DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Definition. As used herein, the article "a" refers to one and to more than one and does not necessarily limit the noun it refers to to the grammatical category of singular.
[0015] As used herein, the terms "about" and "at or about", when used to modify an amount or value, refer to an approximation of an amount or value that is greater than or less than the exact amount or value described in the claim or the present specification. The exact value of the approximation is determined by what a person skilled in the art would recognize as a suitable approximation of the exact value. As used herein, the term conveys that a similar value not exactly described in the claim or the present specification may produce results or effects equivalent to those described in the claim or the present specification, which a person skilled in the art would recognize as acceptable as those produced by similar values.
[0016] The terms "volume percent," "volume percentage," "vol%," and "v / v%" are used interchangeably herein. The volume percent of a solute in a solution can be determined by the formula: [(volume of solute) / (volume of solution)]×100%.
[0017] The terms "weight percent," "weight percentage (wt%)," and "weight-to-weight percent (% w / w)" are used interchangeably herein. Weight percent refers to the percentage of a material by mass when contained in a composition, mixture, or solution.
[0018] As used herein, "weight average molecular weight" or "Mw" means Mw = ΣN i M i 2 / ΣN i M i , [where M i is the molecular weight of the chain, and N iwhere m is the number of chains of that molecular weight. Weight average molecular weight can be determined by techniques such as static light scattering, gas chromatography (GC), high performance liquid chromatography (HPLC), gel permeation chromatography (GPC), small angle neutron scattering, X-ray scattering, and sedimentation velocity.
[0019] As used herein, "number average molecular weight" or "Mn" refers to the statistical average molecular weight of all polymer chains in a sample. The number average molecular weight is M n =ΣN i M i / ΣN i [In the formula, M i is the molecular weight of the chain, and N i where m is the number of chains of that molecular weight. The number average molecular weight of a polymer can be determined by techniques such as gel permeation chromatography, viscosity measurements via the Mark-Houwink equation, and collisional methods such as vapor pressure osmometry, end group determination, or proton NMR.
[0020] The terms "increased," "enhanced," and "improved" are used interchangeably herein. These terms may refer, for example, to an amount or activity that is at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 125%, 150%, 175%, or 200% (or any integer between 1% and 200%) greater than the compared amount or activity.
[0021] The terms "poly alpha-1,3-glucan", "alpha-1,3-glucan polymer" and "glucan polymer" are used interchangeably herein. Poly alpha-1,3-glucan is a polymer that includes glucose monomer units linked together by glycosidic bonds, and at least about 50% of the glycosidic bonds are alpha-1,3-glycosidic bonds. Poly alpha-1,3-glucan is a type of polysaccharide. The structure of poly alpha-1,3-glucan can be illustrated as follows:
[0022] [ka]
[0023] Poly alpha-1,3-glucan that can be used to prepare the poly alpha-1,3-glucan ester compounds described herein can be prepared using chemical methods. Alternatively, the poly alpha-1,3-glucan can be prepared by extraction from various organisms, such as fungi, that produce poly alpha-1,3-glucan. Alternatively, poly alpha-1,3-glucan can be enzymatically produced from sucrose using one or more glucosyltransferase (gtf) enzymes (e.g., gtfJ), as described, for example, in U.S. Patent Nos. 7,000,000, 9,080,195, and 8,642,757 (all three of which are incorporated herein by reference).
[0024] The terms "glucosyltransferase enzyme", "gtf enzyme", "gtf enzyme catalyst", "gtf" and "glucansucrase" are used interchangeably herein. The activity of the gtf enzyme herein catalyzes the reaction of sucrose substrate to the product poly alpha-1,3-glucan and fructose. Other products (by-products) of the gtf reaction may include glucose (when glucose is hydrolyzed from the glucosyl-gtf enzyme intermediate complex), various soluble oligosaccharides (DP2-DP7), and leucrose (when the glucose of the glucosyl-gtf enzyme intermediate complex is linked to fructose). Leucrose is a disaccharide containing glucose and fructose linked by an alpha-1,5 bond. Wild-type glucosyltransferase enzymes generally include (from the N-terminus to the C-terminus) a signal peptide, a variable domain, a catalytic domain, and a glucan-binding domain. According to the CAZy (Carbohydrate-Active EnZymes) database (Cantarel et al., Nucleic Acids Res. 37:D233-238, 2009), gtf in this specification is classified into glycoside hydrolase family 70 (GH70).
