JP6871452B2 - Detergent composition that performs both cleaning and rinsing functions - Google Patents

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 the method of making and using it, provide an easy-to-use solid detergent composition without the need to use a separate rinse aid composition. This composition and method effectively provides cleaning and rinsing abilities and effectively provides cleaning and rinsing abilities that allow the use of drinking water rinsing without the addition of separate rinsing agents. Especially suitable for use in industrial cleaning where the metal carbonate composition is used.

Alkaline detergents are widely used in the cleaning of articles in both consumer and industrial dishwashers. Alkaline detergents are widely used due to their ability to remove and emulsify greasy, oily and hydrophobic stains. However, alkaline detergents have the disadvantage of requiring a rinse aid to prevent film formation on the glass and other substrate surfaces in contact with the alkaline detergent. Membrane formation is partly caused by the use of alkaline detergents in combination with certain types of water (including hard water) and the temperature of the water. The solution to hard water film formation is to remove such film using a rinse aid. However, the need for rinsing aids 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 rinsing process.

In addition, rinse aids are used in the rinse cycle after the wash cycle to improve drying time and to reduce imperfections in the wash (including removal of the membrane). Further advantages and methods of using rinsing aids are described in US Reissue Patent No. 38262, which is incorporated herein 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 and the use of wall space to install both detergent dispensers and rinse aid dispensers. I need.

There is a need for alternative effective cleaning compositions that provide the desired cleaning results while at the same time reducing the number of components required for cleaning and rinsing.

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 the aliphatic substituents. One contains about 8-18 carbon atoms and one contains anionic water solubilizing groups such as carboxy, sulfo, sulfato, phospato, or phosphono. Amphoteric surfactants are subdivided into two major classes known in the art, described in "Surfactant Encyclopedia" Cosmetics & Toiletries, Vol. 104 (2) 69-71 (1989). , Incorporated herein by reference in its entirety). The first class includes acyl / dialkylethylenediamine derivatives (eg 2-alkylhydroxyethylimidazoline derivatives) and salts thereof. The second class includes N-alkyl amino acids and salts thereof. Some amphoteric surfactants are assumed to fall into both classes.

The amphoteric surfactant can be synthesized by a method known to those skilled in the art. For example, 2-alkylhydroxyethylimidazoline is synthesized by condensation and ring closure of a long-chain carboxylic acid (or a derivative thereof) with dialkylethylenediamine. Commercially available 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 bonding with different alkylating agents results in different tertiary amines.

The long-chain imidazole derivative used in the present invention generally has 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 an anion (generally sodium).

Long-chain N-alkyl amino acids are _{readily prepared by the reaction of RNH 2} (where R = C _8- C ₁₈ linear or branched chain alkyl) aliphatic amines with halogenated carboxylic acids. Alkylation of the primary amino groups 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 beta-alanine or alkyl derivatives of beta-N (2-carboxyethyl) alanine. Examples of commercially available N-alkylamino acid amphoteric electrolytes for use in the present invention include alkylbeta-aminodipropionate _{, RN (C 2} H ₄ COOM) _{2 , and RNHC 2} H ₄ COOM.

More specifically, the concentrate is diluted with about 1: 250 to about 1: 2,000 concentrate vs. water.

Methods of Use-Washing of Articles in a Dishwasher In certain embodiments, the methods of the invention include using to provide the alkaline 2-in-1 detergent composition disclosed herein. In particular, the method of use preferably comprises using a solid alkaline 2-in-1 detergent composition, which is inserted into a dishwasher, particularly a dispenser associated with an industrial dishwasher. In certain embodiments of the invention, the solid composition can be provided as a multi-use dose having a dose of about 10 to about 10,000 per solid composition. In another aspect of the invention, the solid composition can be incorporated into a single-use composition that is used once in a single wash. This method also uses an alkaline 2-in-1 detergent composition and water to produce a cleaning solution, contacting the cleaning solution with stains on the article in a dishwasher, and another rinse aid composition. Includes rinsing items with drinking water without the need for use of items. This rinse is done only with drinking water.

