Abstract
Description
[Technical Field]
[0001] The present invention relates to automatic dishwashing compositions comprising structural polypeptides, methods for machine cleaning of dishes, the use of structural polypeptides in automatic dishwashing compositions, and the use of automatic dishwashing compositions for treating soiled dishes. [Background technology]
[0002] In a typical mechanical dishwashing process (automated dishwashing, abbreviated ADW) for home and commercial use, including I&I (industrial and institutional) applications, the objects to be washed, such as food-soiled dishes or utensils, undergo numerous treatments in a series of zones and / or cycles. The washing process generally consists of several consecutive steps, including the actual washing operation. In the washing zone, the soiled dishes are typically sprayed with a liquid detergent at a pressure sufficient to loosen the soil present on the dishes. The washing zone may be preceded by at least one pretreatment zone, e.g., to mechanically remove loosely attached food residues, in which case the dishes are also contacted with water or another liquid cleaning medium. The actual washing process is typically followed by at least one rinsing step and a drying step for the washed dishes. These operations are performed in a more or less automated fashion, with the central device being the dishwasher, which performs at least the washing step, typically followed by a rinsing step and / or a drying step.
[0003] In a domestic dishwasher, soiled dishes are typically washed in a single chamber, with the aforementioned treatment steps progressing sequentially according to a controlled program. Fresh water passes through a water softener unit into a pump well and is sprayed onto the dishes by a moving spray arm. Rinse-water-insoluble materials are filtered within the pump well. During the first wash cycle, a cleaning composition, typically alkaline, is added to the liquid wash medium, heated to a set temperature, and sprayed onto the dishes. During the rinse cycle, a rinse builder is added to the treatment solution to reduce surface tension, allowing the treatment solution to flow more easily from the dishes. After the final rinse cycle, the dishes are dried. The ingredients used in the ADW process, such as water treatment agents, cleaning actives, and rinse builders, can be used either in the form of individual components or in multi-compartment formulations.
[0004] Commercial dishwashers are basically comprised of fixed bath tanks, each of which sprays or sprays a primarily aqueous cleaning solution onto dishes, e.g., dishes on a conveyor belt pass through these tanks, and the used cleaning solution returns to the bath tanks. Water enters the last bath tank, flows stepwise through overflows to all other tanks, and is discharged from the machine by overflow from the first tank. The application of the cleaning solution, which is typically highly alkaline, is carried out, for example, by dedicated nozzles or a dedicated spray system, usually located in the center of the machine.
[0005] Current automatic dishwashing compositions are complex formulations containing many different ingredients, such as sequestrants / dispersants, nonionic surfactants, enzymes, bleaching agents, corrosion inhibitors, thickeners, etc. These can be dispensed into the dishwasher individually or in the form of a mixture of two or more components. Many different forms of ADW detergent compositions are known in the art. Possible forms include powders, granules, gels, pastes, liquids, tablets (tablets), capsules (capsules), water-soluble pouches (liquid tablets), water-soluble containers, etc. Water-soluble film-forming polymers, especially those with specific release characteristics, can be used as sheaths or coatings that contain the entire dishwashing composition or at least some of its ingredients. The capsules or containers can be single-compartment or multi-compartment. The ADW composition may also be a system. Thus, ingredients that have stability issues, for example, because they are hygroscopic or incompatible with other ingredients, can be used in complex dishwashing compositions. Thus, the ADW composition may also include a mixture of two or more forms, for example, a gel component and a powder component.
[0006] In the home, so-called "single-use" products, which contain a quantity of dishwashing composition sufficient for one dishwashing operation, are common. Gel formulations are also very attractive to consumers because they are easier to dispense than low-viscosity products and are aesthetically pleasing, especially in the form of clear or translucent gels.
[0007] ADW compositions must meet complex requirements, including cleaning soiled dishes well, leaving them shiny and streak-free, not damaging them even after repeated washing, providing special surface protection, being versatile for different types of surfaces and soils, and allowing for good drying of washed items. Staining and filming on dishes, especially glassware and cutlery, are essential criteria for judging the performance of dishwashing formulations. Staining refers to scattered residues on glassware that form when water droplets evaporate, leaving behind dissolved solids. Filming refers to widespread, uniform deposition on the glass surface. ADW formulations should be able to inhibit both inorganic and organic filming. Inorganic filming is primarily caused by calcium and magnesium salts in water and the builders used in standard dishwashing compositions. Organic filming is particularly caused by soil components from the rinse liquor, such as protein, starch, and fat deposits. There is also growing interest in using environmentally friendly and / or bio-based ingredients in ADW compositions.