[0025] The percentage of glycosidic bonds between glucose monomer units of the poly alpha-1,3-glucan used to prepare the poly alpha-1,3-glucan ester compounds described herein that are alpha-1,3 is at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% (or any integer value between 50% and 100%). Thus, in such embodiments, the poly alpha-1,3-glucan has less than about 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, 1%, or 0% (or any integer value between 0% and 50%) of glycosidic bonds that are not alpha-1,3.
[0026] The poly alpha-1,3-glucan used to prepare the poly alpha-1,3-glucan ester compounds described herein is preferably linear / unbranched. In certain embodiments, the poly alpha-1,3-glucan has no branch points or has less than about 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% branch points as a percentage of glycosidic bonds in the polymer. Examples of branch points include alpha-1,6 branch points, such as those present in mutan polymers.
[0027] The terms "glycosidic bond" and "glycosidic linkage" are used interchangeably herein and refer to a type of covalent bond that binds a carbohydrate (sugar) molecule to another group, such as another carbohydrate. As used herein, the term "α-1,3-glycosidic bond" refers to a type of covalent bond that connects α-D-glucose molecules to each other through carbons 1 and 3 in adjacent α-D-glucose rings. This bond is shown in the structure of poly α-1,3-glucan above. As used herein, "α-D-glucose" is referred to as "glucose."
[0028] The terms "poly alpha-1,3-glucan ester compound," "poly alpha-1,3-glucan ester," and "poly alpha-1,3-glucan ester derivative" are used interchangeably herein. Poly alpha-1,3-glucan compounds have the structure:
[0029] [ka] [In the formula, n is at least 6; R 1 is independently selected from the group consisting of H and an ester modifying group, wherein the ester modifying group is selected from the group consisting of (a), (b), (c) or a combination of the following: (a) acetyl, (b) an aryl ester group, (c) an acyl group,
[0030] [ka] [wherein a is independently 6 to 24], and (d) an acyl group,
[0031] [ka] [In the formula, R 3 can be independently selected from an H atom, a linear alkyl group, a branched alkyl group, a cyclic alkyl group, and an aryl group containing 1 to 24 carbon atoms, and (d) is different from (a) and (c); and (e)-CO-C x -COOR 3 [Wherein, -C of the second acyl group x The - moiety contains a chain of 2 to 24 carbon atoms, and R 3 contains a chain of 1 to 24 carbon atoms; with the proviso that when (a) is present, at least one other ester group (b), (c), (d) and / or (e) is present; The degree of substitution of the ester group is 0.001 to 3.
[0032] The poly alpha-1,3-glucan ester compounds disclosed herein are synthetic, man-made compounds.
[0033] The poly α-1,3-glucan ester compound has the substructure C G The term "ester" is used herein because it contains -O-CO-C-, and "-C G "--" represents carbon 2, 4, or 6 of the glucose monomer unit of the poly alpha-1,3-glucan ester compound, and the "--CO--C--" in the formula is contained in an acyl group.

[0068] The ester group modification is (a) acetyl, (b) an aryl ester group, and (c) Acyl group
[0069] [ka] In some cases, a combination of the formula: wherein a is independently 6 to 24 is preferable.
[0070] The ester group modification of the poly α-1,3-glucan ester compound is (a) acetyl, and (b) an aryl ester group.
[0071] The ester group modification of the poly α-1,3-glucan ester compound is (a) acetyl, and (b) benzoyl.
