Description

240645W0011Ketal or acetal diamines and their useOptimization of grease cleaning is an ongoing task in the cleaning field, in particular for hand dishwash formulations.Consumers utilizing liquid dishwashing detergent compositions tend to wash greasy, difficult to clean items at the end of their washing procedure, after easier to clean items such as glasses and flatware are cleaned. Such liquid dishwashing detergent compositions require a high suds profile while providing grease cleaning.Surfactant is needed to ensure grease cleaning and sudsing under neat and diluted usage. However, surfactant can leave visible films and cause streaks and spots on the rinsed dishware surfaces. Therefore, there is a need to find other classes of chemical compounds to support surfactants in grease cleaning.A further strongly emerging trend in cleaning industry is the desire to improve the "footprint” of any product, be it in terms of its origin like being from natural or renewable resources, or compared to previous products, its production in terms of production efficiency and thus reduced usage of energy, its efficiency in usage such as reduced amounts for the same performance or higher performance at the same amount levels used, its persistence in the natural environment after its usage, especially its biodegradation, since recycling is technically very challenging and therewith economically not attractive.Hence, due to the climate change, one of the most important targets of the detergent and cleaner (D&C) industry today is to significantly lower the CO2 emission per wash I cleaning process, by improving cold water conditions, improving the cleaning efficiency at low temperatures of 30 °C and below, and to lower the amounts of chemicals employed per wash, and increasing the weight-efficiency of the cleaning technologies. Another important target of the D&C industry is the need for biodegradable components, to improve the sustainability of the cleaning formulations and to avoid the potential accumulation of the cleaning components or their degradation products, resulting from incomplete biodegradation of the components in the ecosystem, thus lowering the persistence in nature after usage of the materials.Alternative chemical compounds which provide on the one hand a significant wash performance, in particular in grease cleaning, and on the other hand demonstrate a high rate of biodegradability are of interest to the D&C industry to overcome the above-mentioned challenges.One such alternative group of compounds, as shown in the present invention, are ketal or acetal diamines (KDA).In the following, a summary of the most relevant publications in the field of the present invention, namely ketal or acetal diamines and their uses, is given.The non-disclosed patent application WC2024175409 A1 describes compounds that comprise a ketal or acetal group and two amino groups that are reacted with ethylene imine and are subsequently alkoxylated. The use of these compounds is described for washing and cleaning purposes. However, in contrast to this patent application240645W0012 the present ketal or acetal diamines are not part of a higher polymeric structure (such as a polyethylene imine) and are not modified by alkoxy lation.The company Aditya Birla Chemicals, Mumbai, India commercially distributes a product portfolio of Recyclamines® directed to compounds comprising a ketal or acetal group and at least two amino groups. These compounds are marketed as curing agents or hardeners for epoxy resins to introduce acid cleavable groups which allow recycling of the otherwise thermoset resin. In line with this different (non-cleaning) application requirements, the compounds of the Recyclamine® series have not been disclosed in combination with typical cleaning components, such as enzymes, builders and surfactants.US2019 / 0016667 A1 discloses diaminoacetals and diaminoketals and their synthesis. However, these compounds are solely described as being useful in the infusion of large composite structures, such as the creation of fiberglass composite windmill blades. No wash and cleaning applications are mentioned.WO2021 / 154569 A1 discloses cleaning compositions for removing grease and / or body soils from a surface comprising a linear alkyl benzene sulphonate surfactant, an alkyl ethoxylated sulphate surfactant and an alkoxylated polymer comprising a core structure selected from a linear oligoamine, a sugar alcohol and a cyclic amine. Herein, the amines are part of an alkoxylated polymer. The use of the unmodified amine as additive to such cleaning compositions is not described, while also not ketal- and / or acetal-containing amine structures are disclosed.US10611985, EP 3118291 A1 and EP 2940115 A1 disclose liquid detergent compositions which comprise a cyclic amine, in particular methylcyclohexyl diamine ("MCDA”, brand name: Baxxodur® EC210 marketed by BASF SE). The diamine MCDA delivers a robust grease cleaning performance of the cleaning composition across different water hardnesses, it is however non-biodegradable (Source: ECHA website echa.europa.eu: -1% biodegradation in OECD 301 C under GLP conditions after 28 days exposure, and 12% in OECD 301 B under GLP conditions after an exposure of 56 days). No ketal- and / or acetal-containing amine structures are disclosed.Thus, the present inventors surprisingly found that combining ketal or acetal diamines (KDA) with well-known cleaning components, will result in superior wash properties while at the same time the KDAs provide a significant degree of biodegradability. These surprising data open up the opportunity for the preparation of new eco-friendly cleaning formulations that possess significant grease cleaning capacities.Therefore, the object of the present invention is to provide a novel cleaning composition comprising(i) at least one first compound comprising at least two primary and / or secondary amino groups and at least one ketal or acetal group;(ii) at least one second compound selected from the group consisting of surfactant, enzyme and builder; and(iii) water.In another aspect, the invention is directed to a cleaning method and uses of the inventive composition in cleaning formulations and compositions.240645W0013Thus, subjects of the present invention are the following Embodiments 1 to 13 as defined and further explained with further embodiments hereinafter and further exemplified in the experimental section:Embodiment 1A cleaning composition comprising(I) at least one first compound comprising at least two primary and / or secondary amino groups and at least one ketal or acetal group;(ii) at least one second compound selected from the group consisting of surfactant, enzyme and builder; and(ill) water.The first compound comprising at least two primary and / or secondary amino groups and at least one ketal or acetal group can be synthesized as described in US2019 / 0016667 A1 reacting an alkanolamine with e.g. ethyl vinyl ether (to generate an acetaldiamine) or methoxy propene (to generate ketaldiamines). Both reactants are well-known compounds and are commercially available in large volumes. A typical example of such a well-known alkanolamine is ethanol amine. Ethanolamine can also be produced by fermentation in microbial strains as described, for example, in US20090325245 A1 .Thus, the ketal or acetal diamines of the invention may be prepared from alkanolamines that are renewable compounds, preferably directly isolated from an organism such as bacteria, algae, fungi, plants or even higher organisms.In preferred embodiments the amount of non-fossil carbon atoms in the ketal or acetal diamine of the inventive composition is at least 10%, at least 20%, at least 40%, at least 70%, at least 95% or they solely comprise nonfossil derived carbon atoms compared to the total amount of carbon atoms in the ketal or acetal diamine.In even more preferred embodiments, the whole inventive cleaning composition (including the KDA and the second and third components and optionally further components) possesses an amount of non-fossil carbon atoms that is at least 10%, at least 20%, at least 40%, at least 70%, at least 95% or it solely comprises non-fossil derived carbon atoms compared to the total amount of carbon atoms in the inventive cleaning composition.In preferred embodiments, the first component (KDA) or the whole cleaning composition of the present invention demonstrate a biodegradation of at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70% or at least 80% biodegradability according to the OECD standard 301 B, C, D or F within 28 days. The OECD standards 301 B, C, D and F are all respirometry test methods. The skilled person is well-aware of these tests and therefore solely OECD standard 301 F will be described representatively.For the purposes of this invention, aerobic biodegradation in wastewater according to OECD 301 F is expressed as a percentage of the theoretical oxygen demand (ThOD, which is measured by the elemental analysis of the compound of interest), which is needed to completely biodegrade the compound sample. Thus, the amount of240645W0014 oxygen taken up by the microbial population during biodegradation of the test substance (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD. The obtained values are preferably measured in triplicate using the OECD 301 F manometric respirometry method. The consumption of oxygen is determined by measuring the change in pressure in the apparatus using an OxiTop® C (Xylem 35 Analytics Germany Sales GmbH & Co KG). Details for the tests performed are given in the experimental section below.The OECD standards OECD 301 A, E and 302 B are Dissolved Organic Carbon (DOC) tests. Also, these tests are well-known for the skilled person. Therefore, solely OECD standard 301 A will be described representatively.Standard OECD 301 A is a DOC Die Away Test: The test substance is used at a high concentration compared to the other tests, i.e. 10-40 mgDOC / L (DOC = Dissolved Organic Carbon). The DOC concentration is measured at defined intervals over a period of 28 days.However, the skilled person is also aware of other tests that can or may be used to determine or indicate the biodegradability of the KDA or inventive composition. These tests in principle include chemical, physical and biological tests. For example, the used test may be based on the specific activity of an indicator enzyme or the amount of expression of an indicator gene. In such tests, the KDA or inventive composition demonstrate a significant biodegradability, i.e. at least 20%, at least 30%, at least 40%, at least 50%, at least 60% or at least 70% of the maximum biodegradation.In preferred embodiments, the KDA or the composition of the present invention demonstrate a biodegradation of at least 20%, at least 30%, at least 40%, at least 50%, at least 60% or at least 70% biodegradability according to the OECD standard 301 A, E or 302 B within 28 days.In preferred embodiments, the ketal or acetal diamine (KDA) of the inventive cleaning composition has a molecular weight (M) (also called molecular mass) of less than 1000 g / mol, preferably of less than 500 g / mol, more preferably of less than 300 g / mol.