[0008] There continues to be a need for automatic dishwashing compositions that have at least one, and preferably several, of the following properties: good surface protection, improved stain and film formation even with hard water, and good drying. The application of additional properties of the ADW composition should not adversely affect cleaning effectiveness, among other things. The ingredients contained in the ADW composition should be non-toxic, non-hazardous to the environment, and safe for humans and animals. It should be possible to provide the product in the form of a gel.
[0009] Surprisingly, it has been found that structural polypeptides such as silk polypeptides are suitable for the formulation of ADW compositions with improved properties.Silk polypeptides are polymers that exhibit excellent properties, and can provide ADW formulations with various advantages, including good surface protection, improved stain and film formation, and good drying properties.Structural polypeptides such as silk polypeptides are biocompatible, non-toxic, and environmentally friendly, and are suitable for the formulation of machine dishwashing compositions in all forms, such as gels and other forms.

[0014] This summary of the invention does not necessarily describe all features of the invention. Other embodiments will become apparent by consideration of the following detailed description.
[0015] Before describing the present invention in detail below, it is to be understood that this invention is not limited to the particular methodology, procedures, and reagents described herein, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention, which is limited only by the appended claims. Unless otherwise defined, all technical and scientific terms used herein are commonly understood by those of ordinary skill in the art. has the same meaning as that given in the preceding sentence.
[0016] Preferably, the terms used herein are defined as set forth in "A multilingual glossary of biotechnological terms: (IUPAC Recommendations)," Leuenberger, HGW, Nagel, B. and Koelbl, H. eds. (1995), Helvetica Chimica Acta, CH-4010 Basel, Switzerland.
[0017] Several documents are cited throughout the text of this specification. Each document cited herein (including all patents, patent applications, scientific publications, manufacturer's specifications, instructions, sequence entries with GenBank accession numbers, etc.), whether supra or infra, is incorporated herein by reference in its entirety. Nothing stated herein should be construed as an admission that the present invention is not entitled to antedate such disclosure by virtue of prior invention.
[0018] The components of the present invention are described below. These elements are listed with specific embodiments. However, it should be understood that they can be combined in any manner and in any number to create additional embodiments. The various described examples and preferred embodiments should not be interpreted as limiting the invention to only the explicitly described embodiments. The description should be understood to support and encompass embodiments that combine the explicitly described embodiments with any number of the disclosed and / or preferred elements. Furthermore, any permutation and combination of all elements described in this application should be considered disclosed by the description of this application unless the context indicates otherwise.
[0019] The term "dishwashing composition," as used herein, refers to a composition adapted for washing dishes with water. The term "dishwashing composition" encompasses manual dishwashing compositions or automatic dishwashing compositions.
[0020] Structural polypeptides, such as silk polypeptides, are particularly advantageous for use in automatic dishwashing compositions that must meet a complex property profile. The automatic dishwashing compositions of the present invention have at least one, and preferably two, three, or more, of the following advantages: structural polypeptides, particularly silk polypeptides, are polymers that exhibit excellent application properties and can provide various benefits to ADW formulations. The compositions of the present invention can effectively reduce staining and film formation. After the washing process, tableware, particularly glassware and cutlery, have a good luster and exhibit significantly fewer water marks, soils, and / or stains compared to conventional products using the prior art. The compositions exhibit good cleaning even in hard water and heavily soiled dishes. They are suitable for improving stain removal and / or preventing re-soiling of dishes. The compositions of the present invention are suitable for providing surface protection to dishes. In particular, they do not corrode the surface of glassware, even with repeated use, and in particular do not cause clouding, stains, scratches, or iridescence of the glass surface. The compositions of the present invention are suitable for imparting low surface tension to dishes. When dishes, particularly glass dishes, are washed in a dishwasher using the automatic dishwashing composition of the present invention, the contact angle of deionized water on the washed items is significantly reduced compared to conventional products from the prior art. Dishes treated with the compositions of the present invention exhibit improved drying properties. This composition effectively works even with very low application rates. The structural proteins, particularly silk proteins, contained in the ADW compositions of the present invention are biocompatible, non-toxic, non-harmful to the environment, and safe for humans and animals. Silk proteins, in particular, are made exclusively from renewable resources, are 100% biodegradable, and do not contain microplastics. In terms of regulatory and environmental issues, this may be more advantageous than compositions based on conventional ingredients. Structural proteins, particularly silk proteins, are suitable for use in phosphate-free formulations.Structural proteins, particularly silk proteins, are suitable for use in a wide variety of different forms, such as gels, aqueous solutions, and organic solvents.This composition is particularly suitable for single-dose products.
