Description

Attorney Docket No. 1116015-00-WO-01-HCSPRAY CLEANSING COMPOSITIONS AND METHODS FOR THE SAMECROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of priority from U.S. Provisional Patent Application No. 63 / 753,143, filed 3 February 2025, the contents of which are hereby incorporated herein by reference in its entirety.BACKGROUND

[0002] In formulating home care cleansing compositions, a need exists to manufacture an easily used composition having excellent soil, e.g., grease, removal properties and controlled foaming. In traditional hand dishwashing, a user often will apply a gel or thick liquid cleansing composition to a sponge or scrubber and apply the sponge or scrubber to the dish. This can result in applying an excess of the cleansing composition to the dish, exerting additional effort to manually scrub the dish, and / or additional use of water to rinse the cleansing composition from the dish.

[0003] In order to reduce or eliminate certain of these potential drawbacks, cleansing compositions for use in hand dishwashing may be applied through the use of a spray bottle. Nonetheless, it remains challenging to formulate a dishwashing liquid suitable for use in a spray bottle that does not clog the trigger of the spray bottle, delivers a sufficient amount of the cleansing composition to the dish surface, and also improves grease removal while maintaining stability (e. ., clarity and homogeneity) of the composition.

[0004] What is needed, then, are improved cleansing compositions that provide superior cleansing performance and are suitable for application via spraying, e.g., from a spray bottle.BRIEF SUMMARY

[0076] Four aqueous cleansing compositions as shown below in Table 1 were tested. The formulations of Comparative Composition 1, Comparative Composition 2, Test Prototype A, and Test Prototype B are set forth in Table 1.

[0077] Table 1 - Cleansing CompositionsAttorney Docket No. 1116015-00-WO-01-HC

[0078] IKW Test Soil 1 was prepared as described in Nitsch, Ch. & Huttman, G., Recommendation for the Quality Assessment of the Cleaning Performance of Hand Dishwashing Detergents, SOFW Journal 2002, 128(5): 11- 15. Briefly, using hot water, the fat components were melted in a beaker in the microwave or in a water bath. To avoid splattering, the container was covered. A coloring agent, milk powder, flour, and water were stirred into the melted fat mixture (50-60 °C). The mixture was then stirred thoroughly (e.g., for a 1 kg batch using a Braun Electronic Mixer) in order to obtain a homogenous test soil. After preparation, the test soil was divided into portions as necessary, frozen for at least 12 hours (-18 °C or colder), and then defrosted either overnight in a refrigerator (approximately 4 °C) or directly in a water bath. The test soil should be used portion by portion, and portions should not be mixed together. The test soil can be stored for 12 weeks in a deep freezer. Thawed test soil should not be refrozen.

[0079] Trigger comparison of foam consistency: A watery foam is considered less desirable, compared to a foam with small bubbles and less water. To test foam consistency with different triggers, a control composition, Comparative Composition 1, Prototype A, and Prototype B as listed above in Table 1 were each tested with (1) an AFA® brand wide trigger (prolonged dispensing trigger); and (2) a BERRY® Booster brand trigger (pre-compressed dispensing trigger), applying 3 shots of each into a metal pan. The results demonstrated that Prototype B withAttorney Docket No. 1116015-00-WO-01-HCthe AFA® trigger was superior in foam consistency to any of the tested composition / trigger combinations.

[0080] Degreasing without scrubbing: Pans were stained with 2 g of IKW Test Soil 1 and baked for 5 minutes at 160 °C. The pans were then placed in an upright position. A control composition, Comparative Composition 1, Prototype A, and Prototype B as listed above in Table 1 were each placed into a spray bottle (where Prototype A used the BERRY® trigger and Prototype B used the AFA® trigger), and the trigger was activated at a distance of 30 cm from the pan. The test was carried out with 3 shots into each pan, trying to completely cover the surface. The product was left on the surface for one minute and then rinsed with tap water at room temperature. The trigger was used to apply the water by spraying to rinse. Finally, degreasing was measured by visual comparison of each pan. It is noted that the degreasing performance may differ based on the mode of testing or the recipe of the test soil. The results demonstrated that Prototype B had more degreasing without scrubbing than any of the other 3 compositions tested.

