Description

Technical Field

[0001] The present disclosure relates to a solid alkaline metal protector 2-in-1 detergent and rinse aid composition that effectively reduces corrosion and provides metal protection while also improving the drying time of surfaces. A method of making the composition and methods of using the composition are provided. Background Art

[0002] Alkaline detergents are known to provide effective detergency. However, formulations can vary widely in terms of corrosivity, acceptance as consumer-friendly and / or environmentally friendly products, and other detergent properties. Generally speaking, as the alkalinity of these compositions increases, the difficulty of protecting metal surfaces also increases. Therefore, there is a need for detergent compositions that minimize and / or eliminate metal corrosion of articles in systems employing these detergents beyond known corrosion inhibitors (such as silicates, e.g., sodium silicate).

[0003] Silicates are known to precipitate from aqueous solutions at alkaline pH (i.e., pH below 11), which reduces the effectiveness and consumer acceptance of these materials in preventing corrosion of contacted surfaces when used in aqueous cleaning solutions with lower pH. In addition, when silicate-containing compositions or their residues are allowed to dry on surfaces, films or spots are often formed that are visible and very difficult to remove themselves. The presence of these silicon-containing deposits can affect the texture of the surface being cleaned, the appearance of the surface, and the presence of these silicon-containing deposits on cooking or storage surfaces can affect the taste of materials in contact with the cleaned surface. In addition, such silicon-containing deposits may require an acid cleaning step over time to view the deposits and visual residues. It is desirable to eliminate the need for this step when cleaning surfaces.

[0004] There is also a need to provide a 2-in-1 detergent and rinse aid composition that eliminates the need for multiple formulations, multiple steps, and overall product cost and waste.

[0005] It is another object of the present invention to provide a method for employing alkaline detergents having a pH of about 9 to about 12.5 without causing significant corrosion of metal surfaces.

[0006] It is therefore an object of the present disclosure to provide a 2-in-1 alkaline detergent and rinse aid composition with improved metal protection.

[0007] It is another object of the present disclosure to provide a 2-in-1 alkaline detergent and rinse aid composition with improved metal protection that does not deposit film or particulates onto the cleaned surfaces.

[0008] It is another object of the present disclosure to provide a 2-in-1 alkaline detergent and rinse aid composition having the various improvements described herein, which further provides enhanced surface drying and water hardness protection.

[0009] It is another object of the present disclosure to formulate the 2-in-1 alkaline detergent and rinse aid composition as a solid block, including a pressed solid.

[0010] Other objects, embodiments and advantages of the present disclosure will be apparent to those skilled in the art in view of the following disclosure, drawings and appended claims. Summary of the invention

[0011] The advantages of a solid 2-in-1 alkaline detergent and rinse aid composition are effective corrosion inhibition of metal surfaces such as aluminum without the use of silicate raw materials to eliminate film formation or precipitation of particles on the cleaned surfaces, while also providing improved drying time and water hardness protection.

[0012] According to some aspects of the present disclosure, a solid 2-in-1 alkaline detergent and rinse aid composition comprises: an alkali metal carbonate alkalinity source; an acid chelator or a metal protecting combination of a chelator and an acid with at least one water conditioning agent; and at least one nonionic surfactant.

[0100] In some embodiments, the nonionic surfactant of formula (I) according to embodiments E, J and O has a ratio of ethylene oxide (EO) units to propylene oxide (PO) units of 1:10 to 10:1 and an average molecular weight of 500 to 10,000 g / mol.

[0101] In one embodiment, at least one nonionic surfactant of formula (I) has a hydrophile-lipophile balance (HLB) value in the range of 2 to 17.

The HLB value can be calculated according to the method given in Griffin, Journal of the Society of Cosmetic Chemists (J. Soc. Cosmetic Chemists), 5 (1954) 249-256. The Griffith method described in 1954 for nonionic surfactants is as follows: HLB = 20 × Mh / M, where M h is the molecular mass of the hydrophilic part of the molecule; and M is the molecular weight of the entire molecule. Only the EO part of the surfactant is considered to be hydrophilic, and all other parts only contribute to the entire molecule.

