense in a controlled manner. Also, when the compositions are applied on to surfaces to be cleaned, it is desirable that they are in contact with the surface for a sufficiently long time to enable good cleaning. This is especially important when the compositions are applied underneath horizontal surfaces or to vertical or inclined surfaces such as lavatory rims or bowls. Methods to thicken these compositions include the use of polymers or the incorporation of surfactants in high quantities, both of which are expensive options.
  • US 4,839,077 describes a thickened bleach composition
  • a thickened bleach composition comprising: (i) a bleaching halogen compound, (ii) a polymeric thickener having a molecular weight of 1,000 to 100,000 and comprising a charged monomer and an uncharged monomer such ' that the resulting polymer has a acid number . between 80 to 400 mg KOH/g polymer and (iii) a surfactant system including a bleach-resistant nonionic surfactant and a bleach-resistant anionic surfactant.
  • US 5,821,214 describes a cleaning composition comprising: (i) from 0.5 to 10% of soft abrasive particles, (ii) from 0.5 to 2.5% of a chlorine bleach, (iii) from 0.2 to 3% of a thickening system comprising a crosslinked polyacrylate resin having a molecular weight in the range of 1,000,000 to 10,000,000, (iv) from 0.25 to 3% of a bleach stable surfactant system comprising mainly anionic surfactants and (v) sufficient amount of potassium or sodium hydroxide to provide a pH in the range of 11.5 to 13. 5. •
  • JP 10/251,687 describes a liquid bleach composition for hard surface cleaning that comprises: (i) 0.1 to 8% of alkali metal hypochlorite salt, (ii) 0.1 to 9% of alkali metal hydroxide, (iii) 0.1 to 5% of anionic surfactant and (iv) 0.1 to 5% of a buffer which is preferably phosphoric acid or its salts or soluble silicic acid salts.
  • US 6,100,228 describes a bleaching gel cleaner and a method of preparing it comprising: (i) an effective amount of a hypochlorite generating compound, (ii) a ternary thickening system comprising (a) alkali metal soap; (b) a hydrotrope consisting of trialkylamine oxides, betaines and mixtures thereof, iii) bleach stable solvent, and (iv) a buffer/electrolyte to stabilize the composition, the balance being water.
  • hypochlorite bleaching compositions that are thickened using inexpensive and easily available materials.
  • the present invention provides a thickened liquid hypochlorite bleach composition comprising surfactant and alkali metal electrolyte which has sufficient viscosity to be useful for application to a wide range of surfaces, including vertical or inclined surfaces.
  • the thickened liquid bleach compositions comprise water, from 0.1 to 10% of a hypochlorite salt; from 0.5 to 20% of a surfactant; from 0.1 to 8% of an electrolyte selected from the group consisting of alkali metal hydroxides, halides, sulphates, carbonates and mixtures thereof, and the compositions comprise at least two different kinds of alkali metal ions.
  • the bleaching agent in the thickened bleach compositions of the invention is a hypochlorite salt.
  • the cation in the hypochlorite salt may be chosen from alkali metal and alkaline earth metal, preferably alkali metal, more preferably sodium and potassium, most preferably sodium.
  • alkali metal hypochlorites in water also include the corresponding alkali metal chloride. This is due to the method of manufacture of the alkali metal hypochlorite that involves reacting an alkali metal hydroxide with chlorine gas to form the corresponding alkali metal hypochlorite and alkali metal chloride. These are often sold as such without further purification and called ⁇ high salt' bleach. - For example, if the alkali metal is sodium, the high salt' sodium hypochlorite bleach solution also contains sodium chloride.
  • alkali metal hypochlorites which are free of the corresponding chloride.
  • Such products often termed ⁇ low salt' or high purity' bleaches, are prepared by reaction of alkali metal hydroxide with hypochlorous acid.
  • a preferred bleaching agent of the present invention is sodium hypochlorite, due to its wide availability and low cost. It is also preferred to use high salt' sodium hypochlorite bleach in the present invention as it is more widely and cheaply available compared to the corresponding ⁇ low-salt' solutions.
  • the total amount of alkali metal hypochlorite in the compositions of the invention ranges up to 10%, preferably from 0.1 to 8%, more preferably from 1 to 5%.
  • a surfactant that is compatible with hypochlorite is used in the thickened bleach composition of the invention.
  • anionic surfactants for the invention which may be soap or a non-soap surfactants. It is preferred to use non-soap surfactants.

  • Such suitable anionic surfactants include alkali metal salt of alkylbenzene-sulphonates, alkyl-glycerylether sulphates (especially ethers of the alcohols derived from coconut oil and tallow) , primary and secondary alkyl sulphonates, olefin sulphonates, alkyl sulphates, fatty acid monoglyceride sulphates and mixtures thereof.

  • SLES sodium laurylether sulphate
  • surfactants such as nonionic, cationic, amphoteric, or zwitterionic surfactants in the compositions of the invention.
  • the total amount of surfactant in the compositions of the invention ranges from 0.5 to 20%, preferably from 0.5 to 10%.
  • Electrolytes used in the thickened bleach compositions of the invention are selected from the group consisting of alkali metal hydroxides, halides, sulphates, carbonates and mixtures thereof. Preferably they are chosen from hydroxides, halides and sulphates, more preferably hydroxides and halides. Among the halides the chlorides are most preferred.
  • the electrolyte is chosen such that in combination with the hypochlorite the total alkali metal ion content of the composition comprises at least two different alkali metals.
  • One preferred way is to combine one alkali metal hypochlorite with least one alkali metal electrolyte with a different cation.
