Description

FABRIC CARE COMPOSITIONSCROSS-REFERENCED TO RELATED APPLICATIONS

[0001] The present application claims the benefit of priority to United States Provisional Patent Application Serial No. 63 / 738,253, filed December 23, 2024, the entirety of which is incorporated herein by reference.BACKGROUND

[0002] Typical malodor in clothes may be eliminated with a traditional washing cycle. However, these odors become stubborn when non-washed-out residues accumulate in fabrics, forming a combination of body sebum, deodorant, detergent, and fabric softener. In such cases, traditional detergents, which are based on a blend of surfactants, are insufficient to wash away and eliminate those residues causing the malodors.

[0003] A typical laundry cycle includes one wash cycle and one or two rinse cycles. Laundry detergents, commonly used in the wash cycle, are alkaline (pH 8.0 to 9.5) and aid in removing greasy soils like body grime and sweat from clothing. When sebum penetrates fabric and accumulates, it can form covalent chemical bonds with other residues, such as deodorants. This results in persistent malodors that cannot be removed by a traditional washing process.

[0004] Laundry detergent compositions, which typically include surfactant, are known to provide benefits to fabrics through the wash cycle of an automatic washing machine. Additionally, other laundry additive compositions, which may be substantially free of surfactant, are known to provide benefits to fabrics through the rinse cycle. However, many common compositions may not be desirable to consumers for various reasons. For example, fabric softeners are generally popular, but certain consumers may not wish for fabric softening actives to be deposited onto their fabrics. Some may use vinegar in the rinse, but the performance (and odor of the vinegar) may leave something to be desired. Products with natural ingredients, low viscosities, and / or transparent properties may also be desired.

[0005] Additionally, laundry compositions and treatment compositions that can provide multiple benefits are typically desirable. Thus, there is a need for compositions and processes that provide improved performance, preferably along multiple benefit vectors, particularly through the rinse and / or in combination with a detergent composition or wash cycle. Moreover, it is also desirableto have single wash cycle eliminate sebum and other contaminants. Certain embodiments of the present invention are designed to meet these and other ends.BRIEF SUMMARY

[0016] For illustrative purposes, the principles of the present invention are described by referencing various exemplary embodiments thereof. Although certain embodiments of the invention are specifically described herein, one of ordinary skill in the art will readily recognize that the same principles are equally applicable to, and can be employed in other apparatuses and methods. Before explaining the disclosed embodiments of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of any particular embodiment shown. The terminology used herein is for the purpose of description and not of limitation.

[0017] As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural references unless the context dictates otherwise. The singular form of any class of the ingredients refers not only to one chemical species within that class, but also to a mixture of those1070889-00-WQ-01-HCchemical species. The terms “a” (or “an”), “one or more” and “at least one” may be used interchangeably herein. The terms “comprising”, “including”, and “having” may be used interchangeably. The term “include” should be interpreted as “include, but are not limited to”. The term “including” should be interpreted as “including, but are not limited to”.

[0018] As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.

[0019] The term “about” when referring to a number means any number within a range of 10% of the number. For example, the phrase “about 2 wt.%” refers to a number between and including 1.8 wt.% and 2.2 wt.%.

[0020] All references cited herein are hereby incorporated by reference in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.

[0021] The abbreviations and symbols as used herein, unless indicated otherwise, take their ordinary meaning. The abbreviation “wt.%” means percent by weight with respect to the fabric care composition. The symbol “°” refers to a degree, such as a temperature degree or a degree of an angle. The symbols “h”, “min”, “mL”, “nm”, and “pm” refer to hour, minute, milliliter, nanometer, and micrometer, respectively. The abbreviation “UV-VIS” as referring to a spectrometer or spectroscopy, means Ultraviolet-Visible. The abbreviation “rpm” means revolutions per minute.

[0022] When referring to chemical structures, and names, the symbols “C”, “H”, and “O” mean carbon, hydrogen, and oxygen, respectively. The symbols“=” and “=” mean single bond, double bond, and triple bond, respectively.

