Cl. ..Clld 7/54 [58] Field of Search ..282/99, 89, 135, 389, DIG. 1; 17 Claims, N0 Drawings In order to obtain a satisfactory detergent action in hard water, it is necessary in most detergent compositions to include a sequestrant that is capable of capturing calcium and magnesium ions present in the hard water, and reducing their concentration in the washing solution to less than g./l. Pentasodium tripolyphosphate is widely used for this purpose. However, the use of phosphates in detergent compositions is no longer favored, because the phosphate content in the wash water has a considerable nutrient value, and if high phosphate waste waters find their way into fresh water streams and lakes, the growth of plant life therein is greatly accelerated, leading even to a choking up of the water courses. Since detergent formulations of the synthetic detergent type are now widely used, it is important to formulate them with nonor low-phosphate sequestrants.
Sequestrants of the aminocarboxylic acid type, such as ethylene diamine tetraacetic acid and nitriloacetic acid, and their alkali metal and amine salts, are capable of reducing the calcium and magnesium ion concentration in hard water to the desired low level, but they strongly increase the corrosive attack of detergent solutions containing them on copper, zinc and aluminum, as well as metal alloys containing these metals. Such corrosive attack is accentuated if the detergent composition also includes bleaching agents of the peroxide type. Since copper, zinc and aluminum and their alloys are widely used in dishwashing and clothes washing machines, for example, in the protective conduits for the electric heating elements, which are of nickel-plated copper, in brass valve seats, in copper liquid thermometers, in zinc alloy pump wheels, and in zinc-plated steel outer drums, in pump casings,.and the like, such corrosion presents a particularly serious problem, and must be inhibited if such sequestrants'are to be used in detergent formulations.
Phosphoric acid esters of alkyl glyceryl ethers, and phosphoric acid esters of ethylene oxide adducts of fatty alcohols have been proposed as inhibitors of the corrosive effect of detergent compositions containing aminocarboxylic acid chelating agents. However, the effectiveness of these phosphoric acid esters is greatly reduced in the presence of bleaching or oxidizing agents, so that these esters are not capable of imparting a sufficient corrosion inhibiting effect to detergent formulations containing or to be used with a bleaching agent.
The salts of monocetyl and monostearyl phosphates are good metal corrosion inhibitors in detergent compositions based on nonionic and/or anionic surfactants, but these alkyl phosphates form difficultly soluble calcium and magnesium salts. Consequently, they cannot be employed in detergent formulations intended for use in hard water, unless sequestrants are also present. However, these alkyl phosphates are relatively ineffective in inhibiting the corrosive effect of aminocarboxylic acid sequestrants, such as ethylene diamine 'tetraacetic acid and propylene diamine tetraacetic acid.
In accordance with the invention, it has been determined that monoalkyl oxypropylene phosphoric acid esters display excellent corrosion-inhibiting properties in synthetic surfactant detergent or washing compositions containing aminocarboxylic acid sequestrants and bleaching or oxidizing agents, such as'peroxides, and demonstrate this effect in both soft and hard water. The monoalkyl oxypropylene phosphoric acid esters can be used either in acid form or in salt form. If the acid form is used, the salt form may be formed in situ in the aqueous detergent or washing solution.
The monoalkyl oxypropylene phosphoric acid ester corrosion inhibitors in accordance with the invention are defined by the following general formula:
In the above formula, R is a straight or branched chain alkyl radical having from 5 about to about b and preferably from 16 to 18 carbon atoms.
M is hydrogen, an alkali metal, such as sodium or potassium, ammonium or a strongly basic organic amine, such as tributylamine, monoethanolamine, diethanolamine, or triethanolamine.
n is a number representing the average number of propylene oxide ether units, and is within the range from about I to about 4, and preferably 1 or 2. It will be understood that when n is greater than 1, mixtures can be present, and probably will be, when propylene oxide is condensed with the alcohol. In such cases, It represents an average number, and can be any fractional number within the range from 1 to 4, for instance, 1.2, 2.5 or 3.3.
R can be, for example, pentadecyl, palmityl (cetyl), margaryl, stearyl, nonadecyl, and arachidyl.
Exemplary monoalkyl oxypropylene phosphoric acid esters monopalmityltri(oxypropylene) phosphoric acid, monostearyldi(oxy-propylene)phosphoric acid, monomargaryldi(oxypropylene)phosphoric acid, monononadecyl 0xypropylene phosphoric acid, monoarachidyl oxypropylene phosphoric acid, monostearyltetra(oxypropylene) phosphoric acid, monostearyl tri(oxypropylene) phosphoric acid, monopalmityl(cetyl)tetra(oxypropylene) phosphoric acid,
monopalmityl(cetyl)(oxypropylene)1.5 phos phoric acid monostearyl air sropylenn, phospmi c acid, and monomargaryl (oxypropylene) phosphoric acid, and the sodium, potassium, ammonium, tributylamine and triethanolamine salts thereof.
In addition to the monoalkyloxypropylene phosphoric acid ester, the essential ingredients of the detergent compositions of the invention are a synthetic detergent or surfactant, which can be of the anionic and/or nonionic type, and an aminocarboxylic acid chelating agent. The monoaklyloxypropylene phosphoric acid ester is intended to be used in the presence of a bleaching or oxidizing agent, such as a peroxide bleaching agent, and this is an optional ingredient, but it can be added later, when the washing solution is prepared. In addition to these components, which with the monoalkyloxpropylene phosphoric acid ester are the only essential components, there can be included as optional components builders, fillers, optical whitening agents, coloring agents, perfumes, and other conventional detergent formulation components.
As compared to detergent formulations of this type that do not contain monoalkyloxypropylene phosphoric acid esters, the detergent formulations of the invention have a reduced tendency to corrode copper, zinc and aluminum, and alloys containing such metals. In order to keep the tendency to corrode such metals at-a minimum, the weight ratio of monoalkyl oxypropylene phosphoric acid ester to surfactant should be within the range from about 10:1 to about 1:10.
The detergent compositions of the invention have the following formulation, based on the solids content:
Overall range Preferred range ior zo a 2m 30% Ste 15% Monoalkylpropylene glycol ether phosphoric acid ester Optional ingredients Bleaching or oxidizing agent, such as peroxide Builders, soil suspending agents, and other additives l to 20% 2 to 5% 5 to 40% l5 to 30% IO to 20 to 60% The essential and optional components of the detergent compositions of the invention are solids, for the most part, and consequently the detergent compositions of the invention are conveniently formulated and marketed as solids, in any particulate form, as, for instance, powders, flakes, granules, spray-dried ovoids or spheres, pellets, or other agglomerates. Preferably, the composition is in the form of particles produced by drying an aqueous mixture or slurry of the componcnt. Spray-drying is a preferred drying method, since it produces friable light particles which dissolve rapidly and completely in water. Other drying methods include suspension-drying and drum drying, the latter procedure being particularly useful in the production of particulate detergent mixtures in flake or large particle form.
The detergent composition can also be formulated as an aqueous concentrate which forms a washing solution upon dilution with water. The concentrate has as high a composition solids content as possible, within the range from 20 to 75 percent, preferably from 30 to 60 percent by weight. The upper limit of solids content is normally determined by the solubility of the components in water or other solvent or suspending medium, such as ethyl alcohol, or methyl alcohol. However, solubility in water or other solvent can be increased in the concentrate by the addition of solubilizing agents. To some extent, the monoalkyloxypropylene phosphoric acid esters display a solubilizing effect on the other ingredients. This effect can be increased by the addition of other hydrotropic substances, such as sodium xylene sulfonate and sodium toluene sulfonate. Organic solvents can be used, such as ethyl alcohol or methyl alcohol.
The synthetic detergent or surfactant employed in the compositions of the invention can be of the anionic type, of the nonionic type, or the mixed nonionic-anionic type. Mixtures of anionic and nonionic surfactants can also be employed. Among the anionic surfactants which can be employed are the alkyl aryl sulfonates, the alkyl sulfonates, the alpha-olefin sulfonates, the alkyl ether polyglycol sulfates, and the alkyl phenol ether sulfates. These are all known compounds.
Exemplary of the alkyl aryl sulfonates are the alkyl benzene sulfonates, which have the general formula:

The following Examples in the opinion of the inventors represent preferred embodiments of their invention.
EXAMPLES 1 TO 4 TABLE I by Solution Composition weight Concentration 1.6 g]! 0.8 g/l The tendency of each solution to corrode copper metal was determined by the following test.
To 100 ml. portions of this solution there was added 0.4 g./l. of the alkylether phosphoric acid ester shown in Table II.
To each 100 m]. sample, and a control sample without the phosphoric acid ester, there was added 0.5 g. of copper powder, and the solutions boiled for 30 minutes. After removing the copper powder by filtration, the copper content of each sample was determined by means of an atom absorption photometer. The amount of copper dissolved represents the amount of copper removed by corrosion, and is thus a measure of the tendency of the detergent solution to corrode copper.
For comparison, to show the relative effectiveness of an alkyl phosphoric acid ester, (monocetyl ortho phosphate) was added to another 100 cc. sample (control B), and tested in the same way.
The data are given in TAble ll.
The results for Control A, vis-a-vis Examples 1 to 4, in Table II show that the alkyl oxypropylene phosphoric acid esters of Examples 1 to 4 were effective in inhibiting copper corrosion by the sodium ethylenediaminetetraacetic acid and the peroxide bleaching agent. On the other hand, the alkyl phosphoric acid ester, Control B, was virtually ineffective. This demonstrates the importance of the oxypropylene group in the phosphoric acid ester, in corrosion inhibition.
EXAMPLES 5 TO 7 A detergent composition was prepared to the formulation shown in Table III. This was dissolved in water of 15 of hardness to form a solution of the concentration indicated.
To 100 ml. portions of this solution, 0.4 g./l. of the alkyl oxypropylene phosphoric acid esters listed in Table IV was added. Thereafter, the amount of copper dissolved by the detergent solutions were determined, in the test described in Examples l to 4.

The tendency of this solution to corrode zinc metal was then determined, in comparison with a control that did not contain the phosphoric acid ester. The solution was refluxed for 30 minutes with 0.5 g. zinc powder, the undissolved powder was removed by filtration, and the zinc content of the solution was determined by means of an atom absorption photometer.

EXAMPLE 9 A detergent formulation'was prepared, as shown in Table VIII. This composition was dissolved in water of 5 dH, to the solution concentration shown in the Table.
To a 100 ml. portion of this detergent solution was added 0.3 g./l. mono-cetyl oxypropylene phosphoric acid. Then in comparison with a control, the portion was boiled with an aluminum sheet 3 centimeters square for 30 minutes. The alummum content of the solution was then determined, by means of an atom absorption photometer. The results are shown in Table IX.

The detergent compositions prepared according to the invention, as seen from the above Examples, show a very substantial decrease in the corrosion of copper, zinc and aluminum. Copper, aluminum and zinc corrosion is inhibited even when hard water is used in the preparation of the detergent solution. It, furthermore, was proved by test washing that the compositions according to the invention provide very good washing results and that, in addition, the resulting detergents are low foaming, which is important where the detergents are used in automatic washing machines.
