Description

[Technical field]

[0001] The present disclosure relates to fabric conditioning compositions comprising poly alpha-1,3-glucan ether compounds and depositable actives, where the poly alpha-1,3-glucan ether compounds can be characterized by a particular molecular weight and degree of cationic substitution. The present disclosure also relates to methods of using and making such compositions. [Background technology]

[0002] Cationic polymers can be useful in household care compositions, such as fabric conditioning compositions, because they can promote improved conditioning benefits, which can include improved feel or freshness.

[0003] In particular, cationic polysaccharides may be preferred by manufacturers and / or consumers because they are usually derived from natural sources or raw materials and are therefore viewed as sustainable and environmentally friendly materials. However, certain cationic polysaccharides present processing or formulation challenges. For example, some cationic polysaccharides may cause undesirable viscosity increases or may be incompatible with other ingredients, such as cellulase enzymes. Summary of the Invention [Problem to be solved by the invention]

[0004] There is a continuing need for improved fabric conditioning compositions that include cationically substituted polysaccharides. [Means for solving the problem]

[0007] The present disclosure also relates to a fabric conditioning composition comprising a poly alpha-1,3-glucan ether compound derived from a polysaccharide backbone having a degree of cationic substitution of from about 0.15 to about 0.8, preferably from about 0.3 to about 0.7, or from about 0.3 to about 0.6, or from about 0.4 to about 0.6, or from about 0.4 to about 0.5, and characterized by a weight average molecular weight determined prior to substitution of from about 90 kilodaltons to about 190 kilodaltons, and further comprising a depositable conditioning active selected from a softness active, a freshness active, or a combination thereof.

[0008] The present disclosure further provides a poly alpha-1,3-glucan ether compound represented by the following structure:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present disclosure relates to fabric conditioning compositions containing certain cationic substituted poly alpha-1,3-glucan ether compounds, which are glucan polymers characterized by having alpha-1,3-glycosidic bonds. These compounds are polysaccharides, are generally cellulase compatible, and can be provided in a wide range of molecular weights and degrees of substitution. Such cationic compounds are disclosed to provide rheology or viscosity modifying benefits.

[0012] As such, it has been surprisingly found that the selection of certain cationic poly alpha-1,3-glucan ether compounds can provide performance benefits in the context of fabric conditioning compositions. More specifically, it has been found that such compounds, characterized by a particular molecular weight and / or degree of substitution, can improve the performance of certain depositable actives, such as those that provide feel or freshness benefits, on fabrics.

[0013] The compositions, the polymers contained therein, and related methods are discussed in more detail below.

[0014] As used herein, the articles "a" and "an" when used in a claim are understood to mean one or more of what is claimed or described. As used herein, the terms "include", "includes" and "including" are meant to be non-limiting. The compositions of the present disclosure may comprise, consist essentially of, or consist of the components of the present disclosure.

[0015] The terms "substantially free of" or "substantially free from" may be used herein. This means that the indicated material is in minimal amounts and has not been intentionally added to the composition to form part of the composition, or preferably is not present at analytically detectable concentrations. It means that the indicated material is present only as an impurity in one of the other intentionally included materials. The indicated material may be present, if at all, at a concentration of less than 1%, or less than 0.1%, or less than 0.01%, or 0% by weight of the composition.

[0016] As used herein, the phrase "fabric conditioning composition" includes compositions and formulations designed to treat fabric with conditioning agents.Such compositions include, but are not limited to, laundry cleaning compositions and detergents, fabric softening compositions, fabric enhancing compositions, fabric deodorizing compositions, laundry pre-cleaning agents, laundry pre-treatment agents, laundry additives, spray products, dry cleaning agents or compositions, laundry rinse additives, cleaning additives, post-rinse fabric treatment agents, ironing aids, unit dose formulations, delayed delivery formulations, detergents contained on or in porous substrates or nonwoven sheets, and other suitable forms that may be obvious to those skilled in the art in light of the teachings herein.Such compositions can be used as laundry pre-treatment agents, laundry post-treatment agents, or can be added during the rinse or wash cycle of laundry operations.

[0017] The terms "poly alpha-1,3-glucan", "alpha-1,3-glucan polymer", "polyglucan" and "glucan polymer" are used interchangeably herein. Poly alpha-1,3-glucan is a polymer containing glucose monomer units linked together by glycosidic bonds (i.e., glycosidic bonds), at least about 50% of which are alpha-1,3-glycosidic bonds. Poly alpha-1,3-glucan is a type of polysaccharide. The general structure of poly alpha-1,3-glucan can be illustrated as follows:

[0018] [ka]

[0019] The poly alpha-1,3-glucan that can be used to prepare the poly alpha-1,3-glucan ether compounds of the present invention can be prepared using chemical methods. Alternatively, it can be prepared by extracting it from various organisms, such as fungi, that produce poly alpha-1,3-glucan. In addition, poly alpha-1,3-glucan can be enzymatically produced from sucrose using one or more glucosyltransferase (gtf) enzymes (e.g., gtfJ), as described, for example, in U.S. Patent No. 7,000,000 and U.S. Patent Application Publication Nos. 2013 / 0244288 and 2013 / 0244287 (all of which are incorporated herein by reference).

[0020] The percentage of glycosidic bonds between glucose monomer units of the poly alpha-1,3-glucan used to prepare the poly alpha-1,3-glucan ether compounds herein that are alpha-1,3 is at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% (or any integer value between 50% and 100%). Thus, in such embodiments, the poly alpha-1,3-glucan has less than about 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, 1%, or 0% (or any integer value between 0% and 50%) of glycosidic bonds that are not alpha-1,3.

[0021] The poly alpha-1,3-glucan used herein to generate the poly alpha-1,3-glucan ether compound is preferably linear / unbranched. In certain embodiments, the poly alpha-1,3-glucan has no branch points or has less than about 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% branch points as a percentage of glycosidic bonds in the polymer. Examples of branch points include alpha-1,6 branch points, such as those present in mutant polymers.

[0022] The terms "glycosidic bond" and "glycosidic linkage" are used interchangeably herein and refer to a type of covalent bond that binds a carbohydrate (sugar) molecule to another group, such as another carbohydrate. As used herein, the term "α-1,3-glycosidic bond" refers to a type of covalent bond that binds α-D-glucose molecules to each other via carbons 1 and 3 in adjacent α-D-glucose rings. This bond is shown in the poly α-1,3-glucan structure provided above. In this specification, "α-D-glucose" is referred to as "glucose".

[0023] The terms "poly alpha-1,3-glucan ether compound", "poly alpha-1,3-glucan ether", and "poly alpha-1,3-glucan ether derivative" are used interchangeably herein. The poly alpha-1,3-glucan ether compound herein can be represented by the following structure:

[0024] [ka]

[0025] In this structural formula, n can be about 425 to about 1200, and each R can be independently a hydrogen atom (H) or a positively charged organic group. The poly α-1,3-glucan ether compounds herein can have a degree of substitution of about 0.15 to about 0.8. Given that the poly α-1,3-glucan ether compounds herein have one or more positively charged organic groups, these compounds can be considered to be "cationic."

[0026] As used herein, a "positively charged organic group" refers to a chain of one or more carbons ("carbon chain") having one or more hydrogens replaced with another atom or functional group (i.e., a "substituted alkyl group"), where one or more of the replacements is a positively charged group. When a positively charged organic group has replacements in addition to replacements with positively charged groups, such additional replacements may have one or more hydroxyl groups, oxygen atoms (thereby forming aldehyde or ketone groups), alkyl groups, and / or additional positively charged groups. A positively charged organic group has a net positive charge because it contains one or more positively charged groups.

[0027] The terms "positively charged group," "positively charged ionic group," and "cationic group" are used interchangeably herein. Positively charged groups include cations (positively charged ions). Examples of positively charged groups include substituted ammonium groups.

[0028] The terms "substituted ammonium group," "substituted ammonium ion," and "substituted ammonium cation" are used interchangeably herein. A substituted ammonium group herein can include Structure I:

[0029] [ka]

[0030] R2, R3, and R4 in Structure I may each independently represent a hydrogen atom or an alkyl, aryl, cycloalkyl, aralkyl, or alkaryl group. The carbon atom (C) in Structure I is part of a chain of one or more carbons ("carbon chain") of a positively charged organic group. The carbon atom is directly ether-linked to a glucose monomer of the poly alpha-1,3-glucan or is part of a chain of two or more carbon atoms ether-linked to a glucose monomer of the poly alpha-1,3-glucan. The carbon atom in Structure I may be -CH2-, -CH- (where H is replaced with another group such as a hydroxyl group), or -C- (where both H are replaced).

[0031] The substituted ammonium group may be a "primary ammonium group," a "secondary ammonium group," a "tertiary ammonium group," or a "quaternary ammonium" group, depending on the composition of R2, R3, and R4 in structure I. Quaternary ammonium groups are preferred herein and refer to structure I in which R2, R3, and R4 are, respectively, alkyl, aryl, or cycloalkyl groups (i.e., none of R2, R3, and R4 are hydrogen atoms).

[0032] The quaternary ammonium poly alpha-1,3-glucan ether herein may, for example, comprise a trialkylammonium group (wherein R2, R3, and R4 are each an alkyl group). A trimethylammonium group is an example of a trialkylammonium group, where R2, R3, and R4 are each a methyl group. It will be understood that the fourth member (i.e., R1) designated by "quaternary" in this nomenclature is a chain of one or more carbons of a positively charged organic group that is ether-linked to the glucose monomer of the poly alpha-1,3-glucan.