In another embodiment, the methods of the invention provide the individual components of a 2-in-1 detergent composition separately and mix the individual components in situ with water to obtain the desired cleaning solution. Can include producing.

When carrying out the method of the present invention, the 2-in-1 detergent composition described above is inserted into the dispenser of the dishwasher. The dispenser can be selected from a variety of different dispensers, depending on the physical shape of the composition. For example, the liquid composition uses a pump of either a peristaltic pump or a bellows pump and uses a water-soluble packet such as syringe / plunger infusion, gravity feed, siphon feed, aspirator, eg polyvinyl alcohol or foil pouch 1 It can be dispensed by dose, drainage from the pressurization chamber, or diffusion through a membrane or permeable surface. If the composition is a gel or a thick liquid, the composition uses a pump, either a peristal pump or a bellows pump, to inject a syringe / plunger, a coking gun, such as a water-soluble packet such as polyvinyl alcohol or foil pouch. It can be dispensed by a single dose used, drainage from the pressurization chamber, or diffusion through a membrane or permeable surface. Preferably, when the composition is solid or powder, the composition is a single dose using a spray, flood, auger, shaker, tablet dispenser, eg, 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 in which one component is distributed to one side and the other component is distributed to the other side. These exemplary dispensers are located or related to 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 mounted outside the dishwasher. A single dispenser can be supplied to one or more dishwashers.

Once the 2-in-1 detergent composition is inserted into the dispenser, the dishwasher wash cycle is initiated and a wash solution is produced. The washing solution contains an alkaline 2-in-1 detergent composition and water from the dishwasher. The water may be any type of water, such as hard water, soft water, clean water, or dirty water. The most preferred wash 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. It maintains .5. If the probe allows it to perform both functions, the same probe can be used to measure millivolts by simply switching the probe from pH to millivolts. The dispenser or dishwasher can optionally include a pH probe to measure the pH of the wash solution throughout the wash cycle. The actual concentration or ratio of water to detergent depends on the particular surfactant used. Typical concentration ranges include a maximum of 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 surfactant selected.

When used according to the method of the present invention, the solution used can have a high temperature (ie, heat to a high temperature). In one example, the working solution at temperatures of about 120 ° F to about 185 ° F and about 140 ° F to about 185 ° F is brought into contact with the substrate to be washed. In another example, the working solution at a temperature of about 150 ° F to about 160 ° F is brought into contact with the substrate to be washed.

After the wash solution is generated, the wash solution comes into contact with dirt on the article in the dishwasher. Examples of stains are those commonly encountered in foods, such as proteinaceous stains, hydrophobic fat stains, starchy and sugar-based stains associated with carbohydrates and simple sugars, milk and dairy stains, fruits. And stains on vegetables. Dirt also includes, for example, 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, ceramics and the like. Goods include those commonly found in dishwashers, such as glass, bowls, plates, cups, pots and breads, heat-resistant products such as cookie sheets, cake buns, muffin pots, and silver dishes such as forks and spoons. , Knives, cookware such as wooden spoons, spatulas, rubber scrapers, utility knives, tongs, grill cookware, serving utensils, etc. The cleaning solution can be contacted with dirt in several ways, including spraying, dipping, drainage pump fluid, mist, and spraying.

Once the cleaning solution comes into contact with the dirt, the dirt is removed from the article. Removal of dirt from the article is achieved by the chemical reaction of the cleaning solution with the dirt and the mechanical action of the cleaning solution on the article, depending on how the cleaning solution comes into contact with the article.

Once the stains have been removed, the article is rinsed with drinking water as part of the dishwasher wash cycle, without the use of separate or additional rinse aid compositions.

These methods can include more or fewer steps than those described herein. For example, the method can include additional steps, usually associated with the washing cycle of the dishwasher. For example, the method can optionally include the use of acidic detergents. For example, the method can optionally include an acidic detergent alternating with the listed alkaline detergents.