[0081] Foam adherence: Metal (stainless steel) tile was used for testing foam adherence. The total surface of the tile was covered with the IKW Test Soil 1, and the surface was divided into four spaces in order to test the spray samples. Five shots were applied to each space to completely cover the stain with the tested compositions (a control composition and Comparative Composition 1, Prototype A, and Prototype B described in Table 1 above). All of the Comparative Composition 2, Prototype A, and Prototype B were sprayed using the BERRY® trigger. The tested compositions were left on the surface for 3 minutes. A photograph was taken at the beginning and the end to visually compare the foams for each of the four tested compositions. The results demonstrated that Prototype A foam lasting was similar to but slightly better than Prototype A.

[0082] Foam lasting after scrubbing: Metal (stainless steel) tile was used for testing foam lasting / duration. Pans were stained with 2 g of IKW Test Soil 1 and baked for 5 minutes at 160 °C. The test was earned out with 3 shots into each pan, and then the pans were scrubbed 10 times using a SCOTCH BRITE® sponge that had been previously wet with tap water at room temperature. The sponge was pushed in order to leave all of the foam on the surface of the pan.

[0083] Foam area: To evaluate the foam area, each formulation (a control composition and Comparative Composition 1, Prototype A, and Prototype B described in Table 1 above) was applied using 1 spray from the trigger into a pan from a distance of 30 cm. Prototype A and Prototype B were each sprayed using the BERRY® trigger and the AFA® trigger. The diameterAttorney Docket No. 1116015-00-WO-01-HCof the foam generated was then measured, wherein the diameter of the foam is considered directional to the foam area. The results demonstrate that, using the BERRY® trigger, both Prototype A and Prototype B delivered more foam area than either the control or Comparative Composition 1. With the AFA® trigger, Prototype A, Prototype B, and Comparative Composition 1 delivered less foam area than the control.

[0084] Contact angle: Each of the compositions (a control composition and Comparative Composition 1, Prototype A, and Prototype B described in Table 1 above) was evaluated for contact angle measurement. Measurement of the contact angle of a drop of the composition was performed on a flat surface using the Drop Shape Analyzer DSA25 (Kriiss), where beef tallow colored with Sudan Red was soiled on a melamine tile. The lower and faster the contact angle is reduced, the better the wetting of a soiled surface, which can also be an indicator of better cleaning performance of the soiled surface.

[0085] Measurements were carried out at room temperature, and samples were tested without dilution in triplicate for 100 seconds. The means were then plotted, and the results are shown in Figure 1. As shown, the contact angle of Prototype B dropped lower and faster than any of the other three tested compositions.Example 2

[0086] It may be necessary or desirable, for example in cold weather climates, to prepare cleaning compositions such as dish sprays using cold water. The use of cold water (e.g., less than 15 °C), however, for manufacturing cleansing compositions is known to cause turbidity, as it reduces the solubility of certain ingredients. It would be desirable therefore to manufacture a clear or less turbid composition using cold water, without suffering form undue turbidity.

[0087] Prototype A and Prototype B as described above were manufactured, varying the order of addition of citric acid and the temperature of the water. The pH and appearance was monitored and turbidity (NTU) was tested with a HACH Turbidimeter 2100Q. Samples were put overnight in a freezer and then thawed to evaluate appearance recovery after a freeze / thaw cycle.

[0088] The results demonstrated that both Prototype A and Prototype B, when above pH 11, were opaque. Both Prototype A and Prototype B, when below pH 11, were clear, regardless of the water temperature with which the compositions were prepared. The results indicate that to control the final appearance of the cleaning compositions, the pH adjustment is more relevant than the water temperature.Attorney Docket No. 1116015-00-WO-01-HC

[0089] When citric acid was added at the beginning of the manufacturing process, the prototypes remained clear during the entire manufacturing process and afterwards. When citric acid was added later in the manufacturing process, the appearance of the prototypes was opaque up to the addition of citric acid (which also lowers the pH). All of the samples tested resulted in translucent clear compositions after manufacture and also following the overnight freeze / thaw cycle. The results are shown in Figure 2 and in Table 2 below.

