[0022] [ka]

[0023] Poly-α-1,3-glucans that can be used to prepare the poly-α-1,3-glucan ester compounds described herein can be prepared by chemical methods. Alternatively, such poly-α-1,3-glucans can be prepared by extraction from various organisms, such as fungi, that produce poly-α-1,3-glucans. Alternatively, poly-α-1,3-glucans can be enzymatically produced from sucrose using one or more glucosyltransferase (GTF) enzymes (e.g., GTFJ), as described, for example, in U.S. Patents 7,000,000, 9,080,195, and 8,642,757 (all three of which are incorporated herein by reference).

Leucrose is a disaccharide containing glucose and fructose linked by an α-1,5 linkage. Wild-type glucosyltransferase enzymes generally contain a signal peptide, a variable domain, a catalytic domain, and a glucan-binding domain (from N-terminus to C-terminus). In this specification, gtf is classified as belonging to the glycoside hydrolase family 70 (GH70) according to the CAZy (Carbohydrate-Active Enzymes) database (Cantarel et al., Nucleic Acids Res. 37: D233-238, 2009).

[0074] The poly-α-1,3-glucan derivatives disclosed herein comprise a poly-α-1,3-glucan skeleton randomly substituted with ester modifications along the polysaccharide skeleton, such that the polysaccharide skeleton typically contains unsubstituted and substituted α-D-glucose rings. In embodiments where branching is present, the branched α-D-glucose rings may also be randomly substituted with ester-modifying groups. As used herein, the term “randomly substituted” means that substituents on the glucose rings in a randomly substituted polysaccharide are non-repeating or random. That is, substitutions on a substituted glucose ring may be identical or different from substitutions on a second substituted glucose ring in the polysaccharide [i.e., substituents on different atoms of the glucose ring in the polysaccharide (which may be identical or different)], resulting in no overall pattern of substitutions on the polymer. Furthermore, the substituted glucose rings are randomly distributed 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-α-1,3-glucan ester compounds disclosed herein may also contain a poly-α-1,3-glucan skeleton in which ester-modifying groups are "non-randomly" substituted along the polysaccharide skeleton. Where branching is present, the branched α-D-glucose ring may contain disproportionately more substitutions than the skeletal glucose monomer units via α-1,3-glycosidic bonds. Furthermore, under certain reaction conditions, modifications may exist in a block-like manner within the polysaccharide.

[0076] Furthermore, depending on the reaction conditions, the glucose carbon positions 1, 2, 3, 4, and 6 of the poly-α-1,3-glucan skeleton may be substituted in an "unbalanced" manner. For example, the -OH group at carbon position 6 is a primary hydroxyl group and may exist in an environment with less steric hindrance. This OH group may exhibit higher reactivity under certain reaction conditions, potentially leading to more substitutions at this position. Under other reaction conditions, the OH groups at carbon positions 1, 2, 3, or 4 may exhibit higher reactivity.

[0077] Without theoretical constraints, it is believed that as the degree of substitution decreases, the likelihood of "imbalanced" and "non-random" type substitutions increases.

In some embodiments, the composition may also contain each enzyme at concentrations 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 (EC3.2.1.4), exocellulase activity (EC3.2.1.91), or cellobiase activity (EC3.2.1.21). A cellulase is an "active cellulase" that is active under conditions suitable for maintaining cellulase activity, and determining such suitable conditions is within the scope of the skill of the art. In addition to being able to decompose cellulose, in certain embodiments, cellulases may also decompose cellulose ether derivatives such as carboxymethylcellulose.

[0082] Cellulases can originate from any microbial source, such as bacteria or fungi. This includes chemically modified cellulases or genetically engineered mutant cellulases. Suitable cellulases include, for example, those derived from the genera Bacillus, Pseudomonas, Streptomyces, Trichoderma, Humicola, Fusarium, Tierabia, and Acremonium. Other examples include cellulases derived from Humicola insolens, Myceliophthora thermophile, Fusarium oxysporum, Trichoderma reesei, or combinations thereof. Cellulases such as any of the above may be mature forms lacking an N-terminal signal peptide. Examples of commercially available cellulases useful in this specification 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 Corporation).

[0083] Alternatively, the cellulases described herein may be produced by any means known in the art, for example, by recombinant expression in a heterologous expression system such as a heterologous expression system of a microorganism or fungus. Examples of heterologous expression systems include bacteria (e.g., Escherichia coli, Bacillus species) and eukaryotic systems. Eukaryotic systems may be expression systems of yeast (e.g., Pichia species, Saccharomyces species) or fungi (e.g., Trichoderma species such as T. reesei, Aspergillus species such as Aspergillus niger).

[0084] In certain embodiments, cellulase can be thermally stable. Thermal stability of cellulase refers to the enzyme's ability to retain its activity after exposure to high temperatures (e.g., about 60-70°C) for a certain period of time (e.g., about 30-60 minutes). The thermal stability of cellulase can be measured by its half-life (t1 / 2), which is given as the number of minutes, hours, or days during which half of the cellulase activity is lost under specified 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 pH approximately 7.0 to approximately 11.0). Such an enzyme may remain stable under such pH conditions for a predetermined time (e.g., at least approximately 15 minutes, 30 minutes, or 1 hour).

