Definitions

  • This invention relates to aqueous detergent compositions suitable for use as general purpose household cleaning compositions.
  • Powdered compositions consist mainly of builder or buffering salts such as phosphates, carbonates, silicates, etc., and although such compositions may display good inorganic soil removal, they are generally deficient in cleaning ability on organic soils such as the greasy/fatty/oily soils typically found in the domestic environment. Moreover, they are diluted with water prior to use.
  • Liquid cleaning compositions on the other hand, have the great advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of surfactant material is delivered directly to the soil. Moreover, it is a rather more straightforward task to incorporate high concentrations of anionic or nonionic surfactant in a liquid rather than a granular composition. For both these reasons, therefore, liquid cleaning compositions have the potential to provide superior grease and oily soil removal over powdered cleaning compositions.
  • liquid cleaning compositions still suffer a number of drawbacks which can limit their consumer acceptability.
  • they generally contain little or no detergency builder salts and consequently they tend to have poor cleaning performance on particulate soil and also lack "robustness" under varying water hardness levels.
  • they can suffer problems of product form, in particular, inhomogeneity, lack of clarity, or inadequate viscosity characteristics for consumer use.
  • the higher in- product and in-use surfactant concentration necessary for improved grease handling raises problems of extensive suds formation, which require frequent rinsing and wiping by the user.
  • oversudsing may be controlled to some extent by incorporating a suds-regulating material such as hydrophobic silica and/or silicone or soap, this in itself can raise problems of poor product stability and homogeneity, and problems associated with deposition of insoluble particulate or soap residues on the items or surfaces being cleaned, leading to filming, streaking and spotting.
  • a suds-regulating material such as hydrophobic silica and/or silicone or soap
  • the said terpenes provide excellent cleaning characteristics across the range of water hardness on grease/oily soils and iorganic particulate soils, as well as on shoe polish, marker ink, bath tub soil etc., and excellent shine performance with low soil redeposition and little or no propensity to cause filming, streaking or spotting on surfaces washed therewith.
  • the terpenes herein specified, and in particular those of the hydrocarbon class are valuable in regulating the sudsing behaviour of the instant compositions in both hard and soft water and under both diluted and neat or concentrated usage, while terpenes of the terpene alcohol class are also valuable for providing effective control of product viscosity characteristics.
  • Terpenes are, of course, well-known components of perfume compositions and are often incorporated into detergent compositions at low levels via the perfume. Certain terpenes have also been included in detergent compositions at higher levels; for instance, DE-A-21 13 732 discloses the use of aliphatic and alicyclic terpenes as anti-microbial agents in washing compositions; GB-A-1.308.190 teaches the use of dipentenes in a thixotropic liquid detergent suspension base composition.
  • DE-A-27 09 690 teaches the use of pine oil (a mixture mainly of terpene alcohols) in liquid hard surface cleaning compositions.
  • EP-A-0040882 published 2.12.81 teaches the use of mono- or sesquiterpenes with solvents such as benzyl alcohol and ethylene glycol dibutyl ether in liquid cleanser compositions.
  • the present invention provides liquid detergent compositions which are stable, homogeneous liquids having excellent suds control across a broad range of usage and water hardness conditions and which provide excellent shine performance together with improved cleaning characteristics both on greasy/oily soils and on inorganic particulate soils, with little tendency to cause filming or streaking on washed surfaces.
  • Preferred terpenes are monocyclic and bicyclic monoterpenes, especially those of the hydrocarbon class, which include the terpinenes, terpineolenes, limonenes and pinenes, and mixtures thereof. Highly preferred materials of this type are d-limonene, dipentene, a-pinene, ⁇ -pinene and the mixture of terpene hydrocarbons obtained from the essence of oranges (e.g. cold- pressed orange terpenes and orange terpene oil phase ex fruitjuice). These terpenes are used at concentrations of at least 0.5%, preferably 1% to 10%, most preferably 2%-6%, in the compositions.
  • Terpene alcohols aldehydes and ketones can optionally be used, but are not as preferred as the terpenes noted above.
  • the terpene alcohols do provide valuable and unexpected improvements in viscosity regulation when incorporated in the compositions of this invention at concentrations from 1% to 3%, more preferably from 1.5% to 2.5%.
  • This component of the present compositions is commercially available as 2-(2-butoxyethoxy)-ethanol, and is otherwise known as diethylene glycol monobutyl ether (C B H, 8 0 3 )-
  • Butyl Carbitol is used in the present compositions at a concentration of at least 0.5%, preferably from 0.5% to 10%, by weight of composition.
  • Butyl Carbitol has unexpected advantages over solvents like benzyl alcohol: it has none of the cloying odor associated with benzyl alcohol and oxidation products thereof; it performs well as a grease remover; it acts, at least partially, as a hydrotrope, thereby allowing lower levels of hydrotropes like cumene sulfonate to be used in the present compositions.