[0103] Additional surfactant

[0104] Further additionally useful nonionic surfactants are generally characterized by the presence of organic hydrophobic groups and organic hydrophilic groups, and are typically produced by the condensation of organic aliphatic, alkyl aromatic or polyoxyalkylene hydrophobic compounds with hydrophilic basic oxide moieties, which are generally ethylene oxide or its polyhydration products, polyethylene glycol. In fact, any hydrophobic compound having hydroxyl, carboxyl, amino or amide groups with reactive hydrogen atoms can be condensed with ethylene oxide or its polyhydration adducts or its mixture with alkylene oxides (such as propylene oxide) to form nonionic surfactants. The length of the hydrophilic polyoxyalkylene moiety condensed with any particular hydrophobic compound can be easily adjusted to produce a water-dispersible compound or a water-soluble compound having a desired balance between hydrophilic and hydrophobic properties. Useful nonionic surfactants include:

[0105] Block polyoxypropylene-polyoxyethylene polymeric compounds (1) based on propylene glycol, ethylene glycol, glycerol, trimethylolpropane and ethylenediamine as initiator reactive hydrogen compounds. Examples of polymeric compounds made by sequential propoxylation and ethoxylation of initiators are commercially available from BASF Corp. One class of compounds is a difunctional (two reactive hydrogen) compound formed by condensation of ethylene oxide with a hydrophobic matrix formed by addition of propylene oxide to the two hydroxyl groups of propylene glycol. The molecular weight of the hydrophobic portion is from about 1,000 to about 4,000. Ethylene oxide is then added to sandwich this hydrophobe between the hydrophilic groups, constituting from about 10% to about 80% by weight of the final molecule, controlled by length. Another class of compounds is a tetrafunctional block copolymer derived from sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weight of the propylene oxide subtype ranges from about 500 to about 7,000; and the hydrophile (ethylene oxide) is added to make up about 10% to about 80% by weight of the molecule.

The alkyl group may be represented by, for example, diisobutylene, diamyl, polymerized propylene, isooctyl, nonyl and dinonyl. These surfactants may be polyoxyethylene, polyoxypropylene and polyoxybutylene condensates of alkyl phenols. Examples of commercial compounds of this chemical nature are available on the market under the trade name of Rhone-Poulenc. and manufactured by Union Carbide get.

[0107] The condensation product of one mole of a saturated or unsaturated, straight or branched chain alcohol having from about 6 to about 24 carbon atoms with from about 3 to about 50 moles of ethylene oxide (3). The alcohol portion may consist of a mixture of alcohols in the carbon range described above, or it may consist of an alcohol having a specific number of carbon atoms within this range. The condensation product of one mole of a saturated or unsaturated, straight or branched chain carboxylic acid having from about 8 to about 18 carbon atoms with from about 6 to about 50 moles of ethylene oxide (4). The acid portion may consist of a mixture of acids in the carbon atom range defined above, or it may consist of acids having a specific number of carbon atoms within the range. In addition to the ethoxylated carboxylic acids commonly referred to as polyethylene glycol esters, other alkanoic acid esters formed by reaction with glycerides, glycerol and polyhydroxy (sugar or sorbitan / sorbitol) alcohols also have application in the present invention for specific embodiments, especially indirect food additive applications. All of these ester moieties have one or more reactive hydrogen sites on their molecules that can be further acylated or ethylene oxide (alkoxide) added to control the hydrophilicity of these materials. When adding these fatty esters or acylated carbohydrates to the compositions of the present invention containing amylases and / or lipases, special care must be taken because of potential incompatibility.

[0108] Examples of nonionic low foaming surfactants include:

[0109] The compound from (1) modified by adding ethylene oxide to ethylene glycol to provide a hydrophile of a specified molecular weight, substantially inverse; and, then adding propylene oxide to obtain a hydrophobic block on the exterior (ends) of the molecule. The molecular weight of the hydrophobic portion of the molecule is from about 1,000 to about 3,100, with the intermediate hydrophile constituting from 10% to about 80% by weight of the final molecule. The molecular weight of the hydrophobic portion of the molecule is from about 2,100 to about 6,700, with the intermediate hydrophile constituting from 10% to 80% by weight of the final molecule. Compounds from groups (1), (2), (3) and (4) modified by "capping" or "end-capping" one or more terminal hydroxyl groups (of the multifunctional moiety) to reduce foaming by reaction with: small hydrophobic molecules such as propylene oxide, butylene oxide, benzyl chloride; and short chain fatty acids, alcohols or alkyl halides containing 1 to about 5 carbon atoms; and mixtures thereof.

