Description

  The present invention relates to an industrial 2-in-1 cleaning composition that provides both cleaning and rinsing effects in a single cleaning composition. In particular, both the composition and its method of manufacture and use provide a solid detergent composition that is easy to use without the need to use a separate rinse aid composition. This composition and method effectively provides cleaning and rinsing capabilities, and effectively provides cleaning and rinsing capabilities that allow the use of potable water rinses without the addition of a separate rinse agent. Particularly suitable for use in industrial cleaning using a metal carbonate composition.

  Alkaline detergents are widely used in the cleaning of articles by both consumer and industrial dishwashers. Alkaline detergents are widely used due to their ability to remove and emulsify oily, oily and hydrophobic soils. However, alkaline detergents have the disadvantage of requiring rinsing aids to prevent film formation on glass and other substrate surfaces in contact with the alkaline detergent. Film formation is caused in part by using alkaline detergents in combination with certain types of water (including hard water) and water temperature. A solution to hard water film formation is to remove such films using a rinse aid. However, the need for a rinse aid increases the costs associated with alkaline detergents, both due to the preparation of the cleaning composition and the additional costs associated with hot water for the rinse step.

  In addition, rinse aids are used in the rinse cycle after the wash cycle to improve drying time as well as to reduce incomplete parts of the wash (including film removal). Further advantages and methods of using rinse aids are described in US Reissue Pat. No. 38262, which is hereby incorporated by reference in its entirety. The addition of rinse aids to the dishwashing rinse cycle requires the use of GRAS (generally recognized as safe) ingredients, as well as the use of wall space to install both detergent and rinse aid dispensers.

Amphoteric surfactants Amphoteric or ampholytic surfactants contain both basic and acidic hydrophilic groups and organic hydrophobic groups. These ionic materials may be any anionic group or cationic group described herein for other types of surfactants. Basic nitrogen and acidic carboxylate groups are typical functional groups used as basic and acidic hydrophilic groups. In some surfactants, sulfonates, sulfates, phosphonates, or phosphates provide a negative charge.

  Amphoteric surfactants are broadly described as derivatives of aliphatic secondary and tertiary amines, the aliphatic groups of which can be linear or branched, and of aliphatic substituents. One contains about 8-18 carbon atoms and one contains an anionic water solubilizing group such as carboxy, sulfo, sulfato, phosphato, or phosphono. Amphoteric surfactants are subdivided into two large classes known in the art and are described in "Surfactant Encyclopedia" Cosmetics & Toiletries, Vol. 104 (2) 69-71 (1989) (this is , Incorporated herein by reference in its entirety). The first class includes acyl / dialkylethylenediamine derivatives (eg, 2-alkylhydroxyethyl imidazoline derivatives) and salts thereof. The second class includes N-alkyl amino acids and their salts. Some amphoteric surfactants are assumed to fall into both classes.

  Amphoteric surfactants can be synthesized by methods known to those skilled in the art. For example, 2-alkylhydroxyethyl imidazoline is synthesized by condensation and ring closure of a long-chain carboxylic acid (or a derivative thereof) and a dialkylethylenediamine. Commercial amphoteric surfactants are derivatized by subsequent hydrolysis and ring opening of the imidazoline ring by alkylation (eg, using chloroacetic acid or ethyl acetate). During alkylation, one or two carboxy-alkyl groups react to form a tertiary amine, and ether linkages using different alkylating agents yield different tertiary amines.

Long chain imidazole derivatives having use in the present invention generally have the following general formula:

  Here, R is an acyclic hydrophobic group containing about 8 to 18 carbon atoms, and M is a cation that neutralizes the charge of the anion (generally sodium). Examples of commercially available excellent imidazoline-derived amphoteric substances that can be used in the composition of the present invention include cocoamphopropionate, cocoamphocarboxy-propionate, cocoamphoglycinate, cocoamphocarboxy-glycinate, cocoamphopropyl-sulfone. Acid salts, and cocoamphocarboxy-propionic acid. Amphocarboxylic acids can be made from fatty imidazolines, where the dicarboxylic acid functionality of the amphodicarboxylic acid is diacetic acid and / or dipropionic acid.

  The carboxymethylated compound (glycinate) described herein above is often referred to as betaine. Betaines are a special class of amphoteric substances described below in the section entitled Zwitterionic Surfactants.

Long chain N- alkyl amino acids, RNH 2 _(wherein, R = C ₈ ~C ₁₈ straight or branched chain alkyl) are readily prepared by reaction of an aliphatic amine and a halogenated carboxylic acid. Alkylation of the primary amino group of amino acids leads to secondary and tertiary amines. Alkyl substituents may have additional amino groups that provide two or more reactive nitrogen centers. Most commercially available N-alkylamine acids are alkyl derivatives of beta-alanine or beta-N (2-carboxyethyl) alanine. Examples of commercially available N-alkyl amino acid ampholytes having use in the present invention include alkyl beta-amino dipropionate, RN (C ₂ H ₄ COOM) ₂ , and RNHC ₂ H ₄ COOM. In certain embodiments, R may be an acyclic hydrophobic group containing about 8 to about 18 carbon atoms, and M is a cation that neutralizes the charge of the anion.