[0023] “Volatile”, as used herein, means having a flash point of less than about 100° C. “Nonvolatile”, as used herein, means having a flash point of greater than about 100° C.

[0024] Any member in a list of species that are used to exemplify or define a genus, may be mutually different from, or overlapping with, or a subset of, or equivalent to, or nearly the same as, or identical to, any other member of the list of species. Further, unless explicitly stated, such as when reciting a Markush group, the list of species that define or exemplify the genus is open,1070889-00-WQ-01-HCand it is given that other species may exist that define or exemplify the genus just as well as, or better than, any other species listed.

[0025] The phrases, “a mixture thereof,” “a combination thereof,” or a combination of two or more thereof’ do not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.” Likewise, the term “a salt thereof’ also relates to “salts thereof.” Thus, where the disclosure refers to “an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof,” it indicates that that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included.

[0026] All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the fabric care compositions of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure. In some instances, the fabric care compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound that is added into the fabric care composition by itself. For example, a fabric care composition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds.

[0027] Some of the various categories of components identified may overlap. In such cases where overlap may exist and the fabric care composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, certain compounds may be characterized as both a lubricant and a glidant. If a particular fabric care composition includes both a lubricant and a glidant, a compound that may be characterized as both a lubricant and a glidant will serve only as either a lubricant or a glidant — not both.

[0028] For readability purposes, the chemical functional groups are in their adjective form; for each of the adjectives, the word “group” is assumed. For example, the adjective “alkyl” without a noun thereafter, should be read as “an alkyl group”.

[0029] As used herein the phrase “fabric care composition” includes compositions and formulations designed for treating fabric. Such compositions include but are not limited to, laundry cleaning compositions and detergents, fabric softening compositions, fabric enhancing compositions, fabric freshening compositions, laundry prewash, laundry pretreat, laundry additives, spray products, laundry rinse additive, wash additive, post-rinse fabric treatment, unit dose formulation, delayed delivery formulation, detergent contained on or in a porous substrate or nonwoven sheet, and other suitable forms that may be apparent to one skilled in the art in view of the teachings herein. Such compositions may be used as a pre-laundering treatment, a postlaundering treatment, or may be added during the rinse or wash cycle of the laundering operation.

In some embodiments, the colorants may be present in an amount ranging from about 0.0001 to about 4 wt.%, including all percentages and subranges therebetween, based on the total weight of the fabric care composition. In certain embodiments, in order to prevent ingredients from separating, emulsifiers may be added.

[0065] The fabric care composition may include one or more pH adjusters to increase or decrease the overall pH of the fabric care composition. Without being limited to any particular theories, certain embodiments advantageously are free of pH adjusters.

[0066] In certain embodiments, the fabric care composition has a pH of from about 4 to about 10.0. In other embodiments, the fabric care composition has a pH of from about 4.5 to about 8.0.

[0067] In some embodiments, the compositions of the present invention comprise lactic acid and citric acid in a weight ratio of from about 0.1 : 10 to about 10 : 0.1, or from about 1 : 10 to about 10 : 1, or about 0.1 : 9 to about 9 : 0.1, or about 1 : 9 to about 9 : 1, or about 0.1 : 6 to about 6 : 0.1. or about 1 : 6 to about 6 : 1, or about 0.1 : 4 to about 4 : 0.1. or about 1 : 4 to about 4 : 1, or about 0.1 : 3.5 to about 3.5 : 0.1, or about 1 : 3.5 to about 3.5 : 1, or about 1.5 : 3.5 to about 3.5 : 1.5, or about 2 : 9 to about 9 : 2, or about 4 : 6 to about 6 : 4, or about 1 : 3 to about 3 : 1, or about 1 : 2 to about 2 : 1, or about 1 : 1, or about 3 : 3.5, or about 1.5 : 3.5, or 1.5 : 6.25 to about 6.25 : 1.5, or about 3 : 6.25 to about 6.25 : 3.