[0072] The poly α-1,3-glucan ester compound has a degree of substitution of the ester group modification of 0.001 to 3, preferably 0.005 to 2, more preferably 0.01 to 1, and most preferably 0.02 to 0.8.
[0073] It may be preferable that each a is independently 9 to 16.
[0074] The poly alpha-1,3-glucan derivatives disclosed herein comprise a poly alpha-1,3-glucan backbone that is randomly substituted with ester modifications along the polysaccharide backbone such that the polysaccharide backbone typically comprises unsubstituted and substituted alpha-D-glucose rings. In embodiments where branching is present, the branched alpha-D-glucose rings may also be randomly substituted with ester modification groups. As used herein, the term "randomly substituted" means that the substituents on the glucose rings in the randomly substituted polysaccharide are present in a non-repeated or random manner. That is, the substitution on the substituted glucose ring may be the same or different from the substitution on a second substituted glucose ring in the polysaccharide [i.e., the substituents on different atoms of the glucose ring in the polysaccharide (which may be the same or different)], such that the overall substitution on the polymer does not have a pattern. Furthermore, the substituted glucose rings are present randomly within the polysaccharide (i.e., there is no pattern of substituted and unsubstituted glucose rings within the polysaccharide).
[0075] Depending on the reaction conditions, the poly alpha-1,3-glucan ester compounds disclosed herein may contain a poly alpha-1,3-glucan backbone that is "non-randomly" substituted with ester modifying groups along the polysaccharide backbone. If branching is present, the branched alpha-D-glucose rings may contain disproportionately more substitutions than the backbone glucose monomer units via alpha-1,3-glycosidic bonds. Also, under certain reaction conditions, modifications may occur in blocks in the polysaccharide.
[0076] Also, depending on the reaction conditions, the glucose carbon positions 1, 2, 3, 4, and 6 of the poly alpha-1,3-glucan backbone may be "unbalanced" substituted. For example, more substitution may occur at carbon position 6 because the -OH group is a primary hydroxyl group and may be in a less sterically hindered environment, and this OH group may be more reactive under certain reaction conditions. Under other reaction conditions, the OH groups at carbon positions 1, 2, 3, or 4 may be more reactive.
[0077] Without being bound by theory, it is believed that a lower degree of substitution increases the likelihood that "unbalanced" and "non-random" types of substitution are present.

The composition may further comprise at least one of surfactants, enzymes, detergent builders, complexing agents, polymers, soil release polymers, surfactant enhancing polymers, bleaching agents, bleach activators, bleach catalysts, fabric conditioners, clays, suds boosters, suds suppressors, corrosion inhibitors, soil suspending agents, soil redeposition inhibitors, dyes, bactericides, anti-tarnish agents, optical brighteners, fragrances, saturated or unsaturated fatty acids, dye transfer inhibitors, chelating agents, hueing dyes, calcium cations, magnesium cations, visual signaling components, defoamers, structurants, thickeners, anti-caking agents, starches, sands, gelling agents, or combinations thereof.

If an enzyme is included, it may be present in the product at about 0.0001-0.1% by weight of active enzyme, based on the total weight of the composition. In other embodiments, the enzyme may be present at about 0.01-0.03% by weight (e.g., calculated as pure enzyme protein) of active enzyme, based on the total weight of the composition. In some embodiments, a combination of two or more enzymes may be used in the composition. In some embodiments, the two or more enzymes are cellulase and one or more of a protease, hemicellulase, peroxidase, lipolytic enzyme, xylanase, lipase, phospholipase, esterase, perhydrolase, cutinase, pectinase, pectate lyase, mannanase, keratinase, reductase, oxidase, phenol oxidase, lipoxygenase, ligninase, pullulanase, tannase, pentosanase, malanase, β-glucanase, arabinosidase, hyaluronidase, chondroitinase, laccase, metalloproteinase, amadoriase, glucoamylase, arabinofuranosidase, phytase, isomerase, transferase, amylase, or a combination thereof.
