Description

[0001] Cross-references to related applications This application claims the benefit of priority to U.S. Provisional Patent Application No. 63 / 609,515, filed December 13, 2023, the contents of which are hereby incorporated herein by reference in their entirety. Background Technology

[0002] Cleaning compositions, such as light-duty cleaning compositions, floor cleaners, and disinfectant products, can be used to clean a wide variety of surfaces, including hard surfaces. Exemplary hard surfaces include surfaces commonly found in kitchens and bathrooms, ranging from floors, toilets, sinks, and work surfaces to pots and pans. Such cleaning compositions can be formulated into solid, liquid, or gel forms, but are typically used in liquid form (e.g., aqueous liquids). Cleaning compositions typically include one or more surfactants, which can be nonionic, anionic, cationic, or amphoteric surfactants. One or more surfactants can act as emulsifiers, foaming agents, detergents, solubilizers, and wetting agents in the cleaning composition. While it is common practice to include mixtures or combinations of various surfactants in cleaning compositions, it remains difficult to predict the effects that may result from combining various surfactants due to the significant differences in the chemical structure of each individual surfactant. For example, complexes formed between surfactants with different chemical properties may often produce compositions that are unstable and / or form precipitates, making them undesirable to consumers.

[0003] For cleaning products or compositions, such as floor cleaners, stability (e.g., clarity and uniformity) and viscosity are important factors influencing consumer perception. Consumers expect the desired viscosity to be neither too thick nor too thin, and the product or its composition should be visually appealing in terms of clarity. Other factors consumers consider when choosing cleaning products or compositions include cleaning efficacy or performance and foam generation. Cleaning performance can be improved by enhancing the cleaning composition's ability to emulsify oils. While improved foam generation is not directly related to improved cleaning performance, it provides a visual cue that gives consumers the impression or perception of improved cleaning performance. Therefore, it may be desirable for flash foam, or foam generated during agitation, to be initially stable and relatively large in volume before decreasing to an appropriate level.

[0004] Fragrance is also a key performance characteristic of cleaning compositions. When consumers compare two cleaning products with the same base formula but different fragrances (such as dilutable detergents in containers), they typically rate the product with a more pleasant fragrance as a better cleaner. Consumers may also rate products with a stronger and / or longer-lasting fragrance as better cleaners.

[0005] Furthermore, providing sustainable products is rapidly becoming an important consumer demand. For example, products that use less plastic, less water, and / or save space benefit both consumers and the environment. One way to provide sustainable products is to offer concentrated compositions that consumers can easily dilute with water. However, water-based cleaning compositions typically use thickening polymers to provide the appropriate viscosity, and unfortunately, formulating concentrated compositions with thickening polymers has always been difficult due to the relatively high viscosity of concentrates. As a result, reconstituted compositions often exhibit poorer physicochemical properties.

[0006] However, concentrated cleaning products can be used in a variety of ways, including direct application to surfaces or cleaning tools (such as sponges or cloths) and indirect addition to water in the form of dilutable detergents in containers. Concentrated cleaning products can reduce the use of plastic containers, promote the recycling and reuse of plastic containers, and reduce the overall carbon footprint.

[0007] Given the foregoing, there is a need for improved, reasonably priced concentrated home care products with acceptable viscosity, fragrance, stability, and cleaning efficacy. Summary of the Invention

[0035] Any member of the list of species used to exemplify or define a genus may be different from, overlap with, be a subset of, be equivalent to, or be nearly identical to, any other member of the list of species. Furthermore, unless explicitly stated otherwise, the list of species used to define or exemplify a genus is open when describing the Markush Formation, provided that other species may exist that define or exemplify the genus as well as or better than any of the other species listed.

[0036] The phrases "mixtures thereof," "combinations thereof," or "combinations of two or more" do not require that the mixture include all of A, B, C, D, E, and F (but may include all of A, B, C, D, E, and F). Rather, the indication may include any two or more mixtures of A, B, C, D, E, and F. In other words, this is equivalent to the phrase "one or more elements selected from the group consisting of A, B, C, D, E, F, and any two or more mixtures of A, B, C, D, E, and F." Similarly, the term "salts thereof" also refers to "salts thereof." Therefore, in the case where this disclosure relates to "elements selected from the group consisting of A, B, C, D, E, F, their salts, and mixtures thereof," the indication may include one or more of A, B, C, D, and F, may include one or more of salts of A, B, C, D, E, and F, or may include mixtures of any two of A, B, C, D, E, F, salts of A, B, C, D, E, and F.

