Definitions

  • This invention relates to a liquid detergent product, in particular to a non-aqueous product of the type comprising a liquid surfactant phase and a particulate solid detergency builder suspended in the liquid phase.
  • a liquid detergent product in particular to a non-aqueous product of the type comprising a liquid surfactant phase and a particulate solid detergency builder suspended in the liquid phase.
  • Such products are suitable, for example, for the washing of fabrics.
  • Non-aqueous liquid products have been described in the literature in which the suspended solid builder is a phosphate material, such as sodium tripolyphosphate. While technically such products can provide successful cleaning results, there has been pressure in recent years to reduce the level of phosphate in detergent products. Crystalline aluminosilicates or zeolites have been proposed as replacement materials for phosphate builders and their use in powder products has already been wide-spread. The incorporation of zeolites in non-aqueous liquids however is not without difficulties.
  • zeolite materials appear to be capable of catalysing the breakdown of any bleach materials that may be present in the product. Since one of the major advantages of non-aqueous liquids as a product form is the possibility of including various water-sensitive materials such as bleaches, this is a serious problem.
  • Alkalimetal carbonates have also been proposed as phosphate replacers. Their use in powders has necessitated taking steps to avoid or suppress the effect of calcium carbonate crystal growth inhibitors which would otherwise act to retard the reaction between the hardness ions of the wash liquor and the carbonate ions from the alkalimetal carbonate, with a resulting loss in detergency.
  • GB 1437950 (Unilever Case C720) teaches the use of high surface area calcite (ie. having a surface area above 10m2/g) to suppress this effect and encourage crystal growth.
  • a substantially non-aqueous liquid detergent composition comprising a liquid surfactant phase and a solid particulate phase dispersed therein, the particulate phase comprising a detergency builder which is predominantly a water-soluble carbonate material, characterised in that the composition further comprises a calcium carbonate crystal growth inhibiting agent in the form of a water-soluble alkalimetal salt of a carboxylic acid polymer.
  • the liquid phase of the product contains a surfactant.
  • the surfactant may make up all or only part of the liquid phase, the remainder being constituted by a liquid non-surfactant material such as a solvent.
  • the surfactant may be chosen from the liquid surfactants described "Surface Active Agents” Vol. 1, by Schwartz & Perry, Interscience 1949, Vol. 2 by Schwartz, Perry & Berch, Interscience 1958, in the current edition of "McCutcheon's Emulsifiers and Detergents” published by Manufacturing Confectioners Company or in "Tenside-Taschenbuch", H. Stache, 2nd Edn., Carl Hanser Verlag, 1981.
  • nonionic surfactants are especially suitable, most preferably liquid polyalkoxylated nonionic surfactants.
  • Nonionic detergent surfactants are well-known in the art. They normally consist of a water-solubilizing polyalkoxylene or a mono- or di-alkanolamide group in chemical combination with an organic hydrophobic group derived, for example, from alkylphenols in which the alkyl group contains from about 6 to about 12 carbon atoms, dialkylphenols in which each alkyl group contains from 6 to 12 carbon atoms, primary, secondary or tertiary aliphatic alcohols (or alkyl-capped derivatives thereof), preferably having from 8 to 20 carbon atoms, monocarboxylic acids having from 10 to about 24 carbon atoms in the alkyl group and polyoxypropylenes.
  • alkylphenols in which the alkyl group contains from about 6 to about 12 carbon atoms
  • dialkylphenols in which each alkyl group contains from 6 to 12 carbon atoms
  • primary, secondary or tertiary aliphatic alcohols or alkyl-capped derivatives thereof
  • fatty acid mono- and dialkanolamides in which the alkyl group of the fatty acid radical contains from to about 20 carbon atoms and the alkyloyl group having from 1 to 3 carbon atoms.
  • the alkyl group of the fatty acid radical contains from to about 20 carbon atoms and the alkyloyl group having from 1 to 3 carbon atoms.
  • the polyalkoxylene moiety preferably consists of from 2 to 20 groups of ethylene oxide or of ethylene oxide and propylene oxide groups.
  • particularly preferred are those described in the applicants' published European specification EP-A-225,654, especially for use as all or part of the liquid phase.
