  • Combinations of hydrophobic monomers can also be used.
  • the polymerization process can be a solution or suspension process.
  • the process involves polymerization using free radical initiators with one or more of the above hydrophilic and/or hydrophobic monomers, and the hydroxyl containing natural products used as chain transfer agents or chain stoppers. These chain transfer agents can be added either at the beginning of the reaction or during reaction as the monomer(s) is (are) added.
  • One advantage of this system is that it makes use of typical free radical initiators. Unlike grafting systems, special redox systems such as Ce(IV) salts are not required. Instead, easy-to-use thermally activated initiators such as sodium persulfate can be used. One skilled in the art will recognize that most initiating systems are applicable here.
  • a high degree of chain transfer can lead to crosslinking and formation of an insoluble gel. In one embodiment, this can be avoided by ensuring that monomer and initiator are fed over the same approximate period of time. If initiator feed lasts much longer than monomer feed, a crosslinked gel can form, particularly when oligopolysaccharides and polysaccharides (those having a molecular weight greater than about 1000) are used as the chain transfer agent.
  • the reaction product forms a hybrid gel during manufacture of these starch polycarboxylates.
  • the synthetic monomer used is extremely reactive (e.g., acrylic acid reacted at low pH (protonated form)) or if the natural chain transfer agent has a molecular weight of greater than about 1000.
  • a crosslinked gel starts to form after the monomer feed has ended and while the rest of the initiator is being fed in. This is undesirable in most cases, since the gel product cannot be diluted in water and therefore cannot be used in the applications described below.
  • the exception to this is in the manufacture of super absorbents, rheology modifiers and gels used to treat wells in the oil field industry.
  • an undesirable gel starts to form during the process due to a reactive monomer, it can be eliminated in a number of ways. This includes reducing monomer reactivity by neutralizing the monomer. Sodium acrylate is far less reactive than acrylic acid and therefore does not form gels that acrylic acid may form. In another embodiment, additional chain transfer agents like thiols, sodium hypophosphite and alcohols can also be used. Thiols and alcohols are particularly useful in controlling molecular weight and preventing the formation of crosslinked gels. Finally, these gels can be eliminated by shortening the initiator feeds so that the initiator and monomer feeds are pumped over the same period of time.
  • Stabilization of aqueous systems that include scale-forming salts and inorganic particulates involves a variety of mechanisms. Inhibition is one conventional mechanism for eliminating the deleterious effect of scale-forming salts. In inhibition, synthetic polymer(s) are added that increase the solubility of the scale-forming salt in the aqueous system. [0060] Another stabilization mechanism is the dispersion of precipitated salt crystals. Synthetic polymers having carboxylic acid groups function as good dispersants for precipitated salts such as calcium carbonates. In this mechanism, the crystals stay dispersed rather than dissolving in the aqueous solution.
  • a third stabilization mechanism involves interference and distortion of the crystal structure of the scale by the polymer, thereby making the scale less adherent to surfaces, other forming crystals and/or existing particulates.
  • the number average molecular weight of the starch polycarboxylate is between about 1000 and about 100,000. In another aspect, the number average molecular weight of the polymer is between about 2000 and about 25,000. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
  • the biopolymer includes a cellulose or a substituted cellulose.

CLEANING COMPOSITION
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No. 63/383,324, filed November 11, 2022, which is expressly incorporated herein by reference in its entirety.
TECHNICAL FIELD
[0002] The present disclosure generally relates to cleaning compositions that include a chelating agent and a biopolymer. More specifically, this disclosure relates to cleaning compositions that include low phosphorous contents.
BACKGROUND
[0003] Phosphonates are a class of compounds often used in consumer goods for various purposes, including as chelating agents in detergents and cleaning products, as scale inhibitors in water treatment, and as corrosion inhibitors in various industrial applications. The functionality of phosphonates is generally threefold. First, phosphonates function to chelate (transition) metal ions. Second, phosphonates act as crystal growth inhibitors. Third, phosphonates act as anti-redeposition aids.
[0004] Phosphonates tend to be used in low quantities in many formulations. They tend to have desirable cost efficiency and tend to be stable such that phosphonates are a part of the toolbox of formulators in the art.
[0005] While phosphonates have proven effective for these purposes, there are several reasons why it is important to consider replacing them in consumer goods. Phosphonates can persist in the environment and may not easily biodegrade. When they enter water bodies, they can contribute to algal blooms and oxygen depletion. Because of these drawbacks, many governments are regulating phosphonates.