[0033] An example of a quaternary ammonium poly alpha-1,3-glucan ether compound is trimethylammonium hydroxypropyl poly alpha-1,3-glucan. The positively charged organic group of this ether compound can be represented as Structure II:

[0034] [ka] wherein R2, R3, and R4 are each a methyl group. Structure II is an example of a quaternary ammonium hydroxypropyl group.

[0035] In the group according to structure II, any one of R2, R3, and R4 is C 12 It may be substituted with alkyl, and the remaining R groups may be substituted with methyl groups.

[0036] As used herein, the term "degree of substitution" (Dos) refers to the average number of hydroxyl groups substituted on each monomer unit (glucose) of a poly alpha-1,3-glucan ether compound. Since there are three hydroxyl groups on each monomer unit in poly alpha-1,3-glucan, the degree of substitution in the poly alpha-1,3-glucan ether compound herein can be 3 or less.

[0037] As used herein, the term "molar substitution" (MS) refers to the number of moles of positively charged organic groups per monomer unit of a poly alpha-1,3-glucan ether compound. Alternatively, MS may refer to the average number of moles of etherification agent used to react with each monomer unit in a poly alpha-1,3-glucan (MS can therefore describe the degree of derivatization of the etherification agent). It should be noted that the MS value of a poly alpha-1,3-glucan may not have an upper limit. For example, when a positively charged organic group containing a hydroxyl group (e.g., hydroxyethyl or hydroxypropyl) is etherified to a poly alpha-1,3-glucan, the hydroxyl group of the organic group can undergo further reaction, thereby allowing more positively charged organic groups to be attached to the poly alpha-1,3-glucan.

[0038] The term "crosslink" as used herein refers to a chemical bond, atom, or group of atoms that connects two adjacent atoms in one or more polymer molecules. It should be understood that in a composition that includes crosslinked poly alpha-1,3-glucan ether, there may be crosslinks between at least two poly alpha-1,3-glucan ether molecules (i.e., intermolecular crosslinks), and there may also be intramolecular crosslinks. As used herein, a "crosslinker" is an atom or compound that can generate crosslinks.

[0039] An "aqueous composition" herein refers to a solution or mixture in which the solvent is, for example, at least about 20% by weight water and which contains poly alpha-1,3-glucan and / or poly alpha-1,3-glucan ether compounds. Examples of aqueous compositions herein are aqueous solutions and hydrocolloids.

[0040] The terms "hydrocolloid" and "hydrogel" are used interchangeably herein. Hydrocolloid refers to a colloidal system in which water is the dispersion medium. As used herein, "colloid" refers to a material that is microscopically dispersed throughout another material. Thus, hydrocolloid as used herein may refer to a dispersion, emulsion, mixture, or solution of poly alpha-1,3-glucan and / or one or more poly alpha-1,3-glucan ether compounds in water or an aqueous solution.

[0041] The term "aqueous solution" as used herein refers to a solution in which the solvent is water. The poly alpha-1,3-glucan and / or one or more poly alpha-1,3-glucan ether compounds herein can be dispersed, mixed, and / or dissolved in the aqueous solution. The aqueous solution can function as the dispersion medium of the hydrocolloid herein.

[0042] As used herein, the term "viscosity" refers to a measure of the degree to which an aqueous composition, such as a fluid or hydrocolloid, resists forces tending to cause it to flow. Various units of viscosity that can be used herein include centipoise (cPs) and Pascal seconds (Pa s). A centipoise is one-hundredth of a poise, and 1 poise is 0.100 kg m -1 ·s -1 Thus, as used herein, the terms "viscosity modifier" and "viscosity adjuster" refer to anything that can change / adjust the viscosity of a fluid or aqueous composition. Viscosity is determined according to the procedure provided in the Test Methods section below.

[0043] As used herein, the term "shear thinning behavior" refers to the decrease in viscosity of a hydrocolloid or aqueous solution as the shear rate increases. As used herein, the term "shear thickening behavior" refers to the increase in viscosity of a hydrocolloid or aqueous solution as the shear rate increases. "Shear rate" herein refers to the rate at which a progressive shear deformation is applied to the hydrocolloid or aqueous solution. The shear deformation can be applied rotationally.

[0044] The terms "fabric," "textile," and "cloth" are used interchangeably herein and refer to a woven material having a network of natural and / or man-made fibers. Such fibers may be, for example, yarns or yarns.

[0045] The terms "heavy duty detergent" and "all-purpose detergent" are used interchangeably herein and refer to detergents useful for normal washing of white and colored textiles at any temperature. The terms "light duty detergent" or "fine fabric detergent" are used interchangeably herein and refer to detergents useful for the care of delicate fabrics such as viscose, wool, silk, microfiber, or other fabrics that require special care. "Special care" may include, for example, conditions such as using excess water, low agitation, and / or no bleach.

[0046] The term "adsorption" herein refers to the adhesion of a compound (eg, poly alpha-1,3-glucan ether) to a material surface.

[0047] In this specification, the "molecular weight" of the poly α-1,3-glucan and poly α-1,3-glucan ether compounds refers to the number average molecular weight (M n ) or weight average molecular weight (M wMolecular weight can be expressed as Daltons, grams per mole, DPw (weight average degree of polymerization), or DPn (number average degree of polymerization). Various means for calculating these molecular weight measurements are known in the art, such as high pressure liquid chromatography (HPLC), size exclusion chromatography (SEC), or gel permeation chromatography (GPC). As further described in the Test Methods section below, size exclusion chromatography is used to determine the weight average molecular weight.

[0048] The terms "percent by volume," "volume percent," "volume %," and "v / v %" are used interchangeably herein. The volume percent of a solute in a solution can be determined using the formula: [(volume of solute) / (volume of solution)]×100%.

[0049] The terms "weight percent," "weight percent (wt%)," and "weight-to-weight percent (% w / w)" are used interchangeably herein. Weight percent refers to the percentage of a material by mass when contained in a composition, mixture, or solution.

[0050] The terms "increase," "enhance," and "improve" are used interchangeably herein. These terms refer to a greater amount or activity, such as an amount or activity slightly greater than an original amount or activity, or an amount or activity that is in large excess compared to the original amount or activity, including all amounts or activities in between. Alternatively, these terms may refer to an amount or activity that is, for example, at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 125%, 150%, 175%, or 200% (or any integer between 1% and 200%) greater than the amount or activity compared to which the increased amount or activity is compared.

[0051] Unless otherwise noted, all component or composition concentrations are in terms of the active portion of that component or composition and are exclusive of impurities, e.g., residual solvents or by-products, which may be present in commercial sources of such components or compositions.

[0052] All temperatures herein are in degrees Celsius (° C.) unless otherwise indicated. All measurements herein are made at 20° C. and atmospheric pressure unless otherwise stated.

[0053] In all embodiments of the present disclosure, all percentages are by weight of the total composition unless otherwise specified. All ratios are by weight unless otherwise specified.

[0054] It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification includes every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification includes every narrower numerical range that is included within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

The composition may be selected from a liquid, a solid, or a combination thereof. The composition may be in the form of a liquid fabric improver, a foam / mousse, a dryer sheet, or a pastry tablet / bead.

[0058] Such compositions may be used as laundry pre-treatments, laundry post-treatments, may be added during the rinse or wash cycle of a laundry operation, or even during the drying process. Such compositions may be applied to fabrics between uses of the fabric, such as between wearing of a garment.

[0059] The composition may be in the form of a liquid. The composition may include water. The composition may be aqueous. The composition may be a liquid composition and may include at least 50% water by weight, preferably at least 75% by weight, or even more than 85% by weight, or even more than 90% by weight, or even more than 95% by weight of water.

Such compositions may be preferred, for example for environmental reasons, to minimize the energy required to transport water. Such compositions may be liquid, gel, or solid (including granules or powders, and / or dissolvable sheets or webs).

[0061] The composition may be in the form of a unit dose article, such as a tablet, pouch, sheet, or fibrous article. Such pouches typically include a water-soluble film, e.g., a polyvinyl alcohol water-soluble film, that at least partially encapsulates the composition. Suitable films are available from MonoSol, LLC (Indiana, USA). The composition may be encapsulated in a single compartment pouch or a multi-compartment pouch. A multi-compartment pouch may have at least two, at least three, or at least four compartments. A multi-compartment pouch may include compartments arranged side-by-side and / or stacked. The composition contained in the pouch or its compartments may be liquid, solid (such as a powder), or a combination thereof.

The particles may be used in combination with a detergent composition, for example, simultaneously during a wash cycle or subsequently during a rinse cycle.

[0063] The fabric care composition is applied for 20 seconds. -1 and 21°C, 1 to 1500 centipoise (1 to 1500 mPa * s), or 100 to 1000 centipoise (100 to 1000 mPa * s), or 100 to 500 centipoise (100 to 500 mPa * s), or 100 to 300 centipoise (100 to 300 mPa * s), or 100-200 centipoise (100-200mPa *s), the viscosity being determined according to the Brookfield Test Method provided below.