  • ethoxylated nonionics which are the condensation products of fatty alcohols with from 9 to 15 carbon atoms condensed with from 3 to 11 moles of ethylene oxide.
  • condensation products of C11 ⁇ 13 alcohols with (say) 3 to 7 moles of ethylene oxide may be used as the sole nonionic surfactants or in combination with those of the described in the last-mentioned European specification, especially as all or part of the liquid phase.
  • Suitable nonionics which may be incorporated, preferably at most in minor quantities, comprise the alkyl polysaccharides (polyglycosides/oligosaccharides) such as described in any of specifications US 3,640,998; US 3,346,558; US 4,223,129; EP-A-92,355; EP-A-99,183; EP-A-70,074, '75, '76, '77; EP-A-75,994, '95, '96.
  • alkyl polysaccharides polyglycosides/oligosaccharides
  • Nonionic detergent surfactants normally have molecular weights of up to about 11,000. When mixtures of different nonionic detergent surfactants are used, it is preferred that the mixture is liquid at room temperature.
  • nonionic detergent surfactants with other detergent surfactants such as anionic, cationic or ampholytic detergent surfactants and soaps may also be used.
  • Suitable anionic detergent surfactants which may be used, preferably at most, in minor quantities, are alkali metal, ammonium or alkylolamine salts of alkylbenzene sulphonates having from 10 to 18 carbon atoms in the alkyl group, alkyl and alkylether sulphates having from 10 to 24 carbon atoms in the alkyl group, the alkylether sulphates having from 1 to 5 ethylene oxide groups, olefin sulphonates prepared by sulphonation of C10-C24 alpha-olefins and subsequent neutralization and hydrolysis of the sulphonation reaction product.
  • surfactants which may be used, preferably at most in minor quantities, include alkali metal soaps of a fatty acid, preferably one containing 12 to 18 carbon atoms.
  • Typical such acids are oleic acid, ricinoleic acid and fatty acids derived from caster oil, rapeseed oil, groundnut oil, coconut oil, palmkernal oil or mixtures thereof.
  • the sodium or potassium soaps of these acids can be used.
  • soap can act as further detergency builders or fabric conditioners, other examples of which will be described in more detail hereinbelow. It can also be remarked that the oils mentioned in this paragraph may themselves constitute all or part of the liquid phase, whilst the corresponding low molecular weight fatty acids (triglycerises) can be dispersed as solids or function as structurants.
  • cationic detergent surfactants are aliphatic or aromatic alkyl-di(alkyl) ammonium halides and examples of soaps are the alkali metal salts of C12-C24 fatty acids.
  • Ampholytic detergent surfactants are eg. the sulphobetaines. Combinations of surfactants from within the same, or from different classes may be employed to advantage for optimising structuring and/or cleaning performance.
  • Non-surfactants which are suitable for inclusion in the liquid phase include ethers, polyethers, alkylamines and fatty amines, (especially di- and tri-alkyl- and/or fatty- N - substituted amines), alkyl (or fatty) amides and mono- and di- N -alkyl substituted derivatives thereof, alkyl (or fatty) carboxylic acid lower alkyl esters, ketones, aldehydes, and glycerides.
  • Specific examples include di-alkyl ethers, polyethylene glycols, polyethylene oxides, glymes alkyl ketones (such as acetone), glycerol, glycerol triacetate, propylene glycol, and sorbitol.
  • compositions of the invention may contain the liquid phase in an amount of at least 10% by weight of the total composition.
  • the amount of the liquid phase present in the composition may be as high as about 90%, but in most cases the practical amount will lie between 20 and 70% and preferably between 35 and 50% by weight of the composition.
  • the dispersed particulate solid phase preferably makes up the remainder of the composition.
  • the water-soluble carbonate material used is preferably an alkali metal carbonate such as lithium, sodium or potassium carbonate or a mixture thereof, for reasons of cost and efficiency, although ammonium or substituted ammonium carbonates can be used instead.
  • the amount of the carbonate material in the product can be varied widely but the amount is desirably at least about 10% by weight, preferably not more than 65% by weight. It should be mentioned within this range the higher levels tend to be required under conditions of use at low product concentration, as is usually the practice in North America, and the converse applies at higher product concentrations as tend to be used in Europe. It may also be desirable to limit the carbonate content to a lower figure to decrease the risk of internal damage following any accidental oral ingestion.