[0037] All components and elements actively described in this disclosure may be excluded negatively from the claims. In other words, the cleaning compositions of this disclosure may be free of or substantially free of all components and elements actively described throughout this disclosure. In some cases, the cleaning compositions of this disclosure may be substantially free of non-accidental amounts of the ingredients or compounds described herein. A non-accidental amount of an ingredient or compound refers to the amount of said ingredient or compound added alone to the cleaning composition. For example, a cleaning composition may be substantially free of non-accidental amounts of an ingredient or compound, although such an ingredient or compound may be present as part of a raw material included as a blend of two or more compounds.

[0038] Some components among the various categories of components identified may overlap. In such cases where overlap is possible and the cleaning composition comprises two components (or the composition comprises more than two overlapping components), the overlapping compound does not represent more than one component. For example, some compounds can be characterized as both pH adjusters and antimicrobial agents. If a particular cleaning composition comprises both a pH adjuster and an antimicrobial agent, then the particular compound will function only as either a pH adjuster or an antimicrobial agent, not both.

[0039] For readability purposes, chemical functional groups are presented in their adjective form; for each adjective, the word "group" is assumed to be used. For example, the adjective "alkyl" followed by a noun should be interpreted as "alkyl group".

[0040] The aqueous cleaning compositions disclosed herein may be or include cleaning products. For example, the aqueous cleaning compositions may be cleaning products comprising a cleaning composition and / or one or more additional ingredients / components. As used herein, the term "cleaning product" may refer to the final form sold to the consumer.

Therefore, the cleaning compositions of the present invention can form part or base of hard surface cleaners, spray cleaners, floor cleaners, microwave oven cleaners, stovetop cleaners, oven cleaners, etc., or combinations thereof, incorporated therein, and / or used as said hard surface cleaners, spray cleaners, floor cleaners, microwave oven cleaners, stovetop cleaners, oven cleaners, etc., or combinations thereof. As used herein, the term "tableware" refers to tableware and other tools and utensils related to food preparation and / or consumption.

[0042] The cleaning compositions disclosed herein may be aqueous cleaning compositions. Aqueous cleaning compositions may include an aqueous matrix or carrier, a surfactant system comprising one or more surfactants, one or more viscosity modifiers, one or more excipients, or combinations thereof. Aqueous cleaning compositions may be formulated to exhibit a visible, clear, or opaque and homogeneous appearance upon exposure to aging or cooling conditions (e.g., about 5°C). For example, an aqueous cleaning composition may include multiple surfactants and / or viscosity modifiers in relatively formulated amounts to provide an opaque and homogeneous composition upon exposure to aging or cooling conditions.

[0043] Aqueous cleaning compositions can be formulated to have a pourable viscosity in undiluted and / or diluted form. For example, the viscosity of an aqueous cleaning composition measured at about 25°C can be from about 500 cP to about 2,000 cP. For example, the viscosity of an aqueous cleaning composition measured at about 25°C can be about 500 cP, about 600 cP, about 700 cP, about 750 cP, about 800 cP, about 850 cP, or about 900 cP to about 950 cP, about 1,000 cP, about 1,100 cP, about 1,200 cP, about 1,300 cP, about 1,600 cP, about 1,800 cP, or about 2,000 cP. In another example, the viscosity of the aqueous cleaning composition, measured at about 25°C, may be about 500 cP to about 2,000 cP, about 500 to about 1,500 cP, about 500 cP to about 1,200 cP, or about 500 cP to about 950 cP.

[0044] The surfactant system can be configured to facilitate the removal of stains, dirt, oil, debris, grease, etc., from surfaces. The surfactant system may include a variety of surfactants, including one or more anionic surfactants, one or more nonionic surfactants, or combinations thereof.

The surfactant system may also be able to provide or be configured to offer: a relatively low cloud point, improved stability, increased flash foaming, improved oil emulsification, improved contact angle on soiled surfaces, improved soap scum removal efficacy, improved degreasing efficacy, improved residue removal efficacy, or combinations thereof. For example, each of the various surfactants in the surfactant system may be varied or modified (e.g., increased or decreased) relative to weight ratio and / or concentration to provide: a relatively low cloud point, improved stability, increased flash foaming, improved oil emulsification, improved contact angle on soiled surfaces, improved soap scum removal efficacy, improved degreasing efficacy, improved residue removal efficacy, or combinations thereof.

[0079] Example The examples and other embodiments described herein are exemplary and are not intended to limit the scope of the compositions and methods described herein. Equivalent changes, modifications, and variations in specific embodiments, materials, compositions, and methods can be made within the scope of this disclosure to obtain substantially similar results.

[0080] Example 1 – Cleaning ingredients Table 1 below describes three water-based cleaning compositions. The first is a conventional strength product, while the second is a 10× concentrated formulation that does not contain the viscosity modifiers Pronique L-44 and SD alcohol 40B. The third is a water-based cleaning composition with a 10× concentration (compared to Formulation A) and further contains the viscosity modifiers Pronique L-44 and SD alcohol 40B.