[0148] Method for preparing solid composition

[0149] The solid composition can be prepared as a cast solid, an extruded solid, a molded solid or a pressed solid. The composition can be prepared by mixing the various components together and applying the desired curing process. The solid composition is preferably a pressed solid.

[0150] Compared to conventional solid block or tablet compositions that may require high pressure in a tablet press, or casting that requires melting of the composition, consuming a significant amount of energy, and / or extrusion that requires expensive equipment and advanced technical knowledge, the use of compressed solids provides a variety of benefits. Compressed solids overcome various limitations of other solid formulations required to prepare solid compositions. In addition, compressed solid compositions retain their shape under conditions where the composition can be stored or disposed of.

[0151] In the solid pressing process, flowable solids such as granular solids or other particulate solids are combined under pressure to form a solid composition. In the solid pressing process, the flowable solid of the composition is placed in a forming part (e.g., a mold or a container). The method may include a flowable solid gently pressed in a forming part to produce a solid cleaning composition. Pressure may be applied by a block machine or a rotary press, etc. Pressure may be applied at about 1 psi to about 3000 psi, about 1 psi to about 2000 psi, about 1 psi to about 1000 psi, about 1 psi to about 500 psi, about 1 psi to about 300 psi, about 5 psi to about 200 psi, or about 10 psi to about 100 psi. In certain embodiments, the method may be used to be as low as or equal to about 1 psi, or greater than or equal to about 2 psi, or greater than or equal to about 5 psi, or greater than or equal to about 10 psi. As used herein, the term "psi" or "pounds per square inch" refers to the actual pressure applied to the pressed flowable solid, and does not refer to the gauge pressure or hydraulic pressure measured at a point in the device being pressed.

[0152] Solid block and cast solid block material can be made by introducing the castable liquid formulation of the composition that hardens into solid block in the container into the container.Preferred container comprises disposable plastic container or water-soluble film container.Other suitable packaging for composition comprises flexible bag, bag, shrink wrap and water-soluble film such as polyvinyl alcohol.In casting process, liquid and solid components are introduced into final mixing system, and continuously mixed, until component forms the substantially homogeneous liquid mixture that wherein component is distributed in whole mass.In an exemplary embodiment, component is mixed in mixing system for at least about 60 seconds.Once mixing is completed, product is transferred to the packaging container that solidifies.In an exemplary embodiment, casting composition begins to harden into solid form between about 1 minute and about 3 hours.Specifically, casting composition begins to harden into solid form between about 1 minute and about 2 hours.More specifically, casting composition begins to harden into solid form between about 1 minute and about 20 minutes.

[0153] In other respects, solid composite can be formed using batch or continuous mixing system to mix ingredients.In an exemplary embodiment, single-or twin screw extruder is used to combine and mix one or more components to form homogeneous mixture under high shear.In some embodiments, processing temperature is at or below the melting temperature of component.Can distribute the processed mixture from mixer by shaping, casting or other suitable means, thus cleaning compositions hardens into solid form.According to methods known in the art, the structure of substrate can be characterized according to hardness, melting point, material distribution, crystal structure and other similar characteristics of substrate.In general, the solid composite processed according to these methods is substantially homogeneous and dimensionally stable in terms of the component distribution in its whole mass.

[0154] In the extrusion process, liquid and solid components are introduced into the final mixing system, and continuously mixed until the component forms a substantially homogeneous semi-solid mixture in which the component is distributed in the whole mass. The mixture is then discharged from the mixing system and enters or passes through a mold or other forming device. The product is then packaged. In an exemplary embodiment, the shaped composition begins to harden into a solid form between about 1 minute and about 3 hours. Specifically, the shaped composition begins to harden into a solid form between about 1 minute and about 2 hours. More specifically, the formed composition begins to harden into a solid form between about 1 minute and about 20 minutes.