[0006] Accordingly, there remains an opportunity to develop sustainable products including eco- friendly alternatives to phosphonates. Furthermore, other desirable features and characteristics of the present disclosure will become apparent from the subsequent detailed description of the disclosure and the appended claims, taken in conjunction with the accompanying drawings and this background of the disclosure. BRIEF SUMMARY

A. a chelating agent present in an amount of from about 0.1 to about 25 weight percent actives based on a total weight of the cleaning composition;
B. a biopolymer chosen from starch polycarboxylates, carboxymethyl celluloses, and combinations thereof and present in an amount of from about 0.1 to about 15 weight percent actives based on a total weight of the cleaning composition;
C. a surfactant present in an amount of from about 1 to about 30 weight percent actives based on a total weight of the cleaning composition;
D. an enzyme optionally present in an amount of from about 0.2 to about 4 weight percent actives based on a total weight of the cleaning composition; and
E. a phosphorous-containing compound; wherein the cleaning composition has a phosphorous content of less than about 1 weight percent actives based on a total weight of the cleaning composition.

In various nonlimiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
Starch Polycarboxylate
[0046] The starch polycarboxylates can be produced by using hydroxyl-containing naturally derived materials as chain transfer agents during production. The hydroxyl containing naturally derived materials range from small molecules such as glycerol, citric acid, lactic acid, tartaric acid, gluconic acid, glucoheptonic acid, monosaccharides and disaccharides such as sugars, to larger molecules such as oligosaccharides and polysaccharides (e.g., maltodextrins and starches). Examples of these include sucrose, fructose, maltose, glucose, and saccharose, as well as reaction products of saccharides such as mannitol, sorbitol and so forth. The chain transfer agents include oxidatively, hydrolytically or enzymatically degraded monosaccharides, oligosaccharides and polysaccharides, as well as chemically modified monosaccharides, oligosaccharides and polysaccharides. Such chemically modified derivatives include carboxylates, sulfonates, phosphates, phosphonates, aldehydes, silanes, alkyl glycosides, alkyl-hydroxy alkyls, carboxyalkyl ethers and other derivatives. [0047] Polysaccharides useful herein can be derived from plant, animal and microbial sources. Examples of such polysaccharides include starch, cellulose, gums (e.g., gum arabic, guar and xanthan), alginates, pectin and gellan. Starches include those derived from maize and conventional hybrids of maize, such as waxy maize and high amylose (greater than 40% amylose) maize, as well as other starches such as potato, tapioca, wheat, rice, pea, sago, oat, barley, rye, and amaranth, including conventional hybrids or genetically engineered materials.
[0048] Also included are hemicellulose or plant cell wall polysaccharides such as D-xylans. Examples of plant cell wall polysaccharides include arabino-xylans such as corn fiber gum, a component of corn fiber. The hydroxyl groups of the polysaccharides provide sites for chain transfer during the polymerization process. The higher the number of secondary and tertiary hydroxyl groups in the molecule the more effective it will be as chain transfer agent.
[0049] Other polysaccharides useful as chain transfer agents include maltodextrins, which are polymers having D-glucose units linked primarily by a- 1,4 bonds and have a dextrose equivalent (‘DE’) of less than about 20. Maltodextrins are available as a white powder or concentrated solution and are prepared by the partial hydrolysis of starch with acid and/or enzymes. In one aspect, the chain transfer agents are glycerol, citric acid, maltodextrins and/or low molecular weight oxidized starches. Useful chain transfer agents have molecular weights of less than about 20,000. In another aspect, the chain transfer agents have molecular weights of less than about 2000. In even another aspect, chain transfer agents a have molecular weights of less than 1000. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0050] Polysaccharides can be modified or derivatized by etherification (e.g., via treatment with propylene oxide, ethylene oxide, 2,3-epoxypropyltrimethylammonium chloride), esterification (e.g., via reaction with acetic anhydride, octenyl succinic anhydride (‘OSA’)), acid hydrolysis, dextrinization, oxidation or enzyme treatment (e.g., starch modified with a-amylase, 0-amylase, pullanase, isoamylase or glucoamylase), or various combinations of these treatments.
