Description

Papermakinq Additive Compositions and Methods and Uses Thereof

[001] This application claims the benefit of priority and the filing date of U.S. Provisional Patent Application 62/208,662, filed on August 22, 2015, the content of which is hereby incorporated by reference in its entirety.

[002] Paper is an incredibly important, practical and versatile substance with tens of thousands of different paper-based products being produced yearly. Paper may be impregnated, enamelled, creped, waterproofed, waxed, glazed, sensitised, bent, folded, crumpled, cut, dissolved, macerated, moulded or embossed. Likewise, paper may be laminated with fabrics, plastics and metals. In an effort to organize, the vast array of products that can be made from paper can be classified into five broad categories: 1) newsprint and magazine; 2) printing and writing paper; 3) sanitary and household; 4) packaging material and products; and 5) specialized papers. Being such a natural part of our daily lives, we can sometimes forget just how much we rely upon this essential, renewable and evolving resource.

[003] The usefulness of paper products has made a significant impact of the global economy. In 2015, worldwide production of paper-based products was over 300 million tons and was valued at $500 billion. Corrugated and paperboard containers account for about 30% of industry revenue. Other major products include paperboard (15%), bags and coated and treated paper (10%) and sanitary paper products (5%). The global pulp and paper industry is a multi-billion dollar industry that is largely dominated by the United States and China, both accounting for over 40% of the world's total production. However, Japan, Germany, Canada, South Korea, Sweden, Finland, Brazil and Indonesia also have significant pulp and paper enterprises. Leading exporting and importing countries include the United States and Germany.

[004] In addition to being one of the dominating forces in the industry, the United States also consumes more paper-based products than any other country in the world, using a third, or about 100 million tons, of a paper-based products produced in 2015. This high use and consumption of paper-based products is important to the United States economy. In the United States, 450 manufacturing facilities produced products valued at nearly $2 billion. Around 150,000 persons are directly employed by the industry, creating a payroll approaching $10 billion. It is estimated that the pulp and paper industry is the tenth largest employer in the United States.

[005] The manufacturing of paper is a mature industry. The fundamental components and processes currently being used by the pulp and paper industry have been in place for almost a century. In addition, pulp processing and paper making is a high production volume that also uses huge amounts of natural resources such as water and wood, chemicals and energy to produce pulp and paper. As such, the maturity of the industry, the high production volume, the extensive use of material and energy resources as well as environmental regulations puts a severe economic strain on manufacturers. However, innovations improving or optimizing the productivity and/or efficiency of paper production are still significant and valuable. For example, due to the high volume of paper productions, innovation enhancing productivity and/or efficiency would translate into tens, if not hundreds, of millions of dollars in savings and/or increased profits. In addition, innovations reducing the large amounts of energy consumption as well as the generation Dale, Papermaking Additive Compositions and Methods and Uses Thereof

of large amounts of waste water effluent and waste by-products, would address important environmental concerns which would also lead to reduced environmental impact and economic relief. As such, there is a great need to improve the process of making paper.

[006] Accordingly, there is a great need for papermaking additives that are non-toxic, biodegradable and effective in improving or optimizing the productivity and/or efficiency of paper production.

[016] FIG. 2 shows refined fibers after treatment with a papermaking additive composition disclosed herein.

DETAILED DESCRIPTION

[017] Paper is made from cellulosic fibers obtained from plant materials, such as, e.g., wood from hardwood or softwood trees, rags, flax, cotton linters and/or bagasse. Reclaimed paper can be recycled to produce new paper products, where is often blended with virgin fibers. Synthetic materials may be used to impart special qualities to a finished paper product. Other products made from cellulosic fibers include diapers, rayon, cellulose acetate, and cellulose esters, which are used for cloth, packaging films, and explosives.

[018] Typical woods are comprised of about 40%-50% cellulose, 25%-35% hemicellulose, 15%-30% lignin and 2%-10% extractives. In making paper, one major step is to extract the cellulose from the remainder of the other components. In general, the higher amount of hemicellulose, lignin and extractives present in a paper product, the lower the quality.

[019] Many modern papermaking mills are roughly divided into five distinct operational phases: 1) the pulping phase; 2) the forming phase; 3) the pressing phase; 4) the drying phase; and 5) the calendering phase. The last four phases can be collectively referred to as the paper production phase. Raw materials are processed and refined in the pulping phase to isolate cellulose fibers from lignin, extractives and other raw material impurities and produce a wet slurry or pulp having about 99% water content called the furnish. In the forming phase, also known as the wet end, the furnish is dispersed onto a moving screen known as a fourdrinier wire in order to drain water from the furnish (by gravity or under vacuum) to form a continuous mesh of fibers. In the pressing phase, the fiber mesh then passes between large rolls loaded under high pressure to squeeze out as much water as possible to form a pressed sheet. The pressed sheet then enter drying phase where it passes through a series of steam heated drying cylinders which reduces the water Dale, Papermaking Additive Compositions and Methods and Uses Thereof

content down to a level of about 6%. Lastly, in the calendering phase the dried paper is smoothed and flattened under high loading and pressure using steel rollers to produce the finished untrimmed paper product. The untrimmed paper is wound into rolls for use on web-fed presses, such as newspaper presses, or slit and cut into lengths to make sheets of paper for sheet-fed presses.

[020] During the pulping phase, useful fibers are separated from lignin, extractives (e.g., oleoresins and waxes) and other raw material waste products using chemical and/or mechanical procedures. For example, in chemical procedures, raw material is processed into smaller particles, put into a pressurized kettle, called a digester, along with chemicals (white liquor) and water, and cooked with steam under high pressure. Cooking breaks down the lignin binding material which separates the cellulose fibers from the rest of the raw material. The separated raw material and spent cooking chemicals are then sent to a recovery process, where the pulping chemicals and energy are recovered via multiple evaporation steps for concentration of pulping waste liquid (black liquor) which can then be burned as fuel.

[021] In mechanical procedures, raw material passes through a grinder where it is ground against a water lubricated rotating stone or the heat generated by grinding softens the lignin binding the fibers and the mechanized forces separate the fibers to form groundwood. Alternatively, raw material passes through a refiner where it is subjected to intensive shearing forces between a rotating steel disc and a fixed plate. The discs have raised bars on their faces and pass each other with narrow clearance. This action separates the fibers from the rest of the raw material. The shearing action also unravels the fibers, causing the fibrils of the fibers to partially detach and bloom outward. Raw material can also be softened by heating (thermo- mechanical) or impregnated with a chemical treatment before entering the digester or refiner to facilitate fibrillation (chemical thermos-mechanical).