[0064] The fabric care compositions of the present disclosure may be characterized as having a pH of about 2 to about 12, or about 2 to about 8.5, or about 2 to about 7, or about 2 to about 5. The compositions of the present disclosure, preferably in the form of an aqueous liquid, may have a pH of about 2 to about 4, preferably a pH of about 2 to about 3.7, and more preferably a pH of about 2 to about 3.5. Such pH levels are believed to promote the stability of the quaternary ammonium ester compound. The pH of the composition is measured by dissolving / dispersing the composition in deionized water to form a 10% concentration solution at about 20°C.

[0065] The specific components of the fabric conditioning composition are described in more detail below.

[0066] Poly α-1,3-glucan ether compound The fabric conditioning composition and method of the present disclosure may include a poly alpha-1,3-glucan ether compound.Typically, the poly alpha-1,3-glucan ether compound is a cationic charged poly alpha-1,3-glucan ether compound.Such compounds are generally known to provide viscosity adjusting benefits to certain compositions, but it has been surprisingly found that selecting a specific molecular weight and / or degree of substitution of a cationic poly alpha-1,3-glucan ether compound can provide improved performance benefits to certain fabric conditioning compositions, especially those that further include a depositable benefit agent.

[0067] The fabric conditioning composition of the present disclosure may comprise from about 0.01% to about 3%, or from about 0.05% to about 2.5%, or from about 0.1% to about 2%, or from about 0.2% to about 1.5%, or from about 0.2% to about 1%, or from about 0.2% to about 0.75%, or from about 0.2% to about 0.5% poly alpha-1,3-glucan ether compound by weight of the fabric conditioning composition.

[0068] The poly alpha-1,3-glucan ether compound can include from about 425 to about 1200 structural units having the following structure:

[0069] [ka] (wherein each R is independently H or a positively charged organic group). The poly α-1,3-glucan ether compound may contain about 500 to about 1100, or about 600 to about 1050, or about 700 to about 1000, or about 700 to about 900, or about 700 to about 800 repetitions of the indicated structural units. As shown below, it is desirable to appropriately select the number of structural units (and thus the molecular weight) to provide an effective conditioning composition. Each R is independently H or a positively charged organic group, and the positively charged organic group may contain a substituted ammonium group, preferably a quaternary ammonium group, more preferably a trialkylammonium group, and even more preferably a trimethylammonium group. The poly α-1,3-glucan ether compound may contain other structural units, including structural units that function as branch points, but it is preferable that there is little to no branching.

[0070] The poly alpha-1,3-glucan ether compound may be represented by the following structure:

[0071] [ka]

[0072] With respect to this structural formula, n can be from about 425 to about 1200, and each R in the compound can be independently H or a positively charged organic group. Additionally, the poly α-1,3-glucan ether compound can have a degree of substitution of from about 0.15 to about 0.8.

[0073] The degree of substitution (DoS) of the poly alpha-1,3-glucan ether compounds disclosed herein may be about 0.15 to about 0.8, or about 0.3 to about 0.7, or about 0.3 to about 0.6, or about 0.4 to about 0.6, or about 0.4 to about 0.5. If the glucan ether compound is intended to be used in a through-the-wash application (e.g., as part of or in combination with a laundry detergent), the DoS may be about 0.15 to about 0.6. If the glucan ether compound is intended to be used in a through-the-rinse application (e.g., as part of a liquid fabric strengthener), the DoS may be about 0.3 to about 0.8. The poly alpha-1,3-glucan ether compounds herein have a degree of substitution of about 0.15 to about 0.8, and being ethers, one skilled in the art will understand that the R groups of the compounds cannot be hydrogen only.

[0074] The percentage of glycosidic bonds between glucose monomer units of the poly alpha-1,3-glucan ether compounds herein that are alpha-1,3 is at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% (or any integer between 50% and 100%). Thus, in such embodiments, the compounds have less than about 50%, 40%, 30%, 20%, 10%, 5%, 4%, 3%, 2%, 1%, or 0% (or any integer between 0% and 50%) of glycosidic bonds that are not alpha-1,3.

[0075] The backbone of the poly alpha-1,3-glucan ether compound herein may preferably be substantially linear / unbranched.For example, the compound may have no branch points or may have less than about 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% branch points as a percentage of glycosidic bonds in the polymer.Examples of branch points include alpha-1,6 branch points.It is believed that having a relatively small number of branch points can provide a relatively large amount of water-soluble polymer, which can facilitate ease of formulation.

[0076] For the above poly alpha-1,3-glucan ether compounds, the index n may be about 425 to about 1200, or about 500 to about 1100, or about 600 to about 1050, or about 600 to about 1000, or about 700 to about 1000, or about 700 to about 900, or about 700 to about 800. Appropriate selection of the molecular size (affecting the weight average molecular weight) is believed to be important to facilitate improved performance of conditioning actives and conditioning compounds containing same. For example, if the molecular size is too small, the conditioning active may not adhere properly, and if the molecular size is too large, the viscosity of the composition may be adversely affected, for example, by increasing the viscosity.

[0077] The molecular weight of the poly α-1,3-glucan ether compound in this specification is the weight average molecular weight (M W ). Weight average molecular weight is determined by size exclusion chromatography (SEC) as described in more detail in the Test Methods section. The poly alpha-1,3-glucan ether compounds herein may be characterized by a weight average molecular weight of about 90 kilodaltons to about 350 kilodaltons, or about 90 kilodaltons to about 300 kilodaltons, or about 90 kilodaltons to about 260 kilodaltons, or about 90 to about 240 kilodaltons, or about 95 to about 200 kilodaltons, or about 100 to about 175 kilodaltons, or about 100 to about 150 kilodaltons (which is most preferred).

[0078] The poly alpha-1,3-glucan ether compounds herein may be derived from a polysaccharide backbone characterized by a weight average molecular weight, determined before substitution, of about 90 kilodaltons to about 190 kilodaltons. For a linear polymer of about 120 kilodaltons, the number of repeat units is 740. The polydispersity may range from 1 to about 5, more preferably from 1 to about 3.

[0079] Each R group in the formula of the poly alpha-1,3-glucan ether compounds herein can be independently H or a positively charged organic group. As defined above, a positively charged organic group comprises a chain of one or more carbons having one or more hydrogens replaced with another atom or functional group, where one or more of the replacements is with a positively charged group.

[0080] The positively charged group may be, for example, a substituted ammonium group. Examples of substituted ammonium groups are primary, secondary, tertiary, and quaternary ammonium groups. Structure I shows a primary, secondary, tertiary, or quaternary ammonium group, depending on the composition of R2, R3, and R4 in Structure I, as described above. Each of R2, R3, and R4 in Structure I independently represents a hydrogen atom, or an alkyl, aryl, cycloalkyl, aralkyl, or alkaryl group. Alternatively, each of R2, R3, and R4 may independently represent a hydrogen atom or an alkyl group. An alkyl group herein may be, for example, a methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, or decyl group. When two or three of R2, R3, and R4 are alkyl groups, they may be the same or different alkyl groups.

[0081] Quaternary ammonium poly alpha-1,3-glucan ether compounds are preferred. The "quaternary ammonium poly alpha-1,3-glucan ether compounds" herein may include, for example, a positively charged organic group having a trialkylammonium group. In this example, the positively charged organic group is structure I, in which R2, R3 and R4 are each an alkyl group. A non-limiting example of such a positively charged organic group is represented by structure II, in which R2, R3 and R4 are each an alkyl group. Examples of quaternary ammonium poly alpha-1,3-glucan ether compounds can be briefly represented as trialkylammonium poly alpha-1,3-glucan ethers (e.g., trimethyl, triethyl, tripropyl, tributyl, tripentyl, trihexyl, triheptyl, trioctyl, trinonyl or tridecyl-ammonium poly alpha-1,3-glucan ethers). It will be understood that the fourth member (i.e., R1) designated by "quaternary" in the above nomenclature is a chain of one or more carbons of positively charged organic groups ether-linked to the glucose monomers of the poly alpha-1,3-glucan.

[0082] Although quaternary compounds are preferred, compositions of the present disclosure may contain primary, secondary, and / or tertiary ammonium poly alpha-1,3-glucan ether compounds, for example as impurities and / or partially reacted reaction products.

[0083] Further non-limiting examples of substituted ammonium groups that can function as positively charged groups herein are represented by structure I, where R2, R3, and R4 each independently represent a hydrogen atom, an alkyl group such as a methyl, ethyl, or propyl group, an aryl group such as a phenyl or naphthyl group, an aralkyl group such as a benzyl group, an alkaryl group, or a cycloalkyl group. Each of R2, R3, and R4 can further include, for example, an amino group or a hydroxyl group.

[0084] The nitrogen atom in the substituted ammonium group represented by structure I, when included in a positively charged organic group, is linked to one or more carbon chains. This one or more carbon chains ("carbon chains") are ether-linked to the glucose monomers of poly alpha-1,3-glucan, and can have one or more substitutions in addition to the substitution by the nitrogen atom of the substituted ammonium group. For example, the carbon chains herein can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 carbons. For example, the carbon chain of structure II is 3 carbon atoms long.

[0085] When the carbon chain of the positively charged organic group has substitutions in addition to the substitution by the positively charged group, such additional substitutions can be one or more hydroxyl groups, oxygen atoms (thereby forming an aldehyde or ketone group), alkyl groups (e.g., methyl, ethyl, propyl, butyl), and / or additional positively charged groups. The positively charged group is typically linked to the terminal carbon atom of the carbon chain. The carbon chain can include one or more substitutions including a hydroxyl group, preferably a hydroxyalkyl group, more preferably a hydroxypropyl group.

