Description

DETAILED DESCRIPTION OF THE PREFERRED MODALITY The variations are not limited to specific manufacturing methods and / or formulations for stabilized detergent compositions, specifically alkaline laundry detergents, which can vary and are understood by experts in the field. It has been surprisingly discovered that a blend of alkali-swelling polymers (ASEs) and hydrophobically modified alkali-swelling polymers (HASEs) provides emulsion-stable detergent compositions without the need for premixes, homogenizers, or granulation processes for their production, yielding beneficial detergent compositions for various applications, including the washing of textiles and fabrics. Furthermore, these emulsion-stable detergent compositions are advantageously free of crosslinked or partially crosslinked polyacrylic and / or polymethacrylic acids. Furthermore, it should be understood that all terminology used herein is for the purpose of describing particular modalities only and is not intended to be limiting in any way or scope. For example, as used herein and in the appended claims, the singular forms “a” and “the” may include plural referents unless the content clearly indicates otherwise. In addition, all units, prefixes, and symbols may be stated in their SI-accepted form. Numerical ranges cited herein include the numbers within the defined range. Throughout the description, various aspects are presented in range format. It should be understood that the range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention.Therefore, the description of an interval should be considered to specifically describe all of them. RQ / Qnn / Lznz / E / Yi possible sub-intervals, as well as the individual numerical values ​​within that interval (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5). To facilitate understanding of the present invention, certain terms are first defined. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by a person skilled in the art to which the embodiments of the invention pertain. Many methods and materials similar to, modified from, or equivalent to those described herein may be used in the practice of the embodiments without excessive experimentation, but preferred materials and methods are described herein. In describing and claiming the embodiments, the following terminology shall be used in accordance with the definitions set forth below. The term “approximately,” as used herein, refers to the variation in numerical quantity that may occur, for example, due to typical procedures for measuring and handling liquids used in the manufacture of concentrates or solutions for real-world use; due to inadvertent error in these procedures; due to differences in the manufacture, source, or purity of the ingredients used to manufacture the compositions or carry out the methods; and the like. The term “approximately” also encompasses quantities that differ due to different equilibrium conditions for a composition resulting from a particular starting mixture. Whether or not modified by the term “approximately,” the claims include equivalents to the quantities. The expressions “actives” or “percentage of actives” or “weight percentage of actives” or “concentration of actives” are used interchangeably in this description and refer to the concentration of these ingredients included in the cleaning product expressed as a percentage less inert ingredients, such as water or salts. As used in this description, the term "free" refers to compositions that are completely free of the component or that contain such a small amount of the component that it does not affect the composition's performance. The component may be present as an impurity or contaminant and must be less than 0.5% by weight. Alternatively, the amount of the component is less than 0.1% by weight, and in yet another embodiment, the amount of the component is less than 0.01% by weight. The term “surfactant” or “surfactant agent” refers to an organic chemical substance that, when added to a liquid, changes the properties of that liquid at the surface. The term “percent by weight”, “% by weight”, “percent by weight”, and variations thereof, as used in the present description, refer to the concentration of a substance as the weight of that substance divided by the total weight of the composition and multiplied by 100. It is understood that, as used in the present description, “percent”, “%” and the like are intended to be synonymous with “percent by weight”, “% by weight”, etc. The methods and compositions may comprise, consist essentially of, or consist of the components and ingredients, as well as other ingredients, described herein. As used