[0080] In some embodiments, the composition may include one or more enzymes, each enzyme being present at about 0.00001% to about 10% by weight based on the total weight of the composition. In some embodiments, the composition may also include each enzyme at a concentration of about 0.0001% to about 10% by weight, about 0.001% to about 5% by weight, about 0.001% to about 2% by weight, or about 0.005% to about 0.5% by weight based on the total weight of the composition.
[0081] Cellulases may have endocellulase activity (EC 3.2.1.4), exocellulase activity (EC 3.2.1.91), or cellobiase activity (EC 3.2.1.21). Cellulases are "active cellulases" that are active under conditions suitable for maintaining cellulase activity, and determining such suitable conditions is within the skill of the art. In addition to being able to degrade cellulose, cellulases, in certain embodiments, can also degrade cellulose ether derivatives, such as carboxymethylcellulose.
[0082] The cellulase may be derived from any microbial source, such as bacteria or fungi. It includes chemically modified cellulases or mutant cellulases in which the protein is genetically engineered. Suitable cellulases include, for example, cellulases from the genera Bacillus, Pseudomonas, Streptomyces, Trichoderma, Humicola, Fusarium, Thielavia, and Acremonium. As another example, the cellulase may be derived from Humicola insolens, Myceliophthora thermophile, Fusarium oxysporum, Trichoderma reesei, or combinations thereof. Cellulases such as any of the above may be in a mature form lacking an N-terminal signal peptide. Commercially available cellulases useful herein include CELLUSOFT®, CELLUCLEAN®, CELLUZYME®, and CAREZYME® (Novozymes A / S); CLAZINASE® and PURADAX® HA and REVITALENZ™ (DuPont Industrial Biosciences), BIOTOUCH® (AB ENZYMES); and KAC-500(B)® (Kao).
[0083] Alternatively, the cellulases herein may be produced by any means known in the art, for example, the cellulases may be recombinantly produced in a heterologous expression system, such as a microbial or fungal heterologous expression system. Examples of heterologous expression systems include bacterial (e.g., Escherichia coli, Bacillus spp.) and eukaryotic systems. Eukaryotic systems may use yeast (e.g., Pichia spp., Saccharomyces spp.) or fungal (e.g., Trichoderma spp., such as T. reesei, Aspergillus spp., such as A. niger) expression systems.
[0084] In certain embodiments, the cellulase may be thermostable. Thermostability of a cellulase refers to the ability of the enzyme to retain activity after exposure to high temperatures (e.g., about 60-70°C) for a period of time (e.g., about 30-60 minutes). Thermostability of a cellulase may be measured by its half-life (t1 / 2), given in minutes, hours, or days during which half of the cellulase activity is lost under defined conditions.
[0085] In certain embodiments, the cellulase may be stable over a wide range of pH values (e.g., neutral or alkaline pH, such as from about pH 7.0 to about 11.0), and such enzymes may remain stable under such pH conditions for a period of time (e.g., at least about 15 minutes, 30 minutes, or 1 hour).
[0086] At least one, two, or more cellulases may be included in the composition. The total amount of cellulase in the composition herein is typically an amount suitable for the purpose of using the cellulase in the composition ("effective amount"). For example, an effective amount of cellulase in a composition intended to improve the feel and / or appearance of a cellulose-containing fabric is an amount that produces a measurable improvement in the feel of the fabric (e.g., improved smoothness and / or appearance of the fabric, removal of pills and microfibers that tend to reduce the crispness of the fabric's appearance). As another example, an effective amount of cellulase in a fabric stonewashing composition herein is an amount that produces a desired effect (e.g., making seams and fabric panels look worn and faded). The amount of cellulase in the composition herein may also depend, for example, on the process parameters (e.g., equipment, temperature, time, etc.) in which the composition is used and the cellulase activity. The effective concentration of cellulase in the aqueous composition in which the fabric is treated can be easily determined by one of ordinary skill in the art. In fabric care processes, cellulases can be present in the aqueous composition (e.g., wash liquor) in which the fabrics are treated at concentrations, for example, from a minimum of about 0.01-0.1 ppm total cellulase protein, or about 0.1-10 ppb total cellulase protein (e.g., less than 1 ppm), to a maximum of about 100, 200, 500, 1000, 2000, 3000, 4000, or 5000 ppm total cellulase protein.