[0086] The poly alpha-1,3-glucan ether compounds in certain embodiments disclosed herein may contain one type of positively charged organic group as the R group. For example, one or more of the positively charged organic groups ether-linked to the glucose monomers of the poly alpha-1,3-glucan may be a trimethylammonium hydroxypropyl group (structure II), and thus the R groups in this embodiment will be independently hydrogen and a trimethylammonium hydroxypropyl group.

[0087] Alternatively, the poly alpha-1,3-glucan ether compounds disclosed herein may contain two or more different positively charged organic groups as R groups.

[0088] The poly alpha-1,3-glucan ether compounds herein may, for example, comprise at least one non-ionic organic group and at least one anionic group. As another example, the poly alpha-1,3-glucan ether compounds herein may comprise at least one non-ionic organic group and at least one positively charged organic group.

[0089] The poly alpha-1,3 glucan and / or poly alpha-1,3-glucan ether herein is mostly or completely stable (resistant) to degradation by cellulase enzymes. For example, the degradation rate of the poly alpha-1,3 glucan and / or poly alpha-1,3-glucan ether compound by one or more cellulases is less than 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1%, or 0%. Such degradation rate can be determined, for example, by comparing the molecular weight of the polymer before and after treatment with cellulase for a period of time (e.g., 24 hours). Advantageously, such compounds can be co-formulated with cellulase, used simultaneously with cellulase-containing products, or used sequentially with products where residual cellulase may remain on surfaces and / or in aqueous environments.

[0090] The poly alpha-1,3-glucan ethers disclosed herein comprise a poly alpha-1,3-glucan backbone randomly substituted with ether modifications along the polysaccharide backbone, such that the polysaccharide backbone comprises unsubstituted and substituted alpha-D-glucose rings. In embodiments where branches are present, the alpha-D-glucose rings of the branches may also be randomly substituted with ether modification groups. As used herein, the term "randomly substituted" means that the substituents on the glucose rings in the randomly substituted polysaccharide are present in a non-repeated or random manner. That is, the substitution on the substituted glucose ring may be the same or different from the substitution on a second substituted glucose ring in the polysaccharide [i.e., the substituents on different atoms of the glucose ring in the polysaccharide (which may be the same or different)], such that the overall substitution on the polymer does not have a pattern. Furthermore, the substituted glucose rings are present randomly within the polysaccharide (i.e., there is no pattern of substituted and unsubstituted glucose rings within the polysaccharide).

[0091] Depending on the reaction conditions, the poly alpha-1,3-glucan ether compounds disclosed herein may include a poly alpha-1,3-glucan backbone that is "non-randomly" substituted with ether modifying groups along the polysaccharide backbone. In situations where branches are present, the alpha-D-glucose rings of the branches may disproportionately contain more substitutions than the backbone glucose monomer units linked via alpha-1,3-glycosidic bonds. It is also possible that, under certain reaction conditions, modifications may exist in blocks within the polysaccharide.

[0092] Depending on the reaction conditions, it is also possible that the glucose carbon positions 1, 2, 3, 4, and 6 of the poly alpha-1,3-glucan backbone are "disproportionately" substituted. For example, the -OH group at carbon position 6 may be more reactive under certain reaction conditions because it is a primary hydroxyl group and may be in a less sterically hindered environment, and therefore more substitution may occur at this position. Other reaction conditions may allow the -OH group at carbon positions 1, 2, 3, or 4 to be more reactive.

[0093] Depositable Conditioning Actives The fabric conditioning composition may further comprise a depositable conditioning active, which is an ingredient intended to be deposited on a target surface, typically a fabric, with the intent that the ingredient will remain on the target surface for at least a period of time after a treatment cycle, for example after the garment has been washed and / or dried.

[0094] The depositable conditioning active may be a softening active, a freshness active, or a mixture thereof. It may be preferred that the depositable conditioning active is useful in the context of a fabric enhancing composition, preferably a liquid fabric enhancing composition.

[0095] The depositable active may be present at a level of about 0.1% to about 35%, or about 0.1% to about 25% by weight of the fabric conditioning composition. When the depositable active is a softening active, the softening active may be present at a level of about 2% to about 35%, or about 2% to about 20%, or about 2% to about 12%, or about 2% to about 8%. When the depositable active is a freshness active, the freshness active may be present at a level of about 0.1% to about 10%, or about 0.2% to about 5%, or about 0.3% to about 3%.

[0096] Softening active substance The fabric conditioning composition of the present disclosure may include a softening active. The softening active may provide softness, wrinkle prevention, static prevention, conditioning, stretch prevention, color, and / or appearance benefits to the target fabric. The softening active may be selected from the group consisting of quaternary ammonium ester compounds, silicones, non-ester quaternary ammonium compounds, amines, fatty acid esters, sucrose esters, silicones, dispersible polyolefins, polysaccharides, fatty acids, softening or conditioning oils, polymer latexes, glyceride copolymers, or combinations thereof.

[0097] The composition may contain a quaternary ammonium ester compound, a silicone, or a combination of a plurality of pairs thereof, preferably a combination of a plurality of pairs thereof. The total amount of the quaternary ammonium ester compound and the silicone may be about 5% by weight to about 70% by weight, or about 6% by weight to about 50% by weight, or about 7% by weight to about 40% by weight, or about 10% by weight to about 30% by weight, or about 15% by weight to about 25% by weight of the composition. The composition may contain the quaternary ammonium ester compound and the silicone in a weight ratio of about 1:10 to about 10:1, or about 1:5 to about 5:1, or about 1:3 to about 1:3, or about 1:2 to about 2:1, or about 1:1.5 to about 1.5:1, or about 1:1.

[0098] The compositions of the present disclosure may include a quaternary ammonium ester compound as a softening active. The quaternary ammonium ester compound (sometimes referred to as an "ester quat") may be present at a concentration of about 2% to about 40%, or about 3% to about 25%, preferably 4% to 18%, more preferably 5% to 15% by weight of the composition. Preferably, the iodine value (see Methods) of the parent fatty acid from which the quaternary ammonium fabric compound is formed may be about 0 to about 90, or about 10 to about 70, or about 15 to about 50, or about 18 to about 30. The iodine value may be about 25 to 50, preferably 30 to 48, more preferably 32 to 45. Without wishing to be bound by theory, when the parent fatty acid from which the quaternary ammonium compound is formed is at least partially unsaturated, a lower melting point is obtained which facilitates the processability of the softening active. In particular, doubly unsaturated fatty acids allow the softening active to be easily processed. In preferred liquid fabric softening compositions, the parent fatty acid from which the quaternary ammonium conditioning active is formed contains 2.0% to 20.0%, preferably 3.0% to 15.0%, more preferably 4.0% to 15.0% doubly unsaturated C18 chains ("C18:2") by weight of the total fatty acid chains (see Methods section). On the other hand, very high concentrations of unsaturated fatty acid chains should be avoided in order to minimize malodor formation as a result of oxidation of the fabric softener composition over time.

[0099] The quaternary ammonium ester compound may be present at a concentration of greater than 0% to about 30%, about 1% to about 25%, about 3% to about 20%, about 4.0% to 18%, more preferably 4.5% to 15%, even more preferably 5.0% to 12% by weight of the composition. The level of the quaternary ammonium ester compound may depend on the desired concentration of total fabric conditioning actives in the composition (diluted or concentrated composition) and the presence or absence of other softening actives. However, typically, fabric treatment compositions with higher softening active levels have a higher risk of viscosity increasing over time. On the other hand, at very high softening active levels, the viscosity can no longer be adequately controlled and the product becomes unsuitable for use.

[0100] Suitable quaternary ammonium ester compounds include, but are not limited to, materials selected from the group consisting of monoester quats, diester quats, and triester quats, and mixtures thereof. Preferably, based on the total quaternary ammonium ester compounds, the concentration of the monoester quat is 2.0% to 40.0% by weight, the concentration of the diester quat is 40.0% to 98.0% by weight, and the concentration of the triester quat is 0.0% to 25.0% by weight.

[0101] The quaternary ammonium ester compound is the following compound: {R 2 (4-m) -N+-[XYR 1 ] m}A - (In the formula, m is 1, 2, or 3, provided that each value of m is the same; Each R 1 are independently a hydrocarbyl group or a branched hydrocarbyl group, preferably R 1 is linear, more preferably R 1 is a partially unsaturated linear alkyl chain, Each R 2are independently a C1 to C3 alkyl group or a hydroxyalkyl group, preferably R 2 is selected from methyl, ethyl, propyl, hydroxyethyl, 2-hydroxypropyl, 1-methyl-2-hydroxyethyl, poly(C2-C3 alkoxy), polyethoxy, and benzyl; each X is independently -(CH2)n-, -CH2-CH(CH3)-, or -CH-(CH3)-CH2-; each n is independently 1, 2, 3, or 4, preferably each n is 2; each Y is independently -O-(O)C- or -C(O)-O-; A- is independently selected from the group consisting of chloride, methyl sulfate, and ethyl sulfate, and preferably A - is selected from the group consisting of chloride and methyl sulfate, more preferably A- is methyl sulfate; However, when Y is -O-(O)C-, each R 1 The sum of carbons in is from 13 to 21, preferably from 13 to 19. Preferably, X is -CH2-CH(CH3)- or -CH-(CH3)-CH2- to improve the hydrolytic stability of the quaternary ammonium ester compound, which in turn further improves the stability of the fabric treatment composition.