Suitable amphoteric surfactants include those derived from coconut products such as coconut oil or coconut fatty acids. Additional suitable coconut derived surfactants include, as part of their structure, an ethylenediamine component, an alkanolamide component, an amino acid component, such as glycine, or combinations thereof, and about 8-18 (eg, 12) carbon atoms. Of aliphatic substituents. Such a surfactant can also be considered an alkylamphodicarboxylic acid. These amphoteric surfactants are: C ₁₂ -alkyl-C (O) —NH—CH ₂ —CH ₂ —N ⁺ (CH ₂ —CH ₂ CO ₂ Na) ₂ —CH ₂ —CH ₂ —OH, or C ₁₂ - to include an alkyl ^{_{-C (O) -N (H)}} -CH 2 -CH 2 -N + (CH 2 -CO 2 Na) chemical structure represented as 2 _-CH 2 -CH 2 -OH it can.

Containing. Examples of such zwitterionic synthetic surfactants include derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, where the aliphatic group may be linear or branched, and aliphatic substituted One of the groups contains 8 to 18 carbon atoms and one contains an anionic water solubilizing group such as carboxy, sulfonate, sulfate, phosphate, or phosphonate.

The method also includes generating a cleaning solution using an alkaline 2-in-1 detergent composition and water, contacting the cleaning solution to soiled articles in a dishwasher, and another rinse aid composition Rinsing the article with potable water without requiring the use of objects. This rinse is performed only with potable water.

  In another embodiment, the method of the present invention provides the individual components of the 2-in-1 detergent composition separately and mixes the individual components with water in situ to produce the desired wash solution. Generating.

  When practicing the method of the present invention, the 2-in-1 detergent composition described above is inserted into a dishwasher dispenser. The dispenser can be selected from a variety of different dispensers depending on the physical shape of the composition. For example, liquid compositions use syringes or plunger pumps, syringe / plunger injection, gravity feed, siphon supply, aspirators, eg water soluble packets such as polyvinyl alcohol or foil pouches 1 It can be dispensed by batch, discharge from a pressurized chamber, or diffusion through a membrane or permeable surface. If the composition is a gel or a thick liquid, the composition can be used with either a peristaltic pump or a bellows pump to dispense water-soluble packets such as syringe / plunger injections, caulking guns such as polyvinyl alcohol or foil pouches. It can be dispensed by a single dose to be used, by evacuation from a pressurized chamber, or by diffusion through a membrane or permeable surface. Preferably, when the composition is a solid or powder, the composition may be sprayed, flooded, auger, shaker, tablet dispenser, for example a single dose using a water soluble packet such as polyvinyl alcohol or foil pouch, or a membrane or It can be distributed by diffusion through a permeable surface. The dispenser may also be a dual dispenser where one component is dispensed on one side and the other component is dispensed on the other side. These exemplary dispensers are located in or associated with various dishwashers and include counter dishwashers, bar washers, door machines, conveyor machines, or flight machines. The dispenser may be present in the dishwasher, away from the dishwasher or attached outside the dishwasher. A single dispenser can be fed to one or more dishwashers.

  Once the 2-in-1 detergent composition is inserted into the dispenser, a dishwasher wash cycle is initiated and a wash solution is produced. The cleaning solution comprises an alkaline 2-in-1 detergent composition and water from a dishwasher. The water may be any type of water, such as hard water, soft water, clean water, or dirty water. The most preferred washing solution is a preferred pH range of about 7 to about 11.5, more preferably about 9.5 to about 11 as measured by a pH probe based on a solution of the composition in a 16 gallon dishwasher. .5 is maintained. If the probe allows to perform both functions, millivolts can be measured using the same probe by simply switching the probe from pH to millivolt. The dispenser or dishwasher can optionally include a pH probe to measure the pH of the cleaning solution throughout the cleaning cycle. The actual concentration or ratio of water to detergent will depend on the specific surfactant used. Typical concentration ranges include up to 3000 ppm, preferably 1 to 3000 ppm, more preferably 100 to 3000 ppm, and most preferably 300 to 2000 ppm. Again, the concentration actually used depends on the selected surfactant.

  When used according to the method of the present invention, the use solution can have a high temperature (ie, be heated to a high temperature). In one example, a use solution at a temperature of about 120 ° F. to about 185 ° F., about 140 ° F. to about 185 ° F. is contacted with the substrate to be cleaned. In another example, a use solution at a temperature of about 150 ° F. to about 160 ° F. is contacted with the substrate to be cleaned.