[022] Whether fiber separation occurs by chemical, mechanical, or a combination of both procedures, the processed pulp is pumped through a sequence of holding tanks commonly called chests for further processing. For example, the pulp can be washed to cleanse the fibers and remove residual lignin and other impurities as well as screened to remove any remaining fiber bundles and achieve a more uniform quality and consistency. The processed pulp can also be mixed in a blending chest with other processed pulp obtained from different raw material sources or recycled paper products in order to create a blended processed pulp. Depending on the type of final paper product being made, the processed pulp can also pass through a series of chests were various fillers are added to the processed pulp to improve, e.g., opacity, brightness, mechanical strength, smoothness, ink receptivity, as well as other properties. For example, bleach or other whitening agents may be added to whiten the fibers and increase brightness, dyes and pigments may be added to produce colored papers, opacity agents like calcium carbonate, clay and titanium dioxide increase opacity to enable printing on the both sides, a sizing agent may be added to increase moisture resistance. The processed pulp can also be treated to remove ink (deinking) and other contaminants, which typically is needed if the raw material was reclaimed paper products that are being recycled. Lastly, the processed pulp can have its pH adjusted and be diluted with waterto form a consistent furnish for subsequent processing. Dale, Papermaking Additive Compositions and Methods and Uses Thereof

[023] A major goal of the pulping phase is to remove as much lignin, extractives and otherwaste materials from the pulp in order to increase the amount of separated cellulose fibers present in the pulp, without sacrificing fiber integrity and strength in order to achieve a high fiber purity and quality. Another major goal of the pulping phase is to increasing the surface area of fibers to promoting bonding by, e.g., causing the fibrils of the fibers to partially detach and bloom outward. Additionally, particularly with respect to recycled paper, another goal is the removal of inks and adhesive contaminants, which can affect the purity and quality of the final paper product.

[024] Without wishing to be limited by its theory, the presently disclosed papermaking additive compositions dissolve, disperse, or otherwise disrupt one or more components of the raw materials used to make pulp. This mechanism of action appears, in part, to be tied to the ability of the papermaking additive compositions disclosed herein to break down lignin and/or facilitate the separation of individual cellulose and hemicellulose fibers from fiber bundles. The end result is improved separation of cellulose and hemicellulose fibers from fiber bundles which ultimately leads to the production of higher quality paper products in a more efficient and cost-effective manner. This mechanism of action also appears, in part, to be tied to the ability of the papermaking additive compositions disclosed herein to break down ink and other organic compounds considered impurities in raw materials obtained from reclaimed paper products.

[025] Regardless of the theory of operation, the disclosed papermaking additive compositions, methods and uses offer an alternative means of paper making that does not rely on chemicals toxic to humans or the environment. In addition, the disclosed papermaking additive compositions, methods and uses results in a better breakdown of lignin and other impurities that facilitates easier recycling of waste water for reuse in the pulping or paper production phases which also benefits humans and the environment. Further, the disclosed papermaking additive compositions, methods and uses to not require extensive energy input, thereby enabling a reduction of overall energy usage which further benefits humans and the environment. Rather the papermaking additive compositions, methods and uses disclosed herein appear to increase cellulose fiber separation, increase the surface area of fibers as well as, remove ink, adhesive and other contaminants, without sacrificing fiber integrity and strength in order to achieve a high fiber purity and quality. In addition, the disclosed papermaking additive compositions been proven to be substantially nontoxic to man and domestic animals and which have minimal adverse effects on wildlife and the environment.

[026] Aspects of the present specification disclose, in part, a papermaking additive composition. A papermaking additive composition disclosed herein comprises a treated fermented microbial supernatant and one or more non-ionic surfactants. The treated fermented microbial supernatant lacks any live microorganisms such as yeast or bacteria, and additionally, lacks any active enzymes, activatable proenzymes, or any enzymatic activity. Additionally, the papermaking additive composition itself lacks any live microorganisms such as yeast or bacteria, and additionally, lacks any active enzymes, activatable proenzymes, or any enzymatic activity. A papermaking additive composition disclosed herein may be used in any personal or commercial papermaking processes.

[027] In an aspect of this embodiment, a papermaking additive composition disclosed herein comprises, e.g., about 75% to about 99% of treated fermented microbial supernatant and about 1 %-25% of one or Dale, Papermaking Additive Compositions and Methods and Uses Thereof

more non-ionic surfactants. In another aspect of this embodiment, a papermaking additive composition disclosed herein comprises, e.g., about 80% to about 97% of treated fermented microbial supernatant and about 3%-20% of one or more non-ionic surfactants. In yet another aspect of this embodiment, a papermaking additive composition disclosed herein comprises, e.g., about 85% to about 95% of treated fermented microbial supernatant and about 5%-15% of one or more non-ionic surfactants. In still another aspect of this embodiment, a papermaking additive composition disclosed herein comprises, e.g., about

87% to about 93% of treated fermented microbial supernatant and about 7%-13% of one or more non-ionic surfactants. In another aspect of this embodiment, a papermaking additive composition disclosed herein comprises, e.g. , about 88% to about 92% of treated fermented microbial supernatant and about 8%-12% of one or more non-ionic surfactants. In another aspect of this embodiment, a papermaking additive composition disclosed herein comprises, e.g., about 89% to about 91 % of treated fermented microbial supernatant and about 9%-11 % of one or more non-ionic surfactants.

[028] Aspects of the present specification disclose, in part, a fermented microbial supernatant. A fermented microbial supernatant disclosed herein can be prepared by culturing a yeast strain, a bacterial strain, or a combination of both a yeast strain and a bacterial strain in a fermenting medium comprising a sugar source, a malt and a magnesium salt. In an aspect of this embodiment, only a single yeast strain is used in a fermenting medium. In another aspect of this embodiment, two or more different yeast strains are used in a fermenting medium. In yet another aspect of this embodiment, only a single bacterial strain is used in a fermenting medium. In still another aspect of this embodiment, two or more different bacterial strains are used in a fermenting medium. In another aspect of this embodiment, one or more different yeast strains are used in conjunction with one or more different bacteria in a fermenting medium. In yet another aspect of this embodiment, two, three, four, five or more different yeast strains are used in conjunction with two, three, four, five or more different bacteria in a fermenting medium.

[029] A sugar source includes, without limitation, sucrose from molasses, raw cane sugar, soybeans or mixtures thereof. Molasses generally contains up to about 50% sucrose in addition to reducing sugars such as glucose and maltase as well as ash, organic nonsugars and some water. The presence of the sugars of the type found in the molasses is important in encouraging the activity of the enzymes and the yeast bacteria by which they are produced. Although the untreated cane blackstrap molasses is preferred, other molasses such as beet molasses, barrel molasses and the like may also be used as a natural source of the materials required for the enzymatic fermentation. The amount of molasses useful in preparing a fermenting medium disclosed herein is between 40% and about 80% by weight, and preferably between about 55% and about 75% by weight. It will be appreciated that specific amounts of the molasses utilized may be varied to yield optimum compositions desired.

