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.
- the anionic surfactants may have alkali metal or alkaline earth metal or ammonium or alkanolamine counter ions, or a mixture thereof.
- anionic surfactants have been named in the prior art to be suitable for use in hypochlorite solutions, including the water-soluble salts of organic sulphuric acid mono-esters and sulphonic acids having in the molecular structure a branched or straight chain alkyl group containing 8-22 C atoms or an aryl or alkylaryl group containing 8-22 C atoms.
- 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.
- Particularly suitable anionic surfactants for use in the composition of the invention are ethoxylated alcohol sulphates such as SLES (sodium laurylether sulphate) , primary and secondary alkyl 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.
- An alternatively way is to combine a combination of different alkali metal hypochlorites with one or more electrolytes having one or more alkali metal ions.
- the least prevalent alkali metal ion in the composition is present in a molar amount of at least 10% of total alkali metal ions.
- all the components of the composition are chosen such that the total cation content of the composition consists entirely of alkali metal cations.
- the cations comprise only sodium and potassium
- a most preferred embodiment of the invention comprises sodium hypochlorite and at least one electrolyte chosen from potassium hydroxide and potassium chloride in such an amount that at least 10% of total molar amount of alkali metal ion is potassium ion.
- the electrolyte includes agents that ensure that the pH of the thickened bleach composition is at least 11, preferably at least 12.5.
- the total amount of electrolyte in the composition of the invention ranges from of 0.1 to 8%, more preferably from 0.1 to 5.0%.
- composition of the invention comprises water.
- composition of the invention may contain other optional ingredients for enhancing performance and/or aesthetics of the composition such as: solvents, abrasives, structurants, colourants, hydrotropes, whiteners, optical brighteners, soil suspending agents and perfumes.
- compositions according to the invention do generally not require polymeric thickening agents for further thickening and such agents are therefore preferably absent in the compositions.
- composition of the invention is a thickened liquid, which for the purposes of this invention includes easily pourable liquids, thick liquids, gels, pastes and mousses.
- a preferred form is an easily or thick pourable liquid or a gel.
- compositions comprise only one alkali metal ion.
- Comparative Example A A composition corresponding to Comparative Example A was prepared except that 16g of sodium chloride was used instead of the lOg of sodium chloride in the pre-prepared solution. Comparative Example C
- a composition corresponding to Comparative Example A was prepared except that 20g of sodium chloride was used instead of the lOg of sodium chloride in the pre-prepared solution.
- a composition corresponding to Comparative Example A was prepared except that lOg of potassium chloride was added instead of sodium chloride.
- a composition corresponding to Comparative Example B was prepared except that 16g of potassium chloride was added instead of sodium chloride.
- a composition corresponding to Comparative Example C was prepared except that 20g of potassium chloride was added instead of sodium chloride.
- Table 1 lists the compositions of Comparative Examples A, B,C and Examples 1,2,3 along with the weight percent of the ingredients. Table 1 also lists the viscosities of the compositions. The data in Table 1 indicate that for the same total electrolyte concentration, when the alkali metal cation associated with the electrolyte is different to the alkali metal cation associated with the alkali metal hypochlorite, there is a synergistic benefit in terms of increased viscosity of the composition. Table 1
- Comparative Example D A composition was prepared corresponding to Comparative Example B except that 187g of SLES and 93g of secondary alkyl sulphate (SAS) were used instead of 280g of SLES.
- SAS secondary alkyl sulphate
