Technical Field

[0001] The present disclosure relates to a laundry detergent comprising a poly-α-1,3-glucan ester. Background Art

[0002] Laundry detergent compositions are required to remove a broad range of soils and provide a broad range of cleaning performance. For some laundry detergent compositions, providing soil removal performance is very important. More specifically, it is important to provide good soil removal performance for body soils such as sebum soils. Additionally, providing good whiteness performance, especially when cleaning polyester fabrics, is also important.

[0003] The present invention solves this problem by providing a detergent composition having good soil removal performance (especially for body soils such as sebum) and good whiteness performance (especially for polyester fabrics). This is important, for example, for laundry detergent compositions designed to clean sportswear. The present invention achieves this by providing a laundry detergent composition comprising a soil-removing surfactant and a specific poly-α-1,3-glucan compound.

[0004] There is also a need for such polysaccharide derivatives to be readily biodegradable. The polymers of the present invention also exhibit good biodegradation performance.

[0035] Definition

[0036] As used herein, the article "a" refers to one and more than one, and does not necessarily limit the noun it refers to to the singular grammatical category.

[0037] As used herein, the terms "about" and "is or about" when used to modify a quantity or value refer to an approximation of the quantity or value that is greater than or less than the exact quantity or value recited in the claim or described herein. The exact value of the approximation is determined by a person of ordinary skill in the art to be an appropriate approximation of the exact value. As used herein, the term conveys that a similar value not precisely recited in the claim or described herein can produce the same result or effect as those values recited in the claim or described herein, for which a person of ordinary skill in the art will recognize that the similar value is acceptably obtained.

[0038] The terms "percent by volume", "volume percent", "volume %", and "volume / volume %" are used interchangeably herein. The volume percent of a solute in a solution can be determined using the following formula: [(volume of solute) / (volume of solution)] × 100%.

[0039] The terms "weight percent", "weight percentage (wt%)", and "weight-weight percentage (% wt / wt)" are used interchangeably herein. Weight percent refers to the percentage by mass of a material when it is included in a composition, mixture, or solution.

[0040] As used herein, "weight average molecular weight" or "Mw" is calculated as Mw = ΣNiMi 2 / ΣNiMi; where Mi is the molecular weight of the chain and Ni is the number of chains of that molecular weight. The 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.

[0041] 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 calculated as Mn = ΣNiMi / ΣNi, where Mi is the molecular weight of the chain and Ni 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, viscometry via the (Mark-Houwink equation), and colligative methods such as vapor pressure osmometry, end group determination, or proton NMR.

[0042] The terms "increased", "enhanced", and "improved" are used interchangeably herein. These terms can refer to, for example, 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%) more than an amount or activity being compared to.

[0043] The terms "poly-α-1,3-glucan", "α-1,3-glucan polymer", and "glucan polymer" are used interchangeably herein. Poly-α-1,3-glucan is a polymer comprising glucose monomer units linked together by glycosidic bonds, where at least about 50% of the glycosidic bonds are α-1,3-glycosidic bonds. Poly-α-1,3-glucan is a class of polysaccharide. The structure of poly-α-1,3-glucan can be shown as follows:

[0044]

[0045] Poly-α-1,3-glucan that can be used to prepare the poly-α-1,3-glucan ester compounds described herein can be prepared using chemical methods. Alternatively, it can be prepared by extracting it from various organisms such as fungi that produce poly-α-1,3-glucan. Alternatively, poly-α-1,3-glucan can be produced enzymatically from sucrose using one or more glucosyltransferases (gtf) (e.g., gtfJ), as described in U.S. Patent 7,000,000 and U.S. Patents 9,080,195 and 8,642,757 (all three patents are incorporated herein by reference).