Method for Producing Composition The compositions of the present invention are liquid products, concentrated liquid products, gelled liquid products, pastes, granules and pelletized solid compositions, powders, solid block compositions, cast solid block compositions, extruded solid blocks. The composition and the like can be included.

Solid granular materials can be made by simply blending the dried solid components in appropriate ratios or by aggregating the materials in an appropriate agglomeration system. The pelletized material can be produced by compressing the solid granular or agglomerated material in a suitable pelletizing apparatus to obtain a pelleted material of the appropriate size. Solid Blocks and Casting Solid block materials can be made by introducing a pre-curing block of material or a castable liquid (which cures in the container to become a solid block) into the container. Suitable containers include disposable plastic containers or water-soluble film containers. Other suitable packaging for compositions includes flexible bags, packets, shrink wraps, and water-soluble films such as polyvinyl alcohol.

The solid detergent composition can be formed using a batch or continuous mixing system. In an exemplary embodiment, a single-screw or twin-screw extruder can be used to combine and mix one or more components with high shear to produce a homogeneous mixture. In some embodiments, the processing temperature is at or below the melting temperature of the components. The treated mixture can be dispensed from the mixer by molding, casting, or other suitable means, where the detergent composition is cured 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, solid detergent compositions treated according to the methods of the invention are substantially homogeneous and dimensionally stable with respect to the distribution of components throughout their mass.

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

In the casting process, the liquid and solid components are introduced into the final mixing system and the components are mixed until they form a substantially homogeneous liquid mixture distributed throughout the mass. In an exemplary embodiment, the ingredients are mixed in a mixer 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 the compressed solid process, fluid solids such as granular solids containing binders or other granular solids (eg, hydrated chelating agents such as hydrated aminocarboxylates, hydrated polycarboxylic acid salts, etc. Or an alkali metal carbonate with a hydrated anionic polymer, hydrated citrate, or hydrated tartrate, etc.) under pressure. In a pressurized solid process, the fluid solid of the composition is placed in a foam (eg, a mold or container). The method can include gently pushing the fluid solid into the foam to produce a solid cleaning composition. The pressure can be applied by a block machine, turntable press, etc. 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 certain embodiments, the method is greater than or equal to about 1 psi, greater than or equal to about 2, greater than or equal to, greater than or equal to about 5, or equal to, or greater than or equal to, greater than or equal to, about 10 psi, low. Pressure can be used. As used herein, the term "psi" or "pounds per square inch" refers to the actual pressure applied to a fluidized solid to be pressurized, a gauge or gauge measured at some point in the pressurizing device. It does not refer to hydraulic pressure. The method can include a curing step of producing a solid cleaning composition. As referred to herein, the uncured composition containing the fluid solid is compressed to provide sufficient surface contact between the particles that make up the fluid solid, and the uncured composition is a stable solid wash. Will solidify into the composition. A sufficient amount of particles in contact with each other (eg, granules) provides the binding of the particles to each other, which is effective in producing a stable solid composition. Including a curing step includes allowing the compressed solid to solidify for a period of time, such as several hours, or about one day (or more). In a further embodiment, the method vibrates a fluid solid in a foam or mold, for example as the method disclosed in US Pat. No. 8,889,048, which is incorporated herein by reference in its entirety. Could include letting.

The use of compressed solids is advanced with conventional solid block or tablet compositions that require high pressure in a tableting machine, or castings that require melting of high energy consuming compositions, and / or expensive equipment. It offers many advantages over extrusion molding, which requires a great deal of technical know-how. Compressed solids overcome these various limitations of other solid preparations in which solid cleaning compositions need to be prepared. In addition, the compressed solid composition retains its shape under conditions in which the composition can 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 mere gravity. The solid may be in various forms such as powders, flakes, granules, pellets, tablets, lozenges, packs, briquettes, bricks, solid blocks, single doses, or other solid forms known to those of skill 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 hardened paste. .. Further, 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, detergent compositions are expected to remain in solid form when exposed to temperatures up to about 100 ° F, especially up to about 120 ° F.

