Abstract

Liquid detergent compositions containing a high-sudsing surfactant, a detergency builder and an abrasive are disclosed. The compositions provide easier and faster cleaning of food soils from kitchenware in hand dishwashing operations.

Description

Background

The invention relates to liquid detergent compositions containing specified amounts and types of insoluble abrasives which are especially useful in the washing of dishes. The compositions also contain high-sudsing surfactants and detergency builders which complement the action of the abrasive.
The use of abrasives in powdered scouring cleansers is well known. Scouring cleansers generally contain a relatively high level of abrasive. When used in the dishwashing process such products provide abrading power to make the removal of cooked, burnt or dried-on foods on kitchenware easier and more convenient. More recently, liquid scouring cleansers containing water-insoluble abrasives have become available. Such liquid compositions are disclosed in U.S. Patents 3,149,078; 3,210,285; 3,210,286; 3,214,380; 3,579,456; 3,623,990; 3,677,954; 3,813,349 and 3,966,432. The use of scouring cleansers, however, is normally in addition to a specific dishwashing product one product being required for removal of non-sticking soils, especially fats and oils, and a second product being required for scouring purposes.
It is an object of the present invention to provide liquid dishwashing compositions containing a high-sudsing surfactant, a detergency builder and an abrasive, the combination being highly effective in removing food soils from kitchenware when used undiluted or in the form of a relatively concentrated water solution, but which is acceptable for hand dishwashing in the dilute water solutions typically used with liquid dishwashing products.

b) a detergency builder
c) a water-insoluble abrasive
d) water.