herein, “consisting essentially of” means that the methods and compositions RQ / Qnn / Lznz / E / Yi compositions may include additional steps, components or ingredients, but only if the additional steps, components or ingredients do not materially alter the basic and novel features of the claimed methods and compositions. Detergent compositions According to the embodiments, the detergent compositions include a very high concentration of highly alkaline surfactant with a stabilizing mixture of rheology modifiers, specifically, a mixture of alkali-swellable (ASE) polymers and hydrophobically modified alkali-swellable (HASE) polymers. The alkaline detergent compositions may include additional functional ingredients and may be supplied as concentrated or ready-to-use compositions. In some embodiments, the detergent compositions do not require and / or employ cationic surfactants to stabilize the emulsion compositions due to the stabilizing mixture of rheology modifiers. Table 1 shows illustrative detergent compositions in weight percent. TABLE 1 RQ / Qnn / Lznz / E / Yi Material First Illustrative Weight % Range Second Illustrative Weight % Range Third Illustrative Weight % Range Source of Alkalinity 1-70 1-50 10-50 HASE / ASE Rheology Modifiers 0.1-10 0.5-10 1-7 Surfactant(s) 1-70 1-50 10-50 Chelating / Sequestering Agent(s) 0-25 0.1-10 1-10 Water 10-80 20-70 30-60 Additional Functional Ingredients 0-90 0-75 0-50 Liquid detergent compositions have a viscosity range between approximately 500 and 2500 cPs, preferably between approximately 500 and 2000 cPs, preferably between approximately 1000 and 2000 cPs, or more preferably between approximately 700 and 1500 cPs (measured at 50 revolutions per minute (RPM) on a Brookfield RVT viscometer with a #3 spindle at room temperature or 25°C). This viscosity allows the liquid detergent concentrate to be dispensed by pouring and / or various pumping devices, eliminating the need for pumps modified for high-viscosity liquids. Detergent compositions are opaque, highly viscous dispersions. They can be concentrated or diluted to form ready-to-use solutions. Generally, a concentrate refers to a composition intended to be diluted with water to provide a ready-to-use solution that comes into contact with an object to achieve the desired cleaning effect. Beneficially, the detergent compositions are stable fluid emulsions that do not undergo phase separation during storage or when exposed to widely varying temperatures. Specifically, the detergent compositions do not undergo phase separation at room temperature for at least 6 months. Furthermore, they do not undergo phase separation when stored at 40–50 °C and / or refrigerated between 2–10 °C for at least 8 weeks (which also demonstrates the 6-month room temperature stability). As mentioned in this description, the absence of phase separation is confirmed by less than 5%, preferably less than 4%, separation of the detergent composition during the defined time period and under the specified temperature conditions. Source of alkalinity The liquid detergent composition comprises one or more sources of alkalinity. The source of alkalinity may be any source of alkalinity that is compatible with the other components of the detergent composition. Illustrative sources of alkalinity include alkali metal hydroxides, alkali metal carbonates, alkali metal silicates, alkali metal salts, phosphates, amines, and mixtures thereof, preferably alkali metal hydroxides including sodium hydroxide, potassium hydroxide, and lithium hydroxide or mixtures thereof, and most preferably sodium hydroxide and / or potassium hydroxide. Liquid detergent compositions may include a concentrate as well as a highly alkaline solution because they contain high amounts of alkaline sources. The alkalinity source controls the pH of the resulting solution when water is added to the detergent composition to form a solution. The pH of the solution must be maintained within the alkaline range to provide sufficient detergency. Furthermore, the pH of the solution is also useful for optimizing the reduction of germ counts, such as bacteria, fungi, viruses, and spores, in laundry washed with the detergent composition. The pH of the solution is between approximately 9 and approximately 14. More specifically, the pH of the solution is between approximately 10 and approximately 13.In a particularly preferred embodiment, the pH of the use solution is approximately 10.5 to approximately 12 and the pH of the concentrate is at least approximately 13 or higher. Suitable illustrative alkali metal hydroxides include sodium hydroxide, potassium hydroxide, and lithium hydroxide. However, sodium hydroxide is