The resulting solid detergent composition is not particularly limited; may 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 molded into powders, granules, or flakes. In an exemplary embodiment, the extruded pellet material formed by the solidification matrix weighs from about 50 g to about 250 g, and the extruded solid formed by the composition weighs about 100 g or more and is formed by the composition. The solid block detergent made has a weight of about 1 to about 10 kg. The solid composition provides a stable source of functional materials. In some embodiments, the solid composition can be dissolved, for example, in an aqueous medium or other medium to make a concentrate and / or a solution for use. This solution can be directed to a storage container for later use and / or dilution, or can be applied directly to the place of use.

Examples 1-4
The materials used in Examples 1 to 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 to 4, exemplary 2-in-1 detergents have been prepared and are shown in Table 2. Through Examples 1 to 4, the formulation is also referred to as Experimental Formulation 1 (Experiment 1).

Existing detergents, rinsing aids, and Experimental Formulation 1 were tested against distilled water. Detergent Control 1 and Control 2 were commercially available surfactants (phosphate-based surfactants). Rinse Aid Control 1 and Rinse Aid Control 2 are two commercially available rinse aids (using more active ingredient surfactants in at least two ionic categories (eg, nonionic and cationic)). there were. The concentrations used for all experiments described below are provided in the table below.

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

Example 1
Dynamic surface tension
The 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 that 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 surfactants under dynamic conditions, i.e., how fast surfactants can reach the surface. Dynamic surface tension is a function of surfactant concentration, temperature, and type. The behavior of the dynamic surface tension of surfactants is particularly important in applications where rapid response of surfactants is required, for example in short rinse cycles of automatic dishwashers.

Equipment and materials:
1. 1. SITA T60 (Sita Messtechnik, Germany)
2. Oil bath with a stir bar 3. Heating and stirring plate 4. Glass beaker 5. Glass vial (20 ml)

SITA Science line t60 was calibrated with DI water. The calibrated clean water sample should have a surface tension of 72.0 ± 1.0 mN / m (depending on water quality and temperature). After calibration, SITA was programmed to read at desired time intervals (ie 0.3, 1.6, 3.0, and 9.1 seconds). For each composition to be tested (denoted as Samples A-C) (eg, 3 samples from Experiment 1 and 3 samples from Detergent Control 1), 3 separate solutions of the desired ppm were prepared. 10 to 15 ml was transferred to a 20 ml vial and immersed in an oil bath heated to 72 ° C. (160 ° F) ± 2 ° C. The sample was equilibrated for 10 to 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 SITA was sufficiently clean. If 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) anti-bubble lifetime at 160 ° F are shown in Tables 4A-4F below, where τ is the bubble lifetime (S) and γ is the surface tension (mN / m). ).

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

The data show that the surface tension of Experimental Formula 1 drops rapidly due to a significant drop in surface tension over a bubble lifetime of 9.1 seconds. This is similar to a well-performing rinse aid such as rinse aid control 2. These results are shown in FIG.

Example 2
100 Cycle Membrane Evaluation of Commercial Dishwashing Detergents Six by removing all membranes and foreign matter from the surface of the glass to examine the ability of various detergent compositions to remove stains and membranes from tableware. A Libbey 10 oz glass tumbler was prepared. Next, the Hobart AM-15 dishwasher was filled with an appropriate amount of water and the hardness of the water was examined. After recording the hardness value, the tank heater was turned on. On the day of the experiment, the hardness of the water was 17 grains. The dishwasher was turned on and the 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 up and an appropriate amount of detergent was placed in the washing 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 produce the working solution. The solution in the washing tank was titrated to confirm the detergent concentration. The dishwasher had a washing bath capacity of 58 liters, a rinsing capacity of 2.8 liters, a washing time of 50 seconds, and a rinsing time of 9 seconds.