[0021] Without wishing to be bound by any theory, it is believed that the structural polypeptides used, particularly silk polypeptides, are suitable for surface modification of dishware, imparting improved properties to the dishware. The structural polypeptides adhere to the surface, thus allowing for efficient cleaning and drainage of the wash solution and / or rinse water. This helps prevent the formation of water droplets, which can lead to the buildup of residue on the dishware surface and the formation of visible stains or streaks during drying. Surprisingly, this surface modification can be affected by delivering the structural polypeptides into the main wash solution along with the remaining cleaning composition, allowing them to remain on the surface of the dishware during and even after the rinse cycle. Thus, the use of structural polypeptides in the ADW composition allows for good drainage during the rinse phase, maintaining protection against surface damage and recontamination. This reduces or eliminates the need for a separate rinse aid product.
[0022] For the purposes of this application, the term dishware encompasses any type of soiled item that is subject to the automatic cleaning process in a dishwasher. Thus, the term dishware encompasses dishware (tableware), cookware, cutlery, kitchen utensils, and other items for practical and decorative purposes.
[0023] The automatic dishwashing compositions of the present invention may be in any form, such as powder, granules, gel, paste, liquid, tablet, capsule, water-soluble pouch, water-soluble container, etc. In particular, a water-soluble film-forming polymer having special cleaning properties may be used as a sheath or coating for the entire dishwashing composition or at least one of its components. The capsule or container may be a single compartment or a multi-compartment system.
[0024] In a preferred embodiment, the automatic dishwashing composition is in the form of a gel formulation. In particular, the automatic dishwashing composition may be in the form of a gel, or the automatic dishwashing composition may be a multi-compartment formulation containing the structural polypeptide in the form of a gel or in solution. Preferred solvents are water, at least partially water-miscible organic solvents, and mixtures thereof. In a particular embodiment, the automatic dishwashing composition is a multi-compartment formulation containing the structural polypeptide in the form of a hydrogel.
[0025] In a preferred embodiment, the automatic dishwashing composition is in the form of a single dose product (ie, containing the correct amount of dishwashing composition sufficient for one dishwashing operation).
[0026] In a more preferred embodiment, the automatic dishwashing composition is in the form of a unit dose. Unit dose products include tablets, capsules, sachets, pouches, containers, etc. The automatic dishwashing composition of the present invention is preferably in the form of a multi-compartment formulation. A multi-compartment formulation (including a multi-chamber or multi-functional formulation / system) is a water-soluble multi-compartment pack made of a water-soluble polymer, for example, in the form of a film or molded body, having one, two, three, four, five, six, or more than six individual sections. Preferred for use in the present invention are tablets (including tablets, capsules, sachets, and pouches) coated or packaged with a water-soluble polymer film, and containers made of water-soluble polymers. Each section of the multi-compartment formulation may be independently filled with powder, granules, gel, paste, liquid, or a combination thereof.
[0027] In a possible embodiment, the structural polypeptide a) can be distributed in separate compartments of a multi-compartment formulation.
[0028] The automatic dishwashing composition of the present invention is preferably free of phosphoric acid. "Free of phosphoric acid" is understood herein to mean that the composition contains less than 1% by weight of phosphoric acid, preferably less than 0.1% by weight, and in particular less than 0.05% by weight of phosphoric acid, based on the total weight of the composition. "Free of phosphoric acid" means that the automatic dishwashing composition does not contain alkali metal orthophosphates and alkali metal polyphosphates, in particular pentasodium triphosphate (sodium tripolyphosphate, STPP).
[0029] Component a) (Structural Polypeptide) In the present invention, the terms "polypeptide" and "protein" are used interchangeably and refer to a long chain of peptide-linked amino acids, e.g., at least 30 amino acids in length.
