Definitions

This invention relates to cleaning compositions containing tarnish inhibitors and more particularly to polyphosphate and synthetic detergent compositions containing hydroxamic compounds as tarnish inhibitors.
compositions containing polyphosphates and/or synthetic detergents are now widely used for detergent and other purposes.
Aqueous solutions of polyphosphates and some synthetic detergents tend when at certain pH values to tarnish copper, and nickel and copper alloys such as German silver (a nickel-zinc-copper alloy) to a variety of shades from yellow to bluish black, especially if the solutions are at elevated temperatures and are allowed to remain in contact with the metal for several minutes. Since German silver is frequently used for household articles commonly washed in polyphosphatebuilt detergent compositions, it is evident that this is a serious problem. i
polyphosphate and detergent compositions are provided containing a tarnish inhibitor which compositions will not tarnish copper, and nickel and copper alloys such as German silver.
the tarnish inhibitor of the invention is a hydroxamic compound which can take the form of a hydroxamic acid or water-soluble salt thereof.
hydroxamic compounds of the invention are described by the following formula:
R-b-NHO M M is a cation such as hydrogen or a metal and n is an integer equal to the valence of the metal.
R is an aliphatic hydrocarbon group having either a straight or branched chain and can be saturated or unsaturated. The number of carbon atoms in the R chain is not critical, but R should have at least seven carbon atoms. Optimum tarnish inhibiting properties are displayed by compounds in which R has from nine to fifteen carbon atoms. As the chain increases in molecular weight above seventeen carbon atoms, tarnish-inhibiting properties tend to dimin: ish, and larger amounts of compound have to be employed to achieve good inhibition. Therefore usually compounds in which R has over seventeen carbon atoms would not be employed.
Typical R radicals having either straight or branched chains are heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, decynyl, dodecenyl, octadecenyl, octadecadienyl and dodecynyl.
the hydroxamic compound can be used either in the form of the acid or as a water-soluble salt depending upon which is most readily available and least expensive. In some instances the salts have not been isolated but apparently exist in solution.
the alkali metal salts such as the sodium, potassium and ammonium salts are preferred.
the salts of other metals such as barium, silver, iron (ferric), copper, calcium and magnesium, can be used as well, since it is not the salt-forming cation but the hydroxamic acid or its anion which displays the tarnish inhibiting properties.
the hydroxamic acid may exist in the form of a salt different from that present in the dry composition, due to ion exchange with other cations.
hydroxamic compounds are also capable of existing in the following form:
hydroxamic compounds are represented as well by the above formula as by that given first, but for consistency are re ferred to throughout the specification and claims by the name of the first-given form.
d t t e polyph sphate and/ r synthetic deterg p tion sufiicient to give tarnish inhibition when the composition is used in its normal way.
the maximum amount of by: droxamic compound is not critical but more than is. necessary to give the desired effect usually would not be used, and of course an amount in excess of that soluble in the solution would not be used.
the hydroxamic compounds are effective as tarnish inhibitors in both hard and soft water.
tarnish inhibitors of the invention are effective with water-soluble polyphosphates as a class at pH values where such polyphosphates tend to tarnish German silver (usually pH 6 or above) and particularly those polyphosphates identified by the following general formula from which it is seen that both the acids and their various salts are contemplated:
the sodium polyphosphates are preferred.
Pascals salt sodium dimetaphosphate, sodium trimetaphosphate (Knorres salt), sodium tetrametaphosphate and sodium hexametaphosphate (Graham's salt) are examples.
the hydroxamic compound tarnish inhibitors can be incorporated in compositions containing polyphosphates, and in compositions containing synthetic detergents, and are effective to reduce tarnish due to polyphosphate or detergent in each of these types of compositions. They are particularly useful in synthetic detergent compositions which contain one or more polyphosphates as builders and one or more synthetic detergents, i. e., anionic detergents, nonionic detergents, and mixtures thereof. In many instances they display an enhanced tarnish-inhibiting action in the presence of both polyphosphate and detergent.
polyphosphate-built detergent compositions should contain conventional proportions of active detergent, usually within the range between 5 and 40%, polyphosphate in any amount, usually between 5 and 50%, based on the total composition, and the residue builders and inert materials.
hydroxamic compounds are not compatible with cationic detergents and display very poor tarnish inhibiting action in their presence.
hydroxamic compounds are useful with a wide variety of anionic and nonionic synthetic detergents, with and without polyphosphates.
alkyl aryl sulfonates are a class of detergents well known in the art under this name.