Place 6 clean glass tumblers diagonally in the Raburn rack, 4 Newport 10 oz plastic tumblers off the diagonal in the Raburn rack (see figure below for placement), and dishwash the rack. I put it inside the machine (P = plastic tumbler; G = glass tumbler).

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

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

The optical box test used a digital camera, optical box, light source, light meter, and a control computer using "Spot Advance" and "Image Pro Plus" commercial software. The glass to be evaluated was placed on the light box sideways, 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 saved on a computer. Then using the software to analyze the upper half of the glass, 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 was able to pass through the tumbler. That is, the smaller the light box score, the more effective the composition was in preventing scale formation on the tumbler surface. A clean, unused glass tumbler has a light box score of about 12,000, which is equivalent to a score of 72,000 for 6 glass tumblers, and a clean, unused plastic tumbler is about 25. It has an optical box score of, 500, which corresponds to an optical box score of about 102,000 for four plastic tumblers. The minimum light box score obtained (ie, the sum 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 to be effective in controlling the scale formation of hard water. Be done.

The results of the 100-cycle test are shown in Tables 7-8 and give average film scores for glass and plastic tumblers.

Example 3
50-cycle redeposition experiment of commercial dishwashing detergent The cleaning effect of the compositions and controls according to the present invention was further evaluated using a 50-cycle redeposition experiment of commercial dishwashing detergent. Six 10 ounce Libbey heat resistant glass tumblers and one plastic tumbler were used to test the composition's ability to clean glass and plastic. The glass tumbler was cleaned before use. A new plastic tumbler was used in each experiment.

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

After filling the dishwasher 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. The glass tumbler and plastic tumbler were placed in a Raburn rack (see figure below for placement; P = plastic tumbler, G = glass tumbler) and the rack was placed in the dishwasher.

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

At the end of the 50 cycles, the glass was dried overnight. The glass was then graded for stain and membrane accumulation (visually).

Coomassie Brilliant Blue R staining was then used, followed by decolorization with acetic acid / methanol solution to grade glass tumblers and plastic tumblers for protein accumulation. The 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 decolorizing solution consisted of 45% methanol and 10% acetic acid in distilled water.

The amount of protein remaining on the glass tumbler and plastic tumbler after bleaching was visually evaluated on a scale of 1-5. A score of 1 indicated that the protein was absent after bleaching-no stain / no membrane. Score 2 showed that random sites were (barely identifiable) covered with protein after bleaching-random stains (or about 20% of the surface was covered with a membrane). A score of 3 showed that after bleaching, about one-quarter to half of the surface was covered with protein (ie, about 40% of the surface was covered with a membrane). A score of 4 showed that after bleaching, about half of the glass / plastic surface was covered with protein (ie, about 60% of the surface was covered with a film). A score of 5 showed that after bleaching, the entire surface was covered with protein (ie, at least about 80% of the surface was covered with a membrane).

The average stain removal score from the glass surface was determined by averaging the scores of the glass tumblers tested for stain removal, and the average stain removal score from the plastic surface was averaged from the plastic tumblers tested for stain removal. It was determined. Similarly, the average redeposition score of the glass surface was determined by averaging the scores of the glass tumblers tested for redeposition, and the average redeposition of the plastic surface was averaged by averaging the scores of the plastic tumblers tested for redeposition. The score was decided.

The results are shown in the table below, showing that the detergent compositions according to the invention provide at least substantially similar cleaning effects and, in various embodiments, provide superior effects over commercial products. The score scale is shown in Table 9.

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

Example 4
7-cycle stain, film, and stain removal assessment of commercial dishwashing detergents or rinsing aids 12 10 oz Libbey heat resistant glass tumblers and 4 to test the composition's ability to clean glass and plastic Newport plastic tumbler was used. The glass tumbler was cleaned before use.