[0090] Table 2 - pH and Temperature Impact on Appearance of Prototypes A and BExample 3

[0091] A study was conducted to evaluate the effects of pH on turbidity using citric acid and lactic acid. Prototype A as described above in Example 1 was prepared using either citric acid or lactic acid to adjust the pH, and the turbidity (NTU) was measured. The results are shown in Figure 3. As shown, the turbidity appears to be driven by the pH and not the acid used to adjust the pH, as both lactic acid and citric acid produced similar results.

[0092] Additionally, a study was conducted to evaluate the effects of pH on foam diameter using citric acid and lactic acid. The foam diameter was measured as described in Example 1 above across a range of pHs, using a BERRY® Booster brand trigger. Prototype A was evaluated using both citric acid and lactic acid to adjust the pH. The results as shown in Figure 4. As shown, improved foam diameter was obtained when the Prototype A contained citric acid as opposed to lactic acid, and the broadest foam diameter was achieved with a pH ranging from 9-10.Attorney Docket No. 1116015-00-WO-01-HCExample 4

[0093] The degreasing performance of various competitor products were compared with the performance of Prototype A and Prototype B, as set forth in Example 1. The amount of surfactants for each of the comparison products and prototypes is listed below in Table 3. Surfactant percent determination for Products #1-4 was estimated by analytical testing.

[0094] Table 3 - Comparison Products

[0095] The ingredients listed for Product #1 include: water. CAP betaine, SLES, SLS. glycerin, glycol, fragrance, PEG-40, hydrogenated castor oil, MIT, CIT, and sodium hydroxide. The ingredients listed for Product #2 include: ethanol, citric acid, fragrance, lauramine oxide, laureth-7, MIT, CIT, PPG-2 butyl ether, PPG, sodium hydroxide, SLES, SLS chelant, and water. The ingredients listed for Product #3 include: Anionic Surfactants: <5%, Nonionic Surfactants <5%, Ethanol, CIT, MIT, Fragrance, Water. The ingredients listed for Product #4 include: Alcohol denat. Cl 0-10 Alkyldimethylamine Oxide, Dipropylene Glycol Butyl Ether, Ethanolamine, Fragrance, Hexyl Ethoxylate, Lauryl Glucoside, Phenoxyethanol, PPG-26, Sodium Citrate, Sodium Xylenesulfonate. Tetrasodium Glutamate Diacetate, Water.

[0096] The results demonstrated that Prototype A and Prototype B both began degreasing faster than any of Products #1-4. Product #1 and Product #2 (which contain the highest surfactant amount) presented similar foam adherence to Product #4 and both Prototypes A and B, while Product #3 had the lowest foam adherence. Product #2 had the lowest foam lasting. Product #3 presented the worst performance and also which correlated with the lowest surfactant percentage. Prototypes A and B had the largest foam diameter as compared to any of Products #1-4. It is noted that a large foam diameter may be desirable to consumers, as a broad foam diameter serves toAttorney Docket No. 1116015-00-WO-01-HCcover a larger area of the item being cleaned (e.g., dishes or utensils) and may result in fewer applications of the product to the item(s) being cleaned.Example 5

[0097] Two prototypes were prepared and tested for quantitative foam attributes such as volume, stability, and coverage. The prototypes (Prototype A and Prototype B) were prepared as set forth in Table 4 below.

[0098] Table 4 - Overview of Prototype A and Prototype B

[0099] To characterize the spray products, considering not only the formulations but also the impact of various trigger mechanisms in foam generation, the Kruss Dynamic Foam Analyzer (DFA) was used. In the testing method, the foam was directly sprayed into the DFA column, which allowed for the quantitative characterization of trigger-generated foam (without the presence of grease) along three points: foam stability, trigger efficiency, and foam structure. The different dish spray prototypes (A and B) as well as two control formulations were measured including their behavior across different triggers (e.g., AFA and Berry). The AFA trigger has a prolonged spraying system in which actuating the trigger once and holding it delivers foam for various seconds, i.e., fewer strokes are required, while the Berry trigger instead provides a pre-compressed spraying requiring continuous short strokes to deliver foam. Additionally, coverage tests were also conducted after spraying the formulations on different soiled surfaces in order to quantify each product’ s efficacy for this attribute.

[0100] DFA Analysis and Trigger-Generated Foam: The DFA method used a short prism column that provided an easier handling and required lower volumes versus other taller columns, allowing the direct atomization of a spray product. First, the spray product (packaging and formula) was weighed to determine its initial weight. Then, the product was atomized inside the column until it was filled completely. The column and holder were then placed in the DFA, and the foam was analyzed at the top section during 300 seconds, providing data for foam volume and structure.Attorney Docket No. 1116015-00-WO-01-HCFinally, the spray product was weighed once again to determine its final weight; then, the foam volume was calculated as created per unit mass (dosing efficacy).

[0101] Coverage Tests: The coverage testing quantified the amount of product consumed to achieve total coverage of a soiled surface. To begin, the selected surface was covered with the amount and soil of interest: 4 g of 14 olive oil, 14 butter, and 14 edible tallow with Sudan Red greasy soil. The surfaces selected were the same material and size in order to apply the soil over the same area and compare between samples. Once soiled, the surfaces were left to rest overnight. Next, the spray product of interest was weighed in order to record the initial weight. The spray product was then actuated several times until the soiled surface was completely covered in foam. The spray product was then once again weighed to record the final weight, and the consumed amount of product to achieve full coverage was calculated.

[0102] Results: Prototype A showed greater changes in foam stability depending on the trigger used, obtaining the best performance when combined with the Berry trigger. In the case of Prototype B, this showed similar results across the different triggers tested. Prototype A with the Berry trigger delivered a whitish foam with a slightly lower amount than others, but greater coverage. On the other hand, when tested with the AFA trigger, Prototype A delivered a significantly lower amount of foam, as observed in the DFA foam volume profiles. In the case of Prototype B, when combined with the AFA or Berry triggers, both cases visually showed similar foams, which was also observed in their similar DFA foam volume profiles. The results confirm that the performance behavior of a dish spray depends on both the dish spray formulation and the trigger mechanism. The Berry trigger showed overall the lowest dosing efficacy across the different formulas. The dosing efficacy can be related to the yielding of a product. This numerical finding could be also associated with sensorial observations, which overall identified a low yielding performance for the Berry trigger. Considering the formulas, Prototype A overall delivered more liquidish foams, which further associate with what was observed in the sensorial tests. Prototype B showed in general a foam with a higher air fraction.

[0103] With respect to the coverage tests, different surfaces were explored, including stainless steel pans, ceramic plates, and plastic plates. Each surface was explored twice for each Formula / trigger and an average was obtained. The results are shown in Table 5 below.

[0104] Table 5 - Comparison of grams consumed to fully cover a soiled surface across the different formulas and triggers.Attorney Docket No. 1116015-00-WO-01-HC

[0105] Data was obtained with the average of two measurements, i.e., each surface was measured twice for each formula / trigger. In all of the cases, the stainless steel area required higher amounts, as the pan’s surface was larger than the plastic / ceramic plate. Between triggers, the Berry trigger was less efficient regarding coverage / consumption. It is noted that while this experiment focused on quantifying consumption versus full coverage, foam aesthetics can also play a role in user experience.

[0106] The AFA trigger provided overall better dosing efficacy (foam volume created per unit mass) and coverage. Taking into account consumption, Prototype B presented a very good foam volume and stability performance with both triggers, while Prototype A did so only with the Berry trigger. The user experience of triggers themselves, i.e., how people usually actuate a trigger, may also be considered. In addition, it is mentioned that the method used herein focused on the analysis of foam and not degreasing, which is also an important attribute. Thus while this method helps us understand foaming capability / aesthetics, other attributes, such as degreasing, also play a role when being evaluated by users.