[0068] In accordance with further aspects of the disclosure, provided is a process of treating a fabric. The fabric may be treated in one or more treatment liquors, e.g., during a wash cycle in a washing machine. The treatment liquors may be obtained by combining the fabric care compositions with water and optionally a fabric detergent, fabric softener, and / or fabric conditioner. As described below, the process may comprise the step of contacting the fabric with a rinse liquor, which may be subsequent to contacting the fabric with a wash liquor.

[0069] The process may occur in any vessel suitable for containing such treatment liquors and fabrics. The vessel may be a basin suitable for a manual treatment process, such as a wash tub in which the fabrics are treated by hand. More preferably, the vessel is part of an automatic washing machine, such as the drum of an automatic washing machine. The drum is sized and dimensioned to suitably receive the fabrics and water. The process may comprise the step of providing the fabric to the vessel, for example to a drum of an automatic washing machine. The automatic washing machine may be a top-loading washing machine or a front-loading washing machine.

[0070] The fabric may be any fabric or article comprising fabric suitable for being treated by a laundering process. Suitable fabrics may include garments, linens, and the like. The fabric may comprise any suitable material or fiber type, such as cotton, polycotton, or other fiber types. The fabric may comprise natural fibers.

[0071] The fabric may comprise an odorant prior to being treated. Thus, the processes of the present disclosure may include providing a fabric, where the fabric comprises an odorant. The odorant may be a residual odorant that remains from a previous use of the fabric.

[0072] The odorant may be perfume. The perfume may be derived from a fine fragrance that was applied directly to a fabric (e.g., a garment) or to a user / wearer of the fabric (e.g., a garment) that1070889-00-WQ-01-HCrubbed off onto the fabric. The perfume may be derived from a perfume that was part of a fabric treatment product, such as a detergent or fabric softener, previously used to treat the fabric.

[0073] The odorant may comprise aldehydic materials. Such materials are often present in perfumes used in fine fragrances and household products such as laundry products. It is believed that the compositions and processes of the present disclosure are surprisingly effective at removing aldehydic materials.

[0074] The odorant may be derived from body soil, for example sweat and / or sebum. The odorant derived from body soil may remain on the fabric from a previous use or wear. Without wishing to be bound by theory, it is believed that certain sequestration agents, in addition to sequestering calcium, may also effectively sequester copper ions, which may facilitate the decomposition of certain body soils into malodorous materials. Thus, by sequestering copper, for example with citric acid, the formation of malodorous materials is inhibited or reduced.

[0075] The wash step may comprise providing a detergent composition. The detergent composition may be in any suitable form. For example, the detergent composition may be in the form of a liquid composition, a granular composition, a single-compartment pouch, a multicompartment pouch, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a bar, a flake, a dryer sheet, or a mixture thereof. The detergent composition can be selected from a liquid, solid, or combination thereof.

[0076] The process may include a step of combining a laundry detergent composition with water to form a wash liquor. The process may further comprise the step of contacting a fabric with the wash liquor, preferably in a vessel, such as a drum of an automatic washing machine. The process may include the step of agitating the mixture of the fabric and / or the wash liquor, for example by rotating the drum or a center agitation post of the machine.

[0077] Typically, the water is added to the vessel. The laundry detergent composition may be added directly, in neat form, to the water to form the wash liquor. The laundry detergent composition may be added via a dispensing drawer of an automatic washing machine. The laundry detergent may be added to the vessel prior to the water being added to the vessel. The laundry detergent may be contacted with the fabric, for example in a pretreatment step, prior to being combined with the water.

[0078] The process may include the step of removing the wash liquor from the vessel, for example by draining the wash liquor, which may be assisted by gravity and / or spinning the vessel. It isunderstood that not 100 wt.% of the wash liquor may be removed from the vessel. For example, residual wash liquor may be left in the vessel and / or remain absorbed by the fabric. The process may include removing at least 70 wt.%, or at least 80 wt.%, or at least 90 wt.%, by weight of the wash liquor, of the wash liquor from the vessel.