[0051] The hydroxyl-containing naturally derived chain transfer agents can be used in amounts of from about 0.1 to about 75 weight % based on total weight of the polymer. In one aspect, the range is from about 1 to about 50 weight % of chain transfer agents based on total weight of the polymer. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0052] In one embodiment, the starch polycarboxylates are prepared from at least one hydrophilic acid monomer as the synthetic constituent. Examples of such hydrophilic acid monomers include but are not limited to acrylic acid, methacrylic acid, ethacrylic acid, a-chloro- acrylic acid, a-cyano acrylic acid, 0-methyl-acrylic acid (crotonic acid), a-phenyl acrylic acid, 0- acryloxy propionic acid, sorbic acid, a-chloro sorbic acid, angelic acid, cinnamic acid, p-chloro cinnamic acid, 0-styryl acrylic acid (l-carboxy-4-phenyl butadiene- 1,3), itaconic acid, maleic acid, citraconic acid, mesaconic acid, glutaconic acid, aconitic acid, fumaric acid, tricarboxy ethylene, 2-acryloxypropionic acid, 2-acrylamido-2-methyl propane sulfonic acid, vinyl sulfonic acid, sodium methallyl sulfonate, sulfonated styrene, allyloxybenzene sulfonic acid and maleic acid. Moieties such as maleic anhydride or acrylamide that can be derivatized to an acid containing group can be used. Combinations of acid-containing hydrophilic monomers can also be used. In one aspect the acid-containing hydrophilic monomer is acrylic acid, maleic acid, methacrylic acid,
2-acrylamido-2-methyl propane sulfonic acid or mixtures thereof.
[0053] In addition to the hydrophilic monomers described above, hydrophobic monomers can also be used as a synthetic constituent. These hydrophobic monomers include, for example, ethylenically unsaturated monomers with saturated or unsaturated alkyl, hydroxyalkyl, alkylalkoxy groups, arylalkoxy, alkarylalkoxy, aryl and aryl-alkyl groups, alkyl sulfonate, aryl sulfonate, siloxane and combinations thereof. Examples of hydrophobic monomers include styrene, a-methyl styrene, methyl methacrylate, methyl acrylate, 2-ethylhexyl acrylate, octyl acrylate, lauryl acrylate, stearyl acrylate, behenyl acrylate, 2-ethylhexyl methacrylate, octyl methacrylate, lauryl methacrylate, stearyl methacrylate, behenyl methacrylate, 2-ethylhexyl acrylamide, octyl acrylamide, lauryl acrylamide, stearyl acrylamide, behenyl acrylamide, propyl acrylate, butyl acrylate, pentyl acrylate, hexyl acrylate, 1 -vinyl naphthalene, 2-vinyl naphthalene,
3-methyl styrene, 4-propyl styrene, t-butyl styrene, 4-cyclohexyl styrene, 4-dodecyl styrene, 2- ethyl-4-benzyl styrene, and 4-(phenyl butyl) styrene. Combinations of hydrophobic monomers can also be used.
[0054] The polymerization process can be a solution or suspension process. The process involves polymerization using free radical initiators with one or more of the above hydrophilic and/or hydrophobic monomers, and the hydroxyl containing natural products used as chain transfer agents or chain stoppers. These chain transfer agents can be added either at the beginning of the reaction or during reaction as the monomer(s) is (are) added.
[0055] One advantage of this system is that it makes use of typical free radical initiators. Unlike grafting systems, special redox systems such as Ce(IV) salts are not required. Instead, easy-to-use thermally activated initiators such as sodium persulfate can be used. One skilled in the art will recognize that most initiating systems are applicable here.
[0056] A high degree of chain transfer can lead to crosslinking and formation of an insoluble gel. In one embodiment, this can be avoided by ensuring that monomer and initiator are fed over the same approximate period of time. If initiator feed lasts much longer than monomer feed, a crosslinked gel can form, particularly when oligopolysaccharides and polysaccharides (those having a molecular weight greater than about 1000) are used as the chain transfer agent.
[0057] In some embodiments, the reaction product forms a hybrid gel during manufacture of these starch polycarboxylates. This is especially true if the synthetic monomer used is extremely reactive (e.g., acrylic acid reacted at low pH (protonated form)) or if the natural chain transfer agent has a molecular weight of greater than about 1000. A crosslinked gel starts to form after the monomer feed has ended and while the rest of the initiator is being fed in. This is undesirable in most cases, since the gel product cannot be diluted in water and therefore cannot be used in the applications described below. The exception to this is in the manufacture of super absorbents, rheology modifiers and gels used to treat wells in the oil field industry.