  After the cleaning solution is produced, the cleaning solution comes into contact with dirt on the articles in the dishwasher. Examples of soils are those commonly encountered in foods, such as proteinaceous soils, hydrophobic fat soils, starches and sugar-based soils related to carbohydrates and simple sugars, milk and dairy soils, fruits And vegetable stains. Examples of soils also include minerals from hard water, such as potassium, calcium, magnesium, and sodium. Articles to be contacted include articles made of glass, plastic, aluminum, steel, copper, brass, silver, rubber, wood, ceramic, and the like. Articles commonly present in dishwashers such as glass, bowls, plates, cups, pots and pans, heat-resistant products such as cookie sheets, cake pans, muffin pans, silver dishes such as forks, spoons , Knives, cooking utensils such as wooden spoons, spatulas, rubber scrapers, utility knives, tongs, grill cooking utensils, serving utensils and the like. The cleaning solution can come into contact with the soil in several ways, including spraying, dipping, drainage pump fluid, mist, and spraying.

  Once the cleaning solution contacts the soil, the soil is removed from the article. The removal of soil from the article is accomplished by a chemical reaction between the cleaning solution and the soil and the mechanical action of the cleaning solution on the article, depending on the manner in which the cleaning solution contacts the article.

  Once the soil is removed, the article is rinsed with potable water as part of the dishwasher wash cycle without the use of a separate or additional rinse aid composition.

  These methods can include more or fewer steps than described herein. For example, the method can include additional steps typically associated with a dishwasher cleaning cycle. For example, the method can optionally include the use of an acidic detergent. For example, the method can optionally include an acidic detergent alternating with the described alkaline detergent.

Method for Producing Composition The composition of the present invention comprises a liquid product, a concentrated liquid product, a gelled liquid product, a paste, a granulated and pelleted solid composition, a powder, a solid block composition, a cast solid block composition, an extruded solid block Compositions and the like can be included.

  Solid particulate materials can be made by simply blending the dried solid components in the appropriate ratio or by aggregating the material in a suitable agglomeration system. The pelletized material can be produced by compressing solid particulate material or agglomerated material in a suitable pelletizing device to obtain a suitably sized pelletized material. Solid blocks and cast solid block materials can be made by introducing a pre-cured block of material or a castable liquid (cured in the container into a solid block) into the container. Suitable containers include disposable plastic containers or water-soluble film containers. Other suitable packaging for the composition includes water-soluble films such as flexible bags, packets, shrink wrap, and polyvinyl alcohol.

  The solid detergent composition can be formed using a batch or continuous mixing system. In exemplary embodiments, a single or twin screw extruder can be used to combine and mix one or more components at high shear to produce a homogeneous mixture. In some embodiments, the processing temperature is at or below the melting temperature of the component. The treated mixture can be dispensed from the mixer by molding, casting, or other suitable means, where the detergent composition cures to a solid form. The structure of the matrix can be characterized according to methods known in the art according to its hardness, melting point, material distribution, crystal structure, and other similar properties. In general, a solid detergent composition treated according to the method of the present invention is substantially homogeneous and dimensionally stable with respect to component distribution throughout its mass.

  In the extrusion process, the liquid and solid components are introduced into the final mixing system and the components are mixed until the components form a substantially homogeneous semi-solid mixture distributed throughout the mass. This mixture is then discharged from the mixing system into or through a mold or other molding means. Next, the product is packaged. In an exemplary embodiment, the composition formed begins to cure to a solid state in about 1 minute to about 3 hours. In particular, the formed composition begins to cure to a solid state in about 1 minute to about 2 hours. More specifically, the formed composition begins to cure to a solid state in about 1 minute to about 20 minutes.

  In the casting process, liquid and solid components are introduced into the final mixing system and the components are mixed until the components form a substantially homogeneous liquid mixture distributed throughout the mass. In an exemplary embodiment, the ingredients are mixed in a mixing device for at least about 60 seconds. When mixing is complete, the product is transferred to a packaging container where solidification occurs. In an exemplary embodiment, the casting composition begins to cure to a solid state in about 1 minute to about 3 hours. In particular, the casting composition begins to cure to a solid state in about 1 minute to about 2 hours. More specifically, the casting composition begins to cure to a solid state in about 1 minute to about 20 minutes.