[0079] The processes of the present disclosure may comprise a rinse step. The rinse step may occur during a rinse cycle of an automatic washing machine. A rinse step typically follows a washing step and may be intended to remove at least some of the benefit agents provided in a wash steps, such as surfactant. The rinse step may also help to remove soils that have been loosened during a rinse step but were not removed when the wash liquor was removed from the treatment vessel.

[0080] Furthermore, the rinse step can be used to provide additional benefit agents by way of employing a fabric care composition disclosed herein. Traditionally, certain laundry products, such as liquid fabric softeners, have been added during a rinse step. However, certain consumers may not wish to use these traditional products on their fabrics, given that such products may deposit compounds such as softening active agents on the fabrics. Additionally, certain fabrics, such as certain synthetic fabrics, are not suitably treated with such products.

[0081] The processes of the present disclosure may provide treatment benefits to fabrics in a rinse step as an alternative to the use of a traditional rinse-added product, such as a liquid fabric softener. To note, although the present disclosure generally discusses the processes as being part of a “rinse step” that follows a “wash step,” the processes of the present disclosure may include a rinse step without a preceding wash step. Thus, the rinse steps of the present disclosure may occur independently of a wash step, for example as a stand-alone treatment and / or soaking process. The rinse step of the present disclosure may even precede a wash step in a multi-step process.

[0082] The processes of the present disclosure may include contacting fabric with a rinse liquor, which may be an aqueous rinse liquor. The contacting may occur in a vessel, such as the drum of an automatic washing machine. When the rinse step follows a wash step, the rinse step may occur in the same vessel in which the wash step occurred. The rinse liquor may comprise the fabric care composition.

[0083] The process of the present disclosure may include additional steps. For example, the process may include a pretreatment step, wherein the fabric and / or a soil thereon is contacted with a composition, solvent, or liquor intended to provide a benefit, particularly a benefit upon subsequent treatment steps. For example, the fabric and / or soil may be contacted with a1070889-00-WQ-01-HCcomposition that comprises surfactant and / or a bleaching system. The composition provided in a pretreatment step may be in any suitable form, such as a liquid, a spray, a bar, or a stick (e.g., a gel stick). The composition may be pretreated with a solvent, such as water or an organic solvent. Pretreatment with a solvent may include spraying the solvent onto the fabric or soaking the fabric in the solvent. A composition may be dissolved or dispersed in water to form an aqueous pretreatment liquor, which may then be used to contact the fabric, for example as a spray or as a soaking solution. The liquor may comprise surfactant or bleach. The process may include employing a fabric care composition disclosed herein during a pretreatment step, a wash step, a rinse step, or in a plurality thereof.

[0084] Odorous molecules show a preferential sorption affinity for polyester compared to natural fiber like cotton. The odor-causing compounds that stubbornly resist washing out, results in persistent, unpleasant smells. These buildups need a chemically distinct phase, such as an acidic wash or rinse, to disrupt the established non-polar binding domains and accumulated residues.

[0085] The persistent malodors fall into two main chemical categories (see, Table 1 below), each requiring a specific neutralization strategy.Table 1

[0086] Acidic Odors: These are typically Volatile Fatty Acids (VFAs), also referred to as Short-Chain Fatty Acids (SCFAs). Examples include isovaleric acid (associated with strong, sweaty or cheesy odors) and branched-chain fatty acids like 3-methyl-2-hexenoic acid and octanoic acid. These compounds are particularly problematic in synthetic textiles. Polyester fabrics tend to exhibit and retain higher total peak values of carboxylic acids even following laundering, making the removal of these acidic components a prime target for effective rinse aid chemistry.

[0087] Basic Odors: These odors consist of volatile amines and ammonia compounds, which are often characterized by fishy or ammoniacal notes. Standard alkaline detergents, optimized for general cleaning, are not equipped to completely disrupt the unique binding of odorous molecules sequestered within the non-polar entrenched core of the synthetic fibers. These physicochemical reasons validate the necessity of an acidic wash or rinse phase.