A food stain solution was prepared using a 50/50 combination of beef stew and hot point stain. The concentration of this solution was about 2000 ppm. The stain contained two cans of Dinty Moore Beef Stew (1360 g), one 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. The glass was rotated three times in a 1: 1 (volume) mixture of Campbell's Cream of Chicken Soup: Kemp's Whole Milk to stain the glass tumbler and the plastic tumbler. The glass was then placed in an oven at about 160 ° F for 8 minutes. While the glass was drying, the dishwasher was charged with about 120 g of food stain solution, which corresponds to about 2000 ppm of food stain in the pump.

The dirty glass tumbler and plastic tumbler were placed in a Raburn rack (see figure below for placement; P = plastic tumbler, G = glass tumbler) and the rack was placed in the dishwasher. The first two rows of tumblers were tested for decontamination 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 was completed, the top of the glass tumbler and plastic tumbler was wiped with a dry towel. The glass tumbler and plastic tumbler tested for stain removal were removed and the soup / milk stain operation was repeated. The redeposited glass and plastic tumbler were not removed.

At the beginning of each cycle, appropriate amounts of detergent and food stains were added to the wash tank as a substitute for rinse dilution. The dirt and cleaning process was repeated for 7 cycles.

Coomassie Brilliant Blue R staining was then used, followed by decolorization with acetic acid / methanol solution to grade glass tumblers and plastic tumblers for protein accumulation. The Coomassie Brilliant Blue R stain was prepared by combining about 1.25 g of Coomassie Brilliant Blue R dye in distilled water with about 45 ml of acetic acid and about 455 ml of 50% methanol. The decolorizing solution consisted of 45% methanol and 10% acetic acid in distilled water. The amount of protein remaining on the glass tumbler and plastic tumbler after bleaching was visually evaluated on a scale of 1-5. A score of 1 indicated that the protein was absent after bleaching. Score 2 showed that random sites were covered with protein (barely identifiable) after bleaching. Score 3 showed that after bleaching, about a quarter of the surface was covered with protein. Score 4 showed that after bleaching, about half of the glass / plastic surface was covered with protein. A score of 5 indicated that the entire surface was covered with protein after bleaching.

The average protein removal score from the glass surface was determined by averaging the scores of the glass tumblers tested for protein removal, and the average protein removal score from the plastic surface was averaged by averaging the scores of the plastic tumblers tested for protein removal. It was determined. Similarly, the scores of the glass tumblers tested for redeposition were averaged to determine the average protein redeposition score on the glass surface, and the scores of the plastic tumblers tested for protein redeposition were averaged to average the plastic surface. The protein redeposition score was determined.

Glass was visually evaluated in the glass field of view against a black background. Each set of glass was evaluated as a set, i.e. all redeposited glass was evaluated for all products tested. For each set, the overall average can be determined. The evaluation scales used are shown in Table 12.

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

The behavior of the dynamic surface tension of surfactants is particularly important in applications where rapid response of surfactants is required, for example in short rinse cycles of automatic dishwashers.

Equipment and materials:
1. 1. SITA T60 (Sita Messtechnik, Germany)
2. Oil bath with a stir bar 3. Heating and stirring plate 4. Glass beaker 5. Glass vial (20 ml)

SITA Science line t60 was calibrated with DI water. The calibrated clean water sample should have a surface tension of 72.0 ± 1.0 mN / m (depending on water quality and temperature). After calibration, SITA was programmed to read at desired time intervals (ie 0.3, 1.6, 3.0, and 9.1 seconds). For each composition to be tested (denoted as AC), three separate solutions of the desired ppm (eg, three samples from Experiment 2 and three samples from Detergent Control 1) were prepared. 10 to 15 ml was transferred to a 20 ml vial and immersed in an oil bath heated to 72 ° C (160 ° F) ± 2 ° C. The sample was equilibrated for 10 to 15 minutes. Samples were individually removed from the oil bath and tested with SITA. After testing each sample, SITA washes were performed, and then the surface tension of DI water was checked to confirm that SITA was sufficiently clean. If 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) anti-bubble lifetime at 160 ° F are shown in Tables 17A to 17F below, where τ is the bubble lifetime (seconds) and γ is the surface tension (mN / m). ).