the most preferred. The source of alkalinity, preferably an alkali metal hydroxide, can be included in a variety of forms, including, for example, as solid beads, dissolved in an aqueous solution, or a combination of these. Alkali metal hydroxides are commercially available as granules or beads that have RQ / Qnn / Lznz / E / Yi a mixture of particle sizes, or as an aqueous solution, such as, for example, as approximately 45% by weight, approximately 50% by weight and approximately 73% by weight of solution. Illustrative alkali metal salts include sodium carbonate, trisodium phosphate, potassium carbonate, and mixtures of these. Illustrative phosphates include sodium pyrophosphate, potassium pyrophosphate, and mixtures of these. Illustrative amines include an alkanolamine selected from the group comprising triethanolamine, monoethanolamine, diethanolamine, and mixtures thereof. In some embodiments, the alkalinity source is included in the detergent composition in an amount of at least approximately 1% by weight to approximately 70% by weight, approximately 1% by weight to approximately 60% by weight, approximately 1% by weight to approximately 50% by weight, approximately 10% by weight to approximately 50% by weight, approximately 10% by weight to approximately 40% by weight, or approximately 20% by weight to approximately 40% by weight. Furthermore, without being limited according to the invention, all the cited ranges include the numbers defining the range and include every whole number within the defined range. Rheology modifiers The liquid detergent composition comprises a mixture of at least two rheology modifiers. The rheology modifiers include a mixture of alkali-swelling polymers (ASE) and hydrophobically modified alkali-swelling polymers (HASE). The rheology modifiers preferably also include an alkyl polyglycoside surfactant in addition to the ASE and HASE polymer rheology modifiers. HASEs may also be called hydrophobically modified alkali-soluble emulsion polymers and are referred to as such in this description. HASE polymers are synthesized from an acid / acrylate copolymer backbone and include an ethoxylated hydrophone manufactured by emulsion polymerization. See Acusol Rheology Modifier Product Specification (May 2008), Rhom and Haas, which is incorporated herein by reference in its entirety. Illustrative HASE polymeric rheology modifiers have the following formula: RQ / Qnn / Lznz / E / Yi where R is hydrogen or a C1-C6 alkyl group; where R1 is hydrogen or a C1-C6 alkyl group; where R2 is a suitable hydrophobic alkyl group in the range of C4 - C24, where the alkyl group may be alkoxylated, which may include ethoxylated, propoxylated, or a combination thereof, and the alkoxylation may be to a degree between 1 and 60, more preferably between 10 and 50; and where R3 may be any one of hydrogen or a C1-C6 alkyl group. The repeating units comprising R, Ri, R2, and R3 may be in any suitable order and may be randomly distributed. Suitable HASE polymers can have a molecular weight in the range of approximately 50,000 to approximately 500,000 g / mol, where the x:y ratio is in the range of approximately 1:20 to approximately 20:1, the x:w ratio is in the range of approximately 1:20 to approximately 20:1, and the x:z ratio is in the range of approximately 1:1 to approximately 500:1. Examples of commercially available HASE polymeric rheology modifiers according to the above formula are sold under the trade names Acusol 801S, Acusol 805S, Acusol 820, and Acusol 823. The preferred HASE polymeric rheology modifiers are sold under the trade names Acusol 805S and 820.In other embodiments, HASE polymeric rheology modifiers have a dynamic (absolute) viscosity range of approximately 30 cPs to 500 cPs, preferably approximately 40 cPs to 400 cPs, or more preferably approximately 100 cPs to 300 cPs. Additional HASE polymeric rheology modifiers may include, for example, polymers sold under the trade name Rheomer (e.g., Rheomer 33T) commercially available from Solvay, polymers sold under the trade name Novethix (e.g., Novethix L-10) commercially available from Lubrizol, polymers sold under the trade name Rheovis (e.g., Rheovis AT-120) commercially available from BASF, polymers sold under the trade name Optiflo HV80 commercially available from BYK, and polymers sold under the trade name Texicryl commercially available from Scott Bader. One or more HASE polymeric rheology modifiers can be included in detergent compositions. Beneficially, HASE polymeric rheology modifiers thicken through multiple mechanisms of action, including charge-induced polyelectrolytic chain expansion and association of extended hydrophobic groups. HASE polymers