[0102] Examples of suitable quaternary ammonium ester compounds are commercially available from Evonik under the trade names Rewoquat WE18 and / or Rewoquat WE20, and / or from Stepan under the trade names Stepantex GA90, Stepantex VK90, and / or Stepantex VL90A.

[0103] The fabric conditioning compositions of the present disclosure may include silicone as a softening active. Suitable concentrations of silicone may include from about 0.1% to about 70%, or from about 0.3% to about 40%, or from about 0.5% to about 30%, or from about 1% to about 20%, by weight of the composition.

[0104] Useful silicones can be any suitable silicone-containing compound. Silicone polymers can be selected from the group consisting of cyclic silicones, polydimethylsiloxanes, aminosilicones, cationic silicones, silicone polyethers, silicone resins, silicone urethanes, and mixtures thereof. Silicones can include polydialkylsilicones, such as polydimethylsilicones (polydimethylsiloxanes, or "PDMS"), or derivatives thereof. Silicones can include amino-functional silicones, amino-polyether silicones, alkyloxylated silicones, cationic silicones, ethoxylated silicones, propoxylated silicones, ethoxylated / propoxylated silicones, quaternary silicones, or combinations thereof. Silicones can include polydimethylsilicones, aminosilicones, or combinations thereof, preferably aminosilicones.

[0105] The silicone may include a random or block organosilicone polymer. The silicone may be provided as an emulsion.

[0106] Silicones may be characterized by relatively high molecular weight. A suitable method for describing the molecular weight of silicones is to describe their viscosity. High molecular weight silicones may have a viscosity of about 10 cSt to about 3,000,000 cSt, or about 100 cSt to about 1,000,000 cSt, or about 1,000 cSt to about 600,000 cSt, or even about 6,000 cSt to about 300,000 cSt.

[0107] The composition may include a glyceride copolymer. The glyceride copolymer may be derived from a natural oil. Examples of natural oils include, but are not limited to, vegetable oils, algae oils, fish oils, animal fats, tall oil, derivatives of these oils, any combination of these oils, and the like.

The glyceride copolymer can be a metathesized unsaturated polyol ester.

[0108] Freshness Actives The fabric conditioning composition of the present disclosure may include a freshness active. The freshness active may provide a fragrance (e.g., perfume) benefit and / or a malodor reduction or malodor control benefit. The freshness active may deliver the intended benefit at one or more consumer contact points, including in the neat product, in the treatment solution, on wet fabrics, on dry fabrics, or on rubbed fabrics. The freshness active may be selected from a fragrance active, a malodor control agent, or a combination thereof.

[0109] The freshness active may be a fragrance active. The perfume active may be selected from a free perfume, a perfume delivery system, a pro-perfume, or a mixture thereof.

[0110] Fragrance actives may include one or more perfume raw materials. The term "perfume raw material" (or "PRM"), as used herein, refers to a compound that has a molecular weight of at least about 100 g / mole and is useful for imparting odor, fragrance, essence, or scent, alone or together with other perfume raw materials. Typical PRMs include, among others, alcohols, ketones, aldehydes, esters, ethers, nitrites, and alkenes such as terpenes. Lists of common PRMs can be found in various reference sources, such as, for example, "Perfume and Flavor Chemicals" Volumes I and II; Steffen Arctander Allured Pub.Co. (1994) and "Perfumes: Art, Science and Technology", Miller, PM and Lamparsky, D., Blackie Academic and Professional (1994). The compositions may comprise from about 0.05% to about 20%, or from about 0.1% to about 10%, or from about 0.1% to about 5%, by weight of the composition, of a fragrance raw material, and the level of freshness actives may be selected accordingly.

[0111] Fragrance actives may include, for example, free perfume, which is a perfume raw material that is not encapsulated or chemically bound to other ingredients. Free perfume may be added to the base composition neat or as an emulsion and / or in combination with a solubilizing agent, which may facilitate proper dispersion or stability in the composition.

[0112] Fragrance actives may include perfume delivery systems.Suitable perfume delivery systems, the manufacturing method of specific perfume delivery systems, and the use of such perfume delivery systems are disclosed in US Patent Application Publication No. 2007 / 0275866(A1).Perfume delivery systems may include Polymer Assisted Delivery (PAD) (including matrix systems or reservoir systems such as inclusion bodies), Molecule-Assisted Delivery (MAD), Amine-Assisted Delivery (AAD), Cyclodextrin Delivery System (CD), Starch Encapsulated Accords (SEA), Inorganic Carrier Delivery System (ZIC), or mixtures thereof.

[0113] The fabric conditioning composition of the present disclosure comprises an encapsulant as a perfume delivery system. Typically, there is more than one encapsulant, so the composition may be described as comprising a plurality of encapsulants or a population of encapsulants.

[0114] The composition may comprise from about 0.05% to about 20%, or from about 0.05% to about 10%, or from about 0.1% to about 5%, or from about 0.2% to about 2% of the encapsulating agent by weight of the composition. The composition may comprise an amount of encapsulating agent sufficient to provide the composition with from about 0.05% to about 10%, or from about 0.1% to about 5%, or from about 0.1% to about 2% of perfume by weight of the composition. As discussed herein, the amount or weight percent of the encapsulating agent refers to the combined shell material and core material.

[0115] The encapsulating agent may have a volume weight median encapsulating agent size of about 0.5 micrometers to about 100 micrometers, alternatively 10 to 100 micrometers, preferably about 1 micrometer to about 60 micrometers, alternatively 10 micrometers to 50 micrometers, alternatively 20 micrometers to 45 micrometers, or alternatively 20 micrometers to 60 micrometers.

[0116] The encapsulation typically has a wall (or shell) that at least partially surrounds a core, which may include a perfume raw material and, optionally, a partitioning modifier, such as isopropyl myristate or other suitable material.

[0117] The wall may comprise a material selected from the group consisting of polyethylene, polyamide, polystyrene, polyisoprene, polycarbonate, polyester, polyacrylate, acrylic, aminoplast, polyolefin, polysaccharides such as alginate and / or chitosan, gelatin, shellac, epoxy resins, vinyl polymers, water insoluble inorganic materials, silicones, and mixtures thereof. The wall material may comprise a material selected from aminoplasts, polyurethanes, polyureas, polyacrylates, or mixtures thereof.

[0118] The outer wall of the inclusion may have a coating. Certain coatings may improve the adhesion of the inclusion onto a target surface, such as a fabric. The coating may include an efficacy polymer. The coating may include a cationic efficiency polymer. The cationic polymer may be selected from the group consisting of polysaccharides, cationically modified starches, cationically modified guars, polysiloxanes, polydiallyldimethylammonium halides, copolymers of polydiallyldimethylammonium chloride and vinylpyrrolidone, acrylamides, imidazoles, imidazolinium halides, imidazolium halides, polyvinylamines, polyvinylformamides, polyallylamines, copolymers thereof, and mixtures thereof. The coating may include a polymer selected from the group consisting of polysaccharides (such as chitosan), polyvinylamines, polyvinylformamides, polyallylamines, copolymers thereof, and mixtures thereof.

[0119] The encapsulation may include a wall comprising an aminoplast material and a coating comprising polyvinylformamide.The encapsulation may include a wall comprising a polyacrylate material and a coating comprising chitosan.

[0120] The composition may be a fabric enhancer composition comprising perfume encapsulates, preferably when the composition is liquid. The composition may be a detergent composition, preferably a liquid detergent composition (optionally contained in a water-soluble pouch), comprising perfume encapsulates, about 5% to about 50%, preferably about 8% to about 40%, of an anionic surfactant, preferably selected from linear alkyl benzene sulfonates, alkyl sulfates, and / or alkoxylated alkyl sulfates such as AES, and a cationic poly alpha-1,3-glucan ether compound according to the present disclosure.

[0121] The fragrance active may include a pro-perfume, which typically includes a perfume raw material and a substantive or soluble component, which are typically bound, complexed, or otherwise coupled together. Over time or upon other triggering stimuli (e.g., contact with water, change in pH, or elevated temperature), the PRM and the component are separated, resulting in a sustained release of the PRM. By selecting the appropriate substantive or soluble component, the formulation can control the solubility of the pro-perfume in water, the degree of substantivity of the pro-perfume to the fabric, or the bulk properties of the material.

[0122] For example, once the washing process is complete and the pro-perfume has been suitably delivered to the fabrics, the pro-perfume will begin to release the perfume ingredients and this release of the materials will continue so that the fabrics smell "fresh" and "clean" for longer.

[0123] Suitable pro-perfumes may include dimethoxybenzoin derivatives and / or amine reaction products.

[0124] The freshness active may be a malodor control agent. The malodor control agent may include an oligoamine. Certain oligoamines may contribute to inhibiting the decomposition of certain compounds that may otherwise oxidize to malodorous compounds.

The diethylenetriamine may be selected from diethylenetriamine (DETA), 4-methyldiethylenetriamine (4-MeDETA), 1,1,4,7,7-pentamethyldiethylenetriamine (M5-DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), N,N'-bis(3-aminopropyl)ethylenediamine, and mixtures thereof, even more preferably diethylenetriamine (DETA), 4-methyldiethylenetriamine (4-MeDETA), N,N'-bis(3-aminopropyl)ethylenediamine, and mixtures thereof, and most preferably diethylenetriamine (DETA). DETA may be most preferred due to its low molecular weight and / or relatively low manufacturing costs.

