Definitions

  • the invention relates to pourable, homogenous, abrasive, aqueous liquid detergent compositions containing a particulate abrasive which are suited to the cleaning of hard surfaces.
  • Hard surface cleaners containing abrasive particles are well known.
  • Typical compositions comprise one or more surfactants in solution and a plurality of abrasive particles dispersed therein.
  • Typical abrasive materials include minerals such as calcite or dolomite and other materials of relatively high density. In this art it is generally considered necessary to ensure that the abrasive particles remain in suspension in the composition in order that the composition need not be vigorously shaken before use and that sedimentation, or even cementing of precipitated particles, is prevented.
  • one or more surfactant components act as a suspending agent, usually in combination with a dissolved electrolyte.
  • the presence of the electrolyte causes the surfactant component (s) to thicken by the establishment of a lamellar phase.
  • These compositions are generally formulated at a pH above 9.0 especially where calcite is used as the abrasive.
  • Surfactants employed as suspending agents in liquid abrasive cleaners have included, alkyl benzene sulphonates, alcohol sulphates, alcohol ethoxylates, alkyl amido ethoxylates, fatty acid soaps and secondary alkyl sulphonates. Combinations of these surfactants, together with electrolytes are used to form a suspending system as is well known in the art.
  • the fine structure of these suspending systems generally consists of spherical structures ranging from 0.05 to about 10 microns in diameter. These structures are believed to comprise concentric shells of alternating bilayers of surfactant molecules spaced apart by thin water layers.
  • the suspending system is not the only structure which surfactants can form in the presence of water.
  • the above-mentioned surfactants can also form micellar structures which are viscous but are not capable of suspending particles.
  • compositions of surfactant and water may separate into two or more mixed phases with different physical properties. Exactly which structure is adopted by a particular surfactant mix is strongly influenced by the ionic strength of electrolyte in the composition and some surfactant systems can be exceptionally sensitive to changes in ionic strength of the electrolyte.
  • a further problem with liquid abrasive cleaners is their tendency to leave residues which are difficult to rinse away. This is a particular problem with compositions which contain insoluble abrasives. There is therefore a need to improve the performance of abrasive compositions in such as manner that the overall level of abrasive can be reduced so as to improve rinsing performance and reduce the possibility of surface damage by the abrasive.
  • Solvents are well known components of non-abrasive cleaning compositions.
  • Typical solvents used in cleaning compositions include, alcohols (such as ethanol), ethers (such as Butyl Cellosolve [TM] ) , paraffins (such as Isopar L [TM] ) , esters and terpenes (such as d-limonene) .
  • Another known class of solvents are the alkanolamines .
  • EP503219A (P&G) relates to a cleaning composition containing 0.1 - 10% of an alkanolamine.
  • alkanolamine solvent at significant levels in a liquid abrasive cleaner. It is believed that alkanolamines have both electrolyte and solvent properties and can influence the structure of the suspending phase. Consequently, as the temperature of the composition changes, on storage or during transportation, the level of effective electrolyte in the composition will also change and this can result in the breakdown of the suspending phase and precipitation of abrasive particles or even phase-separation of the composition.
  • the present invention provides a liquid abrasive cleaning composition of pH 7-13 which comprises:
  • the alkanolamine acts both as a base and a solvent which improves cleaning and so allows the level of suspended abrasive to be reduced. In turn this is believed to reduce the possibility of abrasive damage to surfaces and improve rinsing performance. It is believed that the presence of the hydrocarbon co-solvent is required to maintain the stability of the alkanolamine based composition when it is subjected to temperature cycling or storage at extremes of temperature.
  • Alkanolamines for use in the compositions of the present invention can be mono- or poly-functional as regards the amine and hydroxy moieties.
  • Preferred alkanolamines are generally of the formulation H 2 N-R ⁇ -OH where Ri is a linear or branched alkyl chain having 2-6 carbons.
  • Suitable alkanolamines include:
  • 2-amino-2-methyl-1-propanol mono- di- and tri- ethanolamine, mono-, di- and tri -isopropanolamine, and, dimethyl-, diethyl or dibutyl ethanolamine,
  • cyclic alkanolamines such as morpholine can also be employed.