Proteases include aminopeptidases (EC 3.4.11), dipeptidases (EC 3.4.13), dipeptidyl-peptidases and tripeptidyl-peptidases (EC 3.4.14), peptidyl-dipeptidases (EC 3.4.15), serine-type carboxypeptidases (EC 3.4.16), metallocarboxypeptidases (EC 3.4.17), cysteine-type carboxypeptidases (EC 3.4.18), omega peptidases (EC 3.4.19), serine endopeptidases (EC 3.4.21), cysteine endopeptidases (EC 3.4.22), aspartic endopeptidases (EC 3.4.23), metallo-endopeptidases (EC 3.4.24), threonine endopeptidases (EC 3.4.25), or endopeptidases of unknown catalytic mechanism (EC 3.4.99).At least one protease may be selected from metallo-endoproteases (EC 3.4.24). A metalloprotease may for example be a thermolysin from, e.g., family M4 or another metalloprotease such as those from M5, M7 or M8 families. A metalloprotease may especially be derived from Bacillus amyloliquefaciens described in WO 07 / 044993A2, from Bacillus, Brevibacillus, Thermoactinomyces, Geobacillus, Paenibacillus, Lysinibacillus or Streptomyces spp. described in WO 2014194032, WO 2014194054, and WO 2014194117, from Kribella alluminosa described in WO 2015193488, and from Streptomyces and Lysobacter described in WO 2016075078.More preferably, at least one protease may be selected from serine proteases (EC 3.4.21). Serine proteases or serine peptidases are characterized by having a serine in the catalytically active site, which forms a covalent adduct with the substrate during the catalytic reaction. A serine protease may be selected from the group consisting of chymotrypsin (e.g., EC 3.4.21.1), elastase (e.g., EC 3.4.21.36, EC 3.4.21.37, or EC 3.4.21.71), granzyme (e.g., EC 3.4.21 .78 or EC 3.4.21 .79), kallikrein (e.g., EC 3.4.21 .34, EC 3.4.21 .35, EC 3.4.21.118, or EC 3.4.21.119,) plasmin (e.g., EC 3.4.21.7), trypsin (e.g., EC 3.4.21.4), thrombin (e.g., EC 3.4.21.5), and subtilisin. Subtilisin is also known as subtilopeptidase, e.g., EC 3.4.21.62, the latter hereinafter also being referred to as "subtilisin”.Subtilisins and chymotrypsin-related serine proteases both have a catalytic triad comprising aspartate, histidine and serine. In the subtilisin related proteases the relative order of these amino acids, reading from the amino to carboxy-terminus, is aspartate-histidine-serine. In contrast, in the chymotrypsin-related proteases the relative order is histidine-aspartate-serine. Thus, subtilisin herein refers to a serine protease having the catalytic triad of subtilisin related proteases. Examples include the subtilisins as described in WO 89 / 06276 and EP 0283075, WO 89 / 06279, WO 89 / 09830, WO 89 / 09819, WO 91 / 06637 and WO 91 / 02792.Parent proteases of the subtilisin type (EC 3.4.21.62) and variants may be bacterial proteases.

The grease-covered sticks are stored at 4 °C for at least 24 hours.To measure the grease cleaning performance of individual cleaning compositions, the grease-covered sticks are placed over slightly moving / swirling microplates, each containing 4 wt% wash solutions of the to-be-tested cleaning compositions. The grease-covered sticks are dipped into the test solutions without coming into contact with the walls or bottom of the microplate and are kept in the swirling test solutions during the wash time. The wash temperature is 25° C.The removal of grease is quantified via a measurement of the fluorescence of the test solutions. From the measured fluorescence, the Cleaning Index is calculated, using the following equation:(fluorescence of the test solution with additive / fluorescence of the reference solution)*100.Table 1 shows the cleaning compositions (Comp) which were tested, while Table 2 shows the measured fluorescence and calculated Cleaning Indices. The higher the Cleaning Index, the better the grease cleaning performance of the composition. The values shown in Table 2 are averaged over 4 tests.240645W00123Table 1CE = comparative example; IE = inventive exampleAdditive 1:This ketaldiamine is prepared using the HCI-salt of ethanolamine and methoxy propene as described in patent WO2019 / 240841 (Connora Technologies).Additive 2:240645W00124This hydrophobized ketaldiamine is prepared using the HCI-salt of 2-amino-2-methyl-propanol and methoxy propene as described in patent WO2019 / 240841 (Connora Technologies).Table 2From T able 2, one can see the significant cleaning benefit of both ketaldiamine additives (Comp C and D) compared to the non-additive containing, C12-C14 dimethyl amine oxide based formulations (Comp A and B). In addition, Additive 1 also shows a significant benefit compared to the non-additive containing, cocamidopropyl betaine enriched formulations (Comp G versus Comp E and Comp F).The biodegradability performance of both additives is shown in Table 3. While Additive 1 shows a biodegradation of 57% after 28 days and 90% after 56 days in OECD 301 F, the hydrophobized ketaldiamine (Additive 2) shows a lower biodegradation at 28 d and 56 d, due to an extended sludge adaptation phase (about 10 d). It is plausible that also Additive 2 will reach 80-90% biodegradation if the total measurement time will be extended to about 84 days, since the biodegradability curve at 56 days is still increasing steeply.Table 3