  In a compressed solids process, a flowable solid, such as a granular solid containing a binder or other granular solid, such as a hydrated chelator, such as a hydrated aminocarboxylate, a hydrated polycarboxylate, Or hydrated anionic polymer, hydrated citrate, hydrated tartrate, etc. together with alkali metal carbonate) under pressure. In a pressurized solid process, the flowable solid of the composition is placed in a foam (eg, a mold or container). The method can include gently pushing the flowable solid into the foam to produce a solid cleaning composition. The pressure can be applied by a block machine or a turntable press. The pressure can be applied at about 1 to about 2000 psi, about 1 to about 300 psi, about 5 psi to about 200 psi, or about 10 psi to about 100 psi. In some embodiments, the method is greater than or equal to about 1 psi, greater than or equal to about 2, greater than or equal to about 5, or greater than or equal to about 10 psi. Pressure can be used. As used herein, the term “psi” or “pounds per square inch” refers to the actual pressure applied to the fluidized solid to be pressurized, either a gauge measured at a point in the apparatus being pressurized or It does not refer to hydraulic pressure. The method can include a curing step to produce a solid cleaning composition. As referred to herein, an uncured composition comprising a flowable solid is compressed to provide sufficient surface contact between the particles comprising the flowable solid, the uncured composition being a stable solid wash It will solidify into a composition. A sufficient amount of particles (e.g., granules) in contact with each other provides the bonding of the particles to each other, which is effective to produce a stable solid composition. Including a curing step includes allowing the compressed solid to solidify over a period of time, such as several hours, or about a day (or more). In a further embodiment, the method vibrates a flowable solid in a foam or mold, such as the method disclosed in US Pat. No. 8,889,048, which is incorporated herein by reference in its entirety. Could be included.

  The use of compressed solids can be achieved with conventional solid block or tablet compositions that require high pressure in a tablet press, or casting that requires melting of compositions that consume large amounts of energy, and / or expensive equipment and advanced It offers many advantages over extrusion, which requires sophisticated technical know-how. Compressed solids overcome these various limitations of other solid preparations where there is a need to make a solid cleaning composition. Further, the compressed solid composition retains its shape under conditions that allow the composition to be stored or processed.

  The term “solid” means that the cured composition does not flow and substantially retains its shape under moderate stress, pressure or just gravity. The solid may be in various forms such as powders, flakes, granules, pellets, tablets, troches, packs, briquettes, bricks, solid blocks, single doses, or other solid forms known to those skilled in the art. . The hardness of the solid casting composition and / or the pressurized solid composition can range from a relatively dense and hard molten solid product, such as concrete, to a hardness characterized as a cured paste. . Furthermore, the term “solid” refers to the state of the detergent composition under the expected conditions of storage and use of the solid detergent composition. In general, the detergent composition is expected to remain in solid form when exposed to temperatures up to about 100 ° F., particularly up to about 120 ° F.

  The resulting solid detergent composition is not particularly limited but can take the form of a cast solid product; extruded or molded solid pellets, blocks, tablets, powders, granules, flakes; compressed solids; or molded solids Can then be ground or shaped into powders, granules or flakes. In an exemplary embodiment, the extruded pellet material formed by the solidified matrix has a weight of about 50 g to about 250 g, and the extruded solid formed by the composition has a weight of about 100 g or more, formed by the composition. The resulting solid block detergent has a weight of about 1 to about 10 kg. The solid composition provides a stable source of functional material. In some embodiments, the solid composition can be dissolved, for example, in an aqueous medium or other medium to create a concentrate and / or use solution. This solution can be directed to a storage container for later use and / or dilution or applied directly to the place of use.

Examples 1-4
The materials used in Examples 1-4 are shown here:
Pluronic® 25R2: EO / PO copolymer available from BASF.
Novel® II 1012GB-21: Alcohol alkoxylate available from Sasol.
Additional materials commercially available from multiple sources included: sodium carbonate, ash monohydrate, sodium tripolyphosphate (anhydrous), zinc chloride, HEDP, and KOH.
For Examples 1-4, exemplary 2-in-1 detergents were prepared and shown in Table 2. Throughout Examples 1-4, the formulation is also referred to as Experimental Formula 1 (Experiment 1).

Existing detergents, rinse aids, and experimental formula 1 were tested against distilled water. Detergent Control 1 and Control 2 were commercially available surfactants (phosphate surfactants). Rinse Aid Control 1 and Rinse Aid Control 2 are two commercially available rinse aids (using higher amounts of active ingredient surfactants of at least two ionic categories (eg, nonionic and cationic)) there were. The working concentrations for all experiments described below are provided in the table below.

  All dishwashing tests were performed on a Hobart AM-15 dishwasher using 10 oz. Libbey glass. The specifications of the Hobart AM-15 dishwasher are as follows:

Example 1
Dynamic surface tension
SITA Science line t60 measures the dynamic surface tension of liquids up to a semi-static range. Bubbles are generated from capillaries of known radius. Bubble pressure is measured as a function of bubble lifetime, which can be correlated with surface tension according to the Young-Laplace equation. Dynamic surface tension provides a perspective on the dynamic behavior of surfactants and other surfactant compounds under dynamic conditions, i.e., how fast the surfactant can reach the surface. Dynamic surface tension is a function of surfactant concentration, temperature, and type. The dynamic surface tension behavior of surfactants is particularly important in applications where a quick response of the surfactant is required, for example in a short rinse cycle of an automatic dishwasher.

