Definitions

  • Biodegradable amine containing alkoxy lates their preparation, uses, and compositions comprising them
  • This invention deals with biodegradable amine containing alkoxylates (in this present invention abbreviated as "inventive compound”, or “inventive polymer”, “alkoxylated polymer” or “compound of the invention” whenever the inventive amine containing alkoxylates are meant), their manufacture, their uses, particularly for use in cleaning compositions such as laundry detergent compositions, and specifically for improved clay removal and/or oily/fatty soil removal and/or body soil removal and/or whiteness maintenance in laundry care.
  • cleaning compositions such as laundry detergent compositions, and specifically for improved clay removal and/or oily/fatty soil removal and/or body soil removal and/or whiteness maintenance in laundry care.
  • Detergent formulators are continuously faced with the task of developing improved products to remove a broad spectrum of soils and stains from fabrics and hard surfaces.
  • Chemically and physico-chemically the varieties of soils and stains spectrum range from polar soils, such as proteinaceous, clay, and inorganic soils, to non-polar soils, such as soot, carbon-black, by-products of incomplete hydrocarbon combustion, and organic soils like sebum and body soils.
  • polar soils such as proteinaceous, clay, and inorganic soils
  • non-polar soils such as soot, carbon-black, by-products of incomplete hydrocarbon combustion, and organic soils like sebum and body soils.
  • the removal of greasy (i.e., oily/fatty) stains has been a particularly challenging problem. This challenge has been accentuated by the recent high interest and motivation to reduce the level of surfactants in cleaning detergents for environmental, sustainability and cost reasons.
  • anionic surfactants such as linear alkyl benzene sulfonate, LAS
  • a further strongly emerging trend 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.
  • D&C detergent and cleaner
  • Another important target of the D&C industry is the need for biodegradable polymers, to improve the sustainability of the detergent formulations and to avoid the potential accumulation of the polymers or their degradation products, resulting from incomplete biodegradation of the polymers in the ecosystem, thus lowering the persistence in nature after usage of the materials.
  • biodegradable cleaning polymers that provide both excellent primary (i.e., soil removal) and/or secondary (i.e., whiteness maintenance) cleaning benefits for both hydrophobic and hydrophilic stains, and an improved biodegradability.
  • the materials should exhibit good soil removal for oily/fatty/sebum and particulate stains and/or should also lead to improved whiteness maintenance, minimizing the amount of suspended and emulsified oily/fatty/sebum and particulate soil from redepositing on the surfaces of the textiles or hard surfaces.
  • the new ingredients would also display a synergy with other cleaning technologies, such as other cleaning polymers, surfactants and/or enzymes, known for improving solely the oily/fatty/sebum or particulate stain removal and/or whiteness of fabrics and hard surfaces, leading to further improved detergent compositions.

The document is silent about the biodegradability of the disclosed compounds and solely shows wash performance.
  • the present invention is directed to polymers combining linear amines with free NH-groups and nitrogen comprising multi acids. This combination results in structurally different polymers than the ones of WO2021254824 A possessing a higher nitrogen density with increased wash performance and significant biodegradability.
  • amine containing alkoxylates synthesized according to the present invention demonstrate in parallel excellent wash performance and show a significant biodegradation.

Further, the inventive compounds also show good stability in cleaning composition, especially in liquid cleaning composition.
  • the object of the present invention is to provide novel alkoxylated polymers obtainable by a process comprising the following steps:
  • first alkylene oxide (AO1) preferably selected from the group consisting of at least one of a first ethylene oxide (EO1), first propylene oxide (PO1), and first butylene oxide (BO1), in order to obtain the alkoxylated polymer.