[030] Raw cane sugar is a sugar product which has not been refined and which contains residual molasses as well as other natural impurities. Although it is not clearly understood, it has been found that the presence of raw sugar in the fermentation reaction yields significantly improved properties as compared to the use of refined sugars which contain residual chemicals used in the decolorization and final purification and refinement which may have some deleterious effect on the yeast and malt enzymes. It has been found that optimum biological and enzymatic properties of the disclosed fermenting medium are improved where Dale, Papermaking Additive Compositions and Methods and Uses Thereof

a portion of the fermentable materials present in the mixture comprises raw sugar. The amount of raw cane sugar useful in preparing a fermenting medium disclosed herein may be about 10% and about 40% by weight, and preferably between about 10% and about 30% by weight. It will be appreciated that specific amounts of the raw cane sugar utilized may be varied to yield optimum compositions desired.

[031] The essential enzymes which advantageously contribute to the fermentation reaction are provided by the malt and the yeast and/or bacteria. The specific malt utilized is preferably a diastatic malt which contains enzymes including diastase, maltase and amylase. The malt also is believed to improve the activity of the yeast and/or bacteria in addition to contributing to the overall potency and activity of the enzymatic composition within the final product mixture. The amount of malt useful in preparing a fermenting medium disclosed herein may be between about 3% and about 15% by weight, and preferably between about 7% and about 12% by weight. It will be appreciated that specific amounts of the malt utilized may be varied to yield optimum compositions desired.

[032] Fermentation is a metabolic process that results in the breakdown of carbohydrates and other complex organic substances into simpler substances like sugars, acids, gases or alcohol. Fermentation can occurs in yeast, bacteria and mold. Fermentation includes ethanol fermentation and lactic acid fermentation. Lactic acid fermentation includes homolactic fermentation and heterolactic fermentation.

[033] A yeast refers to any fermentation fungi that can be produce the needed enzymes for a fermentation reaction that results in, for example the conversion of carbohydrates into carbon dioxide and alcohols. A number of enzymes are produced by the active yeast during the fermentation reaction and include both hydrolytic and oxidative enzymes such as invertase, catalase, lactase, maltase, carboxylase and others. Yeast include yeast strains useful in food processing fermentation, such as, e.g., bean-based fermentation, dough-based fermentation, grain-based fermentation, vegetable-based fermentation, fruit-based fermentation, honey-based fermentation, dairy-based fermentation, fish-based fermentation, meat-based fermentation and tea-based fermentation.

[035] Mold refer to any fermentation mold that can be produce the needed enzymes for a fermentation reaction that results in, for example the production of alcohols like ethanol or acids like acetic acid, lactic acid and/or succinic acid. A non-exhaustive list of particular mold genera useful in a fermentation reaction disclosed herein include, but is not limited, Aspergillus. A non-exhaustive list of particular mold species useful in a fermentation reaction disclosed herein includes, but is not limited, A. acidus, A. fumigatus, A. niger, A. oryzae, and A. sojae.

[036] It will be appreciated that actual amounts of the various types of enzymes produced will be dependent on a number of factors including the types of molasses and sugar used in preparing the fermentation mixture. However, again it is believed that, in utilizing the molasses and raw sugar, optimum enzyme yields and activity are obtained. In an embodiment, the amount of yeast useful in preparing a fermenting medium disclosed herein may be between about 0.2% and about 5% by weight, and preferably between about 1 % and about 3% by weight. It will be appreciated that specific amounts of the yeast utilized may be varied to yield optimum compositions desired.

[037] The presence of a small amount of inorganic catalyst such as a magnesium salt enhances the activity of the enzymes not only during the fermentation reaction but thereafter in the product composition in attacking and decomposing the organic waste materials. A preferred magnesium salt is magnesium sulfate. The amount of magnesium salt useful in preparing a fermenting medium disclosed herein may be between about 0.1 % and about 5% by weight, and preferably between about 1 % and about 3% by weight. It will be appreciated that specific amounts of the magnesium salt utilized may be varied to yield optimum compositions desired.

[038] To prepare a fermented microbial supernatant, the molasses, sucrose and magnesium salt are added to a suitable amount of warm water. Although the specific amount of water used is not particularly critical, typically suitable amounts of water are from about 2 to about 20 times the total weight of the other ingredients of the fermenting medium used in the fermentation reaction. This amount of water is sufficient to facilitate easy admixture as well as to activate the yeast, bacterial and/or mold and dissolve the other materials. In addition, the temperature of the water cannot be too hot such that the heat inactivates the malt and yeast enzymes needed for fermentation. Thus, for example, water temperatures greater than about 65 °C must be avoided and preferred temperatures are between about 25 °C to about 45 °C. The use of cold water may result in unduly slow fermentation reaction rates and, thus, should also be avoided where increased reaction rates are desired. After the molasses, sugar and magnesium salt are effectively mixed and dissolved, the malt and the yeast are added, the mixture stirred and allowed to set until fermentation is essentially complete. The reaction time may be between about 2 and about 5 days at temperatures between about 20 °C and about 45 °C. Completion may be readily ascertained by noting that the effervescence of the reacting mixture has substantially subsided. At the end of the fermentation reaction, the fermented microbial culture is centrifuged to remove the "sludge" formed during the fermentation. The resulting Dale, Papermaking Additive Compositions and Methods and Uses Thereof

production phase in order to remove ink from pulp and/or paper material produced by the pulping and/or the paper production phases.

[071] An impurity and/or contaminate typically comprise resins, waxes, fats, fatty acids and their esters, and unsaponifiable substances, photosterols, salts and other water-soluble substances and non-volatile hydrocarbons as well as inks, adhesives, plastics and other additives. Such impurities and/or contaminates are generally referred to as extractives. Inks are made up of pigment, pigment carrier and additives formulated to reduce smudging, picking and other printing problems associated with ink.

[072] The combination of the nonionic surfactant and the treated fermented microbial supernatant in the papermaking additive compositions disclosed herein results in an accelerated in situ chemical reactions of the molecular structures, particularly chemical bonds present in polysaccharide and lipid-based components, present in the raw materials used to make pulp and paper material, particularly chemical bonds and lipid-based components. The in situ chemical reactions dissolve, disperse, or otherwise disrupt one or more components of the raw material.