Equipment and materials:
1. SITA T60 (Sita Messtechnik, Germany)
2. 2. Oil bath with stir bar 3. Heating and stirring plate 4. Glass beaker Glass vial (20 ml)

SITA Science line t60 was calibrated with DI water. A clean water sample after calibration should have a surface tension of 72.0 ± 1.0 mN / m (depending on water quality and temperature). After calibration, SITA was programmed and read at the desired time intervals (ie, 0.3, 1.6, 3.0, and 9.1 seconds). For each composition to be tested (denoted as Samples AC) (eg, three samples from Experiment 1, three samples from Detergent Control 1), three separate solutions of the desired ppm were prepared. 10-15 ml was transferred to a 20 ml vial and immersed in an oil bath heated to 72 ° C. (160 ° F.) ± 2 ° C. Samples were equilibrated for 10-15 minutes. Samples were individually removed from the oil bath and tested with SITA. After testing each sample, a SITA cleaning operation was performed, and then the surface tension of DI water was checked to confirm that the SITA was sufficiently clean. When the measured value of DI water was not within 72.0 ± 1.0 mN / m, the washing operation was performed again. Experimental data of surface tension (mN / m) vs. bubble life at 160 ° F. are shown in Tables 4A-4F below, where τ is the bubble life (S) and γ is the surface tension (mN / m ).

The average surface tension at 160 ° F. was tested for average bubble lifetimes of 0.3, 1.6, 3.0, and 9.1 seconds. The results are shown in Table 5.

  The data shows that the surface tension of Experimental Formula 1 rapidly decreases due to the significant decrease in surface tension at a bubble life of 9.1 seconds. This is similar to a good rinse aid such as the rinse aid control 2. These results are shown in FIG.

Example 2
100-cycle membrane evaluation of commercial dishwashing detergents To investigate the ability of various detergent compositions to remove stains and membranes from tableware, six films were removed by removing all membranes and foreign objects from the glass surface. A Libbey 10 oz glass tumbler was prepared. The Hobart AM-15 dishwasher was then filled with an appropriate amount of water and the water hardness was examined. After recording the hardness value, the tank heater was turned on. On the day of the experiment, the water hardness was 17 grains. The dishwasher was turned on and a dishwasher wash / rinse cycle was performed until a wash temperature of about 150 ° F. to about 160 ° F. and a rinse temperature of about 175 ° F. to about 190 ° F. were reached. Next, the controller was set and an appropriate amount of detergent was placed in the wash tank. The detergent was added so that the detergent concentration in the working solution was 750 parts per million (ppm) when mixed with water during the cycle to form a working solution. The solution in the washing tank was titrated to check the detergent concentration. The dishwasher had a wash bath capacity of 58 liters, a rinse capacity of 2.8 liters, a wash time of 50 seconds, and a rinse time of 9 seconds.

  6 clean glass tumblers placed diagonally in the Raburn rack, 4 Newport 10 ounce plastic tumblers placed off the diagonal in the Raburn rack (see figure below for placement), and the dishwashed rack Inside the machine (P = plastic tumbler; G = glass tumbler).

  Next, a 100 cycle test was started. At the beginning of each wash cycle, the appropriate amount of detergent was automatically placed in the dishwasher to maintain the initial detergent concentration. The detergent concentration was controlled by electrical conductivity.

After the end of 100 cycles, the rack was removed from the dishwasher and the glass and plastic tumblers were dried. The glass and plastic tumblers were then graded for stain and film accumulation using film ratings and analytical light box evaluation. The score scale of the membrane is shown in Table 6.

  The light box test used a digital camera, light box, light source, light meter, and control computer using “Spot Advance” and “Image Pro Plus” commercial software. The glass to be evaluated was placed sideways on a light box, and the intensity of the light source was adjusted to a predetermined value using an exposure meter. A photographic image of the glass was taken and stored on a computer. The software was then used to analyze the upper half of the glass and the computer showed a histogram where the area under the graph was proportional to the film thickness.

  In general, a small light box score indicates that more light could pass through the tumbler. That is, the smaller the light box score, the more effective the composition prevented scale formation on the tumbler surface. A clean unused glass tumbler has a light box score of approximately 12,000, which corresponds to a score of 72,000 for 6 glass tumblers, and a clean unused plastic tumbler is approximately 25 , 500 light box scores, which corresponds to a light box score of about 102,000 for four plastic tumblers. The minimum resulting light box score (ie, a total of 6 clean glass tumblers and 4 clean plastic tumblers) is about 174,000. In general, if the sum of 6 clean glass tumblers and 4 clean plastic tumblers is about 360,000 or less, the detergent composition is considered effective in controlling hard water scale formation. It is done.

The results of 100 cycles of testing are shown in Tables 7-8 and give the average film rating for glass and plastic tumblers.