[0046] The terms "glucosyltransferase", "gtf enzyme", "gtf enzyme catalyst", "gtf", and "dextransucrase" are used interchangeably herein. The gtf enzymes herein catalytically active react sucrose substrates to prepare the products poly-α-1,3-glucan and fructose. Other products (by-products) of the gtf reaction can include glucose (wherein glucose is hydrolyzed from the glucosyl-gtf enzyme intermediate complex), various soluble oligosaccharides (DP2-DP7), and levanbiose (wherein the glucose of the glucosyl-gtf enzyme intermediate complex is linked to fructose). Levanbiose is a disaccharide composed of glucose and fructose linked by an α-1,5 bond. The wild-type form of glucosyltransferase generally contains (in the direction from the N-terminus to the C-terminus) a signal peptide, a variable domain, a catalytic domain, and a glucan-binding domain. The gtf herein is classified under glycoside hydrolase family 70 (GH70) according to the CAZy (Carbohydrate-Active Enzymes) database (Cantarel et al., Nucleic Acids Res. 37:D233-238, 2009).

[0047] The percentage of α-1,3 glycosidic bonds between the glucose monomer units of the poly-α-1,3-glucan for preparing the poly-α-1,3-glucan ester compound described herein 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-α-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 non-α-1,3 glycosidic bonds.

[0048] The poly-α-1,3-glucan for preparing the poly-α-1,3-glucan ester compound described herein is preferably linear / non-branched. In certain embodiments, the poly-α-1,3-glucan does not have branch points or has branch points less than about 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% in terms of the percentage of glycosidic bonds in the polymer. Examples of branch points include α-1,6 branch points, such as those present in mutan polymers.

[0049] The terms "glycosidic linkage" and "glycosidic bond" are used interchangeably herein and refer to the type of covalent bond that links a carbohydrate (sugar) molecule to another group such as another carbohydrate. As used herein, the term "α-1,3-glycosidic bond" refers to the type of covalent bond that links α-D-glucose molecules to each other through carbons 1 and 3 on adjacent α-D-glucose rings. This bond is shown in the poly-α-1,3-glucan structure provided above. In this document, "α-D-glucose" is referred to as "glucose".

[0050] The terms "poly-α-1,3-glucan ester compound", "poly-α-1,3-glucan ester", and "poly-α-1,3-glucan ester derivative" are used interchangeably herein. The poly-α-1,3-glucan compound is represented by the following structure:

[0139] (e) containing -CO-C x -COOR 3 of the acyl group, wherein the -C x - part of the second acyl group contains a chain of 2 to 24 carbon atoms, and R 3 contains a chain of 1 to 24 carbons,

[0140] provided that if (a) is present, then at least one other ester group (b), (c), (d) and / or (e) is present, and

[0141] wherein the degree of substitution of the ester group modifier is from 0.001 to 3.

[0142] It may be preferred that the ester group modifiers are independently selected from:

[0143] (a) acetyl;

[0144] (b) aryl ester group;

[0145] (c) acyl group wherein a is independently 6 - 24; and

[0146] (d) any combination thereof.

[0147] It may be preferred that the ester group modifier is a combination of the following:

[0148] (a) acetyl;

[0149] (b) aryl ester group; and

[0150] (c) acyl group wherein a is independently 6 - 24.

[0151] It may be preferred that the ester group modifier of the poly-α-1,3-glucan ester compound is a combination of the following:

[0152] (a) acetyl; and

[0153] (b) aryl ester group.

[0154] It may be preferred that the ester group modifier of the poly-α-1,3-glucan ester compound is a combination of the following:

[0155] (a) acetyl; and

[0156] (b) benzoyl.

[0157] The degree of substitution of the ester group modifier of the poly-α-1,3-glucan ester compound is from 0.001 to 3, preferably from 0.005 to 2, more preferably from 0.01 to 1, and most preferably from 0.02 to 0.8.

[0158] Preferably, a is independently 9 - 16.