[0142] Methods for Making Fabric Conditioning Compositions The present disclosure relates to a method of making any of the compositions described herein. The method of making a fabric conditioning composition may include combining a poly alpha-1,3-glucan ether compound described herein with a fabric conditioning active described herein.

[0143] The fabric conditioning composition of the present disclosure may be formulated into any suitable form and prepared by any method selected by the formulator.Poly alpha-1,3-glucan ether compound, fabric conditioning active, and / or auxiliary materials may be combined in a batch process, a circulation loop process, and / or an in-line mixing process.Apparatus suitable for use in the methods disclosed herein may include continuous stirred tank reactors, homogenizers, turbine agitators, recirculation pumps, paddle mixers, plow shear mixers, ribbon blenders, vertical shaft granulators and drum mixers (both batch and, if available, in a continuous process configuration), spray dryers, and extruders.

[0144] It may be desirable to provide the poly alpha-1,3-glucan ether compound as a polymer premix. The premix may comprise, consist essentially of, or consist of the poly alpha-1,3-glucan ether compound (e.g., 7.5% by weight) and water. The glucan polymer may be present in the premix at a level of about 5% to about 20% by weight of the premix, preferably about 5% to about 10% by weight. The glucan polymer and water may be present in the polymer at a polymer:water weight ratio of about 5:95 to 20:80, or about 5:95 to about 10:90, or about 7.5:92.5. To optimize the polymer premix, the polymer may be prepared using controlled mixing, shear, and time to ensure consistency in the size and shape of the resulting particles, as well as to fully hydrate the glucan polymer and control the gel phase. Once hydration is complete, the polymer premix may be remixed (e.g., with an electric roller or overhead mixer) to ensure uniform flow in case of non-uniform gel formation prior to addition to the base product formulation. Use of a consistent protocol reduces variability in formulation stability and further minimizes inconsistent performance that can result from varying concentrations of polymer premix throughout the finished product.

[0145] The fabric conditioning composition may be encapsulated in a water-soluble film according to known methods to form a unit dose article.

[0146] The fabric conditioning composition may be dispensed into an aerosol or other spray container in accordance with known methods.

[0147] Methods of Using Fabric Conditioning Compositions The present disclosure further relates to methods of using the fabric conditioning compositions. For example, the present disclosure relates to methods of treating fabrics with the compositions according to the present disclosure. Such methods may provide conditioning and / or freshening benefits.

[0148] The method may include contacting a fabric with the fabric conditioning composition of the present disclosure. The composition may be in neat form or may be diluted with a liquid, such as a washing or rinsing liquid. The composition may be diluted with water before, during, or after contact with the surface or article. The fabric may be optionally washed and / or rinsed before and / or after the contacting step. The composition may be applied directly onto the fabric or may be dispensed into a dispensing bin or drum of an automatic washing machine.

[0151] The liquid containing the disclosed composition may have a pH of about 3 to about 11.5. When diluted, such compositions are typically used at a concentration of about 500 ppm to about 15,000 ppm in solution. When the cleaning solvent is water, the temperature of the water typically ranges from about 5° C. to about 90° C., and the water to fabric ratio may typically be about 1:1 to about 30:1.

[0152] The fabric may be contacted with an anionic surfactant, optionally in the presence of water, prior to contacting with the conditioning composition. The fabric may contain residual anionic surfactant from the washing process. The source of the anionic surfactant may be a detergent composition, such as a heavy-duty liquid laundry detergent, a water-soluble pouch containing the detergent composition, or a powder laundry detergent. The detergent composition may further comprise a suitable detergent adjuvant. For example, the detergent composition may further comprise a cellulase enzyme, a fatty acid and / or a salt thereof, or a mixture thereof.

[0153] The anionic surfactant and / or a source thereof (e.g., a detergent composition) may be diluted with water in a container, such as the drum of an automatic washing machine, to form a wash liquor, which may be contacted with the fabrics. The method may further include removing the wash liquor from the container after contacting the fabrics, but before the fabrics are contacted with the conditioning composition.

[0154] The conditioning composition may optionally be diluted with water in a vessel, such as an automatic washing machine, to create a rinse liquor. The rinse liquor may contain anionic surfactants and / or cellulase enzymes that may remain or be carried over from the wash cycle. The rinse liquor may be removed from the vessel. The fabrics may be dried by any suitable method, such as, for example, in an automatic dryer or by line drying.

[0155] The water that is part of the wash liquor and / or rinse liquor may be characterized by a particular hardness. For example, the water may be characterized by having a hardness of less than 12 gpg, or less than 10 gpg. It is believed that lower levels of hardness may result in better performance compared to processes that result in higher levels of hardness.

[0160] To determine the molar substitution of poly α-1,3-glucan ether derivatives 1 H nuclear magnetic resonance (NMR) method Approximately 30 mg of poly alpha-1,3-glucan ether derivative is weighed into a vial on an analytical balance. The vial is removed from the balance and 1.0 mL of deuterium oxide is added to the vial. A magnetic stir bar is added to the vial and the mixture is stirred to suspend the solid. 1.0 mL of deuterated sulfuric acid (50% v / v in D2O) is then added to the vial and the mixture is heated at 90°C for 1 hour to depolymerize and solubilize the polymer. The solution is cooled to room temperature and then a 0.8 mL portion of the solution is transferred to a 5 mm NMR tube using a glass pipette. Quantitative analysis is performed using an Agilent VNMRS 400 MHz NMR spectrometer equipped with a 5 mm Autoswitchable Quad probe. 1 H NMR spectra are acquired using a 6410.3 Hz spectral window, an acquisition time of 3.744 seconds, an interpulse delay of 10 seconds, and 64 pulses at a spectral frequency of 399.945 MHz. Time domain data are transformed using an exponential multiplication of 0.50 Hz.

The software package used for data reduction is Astra version 6 from Wyatt (triple detection method with column calibration).

[0162] Homogenization Homogenization is performed using an IKA ULTRA TURRAX T25 digital homogenizer (IKA, Wilmington, NC).

[0163] Fabric preparation To evaluate the performance of the conditioning compositions and / or polymers contained therein, fabrics are prepared / treated according to the following method.

[0164] A. Equipment and Materials The fabrics are evaluated using a Kenmore FS 600 and / or 80 series washing machine. The washing machine is set as follows: wash / rinse temperature 32°C / 15°C, hardness 6 gpg, standard cycle, and medium wash load (64 liters). The fabric bolster consists of 2.5 kilograms of clean fabric made of 100% cotton. Test swatches were included in the bolster and included 100% cotton Euro Touch terry towels (purchased from Standard Textile, Inc. Cincinnati, Ohio).

[0165] B. Bleaching and desizing Prior to treatment with any test product, the fabric blocks are decolorized according to the Fabric Preparation - Stripping and Desizing Procedure before conducting the test.

[0166] The fabric preparation - bleaching and desizing procedure involves washing a clean mass of fabric (2.5 kg of fabric containing 100% cotton) including a swatch of 100% cotton Euro Touch terry towels for five consecutive wash cycles followed by a dry cycle. The swatch fabric and the clean mass of fabric are bleached / desized using AATCC (American Association of Textile Chemists and Colorists) High Efficiency (HE) liquid detergent (1x recommended dose per wash cycle). Washing conditions are as follows: Kenmore FS 600 and / or 80 series washing machine (or equivalent), wash / rinse temperature 48°C / 48°C, water hardness equal to 0 gpg, standard wash cycle, and medium wash load (64 liters). Dryer timer is set for 55 minutes on the cotton / high / timed dry setting.

[0167] C. Testing Process After the washer is at least half full, add Tide Free liquid detergent (1x recommended dose) below the surface of the water. When the water flow stops and the washer begins to spin, add the clean fabric blocks. When the washer is nearly full of rinse water and before it begins to agitate, slowly add the fabric care test composition (e.g., liquid conditioning composition) (1x dose), ensuring that the fabric care test composition does not come into direct contact with the test swatch or fabric block. Once the wash / rinse cycle is complete, transfer each wet fabric block to its corresponding dryer. The dryer used is a Maytag commercial series (or equivalent) electric dryer with the timer set for 55 minutes on the cotton / high heat / timed dry setting. This process is repeated for a total of three complete wash-dry cycles. After the third drying cycle, when the dryer is stopped, remove 12 terry towels from each fabric block to analyze for active deposition. The fabrics are then placed in a constant temperature / relative humidity controlled scoring room (21° C., 50% relative humidity) for 12-24 hours and then scored for softness and / or active deposition.