can be added directly to detergent formulations without the preparation of a separate thickener solution (i.e., premix). Viscosity is developed by anionicly charged, water-soluble inorganic bases or organic amines; these dissolve and swell due to charge-charge repulsion, thickening the formulation instantly. As the polymers swell, the dangling hydrophobic groups form associations within the formulation, such as with other polymers, surfactants, particles, emulsion droplets, and colorants.HASE polymers thicken through this type of associative structure. ASEs may also be called alkali-soluble emulsion polymers and are referred to as such in this description. ASE polymers are synthesized from acid and acrylate comonomers and are manufactured by emulsion polymerization. Illustrative ASE rheology modifiers have the following formula: RQ / Qnn / Lznz / E / Yi Jx and RQ J Qnn / L 7P7 / B / YIL where R and / or R1 is a hydrogen, CH3 or any alkyl chain from C1 to C6. Suitable ASE polymers may have a molecular weight in the range of approximately 20,000 to approximately 300,000 g / mol, and where the x:y ratio is in the range of 1:10 to 10:1. Examples of commercially available polymeric ASE rheology modifiers according to the above formula are sold under the trade names Acusol 810A, Acusol 830, Acusol 835, and Acusol 842. A preferred polymeric ASE rheology modifier is sold under the trade name Acusol 830. In other embodiments, the polymeric ASE rheology modifiers have a dynamic (absolute) viscosity range of approximately 10 cPs to 600 cPs, preferably approximately 100 cPs to 500 cPs, or more preferably approximately 150 cPs to 450 cPs. Additional ASE rheology polymer modifiers may include, for example, polymers sold under the trade name Rheovis (e.g., Rheovis AS-1125) commercially available from BASF, and polymers sold under the trade name Texicryl commercially available from Scott Bader. Detergent compositions may include one or more ASE polymeric rheology modifiers. Advantageously, ASE polymeric rheology modifiers can be added directly to detergent formulations without preparing a separate thickener solution (i.e., premix). Viscosity is developed by adjusting the pH with the alkalinity source, as the polymers contain carboxylic groups that swell upon neutralization. Not tied to a specific mechanism of action, the polymers thicken via a non-associative mechanism (i.e., they do not interact with insoluble surfactant structures, particles, or emulsion droplets). ASE polymers thicken through chain entanglement in the continuous phase. In one respect, rheology modifiers include alkyl polyglycoside surfactants. Suitable alkyl polyglycosides include, but are not limited to, alkyl polyglycosides. Alkyl polyglycosides are bio-based, non-ionic surfactants with thickening, wetting, and detergent properties. Commercially available alkyl polyglycosides may contain a mixture of carbon chains. Illustrative alkyl polyglycosides include alkyl polyglycosides containing carbon chains shorter than C16. For example, suitable alkyl polyglycosides include C8-C16 alkyl polyglycosides and mixtures of alkyl polyglycosides containing primarily C8-C16 or C12-C16 alkyl polyglycosides. Suitable commercially available alkyl polyglucosides include Glucopon 625 UP available from BASF Corporation.In some embodiments, the alkyl polyglycoside surfactant is included in the detergent composition in an amount of at least approximately 0.01 wt% to approximately 5 wt%, approximately 0.1 wt% to approximately 5 wt%, approximately 0.1 wt% to approximately 3 wt%, approximately 0.1 wt% to approximately 1 wt%, or approximately 0.1 wt% to approximately 0.5 wt%.

Furthermore, without being limited according to the invention, all the cited ranges include the numbers defining the range and include every whole number within the defined range. In some embodiments, the detergent compositions include an active amount of rheology modifiers ranging from approximately 0.5% to approximately 5%, from approximately 1% to approximately 3%, and from approximately 1.4% to approximately 1.8%. Furthermore, without being limited according to the invention, all the cited ranges include the numbers defining the range and include every whole number within the defined range. In some embodiments, the ratio of the HASE rheology modifier to the ASE rheology modifier is from approximately 0.1:1 to approximately 10:1, preferably from approximately 0.5:1 to approximately 5:1, or from approximately 0.5:1 to approximately 2:1. Furthermore, without being limited according to the invention, all cited ranges include the numbers defining the range and include every whole number within the defined range.