Surfactant

The compositions of this invention contain from about 15% to about 50% of a surfactant selected from the group consisting of anionic, nonionic, ampholytic, zwitterionic surface active agents and mixtures thereof. Preferred compositions contain from about 25% to about 35% of surfactant by weight of the composition. Especially preferred are anionic surfactants and mixtures of anionic and nonionic surfactants.
Many anionic detergents can be broadly described as the water-soluble salts, particularly the alkali metal, ammonium and amine salts, of organic sulfuric reaction products having in their molecular structure an alkyl radical containing from about 8 to about 22 carbon atoms and a radical selected from the group consisting of sulfonic acid and sulfuric acid ester radicals. Included in the term alkyl is the alkyl portion of high acyl radicals. Examples of the anionic synthetic detergents which can form the surfactant component of the compositions of the present invention are the sodium or potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols (C₈-C₁g carbon atoms) produced by reducing the glycerides of tallow or coconut oil; sodium or potassium alkyl benzene or toluene sulfonates, in which the alkyl group contains from about 9 to about 15 carbon atoms, (the alkyl radical can be a straight or branched aliphatic chain); sodium or potassium paraffin sulfonates and olefin sulfonates in which the alkyl or alkenyl group contains from about 10 to about 20 carbon atoms; sodium alkyl glyceryl ether sulfonates, especially those ethers of the higher alcohols derived from tallow and coconut oil; sodium coconut oil fatty acid monoglyceride sulfates and sulfonates; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfates with about 1 to about 30 units of ethylene oxide per molecule and in which the alkyl radicals contain from 8 to about 12 carbon atoms; the reaction products of fatty acids esterified with isethionic acid and neutralized with sodium hydroxide where, for example, the fatty acids are derived from coconut oil; sodium or potassium salts of fatty acid amides of a methyl tauride in which the fatty acids, for example, are derived from coconut oil and sodium or potassium S-acetoxy- or β-acetamido-alkanesulfonates where the alkane has from 8 to 22 carbon atoms.
Specific examples of alkyl sulfate salts which can be employed in the instant detergent compositions include sodium lauryl alkyl sulfate, sodium stearyl alkyl sulfate sodium palmityl alkyl sulfate, sodium decyl sulfate, sodium myristyl alkyl sulfate, potassium lauryl alkyl sulfate, potassium stearyl alkyl sulfate, potassium decyl sulfate, potassium palmityl alkyl sulfate, potassium myristyl alkyl sulfate, sodium dodecyl sulfate, potassium dodecyl sulfate, potassium tallow alkyl sulfate, sodium tallow alkyl sulfate, sodium coconut alkyl sulfate,.potassium coconut alkyl sulfate and mixtures of these surfactants. Highly preferred alkyl sulfates are sodium coconut alkyl sulfate, potassium coconut alkyl sulfate, potassium lauryl alkyl sulfate and sodium lauryl alkyl sulfate.
Suitable alkylbenzene or alkyltoluene sulfonates include the alkali metal (lithium, sodium, potassium) and alkanolamine salts of straight-or branched-chain alkylbenzene or alkyltoluene sulfonic acids. Alkyl- benzene sulfonic acids useful as precursors for these surfactants include decyl benzene sulfonic acid, undecyl benzene sulfonic acid, dodecyl benzene sulfonic acid, tridecyl benzene sulfonic acid, tetrapropylene benzene sulfonic acid. Preferred sulfonic acids as precursors of the alkyl-benzene sulfonates useful for compositions herein are those in which the alkyl chain is linear and averages about 12 carbon atoms in length. Examples of commercially available alkyl benzene sulfonic acids useful in the present invention include Conoco SA 515, SA 597 all marketed by the Continental Oil Company and Calsoft LAS 99 marketed by the Pilot Chemical Company.
Particularly preferred anionic surfactants useful herein are alkyl ether sulfates having the formula RO(C₂H₄O)_xSO₃M wherein R is alkyl or alkenyl of about 10 to about 20 carbon atoms, x is 1 to 30, and M is a water-soluble cation. The alkyl ether sulfates useful in the present invention are condensation products of ethylene oxide and monohydric alcohols having about 10 to about 20 carbon atoms. Preferably, R has 12 to 18 carton atoms. The alcohols can be derived from natural fats, e.g., coconut oil or tallow, or can be synthetic. Such alcohols are reacted with 1 to 30, and especially 1 to 12, molar proportions of ethylene oxide and the resulting mixture of molecular species is sulfated and neutralized.
Specific examples of alkyl ether sulfates of the present invention are sodium coconut alkyl triethylene glycol ether sulfate, lithium tallow alkyl triethylene glycol ether sulfate, and sodium tallow alkyl hexaoxy- ethylene sulfate. Preferred alkyl ether sulfates are those comprising a mixture of individual compounds, said mixture having an average alkyl chain length of from about 12 to 16 carbon atoms and an average degree of ethoxylation of from about 1 to 12 moles of ethylene oxide.
Additional examples of anionic surfactants useful herein are the compounds which contain two anionic functional groups. These are referred to as di-anionic surfactants. Suitable dianionic surfactants are the disulfonates, disulfates, or mixtures thereof which may be represented by the following formula:
R(SO₃)₂M₂,R(SO₄)₂M₂,R(SO₃)(SO₄)M₂
where R is an acyclic aliphatic hydrocarbyl group having 15 to 20 carbon atoms and M is a water-solubilizing cation, for example, the C₁₅ to C₂₀ disodium 1,2-alkyldisulfates, C₁₅ to C₂₀ dipotassium-l,2-alkyldisulfonates or disulfates, disodium 1,9-hexadecyl disulfates, C₁₅ to C₂₀ disodium 1,2-alkyldisulfonates, disodium 1,9-stearyldisulfates and 6,10-octadecyldisulfates.
Nonionic surface active agents operable in the
instant compositions can be any of three basic types -the alkylene oxide condensates, the amides and the semi-polar nonionics.
The alkylene oxide condensates are broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which can be aliphatic or alkyl aromatic in nature. The length of the hydrophilic or polyoxyalkylene radical which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements.
Examples of such alkylene oxide condensates include:

(1) The condensation products of aliphatic alcohols with ethylene oxide. The alkyl chain of the aliphatic alcohol can either be straight or branched and generally contains from about 8 to about 22 carbon atoms. Examples of such ethoxylated alcohols include the condensation product of about 6 moles of ethylene oxide with 1 mole of tridecanol, myristyl alcohol condensed with about ₁0 moles of ethylene oxide per mole of myristyl alcohol, the condensation product of ethylene oxide with coconut fatty alcohol wherein the coconut alcohol is a mixture of fatty alcohols with alkyl chains varying from 10 to 14 carbon atoms and wherein the condensate contains about 6 moles of ethylene oxide per mole of alcohol, and the condensation product of about 9 moles of ethylene oxide with the above-described coconut alcohol. An example of a commercially available nonionic surfactant of this type includes Neodol 23-6.5 marketed by the Shell Chemical Company.
(2) The polyethylene oxide condensates of alkyl phenols. These compounds include the condensation products of alkyl phenols having an alkyl group containing from about 6 to 12 carbon atoms in either a straight chain or branched chain configuration, with ethylene oxide, the said ethylene oxide being present in amounts equal to 5 to 25 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in such compounds can be derived, for example, from polymerized propylene, diisobutylene, octene, or nonene. Examples of compounds of this type include nonyl phenol condensed with about 9.5 moles of ethylene oxide per mole of nonyl phenol, dodecyl phenol condensed with about 12 moles of ethylene oxide per mole of phenol, dinonyl phenol condensed with about 15 moles of ethylene oxide per mole of phenol, di-isooctyl- phenol condensed with about 15 moles of ethylene oxide per mole of phenol. Commercially available nonionic surfactants of this type include Igepal CO-610 marketed by the GAF Corporation; and Triton X-45, X-114, X-100 and X-102, all marketed by the Rohm and Haas Company.
(3) The condensation products of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The hydrophobic portion of these compounds has a molecular weight of from about 1500 to 1800 and of course exhibits water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water-solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product. Examples of compounds of this type include certain of the commercially available Pluronic surfactants marketed by the Myandotte Chemicals Corporation.
(4) The condensation products of ethylene oxide with the product resulting form the reaction of propylene oxide and ethylene diamine. The hydrophobic base of these products consists of the reaction product of ethylene diamine and excess propylene oxide, said base having a molecular weight of from about 2500 to about 3000. This base is condensed with ethylene oxide to the extent that the condensation product contains from about 40% to about 80% by weight of polyoxyethylene and has a molecular weight of from about 5,000 to about 11,000. Examples of this type of nonionic surfactant include certain of the commercially available Tetronic compounds marketed by the Wyandotte Chemicals Corporation.

Examples of the amide type of nonionic surface active agent include the ammonia, monoethanol and diethanol amides of fatty acids having an acyl moiety of from about 8 to about 18 carbon atoms. These acyl moieties are normally derived from naturally occurring glycerides, e.g., coconut oil, palm oil, soybean oil and tallow, but can be derived synthetically, e.g., by the oxidation of petroleum, or by hydrogenation of carbon monoxide by the Fischer-Tropsch process.
Examples of the semi-polar type of nonionic surface active agents are the amine oxides, phosphine oxides and sulfoxides. These materials are described more fully in Berry, U.S. Patent 3,819,528, issued June 25, 1974, incorporated herein by reference. Particularly preferred are amine oxides of the formula:
wherein R₁ is a C_10-18 alkyl and R2and R₃ are methyl or ethyl.
Ampholytic synthetic detergents can be broadly described as derivatives of aliphatic amines which contain a long chain of about 8 to 18 carbon atoms and an anionic water-solubilizing group, e.g. carboxy, sulfo or sulfato. Examples of compounds falling within this definition are sodium 3-dodecylamino-propionate, sodium-3-dodecylamino propane sulfonate, and dodecyl dimethylammonium hexanoate.
Zwitterionic surface active agents operable in the instant composition are broadly described as internally- neutralized derivatives of aliphatic quaternary ammonium and phosphonium and tertiary sulfonium compounds in which the aliphatic radical can be straight chain or branched, and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfo, sulfato, phosphato, or phosphono.
The level and type of surfactant used in the compositions of this invention provide an initial suds cover to a dishwashing solution and a suds cover after the washing of 8 plates when used at a concentration of 0.07% in 2 gallons of 115°F. water containing 7 grains/ gallon water hardness measured as CaC03, each plate carrying 4.0 ml of a triglyceride containing soil. Suds are generated by mechanical agitation and the suds cover and height measured. A dinner plate carrying the soil is washed successively with the introduction of 4.0 ml of soil each time. An essentially complete suds cover of the washing solution is more important than suds height, but, preferably, the suds cover after the washing of-8 plates is at least about 1/2 inch in height.
The required sudsing characteristic of the compositions of the invention is that necessary to provide the user of the product with an indication of cleaning potential in a dishwashing solution. Soils encountered in dishwashing act as suds depressants and the presence or absence of suds from the surface of a dishwashing solution is a convenient guide to product usage. Mixtures of anionic surfactants and nonionic surfactants, especially amides and amine oxide nonionic surfactants, are particularly preferred in the- compositions of the invention because of their high sudsing characteristics, their suds stability in the presence of food soils and their ability to indicate accurately an adequate level of product usage in the presence of soil. A preferred ratio of anionic surfactants to nonionic surfactants is from about 2:1 to about 10:1 by weight.
Cationic surfactants such as quaternary ammonium compounds can find optional use in the practice of the invention, particularly in compositions containing nonionic surfactants.