[0168] Secant coefficient Instron method Secant modulus is measured using a tensile and compression testing instrument such as an Instron Model 5565 (Instron Corp., Norwood, Massachusetts, USA). The instrument is configured for the fabric by selecting the following settings: mode is Tensile Extension; wave shape is Triangle; maximum strain is 10% for 479 Sanforized and 35% for 7422 Knit; speed is 0.83 mm / sec for 479 Sanforized and 2.5 mm / sec for 7422 Knit; number of cycles is 4; hold time is 15 seconds between cycles. 1. Using scissors, cut the entire sewn edge lengthwise on one side of each swatch, carefully removing the threads without stressing the fabric until an even edge is obtained. 2. Place the fabric press mold and cut strips 1 inch wide and at least 4 inches long parallel to the even edges and cut lengthwise. 3. Cut three strips of woven test fabric 479 sanforized 100% cotton or knitted test fabric 7422 50:50 polycotton from three separate swatches per treatment. Condition the fabrics in a constant temperature (70°F) and humidity (50% RH) room for at least 6 hours prior to analysis. 4. Clamp the top and then bottom of the fabric strip within the 2.54 cm jaws of the tensile testing apparatus, setting a 2.54 cm gap and applying a small amount of force (0.0.05 N to 0.2 N) to the sample. 5. During the hold cycle, release the bottom fixation of the sample, re-fixture it, apply a force of 0.05 N to 0.2 N on the sample, and remove the slack by applying the same force again. 6. Once the four hysteresis cycles are completed for a sample, the secant modulus is reported in megapascals (MPa). The final result is the average of the individual cycle 4 modulus results from all test strips for a given treatment on a given fabric type. The reported secant modulus is calculated at the maximum strain for each fabric type.

[0169] Brookfield Viscosity Measurement Brookfield viscosity is measured using a Brookfield DV-E Viscometer. The liquid is placed in a glass bottle, where the width of the glass bottle is about 5.5-6.5 cm, and the height of the glass bottle is about 9-11 cm. For viscosities below 500 cPs, spindle LV2 at 60 RPM is used, and for viscosities between 500-2,000 cPs, spindle LV3 at 60 RPM is used. The test is performed according to the instrument's instructions. Initial Brookfield viscosity is defined as the Brookfield viscosity measured within 24 hours of preparation of the subject composition.

[0170] Method for determining the iodine value of quaternary ammonium ester compounds The iodine value of the quaternary ammonium ester fabric compounds is the iodine value of the parent fatty acid that forms the fabric conditioning active and is defined as the number of grams of iodine that will react with 100 grams of the parent fatty acid that forms the fabric conditioning active.

[0171] First, the quaternary ammonium ester compound is hydrolyzed according to the following protocol: 25 g of the fabric treatment composition is mixed with 50 mL of water and 0.3 mL of sodium hydroxide (50% active). The mixture is boiled on a hot plate for at least 1 hour, while avoiding the mixture from drying out. After 1 hour, the mixture is allowed to cool and the pH is adjusted to neutral (pH 6-8) with 25% sulfuric acid using pH strips or a calibrated pH electrode.

[0172] The fatty acids are then extracted from the mixture by acidic liquid-liquid extraction with hexane or petroleum ether: the sample mixture is diluted to 160 mL with water / ethanol (1:1) in an extraction cylinder and 5 grams of sodium chloride, 0.3 mL of sulfuric acid (25% active), and 50 mL of hexane are added. The cylinder is capped and shaken for at least 1 minute. The cylinder is then allowed to sit until two layers form. The top layer containing the fatty acids in hexane is transferred to another receiver. The hexane is then evaporated using a hot plate, leaving behind the extracted fatty acids.

[0173] The iodine value of the parent fatty acid forming the fabric conditioning active is then measured according to ISO 3961:2013. The method for calculating the iodine value of the parent fatty acid involves dissolving a defined amount (0.1-3 g) in 15 mL of chloroform. The dissolved parent fatty acid is then reacted with 25 mL of iodine monochloride in acetic acid solution (0.1 M). To this is added 20 mL of 10% potassium iodide solution and 150 mL of deionized water. After the addition of the halogen is performed, the excess of iodine monochloride is measured by titration with sodium thiosulfate solution (0.1 M) in the presence of blue starch indicator powder. At the same time, a blank is measured under the same conditions with the same amount of reagents. The iodine value can be calculated by the difference between the amount of sodium thiosulfate used in the blank and the amount used to react with the parent fatty acid.

[0174] Methods for determining fatty acid chain length distribution The fatty acid chain length distribution of quaternary ammonium ester fabric conditioning actives refers to the chain length distribution of the parent fatty acids that form the fabric conditioning actives. It can be measured on the quaternary ammonium ester conditioning actives or on the fatty acids extracted from the fabric softener composition, as described in the method for measuring the iodine value of quaternary ammonium ester fabric conditioning actives. The fatty acid chain length distribution is measured by dissolving 0.2 g of quaternary ammonium ester conditioning actives or the extracted fatty acids in 3 mL of 2-butanol, adding three glass beads, and vortexing the sample at high speed for 4 minutes. An aliquot of this extract is then transferred to a 2 mL gas chromatography vial, which is then injected into the gas chromatogram inlet (250°C) of a gas chromatograph (Agilent GC6890N), and the resulting by-products are separated on a DB-5ms column (30 m x 250 μm x 1.0 μm, 2.0 mL / min). These by-products are identified using a mass spectrometer (Agilent MSD5973N, Chemstation software version E.02.02) to measure the peak areas of the corresponding fatty acid chain lengths. The fatty acid chain length distribution is determined by the relative ratio of the peak area corresponding to each fatty acid chain length of interest compared to the sum of all peaks corresponding to all fatty acid chain lengths.

[0175] Volume-weighted median inclusion size Inclusion body size is measured using an Accusizer 780A from Encapsulate Sizing Systems (Santa Barbara CA). The instrument is calibrated from 0 to 300μ using Duke inclusion body size standards. Samples for inclusion body size assessment are prepared by diluting approximately 1g of emulsion if measuring the volume weighted median inclusion body size of emulsions, or 1g of capsule slurry if measuring the volume weighted median inclusion body size of finished capsules, into approximately 5g of deionized water and further diluting approximately 1g of this solution into approximately 25g of water.

[0176] Using the auto dilution feature, approximately 1g of the most diluted sample is added to the Accusizer and the test is started. The Accusizer should read above 9200 counts / sec. If the count is below 9200, additional sample should be added. The Accusizer will dilute the test sample until it reaches 9200 counts / sec and begin the evaluation. Two minutes after the test, the Accusizer will display the results including the volume weighted median size.

[0177] By determining the inclusion body size beyond which 95% of the cumulative inclusion body volume is exceeded (95% size), the inclusion body size beyond which 5% of the cumulative inclusion body volume is exceeded (5% size), and the volume-weighted median size (50% size: both the inclusion body volume above this size and the inclusion body volume below this size are 50% of the inclusion body volume), the broadness index (5) can be calculated: broadness index (5) = ((95% size) - (5% size) / 50% size).

[0178] Freshness Headspace Analysis Method for Fabrics To prepare the fabric for analysis, cut one 2.54 cm x 5.08 cm piece of cotton fabric from the cotton terry fabric prepared and treated according to the method described above. Place each piece in a 20 mL headspace vial. Re-equilibrate for 4 hours in a humidity and temperature (21 C / 50% humidity) controlled room. After 4 hours, the vials were capped and analyzed via headspace solid phase microextraction / gas chromatography / mass spectrometry.

EXAMPLES

[0183] The examples provided below are intended to be illustrative and not limiting in nature.

[0184] For the formulation examples which follow, unless otherwise indicated, ingredients are identified according to the following key:

[0185] [Table 1]

[0186] Example 1. Preparation of quaternary ammonium poly alpha-1,3-glucan These examples describe the preparation of a quaternary ammonium poly alpha-1,3-glucan ether derivative. Specifically, trimethylammonium hydroxypropyl poly alpha-1,3-glucan was prepared.

[0187] A. Preparation 1 A 4-neck 1 L round bottom flask equipped with a metal / mechanical stirring rod, thermocouple, addition funnel, and condenser topped with a N2 inlet was charged with 130.0 g (0.325 mol) of wet cake glucan (40.5 wt% glucan, DPw 800 (~120,000 MW), ground to 180-300 microns, containing 52.7 g glucan and 77 g water) and 300 mL of isopropanol. The mixture was stirred (20-26 °C) while 34.6 g of 50 wt% sodium hydroxide solution was added over 10 minutes. The mixture was stirred at room temperature for 15 minutes and then heated to 60 °C. 3-Chloro-2-hydroxypropyltrimethylammonium chloride (107 g, 60% in water) was added over 5 minutes. The reaction was stirred at 58-61 °C for 4 hours. The reaction mixture was very viscous and was cooled to about 35° C. and filtered to give a wet cake (attempts were made to remove as much liquid as possible by house vacuum and pressing). The wet cake was mixed with water (3 L) and treated with HCl (18.5 wt %) to a pH of about 7. The mixture was filtered to remove any solids. Very little solids were collected. The filtrate was further purified by TFF (MWCO 30K PES membrane). The retentate was dried to give a solid (71.1 g). Based on NMR, the DS is 0.49 for the cationic polyglucan.

[0188] B. Preparation 2 10 g of poly α-1,3-glucan (M wA 500 mL round-bottom flask (weight average molecular weight = 168,000) was added to 100 mL of isopropanol in a 500 mL round-bottom flask equipped with a thermocouple for temperature monitoring, a condenser connected to a recirculating bath, and a magnetic stir bar. 30 mL of sodium hydroxide (17.5% solution) was added dropwise to the preparation, which was then heated to 25 °C on a hot plate. The preparation was stirred for 1 h and then warmed to 55 °C. 3-Chloro-2-hydroxypropyl-trimethylammonium chloride (31.25 g) was then added to provide a reaction which was held at 55 °C for 1.5 h and then neutralized with 90% acetic acid. The solid thus formed (trimethylammonium hydroxypropyl poly alpha-1,3-glucan) was collected by vacuum filtration, washed four times with ethanol (95%), dried under vacuum at 20-25 °C, and analyzed by NMR and SEC to determine molecular weight and DoS.