Optical brighteners Optical brighteners may also be included in detergent compositions. Optical brighteners are also called fluorescent whitening agents or fluorescent brightening agents. Brighteners are added to laundry detergents to replace the bleaching agents washed away during washing and to make clothes appear cleaner. Optical brighteners may include dyes that absorb light in the ultraviolet and violet region (typically 340–370 nm) of the electromagnetic spectrum and re-emit light in the blue region (typically 420–470 nm). These additives are often used to enhance the color appearance of a textile material, causing a perceived whitening effect by making materials appear less yellow by increasing the total amount of reflected blue light. In some formulations, optical brighteners are included in the compositions in an amount of approximately 0.1 to approximately 5% by weight, from approximately 0.15 to approximately 3% by weight, or from approximately 0.2 to approximately 2% by weight. Examples of suitable commercially available optical brighteners that will be appreciated by those skilled in the art include stilbene derivatives, pyrazoline, carboxylic acids, methynocyanines, dibenzothiophene-5,5-dioxide, azoles, 5- and 6-membered ring heterocycles, and various other agents. Examples of suitable commercially available optical brighteners include those sold under the trade name Tinopal, available from BASF. Examples of optical brighteners are also described in *The Production and Application of Fluorescent Brightening Agents*, by M. Zahradnik, published by John Wiley & Sons, New York (1982), and in U.S. Patent No. 9,752,109, both of which are incorporated herein by reference. Aesthetic-enhancing agents, such as colorants and perfumes, are also optionally incorporated into detergent compositions. Examples of perfumes or fragrances useful in acidic cleaning compositions include, but are not limited to, liquid fragrances. It should be understood that the water supplied as part of the detergent solution or concentrate may be relatively free of hardness. The water is expected to be deionized to remove most of the dissolved solids. Subsequently, the concentrate is diluted with water available at the dilution site, and this water may contain varying levels of hardness depending on the location. Although soft or deionized water is preferred for formulating the concentrate, it can be formulated with water that has not been deionized. That is, the concentrate can be formulated with water containing dissolved solids and can be formulated with water that may be characterized as hard water. RQ / Qnn / Lznz / E / Yi Manufacturing methods Advantageously, detergent compositions can be manufactured using simple liquid batching processes. As an added benefit, the batching process does not include a premix, granulation stage, and / or homogenizer for the formulation. Furthermore, detergent composition formulations can exceed the maximum viscosities that would require additional energy input and / or changes to processing machinery as a result of batching processes that introduce both rheology modifiers (e.g., HASE / ASE polymers) and surfactants to the batch before the alkalinity source. As demonstrated herein, the stability of the detergent composition is affected by the ability of the surfactants to interact with the rheology modifiers before the alkalinity is added to the batching process.Following this process provides stable detergent compositions, so the emulsions are stable. Stable compositions are opaque emulsions where the liquid composition is stable for at least 6 months at room temperature (or measured under accelerated stability conditions of 50°C for 8 weeks), and where stability is measured according to a phase separation of less than 5%. Beneficially, stable emulsions do not experience phase separation, or only minimal separation, during storage or when exposed to widely varying temperatures. Methods of use Detergent compositions are suitable for a variety of applications. Laundry detergents are a particularly preferred application. However, additional cleaning applications can be used where a rheology modifier package is needed to provide formed detergent formulations containing nonionic surfactants and sources of alkalinity and / or enhancers. For example, detergent compositions can be used for hard surface cleaning, membrane cleaning, paper processing and / or water treatment, and various laundry applications. It is desirable that the detergent compositions be evenly distributed using conventional dispensers, such as pumps, due to the rheology modifier package employed. Detergent compositions can be applied to surfaces using a variety of methods. These methods can operate on an object, surface, or the like by bringing the object or surface into contact with the detergent composition. Such contact can comprise any of the numerous methods for applying a viscous liquid, such as pumping the composition for later use and / or diluting a concentrate, immersing the object in the composition, treating the object with foam or gel using the composition, or a combination thereof. Without being limited to contact according to the invention, a concentrate or liquid composition for use can be applied to or come into contact with an object by any conventional method or apparatus for applying a viscous liquid composition to an object.For example, the surface can be cleaned with, sprayed with, foamed and / or immersed in the liquid compositions, or liquid compositions made from the liquid compositions can be used. RQ / Qnn / Lznz / E / Yi concentrated. Liquid compositions can be sprayed, foamed, or applied to a surface; the compound can be made to flow onto the surface, or the surface can be immersed in the compound. Contact can be made manually or by machine. Detergent compositions are in contact with a surface or object for a sufficient amount of time to clean it. In one aspect, the surface or object is in contact with the detergent composition for at least approximately 1 minute or at least approximately 10 minutes. Detergent compositions can be applied as a ready-to-use solution or in concentrated form to a surface or object requiring cleaning.