[0081] Table 1 – Cleaning Composition Formulation Implementation 2 – Cleaning the preparation materials Various aqueous cleaning composition formulations were prepared as disclosed in Table 2 below.

[0082] Table 2 – Cleaning Composition Formulations Next, a formulation similar to Formulation 3 (matrix) but with twice the surfactant concentration (2×) was prepared and designated Formulation 3a. Formulation 4 (10×) was diluted to a surfactant concentration of 1× and designated Formulation 4a. Formulation 2 (deep cleaning) was diluted to 1 / 4 and 1 / 8 strength, respectively, and designated Formulation 2a and Formulation 2b, respectively. In summary, eight formulations (1, 2, 2a, 2b, 3, 3a, 4, and 4a) were prepared, and their degreasing performance, soap scum removal, residue removal, and foaming properties were tested, as discussed in the examples below.

[0083] Example 3 – Degreasing Performance The degreasing properties of the eight formulations disclosed above in Example 2 were evaluated. Grease is a type of stain that can be difficult to remove due to its hydrophobicity, high interfacial tension with water, and high affinity for hard surfaces such as Formica. The purpose of the tests described herein is to quantitatively determine the percentage of effectiveness of the formulations when cleaning white Formica tiles stained with grease with a sponge containing the above-described formulations applied thereto.

[0084] The test grease contained 79.9% cyclohexane solvent, 15% tallow, 5% hydrogenated grease, and 0.10% red dye. White Formiga tiles (n = 24) were used for each test preparation. The tiles were cleaned with alcohol and paper towels, and initial measurements were taken with a spectrophotometer (Byk-Gardner Spectroguide) before staining, averaging three readings at each quarter-point of the tile. The tiles were then stained with the dyed grease, using a roller device to spread the grease evenly on the tile, and then allowed to dry.

[0085] Next, apply 3.0 mL of the test formulation to a sponge and spread the product evenly. Set the abrasive device to apply the product to the tile at a weight of 100 g to provide appropriate pressure for 5 wipings. Then rinse the tile with tap water and allow it to dry at room temperature. Measure the dried tile using a spectrophotometer and calculate the degreasing efficiency percentage using the following formula: The results are shown in Table 3 below.

[0086] Table 3 – Percentage of Efficacy of Cleaning Compounds like Figure 1 As shown, formulation number 4, with a 10× concentration and a thickener, effectively removed grease. When used undiluted, there was no significant difference in degreasing efficacy between formulations number 1 (antibacterial), number 2 (deep cleaning), and number 4 (10×). When formulation number 1 was diluted to the same strength as formulation number 3 (1× concentration), it exhibited better performance, comparable to formulation number 3a (2× concentration).

[0087] Example 4 – Soap Scum Removal As described in Table 2 of Example 2, eight formulations were used to evaluate soap scum removal. Soap scum is a white, powdery residue of dirt, soap, and mineral deposits that may appear as a white or gray film covering the surfaces of showers, sinks, and bathtubs. Soap scum forms when the fatty oils or grease-based components of soap react with magnesium stearate and calcium stearate minerals in water. In this example, black ceramic tiles were soiled with artificial soap scum, and the percentage of effectiveness in removing soap scum was quantitatively determined by cleaning with a cleaning formulation applied to a sponge.

[0088] In this example, the soap scum mixture contained 86.81% ethanol, 5% calcium stearate, and 8.19% deionized water. Black ceramic tiles (n=24) were used for each test formulation. The tiles were cleaned with alcohol and paper towels, and initial measurements were taken with a spectrophotometer (Bick-Gartner spectrally guided) before soiling, averaging three readings at each quarter-point of the tile. The tiles were then stained with the soap scum residue, using a roller to spread the residue evenly over the tile, and then allowed to dry.

[0089] Next, apply 2.5 mL of the test formulation to a sponge and spread the product evenly. Set the abrasive device to apply the product to the tile and wipe 30 times. Then rinse the tile with tap water and allow it to dry at room temperature. Measure the dry tile with a spectrophotometer and calculate the percentage of soap scum removal efficiency using the following formula: The results are shown in Table 4 below.

[0090] Table 4 – Percentage of Soap Sludge Removal Efficacy like Figure 2 As shown, formulation 4 removes soap scum, and except for formulation 2b, it does not show a significant difference in soap scum removal compared to the other formulations.

[0091] Example 5 – Residue Removal The residue removal efficacy of various cleaning formulations was evaluated. When cleaning surfaces, streaks typically arise from a combination of potential residues in the cleaning formulation and existing dirt on the surface. Although residues or streaks can be detected by the human eye, this visual evaluation depends on reflection and the time it takes for light to be reflected from the surface. If the surface is smooth and glossy (e.g., glass or polished metal), light will be reflected at the same angle as it was incident on the surface; this is called specular reflection. In contrast, diffuse reflection refers to light hitting an object and being reflected in multiple different directions. This can occur when the surface is rough and less smooth. In this example, the residue left after cleaning the surface was quantitatively evaluated using a scale of 1 to 10, where 0 indicates a significant amount of residue and 10 indicates no significant residue.