Example 3
50 Cycle Redeposition Experiment of Commercial Dishwashing Detergent The cleaning effectiveness of the compositions and controls according to the present invention was further evaluated using a 50 cycle redeposition experiment of commercial dishwashing detergent. To test the composition's ability to clean glass and plastic, six 10 ounce Libbey refractory glass tumblers and one plastic tumbler were used. The glass tumbler was cleaned before use. A new plastic tumbler was used in each experiment.

  A food soil solution was prepared using a 50/50 combination of beef stew and hot point soil and used at 2000 ppm soil. The soil included 2 cans of Dinty Moore Beef Stew (1360 g), a large can of tomato sauce (822 g), 15.5 sticks of Blue Bonnet Margarine (1746 g), and powdered milk (436.4 g). Hot point soil was added to the machine to maintain a sump concentration of about 2000 ppm.

  After the dishwasher was filled with 17 grains of water, the heater was turned on. The washing temperature was adjusted to about 150-160 ° F. The final rinse temperature was adjusted to about 175-190 ° F. The controller was set to display the amount of detergent in the wash tank. Glass and plastic tumblers were placed in a Raburn rack (see below for placement; P = plastic tumbler, G = glass tumbler), and the rack was placed in a dishwasher.

  Next, the dishwasher was started and operated in an automatic cycle. At the beginning of each cycle, an appropriate amount of hot point soil was added to maintain a 2000 ppm sump concentration. The concentration of the detergent was controlled by the conductivity.

  When the 50 cycles were complete, the glass was allowed to dry overnight. The glass was then graded for stain and film accumulation (visual).

  Coomassie brilliant blue R staining was then used followed by decolorization with an acetic acid / methanol solution to grade glass and plastic tumblers for protein accumulation. Coomassie Brilliant Blue R stain was prepared by combining 1.25 g of Coomassie Brilliant Blue R dye in distilled water with 45 ml of acetic acid and 455 ml of 50% methanol. The decolorization solution consisted of 45% methanol in distilled water and 10% acetic acid.

  The amount of protein remaining on the glass and plastic tumblers after decolorization was visually assessed on a scale of 1-5. A score of 1 indicated that no protein was present after decolorization-no stain / no membrane. A rating of 2 indicated that random spots were covered with protein (barely discernable) after decolorization-random stain (or about 20% of the surface was covered with a membrane). A rating of 3 indicated that about one quarter of the surface was covered with protein after decolorization (ie, about 40% of the surface was covered with a membrane). A score of 4 indicated that about half of the glass / plastic surface was covered with protein after decolorization (ie, about 60% of the surface was covered with a membrane). A rating of 5 indicated that after decolorization, the entire surface was covered with protein (ie, at least about 80% of the surface was covered with a membrane).

  Average glass tumbler scores tested for soil removal to determine the average soil removal score from the glass surface and average plastic tumbler scores tested for soil removal to average the soil removal score from the plastic surface. It was determined. Similarly, the average redeposition score of the glass surface determined by averaging the scores of the glass tumblers tested for redepositionability, and the average redeposition of the plastic surface by averaging the scores of the plastic tumblers tested for redepositionability A score was determined.

The results are shown in the following table, which shows that the detergent composition according to the present invention provides at least a substantially similar cleaning effect and, in various embodiments, an effect superior to the commercial product. The rating scale is shown in Table 9.

The results of the 50 cycle test are shown in Tables 10-11.

Example 4
7-cycle stain, membrane, and soil removal assessment of commercial dishwashing detergent or rinse aid To test the composition's ability to clean glass and plastic, 4 x 10 ounce Libbey heat-resistant glass tumblers Newport plastic tumbler was used. The glass tumbler was cleaned before use.

  A food soil solution was prepared using a 50/50 combination of beef stew and hot point soil. The concentration of this solution was about 2000 ppm. The soil included 2 cans of Dinty Moore Beef Stew (1360 g), a large can of tomato sauce (822 g), 15.5 sticks of Blue Bonnet Margarine (1746 g), and powdered milk (436.4 g).

  The dishwasher was then filled with an appropriate amount of water. After filling the dishwasher with water, the heater was turned on. The final rinse temperature was adjusted to about 180 ° F. Glass and plastic tumblers were soiled by rotating the glass three times in a 1: 1 (volume) mixture of Campbell's Cream of Chicken Soup: Kemp's Whole Milk. The glass was then placed in an oven at about 160 ° F. for 8 minutes. While the glass was drying, about 120 g of food soil solution (which corresponds to about 2000 ppm food soil in the pump) was placed in the dishwasher.

  Dirty glass and plastic tumblers were placed in a Raburn rack (see below for placement; P = plastic tumbler, G = glass tumbler), and the rack was placed in a dishwasher. The first two rows of tumblers were tested for soil removal and the second two rows of tumblers were tested for redeposition.