[073] Without wishing to be limited by any theory, upon application of a papermaking additive composition in an aqueous environment, highly reactive, uniquely structured, ultra-fine microbubbles are spontaneously formed. These "functionalized" microbubbles comprise an outer "highly reactive" shell composed of one or more nonionic surfactants and components from the treated fermented microbial supernatant and an inner core containing air. The "highly reactive" shell enables a dramatic increase in the mass transfer of oxygen in an aqueous environment and an accelerated bio-catalysis of the molecular structures of compounds, which in combination provide a synergistic functionality. With respect to mass transfer of oxygen, this functionality increases transfer rates of oxygen and raises the level of dissolved oxygen in an aqueous environment which far exceeding the solubility limits anticipated by Henry's Law, and, are at levels that simply cannot be achieved through mechanical aeration systems. It appears that components from the treated fermented microbial supernatant interfere with the ability of the nonionic surfactants to create a well- organized micellar shell. The result is a loose molecular packing of these fermentation components and surfactants that "functionalized" the shell to be more gas permeable, thereby creating more favorable conditions for mass gas transfer. As such, this oxygen transfer function increases the availability of oxygen in an aqueous environment. With respect to accelerated bio-catalysis, this functionality lowers the transition of energy required for a catalytic reaction to occur by providing a reaction platform that increases localized concentrations of reactants, enables donation of electrons and facilitate chemical reactions at electron poor sites. As such, this bio-catalysis function mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in a compound. As such, the "functionalized" shell of the microbubbles have catalytic activities that like conventional enzyme systems, but without the need of any enzymes. Thus, application of a papermaking additive composition disclosed herein creates "functionalized: microbubbles that increase oxygen dispersion resulting in higher dissolved oxygen levels and accelerate molecular interactions resulting in catalytic breakdown of compounds.

[074] When in contact with raw material used to make pulp, the "functionalized" shell chemically interacts with lignin and the lipid-based components of the material in a manner that enables donation of electrons Dale, Papermaking Additive Compositions and Methods and Uses Thereof

or reactions at electron poor sites that mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in lignin and other extractives. Similarly, when in contact with impurities or contaminants including ink the "functionalized" shell chemically interacts with the impurities and contaminants in a manner that enables donation of electrons or reactions at electron poor sites that mediates cleavage of chemical bonds, including glycosidic and ester bonds, present in the impurities and contaminants. These interactions appears to be a form of hydrolysis using beta-oxidation where, in addition to relying on components of the

"functionalized" shell, oxygen present in the core of the microbubble is also utilized. Thus, the properties present in the "functionalized" shell works synergistically with the oxygen transfer capabilities of the core to enhance the in situ breaking of chemical bonds, including glycosidic and ester bonds, present in lignin, extractives, impurities and contaminants.

[075] Application of a papermaking additive composition disclosed herein can be by any method that exposes a raw material, an impurity and/or a contaminant to the disclosed papermaking additive compositions in a manner that provides adequate breakage of bonds one or more components of the raw material, the impurity and/or the contaminant.

[078] Application of a papermaking additive composition disclosed herein is in an effective amount. An effective amount of a disclosed papermaking additive composition can be an amount sufficient achieve a high fiber purity and quality. In aspects of this embodiment, an effective amount causes an increase in cellulose fiber separation, an increase in the surface area of fibers, removal of an ink, an adhesive and/or other impurity or contaminant, or any combination thereof. Preferentially, such an effective amount will not harm fiber integrity and strength. The actual effective amount of a disclosed papermaking additive composition is determined by routine screening procedures employed to evaluate controlling activity and efficacy of a papermaking additive composition disclosed herein. Such screening procedures are well known by those skilled in the art. It is expected that a papermaking additive composition disclosed herein having a higher level of activity can be used in smaller amounts and concentrations, while those having a lower level of activity may require larger amounts or concentrations in order to achieve the same controlling effect.

[079] An effective amount of a papermaking additive composition disclosed herein can be assessed by the purity and quality of pulp and paper products produced. The Technical Association of Pulp and Paper Industry (TAPPI) and the International Organization for Standardization (ISO) have established standard methods of evaluating processed pulp purity and quality, see, e.g., TAPPI Standard T 203 cm-99 Alpha-, Beta- and Gamma-Cellulose in Pulp; TAPPI Standard T 235 cm-85 Alkali Solubility R10 and R18; TAPPI Standard T 430 cm-09 Copper Number of Pulp, Paper and Paperboard; TAPPI Standard T 236 cm-99 Kappa Number of Pulp; TAPPI Standard T 230 om-99 Viscosity of Pulp; TAPPI Standard T 452 om-08 Dale, Papermaking Additive Compositions and Methods and Uses Thereof

Standard T 204 cm-97 Solvent Extractives of Wood and Pulp; and TAPPI Standard T 21 1 om-93 Ash in

Wood Pulp, Paper and Paperboard: Combustion at 525°C.

[080] One aspect of high fiber purity and quality is pulp yield. Generally, the higher the yield of cellulosic material from the raw material the better the fiber purity and quality. Typical woods are comprised of about 40%-50% cellulose and 25%-35% hemicellulose. Extraction of over 70% cellulosic material is generally considered a high pulp yield.

[081] In an embodiment, an effective amount of a disclosed papermaking additive composition is an amount sufficient to cause a high pulp yield. In aspects of this embodiment, an effective amount of a disclosed papermaking additive composition is an amount sufficient to cause a pulp yield of, e.g., about 70%, about 75%, about 80%, about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91 %, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98% or about 99%. In other aspects of this embodiment, an effective amount of a disclosed papermaking additive composition is an amount sufficient to cause a pulp yield of, e.g., at least 70%, at least 75%, at least 80%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91 %, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99%.

In yet other aspects of this embodiment, a method or use disclosed herein results in a pulp yield of, e.g., about 70% to about 80%, about 70% to about 85%, about 70% to about 90%, about 70% to about 95%, about 70% to about 99%, about 75% to about 85%, about 75% to about 90%, about 75% to about 95%, about 75% to about 99%, about 80% to about 90%, about 80% to about 95%, about 80% to about 99%, about 85% to about 93%, about 85% to about 95%, about 85% to about 97%, about 85% to about 99%, about 90% to about 93%, about 90% to about 95%, about 90% to about 97%, about 90% to about 99%, about 93% to about 95%, about 93% to about 97%, about 93% to about 99%, about 95% to about 97% or about 95% to about 99%.

[082] In another embodiment, a method or use disclosed herein results in a high pulp yield. In aspects of this embodiment, a method or use disclosed herein results in a pulp yield of, e.g., about 70%, about 75%, about 80%, about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91 %, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98% or about 99%. In other aspects of this embodiment, a method or use disclosed herein results in a pulp yield of, e.g., at least 70%, at least 75%, at least 80%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91 %, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99%. In yet other aspects of this embodiment, a method or use disclosed herein results in a pulp yield of, e.g. , at most 70%, at most 75%, at most 80%, at most 85%, at most 86%, at most 87%, at most 88%, at most 89%, at most 90%, at most 91 %, at most 92%, at most 93%, at most 94%, at most 95%, at most 96%, at most 97%, at most 98% or at most 99%. In yet other aspects of this embodiment, Dale, Papermaking Additive Compositions and Methods and Uses Thereof

a method or use disclosed herein results in a pulp yield of, e.g. , about 70% to about 80%, about 70% to about 85%, about 70% to about 90%, about 70% to about 95%, about 70% to about 99%, about 75% to about 85%, about 75% to about 90%, about 75% to about 95%, about 75% to about 99%, about 80% to about 90%, about 80% to about 95%, about 80% to about 99%, about 85% to about 93%, about 85% to about 95%, about 85% to about 97%, about 85% to about 99%, about 90% to about 93%, about 90% to about 95%, about 90% to about 97%, about 90% to about 99%, about 93% to about 95%, about 93% to about 97%, about 93% to about 99%, about 95% to about 97% or about 95% to about 99%.