[0092] Because wiping surfaces with a cloth often produces streaks, a pad was replaced with a stirrer from a mechanical kitchen robot to simulate this. A cloth soaked in the test formulation was then attached to the pad, and a wiping simulation was performed on the surface. After the surface dried, a trained evaluator assessed the presence of streaks. Black polymethyl methacrylate (PMMA) tiles (n=4). In this example, the seven formulations tested included formulation #1 (antibacterial), formulation #2 (deep cleaning), formulation #3 (substrate), formulation #3a (2×substrate), formulation #4 (10× concentration), formulation #4a (10× diluted to 1×), and a dilution of formulation #3 (substrate) to 10% (hereinafter referred to as formulation #3b). A placebo was also tested. The results are shown in Table 5 below.

[0093] Table 5 – Residue Removal Efficiency like Figure 3 As shown, formulation number 4 leaves more residue than the other formulations, but there is no significant difference between formulation number 4 and formulation number 2. Furthermore, formulation number 4a leaves less residue than any of formulations number 1, 2, or 4.

[0094] Example 6 – Foam Characteristics The foam characteristics of various cleaning formulations were evaluated to determine foam formation and further collapse in pure and diluted formulations. Some formulations are based on highly foaming anionic surfactants. These highly foaming anionic surfactants may be able to maintain sufficient foam levels throughout the cleaning process and have sufficient emulsifying power to handle different oily stains. Foams are known to contain a high volume fraction of gas dispersed in a liquid, where the liquid forms a continuous phase. “Wet” foams with high water content, such as those immediately after foam formation, may have more or less spherical bubbles. To generate foam, the surface of the liquid film is often stabilized by a layer of surfactants, polymers, and / or particles. In this example, the characteristics and behavior of foams generated by induced oscillation in a cylinder containing various cleaning formulations were evaluated.

[0095] The following formulations (as illustrated in Example 2) were evaluated: formulation No. 1, formulation No. 2, formulation No. 2 diluted to a final concentration of 3.0% (hereinafter referred to as formulation No. 2c), formulation No. 3, formulation No. 3a, formulation No. 4, and formulation No. 4a.

[0096] Using 300 ppm hard water as a diluent, a 2.5% concentration of the test sample was prepared. The samples were randomized to account for the four locations of the foam shaker, ensuring that each formulation was tested at every location on the shaker. 100 mL of the formulation to be tested was added to the test tube, and the test tube was shaken in the foam shaker at 30 RPM (40 shakes). The equipment was stopped, and the foam volume was measured (i.e., time equal to zero). The foam volume was then measured once per minute over six minutes, for a total of 7 measurements.

[0097] For formulations 2 and 2c, the foam volume measured for each sample was 400 mL; and for formulation 4, the foam volume measured for each sample was 0 mL. The results for formulations 1, 3, 3a, and 4a are shown in Table 6 below.

[0098] Table 6 – Foam Volume of Cleaning Compounds like Figure 4 As shown, during the test, the foam generated by formulations 2 and 2c, as well as formulation 1, remained stable. Formulation 4 did not generate foam, and the foam generated by formulation 4a decreased continuously during the test.

[0099] Example 7 – Fragrance Evaluation As described in Example 2, the fragrances of various lavender-scented cleansing blends, including blend number 3, blend number 3a, and blend number 4, were evaluated. The fragrances were evaluated on a scale of 1 to 5, as follows: 1 = very low strength; 2 = low strength; 3 = medium strength; 4 = high strength; and 5 = very high strength. The fragrances were measured at 0 hours, 2 hours, 6 hours, and 24 hours. Dilutes of each blend were prepared as either 1× (60 g blend / 1 gallon of water) or 10× (6 g blend / 1 gallon of water). The results are shown in Table 7 below.

[0100] Table 7 – Properties of Fragrances As shown in Table 7, formulation number 4 showed significantly higher performance both initially and over time, including at 24 hours.

[0101] Example 8 – Micro-robustness and Acceleration Stability Micro-robustness and accelerated stability tests were performed on formulation number 4 as described in Example 2 above. For the micro-robustness test, it was determined that the sample containing lavender and lemon fragrances of formulation number 4 met or exceeded the threshold micro-robustness index > 0.85.

[0102] For stability testing, the pH, turbidity, color, odor, and appearance of formulation 4 (lavender and lemon samples) were monitored at 0, 1, and 2 weeks. The results are shown in Table 8 below. Both formulations passed the stability test.
