Description

[Technical field]

[0001] The embodiments herein generally relate to the field of ware sanitizing and rinsing aid compositions and methods of using the same. In particular, the sanitizing and rinsing aid compositions disclosed herein have excellent antimicrobial activity and can be used as dual-function integrated sanitizing and rinsing aids with surface activity and enzyme compatibility. Methods of using the sanitizing and rinsing aid compositions are also disclosed. [Background technology]

[0002] Antimicrobial agents are chemical compositions used to prevent microbiological contamination and deterioration of products, materials, and systems. Antimicrobial agents and compositions are used as disinfectants or sanitizers in connection with hard surface cleaning, food preparation, animal feed, cooling water, hospitality services, hospital and medical applications, as well as pulp and paper manufacturing, and textile cleaning. Among the diverse categories of antimicrobial agents and compositions, quaternary ammonium compounds represent one of the largest classes of agents used. At low concentrations, quaternary ammonium type antimicrobial agents are bacteriostatic, fungistatic, algaestatic, sporostatic, and tuberculostatic. At moderate concentrations, they are bactericidal, fungicidal, algaestatic, and virucidal against lipophilic viruses. It is desirable to enhance the antimicrobial activity of such chemicals for use in various applications.

[0003] Mechanical warewashing machines, including dishwashers, have been common in institutional and domestic environments for many years. Such automatic warewashing machines wash dishes using two or more cycles, which may include an initial wash cycle followed by a rinse cycle. Such automatic warewashing machines may also utilize other cycles, such as a soak cycle, a pre-wash cycle, a scrubbing cycle, an additional wash cycle, an additional rinse cycle, a sanitizing cycle, and / or a drying cycle. Any of these cycles may be repeated as desired, and additional cycles may be used. Rinse aids are traditionally used in warewashing applications to promote drying and prevent the formation of spots on the ware being washed.

[0004] To reduce spot formation, rinse agents are typically added to water to form a rinse liquid that is sprayed onto the ware after the wash is complete. The exact mechanism by which rinse agents work has not been established. One theory is that the surfactants in the rinse agent are absorbed onto the surface at temperatures above their cloud point, thereby reducing the solid-liquid interfacial energy and contact angle. This results in the formation of a continuous sheet that drains evenly from the surface and minimizes spot formation. Generally, high foaming surfactants have a cloud point higher than the rinse water temperature, which, according to this theory, does not promote sheet formation, thereby causing spots. Additionally, high foaming materials are known to interfere with the operation of warewashing machines.

[0005] In addition to detergents and disinfectants, rinse aids are also conventionally used in ware washing applications to accelerate drying and prevent the formation of spots on the ware being washed. To reduce the formation of spots, rinse aids are generally added to water to form a rinse liquid, which is sprayed onto the ware after washing is completed. Many rinse aids are currently known, such as those disclosed in U.S. Patents 3,592,774, 3,625,901, 3,941,713, 4,005,024, 4,187,121, 4,147,559, and 4,624,713, each of which has certain advantages and disadvantages. Further disclosure of rinse aids containing nonionic surfactants is disclosed in Schick, "Nonionic Surfactants," Soap and Chemical Specialties, published by Marcel Dekker and John L. Wilson, February 1958, pp. 48-52 and 170-171, the entire contents of which are incorporated herein by reference.

[0006] There is still a continuing need for alternative and improved rinse aid compositions.There is also still a continuing need for improved dishwasher effectiveness, including maximizing the effectiveness of detergent, sanitizer, and / or rinse aid combinations.Current sanitizing rinse aids generally use chlorine, oxidizing agents, and quaternary ammonium chloride compounds.These compounds can, for example, be corrosive due to their oxidizing capabilities, or be incompatible with enzymes, thereby reducing the beneficial properties of the composition. Summary of the Invention [Problem to be solved by the invention]

[0007] It is therefore a feature of the present disclosure to develop concentrated use liquid and solid compositions and methods of using same in warewashing applications to provide desirable disinfectant rinse aids using amine-based surfactants not known for use as disinfectants in mechanical warewashing applications.

[0008] It is a further feature of the present disclosure to provide a sanitizing rinse aid using an amine surfactant compound that is effective in low temperature warewash applications.

[0009] A further feature of the present disclosure is to provide a disinfectant rinse aid that is free of chlorine, oxidizers, and quaternary ammonium chlorides.

[0010] Other embodiments, advantages, and features of the present disclosure will become apparent from the following specification taken in conjunction with the accompanying drawings. [Means for solving the problem]

[0011] The advantage of the present disclosure is the concept that amine surfactants can function as sanitizers in warewashing applications as part of cleaning compositions or rinse aids.Advantageously, sanitizing compositions are suitable for use in both low-temperature and high-temperature warewashing applications, including commercial machine sanitizing.Formulations based on sanitizing amine surfactant compounds are particularly suitable for low-temperature and low-foaming applications, including, for example, combination products of automatic dishwashing rinse aids and sanitizers, or dual-function all-in-one sanitizing rinses.

[0012] In some embodiments, the compositions and methods of making same provide a germicidal cleaning / rinsing composition comprising an amine surfactant having germicidal activity. In one aspect, a germicidal rinsing / rinsing composition is provided comprising an amine surfactant having the general formula: [ka] In the formula, the group R 1 is a linear or branched, saturated or unsaturated C 6 -C 18 is an alkyl group or H, R 2 and R 3 But, H, (CH 2 ) 3 NH 2 , (CH 2 ) 3 NHCH 2 COOH, CH 2COOH, (CH 2 ) 3 N(CH 2 COOH) 2 , (CH 2 ) 3 NH 2 In one embodiment, the disinfectant rinse composition is provided as a use solution having a pH of 1 to 13, a pH of about 5 to about 13, or a pH of about 7 to about 12, or a pH of about 7 to about 9. In one embodiment, the disinfectant rinse composition is substantially free of chlorine, oxidizing agents, and other disinfecting compounds such as quaternary ammonium chlorides, and acts as a non-oxidizing disinfectant.

[0013] In one embodiment, the present disclosure provides a dual-function all-in-one germicidal rinse composition.In a further embodiment, the present disclosure provides a method of using the dual-function all-in-one germicidal rinse composition.A method of rinsing a surface or object and providing germicidal antimicrobial effectiveness is provided, comprising applying to a substrate an amine surfactant composition disclosed by various embodiments.In one aspect, the combination provides at least 5 log kill.

[0014] Further embodiments may also include a non-ionic surfactant as a foam suppressor or defoamer in combination with the germicidal surfactant.

[0015] Methods of making the compositions are also contemplated.

[0016] While multiple embodiments are disclosed, still other embodiments of the present disclosure will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the present disclosure. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive. [Brief description of the drawings]

[0018] Various embodiments of the detergent compositions and their methods of use will be described in detail with reference to the drawings. Reference to various embodiments is not intended to limit the scope of the present disclosure. The drawings shown herein are presented for illustrative purposes of the detergent compositions disclosed herein, not as a limitation to the various embodiments. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The embodiments of the present disclosure are not limited to specific compositions, methods of making and / or using them for rinsing and other applications, which may vary and are understood by those skilled in the art. In order to make the present disclosure easier to understand, certain terms are first defined. It should be further understood that all technical terms used herein are merely for the purpose of describing specific embodiments, and are not intended to be limiting in any manner or scope. For example, when used in this specification and the appended claims, the singular forms "a", "an" and "the" can include plural referents unless the content clearly indicates otherwise. Furthermore, all units, prefixes and symbols can be indicated in their SI recognized form.

[0020] Numerical ranges described herein are inclusive of the numbers defining the range and include each integer within the defined range. Throughout this disclosure, various aspects of the disclosure are presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an indefinite limitation on the scope of the disclosure. Thus, the description of a range should be considered to have specifically disclosed all possible subranges, fractions, and individual numbers within that range. For example, the description of a range such as 1-6 should be considered to have specifically disclosed subranges such as 1-3, 1-4, 1-5, 2-4, 2-6, 3-6, etc., as well as individual numbers within that range, such as 1, 2, 3, 4, 5, and 6, and decimals and fractions, such as 1.2, 3.8, 1 and 1 / 2, and 4 and 3 / 4. This applies regardless of the breadth of the range.

[0021] definition In order to make the detergent composition disclosed herein and its use easier to understand, certain terms are defined first.Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art related to the embodiments of the present disclosure.Many methods and materials similar to those described herein, modified or equivalent to those described herein can be used to practice the embodiments of the present disclosure without undue experimentation, and preferred materials and methods are described herein.In describing and claiming the embodiments of the present disclosure, the following technical terms will be used according to the definitions described below.

[0022] The term "about" as used herein refers to variations in quantity that may occur, for example, due to typical measuring and liquid handling procedures used to make concentrates or use solutions in the real world, due to inadvertent errors in these procedures, due to differences in manufacture, source, or purity of ingredients used to make the composition or carry out the method. The term "about" also encompasses amounts that differ due to different equilibrium conditions for a composition resulting from a particular initial mixture. Whether or not modified by the term "about," the claims include the equivalent of the amount.

[0023] The terms "actives" or "percent actives" or "percent actives by weight" or "actives concentration" are used interchangeably herein and refer to the concentration of ingredients involved in cleaning expressed as a percentage minus inactive ingredients such as water or salt.

[0024] As used herein, the term "cleaning" refers to methods used to promote or aid in stain removal, bleaching, microbial population reduction, and any combination thereof. As used herein, the term "microorganism" refers to any non-cellular or unicellular (including colonial) organism. Microorganisms include all prokaryotes. Microorganisms include bacteria (including cyanobacteria), spores, lichens, fungi, protozoa, virinos, viroids, viruses, phages, and some algae. As used herein, the term "microbe" is synonymous with microorganism.

[0025] For purposes of this patent application, successful microbial reduction is achieved when the microbial population is reduced by at least about 50%, or significantly more than is achieved by washing with water. The greater the reduction in microbial population, the greater the level of protection.

[0026] As used herein, the term "sanitizer" refers to an agent that reduces the number of bacterial contaminants to a safe level as determined by public health requirements. In one embodiment, the sanitizer for use in the present disclosure will provide at least a 99.999% reduction (a 5-log order reduction). These reductions can be evaluated using the procedures set forth in Germicidal and Detergent Sanitizing Action of Disinfectants, Official Methods of Analysis of the Association of Official Analytical Chemists, paragraph 960.09 and relevant portions, 15th Edition, 1990 (EPA Guideline 91-2). According to this reference, a sanitizer should provide a 99.999% reduction (a 5-log order reduction) against several test organisms within 30 seconds at room temperature, 25±2°C. According to an embodiment of the present disclosure, the sanitizing rinse provides a 99.999% reduction (a 5-log order reduction) of the organisms of interest (including bacterial contaminants) at the temperature of use. The distinction between antimicrobial "cidal" or "static" activity, definitions describing the degree of effectiveness, and official laboratory protocols for measuring this effectiveness are considerations for understanding the relevance of antimicrobial agents and compositions. Antimicrobial compositions can produce two types of microbial cell damage. The first is a lethal, irreversible action, resulting in the complete destruction or incapacitation of the microbial cell. The second type of cell damage is reversible, so that the organism can reproduce again when it is no longer carrying the agent. The former is called microbiocidal and the latter microbistatic. Sanitizers and disinfectants are, by definition, agents that provide antimicrobial or microbicidal activity. In contrast, preservatives are generally described as inhibitors or microbistatic compositions.

[0027] As used herein, the terms "substantially free," "free," "free from," "substantially free of," or "free of" refer to a composition that is completely devoid of the component or has such a small amount of the component that it does not affect the performance of the composition. The component may be present as an impurity or contaminant and should be less than 0.5% by weight. In another embodiment, the amount of the component is less than 0.1% by weight, and in yet another embodiment, the amount of the component is less than about 0.01% by weight, less than 0.001% by weight, less than 0.0001% by weight, or less than 0.00001% by weight.

[0028] As used herein, the term "alkyl" or "alkyl group" refers to a saturated hydrocarbon having one or more carbon atoms, and includes straight-chain alkyl groups (e.g., methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, etc.), cyclic alkyl groups (or "cycloalkyl" or "alicyclic" or "carbocyclic" groups) (e.g., cyclopropyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, etc.), branched-chain alkyl groups (e.g., isopropyl, tert-butyl, sec-butyl, isobutyl, etc.), and alkyl substituted alkyl groups (e.g., alkyl substituted cycloalkyl groups and cycloalkyl substituted alkyl groups).

[0029] Unless otherwise specified, the term "alkyl" includes both "unsubstituted alkyl" and "substituted alkyl." As used herein, the term "substituted alkyl" refers to an alkyl group having substituents replacing one or more hydrogens on one or more carbons of the hydrocarbon backbone. Such substituents include, for example, alkenyl, alkynyl, halogeno, hydroxyl, alkylcarbonyloxy, arylcarbonyloxy, alkoxycarbonyloxy, aryloxy, aryloxycarbonyloxy, carboxylate, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkylthiocarbonyl, alkoxyl, phosphate, phosphonato, phosphinato, cyano, aryloxy ... The substituents may include no, amino (including alkylamino, dialkylamino, arylamino, diarylamino, and alkylarylamino), acylamino (including alkylcarbonylamino, arylcarbonylamino, carbamoyl, and ureido), imino, sulfhydryl, alkylthio, arylthio, thiocarboxylate, sulfate, alkylsulfinyl, sulfonate, sulfamoyl, sulfonamido, nitro, trifluoromethyl, cyano, azido, heterocyclic, alkylaryl, or aromatic (including heteroaromatic) groups.

[0030] "Anti-redeposition agents" refer to compounds that help soils remain suspended in water instead of redepositing onto the object being cleaned. Anti-redeposition agents are useful in the present disclosure to help reduce the redeposition of removed soils onto the surface being cleaned.

[0031] The term "threshold agent" refers to a compound that inhibits the crystallization of hard water ions from a solution, but does not have to form a specific complex with the hard water ions. Threshold agents suitable for various cleaning applications include, but are not limited to, polycarboxylic acid polymers, polyacrylates, polymethacrylates, olefin / maleic acid copolymers, and the like.

[0032] As used herein, the term "polymer" generally includes, but is not limited to, homopolymers, copolymers, such as block, graft, random, and alternating copolymers, terpolymers, and higher order "x"-mers, further including derivatives, combinations, and blends thereof. Furthermore, unless otherwise specifically limited, the term "polymer" is intended to include all possible isomeric configurations of the molecule, including, but not limited to, isotactic, syndiotactic, and random symmetries, and combinations thereof. Furthermore, unless otherwise specifically limited, the term "polymer" is intended to include all possible geometric configurations of the molecule.

[0033] As used herein, the term "surfactant" is a compound containing lipophilic and hydrophilic segments that, when added to water or solvent, reduces the surface tension of the system.

[0034] As used herein, the term "ware" generally refers to items such as tableware and cookware, dishes, and other hard surfaces. Ware also refers to items made of various substrates, including glass, ceramic, china, quartz, metal, plastic, or natural materials (such as, but not limited to, clay, bamboo, hemp, etc.). Types of plastics that can be cleaned with compositions according to the present disclosure include, but are not limited to, those that include polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE), polyvinyl chloride (PVC), styrene acrylonitrile (SAN), polycarbonate (PC), melamine formaldehyde resin or melamine resin (melamine), acrylonitrile-butadiene-styrene (ABS), and polysulfone (PS). Other exemplary plastics that can be cleaned using the detergent compositions disclosed herein include polyethylene terephthalate (PET) polystyrene polyamide. As used herein, the term "ware washing" refers to washing, cleaning, or rinsing of ware.

[0035] As used herein, the term "soil" refers to polar or non-polar organic or inorganic materials including, but not limited to, carbohydrates, proteins, fats, oils, etc. These materials may exist in their organic state or may be complexed with metals to form inorganic complexes.

[0036] As used herein, the term "stain" refers to polar or non-polar materials that may or may not contain particulate matter such as metal oxides, metal hydroxides, metal oxide-hydroxides, clay, sand, dust, natural products, carbon black, graphite, and the like.

[0037] The terms "weight percent," "wt%," "percent by weight," "% by weight," and variations thereof, as used herein, refer to the concentration of a substance by dividing the weight of that substance by the total weight of the composition and multiplying by 100. As used herein, it is understood that "percent," "%," and the like are intended to be synonymous with "weight percent," "% by weight," and the like.

[0038] The methods and compositions of the present disclosure may comprise, consist essentially of, or consist of the components and ingredients of the present disclosure, as well as other components described herein. As used herein, "consisting essentially of" means that the methods and compositions may include additional steps, components, or ingredients, so long as the additional steps, components, or ingredients do not materially alter the basic and novel characteristics of the claimed methods and compositions.

[0039] Germicidal cleaning or dual-function integrated germicidal rinsing composition The present disclosure relates to dishwashing and / or rinse aid compositions having at least one germicidal amine surfactant and may also include a nonionic surfactant. Exemplary ranges of rinse compositions are provided in Tables 1A-1C, by weight percent of the detergent composition. [Table 1] [Table 2] [Table 3]

[0040] The germicidal cleaning or rinse aid composition may include concentrated solid and / or liquid compositions, or may be diluted to form use compositions as well as ready-to-use compositions. In general, a concentrate refers to a composition that is intended to be diluted with water to provide a use solution that contacts an object to provide the desired cleaning, rinsing, etc. The cleaning / rinse aid composition that contacts the item or vessel to be cleaned may be referred to as a concentrate or a use composition (or use solution), depending on the formulation used in the method. It should be understood that the concentrations of germicidal amine surfactants and other ingredients will vary depending on whether the cleaning composition is provided as a concentrate or a use solution.

[0041] A use solution may be prepared from the concentrate by diluting the concentrate with a solvent, such as water, at a dilution ratio that provides a use solution with the desired detergent properties. The water used to dilute the concentrate to form the use composition may be referred to as dilution water or diluent, which may vary from location to location. A typical dilution factor is about 1 to about 10,000, but this will depend on factors including water hardness, amount of soil to be removed, and the like. In one embodiment, the concentrate is diluted at a concentrate to water ratio of about 1:10 to about 1:10,000. Specifically, the concentrate is diluted at a concentrate to water ratio of about 1:100 to about 1:5,000. More specifically, the concentrate is diluted at a concentrate to water ratio of about 1:250 to about 1:2,000. In some embodiments, the composition is used in its concentrated form.

[0042] In one embodiment, the use solution of the cleaning composition has about 1 ppm to about 5000 ppm of amine surfactant, and about 1 ppm to about 5000 ppm of antifoaming agent. In a preferred embodiment, the use solution of the cleaning composition has about 10 ppm to about 2000 ppm of amine surfactant, and about 1 ppm to about 2000 ppm of antifoaming agent. In a preferred embodiment, the use solution of the cleaning composition has about 15 ppm to about 1500 ppm of amine surfactant, and about 1 ppm to about 1000 ppm of antifoaming agent. In a preferred embodiment, the use solution contains about 25 ppm or more of amine surfactant at a pH greater than about 5. Additionally, without being limited according to the present disclosure, all recited ranges are inclusive of the numbers defining the range, and include each integer within the defined range.

[0043] The antimicrobial cleaning / rinse aid composition disclosed herein may be a solid concentrate composition. A "solid" composition refers to a composition that is in the form of a solid, such as a powder, particle, aggregate, flake, granule, pellet, tablet, lozenge, puck, briquette, brick, solid block, unit dose, or another solid form known to those skilled in the art. The term "solid" refers to the state of the cleaning / rinse aid composition under the expected storage and use conditions of the solid cleaning / rinse aid composition. In general, the cleaning / rinse aid composition is expected to remain in solid form when exposed to elevated temperatures of 100°F, 112°F, and preferably 120°F. A cast, compressed, or extruded "solid" may take any form, including a block. When referring to a cast, compressed, or extruded solid, it means that the hardened composition will not flow appreciably and will substantially retain its shape under moderate stress, pressure, or simple gravity. For example, the shape of the mold when removed from the mold, the shape of the article formed upon extrusion from an extruder, etc. The degree of hardness of the solid casting composition can range from that of a relatively dense and hard fused solid block, similar to concrete, to a softness characterized as malleable and sponge-like, similar to caulking.

[0044] The cleaning / rinse aid compositions disclosed herein can be made available as concentrates (or as multiple concentrates that are diluted and combined) to provide use solutions for application on a variety of surfaces, i.e., hard surfaces. The advantage of providing concentrates for later combination or dilution is that it is cheaper to ship and store concentrates than use solutions, and they are more sustainable because less packaging is used, thus reducing shipping and storage costs.

[0045] The phrases "cleaning / rinsing aid composition" and "sanitizing cleaning / rinsing aid composition" refer to cleaning / rinsing aid compositions provided as concentrates or use compositions according to the present disclosure, which may be provided in various formulations, including, for example, liquids, solids, powders, pastes, or gels. The term "concentrate" refers to a relatively concentrated form of the cleaning / rinsing aid composition that may be diluted with a diluent to form a use composition. An exemplary diluent that may be used to dilute the concentrate to form a use composition is water. Generally, a use composition refers to a composition that contacts an article to provide a desired effect. For example, a ware cleaning / rinsing aid composition provided as a use composition may contact an article to clean the article. Additionally, a concentrate or diluted concentrate may be provided as a use composition. For example, a concentrate may be referred to as a use composition when applied to an article without dilution. In many cases, it is anticipated that the concentrate will be diluted to provide a use composition, which is then applied to the article.

[0046] Amine Surfactants The dual-function all-in-one disinfectant rinse composition according to the present disclosure comprises at least one disinfectant amine compound. Certain amines are known to have antimicrobial activity. Thus, various amine-based compounds with antimicrobial activity can be used in the composition of the present disclosure. The term "amine-based" generally refers to any compound having the following formula: [ka] In the formula, the group R 1is a linear or branched, saturated or unsaturated C 4 -C 24 is an alkyl group or H, R 2 and R 3 may be the same or different, including, but not limited to, H, (CH 2 ) 3 NH 2 , (CH 2 ) 3 NHCH 2 COOH, CH 2 COOH, and / or (CH 2 ) 3 N(CH 2 COOH) 2 In some embodiments, R 1 is a saturated carbon chain having less than 24 alkyl groups. 1 is C 4 -C 18 Alkyl group, C 6 -C 18 Alkyl group, C 6 -C 14 alkyl groups, and / or mixtures thereof.

[0047] The use of these amine-based surfactants provides efficiency, excellent antimicrobial effectiveness (see Figures 3-9), rinse aid functionality, low CMC (see Figures 1 and 2), and they can be non-corrosive, low odor, and enzyme compatible (see Figures 10-11).

[0048] In a preferred embodiment, the amine surfactants include N-alkylaminopropyl glycerol, bis(3-aminopropyl)dodecylamine, N-alkylaminopropyl glycerol with chloroacetic acid, 10-16 -alkyltrimethylenediamine reaction products, and / or combinations thereof. Examples include NC with chloroacetic acid. 10-16 -alkyl trimethylene diamine reaction products, etc., may be represented by the following structure: [ka] In the formula, R is a linear or branched, saturated or unsaturated C 4 -C 24 is an alkyl group or H.

[0049] In other embodiments, the compositions of the present disclosure are free of other antimicrobial agents, such as chlorine, oxidizing agents, and quaternary ammonium chlorides.

[0050] An effective amount of an amine surfactant is provided in combination with one or more antifoam agents to provide germicidal efficacy against a broad spectrum of microorganisms, including gram-negative microorganisms such as E. coli, in low temperature dishware. Suitable concentrations of the amine surfactant in the use solution include 1 ppm to about 10,000 ppm, 1 ppm to about 1,000 ppm, 5 ppm to about 400 ppm, 10 ppm to about 400 ppm, 20 ppm to about 400 ppm, 25 ppm to about 400 ppm, 50 ppm to about 400 ppm, 75 ppm to about 400 ppm, or 100 ppm to about 400 ppm. While not intended to be limiting according to the present disclosure, all recited ranges are inclusive of the numbers defining the range and include each integer within the defined range.

[0051] Defoamer In an embodiment of the present disclosure, the composition disclosed herein may include an antifoaming agent. In one embodiment, the composition disclosed herein includes an antifoaming agent. In a preferred embodiment, the antifoaming agent is a nonionic surfactant. In a preferred embodiment, the antifoaming agent is a nonionic alkoxylated surfactant. In another preferred embodiment, the antifoaming agent is represented by the formula RO-(PO) 0-5 (EO) 1-30 (PO) 1-30 , or RO-(PO) 1-30 (EO) 1-30 (PO) 1-30 wherein R is C 8-18Linear or branched alkyl groups, EO=ethylene oxide, PO=propylene oxide.