Description

Biodegradable amine containing alkoxy lates, their preparation, uses, and compositions comprising them
This invention deals with biodegradable amine containing alkoxylates (in this present invention abbreviated as "inventive compound”, or "inventive polymer”, "alkoxylated polymer” or "compound of the invention” whenever the inventive amine containing alkoxylates are meant), their manufacture, their uses, particularly for use in cleaning compositions such as laundry detergent compositions, and specifically for improved clay removal and/or oily/fatty soil removal and/or body soil removal and/or whiteness maintenance in laundry care.
Detergent formulators are continuously faced with the task of developing improved products to remove a broad spectrum of soils and stains from fabrics and hard surfaces. Chemically and physico-chemically, the varieties of soils and stains spectrum range from polar soils, such as proteinaceous, clay, and inorganic soils, to non-polar soils, such as soot, carbon-black, by-products of incomplete hydrocarbon combustion, and organic soils like sebum and body soils. The removal of greasy (i.e., oily/fatty) stains has been a particularly challenging problem. This challenge has been accentuated by the recent high interest and motivation to reduce the level of surfactants in cleaning detergents for environmental, sustainability and cost reasons. A reduction of the amount of surfactants added, especially a reduction of anionic surfactants, such as linear alkyl benzene sulfonate, LAS, has typically been found to lead to an erosion of oily/fatty stain removal. Additionally, the global trend of using washing conditions at lower temperature further diminishes grease cleaning capabilities of typical detergents, since the class of oily and fatty stains shows the greatest performance drop when the temperature is decreased. On the other hand, clay soil stains, although in some instances contacting the fabric fibers with less force, nevertheless provide a specific type of soil removal problem due to the high degree of charge associated with the clay itself. This high surface charge density may act to repel some laundry ingredients, thus surfactants alone cannot remove or carry away the clay into the laundry liquor.
Another global trend is the compaction of laundry detergents, in order to improve the sustainability in terms of water usage and/or transportation costs, as well as to improve the convenience for the end consumer (e.g., single mono dose products, tabs, pouches and the like), which leads to a high market demand for new raw materials that have a higher weight-efficiency and a significantly broader performance profile.
A further strongly emerging trend 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, 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 polymers, to improve the sustainability of the detergent formulations and to avoid the potential accumulation of the polymers or their degradation products, resulting from incomplete biodegradation of the polymers in the ecosystem, thus lowering the persistence in nature after usage of the materials.
As a result of these trends, there is a strong need for new biodegradable cleaning polymers that provide both excellent primary (i.e., soil removal) and/or secondary (i.e., whiteness maintenance) cleaning benefits for both hydrophobic and hydrophilic stains, and an improved biodegradability. The materials should exhibit good soil removal for oily/fatty/sebum and particulate stains and/or should also lead to improved whiteness maintenance, minimizing the amount of suspended and emulsified oily/fatty/sebum and particulate soil from redepositing on the surfaces of the textiles or hard surfaces. Preferably, the new ingredients would also display a synergy with other cleaning technologies, such as other cleaning polymers, surfactants and/or enzymes, known for improving solely the oily/fatty/sebum or particulate stain removal and/or whiteness of fabrics and hard surfaces, leading to further improved detergent compositions.
For example, alkoxylated polyalkylene imine and alkoxylated polyamine polymers, especially the class of alkoxylated hyperbranched polyethylene imine (PEI) and alkoxylated linear polypropylene imine (PPI) homo- and copolymers, are known in the literature to be able to contribute to particulate or to oily/fatty soil removal, especially at low surfactant levels and at cold water conditions (30 °C and below). However, their biodegradation performance generally is poor, and thus not acceptable for current and future requirements. Ideally, the polymers are readily biodegradable, i.e., show equal to or more than 60% oxygen consumption after 28 days in the OECD 301 F test or they are considered moderately biodegradable then they show equal to or more than 40% after 28 days in the OECD 301 F test. Alternatively, the polymers are inherently biodegradable in the OECD 302 B test, i.e., show equal to or more than 70% dissolved organic carbon (DOC) levels. Hence, there is a need to find improved polymer architectures with a similar or superior performance profile, a feasible preparation process and an improved biodegradation behavior.
In the following, a summary of the most relevant publications in the field of the present invention, amine containing alkoxylates, is given.
WO2021254824 A discloses amine containing alkoxylates obtained by reacting diamines with cycloalkylene groups and polycarboxylic compounds having three to ten carboxyl groups and subsequent alkoxylation. The document is silent about the biodegradability of the disclosed compounds and solely shows wash performance. In contrast to WO2021254824 A the present invention is directed to polymers combining linear amines with free NH-groups and nitrogen comprising multi acids. This combination results in structurally different polymers than the ones of WO2021254824 A possessing a higher nitrogen density with increased wash performance and significant biodegradability.
Surprisingly, the present inventors found that amine containing alkoxylates synthesized according to the present invention demonstrate in parallel excellent wash performance and show a significant biodegradation. Experimentally generated data proved that the inventive compounds can be used in combination with established components to significantly improve wash performance. Further, the inventive compounds demonstrate significant biodegradation (at least around 40% according to OECD 301 F within 28 days), whereas such biodegradation rate can be observed for polymers having a molecular weight average weight (Mw) of up to 46.000 g/mol. Further, the inventive compounds also show good stability in cleaning composition, especially in liquid cleaning composition.
Therefore, the object of the present invention is to provide novel alkoxylated polymers obtainable by a process comprising the following steps:
(i) reaction of
(a) at least one first amine (A1) or pre-alkoxylated amine (pA);
(b) at least one aliphatic carboxylic acid or salts, esters or anhydrides thereof (B);
(c) at least one amino group containing polycarboxylic acid or salts, amino group containing esters or amino group containing anhydrides thereof (C); and
(d) optionally at least one alkanolamine (D), in order to obtain a first intermediate (11), and
(ii) reaction of
(a) the first intermediate (11) with
(b) first alkylene oxide (AO1), preferably selected from the group consisting of at least one of a first ethylene oxide (EO1), first propylene oxide (PO1), and first butylene oxide (BO1), in order to obtain the alkoxylated polymer.
In the following, any alkylene oxide is generically referred to as "AO”, ethylene oxide is sometimes referred to as "EO” and propylene oxide as “PO”. "PEO” is used sometimes herein to describe polyethylene oxide homopolymers or PEO-blocks within a larger polymer structure; likewise, "PPO” describes the polypropylene oxide homopolymers or polymer-blocks within a larger polymer structure.
A process to produce the inventive compounds is also part of this invention. The use of the compounds of this invention for all kinds of applications for which the previously described polyamines, polyethylene imines, polypropylene imines, and their alkoxylated derivates have been used is encompassed by this present invention as well.
Compositions comprising such amine containing alkoxylates of this invention similar to those compositions in which the previously known polyamines, polyethylene imines, polypropylene imines, and their alkoxylated derivates have been employed - either the inventive amine containing alkoxylates instead of such known compounds or in combinations with such known compounds - forms part of this invention as well.
The term "compound of the invention”, or "inventive compound”, or "inventive polymer”, as used herein, refers to amine containing alkoxylates prepared as described below and/or in the appended claims.
Thus, subjects of the present invention are the following Embodiments 1 to 28 as defined and further explained with further embodiments hereinafter and further exemplified in the experimental section:
Embodiment 1
An alkoxylated polymer obtainable by a process comprising the following steps:
(I) reaction of
(a) at least one first amine (A1) or pre-alkoxylated amine (pA);
(b) at least one aliphatic carboxylic acid or salts, esters or anhydrides thereof (B);
(c) at least one amino group containing polycarboxylic acid or salts, amino group containing esters or amino group containing anhydrides thereof (C); and
(d) optionally at least one alkanolamine (D), in order to obtain a first intermediate (11), and
(ii) reaction of
(a) the first intermediate (11) with
(b) first alkylene oxide (AO1), preferably selected from the group consisting of at least one of a first ethylene oxide (EO1), first propylene oxide (PO1), and first butylene oxide (BO1), in order to obtain the alkoxylated polymer.
The compounds of the invention comprise side chains, alkylene oxide branches, which are attached to oxygen or nitrogen atoms derived from the -OH, -COOH and NH-functionalities of the first intermediate (11). The side chains are made up from alkylene oxides, preferably ethylene oxides and propylene oxides. Typically, a side chain possesses on average 25 to 75 total AO units (EO units + PO units). More detailed embodiments describing the different chain lengths are provided below. The side chains comprise, and preferably consist of ethylene oxides and propylene oxides. The side chains preferably end with an -OH group but may alternatively be capped, such as with a C1 to 020 alkyl group, preferably 01 to 06 alkyl group, more preferably 01 alkyl group.
It is noted that all such numbers are numbers "on average” meaning that such numbers refer to the average number for such unit for one -OH, -C00H or NH-functionality calculated based on all -OH, -C00H and NH-functionalities of the first intermediate (11).
It is to be emphasized that the reactions leading to the inventive compounds are statistical reactions, meaning there is never just one chemically exactly defined compound present, but an inventive amine containing alkoxylate always is a mixture of slightly deviating structures, all stemming from the same reaction within one reaction space; the difference of those structures clearly stemming from the facts that no reaction proceeds in exactly the same way and the same speed on all functional units, especially as the chemical reactivities of the functional units - here those of the -OH, -C00H and NH-functionalities, differs according to their environment, meaning that, for example, a primary alcohol group reacts differently than a secondary alcohol, and also the chemical environment of the groups may be different; this leads in an overall view to slightly deviating structures being present, and thus any compound of this invention being defined as in the various embodiments including the numbered Embodiments 1 to 28, and exemplified in the examples never is just one chemical compound, but always a mixture of slightly deviating compounds, having a statistical distribution. As the reactivities of those groups are not differing by a large extent, the deviation is relatively small. Hence, defining an amine containing alkoxylate of the invention by a prototypical member is a viable way of defining the structure. Also, defining the composition of the side chains by average numbers (including those variables defined in the present and following Embodiments based on the numbers of -OH, -C00H or NH-functionalities being present in the first intermediate (11) is a useful way of defining the overall composition of any mixture herein defined as "an amine containing alkoxylate of the invention”.
Therefore, unless otherwise indicated, the values, ranges and ratios given in the specification for the number of functional groups and the molecular weight (Mn) relate to the number average values in heterogenic mixture of the synthesized amine containing alkoxylate containing individual, slightly from each other deviating chemical structures that result from the preparation method of the present invention. As known in polymer science, the weight-average molecular weight (Mw) is then a measure for the (in)homogeneity within the mixture of different species in "the amine containing alkoxylate”.
In line with the above, it is preferred that all functional groups, namely -OH, -C00H or NH-functionalities, of the first intermediate (11) have been substituted with alkylene oxide branches and the alkylene oxide branches have slight variations in the amounts of the different alkoxy lations. Inventive compounds bearing the above-described modification are also called being “alkoxylated”, "ethoxylated and propoxylated” and/or "modified”.
The term "alkylene oxide branch”, as used herein, refers to a sub-structure of the inventive compounds comprising, essentially consisting of or consisting of a plurality of AO units, preferably EO units and PO units.
The terms "essentially having” or "having essentially”, as used interchangeably herein, with respect to the inventive compounds mean that said polymers may comprise impurities or other types of polymers in an amount not more than 40% w/w, not more than 30% w/w, not more than 20% w/w, not more than 10% w/w, not more than 7% w/w, not more than 5% w/w, not more than 3% w/w, not more than 2% w/w, not more than 1% w/w, not more than 0.5% w/w or not more than 0.1 % w/w.
In preferred embodiments, the weight average molecular weight (Mw) of the amine containing alkoxylates is in the range of from 4.000 to 60.000 g/mol, preferably in the range of from 8.000 to 55.000 g/mol, more preferably in the range of from 15000 g/mol-50.000 g/mol.
The person skilled in the art knows how to determine/measure the respective weight average molecular weight (Mw). This can be done, for example, by using size exclusion chromatography (such as GPC, e.g., in combination with light scattering), by mass spectrometry, by mass photometry or by calculation from the used molar ratio of starting materials. Preferably, Mw values are determined by the method as follows: OECD TG 118 (1996), which means in detail
OECD (1996), Test No. 118: Determination of the Number-Average Molecular Weight and the Molecular Weight Distribution of Polymers using Gel Permeation Chromatography, OECD Guidelines for the Testing of Chemicals, Section 1, OECD Publishing, Paris, also available on the internet, for example, under https://doi . orq/10.1787/9789264069848-en .
Molecular weights of the amine containing alkoxylates and intermediates may be determined by gel permeation chromatography (GPC).
In preferred embodiments, the weight average molecular weight (Mw) of the inventive polymers or intermediates is measured as follows: GPC measurements were performed in HFIP (hexafluoro-isopropanol) at ambient temperature by PSS Agilent 1260 Series. The nominal solvent flow rate was 1 mL/min. Two SEC columns with a pore size of 100 and 1000 for HFIP from PSS Polymer Standards were used for fractionation. The refractive index detector G1362A and UVA/is detector G1365D from Agilent Technologies were used for HFIP. The calibration was carried out with poly(methylmethacrylate). The results were evaluated using WinGPC UniChrom V 8.20 software from Polymer Standards Service GmbH resulting in different parameters including the weight average molecular weight (Mw).
"Mw” is the weight average molecular weight and "Mn” is number average molecular weight.
In preferred embodiments, the number average molecular weight (Mn) of the inventive polymers and intermediates is measured as described for the weight average molecular weight (Mw) with the exception that the WinGPC UniChrom V 8.20 software determines the number average molecular weight (Mn).
In preferred embodiments, the acid numbers of the inventive polymers and intermediates can be determined according to DIN EN ISO 2114.
In preferred embodiments, the hydroxyl numbers (OH numbers) of the inventive polymers and intermediates can be determined according to DIN EN ISO 4629-1.
In preferred embodiments, the amine numbers of the inventive polymers and intermediates can be determined according to DIN EN ISO 9702.

In preferred embodiments of the above processes, 25 mol to 35 mol, preferably 27 mol to 32 mol of the first ethylene oxide (EO1) is employed per mol of the sum of NH-functionality, -OH group and -COOH group of the first intermediate (11) and (independently or in combination) 5 mol to 20 mol, preferably 7 mol to 15 mol of the first propylene oxide (PO1) is employed per mol of the sum of NH-functionality, -OH group and -COOH group of the first intermediate (11).

Alternatively, the alkylene oxide branches possess a block structure consisting of an EC block and a PC block, wherein the PC block is reacted with the first intermediate (11).
Within the context of the present invention, the term "NH-functionality” is defined as follows: a primary amino group (-NH2) has two NH-functionalities, a secondary amino group only one NH-functionality, and a tertiary amino group, by consequence, has no reactive NH-functionality. The skilled person will understand that the first intermediate (11) may also be alkoxylated with other AOs than ethylene oxide or propylene oxide. In this context, butylene oxide is mentioned. Further, the skilled person is also well-aware of helpful modifications of the alkoxy chain, such as modifications with lactones or hydroxy carbon acid as described in WO2021165468 A.
It is noted that the alkylene oxide used to prepare the inventive compounds may be derived from a fossil or nonfossil carbon source or even a mixture of the before mentioned. Preferably, the amount of non-fossil carbon atoms in the alkylene oxide branch 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. The skilled person is well-aware of commercial alkylene oxide products made of non-fossil carbon sources (these products are often sold as being sustainable, renewable or bio-based). For example, Croda International, Snaith, UK, sells ethylene oxide and related products based on bio-ethanol as ECO Range. Additionally, methods to prepare bio-based propylene oxide are also known (see Abraham, D. S., "Production of propylene oxide from propylene glycol" Master's Thesis University of Missouri-Columbia (2007) (75 pages)).
Alternatively, the alkylene oxide may comprise non-fossil carbon atoms due to a synthesis involving recycling processes. For example, waste plastics can be recycled in a process resulting in ethylene (see Royer, SJ et al., PLoS One. 2018; 13(8): e0200574 and Kim, SW et al., Science of The Total Environment, Volume 903, 10 December 2023, 166789). In a subsequent synthesis step the recycled and non-fossil ethylene can be converted into ethylene oxide (EC). Such conversion steps are well-known to the person skilled in the art (e.g. WO2021092313 A).
In further preferred embodiments, the skilled person will also partially or fully replace fossil educts, such as the first amine (A1), the second amine (A2), the aliphatic carboxylic acid or salts, esters or anhydrides thereof (B), the amino group containing polycarboxylic acid or salts, amino group containing esters or amino group containing anhydrides thereof (C) and the alkanolamine (D) with non-fossil forms of such educts. In preferred embodiments, at least one of the above-described educts comprises at least 10%, at least 20%, at least 40%, at least 70%, at least 95% of non-fossil derived carbon atoms. For example, the amino group containing polycarboxylic acid may be ethylenediaminedisuccinic acid (EDDS) and the skilled person is well-aware of fermentative processes to obtain EDDS, such as disclosed by Edenhart et al. (Edenhart et al., Metabolic Engineering, Volume 60, July 2020, Pages 148-156).
Embodiment 9 In preferred embodiments, the amine containing alkoxylates of the invention demonstrates at least 20%, at least 30%, at least 40%, preferably at least 50% or more preferably at least 60% biodegradability according to standard OECD 301 F within 56 days, preferably within 28 days.
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 of 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).

The amine containing alkoxylates according to any of Embodiments 1 to 9, wherein all alkylene oxide branches attached to the first intermediate (11) have the same structure, in that sense that the number of EO and/or PC units per alkylene oxide branch is identical or, alternatively, the alkylene oxide branch structures vary slightly.
Without wishing being bound by the following explanation, a rationale exists to explain the resulting structures of the amine containing alkoxylates: Due to the fact that the reactions in questions necessarily employed to prepare those structural orders of the side chains, and thus to prepare the specific inventive compounds, are reactions of quite reactive species which can lead under suitable conditions to almost complete and even "essentially complete” conversions of almost 100 % if not even 100%, the statistical deviation of the composition of the mixture of "amine containing alkoxylates” in question is not that high, which in turn means that the structural order of the side chains do not show much deviation. Thus, it is a reliable assumption which can in principle be proven by sophisticated and thus time-consuming and expensive analytical means - such as multi-dimensional NMR-analyses - that it is generally accepted that such deviation exists; hence, no "specific amine containing alkoxylates” will be "just one chemical compound of a clearly defined chemical structure”, but clearly will consist of a) a mixture of slightly differing compounds, such differences lying in b) slight deviations may already in the structure of "the (unmodified) first intermediate (11)” being employed for the further modification steps, and c) the slight deviations in the structural orders of the side chains may be attached by way of d) multi-step reactions due to e) variations in the chemical reactivities of the -NH, -COOH and -OH groups, and f) due to slight inhomogeneities occurring in a commercial scale process. All of those factors a) to f) - to just mention a few important ones - lead to a "specific amine containing alkoxylate” which is not one specific chemical compound but in fact a mixture of slightly differing compounds having an overall very similar chemical structure; thus, such structure is best described by average numbers for the variables and percentages for the amounts of the dominating structural order.
Embodiment 11
In another embodiment of the present invention, it is preferred that up to 100% of the nitrogen atoms present in the amine containing alkoxylates are quaternized, preferably the degree of quaternization of the nitrogen atoms present in the amine containing alkoxylates lies in the range of 10% to 95%, 20% to 90% or 50% to 85%.
Moreover, the polymers of the invention may be further sulfated. The skilled person is well-aware how the inventive polymers can be quaternized and/or sulfated.

The conversion rate of the two reaction steps may be monitored and in preferred embodiments the conversion rate for the first or second step is at least 95%, preferably at least 99%, and even more preferably at least 99,5 % or even more. All other structural orders of the side chains as defined above but also the undefined structures resulting from non-controllable parameters are performed in this defined manner, leading - on statistical average - to a defined structural order directly derived from the way such reaction is performed.
The conversion rate of the reaction can be determined according to methods known to the skilled person, such as NMR-spectroscopy, such as 13C-NMR-spectroscopy and/or 1 H NMR-spectroscopy.

In case that after the reaction leading to the inventive compound residual educts (amines, carboxylic acids, amino group containing carboxylic acids, alkanolamines and/or alkylene oxide) are present to a non-desirable extent, the resulting product mixture containing the amine containing alkoxylates may be further purified by standard means to reduce the content of residual educts, but also to reduce the amount of possible by-products, reduce the amount(s) of the solvent(s) employed (i.e., to concentrate) or replace solvent(s) with other solvents. Such processes are known to a person of skill in this field.
Preferably, undesirable amounts of residual non-reacted educts are removed, preferably by means of distillative processes, more preferably by thermal distillative processes, which may additionally comprise the application of reduced pressure to increase the speed and/or the effectiveness of the removal.