[0030] In the present invention, the term "structural polypeptide" refers to any polypeptide comprising repeating units (repeated components) of amino acids. The structural polypeptide preferably has the ability to undergo polypeptide assembly. In particular, the structural polypeptide is capable of forming protein complexes (aggregates) in a formulation, e.g., a hydrogel in an aqueous formulation. The structural polypeptide may be selected from the group consisting of silk polypeptides (including fibroin), keratin, collagen, and elastin, or variants or combinations thereof. The structural polypeptide is particularly a recombinant or synthetic structural polypeptide. The structural polypeptide is preferably a silk polypeptide (recombinant or synthetic), such as a spider silk polypeptide (recombinant or synthetic). Exemplary methods for producing silk polypeptides are described in WO2006 / 008163 and WO2011 / 120690.
[0031] In the present invention, the term "silk polypeptide" refers to a polypeptide that exhibits a highly unusual amino acid composition compared to other polypeptides. In particular, silk polypeptides are highly enriched in hydrophobic amino acids such as glycine or alanine. Furthermore, silk polypeptides contain highly repetitive amino acid sequences or repeating units (repeat units, modules), particularly in their large core domains. DNA analysis has shown that all silk polypeptides are chains of repeating units that further contain a limited set of distinct, significantly shorter peptide motifs. The terms "peptide motif" and "consensus sequence" can be used interchangeably in the present invention. In general, silk consensus sequences can be classified into four major categories: GPGXX, GGX, Ax or (GA)n, and spacers. These peptide motif categories in silk polypeptides have been assigned structural roles. For example, the GPGXX motif has been suggested to be involved in a β-turn helix, likely providing elasticity. The GGX motif is known to be involved in a glycine-rich 31-helix. Both GPGXX and GGX motifs are thought to be involved in the formation of an amorphous matrix that connects crystalline regions and thereby provides the fiber's elasticity. The alanine-rich motifs, typically containing 6-9 residues, have been found to form crystalline beta sheets. The spacers, typically containing charged groups, separate the repeating peptide motifs into clusters. Silk polypeptides are capable of polypeptide assembly.
[0032] Fibroin is a structural polypeptide and a silk polypeptide in the present invention.
[0033] The silk polypeptide is in particular a recombinant or synthetic silk polypeptide.
[0034] Preferably, the (recombinant or synthetic) silk polypeptide is a (recombinant or synthetic) spider silk polypeptide. It is a silk polypeptide derived from silkworms.
[0035] The term "polypeptide assembly," as used herein, refers to the process by which a pre-existing disordered state of polypeptides forms an organized structure or pattern as a result of specific local interactions between the polypeptides themselves (e.g., van der Waals forces, hydrophobic interactions, hydrogen bonds, and / or salt bridges, etc.) without any external action or trigger, although external factors may affect the rate and nature of polypeptide assembly. This specifically means that when two or more disordered and / or unfolded polypeptides come into contact, they interact with each other, resulting in the formation of a three-dimensional structure. The change from a disordered state to an organized structure or pattern during self-polypeptide assembly is characterized by a transition from a fluid state to a gel-like and / or solid state and a concomitant increase in viscosity. The transition from a fluid state to a gel-like state can be monitored, for example, by optical or rheological measurements.
[0036] Preferably, the structural polypeptides that assemble the polypeptides are (recombinant or synthetic) silk polypeptides, such as (recombinant or synthetic) spider-derived silk polypeptides.
[0037] The term "polypeptide aggregate" (or polypeptide complex), as used herein, refers to a polypeptide structure formed as a result of polypeptide self-assembly. During polypeptide self-assembly, multiple copies / units of a polypeptide self-assemble into bodies or clumps without any external action or trigger, although external factors may affect the rate and nature of self-polypeptide assembly. In polypeptide aggregates, different polypeptides are linked or bonded to each other through covalent bonds (e.g., disulfide bridges) and / or non-covalent interactions (e.g., van der Waals forces, hydrophobic interactions, hydrogen bonds, and / or salt bridges). It is clear that a polypeptide aggregate encompasses at least two polypeptides. In the present invention, the self-assembly of (recombinant or / synthetic) silk polypeptides is described. During the self-assembly of silk polypeptides, silk polypeptide aggregates (silk polypeptide complexes) are formed.
[0038] The term "hydrogel," as used herein, refers to a structure formed when the concentration of structural polypeptides is high enough to immobilize the liquid components and establish a continuous network. The network is preferably formed by a polypeptide assembly of the structural polypeptides, which provides the basis for the hydrogel. In particular, a hydrogel is a hydrophilic polymer network of structural polypeptides. The network is stabilized by chemical and / or physical interactions between the structural polypeptides. The network is dispersed throughout an immobilized liquid phase. The hydrogel's hydrophilicity and stability allow it to penetrate and absorb water (swell) without dissolving, thus maintaining its three-dimensional (3D) structure and function.