[0053] Nonionic surfactants are generally characterized by the presence of an organic hydrophobic group and an organic hydrophilic group, and are typically produced by condensation of an organic aliphatic, alkyl aromatic, or polyoxyalkylene hydrophobic compound with a hydrophilic alkali oxide moiety, which is conventionally ethylene oxide or its polyhydration product, polyethylene glycol.Specifically, any hydrophobic compound having a hydroxyl, carboxyl, amino, or amide group with a reactive hydrogen atom can be condensed with ethylene oxide, or its polyhydration additive, or its mixture with an alkoxylene, such as propylene oxide, to form a nonionic surfactant.The length of the hydrophilic polyoxyalkylene moiety condensed with any particular hydrophobic compound can be easily adjusted to produce a water-dispersible or water-soluble compound with the desired degree of balance between hydrophilic and hydrophobic properties.According to the present disclosure, the nonionic surfactant useful in the present composition is a low-foaming nonionic surfactant.Examples of nonionic low-foaming surfactants useful in the present disclosure include the following:

This hydrophobic portion of the molecule has a molecular weight of 1,000 to 4,000. Ethylene oxide is then added to sandwich the hydrophobe between the hydrophilic groups, with the length controlled to comprise about 10% to about 80% by weight of the final molecule. Ethoxylated and propoxylated ethylenediamine compounds are tetrafunctional block copolymers resulting from the sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weights of the propylene oxide hydrotypes range from 500 to 7,000, with the hydrophilic ethylene oxide being added to constitute 10% to 80% by weight of the molecule.

In certain aspects, nonionic surfactants are particularly useful for applications requiring additional antifoaming. In one aspect, it is beneficial that disinfectant and rinsing compositions do not require formulations with nonionic surfactants due to low foaming surface activity. However, in some aspects, nonionic surfactants may be desired to be combined with the composition of the present disclosure (such as included in a detergent formulation that is combined and used together). For example, in certain embodiments, such as food contamination antifoaming applications, nonionic surfactants may be desired to preferably include alcohol alkoxylates and EO / PO block copolymers.

[0090] Useful nonionic surfactants are generally characterized by the presence of an organic hydrophobic group and an organic hydrophilic group, and are typically produced by condensing an organic aliphatic, alkyl aromatic, or polyoxyalkylene hydrophobic compound with a hydrophilic alkaline oxide moiety, which is conventionally ethylene oxide or its polyhydration product, polyethylene glycol.Specifically, any hydrophobic compound having a hydroxyl, carboxyl, amino, or amide group with a reactive hydrogen atom can be condensed with ethylene oxide or its polyhydration additive, or its mixture with an alkoxylene such as propylene oxide to form a nonionic surfactant.The length of the hydrophilic polyoxyalkylene moiety condensed with any particular hydrophobic compound can be easily adjusted to produce a water-dispersible or water-soluble compound with the desired degree of balance between hydrophilic and hydrophobic properties.Useful nonionic surfactants include:

[0091] Block polyoxypropylene-polyoxyethylene polymer compounds based on propylene glycol, ethylene glycol, glycerol, trimethylolpropane, and ethylenediamine as initiator reactive hydrogen compounds. Examples of polymer compounds made from sequential propoxylation and ethoxylation of initiators are poloxamers and ethoxylated and propoxylated ethylenediamines. Poloxamers are bifunctional (two reactive hydrogen) compounds formed by condensing ethylene oxide with a hydrophobic base formed by adding propylene oxide to the two hydroxyl groups of propylene glycol. This hydrophobic portion of the molecule weighs about 1,000 to about 4,000. Ethylene oxide is then added to sandwich the hydrophobe between the hydrophilic groups, with the length controlled to comprise about 10% to about 80% by weight of the final molecule. Ethoxylated and propoxylated ethylenediamine compounds are tetrafunctional block copolymers resulting from the sequential addition of propylene oxide and ethylene oxide to ethylenediamine. The molecular weight of the propylene oxide hydrotype ranges from about 500 to about 7,000, and the hydrophile ethylene oxide is added to constitute from about 10% to about 80% by weight of the molecule.

[0092] Condensation products of one mole of alkylphenol, the alkyl chain of which may be of straight or branched configuration, or of single or double alkyl constituents, containing from about 8 to about 18 carbon atoms, with from about 3 to about 50 moles of ethylene oxide. The alkyl groups may be represented, for example, by diisobutylene, di-amyl, polymerized propylene, iso-octyl, nonyl, and di-nonyl. These surfactants may be polyethylene, polypropylene, and polybutylene oxide condensates of alkylphenols.

The alcohol portion can consist of a mixture of alcohols within the carbon range set forth above, or can consist of an alcohol having a specific number of carbon atoms within this range.

[0094] The condensation products of one mole of a saturated or unsaturated straight or branched chain carboxylic acid having from about 8 to about 18 carbon atoms with from about 6 to about 50 moles of ethylene oxide. The acid portion may consist of a mixture of acids within the carbon atom range defined above, or may consist of an acid having a specific number of carbon atoms within this range.

[0095] In addition to ethoxylated carboxylic acids, commonly referred to as polyethylene glycol esters, other alkanoic acid esters formed by the reaction of glycerides, glycerin, with polyhydric (saccharide or sorbitan / sorbitol) alcohols have application to specific embodiments in this disclosure, particularly indirect food additive applications. All of these ester moieties have one or more reactive hydrogen sites on their molecules that can be subjected to further acylation or ethylene oxide (alkoxide) addition to control the hydrophilicity of these materials. Care must be taken when adding these fatty esters or acylated carbohydrates to compositions of the present disclosure containing amylase and / or lipase enzymes due to possible incompatibilities.

[0096] Examples of non-ionic low foaming surfactants include:

[0097] Compounds from (1) modified, essentially inverted, by adding ethylene oxide to ethylene glycol to provide a hydrophile of specified molecular weight, and then adding propylene oxide to obtain a hydrophobic block on the outside (end) of the molecule. The hydrophobic portion of the molecule has a molecular weight of about 1,000 to about 3,100, and the central hydrophile comprises 10% to about 80% by weight of the final molecule. Similarly, ethoxylated and propoxylated ethylenediamine inverse surfactants are produced by the sequential addition of ethylene oxide and propylene oxide to ethylenediamine. The hydrophobic portion of the molecule has a molecular weight of about 2,100 to about 6,700, with the central hydrophile comprising 10% to 80% by weight of the final molecule.

[0098] Compounds from groups (1), (2), (3) and (4) modified by "capping" or "end blocking" the terminal hydroxy group(s) (of the polyfunctional moiety) to reduce foaming by reaction with hydrophobic small molecules such as propylene oxide, butylene oxide, benzyl chloride; and short chain fatty acids, alcohols or alkyl halides containing 1 to about 5 carbon atoms; and mixtures thereof. Also included are reactants such as thionyl chloride which convert the terminal hydroxy group to a chloride group. Such modifications to the terminal hydroxy group may result in all-block, block-heteric, heteric-block or all-heteric nonionics.

