Definitions
- the present invention relates to stable, viscous abrasive-containing scouring compositions, which show excellent cleaning, ease-of-rinsing, and shine performance, and are not aggressive to surfaces to be cleansed therewith and packaging materials.
- compositions are substantially free of terpene solvents, and contain a narrowly-defined solvent derived from propylene glycol.
- creamy scouring compositions containing an abrasive and binary solvent system constituted of terpenes and polar solvents have been disclosed in European Patent Application 0,126,545, published on November 28, 1984.
- the terpenes show both cleaning and desirable emulsification properties, which enhance product viscosity.
- viscous terpene solvent free creamy scouring cleanser compositions showing remarkable cleaning efficiency, ease-of-rinsing and surface-compatibility, can be formulated which contain a narrowly-defined solvent derived from propylene glycol.
- the present invention relates to a viscous creamy scouring cleanser being substantially free of terpene solvents, containing a surface-active agent, an abrasive, and an organic solvent and if desired conventional additives, characterized in that said cleanser is free of or contains not more than 2% by weight of terpene solvents and that the organic solvent is represented by the formula: wherein R is a C1 to C8 alkyl, alkenyl or alkyl aryl group, preferably a C1 to C4 alkyl group, and n is an integer from 1 to 4, preferably 1 or 2; and that the Mohs hardness of the abrasive is 7 or less.
- 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 sufactants 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 agent is preferably from 3% to 5%.
- Abrasive - 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 of 7, or below, are 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 10-1000 ⁇ m and are used at concentrations of 5% to 30% in the compositions. Thickeners are frequently added to suspend the abrasives.
- the organic solvent - The organic solvent to be used in the present composition has the general formula wherein R is an alkyl, alkenyl, or alkyl-aryl group having from 1 to 8 carbon atoms, and n is an integer from 1 to 4.
- R is a alkyl group containing 1 to 4 carbon atoms, and n is 1 or 2.
- Especially preferred R groups are n-butyl or isobutyl.
- 1-n-butoxypropane-2-ol is especially preferred.
- the organic solvent herein is preferably used at levels of from 2 to 10% by weight of the composition, more preferably 4 to 6%.
- the solvent system can optionally contain, in combination with the solvent described hereinabove, water-soluble CARBITOL® solvents or water-soluble CELLOSOLVE® solvents.
- Water-soluble CARBITOL® solvents are compounds of the 2-(2-alkoxyethyoxy)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-alkoxy ethanol class, with 2-butyl ethanol being preferred.
- Suitable solvents to be used with the solvents of the invention are also benzyl alcohol, and diols such as 2-ethyl-2,3-hexanediol and 2,2,4-trimethyl-1,3-pentanediol.
- co-solvents can be used in levels ranging from 0.1 to 5% of the composition.
- compositions herein are substantially free of terpene-solvents.
- solvents are generally used at levels exceeding 2%, terpenes cannot be incorporated in the claimed compositions in such proportions.
- relatively minor sub-additive levels of terpenes e.g., below 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 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 pryo-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.
- 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, 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%, preferably from 2% to 7%.
- soaps in the compositions of the invention. Soaps prepared from coconut oil fatty acids are preferred.
- Soaps are used in amounts ranging from 0.2% to 3% by weight of the composition, preferably in an amount in excess of 1%, typically from 1% to 2% by weight.
- 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 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, 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 90% water as a carrier.
- 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 preferbly 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.
- Creamy cleansers were prepared by mixing the listed ingredients in the stated proportions (% by weight).
- test-soils were prepared as follows.
- the plates are placed in the oven at 115°C ("soft soil”) or 170°C (“hard soil”) for 2 hours and then allowed to age at least 1 day.
- the testing conditions were as follows:
