     Furthermore, the present invention is directed to polymers useful for such compositions, and to a process for making such polymers. 
     Laundry detergents have to fulfil several requirements. They need to remove all sorts of soiling from laundry, for example all sorts of pigments, clay, fatty soil, and dyestuffs including dyestuff from food and drinks such as red wine, tea, coffee, and fruit including berry juices. Laundry detergents also need to exhibit a certain storage stability. Especially laundry detergents that are liquid or that contain hygroscopic ingredients often lack a good storage stability, e.g. enzymes tend to be deactivated. 
     Fatty soilings are still a challenge in laundering. Although numerous suggestions for removal have been made—polymers, enzymes, surfactants—solutions that work well are still of interest. It has been suggested to use a lipase to support fat removal but many builders—especially in liquid laundry detergents—do not work well with lipase. 
     It was therefore an objective to provide a detergent composition that fulfils the requirements discussed above. It was further an objective to provide ingredients that fulfil the above requirements, and it was an objective to provide a process to make such ingredients and detergent compositions. 
     Accordingly, the compositions defined at the outset have been found, hereinafter also referred to as inventive compositions or compositions according to the present invention.

The average molecular weight may be determined, e.g., by gel permeation chromatography (GPC) in tetrahydrofuran (THF) as mobile phase, with linear polymethyl methacrylate (“PMMA”) as standard. 
     In one embodiment of the present invention, polymer (A) has a molecular weight distribution M w /M n  in the range of from 1.1 to 2.5.

     In one embodiment of the present invention, polymer (A) has an OH value, measured according to DIN 53240 (2013), in the range of from 20 to 650, preferably 30 to 100 mg KOH/g polymer (A).

     Polymer (A) further comprises 
     (b) polyalkylene oxide chains. 
     Said polyalkylene oxide side chains may be derived from C 2 -C 4 -alkylene oxide. Examples of C 2 -C 4 -alkylene oxides are ethylene oxide (“EO”), propylene oxide (“PO”), butylene oxide (“BuO”), and mixtures of at least two of the foregoing, for example ethylene oxide and propylene oxide or ethylene oxide and butylene oxide. Preferred are propylene oxide and ethylene oxide, more preferred is ethylene oxide. 
     In one embodiment of the present invention, the weight ratio of core (a) to polyalkylene oxide chains (b) in polymer (A) is in the range of from 1 to 100 up to 1 to 2, preferred are 1 to 40 up to 1 to 3. 
     In one embodiment of the present invention, inventive compositions comprise at least one enzyme. Enzymes are identified by polypeptide sequences (also called amino acid sequences herein). The polypeptide sequence specifies the three-dimensional structure including the “active site” of an enzyme which in turn determines the catalytic activity of the same. Polypeptide sequences may be identified by a SEQ ID NO. According to the World Intellectual Property Office (WIPO) Standard ST.25 (1998) the amino acids herein are represented using three-letter code with the first letter as a capital or the corresponding one letter. 
     Any enzyme according to the invention relates to parent enzymes and/or variant enzymes, both having enzymatic activity. Enzymes having enzymatic activity are enzymatically active or exert enzymatic conversion, meaning that enzymes act on substrates and convert these into products. The term “enzyme” herein excludes inactive variants of an enzyme. 
     A “parent” sequence (of a parent protein or enzyme, also called “parent enzyme”) is the starting sequence for introduction of changes (e.g. by introducing one or more amino acid substitutions, insertions, deletions, or a combination thereof) to the sequence, resulting in “variants” of the parent sequences. The term parent enzyme (or parent sequence) includes wild-type enzymes (sequences) and synthetically generated sequences (enzymes) which are used as starting sequences for introduction of (further) changes. 
     The term “enzyme variant” or “sequence variant” or “variant enzyme” refers to an enzyme that differs from its parent enzyme in its amino acid sequence to a certain extent. If not indicated otherwise, variant enzyme “having enzymatic activity” means that this variant enzyme has the same type of enzymatic activity as the respective parent enzyme. 
     In describing the variants of the present invention, the nomenclature described as follows is used: 
     Amino acid substitutions are described by providing the original amino acid of the parent enzyme followed by the number of the position within the amino acid sequence, followed by the substituted amino acid. Amino acid deletions are described by providing the original amino acid of the parent enzyme followed by the number of the position within the amino acid sequence, followed by *. Amino acid insertions are described by providing the original amino acid of the parent enzyme followed by the number of the position within the amino acid sequence, followed by the original amino acid and the additional amino acid. For example, an insertion at position 180 of lysine next to glycine is designated as “Gly180GlyLys” or “G180GK”. In cases where a substitution and an insertion occur at the same position, this may be indicated as S99SD+S99A or in short S99AD. In cases where an amino acid residue identical to the existing amino acid residue is inserted, degeneracy in the nomenclature arises. If for example a glycine is inserted after the glycine in the above example this would be indicated by G180GG. Where different alterations can be introduced at a position, the different alterations are separated by a comma, e.g. “Arg170Tyr, Glu” represents a substitution of arginine at position 170 with tyrosine or glutamic acid. Alternatively different alterations or optional substitutions may be indicated in brackets e.g. Arg170[Tyr, Gly] or Arg170{Tyr, Gly}; or in short R170 [Y,G] or R170 {Y, G}; or in long R170Y, R170G. 
     Enzyme variants may be defined by their sequence identity when compared to a parent enzyme. Sequence identity usually is provided as “% sequence identity” or “% identity”. For calculation of sequence identities, in a first step a sequence alignment has to be produced. According to this invention, a pairwise global alignment has to be produced, meaning that two sequences have to be aligned over their complete length, which is usually produced by using a mathematical approach, called alignment algorithm. According to the invention, the alignment is generated by using the algorithm of Needleman and Wunsch (J. Mol. Biol. (1979) 48, p. 443-453). Preferably, the program “NEEDLE” (The European Molecular Biology Open Software Suite (EMBOSS)) is used for the purposes of the current invention, with using the programs default parameter (gap open=10.0, gap extend=0.5 and matrix=EBLOSUM62). 
     According to this invention, the following calculation of %-identity applies: %-identity=(identical residues/length of the alignment region which is showing the respective sequence of this invention over its complete length)*100. 
     According to this invention, enzyme variants may be described as an amino acid sequence which is at least n % identical to the amino acid sequence of the respective parent enzyme with “n” being an integer between 10 and 100. In one embodiment, variant enzymes are at least 70%, at least 75%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% identical when compared to the full-length amino acid sequence of the parent enzyme, wherein the enzyme variant has enzymatic activity. 
     “Enzymatic activity” means the catalytic effect exerted by an enzyme, which usually is expressed as units per milligram of enzyme (specific activity) which relates to molecules of substrate transformed per minute per molecule of enzyme (molecular activity). Variant enzymes may have enzymatic activity according to the present invention when said enzyme variants exhibit at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at 10 least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100% of the enzymatic activity of the respective parent enzyme. 
     In one embodiment, enzyme is selected from hydrolases, preferably from proteases, amylases, lipases, cellulases, and mannanases. 
     In one embodiment of the present invention, inventive compositions comprise
         (B) at least one hydrolase, hereinafter also referred to as hydrolase (B), preferably selected from lipases, hereinafter also referred to as lipase (B).

No. 5,869,438 and are at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% similar when compared to the full length polypeptide sequence of amino acids 1-269 of SEQ ID NO: 2 of U.S. Pat.

     In one embodiment of the present invention, a combination of at least two of the foregoing lipases (B) may be used. 
     In one embodiment of the present invention, lipases (B) are included in inventive composition in such an amount that a finished inventive composition has a lipolytic enzyme activity in the range of from 100 to 0.005 LU/mg, preferably 25 to 0.05 LU/mg of the composition. A Lipase Unit (LU) is that amount of lipase which produces 1 μmol of titratable fatty acid per minute in a pH stat. under the following conditions: temperature 30° C.; pH=9.0; substrate is an emulsion of 3.3 wt. of olive oil and 3.3% gum arabic, in the presence of 13 mmol/l Ca 2+  and 20 mmol/1 NaCl in 5 mmol/l Tris-buffer. 
     In one embodiment of the present invention, inventive compositions comprise
         (D) at least one protease (D), hereinafter also referred to as protease (D).       

     In one embodiment, at least one protease (D) is selected from the group of serine endopeptidases (EC 3.4.21), most preferably selected from the group of subtilisin type proteases (EC 3.4.21.62). 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 in the context of the present invention may be selected from the group consisting of chymotrypsin (e.g., EC 3.4.21.1), elastase (e.g., EC 3.4.21.36), elastase (e.g., 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”. The subtilisin related class of serine proteases shares a common amino acid sequence defining a catalytic triad which distinguishes them from the chymotrypsin related class of serine proteases. Subtilisins and chymotrypsin related serine proteases both have a catalytic triad comprising aspartate, histidine and serine. 
     Proteases are active proteins exerting “protease activity” or “proteolytic activity”. Proteolytic activity is related to the rate of degradation of protein by a protease or proteolytic enzyme in a defined course of time. 
     The methods for analyzing proteolytic activity are well-known in the literature (see e.g. Gupta et al. (2002), Appl. Microbiol. Biotechnol. 60: 381-395). Proteolytic activity may be determined by using Succinyl-Ala-Ala-Pro-Phe-p-nitroanilide (Suc-AAPF-pNA, short AAPF; see e.g. DelMar et al.

     Preferably, the DMC catalyst used for step (γ), based on polycondensate obtained in step (β), is from 5 to 2000 ppm (i.e. mg of catalyst per kg of product), preferably less than 1000 ppm, in particular less than 500 ppm, particularly preferably less than 100 ppm, for example less than 50 ppm or 35 ppm, particularly preferably less than 25 ppm; ppm referring to mass-ppm (parts per million) of polycondensate obtained in step (β). 
     Step (γ) may be carried out in bulk, embodiment (i), or in an organic solvent, embodiment (ii). In embodiment (i), water can be removed from the polycondensate obtained in step (β). Such water removal can be done by heating to a temperature in the range of from 80 to 150° C. under a reduced pressure in the range of from 0.01 to 0.5 bar and distilling off the water. 
     In one embodiment of the present invention, step (γ) is carried out at a reaction temperature in the range of from 70 to 200° C. and preferably from 100 to 180° C. 
     In one embodiment of the present invention, step (γ) is carried out once per synthesis of inventive polymer (A). In an alternative embodiment, step (γ) is carried out several time, for example up to four times per synthesis of an inventive polymer (A), for example with the same or preferably with different C 2 -C 4 -alkylene oxides. It is, for example, possible to subject a polycondensate obtained in step (β) to a first alkoxylation (γ1) with ethylene oxide and to subject the product from step (γ1) to a second alkoxylation (γ2), for example with propylene oxide. 
     In one embodiment of the present invention, step (γ) is carried out at a pressure of up to 10 bar and in particular up to 8 bar, for example 1 to 8 bar. 
     In one embodiment of the present invention, the reaction time of step (γ) is generally in the range of from 0.5 to 12 hours. 
     Examples of suitable organic solvents for embodiment (ii) of step (γ) are nonpolar and polar aprotic organic solvents. Examples of particularly suitable nonpolar aprotic solvents include aliphatic and aromatic hydrocarbons such as hexane, cyclohexane, toluene and xylene. Examples of particularly suitable polar aprotic solvents are ethers, in particular cyclic ethers such as tetrahydrofuran and 1,4-dioxane, furthermore N,N-dialkylamides such as dimethylformamide and dimethylacetamide, and N-alkyllactams such as N-methylpyrrolidone. It is as well possible to use mixtures of at least two of the above organic solvents. Preferred organic solvents are xylene and toluene. 
     In embodiment (ii), the solution obtained in the first step, before or after addition of catalyst and solvent, is dewatered before being subjected to alkylene oxide, said water removal advantageously being done by removing the water at a temperature in the range of from 120 to 180° C., preferably supported by a stream of nitrogen. The subsequent reaction with the alkylene oxide may be effected as in embodiment (i). In embodiment (i), alkoxylated polyalkylenimines according to the invention is obtained directly in bulk and may be dissolved in water, if desired. In embodiment (ii), for work-up organic solvent is typically replaced by water. Alkoxylated polyalkylenimines (B) according to the invention may alternatively be isolated in bulk. 
     An—optional—step of work-up may include the deactivation of catalyst used in step (γ), in the case of basic catalysts by neutralization. 
     The inventive process does not require bleaching steps or reductive removal of impurities. 
     The present invention is further illustrated by working examples.

     The total level of cleaning was evaluated using color measurements. Reflectance values of the stains on the monitors were measured using a sphere reflectance spectrometer (SF 500 type from Datacolor, USA, wavelength range 360-700 nm, optical geometry)d/8° with a UV cutoff filter at 460 nm. In this case, with the aid of the CIE-Lab color space classification, the brightness L*, the value a* on the red—green color axis and the b* value on the yellow—blue color axis, were measured before and after washing and averaged for the respective stains of the monitor. The change of the color value (Delta E, ΔE) value, defined and calculated automatically by the evaluation color tools on the following formula, 
       Δ E*   ab =√{square root over (Δ L*   2   +Δa*   2   +Δb*   2 )}
 
     is a measure of the achieved cleaning effect. All experiments were repeated three times to provide a representative average number. 
     Higher Delta E values show better cleaning. For each stain, a difference of 1 unit can be detected visually by a skilled person. A non-expert can visually detect 2 units easily. The ΔE values of the formulations for the 4, 8 and 11 stains of correspondingly M1 and M2 plus M3 and for some selected single stains are shown in Table 5.