[0116] Working Example Unless otherwise stated, all components were available from Sigma-Aldrich (St. Louis, Missouri) and were used as received.
[0117] As used herein, "Comp. Ex." means comparative example; "Ex." means "Example," "std dev" means standard deviation, "g" means grams, "mL" means milliliter, "uL" means microliter, "wt" means weight, "L" means liter, "min" means minute, "kDa" means kilodalton, and "PES" means polyethersulfone.
[0118] Method for determining anomeric bonds by NMR spectroscopy The glycosidic linkages in the water-soluble oligosaccharide and polysaccharide products synthesized by glucosyltransferase GTF8117 and the α-1,2 branching enzyme were 1 The chromatograms were determined by H NMR (nuclear magnetic resonance spectroscopy). Dry oligosaccharide / polysaccharide polymers (6 mg-8 mg) were dissolved in 0.7 mL of 1 mM DSS (4,4-dimethyl-4-silapentane-1-sulfonic acid; NMR reference standard) solution in DO. The samples were stirred overnight at ambient temperature. 525 uL of the clear homogenous solution was transferred to a 5 mm NMR tube. 2D 1 H, 13 C homo / heteronuclear NMR experiments were used to identify AGU (anhydroglucose unit) linkages. Data were collected at 20 °C and processed on a Bruker Advance III NMR spectrometer operating at either 500 MHz or 600 MHz. The system is equipped with a proton-optimized, helium-cooled cryoprobe. 1D 1 The distribution of glycosidic linkages was quantified using H NMR spectroscopy, which confirmed that the polysaccharide backbone was predominantly α-1,6. This reflects the ratio of the integrated intensity of the NMR resonance representing each individual linkage type divided by the integrated intensity of the sum of all peaks representing glucose linkages, multiplied by 100.
[0119] Methods for evaluating the whiteness performance of polymers Whiteness maintenance, also called whiteness retention, is the ability of a detergent to prevent white items from losing whiteness when washed in the presence of soil. White clothes may appear dirty / dull over time as soil is removed from the soiled clothes and suspended in the wash water, and these soils may then be redeposited on the clothes, so the clothes lose whiteness every time they are washed. The whiteness effect of the presently disclosed polymers is evaluated using an automatic mini washer with five pots. SBL2004 test soil stips supplied by WFKTestgewebe GmbH are used to simulate consumer soil levels (a mixture of body soil, food, grime, grass, etc.). On average, 8g of soil is loaded per SBL2004 strip. The white fabric swatches in Table 2 below purchased from WFK are used as whiteness tracers. Before the wash test, the L, a, B values of all whiteness tracers are measured using a Konica Minolta CM-3610D spectrophotometer.
[0120] [Table 5] Notes: * WI(A)-Light source A (indoor lighting) ** WI(D65)-Light source D65 (outdoor lighting)
[0121] Three wash cycles are required to complete the test. Cycle 1: The desired amount of base detergent is completely dissolved by mixing with 7.57 L of water (of the specified hardness) in the tube of each mini washer. 3.5 SBL2004 strips (approximately 28 g of soil) of each fabric type and three whiteness tracers (internal replicates) are washed in the mini washer under the specified conditions, rinsed and then dried. Cycle 2: The brightness tracer is washed again with a new set of SBL2004 sheets and dried. All other conditions remain the same as in cycle 1. Cycle 3: The brightness tracer is washed again with a new set of SBL2004 sheets and dried. All other conditions remain the same as in cycle 1.