  Next, the dishwasher was started and operated in an automatic cycle. After the automatic cycle, the upper part of the glass tumbler and plastic tumbler was wiped with a dry towel. The glass and plastic tumblers being tested for soil removal were removed and the soup / milk soiling procedure was repeated. Redeposited glass and plastic tumblers were not removed.

  Appropriate amounts of detergent and food soil were added to the wash tank at the beginning of each cycle to replace the rinse dilution. The soiling and washing steps were repeated 7 cycles.

  Coomassie brilliant blue R staining was then used followed by decolorization with an acetic acid / methanol solution to grade glass and plastic tumblers for protein accumulation. Coomassie brilliant blue R staining solution was prepared by combining about 1.25 g of Coomassie brilliant blue R dye with about 45 ml of acetic acid and about 455 ml of 50% methanol. The decolorization solution consisted of 45% methanol in distilled water and 10% acetic acid. The amount of protein remaining on the glass and plastic tumblers after decolorization was visually assessed on a scale of 1-5. A score of 1 indicated that no protein was present after decolorization. A rating of 2 indicated that random spots were covered with protein (barely discernable) after decolorization. A rating of 3 indicated that about a quarter of the surface was covered with protein after decolorization. A rating of 4 indicated that about half of the glass / plastic surface was covered with protein after decolorization. A rating of 5 indicated that the entire surface was covered with protein after decolorization.

  Average glass tumbler scores tested for protein removal to determine the average protein removal score from the glass surface, average plastic tumbler scores tested for protein removal, and average protein removal score from the plastic surface It was determined. Similarly, the average of the glass tumblers tested for redeposition was averaged to determine the average protein redeposition score for the glass surface, the average of the plastic tumblers tested for protein redeposition was averaged, and the average of the plastic surface A protein redeposition score was determined.

Glass was visually evaluated in the glass viewing area against a black background. Each set of glass was evaluated as a set, ie, all redeposited glasses were evaluated for all products tested. For each set, an overall average can be determined. Table 12 shows the evaluation scale used.

The results of the 7-cycle test are given in Tables 13-14 and show the average stain, membrane, and protein staining scores (with standard deviation) for glass and plastic tumblers.

After calibration, SITA was programmed and read at the desired time intervals (ie, 0.3, 1.6, 3.0, and 9.1 seconds). For each composition to be tested (denoted AC), three separate solutions of the desired ppm (eg, three samples from Experiment 2, three samples from Detergent Control 1) were prepared. 10-15 ml was transferred to a 20 ml vial and immersed in an oil bath heated to 72 ° C. (160 ° F.) ± 2 ° C. Samples were equilibrated for 10-15 minutes. Samples were individually removed from the oil bath and tested with SITA. After each sample was tested, SITA was washed and then the surface tension of DI water was checked to confirm that SITA was sufficiently clean. When the measured value of DI water was not within 72.0 ± 1.0 mN / m, the washing operation was performed again. Experimental data of surface tension (mN / m) vs. bubble life at 160 ° F. are shown in Tables 17A-17F below, where τ is the bubble life (seconds) and γ is the surface tension (mN / m ).

Average surface tension at 160 ° F. was tested for average bubble lifetimes of 0.3, 1.6, 3.0, and 9.1 seconds. The results are shown in Table 18.

  The data show that the surface tension of Experimental Formula 2 decreases rapidly due to a significant decrease in surface tension at a bubble life of 9.1 seconds. This is similar to a good rinse aid such as the rinse aid control 2. These results are shown in FIG.

Example 6
100-cycle membrane evaluation of commercial dishwashing detergents To investigate the ability of various detergent compositions to remove stains and membranes from tableware, six films were removed by removing all membranes and foreign objects from the glass surface. A Libbey 10 oz glass tumbler was prepared. The Hobart AM-15 dishwasher was then filled with an appropriate amount of water and the water hardness was examined. After recording the hardness value, the tank heater was turned on. On the day of the experiment, the water hardness was 17 grains. The dishwasher was turned on and a dishwasher wash / rinse cycle was performed until a wash temperature of about 150 ° F. to about 160 ° F. and a rinse temperature of about 175 ° F. to about 190 ° F. were reached. Next, the controller was set and an appropriate amount of detergent was placed in the wash tank. The detergent was added so that the detergent concentration in the working solution was 750 parts per million (ppm) when mixed with water during the cycle to form a working solution. The solution in the washing tank was titrated to check the detergent concentration. The dishwasher had a wash bath capacity of 58 liters, a rinse capacity of 2.8 liters, a wash time of 50 seconds, and a rinse time of 9 seconds.

  6 clean glass tumblers placed diagonally in the Raburn rack, 4 Newport 10 ounce plastic tumblers placed off the diagonal in the Raburn rack (see figure below for placement), and the rack is dishwashed Inside the machine (P = plastic tumbler; G = glass tumbler).