[0159] The poly-α-1,3-glucan derivatives disclosed herein comprise a backbone of poly-α-1,3-glucan that is randomly substituted along the polysaccharide backbone by ester modifiers such that the polysaccharide backbone generally comprises unsubstituted and substituted α-D-glucose rings. In embodiments where there are branches, the α-D-glucose rings of the branches may also be randomly substituted by ester modifier groups. As used herein, the term "randomly substituted" means that the substituents on the glucose rings in the randomly substituted polysaccharide occur in a non-repeating or random manner. That is, the substitution on a substituted glucose ring may be the same or different from the substitution on a second substituted glucose ring in the polysaccharide [i.e., substituents on different atoms of the glucose rings in the polysaccharide (which may be the same or different)], such that the overall substitution on the polymer is not regular. Additionally, the substituted glucose rings occur randomly within the polysaccharide (i.e., there is no pattern of substituted and unsubstituted glucose rings within the polysaccharide).

[0160] Depending on the reaction conditions, the poly-α-1,3-glucan ester compounds disclosed herein may also comprise a backbone of poly-α-1,3-glucan that is "non-randomly" substituted along the polysaccharide backbone by ester modifier groups. In the presence of branches, the α-D-glucose rings of the branches may disproportionately contain more substitutions than the main chain glucose monomer units linked by α-1,3-glycosidic bonds. It is also possible that, under certain reaction conditions, the modifiers may be present in the polysaccharide in a block manner.

[0161] Depending on the reaction conditions, it is also possible that the glucose carbon positions 1, 2, 3, 4, and 6 of the poly-α-1,3-glucan backbone are "disproportionately" substituted. For example, the -OH group at carbon position 6 is a primary hydroxyl group and may be in an environment with less steric hindrance. This OH group may have higher reactivity under certain reaction conditions, and thus, more substitutions may occur at this position. Under other reaction conditions, the OH groups at carbon positions 1, 2, 3, or 4 may have higher reactivity.

[0162] Without being bound by theory, it is believed that the cases of "disproportionately" and "non-randomly" substituted may have a higher chance when the degree of substitution is reduced.

Non-limiting examples of suitable enzymes include protease, cellulase, hemicellulase, peroxidase, lipolytic enzyme (e.g., metallolipolytic enzyme), xylanase, lipase, phospholipase, esterase (e.g., arylesterase, polyesterase), perhydrolase, cutinase, pectinase, pectate lyase, mannanase, keratinase, reductase, oxidase (e.g., choline oxidase), phenol oxidase, lipoxygenase, ligninase, pullulanase, tannase, pentosanase, malanases, β-glucanase, arabinosidase, hyaluronidase, chondroitinase, laccase, metalloprotease, amadoriase, glucoamylase, arabinofuranosidase, phytase, isomerase, transferase, amylase, or a combination thereof. If one or more enzymes are included, they may be present in the product at about 0.0001 wt% to 0.1 wt% active enzyme, based on the total weight of the composition. In other embodiments, the enzyme may be present at about 0.01 wt% to 0.03 wt% active enzyme (e.g., calculated as pure enzyme protein), 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 the following: 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, malanases, β-glucanase, arabinosidase, hyaluronidase, chondroitinase, laccase, metalloprotease, amadoriase, glucoamylase, arabinofuranosidase, phytase, isomerase, transferase, amylase, or a combination thereof.

[0166] In some embodiments, the composition can comprise one or more enzymes, each enzyme being present at about 0.00001 wt% to about 10 wt% based on the total weight of the composition. In some embodiments, the composition can further comprise each enzyme at a level of about 0.0001 wt% to about 10 wt%, about 0.001 wt% to about 5 wt%, about 0.001 wt% to about 2 wt%, or about 0.005 wt% to about 0.5 wt% based on the total weight of the composition.

[0167] The cellulase can have endoglucanase activity (EC 3.2.1.4), exoglucanase activity (EC 3.2.1.91), or cellobiase activity (EC 3.2.1.21). The cellulase is an "active cellulase" that is active under conditions suitable for maintaining cellulase activity; determining such suitable conditions is within the skill in the art. In addition to being able to degrade cellulose, the cellulase can also degrade cellulose ether derivatives, such as carboxymethyl cellulose, in certain embodiments.