  • Water-soluble detersive surfactants useful herein include well-known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants. Typical of these are the alkyl benzene sulfates and sulfonates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, amine oxides, a-sulfonates of fatty acids and of fatty acid esters, and the like, which are well-known from the detergency art.
  • detersive surfactants contain an alkyl group in the C 10 -C 18 range; the anionic detersive surfactants are most commonly used in the form of their sodium, potassium or triethanolammonium salts; the nonionics generally contain from 3 to 17 ethylene oxide groups.
  • U.S. Patents 4.111.855 and 3.995,669 contain detailed listings of such typical detersive surfactants.
  • C 12 -C 16 alkyl benzene sulfonates and C, 2 -C, 8 paraffin-sulfonates are especially preferred in the compositions of the present type.
  • the surfactant component can comprise as little as 0.1% of the compositions herein when formulated as a spray-on type product.
  • the compositions herein When formulated as standard liquid cleaners, the compositions herein generally will contain 1% to 20%, preferably 2% to 8%, of surfactant.
  • compositions herein can contain other ingredients which aid in their cleaning performance.
  • a detergent builder and/or metal ion sequestrant include the nitrilotriacetates, polycarboxylates, citrates, water-soluble phosphates, mixtures of ortho- and pyro-phosphates, zeolites, especially hydrated zeolite A in the 1-10 micrometer particle size range, and mixtures thereof.
  • Metal ion sequestrants include all of the above, plus materials like ethylenediaminetetraacetate, the amino-polyphosphonates and phosphates (Dequest@) and a wide variety of other poly-functional organic acids and salts too numerous to mention in detail here. See U.S. Patent 3,579,454 for typical examples of the use of such materials in various cleaning compositions.
  • the builder/sequestrant will comprise 1% to 25% of the composition.
  • water-soluble builder/sequestrants are used if clear, homogeneous compositions are desired.
  • Citric acid (2%-10% as sodium citrate) is preferred herein.
  • soaps especially the alkali, ammonium and alkanolammonium salts of C 13 -C 24 fatty acids, are especially useful as suds suppressors when conjointly present with terpenes and Butyl Carbitol in the instant compositions.
  • Soap concentrations of at least 0.005%, preferably 0.05% to 2%, provide this important suds control function.
  • Soap prepared from coconut oil fatty acids is preferred.
  • compositions herein may optionally be thickened. Thickened compositions tend to cling to vertical surfaces such as walls and windows, which makes them more convenient to use. It has been found that many common thickeners undesirably flocculate the compositions herein. However, it has been discovered that thickeners based on Xanthan polysaccharides are effective, non-flocculating thickeners. In general, such Xanthan thickeners are used herein at levels of 0.01% and higher, depending on the desires of the formulator.
  • compositions herein can contain, in addition to ingredients already mentioned, various optional ingredients typically used in commercial products to provide aesthetic or additional product performance benefits.
  • Typical ingredients include pH regulants, perfumes, dyes, optical brighteners, soil suspending agents, detersive enzymes, gel-control agents, freeze-thaw stabilizers, bactericides, preservatives and the like.
  • hydrotropes Another additional ingredient for use herein is represented by conventional detergent hydrotropes.
  • suitable hydrotropes are urea, monoethanolamine, diethanolamine, triethanolamine and the sodium, potassium, ammonium and alkanol ammonium salts of xylene-, toluene-, ethylbenzene- and isopropyl-benzene sulfonates.
  • These hydrotropes can be added to the compositions of the present invention in amounts up to 10% by weight. It is a particular feature of the present invention, however, that stable, homogeneous formulations can be prepared without the need for hydrotropic materials of this kind, or with only very minor levels such as amount of from 0 to 4% (up to 4%) by weight.
  • compositions herein are formulated in the alkaline pH range, generally in the range of pH 8-11, preferably 10-10.8.
  • Caustics such as sodium hydroxide and sodium carbonate can be used to adjust and buffer the pH, as desired.
  • compositions herein are in liquid form, they can be prepared by simply blending the essential and optional ingredients in water.
  • Example I exhibits excellent grease removal from asphalt tile when applied neat, or as a 1-15% aqueous solution. Excessive sudsing is not a problem if usage concentrations are below 10% in water.
  • Example II exhibits good freeze-thaw stability, an excellent low suds profile, excellent odor quality and has a desirable viscosity in the range of 0.15 g.cm -1 .s -1.
  • the product is conveniently used neat, or in a 1-50% aqueous solution, to remove all manner of greasy oily stains from hard surfaces.
  • Example III is prepared as a fully-formulated liquid cleanser suitable for use in water in the hardness range of 0.12 to 0.22 gram per liter.
  • the composition provides excellent removal of both greasy and solid soils from all manner of surfaces.