[0155] Method can optionally include a curing step to produce a solid composition. As mentioned herein, the uncured composition comprising a flowable solid is compressed to provide sufficient surface contact between the particles constituting the flowable solid so that the uncured composition will solidify into a stable solid composition. A sufficient amount of particles (e.g., granules) in contact with each other combine the particles for effectively preparing a stable solid composition. A curing step can be included to allow the pressed solid to solidify for a period of time, such as several hours or about 1 day (or longer).

[0156] How to use

[0157] The use methods using solid alkali metal protectant 2-in-1 detergent and rinse aid compositions are particularly useful for household or institutional warewashing. Advantageously, the method of first contacting the use solution of the composition with the hard metal surface to be cleaned and dried and then rinsing the hard metal surface provides both effective cleaning, rinsing and drying of the surface and water hardness protection of the surface without film formation on the metal surface. These methods overcome the limitations of silicates or silicone-containing materials that leave a detrimental white film or residue on the treated metal surface.

[0158] Solid alkali metal protectant 2-in-1 detergent and rinse aid composition is particularly suitable for treating hard metal surfaces including alkaline sensitive metal surfaces (such as aluminum). Advantageously, the method provides metal protection for the use of alkaline cleaning and rinsing compositions without leaving a white film or residue on the treated metal surface. Therefore, the method of use eliminates the need for occasional acid rinsing steps to remove the film or residue that accumulates over time on the treated metal surface. These benefits are achieved while providing cleaning and rinsing / drying performance that is at least substantially similar to that of a silicated composition or a two-part composition.

[0159] Exemplary disclosures of warewashing applications are described in U.S. Patents 8,758,520, 9,139,800 and 10,905,305. The method can be carried out in any household or institutional dishwasher, including, for example, those described in U.S. Patent 8,092,613, which contain all drawings and accompanying drawings incorporated herein by reference in their entirety. Some non-limiting examples of dishwashers include door-type machines or hood-type machines, channel-type machines, under-counter machines, glass washers, long dragon-type machines, cooking utensil machines, utensil washers and household dishwashers. Dishwashers can be single-trough machines or multi-trough machines.

[0160] A door-type dishwasher, also known as a hood-type dishwasher, refers to a commercial dishwasher in which dirty dishes are placed on racks, which are then moved into the dishwasher. Door-type dishwashers clean one or two racks at a time. In this type of dishwasher, the racks are fixed, and the wash and rinse arms move. Door-type machines include two sets of arms, a wash arm and rinse arm, or a single rinse arm.

[0161] Door machines can be either high temperature machines or low temperature machines. In high temperature machines, hot water is used to sterilize the dishes. In low temperature machines, chemical sterilizers are used to sterilize the dishes. Door machines can be either recirculating machines or dump and fill machines. In recirculating machines, the detergent solution is reused or "recirculated" between wash cycles. The concentration of the detergent solution is adjusted between wash cycles to maintain adequate concentration. In dump and fill machines, the detergent solution is not reused between wash cycles. New detergent solution is added before the next wash cycle.

[0162] In addition, the method of use of the solid alkali metal protector 2-in-1 detergent and rinse aid composition is also suitable for use in CIP and / or COP processes to replace the use of bulk detergents that leave hard water residues on the treated surfaces. The method of use may be desirable in other applications where industry standards focus on the quality of the treated surfaces, such that the protection against corrosion, film and hard water scale accumulation provided by the detergent composition and even the 2-in-1 composition is desired.

[0163] Other examples of applications for the use of the solid alkali metal protector 2-in-1 detergent and rinse aid composition include, for example, applications for cleaning and rinsing various metal surfaces, grill and oven cleaners, dishwashing detergents, laundry detergents and rinse aids, other metal hard surface cleaners, and the like. In various of these applications, cleaning compositions with very high alkalinity are most desirable and effective, however damage caused by metal corrosion is undesirable. In addition, effective drying of the surface is desired.