[0088] Without being bound by theory, it is believed that the weak acids (i.e.. citric acid and lactic acid) present in certain exemplary formulas of the present invention provide a low pH product that addresses trapped residues and odors. Specifically, both citric acid, a triprotic acid (pKal = 3.13) and lactic acid, a monoprotic acid (pKa = 3.86) generate a controlled acidic environment, typically yielding a rinse bath pH between 4 and 6. These organic acids introduce a massive concentration of protons (H+) via the acidic rinse and chemically reverse the sequestration of acidic odorant and chemically neutralize basic odorants. This acidic intervention is critical because the hydrophobic polymer (i.e., synthetic fibers like polyester) resists standard alkaline cleaning methods. The application of a low pH environment provides the necessary chemical leverage, acting as a specialized chemical desorption phase to mobilize the trapped odorants.

[0089] In some embodiments, the efficacy of organic acids (e.g., citric acid and lactic acid) may involve an acid-base reaction targeting the dual chemical classes of malodors: volatile amines and volatile fatty acids. In some embodiments, the mechanism involves the acid-base neutralization of basic odors (e.g., amines). Volatile amines (RNH2) (fishy or ammoniacal odors) are bases. In some embodiments, the citric acid and lactic acid (HA=organic acids) present in the wash or rinse cycle act as proton donors, initiating a simple yet effective neutralization reaction, in which the volatile amine is converted into an ionic salt, an ammonium ion (RNH3+):RNH2 (volatile) + HA RNH3+ + A- (Non- Volatile Salt).

[0090] The formation of the resulting ionic ammonium salt (RNH3+X-) is key to odor elimination. Unlike the parent amine, which is volatile and easily evaporates into the surrounding air (headspace), the ionic salt is highly polar, hydrophilic and possesses a dramatically reduced vapor pressure. In some embodiments, this conversion traps the malodorous compound within the aqueous phase solution (wash or rinse cycle), effectively eliminating the olfactory sensation (e.g., using lemon to eliminate fish odor).

[0091] In other embodiments, the mechanism involves pH-induced desorption of acidic odors (VFAs / SCFAs). In certain embodiments, this mechanism combats the persistent, sweaty odors, characterized by trapped carboxylic acids (VFAs) in polyester. The acidic environment forces the protonation of carboxylate anion (RCOO-) trapped near or within the fiber matrix:RCOO- (Adsorbed Anion) + H+ — > RCOOH (Neutral Acid)

[0092] In some embodiments, this shift is favorable when the water pH is lower than the pKa of the VFA (typically pH<4.5). The result is the conversion of a charge, polar anion back into itsneutral, less polar, protonated carboxylic acid form (RCOOH). In other embodiments, this change in molecular polarity has two major effects on desorption kinetic and efficiency: 1) Disruption of Ionic Trapping: The removal of the negative charge (RCOO-) eliminates the polar attractive forces that may have been binding the odorant to residual alkaline salts or potential cationic sites in the fiber structure; and 2) Partitioning Back into Water: The neutral VFA molecules (RCOOH) are thermodynamically less stable when sequestered within the hydrophobic, non-polar polymer core of the synthetic fiber compared to the surrounding aqueous phase. This reduction in affinity for the fiber / residues matrix promotes the movement, or partitioning, of the neutral VFA molecule into the bulk water. Once in the aqueous phase, the VFA is easily carried away by the volume of water, resulting in effective removal of the persistent odor. It is believed that both citric acid and lactic acid are ideal because their pKa values allow them to maintain a sufficiently low water pH to drive this protonation reaction, ensuring a maximized chemical desorption, particularly for long-chain VFAs.EXAMPLESExample 1

[0093] Two non-limiting example fabric care compositions (Example Compositions A and B) were prepared in accordance with aspects of the disclosure. Example Compositions A and B were prepared according to the formulations provided in Table 2 (below).Table 2>Example 2

[0094] Three non-limiting example fabric care compositions (Example Compositions C-E) having different fragrances were prepared in accordance with aspects of the disclosure. Example Compositions C-E were prepared according to the formulations provided in Table 3 (below).Table 3>Example 3