[0058] If an undesirable gel starts to form during the process due to a reactive monomer, it can be eliminated in a number of ways. This includes reducing monomer reactivity by neutralizing the monomer. Sodium acrylate is far less reactive than acrylic acid and therefore does not form gels that acrylic acid may form. In another embodiment, additional chain transfer agents like thiols, sodium hypophosphite and alcohols can also be used. Thiols and alcohols are particularly useful in controlling molecular weight and preventing the formation of crosslinked gels. Finally, these gels can be eliminated by shortening the initiator feeds so that the initiator and monomer feeds are pumped over the same period of time.
[0059] Stabilization of aqueous systems that include scale-forming salts and inorganic particulates involves a variety of mechanisms. Inhibition is one conventional mechanism for eliminating the deleterious effect of scale-forming salts. In inhibition, synthetic polymer(s) are added that increase the solubility of the scale-forming salt in the aqueous system. [0060] Another stabilization mechanism is the dispersion of precipitated salt crystals. Synthetic polymers having carboxylic acid groups function as good dispersants for precipitated salts such as calcium carbonates. In this mechanism, the crystals stay dispersed rather than dissolving in the aqueous solution.
[0061] A third stabilization mechanism involves interference and distortion of the crystal structure of the scale by the polymer, thereby making the scale less adherent to surfaces, other forming crystals and/or existing particulates.
[0062] In one aspect, the number average molecular weight of the starch polycarboxylate is between about 1000 and about 100,000. In another aspect, the number average molecular weight of the polymer is between about 2000 and about 25,000. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
Cellulose
[0063] In various embodiments, the biopolymer includes a cellulose or a substituted cellulose. As used herein, the term "celluloses" includes natural celluloses and synthetic celluloses. Celluloses can be extracted from plants or produced by microorganisms and sea creatures, like tunicates. The cellulose may be further defined as a substituted carboxymethyl cellulose.
[0064] In various embodiments, the substituted cellulose comprises a cellulose backbone consisting essentially of glucose units. The degree of substitution, DS, of the substituted cellulose is typically of from about 0.1 to about 1.5, e.g. about 0.2 to about 1.4, about 0.3 to about 1.3, about 0.4 to about 1.2, about 0.5 to about 1.1, about 0.6 to about 1, about 0.7 to about 0.9, or about 0.8 to about 0.9. The sum of the degree of substitution and the degree of blockiness, DS+DB, of the substituted cellulose may be of at least 1. The DB+2DS-DS2 of the substituted cellulose may be of at least 1.10. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0065] It is contemplated that the substituted cellulose may be substituted with identical or different substituents. In various embodiments, the substituted cellulose comprises unsubstituted glucose units. Unsubstituted glucose units are glucose units having all their hydroxyl groups remaining unsubstituted. In the substituted cellulose, the weight ratio of unsubstituted glucose units to the total number of glucose units may be from about 0.01 to about 0.99. In various non- limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0066] Typically, the substituted cellulose comprises substituted glucose units. Substituted glucose units are glucose units having at least one of their hydroxyl groups being substituted. In the substituted cellulose, the weight ratio of substituted glucose units to the total number of glucose units is typically of from about 0.01 to about 0.99. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0067] The cellulose has a backbone that is typically substantially linear. By substantially linear it is to be understood that at least about 97%, for example at least about 99% (by weight), or all the glucose units of the polymer are in the main chain of the cellulose backbone. In various nonlimiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0068] Celluloses have a substantially P-1,4 linked backbone. By substantially P-1,4 linked backbone it is to be understood that at least about 97%, for example at least about 99% (by weight), or all the glucose units of the polymer are bounded with P-1,4 linkage. When present, the remaining glucose units of the cellulose backbone may be bounded in a variety of ways, such as a- or P-and 1-2, 1-3, 1-4, 1-6 or 2-3 linkages and mixtures thereof. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0069] Typically, the cellulose backbone consists essentially of glucose units. Consisting essentially of glucose units should be understood as comprising more than about 95% or about 97%, for example more than about 99%, or even comprising about 100% by weight of glucose units. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0070] In various embodiments, the substituted cellulose comprises at least one glucose unit of its backbone which is carboxymethyl substituted. The substituent can be a carboxymethyl group.