RQ / Qnn / Lznz / E / Yi The formulations were evaluated for viscosity, stability, and formulation separation. Viscosity was determined by QATM 084 using the Glass Jar Stability Test as follows: The samples were placed in several glass jars / vials and stored at room temperature, 40 °C, and 50 °C. At different time points, stability was assessed by evaluating appearance (color, visible separation, other observations) and measuring the percentage of separation, if any. The percentage of separation was determined by measuring the height of the separated layer (typically an opaque layer at the bottom) and the total sample height. The formula for the calculation is shown: % separation = (height of the lower layer (mm) / height of the sample (mm)) * 100% The percentage of separation was measured at 1 week, 5 weeks, and 9 weeks for each sample under the different storage conditions. As shown on the y-axis of Figures 1-2, as the percentage of separation increases, the emulsion becomes less stable. The results show that when the nonionic alkyl polyglycoside surfactant Glucopon is included in the formulations, there is a greater capacity to increase the amount and ratio of HASE polymer to ASE. As shown, the presence of Glucopon increased the stability of the 2:1 HASE:ASE formulations, while formulations without Glucopon showed the best stability with a 1:1 HASE:ASE formulation. As shown in Table 3, viscosity generally increases as the HASE:ASE ratio increases. This demonstrates a preference for formulations containing all three rheological polymers and for blends with higher concentrations of HASE:ASE polymers that also include Glucopon. Results that have a separation percentage of less than approximately 5%, and preferably from approximately 0% to approximately 2%, are preferred formulations. EXAMPLE 2 The mixing order of the key components is shown to impact the stability and viscosity of the formulation. This was demonstrated by preparing batches with the same chemical composition (Table 4) but with the key components added in different mixing orders. The key components were divided into rheology modifiers, nonionic surfactants, and sodium hydroxide. The batches were made using six different mixing orders, and of these, the product was only stable when both rheology modifiers (e.g., HASE / ASE polymers) and surfactants were added to the batch before the NaOH alkalinity. This indicates that stability is affected by the ability of the surfactants to interact with the rheology modifiers before the addition of the alkalinity.

This viscosity range allows the products to be poured and pumped, which is desirable for various applications. In one example (Table 6), the addition of hexylene glycol to the formulation resulted in a higher final product viscosity. Furthermore, the addition of hexylene glycol also resulted in a lower peak viscosity during mixing, which facilitates manufacturing. Viscosity measurements are shown in Table 7. TABLE 6 Raw Material Description Formula A Formula B Water 42.8 37.8 Hexylene Glycol - 5 HASE / ASE Rheology Modifier Mixture 5 5 Alcohol Ethoxylate Surfactant(s) 26 26 Sodium Hydroxide 15 15 Other 11.2 11.2 RQ / Qnn / Lznz / E / Yi TABLE 7 AB Formulation Peak viscosity in process 4480 cPs 3280 cPs Final viscosity (ambient storage) 1140 cPs 2316 cPs Viscosity was measured at each material addition and after a final 90:00 mix. Viscosities were measured using a Brookfield RVT, spindle #3, at 50 rpm. As shown in Table 6, the inclusion of the hydrotrope has a significant impact on the viscosity of the final liquid product and on the peak viscosity measurement. Using the ASE / HASE polymer ratio of 1:1 in the formulation results in a more desirable viscosity with the use of the hexylene glycol hydrotrope. In one embodiment, the addition of hexylene glycol (or other hydrotropes, e.g., dipropylene glycol) before the addition of the caustic beneficially provides a lower peak viscosity in the mixing phase and results in a more stable product.