[0095] Example Composition C was evaluated to assess its efficacy in removing malodor. Specifically, twenty volunteers were asked to detect the odor of two swatches of washed and rinsed fabrics (93% polyester / 7% elastane). One fabric swatch was washed with only a detergent and rinsed with water while the other fabric swatch was washed with said detergent and rinsed with water and Example Composition C. The volunteers were asked to smell and select the sample swatch which they perceived had less malodor residue. The smelling sequence was randomized. The data was analyzed with a paired T-test for statistical significance. The results of the fragrance evaluation are shown in FIG. 1.Example 4

[0096] An additional exemplary composition of the present invention (Ex. F) was prepared in accordance with aspects of the disclosure. Its formulation is described below in Table 4 (below).Table 4>

[0097] Synthetic fabrics with a typical composition of about 93% polyester and about 7% elastane are used to evaluate the performance of the exemplary compositions of the present invention, as well as comparative compositions. Synthetic fabrics are more susceptible to odors because polyester and elastane are highly hydrophobic, and show little to no interaction with water; but they have an affinity for oils and greases.

[0098] In a 20 L plastic box, 1.5 g of cumin powder, 1.5 g onion powder and 1.5 g garlic powder are mixed with 15 L of tap water. This combination of ingredients mimics the smell created by bacterial metabolites, resulting in the mimicking of certain types of body odors. 130 pieces (20 cm X 20 cm) of synthetic fabric are soaked in the prepared solution.

[0099] The plastic box is covered, and the fabric pieces are kept inside the malodor solution for 3 days to acquire the desired strength of a lingering malodor. After 3 days, the fabric pieces are removed from the malodor solution, and the water is removed from the fabric pieces by spinning them in a washer (with no rinsing). The fabric pieces are then dried at room temperature overnight. The 3-day soaking time simulates the accumulation of malodors over time. This build up will result in residual odors despite washing with detergent.

[0100] The fabric pieces are stained with about 0.2 g of red dyed grease (blend of beef tallow, butter and olive oil, in equal amounts) to simulate the fatty acids left by the body grime (sebum). The section of each fabric piece where the malodor solution was applied is fully covered with thered dyed grease. The fabrics are allowed to rest for two (2) nights and are ready for evaluation on day three (3).

[0101] Two kilogram (2.0 kg) garment loads are made ready. Ten (10) pieces of odorous swatches are placed in each load. Ballast clothes are used to complete the total weight. The ballast clothes are not odorous.

[0102] Different short washing cycles were performed to evaluate an exemplary formula of the present invention in a complete laundry process. Two commercially available detergents (Comp.1 and Comp. 2) were also evaluated. Clean New Fabric was used as a control.

[0103] After the laundry cycle is finished, the swatches are line-dried overnight. When the samples are completely dry (the next day), they are ready for the tear drop evaluation.

[0104] To evaluate the performance in washing away greasy residues based on its active ingredient, five water droplets are placed on the stained portion of each swatch and the time it takes for the droplets to be completely absorbed is measured. Water absorbance time is an indirect measurement of the extent to which grease residues are broken down and washed away. Because the greasy layer deposited on fabric is hydrophobic, the longer it takes for the water droplets to be absorbed, the more residue remains on the fabric.

[0105] FIG. 2A and FIG. 2B capture the average time of absorption of water droplets on stained polyester / elastane fabrics. More specifically, FIG. 2A and FIG. 2B depict the performance of each formula tested compared to a positive control (clean fabric). Laundry detergents are specialized and complex formulas designed to eliminate grease residues and difficult stains from fabrics. However, to fully eliminate its residues and the generated foam, the rinse cycle is critical.

[0106] As illustrated in FIG. 2A and FIG. 2B, both commercial detergents (Comp. 1 and Comp.2) showed powerful grease elimination after the sixteen (16) minute wash cycle. The exemplary formula of the present invention (Ex. F) demonstrated similar cleaning performance during the same sixteen (16) minute wash cycle.