[0164] In the embodiment using solid alkali metal protectant 2-in-1 detergent and rinse aid composition, before use or when using, make solid and aqueous source, preferably water contact, or can be mixed with aqueous source, preferably water.In some embodiments that adopt solid composition, water source contacts with composition to convert solid composition (or a part of multi-purpose solid composition) into use solution.Also can utilize additional dispensing system, it is more suitable for converting replacement solid composition into use solution.Method of the present invention comprises using various solid detergent compositions, comprises the packaging of for example block or " capsule " type.

[0165] In one embodiment, the solid composition is contained in a distributor, to provide a use diluent to a dishwasher (or other point of use). In one embodiment, the distributor can be used to spray water (e.g., in a spray pattern from a nozzle) to form a use solution. For example, water can be sprayed toward equipment or other holding reservoirs together with the solid composition, wherein water reacts with the solid composition to form a use solution. In certain embodiments of the method, the use solution can be configured to drip downward due to gravity until the dissolved solution of the composition is distributed for use. On the one hand, the use solution can be distributed in the washing solution of the dishwasher.

[0166] The solid composition or its use solution can contact the surface or article by a variety of methods for applying the composition, such as spraying the composition, immersing the object in the composition, or a combination thereof. The concentrated or use concentration composition can be applied to the article or contacted with the article by any conventional method or equipment for applying cleaning compositions to objects. For example, the article can be wiped, sprayed with the composition or a use solution made from the composition, and / or the article can be immersed in the composition or a use solution made from the composition. The composition can be sprayed or wiped onto the surface; the composition can be flowed over the surface, or the surface can be immersed in the composition. Contact can be manual or by machine. A preferred embodiment contacts the use solution of the solid composition in a dishwashing machine.

[0167] In embodiments, the use solution of the solid composition applied to the surface in need of treatment may include at least about 100 ppm, at least about 200 ppm, at least about 250 ppm, at least about 300 ppm, and preferably at least about 350 ppm to about 1000 ppm. In other embodiments, the use solution of the solid composition applied to the surface in need of treatment may include about 350 ppm to about 3000 ppm, about 350 ppm to about 2000 ppm, about 350 ppm to about 1500 ppm, or about 350 ppm to about 1000 ppm to advantageously provide detergency and rinsing while protecting the treated metal surface.

[0168] Exemplary articles treated with compositions disclosed herein include utensils in the warewashing industry, such as metal utensils, plastics, tableware, cups, glasses, flatware and cookware. For purposes of the present invention, the terms "tableware" and "ware" are used in the broadest sense to refer to various types of articles for food preparation, service, use and disposal, including basins, pans, trays, kettles, bowls, plates, saucers, cups, glasses, forks, knives, spoons, spatulas and other glass, metal, ceramic, plastic composite articles that can be generally used in public institutions or family kitchens or restaurants. In general, these types of articles can be referred to as food or beverage contact articles because they have surfaces for contacting food and / or beverages. When used in these warewashing applications, solid polymer surfactant systems provide effective flakes, low foaming and fast drying. In some aspects, solid compositions help to dry articles or surfaces (e.g., utensils) within about 30 seconds to a few minutes, or within about 30 seconds to about 90 seconds after applying an aqueous use solution.

[0169] In addition to having the desirable attributes described above for metal protection without leaving a residue or film on surfaces, it may also be useful for the solid composition to be biodegradable, environmentally friendly, and substantially non-toxic.In some embodiments, the components comprising the rinse aid surfactant system may be "food grade".

[0170] Example

[0171] Embodiments of the present disclosure are further defined in the following non-limiting examples. It should be understood that although these embodiments illustrate certain embodiments of the present disclosure, they are provided for illustration only. According to the above discussion and these embodiments, those skilled in the art can determine the basic characteristics of the present disclosure, and without departing from its spirit and scope, various changes and modifications can be made to the embodiments of the present disclosure to make them suitable for various purposes and conditions. Therefore, in addition to those shown and described herein, those skilled in the art will understand the various modifications of the embodiments of the present disclosure according to the foregoing description. Such modifications are also intended to fall within the scope of the appended claims.