[0122] After cycle 3, all the whiteness tracers are dried and then measured again using a Konica Minolta CM-3610 D spectrophotometer. The change in whiteness index (ΔWI(CIE)) is calculated based on the L, a, b measurements before and after washing. ΔWI(CIE)=WI(CIE)(after cleaning)-WI(CIE)(before cleaning).
[0123] The mini washer has five pots, so five products can be tested in one test. Typically, in the polymer brightness performance test, one reference product containing a comparative polymer or no polymer is tested along with four products containing the polymer of the present invention, and "ΔWI vs. reference" is reported. ΔWI(CIE) vs. reference = ΔWI(CIE)(product) - ΔWI(CIE)(reference)
[0124] Methods for evaluating the cleaning effectiveness of polymers: The cleaning effectiveness of the polymers is evaluated using a Tergotometer. Some examples of test stains suitable for this test are: Standard glass, made by CFT Standard clay, made by CFT ASTM Dust Sebum, CFT Highly differentiated sebum on polycotton, made by CFT Browned Bacon on Knitted Cotton (Made with Equest Browned Bacon) Dyed bacon on knitted cotton (made using dyed bacon from Equest).
[0125] The fabrics were analyzed using commercially available DigiEye software for L, a, and b values.
[0126] The inventive polymer stock solution in deionized water was prepared to dispense the desired 5 mL aliquots. To make 1 L of test solution, 5 mL of the polymer stock solution and the desired amount of base detergent were completely dissolved by mixing with water (defined hardness) in a tergotometer pot. The washing temperature was 20°C.
[0127] The fabric washed in each tergotometer pot contained two pieces of each test stain (two internal replicas), approximately 3g of a WFK SBL2004 stain sheet, and additional knitted cotton ballast to bring the total fabric weight up to 60g.
[0128] Once all the fabrics were dropped into the tergotometer pot containing the wash liquor, the wash liquor was agitated for 12 minutes. The wash liquor was then drained and the fabrics were subjected to two 5 minute rinse steps before being drained and spun dry. The washed stains were allowed to dry in an air flow cabinet and then analyzed for L, a, b values using commercially available DigiEye software.
[0129] This procedure was repeated three more times for a total of four external replicas.
[0130] The Stain Removal Index (SRI) is calculated from the L, a, and b values using the formula shown below. The higher the SRI, the better the stain removal. SRI=100 * ((ΔE b -ΔE a ) / ΔE b ) ΔE b =√((L c -L b ) 2 +(a c -a b ) 2 +(b c -b b ) 2 ) ΔEa =√((L c -L a ) 2 +(a c -a a ) 2 +(b c -b a ) 2 ) Subscript "b" indicates data for stains before cleaning Subscript "a" indicates data for stains after washing The subscript "c" indicates data for unstained fabrics.
[0131] Polymer 1 of the invention: Modification of poly α-1,3 glucan with benzoyl chloride in dimethylacetamide To a stirred, jacketed 1-liter resin kettle were added 550 g dimethylacetamide, 37 g poly alpha-1,3 glucan polymer (backbone MW: 120K), and 26 g calcium chloride dihydrate. The contents were held at 70°C for 2.25 hours, after which the poly alpha-1,3 glucan and calcium chloride dihydrate were placed into solution. The contents were heated to 78°C, after which 21 mL of benzoyl chloride was fed over 1.5 minutes. The solution was held at 80-84°C for 2 hours. Heat to the reactor was then stopped and a vacuum was pulled to facilitate evaporative cooling of the reactor contents. After removing 65 g DMAc overhead, the reactor pressure was returned to atmospheric pressure and 443 g of the reaction solution was poured into acetone to precipitate the solids, which were then slurried twice with 1 liter of methanol, filtered, and dried overnight to obtain the product. NMR analysis of the product indicated that the degree of substitution for the benzoate content was 0.20 and the degree of substitution for the acetate content was 0.08.