[083] Another aspect of high fiber purity and quality is the amount of alpha-, beta- and gamma-cellulose content present in the processed pulp or paper product produced. In general, alpha-cellulose is an indicator of intact, higher-molecular-weight cellulose content in pulp, beta-cellulose is an indicator of degraded cellulose, and the gamma-cellulose is an indicator of hemicellulose. There are several assays which measure cellulosic material content in processed pulp.

[084] In a cellulose content assay, alpha-, beta- and gamma-cellulose fractions are separated using a mercerizing caustic solution where alpha-cellulose remains insoluble, beta-cellulose is precipitated out of solution upon acid addition, and gamma-cellulose remains in solution. For example, alpha-cellulose is the pulp fraction resistant to 17.5% and 9.45% sodium hydroxide solution under conditions of the test. Beta- cellulose is the soluble fraction which is reprecipitated on acidification of the solution; gamma-cellulose is that fraction remaining in the solution. The soluble fractions containing beta-cellulose and gamma cellulose are determined volumetrically by oxidation with potassium dichromate and the alpha-cellulose, as the insoluble fraction, is derived by difference using the following formulas: AC% = 100 - [6.85(V2 - Vi) x N x 20] / A x W, where AC% is the percent alpha-cellulose, Vi is the titration, in milliliters, of the pulp filtrate, V2 is the titration, in milliliters, of the blank, N is the exact normality of the ferrous ammonium sulfate solution, A is the volume, in milliliters, of the pulp filtrate used in the oxidation, and W is the oven-dry weight, in grams, of the pulp specimen. GC% = [6.85 (V4 - V3) x N x 20] / (25 x W), where GC% is the percent gamma-cellulose, V3 is the titration, in milliliters, of the solution after precipitation of beta-cellulose, V4 is the titration, in milliliters, of the blank, N is the exact normality of the ferrous ammonium sulfate solution and W is the oven-dry weight, in grams, of the pulp specimen. BC% = 100 - (AC% + GC%), where BC% is the percent beta-cellulose, where AC% is the percent alpha-cellulose and where GC% is the percent gamma- cellulose. A standardized cellulose content assay is described in, e.g. , TAPPI Standard T 203 cm-99 Alpha- , Beta- and Gamma-Cellulose in Pulp, the content of which is hereby incorporated by reference in its entirety.

[085] In an alkali resistance assay, retention of cellulosic material using at least two different percent alkali solutions provide information on high molecular weight carbohydrates (intact cellulose or alpha- cellulose) in processed pulp. The alkali is typically sodium hydroxide and the concentrations most frequently used are 18%, 10%, and 5 % (m/m). For example, a 10% sodium hydroxide solution dissolves both degraded cellulose and hemicellulose which provides an indication on the total amount of insoluble cellulosic material (retention in 10% alkali or R10 value). As such, the R10 value includes the amount of alpha-cellulose (intact cellulose). However, only hemicellulose is soluble in an 18% sodium hydroxide solution which provides an estimate on the amount of both alpha- and beta-cellulose that remains in the Dale, Papermaking Additive Compositions and Methods and Uses Thereof

insoluble fraction (retention in 18% alkali or Ris value). To perform the alkali solubility assay, pulp, a known mass of oven-dried processed pulp is treated with sodium hydroxide solution for 60 minutes at 20°C, washed in acetic acid and the insoluble cellulosic material is dried and weighed. Alkali resistance, R_c, is expressed as a percentage by mass using the following formula: mi x 100 / mo, where R_c is alkali resistance, mo is the mass in grams of the test portion calculated on an oven dry basis, and mi is the oven dry mass in grams of the alkali-insoluble fraction. When the alkali resistance assay is performed using 10% alkali solutions, Rc is referred to as Rio, when performed using 18% alkali solutions, Rc is referred to as Ris. A standardized alkali solubility assay is described in, e.g., ISO Standard 699:2015 Pulps - Determination of

Alkali Resistance, the content of which is hereby incorporated by reference in its entirety.

[086] In an alkali solubility assay, solubility of cellulosic material at two different percent alkali solutions provide information on low molecular weight carbohydrates (degraded cellulose or beta-cellulose) and hemicellulose in processed pulp. The alkali is typically sodium hydroxide and the concentrations most frequently used are 18% and 10% (m/m). For example, a 10% sodium hydroxide solution dissolves both degraded cellulose and hemicellulose which provides an indication on the total amounts of soluble cellulosic material in basic solutions (solubility in 10% alkali or Sio value). As such, the Sio value includes the sum of hemicellulose and beta-cellulose (degraded cellulose). However, hemicellulose is soluble in an 18% sodium hydroxide solution which provides an estimate on the amount of residual hemicellulose present in the pulp (solubility in 18% alkali or Sie value). As such, beta-cellulose (degraded cellulose) can be determined by subtracting the Sio value from the Sie value (Sie minus Sio). In addition, alpha-cellulose content can be calculated based on the alkali solubility assay by determining the total amount of cellulosic material and subtracting the Sio value. To perform the alkali solubility assay, pulp is treated with sodium hydroxide solution and oxidation of the dissolved organic matter with potassium dichromate. Ammonium iron(ll) sulphate is used to titrate excess potassium dichromate and the amount of potassium dichromate consumed is used to calculate the cellulose equivalent. The soluble fraction of cellulose is expressed as a percentage by mass of the oven-dry pulp using the following formula: S_c = 6.85 (V2 - Vi) x c x 100 / m x V, where S_c is alkali solubility, V is the volume, in milliliters, of filtrate used in the oxidation, Vi is the volume, in milliliters, of ammonium iron(ll) sulphate solution consumed in the titration of the test solution, V2 is the volume, in milliliters, of ammonium iron(ll) sulphate solution consumed in the blank test, c is the concentration, in moles per liter, of the ammonium iron(ll) sulphate solution, m is the mass, in grams, of the test portion calculated on an oven-dry basis; and 6.85 is the empirical factor, in milligrams, indicating the amount of cellulose equivalent to 1/6 mol of potassium dichromate. When the alkali solubility assay is performed using 10% alkali solutions, S_c is referred to as S10, when performed using 18% alkali solutions, Sc is referred to as Sie. Standardized alkali solubility assays are described in, e.g., TAPPI Standard T 235 cm-09 Alkali Solubility of Pulp at 25°C and ISO Standard 692 Pulps - Determination of Alkali Solubility, the content of each of which is hereby incorporated by reference in its entirety.