[0168] The cellulase can be derived from any microbial source, such as bacteria or fungi. Chemically modified cellulases or protein-engineered mutant cellulases are included. Suitable cellulases include, for example, cellulases from the genus Bacillus, Pseudomonas, Streptomyces, Trichoderma, Humicola, Fusarium, Thielavia, and Acremonium. As other examples, the cellulase can be derived from Humicola insolens, Myceliophthora thermophile, Fusarium oxysporum, Trichoderma reesei, or combinations thereof. The cellulase, such as any of the foregoing, can be in a mature form lacking an N-terminal signal peptide. Commercially available cellulases that can be used herein include and (Novozymes A / S); and HA and REVITALENZ TM (DuPont Industrial Biosciences), (AB Enzymes); and (Kao Corporation).

[0169] Alternatively, the cellulases herein can be produced by any means known in the art. For example, cellulases can be recombinantly produced in a heterologous expression system such as a microbial or fungal heterologous expression system. Examples of heterologous expression systems include bacteria (e.g., Escherichia coli (E. coli), Bacillus spp.) and eukaryotic systems. Eukaryotic systems can employ, for example, yeast (e.g., Pichia spp., Saccharomyces spp.) or fungi (e.g., Trichoderma spp. such as Trichoderma reesei (T. reesei), Aspergillus spp. such as Aspergillus niger (A. niger)) expression systems.

[0170] In certain embodiments, the cellulase can be thermostable. Thermostability of a cellulase refers to the ability of the enzyme to retain activity after exposure to elevated temperatures (e.g., about 60 °C - 70 °C) for a period of time (e.g., about 30 minutes - 60 minutes). The thermostability of a cellulase can 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.

[0171] In certain embodiments, the cellulase can be stable over a wide pH range (e.g., neutral or alkaline pH, such as a pH of about 7.0 to about 11.0). Under such pH conditions, such enzymes can remain stable for a predetermined period of time (e.g., at least about 15 minutes, 30 minutes, or 1 hour).

[0172] At least one, two or more cellulases may be included in the composition. The total amount of cellulase in the compositions herein is generally an amount suitable for the purpose of using cellulase in the composition ("effective amount"). For example, the effective amount of cellulase in a composition intended to improve the feel and / or appearance of a cellulosic fabric is an amount that produces a measurable improvement in the feel of the fabric (e.g., improving fabric smoothness and / or appearance, removing fiber fuzz and fibrils that tend to reduce the sharpness of the fabric appearance). As another example, the effective amount of cellulase in a fabric stonewashing composition herein is an amount that will provide the desired effect (e.g., producing a worn and faded appearance in seams and on the fabric panel). The amount of cellulase in the compositions herein may also depend on, for example, process parameters in which the composition is employed (e.g., equipment, temperature, time, etc.) and cellulase activity. The effective concentration of cellulase in an aqueous composition for treating a fabric can be readily determined by one skilled in the art. In a fabric care process, cellulase can be present in an aqueous composition (e.g., a wash liquor) for treating a fabric at a concentration of, for example, at least about 0.01 ppm - 0.1 ppm total cellulase protein, or about 0.1 ppb - 10 ppb total cellulase protein (e.g., less than 1 ppm) up to a maximum of about 100 ppm, 200 ppm, 500 ppm, 1000 ppm, 2000 ppm, 3000 ppm, 4000 ppm, or 5000 ppm total cellulase protein.

[0182] The composition may further comprise silicates. Suitable silicates may include, for example, sodium silicate, disodium silicate, sodium metasilicate, crystalline layered silicates, or combinations thereof. In some embodiments, the silicate may be present in an amount of from about 1 wt% to about 20 wt%, based on the total weight of the composition.

[0183] The composition may further comprise a dispersant. Suitable water-soluble organic materials may include, for example, homopolyacids or copolyacids or their salts, wherein the polycarboxylic acid contains at least two carboxyl groups that are no more than two carbon atoms apart from each other.