One example thereof are the sulfonated phenylpolypropylene alkanes, characterized by the branched chain structure of polypropylene and a tertiary alkyl carbon at the benzene ring, and having the following general structure:
R1 and R2 are alkyl, of the type formula CnH2n+1, and at least one R is a polypropylene group, the whole alkyl group containing preferably twelve to fifteen carbon atoms.
R--CO--N-(CH2)SO3A 1' where A is hydrogen or an alkali metal, i. e., ammonium, sodium, or potassium, n is a small whole number from one to about five, preferably two or three, R is hydrogen, or an alkyl, aryl, or cycloaliphatic group, such as methyl, and R is an alkyl or alkylene radical, such as myristyl, palmityl, oleyl and stearyl. Sodium palmitic tauride,
sodium palmitic methyl tauride, sodium myristic methyl tauride, sodium palmitic-stearic methyl tauride and sodium palmitic methyl amidopropane sulfonate have been found to be particularly suitable for use in the compositions of the invention.
These compounds are prepared by interacting the corresponding aliphatic acid anhydride or halide with an organic aliphatic aminosulfonic acid, such as taurine, NHzCHzCHzSOsH, and the various N- substituted taurines, such as N-methyl taurine, or aminopropane sulfonic acid, NH2(CH2)3SO3H.
an organic aliphatic aminosulfonic acid such as taurine, NHzCHzCHzSOsH
N- substituted taurines such as N-methyl taurine, or aminopropane sulfonic acid, NH2(CH2)3SO3H.
the invention is also applicable to other water-soluble alkyl aromatic sulfonic acids, such as those prepared by alkylating benzene or naphthalene with a kerosene fraction followed by sulfonation to aliphatic sulfonic acids, esters of sulfuric acid with aliphatic alcohols of ten to eighteen carbon atoms, particularly those derived by the reduction of coconut oil, palm oil and like long-chain fatty acids, sulfonated castor oil, esters and ethers of isethionic acid, long-chain fatty acid esters and long-chain alkyl ethers of 1,2-dihydr0xy propane-3-sulfonic acid and sulfuric acid esters of monoglycerides and glycerol monoethers.
the salts of these acids are ordinarily employed.
tarnish inhibitors are also useful with nonionic detergents, such as, for example, alkyl oxyether and ester and thioether and ester detergents having the following general formula:
R is a straight or branched chain saturated or unsaturated hydrocarbon group having from eight to eighteen carbon atoms or an aralkyl group having a straight or branched saturated or unsaturated hydrocarbon group of from eight to eighteen carbon atoms attached to the aryl nucleus, and attached to A through the aryl nucleus
A is selected from the group consisting of ethereal oxygen and sulfur, carboxylic ester and thiocarboxylic ester groups and x is a number from eight to twenty.
R can for example be a straight or branched chain octyl, nonyl, decyl, lauryl, myristyl, cetyl or stearyl group, or an alkyl aryl group such as octyl benzene, nonylbenzene, decylbenzene, stearyl benzene, etc.
R is alkyl
the detergent can be regarded as derived from an alcohol, mercaptan, oxy or thio fatty acid of high molecular weight, by condensation with ethylene oxide.
Typical of this type of alkyl ether are the condensation products or oleyl or dodecyl alcohol or mercaptan with from eight to seventeen moles of ethylene oxide, such as Emulfor ON, Nonic 218 and Sterox SE and SK.
Typical alkyl esters are 61226 and Renex (polyoxyethylene ester of tall oil acids), Sterox CD and Neutronyx 330 and 331 (higher fatty acid esters of polyethylene glycol).
the detergent can be derived from an alkyl phenol or thiophenol.
the ethoxynated alkyl phenols and thiophenols have the following general formula:
R is a straight or branched saturated or unsaturated hydrocarbon group having at least eight carbon atoms up to approximately eighteen carbon atoms
A is oxygen or sulfur and x is a number from eight to twenty.