[0153] In one embodiment, the concentrated dual-in-one disinfectant rinse composition is diluted to a use solution concentration of about 0.001% (w / v) to about 10% (w / v), or about 0.001% (w / v) to about 5% (w / v), or about 0.001% (w / v) to about 2% (w / v), or about 0.01% (w / v) to about 1% (w / v). Without being limited to a particular dilution of the concentrated dual-in-one disinfectant rinse composition, in some embodiments, this dilution corresponds to about 0.1 mL to about 10 mL of liquid concentrate per dishwasher cycle (one skilled in the art will appreciate that this further depends on the rinse water capacity of the dishwasher). Without limiting the scope of the present disclosure, the numerical ranges described herein are inclusive of the numbers defining the range and include each integer within the defined range.

[0154] The compositions of the present disclosure can be formulated and sold for use as is, or as a solvent or solid concentrate. If desired, such concentrates can be used at full concentration as a disinfectant rinse composition. However, concentrates are typically diluted with a fluid (e.g., water) to form a dilute phase or use solution thereafter. Preferably, the concentrate forms a single phase prior to such dilution and remains so while stored in the container in which it is sold. When combined with water or other desired dilution fluid at an appropriate dilution level and subjected to gentle agitation (e.g., stirring or pumping the composition), some compositions of the present disclosure form pseudostable dispersions, and other compositions of the present disclosure form clear or metastable solutions or dispersions. When a pseudostable composition is formed, the composition preferably remains pseudostable for a sufficiently long period of time so that the composition can be applied to a surface before the onset of phase separation. The pseudostable state need only last for a few seconds if a suitably rapid application technique such as spraying is used, or if agitation during application is used. The pseudo-stable state desirably lasts for at least 1 minute or more after mixing and while the composition is stored in a suitable container, preferably for 5 minutes or more after mixing. In many cases, regular refilling or recharging of the applicator (e.g., by dipping the applicator into the composition) will provide sufficient agitation to preserve the pseudo-stable state of the composition during application.

[0155] The composition can be applied to the use application or dispensed as a concentrate or use solution during the rinse application, such as the rinse cycle in a warewashing machine, carwash application, for example. In some embodiments, the formation of the use solution can occur from a dual-function integrated sanitizing rinse composition mounted in the washing machine, for example on the dish rack. The dual-function integrated sanitizing rinse composition can be diluted and dispensed from a dispenser mounted on or in the washing machine, or from a separate dispenser mounted separately from but cooperating with the dish machine. For example, in some embodiments, the liquid rinse agent can be injected by incorporating a compatible packaging containing the liquid material into a dispenser adapted to dilute the liquid with water to a final use concentration.

[0156] In other exemplary embodiments, the solid product may be conveniently dispensed by inserting the solid material in a container or without an enclosure into a spray-type dispenser. Such a dispenser cooperates with a warewashing machine in a rinse cycle. When required by the machine, the dispenser directs a spray of water onto a cast solid block of rinse agent, which effectively dissolves a portion of the block to create a concentrated aqueous rinse solution, which is then fed directly into the rinse water to form an aqueous rinse liquid. The aqueous rinse liquid is then contacted with the dishes to cause a thorough rinse. This and other similar dispensers can control the effective concentration of the active moiety in the aqueous rinse liquid by measuring the volume of material dispensed, the actual concentration of the material in the rinse water (electrolyte measured by electrodes), or by measuring the time of spray onto the cast block. In general, the concentration of the active moiety in the aqueous rinse liquid is preferably the same as specified above for the liquid rinse agent. Some other embodiments of spray-type dispensers are disclosed in U.S. Patent Nos. 4,826,661, 4,690,305, 4,687,121, 4,426,362, and Re32,763 and Re32,818, the disclosures of which are incorporated herein by reference. Examples of specific product shapes are shown in FIG. 9 of U.S. Patent Application No. 6,258,765, the disclosures of which are incorporated herein by reference.

[0157] Additional Uses Sanitizing rinse compositions including amine surfactant compositions that provide antimicrobial effectiveness are further suitable for rinsing and wetting applications (including non-sanitizing applications), forming ionic liquids, other antimicrobial and hard surface cleaning applications, forming antimicrobial emulsions and forming microemulsions, dissolving and deodorizing fatty acids including carboxylates as disclosed as suitable anions according to embodiments of the present disclosure, and other enhanced antimicrobial applications (e.g., sanitizers, disinfectants, high level disinfectants for medical devices, etc.).

[0158] All publications and patent applications in this specification are indicative of the level of ordinary skill in the art to which this disclosure pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.

[0159] Manufacturing method The detergent compositions disclosed herein can be formed by combining the components in the weight percentages and proportions disclosed herein. The detergent compositions disclosed herein can be provided as a solid or a use solution is formed during the warewashing process (or other use application).

[0160] In some cases, compositions of the present disclosure are prepared by simple addition of the substances.

[0161] In other embodiments, the compositions according to the present disclosure can be made by mixing the ingredients in an aqueous diluent using commonly available containers and blending equipment. Advantageously, no special manufacturing equipment is required to make the present compositions using amine surfactants and antifoam agents. A preferred method for making the cleaning compositions of the present disclosure includes introducing the ingredients into an agitated production vessel.

[0162] The solid detergent composition disclosed herein can be formed using a solidified matrix and is manufactured using a batch or continuous mixing system. In an exemplary embodiment, a single or twin screw extruder is used to combine and mix one or more components at high shear to form a homogenous mixture. In some embodiments, the processing temperature is below the melting temperature of the components. The processed mixture can be dispensed from the mixer by molding, casting, or other means suitable for the detergent composition to harden into a solid form. The structure of the matrix can be characterized according to its hardness, melting point, material distribution, crystal structure, and other similar properties by methods known in the art. In general, the solid detergent block processed according to the method disclosed herein is substantially homogeneous with respect to the distribution of components throughout its mass and is dimensionally stable.

[0163] Specifically, in the forming process, liquid and solid components are introduced into a final mixing system, and the components are mixed continuously until the components form a substantially homogenous semi-solid mixture with the components distributed throughout its mass. In an exemplary embodiment, the components are mixed in the mixing system for at least approximately 5 seconds. The mixture is then discharged from the mixing system into or through a die or other forming means. The product is then packaged. In an exemplary embodiment, the formed composition begins to harden into a solid form in approximately 1 minute to approximately 3 hours. Specifically, the formed composition begins to harden into a solid form in approximately 1 minute to approximately 2 hours. More specifically, the formed composition begins to harden into a solid form in approximately 1 minute to approximately 20 minutes.

