Description
CREAMY SCOURING COMPOSITIONS
Lellis Francis BRAGANZA
Technical Field The present invention relates to stable, viscous abrasive-containing scouring compositions, which show excellent cleaning, ease-of-rinsing, and shine performance.
These compositions are substantially free of thickener.
Background The formulation of abrasive-containing scouring compositions in creamy form is well-known.
C~ 1 332~08 Such compositions have been disclosed in. e.g. E.P.A. 0 126 545, and E.P.A. 0 216 416, US Patent 4.676.920, and Canadian Patent 1.194.381.
In such state-of-the-art scouring creams, it has always been necessary to incorporate a thickener, in order to adequately suspend the abrasive particles, and give a certain viscosity to the finished product.
It has been found, however, that thickener materials have certain drawbacks, in terms of ease-of-rinsing performance especially. In recent formulations, the level of thickeners has been reduced, but still remains non-negligible .
It has now been found that abrasive-containing creamy scouring compositions can be formulated which are substantially free of thickener.
Indeed, it has been found that certain combinations of surfactant, non-polar solvent, and electrolyte provides the desired viscosity and are capable of suspending high levels of abrasive-particles.
The same combination also provides very good cleaning ease-of-rinsing, and shine performance.
Summary of the Invention The present invention relates to viscous creamy scouring compositions which contain an abrasive in suspension, are substantially free of thickener, and contain a combination of a surfactant, a solvent with a water-solubility under 5%, and an electrolyte.
~ A 1332908 Detailed Description of the Invention Surface-active Agents Water-soluble surfactants useful herein include synthetic anionic, nonionic, amphoteric and zwitterionic surfactants and mixtures thereof.
The anionic surfactants for use herein include C8 18 alkyl benzene sulfates and sulfonates, paraffin sulfonates, olefin sulfonates, and also ethoxylated species such as C8 l8 alkyl polyethoxy sulfates, and sulphosuccinates. Preferred anionic surfactants include C,2 ,4 alkyl benzene sulfonate, and C12,4 alkyl ethoxylated sulfate containing from 1 to 10 ethylene oxide units.
A C,2 ,4 ethoxylated anionic 3 times ethoxylated is sold by AKZ0 under the trade name ELFAN~.
The anionic detersive surfactants are most commonly used in the form of their sodium, potassium or triethanolammonium salts. Nonionic surfactants include alkoxylated (especially ethoxylated) alcohols, alkyl phenols, and amine oxides. Ethoxylated alcohol of the formula RO(CH2CH20)n, with R being a C,2 ,5 alkyl chain and n being a number from 6 to 10, are preferred nonionic surfactants.
The anionic surface-active agents herein are present at levels of from 0.3 to 8%, preferably 3% to 8%.
r A 1 3 3 2~ 08 Preferred are mixtures of non-ethoxylated anionic surfactants and ethoxylated anionic surfactants, at ratios of from 1/1 to 4/1.
Especially suitable are mixtures of alkyl benzene sulfonates and alkyl ethoxylated sulfates.
If present, nonionic surfactants are used at levels of from 0.1% to 6%
by weight of the composition.
The total level of surfactant is from 2% to 10% by weight of the composition.
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 higly 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 aluminium 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.
CA I 332qO8 Typically, abrasives have a particle size range of 10-1000 microns and are used at concentrations of 5% to 50% in the compositions.
Organic solvent Organic solvents for use herein showed have a water-solubility of from O to 5% at 25C in pure, deionised water, preferably less than 1% and most preferably less than 0.5%.
Suitable solvents include hexyl carbitol, 1 (2-n-butoxy-1-methylethoxy) propane-2-o1 (butoxypropoxypropanol), and 2-ethyl-1,3-hexanediol.
Carbitol~ solvents are compounds of the 2-(2-alkoxyethoxy)ethanol class.
Mixtures of solvents can be used, provided the water solubility of the mixture is in the above-specified range. Thus, water-soluble solvents can be used in minor quantities, such as water-soluble carbitol~ solvents including ethyl, propyl or butyl carbitol, and water-soluble cellosolve~ solvents.
The organic solvent is present at levels of from 1% to 10%;
preferably from 2% to 6%.
Electrolyte The electrolytes used in the compositions are selected from the group consisting of alkali metal sulfates, alkali metal carbonates or bicarbonates, alkali metal halides and citrates as well as alkali metal nitrates and mixtures thereof. The electrolytes or their mixture may vary from 0.5% to 8% basis formula weight with the preferred range of about 0.5% to 3.5%, with the alkali metal bicarbonates and carbonates and mixtures thereof being the preferred forms.

Optional inqredients ( In addition to the essential ingredients listed hereinbefore, the present composition can contain additional components, which can be highly desirable.
For example, it is highly preferred that the compositions contain a detergent builder and/or metal ion sequestrant. Compounds classifiable and well-known in the art as detergent builders include the nitrilotriacetates, (NTA), ethylene diamine tetraacetate (EDTA), amino-polyphosphonates (DEQUEST), water-soluble phosphates such as tri-polyphosphate and sodium ortho- and pyro-pho~ph~tes, silicates, and mixtures thereof. These builders are preferably not used in combination with strong abrasives like calcium carbonate, but are recomm~nded 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.
It may be appropriate, as well, to include soaps in the compositions of the invention. Soaps prepared from coconut oil fatty acids are preferred.
Soaps can be used in amounts ranging from 0.2% to 3% by weight of the composition.