Polymer biodegradability
Biodegradation in wastewater was tested in triplicate using the OECD 301 F manometric respirometry method. OECD 301 F is an aerobic test that measures biodegradation of a sample by measuring the consumption of oxygen. To a measured volume of medium, 100 mg/L test substance, which is the nominal sole source of carbon is added along with the inoculum (30 mg/L, aerated sludge taken from Mannheim wastewater treatment plant). This is stirred in a closed flask at a constant temperature (20°C or 25°C) for 28 or 56 days, respectively. 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). Evolved carbon dioxide is absorbed in a solution of sodium hydroxide. Nitrification inhibitors are added to the flask to prevent usage of oxygen due to nitrification. The amount of 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 (Theoretical oxygen demand, which is measured by the elemental analysis of the compound). A positive control Glucose/Glucosamine is run along with the test samples for each cabinet.

Table 1 shows the base liquid laundry detergent without any polymer (LLD.1) that has been used to carry out the application tests to determine the impact of the inventive polymers on the primary cleaning performance.
Table 1. Composition of the base liquid laundry detergent.
*) All data are wt% active ingredient, independent of the respective product form. Primary cleaning performance
To determine the primary detergency, the cleaning performance on 4 different particulate stains on a polyester fabric (CFT, Vlaardingen, The Netherlands) was measured by determining the color difference (delta E) between the stains before and after wash using a reflectometer (Mach5 plus, a multi area color measurement instrument from ColourConsult). Each experiment containing the 4 different circular particulate stains (Clay ground soil, Standard clay, Red pottery clay, Tennis court clay; all 4 stains on one polyester fabric, 1 of those fabrics per wash) was repeated 6 times in total (2 repetitions per Launder-O-Meter, 3 separate Launder-O-Meter experiments), and the obtained data was used to calculate the average delta E value.
By using these delta E values, the so-called "standardized cleaning performance” (delta delta E) has been calculated for each individual stain. The "standardized cleaning performance” (delta delta E) is the difference of the performance of the laundry detergent including the inventive polymer, or the comparative polymer, respectively, vs. the laundry detergent without any alkoxylated polymer, or comparative polymer, respectively.
Table 2 shows the washing test conditions and Table 3 summarizes the obtained standardized cleaning performance on particulate stains. The standardized cleaning performance shown in Table 3 is the sum of the standardized cleaning performance of all 4 particulate stains. The bigger the sum of the delta delta E value, the bigger the positive contribution of the inventive polymers or the comparative polymer, respectively, vs. the laundry detergent without any inventive polymer or comparative polymer, respectively, on the cleaning performance.

*) All data are referring to the active ingredient, independent of the respective product form. Ref. 1 is as defined above.
Test results:
A value >2 (sum delta delta E) means that the respective polymer exhibits a directional and visible contribution to the overall cleaning performance of the respective detergent formulation; any value >4 (sum delta delta E) means that the respective polymer exhibits even a significant contribution to the overall cleaning performance, i.e., the respective polymer leads to a significant improvement of the formulation.

To determine the primary detergency, the cleaning performance on 8 different oily/fatty stains on cotton and polycotton fabrics (CFT, Vlaardingen, The Netherlands) was measured by determining the color difference (delta E) between the stains before and after wash using a reflectometer (Mach5 plus, a multi area color measurement instrument from ColourConsult). Each experiment containing the 8 different oily/fatty stains (Butterfat, Lard, Soybean Oil, Cocoa, Lipstick, Surfactant-sensitive soil, Sebum Bey and Chocolate Mousse) was repeated 3 times, and the obtained data was used to calculate the average delta E value.
By using these delta E values, the so-called "standardized cleaning performance” (delta delta E) has been calculated for each individual stain. The "standardized cleaning performance” (delta delta E) is the difference of the performance of the laundry detergent including the inventive polymer, or the comparative polymer, respectively, vs. the laundry detergent without any inventive polymer, or comparative polymer, respectively.

The application tests were carried out in the base liquid laundry detergent without any polymer (LLD.1) described in Table 1 to determine the impact of the inventive polymers on the primary cleaning performance. The standardized cleaning performance shown in Table 5 is the sum of the standardized cleaning performance of all 8 stains. The bigger the sum of the delta delta E value, the bigger the positive contribution of the inventive polymers or the comparative polymer, respectively, vs. the laundry detergent without any inventive polymer or comparative polymer, respectively, on the cleaning performance.