[0164] Compression can use lower pressures compared to conventional pressures used to form tablets or other conventional solid compositions. For example, in one embodiment, the method uses a pressure of about 5000 psi or less on the solid. In certain embodiments, the method uses a pressure of about 3500 psi or less, about 2500 psi or less, about 2000 psi or less, or about 1000 psi or less. In certain embodiments, the method may use a pressure of about 1 to about 1000 psi, about 2 to about 900 psi, about 5 psi to about 800 psi, or about 10 psi to about 700 psi.

[0165] Specifically, in the casting process, liquid and solid components are introduced into a final mixing system, and the components are mixed continuously until the components form a substantially homogenous liquid mixture with the components distributed throughout its mass. In an exemplary embodiment, the components are mixed in the mixing system for at least approximately 60 seconds. Once mixing is complete, the product is transferred to a packaging container where solidification occurs. In an exemplary embodiment, the casting composition begins to harden into a solid form in approximately 1 minute to approximately 3 hours. Specifically, the casting composition begins to harden into a solid form in approximately 1 minute to approximately 2 hours. More specifically, the casting composition begins to harden into a solid form in approximately 1 minute to approximately 20 minutes.

[0166] The term "solid form" means that the hardened composition will not flow under moderate stress or pressure or simple gravity and will substantially retain its shape. The degree of hardness of the solid cast composition can range from that of a relatively dense and hard molten solid product, such as concrete, to a consistency characterized as a hardened paste. In addition, the term "solid" refers to the state of the detergent composition under the expected storage and use conditions of the solid detergent composition. In general, the detergent composition is expected to remain in solid form when exposed to temperatures up to approximately 100°F, specifically above approximately 120°F.

[0167] The resulting solid composition may take any form including, but not limited to, a compressed solid, a cast solid product, an extruded, molded, or formed solid pellet, a block, a tablet, a powder, a granule, flakes, or the formed solid may then be ground or formed into a powder, granule, or flake. In an exemplary embodiment, the extruded pellet material formed by the solidified matrix has a weight of approximately 50 grams to approximately 250 grams, the extruded solid formed by the solidified matrix has a weight of approximately 100 grams or more, and the solid block detergent formed by the solidified matrix has a mass of approximately 1 to approximately 10 kilograms. The solid composition provides a stabilized source of functional material. In some embodiments, the solid composition may be dissolved, for example, in an aqueous or other medium, to generate a concentrated solution and / or a use solution. The solution may be directed to a storage container for subsequent use and / or dilution or may be applied directly to the location of use. Alternatively, the solid alkaline detergent composition is provided in the form of a unit dose, typically provided as a cast solid, extruded pellet, or tablet having a size of approximately 1 gram to approximately 100 grams. In another alternative, a multi-use solid, such as a block or multiple pellets, can be provided and used repeatedly to generate multiple cycles of the aqueous detergent composition.

[0168] All publications and patent applications in this specification are indicative of the level of ordinary skill in the art to which this disclosure pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. EXAMPLES

[0169] The embodiments of the detergent composition disclosed herein are further defined in the following non-limiting examples. Although these examples show specific embodiments of the detergent composition disclosed herein, it should be understood that they are provided merely as examples. From the above discussion and these examples, a person skilled in the art can ascertain the essential features of the detergent composition disclosed herein, and can make various changes and modifications of the embodiments of the detergent composition disclosed herein to adapt it to various applications and conditions without departing from the spirit and scope thereof. Thus, various modifications of the embodiments of the detergent composition disclosed herein will be apparent to a person skilled in the art from the above description, in addition to those shown and described herein. Such modifications are also intended to be included within the scope of the appended claims.

[0170] Example 1 To first determine whether amine surfactants could sufficiently reduce surface tension to function as cleaning / rinsing aids, we tested various concentrations of a single amine surfactant, bis(3-aminopropyl)dodecylamine, or NCs with chloroacetic acid at various pHs. 10-16 The critical micelle concentration (CMC) of either a mixture of amine surfactants, for example an amine mix of -alkyl trimethylene diamine reaction products, was determined.

[0171] All samples were subjected to the tensiometer with concentrations of amine surfactant ranging from 0.001 to 1 wt% in up to 50 mL of DI water. The pH of the solution was adjusted by the addition of bis(3-aminopropyl)dodecylamine, or NC with chloroacetic acid. 10-16- A range of concentrations of the alkyltrimethylenediamine reaction product mix was varied and set at pH of 5, 7, and 9 to determine any possible effects that an acidic, neutral, or basic environment may have on the performance of the amine surfactant.

[0172] As can be seen from Figures 1 and 2, NC with bis(3-aminopropyl)dodecylamine and chloroacetic acid 10-16-Both the alkyltrimethylenediamine reaction products and the mix of chloroacetic acid were able to significantly reduce the surface tension of water at each pH. Bis(3-aminopropyl)dodecylamine was able to reduce the surface tension to about 35 mN / m at pH 5 and 7, and to about 32 mN / m at pH 9 (Figure 1). 10-16 -Alkyl trimethylenediamine reaction product mixes were able to further reduce the surface tension to below 30 mN / m (Figure 2).

[0173] In addition, both compositions show a pH-dependent curve. As can be seen from Figures 1 and 2, by increasing the pH, the NCs with bis(3-aminopropyl)dodecylamine and chloroacetic acid 10-16- Both alkyltrimethylenediamine reaction product mixes showed increased ability to reduce surface tension at reduced concentrations (lower CMC values). Without being bound by theory, it is believed that as the pH shifts from alkaline, e.g., pH 9, to neutral, pH 7, to acidic, e.g., pH 5, the amine surfactants become more cationic (protonated) in nature, resulting in higher electrostatic repulsion and increasing the CMC by an order of magnitude.

[0174] Example 2 To determine the effectiveness of the amine surfactants in various environments as determined by different pH values, the surfactants were tested for antimicrobial effectiveness against E. coli and Staphylococcus aureus. In accordance with AOAC Official Method 960.09 (Germicidal and Detergent Sanitizing Action of Disinfectants), the compositions were tested at concentrations ranging from about 12.5 to about 400 ppm at about pH 5, about pH 7, and about pH 9 (Figures 3-5 for bis(3-aminopropyl)dodecylamine and NC with chloroacetic acid). 10-16 -Alkyl trimethylene diamine reaction product mix (Figures 6-8).