[0172] In the following examples, exemplary formulations according to the present application were prepared as described in Table 3 below.

[0173]

[0174] Example 1: Metal corrosion test

[0175] Exemplary formulations were prepared to evaluate the corrosion of silicated formulations versus non-silicated formulations to aluminum. This procedure has been developed in accordance with the National Association of Corrosion Engineers TM-01-69.

[0176] Aluminum test strips (A11100, North American aluminum alloy standard; and A11050P, Japanese aluminum alloy standard) were placed in 4oz glass bottles containing concentrated liquid formulations. The aluminum strips were weighed, labeled, placed in bottles, and placed in a 130°F water bath for eight hours. The aluminum strips were then cleaned by immersion in 70% HNO3 for 3 minutes and rinsed thoroughly with distilled water. The aluminum strips were then weighed and the weight loss was calculated by comparison with the control aluminum strips. The corrosion rate expressed in mils / year was calculated using a standard formula that equates weight loss, time, surface area, and metal density. Corrosion rates exceeding 250MPY are classified as corrosive to metals.

[0177] The exemplary compositions described in Table 3 were analyzed and compared to a non-silicated, commercially available control formulation ("Control") and water as shown in Table 4.

[0178] Table 4

[0179]

[0180] Comparisons of formulations P6, P10, P12 and P13 to the control and water are shown in the accompanying figures. The remaining exemplary formulations in Table 3 did provide performance below the 250 MPY threshold and are therefore not shown in the accompanying figures. Figures 1A to 1C These formulations were compared at increasing concentrations (0 ppm to 3000 ppm), increasing carbonate concentrations (0 ppm to 2500 ppm), and increasing pH (7 to 11).

[0181] The corrosion graph shows a 250 MPY threshold indicator line to easily compare the results of the formulations. Two additional comparative MPY threshold indicator lines at 67 MPY and 20 MPY are included in the scatter plot figure. The 67 MPY threshold is compared to a commercially available non-silicated control, and the 20 MPY threshold is compared to a commercially available silicated metal safe corrosion product.

[0182] Figure 1A Scatter plots are shown for corrosivity (MPY) of water, control formulation, P6, P10, P12, and P13 formulations at 7 pH to 11 pH. The figure shows that the exemplary formulations perform substantially below the 250 MPY limit in alkaline solutions.

[0183] Figure 1B A scatter plot of the corrosivity (MPY) of water, control formulation, P6, P10, P12 and P13 formulations based on carbonate concentration is shown. Again, this figure shows that the exemplary formulation remains below the 250 MPY limit and remains below the entire concentration range when used for A11100.

[0184] Figure 1C A scatter plot of corrosivity (MPY) for water, a control formulation, P6, P10, P12, and P13 formulations based on formulation concentration is shown. The figure shows that all formulations are below the 250 MPY limit when at 1000 ppm or less. However, the figure also shows that formulations P10, P12, and P13 remain below the limit at higher concentrations when used in A11100.

[0185] Example 2: Solid Block Wicking Test

[0186] Exemplary formulations were prepared to evaluate the overall stability of the block form. Formulations P6 to P10, P12 and P13 were compared based on the performance seen in Example 1. Formulations P6 to P9 contained MGDA instead of acid EDTA, formulation P10 contained 6% acid EDTA, P12 contained 12% acid EDTA, and P13 contained 16% acid EDTA, as described in Table 5. All formulation blocks were immersed in water for 3 minutes at a water temperature of about 110°F to 120°F. Approximately 1 inch of solid blocks were immersed in water. The formulation blocks were then air-dried for 3 days and the changes in the structural blocks were measured. The length and width of the blocks were measured before being immersed in water, and then measured again after air drying for 3 days. The difference in swelling was measured (based on block swelling). The lower the swelling, the better the block integrity.

[0187] Figure 2A The percentage change in length of the formulation block is shown, and Figure 2B The percentage variation in width of the formulation blocks is shown.