[087] In a pulp viscosity assay, the viscosity of processed pulp is determined. The viscosity of a pulp is an indicator of the average degree of polymerization of the cellulose. Higher pulp viscosity is an indicator of longer cellulose chain length and lesser degradation. As such, the higher the pulp viscosity the more intact, higher-molecular-weight cellulose (alpha-cellulose) is present in the processed pulp and, conversely, the less degraded cellulose (beta-cellulose) that is present in the pulp. A standardized pulp viscosity assay Dale, Papermaking Additive Compositions and Methods and Uses Thereof

is described in, e.g., TAPPI Standard T 230 om-99 Viscosity of Pulp, the content of which is hereby incorporated by reference in its entirety.

[096] Another aspect of high fiber purity and quality is the amount of lignin, extractives and other impurities present in the processed pulp or paper product produced. In general, the lower the amount of lignin, extractives and other impurities in pulp, the higher the purity and integrity of cellulosic material in Dale, Papermaking Additive Compositions and Methods and Uses Thereof

processed pulp. Typical woods are comprised of about 15%-30% lignin and 2%-10% extractives. There are several assays which measure lignin content in processed pulp.

[097] In the Kappa number assay, the kappa number is an indicator of the hardness, bleachability and delignification of the processed pulp. The kappa number is defined as the volume in milliliters of 0.1 N potassium permanganate (KMnC ) consumed by one gram of moisture-free pulp in an acidic medium under defined time and temperature conditions. The Kappa number has a range of 1 to 100 and is an assessment of how much lignin is present in pulp, which determines the amount of bleach that needs to be added to it if the goal is a white processed paper product. High Kappa numbers require more bleach, while lower numbers have less lignin and need less bleach. To perform the Kappa number assay, a known quantity of processed pulp is allowed to react with equal amounts of 4 N sulfuric acid and 0.1 N potassium permanganate solution for a given time. The amount of pulp is chosen so that about 50% of the total oxidation capacity of the permanganate is left unconsumed at the end of the reaction time. Potassium iodine solution is added to the test solution and sodium thiosulphate is then used to titrate excess iodine and the amount of potassium permanganate consumed is used to calculate the lignin equivalent. Kappa number, K, is determined using the following formula: K = p x f / w and p = (b - a)N / 0.1 , where K is the Kappa number, f is a factor for correction to a 50% permanganate consumption, dependent on the value of p, w is the weight, in grams, of moisture-free pulp in the specimen, p is the amount, in milliliters, of 0.1 N permanganate actually consumed by the test specimen, b is the amount, in milliliters, of the thiosulfate consumed in the blank determination, a is the amount, in milliliters, of the thiosulfate consumed by the test specimen, and N is the normality of the thiosulfate. The Kappa number for bleachable pulps are in the range of 25-30, sack paper pulps in the range 45-55 and pulps for corrugated fiberboard are in the range 60-90. The Kappa number can also monitor the effectiveness of the lignin-extraction from processed pulp because the number is approximately proportional to the residual lignin content of the pulp. The following formula can be used: K = cl, where K is the Kappa number, c is a constant having the value of about 6.57, depending on process and raw material used, and I is the lignin content in percent. Standardized kappa number assays are described in, e.g., TAPPI Standard T 236 cm-99 Kappa Number of Pulp, ISO Standard 302:2015 Determination of Kappa Number and Chai and Zhu, Rapid Pulp Kappa Number Determination Using Spectrophotometry, J. Pulp Paper Sci. 25(1 1): 387-394 (1999), the content of each of which is hereby incorporated by reference in its entirety.

[098] In the copper number assay, the copper number is an indicator of the reducing groups of cellulosic material and impurities possessing reducing properties that are present in the processed pulp. Hydrolyzed or oxidized cellulose is capable of reducing certain metallic ions to lower valence states, and reactions of this type have served to detect damage to cellulose and to estimate the quantity of reducing groups. Thus, the copper number can be regarded as an index of those impurities in cellulose such as oxycellulose, hydrocellulose, lignin, and sugars which possess reducing properties. As such, this assay is valuable for detecting changes accompanying deterioration and may, therefore, be considered as a test for indicating the permanence of paper. Copper number is defined as the number of grams of metallic copper (as CU2O) resulting from the reduction of CUSC by 100.00 g of pulp fibers. To perform the copper number assay, pulp, a known mass of oven-dried processed pulp is treated with a CUSC solution and a carbonate- bicarbonate solution heated at 100°C for three hours with occasional shaking and then washed in in 5% Dale, Papermaking Additive Compositions and Methods and Uses Thereof

Na2C03 and then hot water. The treated cellulosic material is then incubated with phosphomolybdic acid, macerated, washed with water until the blue color of the fibers is removed, and the filtrate diluted to an appropriate volume and then titrated with 0.05 N KMnC to a faint pink end point. The copper number, C, is calculated using the following formula: C = 6.357 x (V - B) x N / W, where C is the copper number, V is the volume, in milliliters, of KMnC solution to titrate the filtrate from the specimen, B is the volume, in milliliters, of KMnC solution to titrate the blank filtrate, N is the normality of 0.05 N KMnC , W is the weight, in grams, of the oven-dried pulp. A standardized alkali solubility assay is described in, e.g., TAPPI Standard

T 430 cm-09 Copper Number of Pulp, Paper and Paperboard, the content of which is hereby incorporated by reference in its entirety.

[0103] Another aspect of high fiber purity and quality is the content of carboxyl groups present in the processed pulp. In general, the higher the number carboxyl groups, the higher the purity and integrity of cellulosic material in processed pulp. There are several assays which measure number of carboxyl groups in cellulosic material from processed pulp.

[0104] In the carboxyl content assay, the carboxyl content of processed pulp is determined, which is an indicator of paper strength, delignification and the number of times the cellulose fiber could be recycled. Carboxyl groups are beneficial in the bonding of pulp fibers in paper, which contributes to paper strength. The higher the carboxyl group content, the greater the paper strength will be. To perform the carboxyl content assay, dried processed pulp is mixed with 0.1 M HCI for 60 minutes and then filtered and washed with water. The treated cellulosic material is then added to a 250 mL of 1 mM NaCI solution which is Dale, Papermaking Additive Compositions and Methods and Uses Thereof

acidified with 1 .5 mL 0.1 M HCI, and then titrated conductometrically with 0.05 N NaOH at 0.2 mL increments. The titration data was plotted as conductivity versus volume to determine the milli-equivalent of acid groups per kilogram of pulp. The carboxyl group content, Co, is calculated using the following formula: Co = N x V x 100 / M, where Co is carboxyl group content (meq/100 g pulp), N is the titrant concentration, V is the volume, in milliliters at the equivalence point, and M is the mass, in grams, of the oven -dried pulp.

