Definitions

  • the present invention relates to viscous abrasive-containing scouring compositions, which show excellent stability, exhibit very good cleaning and shine performance, and are not aggressive towards surfaces to be cleansed therewith, and towards packaging materials.
  • compositions are substantially free of unsaturated terpene solvents, but contain a saturated terpene solvent.
  • creamy scouring compositions containing an abrasive and a binary solvent system constituted of unsaturated terpenes and polar solvents have been disclosed in European Patent Application 0,126,545, published on November 28, 1984.
  • the terpenes both provide cleaning benefits and exhibit desirable emulsification properties during the making process thus enhancing product viscosity.
  • U.S. Patent 4,576,738 discloses liquid hard-surface compositions containing saturated terpenes in combination with a water-soluble solvent.
  • the present invention relates to a viscous creamy scouring compositions containing a surface-active agent, an abrasive, and an organic solvent and if desired conventional additives, characterized in that said cleanser is substantially free of unsaturated terpene solvents and that the organic solvent contains a saturated terpene hydrocarbon.
  • Water-soluble detersive surfactants useful herein include well-known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants and mixtures thereof. Typical of these are the alkyl benzene sulfates and sulfonates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, amine oxides, sulfonates of fatty acids and of fatty acid esters, and the like, which are well-known in the detergency art.
  • such detersive surfactants contain an alkyl group in the C10-C18 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 per mole of hydrophobic moeity.
  • Particular preferred in the compositions of the present invention are: C12-C16 alkyl benzene sulfonates, C12-C18 paraffin-sulfonates and the ethoxylated alcohols of the formula RO(CH2CH2O) n , with R being a C12-C15 alkyl chain and n being a number from 6 to 10.
  • Anionic surfactants are frequently present at levels from 0.3 to 8%, preferably 2 to 4%, of the composition.
  • Nonionic surfactants are used at levels between 0.1% to 6% by weight of the composition. Mixtures of the like surfactants can also be used.
  • the total level of surface-active agents is preferably from 3% to 5%.
  • the abrasive types employed herein are selected from water-insoluble, non-gritty materials well-known in the literature for their relatively mild abrasive properties. It is highly preferred that the abrasives used herein not be undesirably "scratchy". Abrasive materials having a Mohs hardness in the range of about 7, or below, are typically used; abrasives having a Mohs hardness of 3, or below, can be used to avoid scratches on aluminum or stainless steel finishes.
  • Suitable abrasives herein include inorganic materials, especially such materials as calcium carbonate and diatomaceous earth, as well as materials such as Fuller's earth, magnesium carbonate, China clay, attapulgite, calcium hydroxyapatite, calcium orthophosphate, dolomite and the like.
  • the aforesaid inorganic materials can be qualified as "strong abrasives”.
  • Synthetic organic abrasives such as urea-formaldehyde, methyl methacrylate melamine-formaldehyde resins, polyethylene spheres and polyvinylchloride can be advantageously used in order to avoid scratching on certain surfaces, especially plastic surfaces. When such "soft abrasives” are used, strong builders can be incorporated in the composition.
  • abrasives typically have a particle size range of 10-200 microns and are used at concentrations of 5% to 30% in the compositions. Thickeners are frequently added to suspend the abrasives.
  • the organic solvent to be used in the present composition contains saturated terpene hydrocarbons.
  • Saturated terpenes for use herein include the hydrogenated species corresponding to well-known mono- or sesquiterpenes, which can be acyclic or cyclic.
  • Preferred materials for use herein are the hydrogenated mono- and bicyclic monoterpenes, selected from hydrogenated terpinenes, terpinolenes, limonenes, and pinenes.
  • a highly preferred material is hydrogenated pinene, also known as pinane or 2,6,6-trimethyl bicyclo (3.1.1.) heptane.
  • the saturated terpene hydrocarbon herein is used at levels of from 1% to 10% by weight of the composition, preferably 1.5% to 5% by weight.
  • the solvent system can optionally contain polar solvents in combination with the saturated terpene component, in order to further improve cleaning performance.