[0086] A composition may contain at least one, two, or more cellulases. The total amount of cellulase in a composition as used herein is typically an amount suitable for the purpose for which the cellulase in the composition is used ("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., improvement in the smoothness and / or appearance of the fabric, removal of lint and microfibers that tend to reduce the sharpness of the appearance of the fabric). As another example, an effective amount of cellulase in a fabric stonewashing composition as used herein is an amount that produces the desired effect (e.g., making seams and fabric panels appear worn and faded). The amount of cellulase in a composition as used herein may also depend, for example, on the process parameters in which the composition is used (e.g., equipment, temperature, time, etc.) and the cellulase activity. The effective concentration of cellulase in the aqueous composition in which the fabric is treated can be easily determined by those skilled in the art. In the fabric care process, cellulase may be present in the aqueous composition (e.g., cleaning solution) to which the fabric is treated, at concentrations ranging from, for example, as low as about 0.01–0.1 ppm of total cellulase protein, or about 0.1–10 ppb of total cellulase protein (e.g., less than 1 ppm), to as high as about 100, 200, 500, 1000, 2000, 3000, 4000, or 5000 ppm of total cellulase protein.

[Examples]

[0108] Laundry and dish care compositions are typically suitable for (a) the care of finished textiles, washing of finished textiles, sanitizing of finished textiles, disinfection of finished textiles, detergents, stain removers, fabric softeners, fabric conditioners, stain removers or treatments of finished textiles, pre-washing and post-washing treatments, washing machine cleaning and maintenance (finished textiles are intended to include clothing and textile products), (b) the care of dishes, glasses, ceramics, pots, pans, kitchenware, cutlery, etc. in automatic dishwashers, such as detergents, pre-treatment and machine cleaning and maintenance products for both dishwashers, water used, and their contents, or (c) detergents for hand-washing dishes.

[0109] The formulations of the following examples are suitable for the present invention. The following are illustrative examples of the cleaning compositions relating to this disclosure and are not intended to be limiting.

[0110] Examples 1-7: Heavy liquid laundry detergent compositions.

[0111] [Table 1] Based on the total weight of the washing and / or treatment composition. Enzyme concentration is reported as raw material.

[0112] [Table 2]

[0113] The following are preferred water-soluble unit-dose formulations. The composition may be part of a single-chamber water-soluble unit-dose article, or it may be divided across multiple compartments to yield the following "compartment-averaged" whole article composition.

[0114] [Table 3] Examples of solid, free-flowing particulate laundry detergent compositions:

[0115] [Table 4]

[0116] Examples Unless otherwise specified, all ingredients were obtained from Sigma-Aldrich (St. Louis, Missouri) and used as obtained.

[0117] In this specification, "Comp.Ex." means comparative example; "Ex." means "example"; "std dev" means standard deviation; "g" means grams; "mL" means milliliters; "uL" means microliters; "wt" means weight; "L" means liters; "min" means minutes; "kDa" means kilodaltons; and "PES" means polyethersulfone.

[0118] Method for determining anomeric bonds using NMR spectroscopy The glycosidic bonds in water-soluble oligosaccharides and polysaccharide products synthesized by glucosyltransferase GTF8117 and α-1,2 branched enzymes are broken down. 1 The composition was determined by 1H NMR (nuclear magnetic resonance spectroscopy). A dried oligosaccharide / polysaccharide polymer (6-8 mg) was dissolved in 0.7 mL of 1 mM DSS (4,4-dimethyl-4-silapentane-1-sulfonic acid; NMR reference standard) solution in D2O. The sample was stirred overnight at ambient temperature. 525 μL of a clear homogeneous solution was transferred to a 5 mm NMR tube. 2D 1 H, 13 AGU (anhydrous glucose unit) bonds were identified using 1C homo / heterokeratogenic NMR experiments. Data were collected at 20°C and processed on a Bruker Advance III NMR spectrometer operating at either 500 MHz or 600 MHz. This system features a proton-optimized, helium-cooled cryogenic probe. 1D 1 The distribution of glycosidic bonds was quantified using 1H NMR spectroscopy, confirming that the polysaccharide backbone is primarily α-1,6. This result reflects the ratio obtained by dividing the integrated intensity of the NMR resonance representing each bond type by the total integrated intensity of all peaks representing glucose bonds, and multiplying by 100.