R can. for example, be a straight or branched chain octyl, nonyl, decyl, lauryl, cetyl, myristyl or stearyl group. Typical are the condensation products of octyl and nonyl phenol and thiophenol with from eight to seventeen moles of ethylene oxide, available commercially underthe trade names NI 8586, Antarox A400, Igepal CA and CO, Triton X-100, Neutronyx 600 and Tergi tol NFX.
the detergent composition can contain supplemental builders including alkali metal and alkaline earth metal sulfates, chlorides, silicates, borates, carbonates, metaphosphates, and orthophosphates, such as sodium silicate, magnesium sulfate, sodium tetraborate, sodium carbonate, sodium sulfate, trisodium phosphate, potassium carbonate, disodium orthophosphate, sodium metaphosphate, calcium sulfate, calcium chloride, sodium chloride, sodium borate and potassium metaphosphate.
the builder should but need not be water-soluble.
organic materials such as starch, polyethylene glyeols, polyvinyl alcohols and salts of carboxymethylcellulose can be used as builders. It has been found that between about 0.1 and 1% of an alkali metal carboxymethylcellulose increases detergency and sudsing.
the builder mixture is so chosen among alkaline, neutral and acidic salts that the composition obtained in an an aqueous 0.14% solution has a pH of 7 or above.
its pH lies within the range from 7 to about since solutions which are more alkaline may be irritating to the skin and tend to weaken some fabrics, particularly woolens.
the alkali metal carbonates are preferred agents for bringing the pH of the solution to a high alkaline value within the preferred range.
the detergent composition is prepared by conventional methods, as by blending the ingredients thereof in an aqueous solution or slurry and then drying the resulting mixture in a spray or drum dryer at elevated temperatures.
the tarnish inhibitor may be added to the poly-phosphate or detergent composition at any stage of its manufacture, to the finished polyphosphate or detergent composition, or to the polyphosphate or detergent solution.
Hydroxamic compound 0.067 to 0.53% based on the weight of the polyphosphates.
the caprylyl hydroxamic acid having a seven carbon alkyl radical and the potassium stearyl hydroxamate having a seventeen carbon atom alkyl group display the poorest tarnishing inhibiting properties, but even these give fair to excellent protection at the higher inhibitor concentrations.
the potassium lauryl hydroxamate, having an eleven carbon alkyl group gives the best results. These results show the eifect of the chain length of the alkyl group on the potency of the tarnishing inhibiting properties of the hydroxamic compound.
EXAMPLE 7 A test was conducted to determine whether cotton cloth washed with detergent compositions of the invention using water containing 50 p. p. m. ferric iron would become discolored due to formation of the red colored ferric salt-hydroxamate complex.
a solution was prepared having a 0.14% concentration of the composition of Example 3, and the cloth stirred in the solution for twenty minutes at F. The cloth was identical in appearance after drying and pressing with a similar cloth washed in a similar solution without the hydroxamate.
simulated rust spots were applied to a cotton cloth which was then washed as described above except that no iron was added to the water. Although the iron spots were still evident after the washing, the hydroxamate had not changed theircolor.
Detergent solutions were prepared of compositions hav- G /qt of ing the formulations listed in the table.
the solution i concentrations were equivalent to g. of the dry com- 5 Detergent 0.90 positlon per quart of water.
the inhibitor used in each Sodium tripolyphosphate 2 25 case was potassium dodecanohydroxamate (0.27%). Potassium dodecanohydmxamate 0006 Table III 1 Percent Composition of Example No.
Table VI Commercial grade, principally sodium lauryl sulfate with small proportion of other higher fatty alcohol sulfates (sodium salt).
Detergent solutions were prepared, dissolving the detergent (listed in the table below) polyphosphate and inhibitor separately to make up a concentration equivalent to 5 g. of the complete formula per quart of water, and

a non-soap detergent composition comprising an of the trimetaphosphate solution dropped to about 7.5.
compositions containing tarnish inhibitors of the invention do not tarnish copper, nickel-copper-zinc alloys such as German silver, coinage nickel or brass, which normally tarnish when exposed to aqueous solutions containing polyphosphates and/ or synthetic detergents. It is not possible at this time to explain why the compounds of the invention are effective tarnish inhibitors. However it has been observed that when a German silver utensil is immersed for a period in an inhibitorand polyphosphatecontaining detergent solution, and then immersed in a polyphosphate-containing detergent solution not containing inhibitor, only slight tarnishing results. This is taken as an indication that the inhibitor is preferentially adsorbed by the metal, and that this is important in tarnish prevention, but of course such evidence is not conclusive.