The average surface tension at 160 ° F was tested for average cell 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 Formulation 2 drops rapidly due to a significant drop in surface tension over a bubble lifetime of 9.1 seconds. This is similar to a well-performing rinse aid such as rinse aid control 2. These results are shown in FIG.

100 Cycle Membrane Evaluation of Commercial Dishwashing Detergents Six by removing all membranes and foreign matter from the surface of the glass to examine the ability of various detergent compositions to remove stains and membranes from tableware. A Libbey 10 oz glass tumbler was prepared. Next, the Hobart AM-15 dishwasher was filled with an appropriate amount of water and the hardness of the water was examined. After recording the hardness value, the tank heater was turned on. On the day of the experiment, the hardness of the water was 17 grains. The dishwasher was turned on and the 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 up and an appropriate amount of detergent was placed in the washing 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 produce the working solution. The solution in the washing tank was titrated to confirm the detergent concentration. The dishwasher had a washing bath capacity of 58 liters, a rinsing capacity of 2.8 liters, a washing time of 50 seconds, and a rinsing time of 9 seconds.

Place 6 clean glass tumblers diagonally in the Raburn rack, 4 Newport 10 oz plastic tumblers off the diagonal in the Raburn rack (see figure below for placement), and dishwash the rack. I put it inside the machine (P = plastic tumbler; G = glass tumbler).

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

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

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

The optical box test used a digital camera, optical box, light source, light meter, and a control computer using "Spot Advance" and "Image Pro Plus" commercial software. The glass to be evaluated was placed on the light box sideways, and the intensity of the light source was adjusted to a predetermined value using an exposure meter. I took a photographic image of the glass and saved it on my computer. Next, using the software to analyze the upper half of the glass, 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 can pass through the tumbler. That is, the smaller the light box score, the more effective the composition was in preventing scale formation on the tumbler surface. A clean, unused glass tumbler has a light box score of about 12,000, which is equivalent to a score of 72,000 for 6 glass tumblers, and a clean, unused plastic tumbler is about 25. It has an optical box score of, 500, which corresponds to an optical box score of about 102,000 for four plastic tumblers. The minimum light box score obtained (ie, the sum 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 to be effective in controlling the scale formation of hard water. ..

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

Example 7
50-cycle redeposition experiment of commercial dishwashing detergent The cleaning effect of the compositions and controls according to the present invention was further evaluated using a 50-cycle redeposition experiment of commercial dishwashing detergent. Six 10 ounce Libbey heat resistant glass tumblers and one plastic tumbler were used to test the composition's ability to clean glass and plastic. The glass tumbler was cleaned before use. A new plastic tumbler was used in each experiment.

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

After filling the dishwasher 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. The glass tumbler and plastic tumbler were placed in a Raburn rack (see figure below for placement; P = plastic tumbler, G = glass tumbler) and the rack was placed in the dishwasher.

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

At the end of the 50 cycles, the glass was dried overnight. The glass was then graded for stain and membrane accumulation (visually).

The Coomassie Brilliant Blue R stain was then used, then decolorized with an acetic acid / methanol solution to grade the glass tumblers and plastic tumblers for protein accumulation. The 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 decolorizing solution consisted of 45% methanol and 10% acetic acid in distilled water.

The amount of protein remaining on the glass tumbler and plastic tumbler after bleaching was visually evaluated on a scale of 1-5. A score of 1 indicated that the protein was absent after bleaching-no stain / no membrane. Score 2 was a random stain (or about 20% of the surface was covered with a membrane) indicating that random sites (barely identifiable) were covered with protein after bleaching. A score of 3 showed that after bleaching, about one-quarter to half of the surface was covered with protein (ie, about 40% of the surface was covered with a membrane). A score of 4 showed that after bleaching, about half of the glass / plastic surface was covered with protein (ie, about 60% of the surface was covered with a film). A score of 5 indicates that the entire surface was covered with protein after decolorization (ie, at least about 80% of the surface was covered with a film).