     In the tests, a cleaning performance benefit can be seen for both ΔE of M1 and M2 plus M3 monitors with the inventive polyester amines. A higher benefit on fat-containing stains like sebum and lipstick (wfk20D and EMPA141/2) can be seen with the polymers that are first ethoxylated and then propoxylated (γ.2, γ.4, γ.6, γ.8, γ.10).

     II.2.3 Manufacture of Inventive Formulation HSC.3 
     A 250 ml vessel was charged with 80 g water. Then, 6 g aqueous solution of NaOH (50%) and 8 g butylenediglycol (BDG) were added, followed by 5 g of a 41% by weight solution of MGDA-Na 3 , 2 g of a 50% aqueous solution of (IV.1) and 2 g of inventive polymer (A.5.2). Homogenisation was achieved with moderate stirring (magnetic) at ambient temperature over a period of time of 5 minutes. Inventive formulation HSC.3 was obtained. 
     II.2.4 Manufacture of Inventive Formulation HSC.4 
     A 250 ml vessel was charged with 80 g water. Then, 6 g aqueous solution of NaOH (50%) and 8 g butylenediglycol (BDG) were added, followed by 5 g of a 41% by weight solution of MGDA-Na 3 , 2 g of a 50% aqueous solution of (IV.1) and 2 g of inventive polymer (A.6.2). Homogenisation was achieved with moderate stirring (magnetic) at ambient temperature over a period of time of 5 minutes. Inventive formulation HSC.4 was obtained. 
     Performance was evaluated with respect to the cleaning performance at ambient temperature on stainless-steel surfaces. 
     Test soil: a greasy soil was prepared by mixing 25.0% butter, 25.0% lard, 25.0% margarine, 20.0% ketchup, 2.5% mustard and 2.5% potato starch at 40 to 45° C. under continuous stirring. A greasy soil was obtained. 
     Stainless steel plates (15×10 cm) were pre-cleaned with ethanol, and then their weight was determined. About 1.5 g of greasy soil was applied evenly to each plate with a roller. Then, the plates were heated in an oven to 200° C. for two hours. Then, the plates were allowed to cool down to ambient temperature and stored for two hours. Finally, the cleaning tests were performed. 
     2 g of inventive formulations/or comparative formulation, respectively, were evenly sprayed onto the soiled stainless-steel plates through a trigger sprayer and allow to act for 2 minutes. In addition, the soiled surface of the plate was wiped with a cellulose-type wet sponge (without applying any force). 
     The evaluation of the dirt removal was performed visually and refers to an average value of three experiments:
     1 No removal   2 Weak removal (10-30% surface cleaned)   3 Average removal (40-70% surface cleaned)   4 Good removal (70-90% surface cleaned)   5 Excellent removal (&gt;90% surface cleaned)   

     Percentages refer to the surface.

     III. Biodegradation Tests 
     General: the tests were carried out in accordance with the OECD Guidelines. According to the OECD guidelines a test is valid if:
     1. The reference reaches 60% within 14 days.   2. The difference of the extremes of the test replicates by the end of the test is less than 20%.   3. Oxygen uptake of inoculum blank is 20-30 mg 02/I and must not be greater than 60 mg 02/I.   4. The pH value measured at the end of the test must be between 6 and 8.5.   

     Description of the test method used in the context of the present invention: 
     Biodegradation in sewage was tested in triplicate using the OECD 301 F manometric respirometry method. OECD 301F is an aerobic test that measures biodegradation of a sewage sample by measuring the consumption of oxygen. To a measured volume of sewage, 100 mg/L test substance, which is the nominal sole source of carbon, was added along with the inoculum (aerated sludge taken from the municipal sewage treatment plant, Mannheim, Germany). This sludge was stirred in a closed flask at a constant temperature (25° C.) for 28 days. The consumption of oxygen is determined by measuring the change in pressure in the closed flask using an Oxi TopC. Carbon dioxide evolved was absorbed in a solution of sodium hydroxide. Nitrification inhibitors were added to the flask to prevent consumption 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 a 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/glutamic acid is run along with the test samples for each cabinet as reference. 
     Calculations: 
     Theoretical oxygen demand: Amount of 02 required to oxidize a compound to its final oxidation products. This is calculated using the elemental analysis data. 
     % Biodegradation 
     Experimental O 2  uptake x 100 and divided by the theoretical oxygen demand 
     The results of biodegradability tests are summarized in Table 8.