  • compositions of the present invention show improved physical stability.
  • compositions according to the present invention preferably also contain one or more other functional ingredients, for example selected from minor amounts of other detergency builders, bleaches, non-building electrolytes such as sodium sulphate and (for hard surface cleaners) abrasives.
  • other functional ingredients for example selected from minor amounts of other detergency builders, bleaches, non-building electrolytes such as sodium sulphate and (for hard surface cleaners) abrasives.
  • the other detergency builders like the water-soluble carbonate material, are materials which counteract the effects of calcium, or other ion, water hardness, by precipitation, by an ion sequestering or ion-exchange effect. They comprise both inorganic and organic builders. They may also be sub-divided into the phosphorus-containing and non-phosphorus types, the latter being preferred in the present invention for environmental reasons.
  • Inorganic builders comprise the various silicate-, borate- and aliminosilicate-type materials, particularly the alkali-metal salt forms. Mixtures of these may also be used.
  • non-phosphorus-containing inorganic builders when present, include water-soluble alkali metal borates, silicates, metasilicates, and crystalline and amorphous alumino silicates. Specific examples include sodium and potassium silicates and zeolites.
  • organic builders include the alkali metal, ammonium and substituted, citrates, succinates, malonates, fatty acid sulphonates, carboxymethoxy succinates, ammonium polyacetates, carboxylates, polycarboxylates, aminopolycarboxylates, polyacetyl carboxylates and polyhydroxsulphonates.
  • Specific examples include sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylenediaminetetraacetic acid, nitrilotriacetic acid, oxydisuccinic acid, melitic acid, benzene polycarboxylic acids and citric acid.
  • organic phosphonate type sequestering agents such as those sold by Monsanto under the tradename of the Dequest range and alkanehydroxy phosphonates.
  • water-soluble carbonate material makes up the major part of the total detergency builder in the product.
  • the carboxylic acid polymer may be a homopolymer or a copolymer having a molecular weight of at least 500 and should be water-soluble. It may be derived from a mono-carboxylic acid or from a di- or poly-carboxylic acid.
  • the polymer will be used in its water-soluble alkali metal salt form.
  • the level of polymer in the composition is advantageously at least 0.5% by weight up to 15% by weight, most preferably from 1% to 10% by weight.

  • non-carboxylic acid monomers such as ethylene, propylene, styrene, ⁇ -methyl styrene, acrylonitrile, acrylamide, vinylacetate, methyl vinyl ketone, acrolein and esters of carboxylic acid monomers such as ethyl acrylate and methacrylate.
  • particulate calcium carbonate should be absent from the product. More specifically the product should contain no more than about 5%, preferably less than 2%, most preferably less than 1% of high surface area calcite.
  • Suitable bleaches include the halogen, particularly chlorine bleaches such as are provided in the form of alkalimetal hypohalites, e.g. hypochlorites.
  • the oxygen bleaches are preferred, for example in the form of an inorganic persalt, preferably with an precursor, or as a peroxy acid compound.
  • the precursor makes the bleaching more effective at lower temperatures, i.e. in the range from ambient temperature to about 60°C, so that such bleach systems are commonly known as low-temperature bleach systems and are well known in the art.
  • the inorganic persalt such as sodium perborate, both the monohydrate and the tetrahydrate, acts to release active oxygen in solution, and the precursor is usually an organic compound having one or more reactive acyl residues, which cause the formation of peracids, the latter providing for a more effective bleaching action at lower temperatures than the peroxybleach compound alone.

  • compositions are substantially non-aqueous, i.e. they little or no free water, preferably no more than 5%, preferably less than 3%, especially less than 1% by weight of the total composition. It has been found by the applicants that the higher the water content, the more likely it is for the viscosity to be too high, or even for setting to occur. However, this may at least in part be overcome by use of higher amounts of, or more effective deflocculants or other dispersants.
  • non-aqueous liquid Since the objective of a non-aqueous liquid will generally be to enable the formulator to avoid the negative influence of water on the components, e.g. causing incompatibility of functional ingredients, it is clearly necessary to avoid the accidental or deliberate addition of water to the product at any stage in its life. For this reason, special precautions are necessary in manufacturing procedures and pack designs for use by the consumer.