[0119] Method for evaluating the whiteness performance of polymers Whiteness retention, also known as whiteness retention, is the ability of a detergent to prevent the loss of whiteness in white items when washed in the presence of dirt. White clothing loses whiteness with each wash because it can appear dirty / dull over time as dirt is removed from the soiled clothing, suspended in the wash water, and then these dirt can reattach to the clothing. The whiteness effect of the currently disclosed polymers will be evaluated using an automatic mini washer with five pots. SBL2004 test dirt strips supplied by WFKTestgewebe GmbH will be used to simulate consumer dirt levels (a mixture of body dirt, food, grime, grass, etc.). On average, 8g of dirt will be loaded onto each SBL2004 strip. The white fabric samples in Table 2 below, purchased from WFK, will be used as whiteness tracers. Before the wash test, the L, a, and B values ​​of all whiteness tracers will be measured using a Konica Minolta CM-3610D spectrophotometer.

[0120] [Table 5] Note: * WI(A)-Light source A (indoor lighting) ** WI(D65)-Light source D65 (outdoor lighting)

[0121] Three cleaning cycles are required to complete the test. Cycle 1: Completely dissolve the desired amount of base detergent by mixing it with 7.57L of water (specified hardness) in the tube of each mini washer. Wash, rinse, and dry a 3.5 SBL2004 strip (approximately 28g of dirt) and three whiteness tracers (internal replicas) of each fabric type in the mini washer under specified conditions. Cycle 2: Wash the above whiteness tracer again using a new set of SBL2004 sheets and dry it. All other conditions remain the same as in Cycle 1. Cycle 3: Wash the above whiteness tracer again using a new set of SBL2004 sheets and dry it. All other conditions remain the same as in Cycle 1.

[0122] After cycle 3, all whiteness tracers are dried and then measured again using a Konica Minolta CM-3610 D spectrophotometer. Based on the L, a, and b measurements before and after washing, the change in the whiteness index (ΔWI(CIE)) is calculated. ΔWI(CIE) = WI(CIE) (after washing) - WI(CIE) (before washing).

[0123] The mini washer has five pots, allowing five products to be tested in a single test. Typically, in a polymer whiteness performance test, one reference product containing or without the comparative polymer is tested together with four products containing the polymer of the present invention, and the "ΔWI vs. reference" is reported. ΔWI(CIE) pair reference = ΔWI(CIE)(product) - ΔWI(CIE)(reference)

[0124] Methods for evaluating the cleaning effect of polymers: The cleaning effect of the polymer is evaluated using a turgotometer. Some examples of suitable test stains for this test are as follows: Standard glass, made by CFT. Standard clay, made by CFT. ASTM dust sebum, CFT made Highly discriminable sebum on polycotton, made with CFT. Burnt bacon on knitted cotton (made using Equest brand burnt bacon) Dyed bacon on knitted cotton (made using Equest brand dyed bacon).

[0125] Regarding the L, a, and b values, the fabric was analyzed using commercially available DigiEye software.

[0126] The polymer stock solution of the present invention was prepared in deionized water to a desired 5 mL. To prepare 1 L of test solution, 5 mL of the polymer stock solution and a desired amount of basic detergent were completely dissolved by mixing with water (defined hardness) in a turgotometer pot. The washing temperature was 20°C.

[0127] Each cloth washed in the Turgotometer pot contains two pieces of each test stain (two internal replicas), approximately 3g of WFK SBL2004 stain sheet, and additional knitted cotton ballast to bring the total cloth weight up to 60g.

[0128] Once all the fabrics were placed in a turgotometer pot containing the cleaning solution, the solution was agitated for 12 minutes. The cleaning solution was then drained, and the fabrics were subjected to two 5-minute rinse steps, after which they were drained and rotated dry. The cleaned stains were dried in an air-flow cabinet, and then the L, a, and b values ​​were analyzed using commercially available DigiEye software.

[0129] This procedure was repeated three more times to obtain 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. A higher SRI indicates better 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 ) The subscript "b" indicates the data of the stain before washing. The subscript "a" indicates the data of the stain after washing. The subscript "c" indicates the data of the stain-free cloth.

[0131] Polymer 1 of the present invention: Modification of poly α-1,3 glucan with benzoyl chloride in dimethylacetamide 550 g of dimethylacetamide, 37 g of poly α-1,3 glucan polymer (skeletal MW: 120K), and 26 g of calcium chloride dihydrate were added to a 1-liter resin kettle equipped with stirring and a jacket. After maintaining the contents at 70 °C for 2.25 hours, the poly α-1,3 glucan and calcium chloride dihydrate were dissolved in the solution. After heating the contents to 78 °C, 21 mL of benzoyl chloride was supplied over 1.5 minutes. The solution was maintained at 80 - 84 °C for 2 hours. Then, the heating of the reactor was stopped, vacuum pumping was performed to promote the evaporation cooling of the contents of the reactor. After removing 65 g of DMAc overhead, the reactor pressure was returned to atmospheric pressure, 443 g of the reaction solution was poured into acetone to precipitate the solid, and then the solid was slurried twice with 1 liter of methanol, filtered, and dried overnight to obtain this. NMR analysis of the product showed that the degree of substitution of the benzoate content was 0.20 and the degree of substitution of the acetate content was 0.08.