[0175] NC with bis(3-aminopropyl)dodecylamine and chloroacetic acid 10-16 There is a pH-dependent effect on the log reduction of bacteria as seen in both the mix of NC-alkyltrimethylenediamine reaction products. At a pH of 5, the NC-chloroacetic acid and 10-16- Only the alkyltrimethylenediamine reaction product mix was able to achieve a 5-log reduction in both E. coli and Staphylococcus aureus at the highest concentration tested (Figures 3 and 6). However, as the pH was increased from 5 to 7 to 9, the bis(3-aminopropyl)dodecylamine and NC with chloroacetic acid showed no significant difference. 10-16 -The efficacy of both alkyltrimethylenediamine reaction product mixes was increased for both E. coli and Staphylococcus aureus.

[0176] When tested for efficacy at pH 7 (Figures 4 and 7), bis(3-aminopropyl)dodecylamine and NCs with chloroacetic acid 10-16 Both the 1- and 2-alkyltrimethylenediamine reaction product mixes were able to achieve a 5-log reduction against E. coli up to a concentration of 50 ppm. However, against Staphylococcus aureus, bis(3-aminopropyl)dodecylamine required concentrations of 75-100 ppm to achieve a 5-log reduction (Figure 4), whereas NC with chloroacetic acid was significantly higher than 100 ppm. 10-16 At pH 9, bis(3-aminopropyl)dodecylamine achieved a 5 log reduction for both E. coli and Staphylococcus aureus at concentrations between 12.5 and 25 ppm (Figure 5), whereas a mix of NC-alkyltrimethylenediamine reaction products with chloroacetic acid required concentrations between 50 and 75 ppm (Figure 7). 10-16 -Alkyl trimethylenediamine reaction product mixes required concentrations of 25-50 ppm for a 5 log reduction of Staphylococcus aureus and 12.5-25 ppm for E. coli (Figure 8).

[0177] As can be seen from these results, both surfactant compositions show a pH-dependent response of microbial effectiveness, with the more basic the composition, the better it performs. As the pH becomes more neutral and slightly acidic (pH 5), the effectiveness decreases, and higher concentrations are required to achieve at least a 5 log reduction in bacteria. This is consistent with the increasing effectiveness of reducing surface tension with increasing pH, as seen in Example 1.

[0178] Example 3 The ability of the antifoam agents to control the foam profile of the surfactant was also tested. Since bis(3-aminopropyl)dodecylamine showed good antimicrobial properties at 25 ppm, pH 9 in Example 2 against both E. coli and Staphylococcus aureus, it was tested at 25 ppm, pH 8.5, over different ratios with alkoxylated alkyl alcohol nonionic antifoam agents at 100 or 120° F. using the Glewwe foam test.

[0179] As shown in Table 2, fatty alcohol alkoxylate (alkoxylated alkyl alcohol nonionic surfactant) defoamers can effectively suppress bis(3-aminopropyl)dodecylamine foaming and even defoam food soils in combination with amine-based germicidal surfactants. Foam heights never exceeded the 3 inch maximum height required for passing the test by the Glewwe test, and generally there was no or only slight foaming. Even at a 3:1 surfactant to defoamer ratio, fatty alcohol alkoxylate was sufficient to keep the foam low for machine cleaning. At lower ratios, such as 2:1 or 1:1 surfactant to defoamer, foam levels were better maintained at low to no foam levels. [Table 4]

[0180] Example 4 As other examples show amine surfactants with pH sensitivity in their properties, including antimicrobial efficacy, it was unclear how mixing them with antifoam agents would affect their antimicrobial efficacy.Following the same protocol as in Example 2, different concentrations and ratios of bis(3-aminopropyl)dodecylamine and fatty alcohol alkoxylate (alkoxylated alkyl alcohol nonionic surfactant) antifoam agents were tested at pH 9 (Figure 9).

[0181] As shown in Figure 9, surfactant and antifoam blends were able to achieve at least a 5 log reduction in both E. coli and Staphylococcus aureus at concentrations below 60 ppm when the surfactant to antifoam ratio was 2:1. However, at a 1:1 ratio with 50 ppm bis(3-aminopropyl)dodecylamine, only a 2.4 log reduction was achieved for Staphylococcus aureus and a 3.7 log reduction for E. coli. Thus, lower concentrations of amine surfactant require higher surfactant to antifoam ratios to achieve antimicrobial efficacy.

[0182] Example 5 The suitability of the disclosed compositions was further tested with other compounds such as enzymes. Initial tests were performed using mild detergents, enzymes, and / or amine surfactants, either individually or in combination, as shown in FIG. 10. The ware was washed for 7 cycles and the remaining protein film was evaluated, with 1 being the best cleaning power and 5 being the worst. As shown in FIG. 10, the bis(3-aminopropyl)dodecylamine-based rinse aid, alone or in combination with a mild pH detergent, performed poorly in removing protein. Adding about 10 ppm of protease gave a slight improvement when combined with detergent and amine surfactant. However, the improvement was less than enzyme and detergent alone, which had the best cleaning power among the different combinations. Thus, at neutral pH, even with enzyme, amine surfactants perform worse than detergent alone or detergent and enzyme.

[0183] However, as shown in the previous examples, amine surfactants are pH-dependent in their properties, which may be due to their protonation at lower pH values. Also, Example 2 showed that at higher pH values, the antimicrobial effect of amine surfactants is higher, and Example 1 showed that at more basic pH, the critical micelle concentration of bis(3-aminopropyl)dodecylamine is lower. Therefore, to preserve their antimicrobial properties, amine surfactants were tested in increasing pH detergents combined with enzymes for rinse aid properties against proteinaceous soils.

[0184] As shown in Figure 11, increasing the pH from about pH 9 to pH 11 with about 10 ppm of enzyme (protease at pH 9 or less, endopeptidase at pH 10 or more) increases the ability to remove protein. Furthermore, at a pH of about 10 to 10.5, the ability of detergent, endopeptidase, and bis(3-aminopropyl)dodecylamine prevented nearly all film formation with a score of 1. Taken together with the previous examples, to maintain good antimicrobial efficacy and other properties, the pH should be slightly basic and greater than about 25 ppm of amine surfactant should be included in the compositions of the present disclosure.

[0185] The present invention being thus described, it will be apparent that the same may be varied in many ways. Such variations should not be regarded as departures from the spirit and scope of the disclosure, and all such modifications are intended to be included within the scope of the following claims. The above specification provides an explanation of the manufacture and use of the disclosed compositions and methods. Since many embodiments may be made without departing from the spirit and scope of the disclosure, the disclosure resides in the claims.