[0107] Another aspect of high fiber purity and quality is the brightness of the processed pulp or paper product produced. In general, the higher the brightness, the higher the purity and integrity of cellulosic material in processed pulp or paper product produced. There are several assays which measure number of carboxyl groups in cellulosic material from processed pulp.

[0108] Brightness is a numerical value of the reflectance factor of a sample with respect to blue light of specific spectral and geometric characteristics. Blue-light reflectance measurements were originally designed to provide an indication of the amount of bleaching that has taken place in the manufacture of pulp. This procedure is applicable to all naturally-colored pulps, and papers and board made therefrom. Brightness is based on a scale of zero to 100, with a higher blue-light reflectance number indicating the whiter the paper products will appear. To perform a brightness assay, a paper sample is exposed to a laser with a wavelength of 457 nm and a width of 44 nm and the amount of blue light having a wavelength of 457 nm reflected from the surface of a paper is measured. Standardized brightness assays are described in, Dale, Papermaking Additive Compositions and Methods and Uses Thereof

e.g., TAPPI Standard T 452 om-08 Brightness of Pulp, Paper, and Paperboard (directional reflectance at

457 nm) and ISO 2470: 2009 Measurement of Diffuse Blue Reflectance Factor (ISO Brightness), the content of which is hereby incorporated by reference in its entirety.

[0109] In an embodiment, an effective amount of a disclosed papermaking additive composition is an amount sufficient to result in a processed pulp or paper product derived from such pulp to have a high brightness. In aspects of this embodiment, an effective amount of a disclosed papermaking additive composition is an amount sufficient to result in a processed pulp or paper product derived from such pulp to have a brightness of, e.g. , about 70%, about 75%, about 80%, about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91 %, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98% or about 99%.

[0110] In an embodiment, a method or use disclosed herein results in a processed pulp or paper product derived from such pulp to have a high brightness. In aspects of this embodiment, a method or use disclosed herein results in a processed pulp or paper product derived from such pulp to have a brightness of, e.g., about 70%, about 75%, about 80%, about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91 %, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98% or about 99%. In aspects of this embodiment, a method or use disclosed herein results in a processed pulp or paper product derived from such pulp to have a brightness of, e.g., at least 70%, at least 75%, at least 80%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91 %, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99%.

99%. In yet other aspects of this embodiment, a method or use disclosed herein results in a processed pulp having an alpha-cellulose content of, e.g., about 70% to about 80%, about 70% to about 85%, about

70% to about 90%, about 70% to about 95%, about 70% to about 99%, about 75% to about 85%, about

93% to about 99%, about 95% to about 97% or about 95% to about 99%.

[0111] Another aspect of high fiber purity and quality is the amount of impurity and/or contaminate content of the processed pulp or paper product produced. In general, the lower the impurity and/or contaminate content, the higher the purity and integrity of cellulosic material in processed pulp or paper product produced. There are several assays which measure number of carboxyl groups in cellulosic material from processed pulp.

[0112] Another aspect of high fiber purity and quality is the ink content of the processed pulp or paper product produced. In general, the lower the ink content, the higher the purity and integrity of cellulosic material in processed pulp or paper product produced. There are several assays which measure number of ink content in cellulosic material from processed pulp or paper product produced.

[0113] Since the pulping phase usually removes most water-soluble and volatile compounds soluble in organic solvents, impurities and/or contaminates typically comprise resin and fatty acids and their esters, waxes and unsaponifiable substances as well as impurities and/or contaminates of reclaimed paper products such as inks, plastics and other additives. Such impurities and/or contaminates are generally referred to as extractives.

[0114] In a solvent extractive assay, the extractive content of processed pulp is determined, which is an indicator of paper strength, delignification and the number of times the cellulose fiber could be recycled. Solvent extractive assays include a dichloromethane-based assay and an ethanol-benzene assay. The dichloromethane-extractable content of a processed pulp is a measure of waxes, fats, resins, photosterols and non-volatile hydrocarbons. The ethanol-benzene extractable content of a processed pulp include dichloromethane-insoluble components including low-molecular weight carbohydrates, salts and other water-soluble substances in addition to waxes, fats, resins, photosterols and non-volatile hydrocarbons. To perform a solvent extractive assay, dried processed pulp is mixed with the appropriate solvent and the sample is heated in an extraction apparatus for not less than 24 extraction cycles over a period of about 4 to about 5 hours. The sample is removed from the apparatus and any remaining solvent is evaporated and the sample is then oven dried. The extractive content, E%, is calculated using the following formula: E% = [(We - Wb) / Wp] x 100, where E% is extractive content, W_e is the oven-dry weight, in grams, of extract, W is the oven-dry weight, in grams, of blank residue, and W is the oven-dry weight, in grams, of the initial pulp sample. Standardized solvent extractive assays are described in, e.g., TAPPI Standard T 204 cm-97 Solvent Extractives of Wood and Pulp, the content of each of which is hereby incorporated by reference in its entirety.

[0120] Application of a papermaking additive composition disclosed herein can be achieved by any process that effectively creates microbubbles as disclosed herein. The microbubbles formed with the papermaking additive composition disclosed herein appear to increase the mass transfer of oxygen in liquids. Without being bound by scientific theory, there are several possible explanations for this difference. First, the surfactants formulated into a papermaking additive composition disclosed herein include nonionic surfactants and/or biosurfactants which significantly alter the properties of bubble behavior. Second, a papermaking additive composition disclosed herein requires a much lower concentration of surfactants for microbubble formation. It has been suggested that surfactant concentrations must approach the critical micelles concentration (CMS) of a surfactant system. In a papermaking additive composition disclosed herein, microbubbles are formed below estimated CMCs for the surfactants used. This suggests that the microbubbles are the result of aggregates of surfactant molecules with a loose molecular packing more favorable to gas mass transfer characteristics. A surface containing fewer surfactant molecules would be more gas permeable than a well-organized micelle containing gas. Regardless of the mechanism, the tendency of a papermaking additive composition disclosed herein to organizes into clusters, aggregates, or gas-filled bubbles provides a platform for reactions to occur by increasing localized concentrations of reactants, lowering the transition of energy required for a catalytic reaction to occur, or some other mechanism which has not yet been described.

Example 6

Pulping Experiment

[0138] This example shows an increase in the efficiency of a pulping process by applying a papermaking additive composition as disclosed herein.

[0139] Initially, a crude pulp preparation was processed without the addition of a papermaking additive composition in a laboratory minipulper for 45 minutes. The crude pulp preparation comprised 17% raw materials. After pulping, preparation was assessed for freeness using the Canadian Standard. There was no disintegration of the raw materials, so it was not possible to sample or make freeness measurements.