[0039] A preferred embodiment of the hydrogel is a flowable hydrogel. As used herein, the term "flowable hydrogel" refers to a hydrogel that can flow, especially when subjected to gravity. A flowable hydrogel is in a liquid state (i.e., it is not yet self-supporting, in the sense that it cannot maintain an assigned shape without a shape-stabilizing coating). The compliance of a hydrogel can be easily determined by one skilled in the art, for example, by rheological or viscosity measurements. Compliance measurements are preferably performed under standard conditions (20°C). A method for determining the viscosity of a gel is described in detail below.
[0040] In other words, the hydrogel is a non-flowable hydrogel. This hydrogel can be converted into a flowable hydrogel by shear-thinning. The same applies to solid forms. This also applies to the structural polypeptide of the present invention, which is
[0041] Preferably, the structural polypeptide used in accordance with the present invention is in the form of a hydrogel. More preferably, the structural polypeptide in the form of a hydrogel is a silk polypeptide. In particular, the structural polypeptide in the form of a hydrogel is a recombinant or synthetic silk polypeptide.
[0042] Preferably, the structural polypeptide used in accordance with the present invention is in the form of a flowable hydrogel. More preferably, the structural polypeptide in the form of a flowable hydrogel is a silk polypeptide. In particular, the structural polypeptide in the form of a flowable hydrogel is a recombinant or synthetic silk polypeptide.
[0043] The hydrogel is hereinafter also referred to as silk protein gel or silk gel. The production of the hydrogel is described, for example, in WO2020035361, WO2022258500 or WO2022258499.
[0044] In a preferred embodiment, the automatic dishwashing compositions according to the present invention comprise structural polypeptides capable of forming polypeptide aggregates, in particular, said polypeptides having the potential to assemble into fibrillar structures (i.e., fibrillar aggregates (complexes) of structural polypeptides).
[0045] Preferably, the structural polypeptide is selected from silk polypeptides, keratin, collagen, elastin, and combinations thereof. In some embodiments, the silk polypeptide is fibroin. In particular, the structural polypeptide is a recombinant polypeptide, such as a recombinant silk polypeptide, keratin, collagen, or elastin.
[0046] More preferably, the structural polypeptide is a silk polypeptide, especially a recombinant silk polypeptide.
[0047] In a preferred embodiment, the (recombinant) silk polypeptide is a spider-derived silk polypeptide. Suitable spider-derived silk polypeptides are major ampullate silk polypeptides, such as dragline silk polypeptides, minor ampullate silk polypeptides, or flagelliform silk polypeptides of orb-web spiders. In particular, the silk polypeptide is a spider-derived silk polypeptide, more preferably a recombinant spider-derived silk polypeptide.
[0048] In a preferred embodiment, the silk polypeptide comprises or consists of 25 to 4000 amino acids, more preferably 30 to 1500 amino acids, particularly 35 to 1200 amino acids, and in a particular embodiment, the silk polypeptide comprises or consists of 60 to 600 amino acids.
[0049] In a preferred embodiment, the silk polypeptide consists of a single unit of amino acids. In this embodiment, the protein chain is defined as having no units (at least two) of the same or similar sequence motif. In this embodiment, the silk polypeptide preferably consists of 25 to 250 amino acids, particularly 30 to 150 amino acids.
[0050] In another preferred embodiment, the silk polypeptide comprises at least two repeating units. A silk polypeptide is a polypeptide having an amino acid sequence that comprises or consists of 50% of multiple copies of repeat units. The amino acid sequence may be composed of 100% of multiple repeat units. More preferably, the silk polypeptide is a polypeptide having an amino acid sequence that comprises or consists of at least 50%, particularly at least 60%, particularly at least 65%, particularly at least 70%, particularly at least 75%, particularly at least 80%, particularly at least 85%, particularly at least 90%, particularly at least 95%, or particularly at least 99% of multiple copies of repeat units. The repeat units may be identical or different.
[0051] When the amino acid sequence of the silk polypeptide is a polypeptide comprising or consisting of multiple copies of a repeat unit, each repeat unit preferably comprises or consists of 25 to 250 amino acids, in particular 30 to 150 amino acids.
[0052] When the amino acid sequence of the silk polypeptide is a polypeptide comprising or consisting of multiple copies of a repeat unit, the total number of amino acids in all repeat units is preferably in the range of 25 to 3000 amino acids, more preferably 30 to 1500 amino acids, particularly 35 to 1200 amino acids, and especially 60 to 600 amino acids.
[0053] In a preferred embodiment, the silk polypeptide comprises or consists of at least two identical repeating units. For example, the silk polypeptide comprises 2 to 96 repeating units, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95 or 96 repeating units.
[0054] In particular, the repeat unit is a group consisting of module C having the amino acid sequence of SEQ ID NO: 1 (GSSAAAAAAAASGPGGYGPENQGPSGPGGYGPGGP) or a variant thereof, module C having the amino acid sequence of SEQ ID NO: 2 (GSSAAAAAAAASGPGGYGPENQGPCGPGGYGPGGP) or a variant thereof Cys , module C having the amino acid sequence of SEQ ID NO: 3 (GSSAAAAAAAASGPGGYGPKNQGPSGPGGYGPGGP) or a variant thereof Lys are independently selected from the group consisting of:
[0055] Module C Cys (SEQ ID NO: 2) is a variant of module C (SEQ ID NO: 1). In this module, the 25th amino acid, Ser, is replaced by the amino acid Cys. Module C Lys (SEQ ID NO: 3) is also a variant of module C (SEQ ID NO: 1), in which the 20th amino acid, Glu, is replaced by the amino acid Lys.
[0056] A module C variant differs from the reference module C from which it is derived by up to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 amino acid changes in amino acid sequence (i.e., substitutions, additions, insertions, deletions, N-terminal truncations, and / or C-terminal truncations).

[0174] In all the above aspects / embodiments, the structural polypeptide, in particular the silk polypeptide, is preferably present in the (automatic / manual) dishwashing composition in the form of a gel, in particular a hydrogel.
[0175] Various modifications and variations of this invention will be apparent to those skilled in the art without departing from the scope of the invention. Although the invention has been described in connection with specific preferred embodiments, it should be understood that the invention as claimed should not be unduly limited to such specific embodiments. Indeed, various modifications of the described modes for carrying out the invention that are obvious to those skilled in the relevant fields are intended to be covered by the present invention.

[0207] II) Application examples II.1) Cleaning Effect of Automatic Dishwasher Gel Detergency measurements were performed based on the IKW method "Recommendations for the Quality Assessment of Detergency Performance of Dishwasher Detergents (Part B, Update 2015)." According to the IKW method, there are eight types of soils, divided into four classes. Corresponding to the bleach, alkali, and enzyme dishwashing detergent formulations, at least one soil type from each of the four soil classes (bleachable, persistent / alkali-sensitive, starch-containing / amylase-sensitive, and protein-containing / protease-sensitive) was used for testing. Eight soil types were selected, with at least one soil type selected from each class (see Table 1 below). After each wash cycle, a visual evaluation was performed using a score from 0 to 10, depending on the degree of cleaning and the type of soil. A higher score indicates better cleaning effectiveness. IKW test conditions Dishwasher: Bosch Program: Eco 50° Cycle Water hardness: 21°GH (general hardness) Dosage: 25g of gel formulation in the main cycle The test results are shown in Table 1. [Table 1] The IKW test demonstrates the high level of cleaning performance of the tested dishwashing detergents. The presence of structural proteins does not have a negative effect on cleaning performance. II.2 Gloss test The dishes were evaluated and scored for staining and filming levels as follows: 5 - Strongest staining / filming 4 - Very strong staining / filming 3-Severe staining / filming 2- Slight staining / filming 1 stain / no film formation Stain / film formation test conditions Dishwasher: Bosch Program: Eco 50° Cycle Water hardness: 21°GH The results are shown in Table 2 below. [Table 2] Stain = staining, film formation = film formation These tests demonstrate that automatic dishwashing formulations according to the present invention containing silk protein as a structural protein have superior stain / filming performance.