[0071] In other embodiments, the substituted cellulose of the invention has a DS of about 0.01 to about 0.99. The skilled person appreciates that the term "degree of substitution" (or DS) refers to average degree of substitution of the functional groups on the cellulose units of the cellulose backbone. Thus, as each of the glucose unit of the cellulose backbone comprises three hydroxyl groups, the maximum degree of substitution of the substituted cellulose is 3. DS values do not generally relate to the uniformity of substitution of chemical groups along the cellulose backbone and are not related to the molecular weight of the cellulose backbone. The degree of substitution of the substituted cellulose is typically of at least about 0.02 or about 0.05, in particular of at least about 0.10 or about 0.20 or even about 0.30. Typically, the degree of substitution of the cellulose backbone is from about 0.50 to about 0.95, in particular from about 0.55 to about 0.90, or from about 0.60 to about 0.85, or even from about 0.70 to about 0.80. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0072] The methods to measure the DS may vary as a function of the substituent. The skilled person knows or may determine how to measure the degree of substitution of a given substituted cellulose. By way of example, a method to measure the DS of a carboxymethylcellulose is disclosed thereafter.
[0073] For example, DS can be determined by igniting CMC to ash at high temperature (650°C) for 45 minutes in order to remove all the organic material. The remaining inorganic ashes can then be dissolved in distilled water and methyl red added. The sample can then be titrated with 0.1M hydrochloric acid until the solution turned pink. The DS can be calculated from the amount of titrated acid (b ml) and the amount of CMC (G g) using the formula:
DS=0.162*0. l*b/G/l-(0.08*0. l*b/G.
[0074] Alternatively, the DS of a substituted cellulose may be measured by conductimetry or 13C NMR. Experimental protocols for both approaches are given in D. Capitani et al, Carbohydrate Polymers, 2000, v42, pp283-286, which is expressly incorporated herein by reference in various non-limiting embodiments.
[0075] In still other embodiments, the substituted cellulose can have a degree of blockiness (DB) such as either DB+DS is at least of about 1 or DB+2DS-DS2 is of at least about 1.20. The skilled person appreciates that term "degree of blockiness" (DB) refers to the extent to which substituted (or unsubstituted) glucose units are clustered on the cellulose backbone. Substituted celluloses having a lower DB may be described as having a more even distribution of the unsubstituted glucose units along the cellulose backbone. Substituted celluloses having a higher DB may be described as having more clustering of the unsubstituted glucose units along the cellulose backbone. More specifically, in a substituted cellulose comprising substituted and unsubstituted glucose units, the DB of the substituted cellulose is equal to B/(A+B), with A referring to the number of unsubstituted glucose units directly linked to at least one substituted glucose units, and B refers the number of unsubstituted glucose units not directly linked to a substituted glucose unit (i.e. only directly linked to unsubstituted glucose units).
[0076] In various embodiments, the substituted cellulose has a DB of at least about 0.35, or even from about 0.40 to about 0.90, from about 0.45 to about 0.80, or even from about 0.50 to about 0.70. The substituted cellulose may have a DB+DS of at least about 1. Typically the substituted cellulose has a DB+DS of from about 1.05 to about 2.00, or from about 1.10 to about 1.80, or from about 1.15 to about 1.60, or from about 1.20 to about 1.50, or even from about 1.25 to about 1.40. In other embodiments, the substituted cellulose has a DS of from about 0.01 to about 0.20 or about 0.80 to about 0.99 and/or may have a DB+DS of at least about 1, typically of from about 1.05 to about 2.00, or from about 1.10 to about 1.80, or from about 1.15 to about 1.60, or from about 1.20 to about 1.50, or even from about 1.25 to about 1.40. In other embodiments, the substituted cellulose has a DS of from about 0.20 to about 0.80 and may have a DB+DS of at least about 0.85, about 0.90 to about 1.80, or from about 1.00 to about 1.60, or from about 1.10 to about 1.50, or from about 1.20 to about 1.40. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0077] In further embodiments, the substituted cellulose may have a DB+2DS-DS2 of at least about 1.20. Typically the substituted cellulose has a DB+2DS-DS2 of from about 1.22 to about 2.00, or from about 1.24 to about 1.90, or from about 1.27 to about 1.80, or from about 1.30 to about 1.70, or even from about 1.35 to about 1.60. In other embodiments, the substituted cellulose has a DS comprised of from about 0.01 to about 0.20 and may have a DB+2DS-DS2 of from at least about 1.02 or from about 1.05 to about 1.20. In other embodiments, the substituted cellulose has a DS of from about 0.20 to about 0.40 and may have a DB+2DS-DS2 of from about 1.05 to about 1.10 or from about 1.10 to about 1.40. In other embodiments, the substituted cellulose has a DS of from about 0.40 to about 1.00, about 0.60 to about 1.00, or about 0.80 to about 1.00 and may have a DB+2DS-DS2 of from about 1.10 to about 2.00, or from about 1.20 to about 1.90, or from about 1.25 to about 1.80, or from about 1.20 to about 1.70, or even from about 1.35 to about 1.60. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[0078] The methods to measure the DB may vary as a function of the substituent. The skilled person knows or may determine how to measure the degree of blockiness of a given substituted cellulose. By way of example, a method to measure the DB of a substituted cellulose is disclosed herein. In the case of a substituted cellulose, the DB may correspond to the amount (A) of nonsubstituted glucose units released after a specific enzymatic hydrolysis with the commercial endoglucanase enzyme (Econase CE, AB Enzymes, Darmstadt, Germany) divided by the total amount of non-substituted glucose units released after acid hydrolysis (A+B). The enzymatic activity is specific to non-substituted glucose units in the polymer chain that are directly bounded to another non-substituted glucose unit. Further description of substituted cellulose blockiness and measurement is provided in detail in V. Stigsson et al., Cellulose, 2006, 13, pp705-712, which is expressly incorporated herein by reference in various non-limiting embodiments.
[0079] In various embodiments, enzymatic degradation is performed using the enzyme (Econase CE) in a buffer at pH 4.8 at 50°C for 3 days. To 25 ml of substituted cellulose sample, 250 pL of enzyme is used. The degradation is stopped by heating the samples to 90°C and keeping them hot for 15 minutes. The acid hydrolysis for both substitution pattern and blockiness is carried out in perchloric acid (15 min in 70% HCIO4 at room temperature and 3 hours in 6.4% HCIO4 at 120°C). The samples are analyzed using Anion Exchange Chromatography with Pulsed Amperiometric Detection (PAD detector: BioLC50 (Dionex, Sunnyvale, California, USA)). The HPAEC/PAD system is calibrated with C13 NMR. The monosaccharides are separated at 35°C using a flow rate of 0.2ml/min on a PA-1 analytical column using lOOmM NaOH as eluent with increasing sodium acetate (from 0 to IM sodium acetate in 30 mins). Each sample is analyzed three to five times and an average is calculated. The number of unsubstituted glucose that were directly linked to at least one substituted glucose (A), and the number of unsubstituted glucose that were not directly linked to a substituted glucose (B) are deduced and the DB of the substituted cellulose sample is calculated: DB = B/(A+B).
[0080] In further embodiments, the substituted cellulose has typically a viscosity at 25°C when dissolved at 2% by weight in water of at least about 100 mPa.s for example a viscosity of from about 250 to about 5000, or from about 500 to about 4000, from about 1000 to about 3000 or from about 1500 to about 2000 mPa.s. The viscosity of the cellulose may be measured according to the following test method.

This can enable stains occurring subsequent to treatment with the soil release agent to be more easily cleaned in later washing procedures.
[00136] Exemplary anti-redeposition agents include an acrylic polymer selected from Sokalan PA 30, Sokalan PA 20, Sokalan PA 15, and Sokalan CP 10 (BASF GmbH, Germany) and Acusol 445G and Acusol 445N (The Dow Chemical Company, Midland, Mich.); an acrylic acid/maleic acid copolymer selected from Acusol 460N and Acusol 505N (The Dow Chemical Company) and Sokalan CP 5, Sokalan CP 45, and Sokalan CP 7 (BASF GmbH, Germany); and an anionic polymer selected from Alcosperse 725 and Alcosperse 747 (Nouryon, Chattanooga, Tenn.) and Acusol 480N (The Dow Chemical Company, Midland, Mich.); and Dequest SPE 1202 (Italmatch Chemicals, Genova, Italy); and an ethoxylated polyethylene imine Sokalan HP 20 (BASF, Germany).