[0264] Method for determining anomeric linkages by NMR spectroscopy

[0265] By 1 1H NMR (nuclear magnetic resonance spectroscopy) was used to determine the glycosidic linkages in water-soluble oligosaccharide and polysaccharide products synthesized from glucosyltransferase GTF8117 and α-1,2 branching enzyme. The dried oligosaccharide / polysaccharide polymer (6 mg to 8 mg) was dissolved in 0.7 mL of a D2O solution of 1 mM DSS (4,4-dimethyl-4-silapentane-1-sulfonic acid; NMR reference standard). The sample was stirred overnight at ambient temperature. 525 uL of the clear homogeneous solution was transferred to a 5 mm NMR tube. The 2D 1 1H, 13The C homo- / hetero-nuclear suite software is used to identify AGU (anhydroglucose unit) linkages. Data is collected at 20 °C and processed on a Bruker Avance III NMR spectrometer operating at 500 MHz or 600 MHz. The system is equipped with a proton-optimized helium-cooled cryoprobe. 1D 1 H NMR spectra are used to quantify the glycosidic bond distribution and to find the polysaccharide backbone, such as predominantly α-1,6. The results are reflected as the ratio of the integrated intensity of the NMR resonances representing each bond type divided by the integrated intensity of all the peaks representing glucose linkages, multiplied by 100.

[0266] Method for evaluating whiteness properties of polymers

[0267] Whiteness retention (also known as whiteness maintenance) is the ability of a detergent to prevent loss of whiteness of white articles during washing in the presence of soil. When soil is removed from a dirty fabric and suspended in the wash water, this soil may redeposit onto the clothes, making the clothes less white with each wash and causing white clothes to appear dirty over time. The whiteness benefits of the presently disclosed polymers are evaluated using an automatic small washing machine with 5 cylinders. SBL2004 test soil bars supplied by WFK Testgewebe GmbH are used to simulate consumer soil levels (a mixture of body soil, food, dust, grass, etc.). On average, each SBL2004 bar is loaded with 8 g of soil. White fabric samples from Table 2 purchased from WFK are used as whiteness tracers. Before the wash tests, the L, a, b values of all whiteness tracers are measured using a Konica Minolta CM-3610D spectrophotometer.

[0272] *WI(A) – Light source A (indoor lighting)

[0273] **WI(D65) – Light source D65 (outdoor lighting)

[0274] Three wash cycles are required to complete the test:

[0275] Cycle 1: Dissolve the required amount of the base detergent completely by mixing it with 7.57 L of water (at defined hardness) in each small washing machine tube. Under defined conditions, wash, rinse, and then dry 3.5 SBL2004 strips (about 28 g of soil) and 3 whiteness tracers of each fabric type (internal parallel determination) in the small washing machine.

[0276] Cycle 2: Wash the above whiteness tracers again with a new set of SBL2004 tablets and dry. All other conditions remain the same as in Cycle 1.

[0277] Cycle 3: Wash the above whiteness tracers again with a new set of SBL2004 tablets and dry. All other conditions remain the same as in Cycle 1.

[0278] After Cycle 3, dry all the whiteness tracers and then measure them again using a Konica Minolta CM-3610D spectrophotometer. Based on the L, a, b measurements before and after washing, calculate the change in whiteness index (ΔWI(CIE)).

[0279] ΔWI(CIE) = WI(CIE) (after washing) – WI(CIE) (before washing).

[0280] The small washing machine has 5 tanks and can test 5 products in one test. In a typical polymer whiteness performance test, one reference product containing a comparative polymer or no polymer is tested together with 4 products containing the polymer of the present invention, and "ΔWI relative to the reference" is reported.