[0140] In a subsequent experiment, a 17% crude pulp preparation was processed with a paper additive composition disclosed herein in a laboratory minipulper. The amount of a papermaking additive composition added was 300 mL per ton of raw material. Samples of this preparation were taken at 10 minutes, 20 minutes and 30 minutes. After pulping, preparation was assessed for freeness using the Canadian Standard. A time-dependent improvement in freeness was observed. At 10 minutes pulping although tiggering was observed, more contact time was required to achieve better homogenization of fibers (FIG. 1A). At 20 minutes pulping, continued improvement in tiggering was seen (FIG 1 B), while at 30 minutes pulping, excellent homogenization of fibers was observed (FIG. 1 C). These results show that a papermaking additive composition disclosed herein significantly improved the pulping process and resulted in excellent homogenization of fibers. Dale, Papermaking Additive Compositions and Methods and Uses Thereof

[0141] Subsequent micrographs of fibers treated with a papermaking additive composition disclosed herein show improved internal and external fibrillation on the fiber surface which leads to increase surface area and improved ability to form interfiber and intrafiber bonds (FIG. 2).

[0142] These experiments were repeated using the following concentrations: 30 mL papermaking additive composition per ton of raw material, 60 mL papermaking additive composition per ton of raw material and 400 mL papermaking additive composition per ton of raw material. All concentrations gave results similar to the 300 mL papermaking additive composition per ton of raw material concentration.

[0145] In closing, it is to be understood that although aspects of the present specification are highlighted by referring to specific embodiments, one skilled in the art will readily appreciate that these disclosed embodiments are only illustrative of the principles of the subject matter disclosed herein. Therefore, it should be understood that the disclosed subject matter is in no way limited to a particular compound, composition, article, apparatus, methodology, protocol, and/or reagent, etc., described herein, unless expressly stated as such. In addition, those of ordinary skill in the art will recognize that certain changes, modifications, permutations, alterations, additions, subtractions and sub-combinations thereof can be made in accordance with the teachings herein without departing from the spirit of the present specification. It is therefore intended that the following appended claims and claims hereafter introduced are interpreted to include all such changes, modifications, permutations, alterations, additions, subtractions and subcombinations as are within their true spirit and scope.

[0146] Certain embodiments of the present invention are described herein, including the best mode known to the inventors for carrying out the invention. Of course, variations on these described embodiments will become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventor expects skilled artisans to employ such variations as appropriate, and the inventors intend for the present invention to be practiced otherwise than specifically described herein. Accordingly, this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted Dale, Papermaking Additive Compositions and Methods and Uses Thereof

by applicable law. Moreover, any combination of the above-described embodiments in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.

[0147] Groupings of alternative embodiments, elements, or steps of the present invention are not to be construed as limitations. Each group member may be referred to and claimed individually or in any combination with other group members disclosed herein. It is anticipated that one or more members of a group may be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.

[0148] Unless otherwise indicated, all numbers expressing a characteristic, item, quantity, parameter, property, term, and so forth used in the present specification and claims are to be understood as being modified in all instances by the term "about." As used herein, the term "about" means that the characteristic, item, quantity, parameter, property, or term so qualified encompasses a range of plus or minus ten percent above and below the value of the stated characteristic, item, quantity, parameter, property, or term. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary. For instance, as mass spectrometry instruments can vary slightly in determining the mass of a given analyte, the term "about" in the context of the mass of an ion or the mass/charge ratio of an ion refers to +/-0.50 atomic mass unit. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical indication should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

[0149] Use of the terms "may" or "can" in reference to an embodiment or aspect of an embodiment also carries with it the alternative meaning of "may not" or "cannot." As such, if the present specification discloses that an embodiment or an aspect of an embodiment may be or can be included as part of the inventive subject matter, then the negative limitation or exclusionary proviso is also explicitly meant, meaning that an embodiment or an aspect of an embodiment may not be or cannot be included as part of the inventive subject matter. In a similar manner, use of the term "optionally" in reference to an embodiment or aspect of an embodiment means that such embodiment or aspect of the embodiment may be included as part of the inventive subject matter or may not be included as part of the inventive subject matter. Whether such a negative limitation or exclusionary proviso applies will be based on whether the negative limitation or exclusionary proviso is recited in the claimed subject matter.

[0150] Notwithstanding that the numerical ranges and values setting forth the broad scope of the invention are approximations, the numerical ranges and values set forth in the specific examples are reported as precisely as possible. Any numerical range or value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Recitation of numerical ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate numerical value falling within the range. Unless otherwise indicated herein, Dale, Papermaking Additive Compositions and Methods and Uses Thereof

each individual value of a numerical range is incorporated into the present specification as if it were individually recited herein.

[0151] The terms "a," "an," "the" and similar references used in the context of describing the present invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Further, ordinal indicators - such as "first," "second," "third," etc. - for identified elements are used to distinguish between the elements, and do not indicate or imply a required or limited number of such elements, and do not indicate a particular position or order of such elements unless otherwise specifically stated. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., "such as") provided herein is intended merely to better illuminate the present invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the present specification should be construed as indicating any non-claimed element essential to the practice of the invention.

[0152] When used in the claims, whether as filed or added per amendment, the open-ended transitional term "comprising" (and equivalent open-ended transitional phrases thereof like including, containing and having) encompasses all the expressly recited elements, limitations, steps and/or features alone or in combination with unrecited subject matter; the named elements, limitations and/or features are essential, but other unnamed elements, limitations and/or features may be added and still form a construct within the scope of the claim. Specific embodiments disclosed herein may be further limited in the claims using the closed-ended transitional phrases "consisting of or "consisting essentially of in lieu of or as an amended for "comprising." When used in the claims, whether as filed or added per amendment, the closed-ended transitional phrase "consisting of excludes any element, limitation, step, or feature not expressly recited in the claims. The closed-ended transitional phrase "consisting essentially of limits the scope of a claim to the expressly recited elements, limitations, steps and/or features and any other elements, limitations, steps and/or features that do not materially affect the basic and novel characteristic(s) of the claimed subject matter. Thus, the meaning of the open-ended transitional phrase "comprising" is being defined as encompassing all the specifically recited elements, limitations, steps and/or features as well as any optional, additional unspecified ones. The meaning of the closed-ended transitional phrase "consisting of is being defined as only including those elements, limitations, steps and/or features specifically recited in the claim whereas the meaning of the closed-ended transitional phrase "consisting essentially of is being defined as only including those elements, limitations, steps and/or features specifically recited in the claim and those elements, limitations, steps and/or features that do not materially affect the basic and novel characteristic(s) of the claimed subject matter. Therefore, the open-ended transitional phrase "comprising" (and equivalent open-ended transitional phrases thereof) includes within its meaning, as a limiting case, claimed subject matter specified by the closed-ended transitional phrases "consisting of or "consisting essentially of." As such embodiments described herein or so claimed with the phrase "comprising" are expressly or inherently unambiguously described, enabled and supported herein for the phrases "consisting essentially of and "consisting of."