[00137] Suitable soil-releasing polymers include, but are not limited to, Texcare SRN — a nonionic polyester of polypropylene terephthalate (Clariant); REPEL-O-TEX SRP — a polyethylene glycol polyester (Solvay); end-capped and non-end-capped sulfonated and unsulfonated PET/POET polymers; polyethylene glycol/polyvinyl alcohol graft copolymers such as SOKALAN HP 22 (BASF, Germany); and anionic hydrophobic polysaccharides.
[00138] The composition may include a buffer. A wide range of buffers can be used herein. For example, the buffer may comprise a citrate or a formate, and optionally an amine (e.g., triethanolamine). In some embodiments, the liquid composition contains from about 1 to about 15 wt %, preferably from about 5 to about 10 wt % of the buffer, based on the total weight of the liquid composition.
Physical Properties
[00139] The composition is not limited to having any particular physical properties. In various embodiments, the composition has a Renewable Carbon Index (RCI) of at least 50, 55, 60, 65, 70, 75, 80, etc. % as of as determined using ISO 16128-2 2017 or DIN EN 16785-2. In various nonlimiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[00140] In other embodiments, the composition includes surfactants and/or chelating agents and/or biopolymers that may have a biodegradation in aerobic conditions of more than about 60, 65, 70, 75, 80, 85, 90, or even 95, % at 28 days as determined by OECD 301D or OECD 301B. These may be any described herein. Typically, inherent biodegradation is defined as degrading greater than about 20 percent to less than about 60 percent within 28 days. Readily biodegradable materials, on the other hand, degrade by about 60 percent or more within 28 days or less. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[00141] In other embodiments, the stain removal efficiency of the compositions is determined from the stain removal index (%SRI) on a scale 0% (unwashed) to 100% (complete stain removal) using a Minolta Spectrophotometer calibrated at D65/10+UV. The improvement is assessed by scaling the %SRI to reference (composition without varied component) and results reported from scale AE 0 (no improvement) to AE 100 (complete stain removal by composition). Additionally, the improvement on the anti-redeposition (ARD) effect is determined from ACIE Whiteness measured using a Minolta Spectrophotometer calibrated at D65/10+UV. The ACIE Whiteness is the difference between the CIE Whiteness of the reference (composition without varied component) and the composition. The CIE Whiteness scale is 0 (black) to 100 (white) and the ACIE Whiteness follows accordingly, i.e., the higher the value whiter results is obtained. In various embodiments, the improvement is at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, etc, up to 100. For example, the laundry composition may have a stain removal index of at least AE land an anti- redepositioning effect of at least ACIE 1 whiteness as determined using a Minolta Spectrophotometer. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.
[00142] In other embodiments, the composition has a filming and spotting performance of at least 3.5 as determined using ASTM D3556 or EN 50242:2016. Filming and spotting are estimated visually by trained panelists on a scale from 1 to 9 where 1 is poor performance and 9 is excellent performance. The usual target for commercial products is between 3 and 7. In various non-limiting embodiments, all values and ranges thereof, both whole and fractional, including and between those set forth above, are hereby expressly contemplated for use herein.

EXAMPLES
First Series of Examples
[00147] A first series of laundry compositions are formed and evaluated to determine stain removal index. More specifically, the following base formulation is utilized and various additives are added thereto.
Base Formulation:
Figure imgf000035_0001
Figure imgf000036_0003
[00148] Varying compositions were then created by adding amounts of the three additives described above. These compositions were then evaluated to determine Average %SRI scaled to no additive. The results are shown in FIG. 1 wherein the applied stain swatches are set forth below:
Figure imgf000036_0001
Compositions 1-6 are set forth below:
Figure imgf000036_0002
Figure imgf000037_0001
[00149] DTPMP is diethylenetriamine penta(methylene phosphonic acid).
[00150] GLDA is Tetrasodium glutamate diacetate.
[00151] Starch Polycarboxylate is starch polyacrylic hybrid polymer obtained as a reaction product between acrylic acid and maltodextrin, e.g. about 20 to about 30 weight or mol% acrylic acid and about 70 to about 80 weight or mol% maltodextrin.