[0188] like FIG. 2A to FIG. 2B As shown in Figure 1, when the formulation is non-silicated, adding acid EDTA to the formulation significantly improves the block swelling percentage measured by the wicking test. Non-silicated formulations P6 to P9, which contain MGDA instead of acid EDTA in P10, P12, and P13, show the greatest swelling and fragmentation of the solid block. This shows that when the formulation does not include a silicone-containing material (such as silicates commonly used for metal protection), adding acid EDTA improves the stability and cohesion of the solid formulation.

[0189] Solid formulations that do not break apart, such as the exemplary formulations with acid EDTA, are ideal for preventing blockage or accumulation in washing machine dispensers or drainage systems. The term "blockage" and its variants related to the use of solid compositions in dispensers or other drainage systems refer to solids or solid aggregates that have formed in the dispenser and can reduce or prevent the solids from being distributed, i.e., introduced into the use device, such as a dishwasher. Typically, concentrated compositions accumulate in the dispenser until they overflow, while the machine continues to operate without the composition (e.g., detergent). This can be caused by many factors, including but not limited to the precipitation of certain chemicals in the presence of hard water. According to embodiments described herein, formulations with acid EDTA (or another low solubility acid) can overcome this limitation.

[0190] Example 3: Cleaning performance test

[0191] In this example, two exemplary formulations described in Table 3 were compared to the same non-silicated commercially available control formulation described in Table 4 ("Control") and water in a wash test. Exemplary formulations P6 and P10 were tested at a concentration of 500 ppm, while the control was tested at a concentration of 1500 ppm. Test strips were used to determine the cleaning performance of the formulations. These test strips contained blue-dyed protein and fat soils on cards. The strips were then placed in five different spots in the washing machine. The strips were then washed in a wash cycle and the soil removal was compared visually. The test strips with higher soil removal showed the least blue soil residue and therefore demonstrated improved wash performance. The test strips were further analyzed and quantified by determining the soil removal percentage based on the unwashed test strips.

[0192] The soil removal rate was quantified based on a standard image analysis program (Image J, Fiji) that converts the pictures to grayscale (i.e., black indicates soil and white indicates soil removal or cleaning), where the more pixels that change from black to lighter gray or white, the cleaner the test coupon.

[0193] Figure 3The soil removal rates for water, control formulation, formulation P6, formulation P10, and P13 are shown. Formulations P6, P10, and P13 removed approximately 65% ​​to 90% of the soil, while the control formulation removed only 10% to 25% of the soil at three times the concentration. These results clearly show that the exemplary formulations of P6, P10, and P13 provide a significant improvement over the commercial formulations. In the wash cycle, the control formulation at a concentration significantly higher than formulations P6, P10, and P13 performed only slightly better than pure water.

[0194] Example 4: Rinse and Dry Test

[0195] Exemplary formulation P6 as described in Table 3 was compared with a commercial rinse aid formulation as described in Table 5 below in terms of rinsing and drying performance.

[0196] Table 5

[0197]

[0198]

[0199] The two formulations were tested by washing ceramics (ceramics 1 and 2) and melamine and measuring the resulting drying times. The test method consisted of washing the dishes in a door-type dishwasher with 65°C water, 43 seconds wash and 82°C water for 11 seconds rinse as one cycle. The chemicals were metered automatically by a dispenser with a concentration sensor. For each type of dish, 4 dishes were washed simultaneously and the drying time was recorded visually by a stopwatch. The drying time for one cycle was recorded as the average of the 4 dishes. Data for at least 8 cycles were collected and their average would be the drying time for that condition. Figure 4A and Figure 4B Drying times for ceramic and melamine after washing with an exemplary formulation and a commercial formulation are shown in FIG.

[0200] Figure 4A Drying times from 450 ppm to 1000 ppm on ceramic and melamine are shown for Formulation P6. Figure 4B Shown are drying times for a commercial rinse aid formulation at 500 ppm on ceramic and melamine.

[0201] As shown in these figures, the formulations performed similarly. It is generally known that melamine has a longer average drying time than ceramic or other washed dishes. However, the exemplary formulations were shown to dry dishes similarly to commercial formulations containing silicone without poor performance over the entire concentration range (400 ppm to 1000 ppm).