The average stain removal score from the glass surface was determined by averaging the scores of the glass tumblers tested for stain removal, and the average stain removal score from the plastic surface was averaged from the plastic tumblers tested for stain removal. It was determined. Similarly, the average redeposition score of the glass surface was determined by averaging the scores of the glass tumblers tested for redeposition, and the average redeposition of the plastic surface was averaged by averaging the scores of the plastic tumblers tested for redeposition. The score was decided.

The results are shown in the table below, showing that the detergent compositions according to the invention provide at least substantially similar cleaning effects and, in various embodiments, better than commercial products. The scoring scale is shown in Table 22.

The results of the 50-cycle test are shown in Tables 23 and 24.

Example 8

A food stain solution was prepared using a 50/50 combination of beef stew and hot point stain. The concentration of this solution was about 2000 ppm. The stain contained two cans of Dinty Moore Beef Stew (1360 g), one 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. The glass was rotated three times in a 1: 1 (volume) mixture of Campbell's Cream of Chicken Soup: Kemp's Whole Milk to stain the glass tumbler and the plastic tumbler. The glass was then placed in an oven at about 160 ° F for 8 minutes. While the glass was drying, the dishwasher was charged with about 120 g of food stain solution, which corresponds to about 2000 ppm of food stain in the pump.

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

Next, the dishwasher was started and operated in an automatic cycle. After the automatic cycle was completed, the top of the glass tumbler and plastic tumbler was wiped with a dry towel. The glass tumbler and plastic tumbler tested for stain removal were removed and the soup / milk stain operation was repeated. The redeposited glass and plastic tumbler were not removed.

At the beginning of each cycle, appropriate amounts of detergent and food stains were added to the wash tank as a substitute for rinse dilution. The dirt and cleaning process was repeated for 7 cycles.

The Coomassie Brilliant Blue R stain was then used, then decolorized with an acetic acid / methanol solution to grade the glass tumblers and plastic tumblers for protein accumulation. The Coomassie Brilliant Blue R stain was prepared by combining about 1.25 g of Coomassie Brilliant Blue R dye in distilled water with about 45 ml of acetic acid and about 455 ml of 50% methanol. The decolorizing solution consisted of 45% methanol and 10% acetic acid in distilled water. The amount of protein remaining on the glass tumbler and plastic tumbler after bleaching was visually evaluated on a scale of 1-5. A score of 1 indicated that the protein was absent after bleaching. A score of 2 indicates that the random sites were covered with protein (barely identifiable) after bleaching. Score 3 showed that after bleaching, about a quarter of the surface was covered with protein. Score 4 showed that after bleaching, about half of the glass / plastic surface was covered with protein. A score of 5 indicated that the entire surface was covered with protein after bleaching.

The average protein removal score from the glass surface was determined by averaging the scores of the glass tumblers tested for protein removal, and the average protein removal score from the plastic surface was averaged by averaging the scores of the plastic tumblers tested for protein removal. It was determined. Similarly, the scores of the glass tumblers tested for redeposition were averaged to determine the average protein redeposition score on the glass surface, and the scores of the plastic tumblers tested for protein redeposition were averaged to average the plastic surface. The protein redeposition score was determined.

Evaluation results:
Glass was visually evaluated in the glass field of view against a black background. Each set of glass is evaluated as a set, i.e. all redeposited glass is evaluated for all products tested. For each set, the overall average can be determined. The evaluation scales used are shown in Table 25.

The results of the 7-cycle test are shown in Tables 26 and 27, showing the mean stain, membrane, and protein staining scores (with standard deviation) for glass tumblers and plastic tumblers.