  Next, a 100 cycle test was started. At the beginning of each wash cycle, the appropriate amount of detergent was automatically placed in the dishwasher to maintain the initial detergent concentration. The detergent concentration was controlled by electrical conductivity.

  Next, a 100 cycle test was started. At the beginning of each wash cycle, the appropriate amount of detergent was automatically placed in the dishwasher to maintain the initial detergent concentration. The detergent concentration was controlled by electrical conductivity.

After the end of 100 cycles, the rack was removed from the dishwasher and the glass and plastic tumblers were dried. The glass and plastic tumblers were then graded for stain and film accumulation using film ratings and analytical light box evaluation. The score scale of the membrane is shown in Table 19.

  The light box test used a digital camera, light box, light source, light meter, and control computer using “Spot Advance” and “Image Pro Plus” commercial software. The glass to be evaluated was placed sideways on a light box, and the intensity of the light source was adjusted to a predetermined value using an exposure meter. A photographic image of the glass was taken and stored on a computer. The software was then used to analyze the upper half of the glass, and the computer showed a histogram where the area under the graph was proportional to the thickness of the membrane.

  In general, a small light box score indicates that more light can pass through the tumbler. That is, the smaller the light box score, the more effective the composition prevented scale formation on the tumbler surface. A clean unused glass tumbler has a light box score of approximately 12,000, which corresponds to a score of 72,000 for 6 glass tumblers, and a clean unused plastic tumbler is approximately 25 , 500 light box scores, which corresponds to a light box score of about 102,000 for four plastic tumblers. The minimum resulting light box score (ie, a total of 6 clean glass tumblers and 4 clean plastic tumblers) is about 174,000. Generally, if the sum of 6 clean glass tumblers and 4 plastic tumblers is about 360,000 or less, the detergent composition is considered effective in controlling hard water scale formation. .

The results of 100 cycles of the test are shown in Tables 20 and 21.

Example 7
50 Cycle Redeposition Experiment of Commercial Dishwashing Detergent The cleaning effect of the composition according to the present invention and the control was further evaluated using a 50 cycle redeposition experiment of commercial dishwashing detergent.

A new plastic tumbler was used in each experiment.

  A food soil solution was prepared using a 50/50 combination of beef stew and hot point soil and used at 2000 ppm soil. The soil included 2 cans of Dinty Moore Beef Stew (1360 g), a large can of tomato sauce (822 g), 15.5 sticks of Blue Bonnet Margarine (1746 g), and powdered milk (436.4 g). Hot point soil was added to the machine to maintain a soil concentration of about 2000 ppm.

  After the dishwasher was filled with 17 grains of water, the heater was turned on. The washing temperature was adjusted to about 150-160 ° F. The final rinse temperature was adjusted to about 175-190 ° F. The controller was set to display the amount of detergent in the wash tank. Glass and plastic tumblers were placed in a Raburn rack (see below for placement; P = plastic tumbler, G = glass tumbler), and the rack was placed in a dishwasher.

  Next, the dishwasher was started and operated in an automatic cycle. An appropriate amount of hot point sol was added at the beginning of each cycle to maintain a 2000 ppm soil concentration. The concentration of the detergent was controlled by the conductivity.

  When the 50 cycles were complete, the glass was allowed to dry overnight. The glass was then graded for stain and film accumulation (visual).

  Next, Coomassie Brilliant Blue R staining was used and then decolorized with an acetic acid / methanol solution to grade glass and plastic tumblers for protein accumulation. Coomassie Brilliant Blue R stain was prepared by combining 1.25 g of Coomassie Brilliant Blue R dye in distilled water with 45 ml of acetic acid and 455 ml of 50% methanol. The decolorization solution consisted of 45% methanol in distilled water and 10% acetic acid.

  The amount of protein remaining on the glass and plastic tumblers after decolorization was visually assessed on a scale of 1-5. A score of 1 indicated that no protein was present after decolorization-no stain / no membrane. A rating of 2 was a random stain (or about 20% of the surface was covered with a membrane) that indicated that random locations (barely discernable) were covered with protein after decolorization. A rating of 3 indicated that about one quarter of the surface was covered with protein after decolorization (ie, about 40% of the surface was covered with a membrane). A score of 4 indicated that about half of the glass / plastic surface was covered with protein after decolorization (ie, about 60% of the surface was covered with a membrane). A rating of 5 indicates that after decolorization, the entire surface was covered with protein (ie, at least about 80% of the surface was covered with a membrane).

  Average glass tumbler scores tested for soil removal to determine the average soil removal score from the glass surface and average plastic tumbler scores tested for soil removal to average the soil removal score from the plastic surface. It was determined. Similarly, the average redeposition score of the glass surface determined by averaging the scores of the glass tumblers tested for redepositionability, and the average redeposition of the plastic surface by averaging the scores of the plastic tumblers tested for redepositionability A score was determined.