[0281] ΔWI(CIE) relative to the reference = ΔWI(CIE) (product) - ΔWI(CIE) (reference)

[0282] Method for evaluating cleaning beneficial effects of polymers

[0283] Use a stir-type detergency washing machine to evaluate the cleaning beneficial effects of the polymer. Some examples of test soils suitable for this test are:

[0284] Standard grass, ex CFT

[0285] Standard clay, ex CFT

[0286] ASTM dust sebum, ex CFT

[0287] Highly distinguishable sebum on polyester cotton, ex CFT

[0288] Barbecue bacon on knitted cotton (prepared using barbecue bacon from ex Equest)

[0289] Dyed bacon on knitted cotton (prepared using the dyed bacon of ex Equest)

[0290] Commercially available DigiEye software was used to analyze the L, a, b values of the fabric.

[0291] The polymer stock solution of the present invention was prepared in deionized water to deliver the required dose via 5 ml aliquots. To prepare 1 L of the test solution, 5 ml aliquots of the polymer stock solution and the required amount of alkaline detergent were completely dissolved by mixing in the drum of a stir-type washing power washing machine with water (at a defined hardness). The washing temperature was 20 °C.

[0292] The fabric to be washed in the drum of each stir-type washing power washing machine included 2 test stains each (2 internal parallel determinations), approximately 3 g of WfK SBL 2004 soil chips, and additional knitted cotton ballast to bring the total fabric weight to 60 g.

[0293] Once all the fabric was added to the drum of the stir-type washing power washing machine containing the washing solution, the washing solution was stirred for 12 minutes. Then the washing solution was drained, and the fabric was rinsed twice for 5 minutes, then drained and spin-dried. The washed stains were dried in a fume hood and then the L, a, b values were analyzed using commercially available DigiEye software.

[0294] The process was repeated three more times to obtain a total of four external parallel determinations.

[0295] The soil removal index (SRI) was calculated from the L, a, b values using the formula shown below. The higher the SRI, the better the soil removal effect.

[0296] SRI = 100 * ((ΔE b – ΔE a ) / ΔE b ))

[0297] ΔE b = √((L c -L b ) 2 +(a c -a b ) 2 +(b c -b b ) 2 )

[0298] ΔE a = √((L c -L a ) 2 +(a c -a a ) 2+(b c -b a ) 2 )

[0299] The subscript 'b' represents the data of the stain before washing

[0300] The subscript 'a' represents the data of the stain after washing

[0301] The subscript 'c' represents the data of the undyed fabric

[0302] Polymer 1 of the present invention :

[0303] Modification of poly-α-1,3-glucan with benzoyl chloride in dimethylacetamide

[0304] 550 g of dimethylacetamide, 37 g of poly-α-1,3-glucan polymer (main chain 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 ℃ for a period of 2.25 hours, poly-α-1,3-glucan and calcium chloride dihydrate were added to the solution. The contents were heated to 78 ℃ and then 21 ml of benzoyl chloride was fed in over a period of 1.5 minutes. The solution was maintained between 80 ℃ and 84 ℃ for 2 hours. Then the heating of the reactor was turned off and the reactor was evacuated to promote evaporative cooling of the reactor contents. After removing 65 g of the DMAc overhead distillate, the reactor pressure was raised back to atmospheric pressure and 443 g of the reactor liquid was poured into acetone to precipitate the solid, and then the solid was slurried twice with 1 liter of methanol, filtered, and dried overnight. NMR analysis of the product indicated a benzoate content of 0.20 and an acetate content of 0.08 in terms of degree of substitution.

[0326] Biodegradation data

[0327] Biodegradation test method

[0328] The biodegradability of the polysaccharide derivative was determined according to the OECD 301B Ready Biodegradability CO2 Evolution Test Guideline. In this study, the test substance was the sole carbon and energy source, and under aerobic conditions, microorganisms metabolized the test substance, resulting in the production of CO2 or the incorporation of carbon into biomass. The amount of CO2 produced by the test substance (corrected for the CO2 emitted by the blank inoculum) was expressed as a percentage of the theoretical amount of CO2 (ThCO2) that could be produced if the organic carbon in the test substance was completely converted to CO2.