  • alkanolamines include: 2-amino-2-methyl- 1-propanol, mono-ethanolamine and di-ethanolamine. These materials are believed to give improved cleaning on tough or aged soils. Of these materials 2-amino-2-methyl-l-propanol (AMP) is particularly preferred. Typical levels of alkanolamine in the compositions of the invention range from l-5%wt. Higher levels of solvent are less desirable as these may attack certain plastics materials. It is particularly preferred to use 2-amino-2-methyl-l- propanol at a level of l-3%wt.
  • Suitable co-solvent include saturated and unsaturated, linear or branched hydrocarbons.
  • Preferred materials include:
  • Particularly suitable terpenes include d-limonene.
  • Particularly preferred paraffins include the material available in the marketplace as 'Shellsol-T' [TM] .
  • Typical levels of co-solvent range from 0.5-5%wt. It is particularly preferred to use terpines at levels l-3%wt. Some of these terpene materials, such as limonene, have the further advantage that they, or impurities present in them, exhibit insect-repellency . We have determined that the terpene materials give better performance at pH's below 11.
  • the straight chain paraffins can be used at higher levels than the terpenes as these materials are less aggressive to plastics. The paraffins are believed to give better performance at pH's above 11.
  • the ratio of the alkanolamine to the hydrocarbon co-solvent falls in the range 3:1-1:3, with ratios of 3:1 to 1:1 being particularly preferred.
  • a portion of the co-solvent can be introduced as a perfume component, although the levels of co-solvent required will generally require the addition of higher levels of this component that would normally be present as a perfume ingredient in cleaning compositions.
  • the terpenes are used in this manner as selected terpenes, such as limonene, have a pleasant citrus smell, whereas paraffins are generally odourless.
  • a dispersed, suspended particulate phase is an essential ingredient of compositions according to the present invention.
  • the dispersed suspended particulate phase comprises a particulate abrasive which is insoluble in the aqueous phase.
  • the abrasive may be soluble and present in such excess that the solubility of the abrasive in the aqueous phase is exceeded and consequently solid abrasive exists in the composition.
  • Preferred abrasives for use in general purpose compositions have a Moh hardness below 6 although higher hardness abrasives can be employed for specialist applications. Lower hardness materials generally give less surface damage.
  • Suitable abrasives can be selected from, particulate zeolites, calcites, silicas, silicates, carbonates, aluminas, bicarbonates, borates, sulphates, and, polymeric materials such as polyethylene.
  • Preferred average (weight average) particle sizes for the abrasive fall in the range 0.5-200 microns, with values of around 10-100 microns being preferred. In this range an acceptable compromise between good cleaning behaviour and low substrate damage is achieved.
  • Preferred levels of abrasive range from 5-70wt% on product, preferably in the range 20-40wt%, most preferably >30wt%. Such levels of abrasive give effective cleaning and good rinsing.
  • the most preferred abrasives are calcium carbonate (as calcite) , mixtures of calcium and magnesium carbonates (as dolomite) , sodium hydrogen carbonate, potassium sulphate, zeolite, alumina, hydrated alumina, feldspar, talc and silica.
  • Calcite and dolomite are particularly preferred due to their low cost, suitable hardness and colour.
  • composition according to the invention will comprise detergent actives which are generally chosen from both anionic and nonionic detergent actives.

L'invention concerne une composition nettoyante abrasive liquide à pH compris entre 7 et 13, qui contient: a) entre 0,1 et 20 % en poids d'un ou de plusieurs tensioactifs formant un système en suspension, b) entre 2 et 80 % en poids d'au moins un abrasif, c) entre 0,5 et 10 % en poids d'alcanolamine C2-C6, et d) entre 0,25 et 10 % en poids d'un cosolvant hydrocarbure. L'alcanolamine fait à la fois office de base et de solvant, ce qui améliore le nettoyage et permet de réduire le niveau d'abrasif en suspension, de manière à réduire le risque d'altération des surfaces à nettoyer et à améliorer les performances en termes de rinçage. Il est supposé que la présence du cosolvant hydrocarbure est nécessaire pour maintenir la stabilité des compositions à des extrêmes de température.