[0208] Example 2: Test Method: Comparative rinse aid testing of automatic dishwashing detergents according to Fresenius Standard Method 03 2016. Test conditions: The washing machine used was a Miele GSL 2. The program was set to 50°C for 8 minutes with a 65°C rinse cycle. The water hardness was 9±1°dH. Dosage: 20 ppm in cleaning solution. No rinse builder was used. The cumulative number of cycles was 3. Ballast soil: 50 g of ballast soil was used per cycle with the ingredients ketchup, milk, starch, fat, egg yolk, benzoic acid and water. Loading the dishwasher: The dishwasher was loaded with six blue plastic melamine dishes, three black glass dishes (Alcolock), four long drink glasses (Shot Paris 79), and four juice glasses (Shot Paris 12). Samples used: IEC 60436-Typ D (detergent, batch number CFT-GSM D~020 rev.2020 CFT), hereafter abbreviated as IEC-D, was used as the detergent. Test procedure: Glasses and plates were placed in a dishwasher and treated with Neo-Disher and citric acid, followed by two cycles with the test detergent. The dishwasher was modified to prevent commercial ion exchangers from operating. The machine was supplied with a fixed amount of water via an external tank. The rinse builder dispenser was emptied. If rinse builder was used in the test, it was added manually with a pipette. 50g of ballast soil was added at the start of the wash cycle. After the program finished, the full door was left closed for an additional 10 minutes. The door was then fully opened and the dishwasher rack was completely removed from the machine. Evaluation began after 20 minutes. After the dishes were completely dried, the rinse aid effectiveness was visually evaluated in a "black box" under defined lighting conditions. Dried water droplets, streaks, residue or cloudy film on dishes and cutlery were evaluated. Three replicates (cumulative) were tested for each product and the arithmetic mean was calculated. result: 1. Visual assessment of water and salt stains Blue melamine dishes and Alcolock glass dishes were treated under the test conditions and procedures described above. Briefly, the plates were placed in a dishwasher with ballast soil and either (i) cleaning agent (IEC-D) or (ii) cleaning agent combined with silk gel (IEC-D) was added. After three (cumulative) wash cycles for each product, visual grading was performed for salt and water stains. Arithmetic means were calculated. Visual grading of stains was performed by an independent laboratory (Fresenius Institute) on an 8-point scale for water and salt stains, as shown below: 8=No stains or streaks, 7 = Very slight streaks and / or very minor stains; 6 = slight streaks and / or small stains; 5 = slight or moderate streaks and / or medium-sized stains; 4 = Some medium streaks and / or medium-sized stains; 3 = moderate streaks and / or several large stains; 2 = several large streaks and / or large stains; 1 = large streaks and / or numerous large stains; 0 = Very large streaks and / or numerous large stains. The arithmetic mean of blue melamine dishes washed with IEC-D was calculated to be 3.8, while that of IEC-D + spider silk was 5.6. The arithmetic mean of the Alcoloc glass dish washed with IEC-D was calculated to be 5.6, while the arithmetic mean of the dish washed with IEC-D plus spider silk was 6.0. In summary, a reduction in the number of stains was observed when blue melamine dishes and Alcolock glass dishes were washed with IEC-D + silk gel compared to washing with IEC-D alone (Table 3). [Table 3] Table 3: Comparative results of cleaning detergent testing of detergents for automatic dishwashers according to Fresenius Standard Method 03 2016. Detergent IEC 60436-Typ D (abbreviated here as IEC-D) was tested with and without silk gel. The combinations were compared in terms of the reduction of stain formation on plates after three repeated wash cycles (cycle 1=A, cycle 2=B, cycle 3=C) in a washing machine according to Fresenius Standard Method 03 2016 SOP M 2422 Version 2. 2. Digital Image Analysis The tested drinking glasses were visually evaluated and then measured by digital image analysis. For this, each glass was fixed in a rack and illuminated with a specific light source. During the digital measurement, the glass was rotated 360 degrees. The result was a flat image. Special software made it possible to calculate the number, size and intensity of stains. The bottom and top of the glass were excluded. The classification of the results was carried out using the following grading: 5 = very large stain, 4=large stain, 3 = medium size stain; 2 = small stains, and 1 = very small stain. When glassware was treated with detergent IEC-D-Silk Gel, medium-sized stains were detected on the glass surface after three consecutive washing cycles. For glassware washed with detergent IEC-D+Silk Gel, only small-sized stains were detected on the glass surface after three consecutive washing cycles. The stain formation rating was 3 for the glass samples treated with the detergent IEC-D-Silk Gel and 2 for the glass samples treated with the detergent and rinse builder IEC-D+Silk Gel. Therefore, adding silk gel to detergent IEC-D results in reduced stain formation on glassware and improved visibility (see Figure 1). In the above experiment, spider-derived silk polypeptide C 16 The use of is preferred.