[0107] The results described in FIG. 2A and FIG. 2B suggest that exemplary formulas of the present invention can both clean and refresh light soiled fabrics during short cycles, avoiding the use of complex laundry detergents and fabric softeners. The results further suggest that formulas of the present invention are suitable for use on all fabrics; even showing strong performance for the most challenging fabric type: synthetic fabrics - with superior odor removal and freshness and that fights stubborn odors such as sweat, kitchen and humidity odors. These results are surprisingin view of the fact that the similarly formulated commercial product contained significantly more cleansing agent (citric acid) than the exemplary formula of the present invention.Example 5

[0108] Thirteen (13) formulas are evaluated in a Design of Experiment (DOE). As shown in Table 6 (below), the formulas include different levels of each organic acid, (i.e., 0 to 3.5 wt.% of lactic acid and 3.5 to 9 wt.% of citric acid) and are compared to an exemplary formula of the present invention that includes - in relevant part - 3.5 wt.% of citric acid) and a commercial laundry detergent. The evaluations are performed in the presence of fragrance to determine the impact of higher levels of organic acids in the fragrance hedonics.Table 5

[0109] The design gave four repeated runs (Run 2 = Run 9 I Run 3 = Run 7 / Run 4 = Run 8 I Run 11 = Run 12). For sensorial and instrumental evaluations, all the runs were evaluated to confirm reproducibility. An exemplary formula of the present invention (Ex. F) was used as a starting point for preparing the thirteen formulas evaluated in the DOE. The complete formulas are described in Table 6 (below).Table 6pH @ 25 °C / Viscosity = 100 to 400 cps

[0110] For each RUN, the amount of water was adjusted according to the addition of lactic acid and citric acid. The rest of the ingredients remained at the same levels as present in Ex. F. Please note that P2 and P9 correspond to Ex. F.

[0111] The materials and methods used in the DOE are the same as the materials and methods used in Example 4 (above). After the washing process is completed, sensorial and instrumental evaluations were conducted.

[0112] The ten (10) swatches are line-dried overnight and once they are completely dried (the next day), they are stored in aluminum paper to prevent odor deformation until they are evaluated by the fragrance experts after twenty-four (24) hours.

[0113] A fragrance technical assessment was carried out by trained fragrance experts in order to evaluate the malodor reduction performance of the different blends of lactic acid / citric acid in the 13 DOE runs. The primary goal was to determine if the different combinations and levels of organic acids resulted in a boosted malodor reduction performance, i.e., showing a synergistic effect, and thus offering a perceivable and meaningful improvement in malodor control actioncompared to Ex. F. The evaluations were made with full formulas (w / fragrance), compared against a commercially available detergent and Ex. F., both serving as controls.

[0114] The fragrance technical assessment is a controlled procedure involving three key phases: Preparation, Washing, and Olfactive Evaluation, designed to measure the malodor reduction efficacy of the studied technologies under realistic product usage conditions. The Preparation and Washing phases involve pre-dosing the evaluated fabrics with the standardized malodor blend to establish a consistent baseline. The fabrics are then washed either with a commercially available detergent, or Ex. F. Each test sample is dosed at the recommended consumer usage level of 60 mL per wash load.

[0115] The Olfactive Evaluation phase is the evaluation of the treated fabrics by a trained fragrance expert panel at the relevant wet and dry stages of product use. The Wet Stage assessment involves evaluating fabrics immediately following the washing process, to capture the prototypes’ immediate malodor neutralization efficacy on the damp fabric. For the Dry Stage assessment, treated fabrics are subsequently line-dried and evaluated after twenty-four (24) hours, capturing the effectiveness and durability of the malodor reduction when fabrics are dry, reflecting the actual consumer experience when garments are retrieved from storage or prepared for wear.

[0116] The fragrance experts score the fabrics based on a metric for malodor intensity anchored to a 1-10 scale (where 0 is no perceivable aroma and 10 is extremely strong aroma), allowing for comparisons of the lactic acid I citric acid rebalances against an established benchmark, in order to communicate the degree of malodor reduction.

[0117] Quantified malodor intensity scores for all evaluated samples are presented in FIG. 3A and FIG. 3B. In particular, FIG 3 A depicts Malodor Intensity scores for a first set of lactic acid I citric acid rebalanced prototypes (Replica 1); and FIG. 3B depicts Malodor Intensity scores for a second set of lactic acid / citric acid rebalanced prototypes (Replica 2).