[0189] Additional samples of trimethylammonium hydroxypropyl poly alpha-1,3-glucan were synthesized according to the method described above with certain process variations. W A poly alpha-1,3-glucan sample having the formula: ##STR00011## was used as the starting material, and different amounts of etherification agent (3-chloro-2-hydroxypropyl-trimethylammonium chloride) were used. Also, the reaction time (starting with the addition of the etherification agent and ending with neutralization) was varied. These various process variables and the resulting DoS measurements of the quaternary ammonium glucan ether product are listed in Table 1.

[0190] [Table 2] a The reaction time was measured from the time the etherification agent was added to the time the reaction was neutralized.

[0191] Example 2. Exemplary Liquid Fabric Enhancers The liquid fabric enhancer can be prepared by mixing the listed ingredients in the ratios shown in Table 2. Unless otherwise specified, percentages are by weight of active ingredient.

[0192] [Table 3]

[0193] Example 3. Cationic polyglucan improves the secant modulus of fabrics The following test was carried out to demonstrate that the presence of certain cationic polyglucan compounds can improve the performance of a liquid conditioning composition at two different levels of fabric softening active (8% and 4% by weight).

[0194] Fabric is treated according to the fabric preparation method described above. The liquid conditioning composition is a liquid fabric strengthener according to the formula shown in Table 3 below. Formulas III and V contain cationic polyglucan compounds, while formulas II and IV, as comparative examples, do not. For each example, 49.5 g / dose of the fabric strengthener composition is provided. After treatment, the secant modulus of the fabric is determined using an Instron instrument according to the method described above. The results are shown in Table 3 below.

[0195] [Table 4] 1 Polyglucan ether: A poly alpha-1,3-glucan ether compound according to the present disclosure; SEC (MW) = 140,000; Cation DoS = 0.5; substituted with trimethylammonium hydroxypropyl groups

[0196] As shown in Table 3, the presence of polyglucan compounds reduces the secant modulus of the fabric, which is typically associated with increased softness.

[0197] Example 4. Effect of molecular weight The following test was performed to demonstrate the effect of the molecular weight of the cationic polyglucan compound on the secant modulus value.

[0198] Fabric is treated according to the fabric preparation method described above. The liquid conditioning composition is a liquid fabric strengthening agent according to the formula shown in Example 2 above, and the cationic polyglucan compound is changed as shown below. For each example, 60g / dose of the liquid conditioning composition is provided. After treatment, the secant modulus of the fabric is determined using an Instron instrument according to the method described above. The results are shown in Table 4A and Table 4B.

[0199] [Table 5]

[0200] [Table 6]

[0201] Lower secant coefficient values ​​are associated with increased flexibility. Thus, the data in Tables 4A and 4B show that polymers according to the present disclosure having a weight average molecular weight of, for example, greater than 78,000 daltons and less than 242,000 daltons (preferably about 99,000 to about 150,000 daltons) provide improved flexibility benefits compared to the comparative compounds in the formulations tested.

[0202] Example 5. Effect of degree of cation substitution The following test is carried out to demonstrate the effect of the degree of cationic substitution of cationic polyglucan compounds on the secant coefficient values: Polymers of similar molecular weight but different degrees of cationic substitution (DoS) are selected.

[0203] Fabric is treated according to the fabric preparation method described above. The liquid conditioning composition is a liquid fabric strengthener according to the formula shown in Example 2 above, and the cationic polyglucan compound is varied as shown below. For each example, enough composition is added to provide 9.6 grams of softening active per dose. After treatment, the secant modulus of the fabric is determined using an Instron instrument according to the method described above. The results are shown in Table 5.

[0204] [Table 7]

[0205] Lower secant coefficient values ​​are associated with increased softness. Thus, the data in Table 5 show that increasing the degree of cationic substitution (DoS), at least up to a certain point, can provide improved softness benefits in liquid fabric strengthening compositions.

[0206] Example 6. Comparison of Polyglucans to Other Polysaccharides The following tests were carried out to demonstrate the relative effectiveness of cationic polyglucan compounds compared to other cationic polysaccharide compounds.

[0207] Liquid conditioning compositions having the formula according to Table 6A are prepared using different cationic polysaccharides as shown below.

[0208] [Table 8]

[0209] Fabrics are treated according to the fabric preparation method described above. The liquid conditioning compositions are liquid fabric strengtheners according to the formula shown in Example 2 above, with the cationic polysaccharides varying as shown below. A non-polysaccharide control is also prepared (Example 11 below). For each example, enough composition is added to provide 3 grams of softening active per dose. After treatment, the secant modulus of the fabrics is determined using an Instron instrument according to the method described above. Additionally, the Brookfield viscosity of each liquid conditioning composition is determined according to the method described above. The results are shown in Table 6B.

[0210] [Table 9] 1 LR400: Polyquaternium-10; SEC(MW)=400,000; Cation DoS=0.19 2Celquat L200: Polyquaternium-4; SEC(MW)=303,000; Cation DoS=0.45 3 Polyglucan ether: A poly alpha-1,3-glucan ether compound according to the present disclosure; SEC (MW) = 145,000; Cation DoS = 0.50; substituted with trimethylammonium hydroxypropyl groups

[0211] The results in Table 6B show that the glucan ether compounds according to the present disclosure can provide similar softening effects (as shown by the secant modulus data) as those provided by other known cationic polysaccharides. However, the product viscosities associated with the glucan ether compounds are relatively lower than other compositions. Lower viscosity can improve dispensing experience and reduce machine residue.

[0212] Example 7. Freshness Examples of Cationic Polyglucan in Liquid Fabric Enhancers The following test was carried out to demonstrate that the presence of certain cationic polyglucan compounds can improve the freshness performance of liquid conditioning compositions.

[0213] Fabric is treated according to the fabric preparation method described above. The liquid conditioning composition is a liquid fabric strengthening agent according to the formula shown in Table 7 below. Formula VIII contains cationic polyglucan compound, and formula VII as a comparative example does not. For each example, 48.5 grams of liquid fabric strengthening agent is added per dose. After treatment, fabric headspace analysis is performed using gas chromatography equipment according to the method described above. Results are shown in Table 7 below.

[0214] [Table 10] 1 Polyglucan ether: A poly alpha-1,3-glucan ether compound according to the present disclosure; SEC (MW) = 145,000; Cation DoS = 0.50; substituted with trimethylammonium hydroxypropyl groups

[0215] As shown in Table 7, fabrics treated with Formulation VIII provide a greater amount of perfume material in the headspace.

[0216] Example 8. Additional Liquid Fabric Enhancer Examples Table 8 shows additional exemplary liquid fabric enhancer compositions.

[0217] [Table 11]

[0218] Example 9. Additive formulation and softening effect This example shows the specific effect of cationic polyglucan compound in solid pastille additive formulation. Fabric is treated according to the fabric preparation method described above, and pastille additive is added in the wash cycle. The composition of the pastille additive is according to the formula shown in Table 9 below. Formula XV contains cationic polyglucan compound, and formula XIV, as a comparative example, does not. For each example, 32g of pastille additive formulation is added per dose. After treatment, the secant coefficient is determined using an Instron instrument according to the method described above. The results are shown in Table 9 below.

[0219] [Table 12] 1 PEG: Polyethylene glycol (PLURIOL E8000, manufactured by BASF) 2 Polyglucan ether: Poly alpha-1,3-glucan ether compound according to the present disclosure; SEC (MW) = 139,000; Cation DoS = 0.40; substituted with trimethylammonium hydroxypropyl groups

[0220] As shown in Table 9, fabrics treated with Formulation XV provided relatively lower secant modulus values ​​compared to comparative Formulation XIV, indicating improved softness.

[0221] Example 10. Detergent formulation and fragrance deposition This example shows the specific effect of cationic polyglucan compound in heavy duty liquid detergent.More specifically, cationic polyglucan compound is added to a liquid detergent composition (liquid GAIN®, The Procter & Gamble Company), and then the detergent is used to treat fabric.The treated fabric is evaluated for average perfume deposition, which is compared to the fabric treated with unmodified detergent.

[0222] The average perfume deposition on the fabric is determined as follows: A weighed amount of fabric is extracted using a set volume of an alcohol-based solvent to remove perfume components. The solute is then combined with an internal standard and injected into a GC-MS. The perfume peaks are identified and normalized to a quantitative value using typical chromatographic techniques.

[0223] The results are shown in Table 10 below.

[0224] [Table 13] 1 Polyglucan ether: Poly alpha-1,3-glucan ether compound according to the present disclosure; SEC (MW) = 139,000; Cation DoS = 0.40; substituted with trimethylammonium hydroxypropyl groups

[0225] The results in Table 1 show that the liquid laundry detergent containing the polyglucan according to the present disclosure resulted in a relative increase in perfume deposition.

[0226] Example 11. Detergent and Softener In this example, a commercially available heavy-duty laundry detergent (liquid BOLD® detergent, sold in Japan, manufactured by Procter & Gamble) is provided. A polyglucan according to the present disclosure is provided in a portion of the detergent. Fabric samples are washed with each detergent and scored for softness by a panel. The results are provided in Table 11.