[00152] Carboxymethyl Cellulose is a sodium carboxymethyl cellulose with the polysaccharide having an average molecular weight no greater than from about 10,000 to 80,000 Dalton and with the CMC component having a substitution degree from about 0.2 to about 1.5
[00153] The test conditions used to determine stain removal index are as follows:
Apparatus: Miele W1935 WPS, Front loader
9x PE container IL filled with 500 mL of water: water hardness 18°DH
1.667 grams of base formulation dosed to PE bottle containing 500ml water
(= 50 ml detergent/ machine wash cycle [15L] ) corrected for 17.5% hole in base formulation
Additives dosed in formulation hole
All purpose monitor supplied to each PE bottle
SM-04 Monitor ex CFT: 20 stains targeted on bleach, enzyme, stain removal, particle and fat
Washing program: cotton program 40°C , 90 minutes
After the wash cycle the monitors are removed from the containers and rinsed with tap water (20 minutes rinse cycle)
The monitors are dried overnight on tissue paper
The cleaning performance is measured (stain removal index) by measuring color before and after washing
[00154] The results of these evaluations are set forth in Figure 1.
Second Series of Examples
[00155] A second series of laundry compositions are formed and evaluated to determine antiredeposition (ARD) according to a procedure by using a Tergotometer. More specifically, whiteness is measured of knitted cotton. 18 dH water is used along with soil and detergent. Samples of the cotton are washed for 60 minutes at about 25°C/40°C at 200 rpm. Then a 15 minute rinse cycle is completed. CIE Whiteness scaled to a reference is measured using a Minolta Spectrophotometer.
[00156] More specifically, the following base formulation is utilized and various additives are added thereto.
Base Formulation:
Figure imgf000038_0001
[00157] The components in the table above are the same as described above.
[00158] Varying compositions were then created by adding amounts of the three additives described above. These compositions were then evaluated to determine CIE whiteness as described above. The results are shown in FIG. 2.
[00159] Compositions 7-13 are set forth below:
Figure imgf000038_0002
Figure imgf000039_0001
[00160] DTPMP is diethylenetriamine penta(methylene phosphonic acid).
[00161] GLDA is Tetrasodium glutamate diacetate.
[00162] HEDP is Hydroxyethylidene Diphosphonic Acid.
[00163] Starch polycarboxylate is starch polyacrylate hybrid polymer.
[00164] The results of the evaluations of the first and second series of compositions shows that: GLDA shows similar or better stain removal performance compared with DTPMP at the same dosage level. Moreover, the combination GLDA with biopolymers outperforms DTPMP for stain removal. Phosphonate shows rather poor ARD effect and the same accounts for GLDA without the biopolymer. In addition, the combination of GLDA with the biopolymer shows significant ARD performance improvement.
Third Series of Examples
[00165] A third series of examples, i.e., automatic dishwashing compositions, are formed and evaluated to determine primary and secondary washing performance (e.g. filming and spotting). The test conditions used are as follows:
Machines: Miele GSL2
Program: R65/10/K165
Running time ~lh 35 min, washing, 2 rinses and drying
Water hardness: 21 dGH
Made synthetic from CaCh, MgSO4 and NaHCO
Cycles: 5, 10, 20 and 30
Evaluation by a panel on filming and spotting
Used powder per cycle: 18.8 g
Ballast soil: 25 g
[00166] The ballast soil includes the following components:
Figure imgf000039_0002
Figure imgf000040_0001
[00167] The compositions of this third series are as follows:
Figure imgf000040_0002
Figure imgf000040_0003
Figure imgf000041_0001
[00168] Starch Polycarboxylate is a starch polyacrylic hybrid polymer obtained as a reaction product between acrylic acid and maltodextrin, e.g. about 20 to about 30 weight or mol% acrylic acid and about 70 to about 80 weight or mol% maltodextrin.
[00169] Polycarboxylate is acrylate copolymer sodium salt, e.g. about 45-65mol % of acrylic acid and about 30-45 mol% of maleic acid and an average MW of about 3000-4000 Daltons.
[00170] Each of these Compositions 14-21 were evaluated to determine filming and spotting after both 20 and 30 washes. More specifically, the results are set forth in the Figures as follows:
Results of 20 washes: See Figures 3-7; and
Results of 30 washes: See Figures 8-10.
[00171] The results show that phosphonate concentrations can be significantly reduced (to 0.1%) without losing secondary cleaning performance. Without phosphonate, significant filming and spotting is observed. The performance of Compositions 16-19 is comparable to Compositions 14, 15, 20, 21 at moderate phosphonate concentrations (0.5 - 1.5%), but not as good at very low phosphonate concentrations (-0.1%). With these formulations, a complete replacement of phosphonate brings a significant loss in filming performance.