[0118] In terms of malodor control performance. Ex. F (0.0% Lactic Acid / 3.5% Citric Acid) established the baseline for malodor reduction. An increase of Lactic Acid from 0.0% to 1.5% with a 3.5% citric acid level resulted in a detectable decrease of malodor intensity, suggesting that lactic Acid at a 1.5% level is effective for malodor mitigation. However, increasing the lactic acid to 3.0% with a 3.5% citric acid level resulted in no significant improvement in malodor control. Separately, increasing citric acid alone to 6.25% and 9.0% provided a moderate but consistentimprovement in malodor reduction, independent of lactic acid, suggesting it acts as an effective secondary booster.Example 6

[0119] A blinded consumer test was conducted to compare a commercially available product that includes an organic acid and an ethoxylated alcohol, with an exemplary composition of the present invention (Ex. F). Notably, the commercially available product contains a significantly higher concentration of organic acid compared to the concentration of organic acid present in the exemplary composition of the present invention. The evaluation consisted as well of testing two different doses of the present invention against the commercially available product at the recommended dose. Prior to the evaluation, consumers were advised that a well-known laundry manufacturer developed a new product designed to rinse away the smelly residues trapped within fabric fibers, to help remove malodors and leave your laundry fresher than ever. The product is added to the fabric softener compartment of the washing machine and used during the rinse cycle, after clothes were washed with commercially available laundry detergents. The study cohort was: a) twenty-one to sixty-five years old; b) responsible for doing laundry and purchasing laundry products for the household; and c) completed, on average, three or more washes per week.

[0120] The results of the consumer test illustrate that an exemplary composition of the present invention provided a significant improvement in the ability to remove one hundred percent of bad odors. Specifically, the exemplary composition (Ex. F) of the present invention was able to remove 100% of bad odors for fifty-seven percent (57%) of users whereas the comparative formula, which was a similarly formulated commercial product (Downy Rinse & Refresh), was only able to remove 100% of bad odors for forty-nine percent (49%) of users. This sixteen percent improvement is remarkable, as the similarly formulated commercial product contained significantly more cleansing agent / odor removal agent (citric acid) than the exemplary formula of the present invention.Example 7

[0121] A blinded consumer test was conducted to evaluate the performance of an exemplary composition of the presentation and a commercially available product that is similarly formulated. The products were evaluated for their ability to remove bad odors: sweat (Transportation drivers (bus, Uber and taxi) & people exercising in a gym); humidity; dirt (mechanics, construction and pollution exposure); and food (individuals working in restaurants and kitchens exposed to strongodors). Forty-eight (48) samples were washed with a commercially available laundry detergent prior to being rinsed with either the exemplary composition of the present invention or the commercially available product. After being washed with the commercially available laundry detergent, the 48 samples were split evenly: twenty-four (24) samples were rinsed with an exemplary composition of the present invention (Ex. F), and twenty-four (24) samples were rinsed with the commercially available product. Each sample contained two kilograms of dirty clothes, which included shirts (100% cotton & polyester), pants and socks (mixed fabric).

[0122] The results of the consumer test illustrate that an exemplary composition of the present invention was able to clean clothes without requiring a rewash, significantly better than the commercially available product, during a wet sample evaluation. Specifically, consumers found that eighty-seven percent (87%) of samples treated with an exemplary composition of the present invention were clean and did not need to be rewashed, whereas consumers found only seventy-five percent (75%) of samples treated with the commercial product (Downy Rinse & Refresh) were clean, and did not need to be rewashed. This sixteen percent improvement is remarkable, as the similarly formulated commercial product contained significantly more cleansing agent (citric acid) than the exemplary formula of the present invention.

[0123] It is understood, therefore, that this invention is not limited to the particular embodiments disclosed but is intended to cover all modifications which are within the spirit and scope of the invention as defined by the appended claims; the above description; and / or shown in the attached drawings.