  • polar solvents with low water solubility like benzyl alcohol, and diols such as 2-ethyl-1,3-hexanediol and 2,2,4-trimethyl-1,3-pentanediol, and solvents with high water-solubility, like water-soluble CARBITOL® solvents or water-soluble CELLOSOLVE® solvents.
  • Water-soluble CARBITOL® solvents are compounds of the 2-(2-alkoxyethoxy)ethanol class wherein the alkoxy group is derived from ethyl, propyl or butyl; a preferred water-soluble carbitol is 2-(2-butoxyethoxy)ethanol also known as butyl carbitol.
  • Water-soluble CELLOSOLVE® solvents are compound of the 2-alkoxyethoxy ethanol class, with 2-butoxyethoxyethanol being preferred.
  • Preferred for use herein is benzyl alcohol.
  • polar solvents can be used in levels ranging from 0.5 to 10% of the composition, preferably 0.5% to 5%, the weight ratio of saturated terpene to polar solvent being in the range from 5:1 to 1:5, preferably 2:1 to 1:2.
  • compositions herein are substantially free of unsaturated terpene-solvents.
  • solvents are generally used at levels exceeding about 2%, unsaturated terpenes cannot be incorporated in the claimed compositions in such proportions.
  • relatively minor sub-additive levels of unsaturated terpenes e.g., below about 0.6% (calculated on the total cleanser composition), can be present originating from conventional ingredients such as perfumes.
  • the present composition can contain additional components, which can be highly desirable.
  • compositions herein can contain a detergent builder and/or metal ion sequestrant.
  • detergent builders include the nitrilotriacetates, (NTA), ethylene diamine tetracetate (EDTA), amino-polyphosphonates (DEQUEST), water-soluble phosphates such as tri-polyphosphate and sodium ortho- and pyro-phosphates, silicates, and mixtures thereof. These builders are preferably not used in combination with strong abrasives like calcium carbonate, but are recommended in combination with soft organic abrasives like polyvinylchloride or soft inorganic abrasives like talc.
  • Metal ion sequestrants of lower metal sequestration constant can advantageously be used in combination with strong or soft abrasives.
  • Those metal ion sequestrants include polycarboxylates and citrates.
  • Preferred builders/sequestrants for use in the present invention are NTA, EDTA, citrates and mixtures thereof. The builders/sequestrant will be present at levels of from 1% to 15%.
  • soaps in the compositions of the invention. Soaps prepared from coconut oil fatty acids are preferred.
  • Soaps are used in amounts ranging from 0.05% by 3% by weight of the composition.
  • Thickeners should preferably be included in the compositions of the invention, in order to suspend the abrasive. However the level will be kept under 2%, preferably from 0.2% to 1.5%. Common thickeners such as the polyacrylates, xanthan gums, carboxymethyl celluloses, swellable smectite clays, and the like, can be used herein.
  • Optional components are also represented by ingredients typically used in commercial products to provide aesthetic or additional product performance benefits.
  • Typical ingredients include pH regulants, perfumes, dyes, optical brighteners, bleaches, soil suspending agents, detersive enzymes, gel-control agents, freeze-thaw stabilizers, bactericides, preservatives, and the like.
  • Another optional 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. It is a particular feature of the present invention, however, that stable formulations can be prepared without the need for hydrotropic materials of this kind.
  • compositions herein typically contain up to about 60% water as a carrier.
  • the water-level can vary in the range from e.g. 50% to 80%.
  • Water-alchol e.g., ethanol, isopropanol, butanol, etc.
  • Alkylated polysaccharides can be used to increase the stability and performance characteristics of the compositions.
  • compositions herein are preferably formulated in the alkaline pH range, generally in the range of pH 8-11, preferably about 10-10.8.
  • Caustics such as sodium hydroxide and sodium carbonate can be used to adjust and buffer the pH as desired.
  • a creamy cleanser was prepared by mixing the listed ingredients in the stated proportions (% by weight).
  • the above composition showed a good product stability and a satisfactory compatibility with polyethylene-packaging material.
  • compositions are prepared:
