Description

Technical Field

[0001] This invention relates to the field of foaming cleaning technology, specifically to facial cleansing mousse, foaming compositions, preparation methods, and uses. Background Technology

[0002] A cleansing mousse is a facial cleansing product that comes with a foaming pump. A cleansing mousse typically consists of a bottle and a pump. The pump is attached to the bottle, which contains a foaming liquid. When the pump is pressed, it simultaneously draws in the foaming liquid and air, which are then fully mixed in the pump's internal mixing chamber to form an air-liquid mixture. This mixture then passes through the pump's mesh to create foam. Users can then apply this foam to their hands, face, or other areas for cleansing.

[0003] The mesh density of pump heads is generally in the range of 100-400 mesh. Higher mesh counts result in finer foam. Using a high-density mesh of 300-400 mesh is a possible option for achieving finer foam. However, an overly dense mesh design significantly increases resistance during pressing, thus requiring a certain level of fluidity from the foaming liquid. If the foaming liquid viscosity is too high, the gas-liquid mixture will have difficulty passing smoothly through the dense mesh, easily leading to uneven foam size, poor elasticity, and short-lasting foam, and even clogging the mesh, severely impacting the user experience. One possible solution is to use a high-density mesh combined with a very low-viscosity, thin foaming liquid. This allows the gas-liquid mixture to pass smoothly through the fine pores and be evenly cut and fully encapsulated under pump pressure, making it easier to form fine, dense, and consistent foam. To obtain a foaming liquid with lower viscosity, a common practice is to greatly reduce the amount of surfactant (≤6%). However, this type of cleansing mousse has poor foam elasticity, foam durability, and foam uniformity. At the same time, the cleaning ability is also relatively weak due to the low surfactant content.

[0004] Therefore, how to provide a foaming liquid with a surfactant content of more than 6%, which can form foam with both greater durability and uniformity after passing through a 300-400 mesh screen to improve the performance, is a problem that needs to be solved. Summary of the Invention

[0020] In some technical solutions, the mass fraction of the polyol component is 10-15%.

[0021] In some technical solutions, the mass ratio of the lauroyl alanine tromethamine salt to the cocoyl glutamic acid TEA salt is 5:(2~4).

[0022] In some technical solutions, the mass fraction of the lauroyl alanine tromethamine salt is 6-10%.

[0023] In some technical solutions, the mass fraction of the cocoyl glutamic acid TEA salt is 4-8%.

[0024] In some technical solutions, the foaming composition further includes a second surfactant, which is used as an auxiliary surfactant. The second surfactant is selected from one or more of the following: sodium lauryl amphoteric acetate, potassium cocoyl glycinate, lauramide propyl betaine, cocoamide propyl betaine, lauryl betaine, sodium methyl cocoyl taurate, sodium cocoyl methyl taurate taurate, potassium lauryl phosphate, potassium lauryl polyether phosphate, sodium xylene sulfonate, sodium cocoyl glycinate, cocoyl hydroxy sulfobetaine, and lauryl hydroxy sulfobetaine.

[0031] In a third aspect, embodiments of this application provide a facial cleansing mousse, including...

[0032] A mousse bottle containing the foaming composition described in the first aspect or the foaming composition prepared according to the preparation method described in the second aspect;

[0033] Pump head, wherein the pump head has a 300-400 mesh opening;

[0034] The pump head is mounted on the mousse bottle and is used to press the foaming composition inside the mousse bottle to form foam.

[0035] In a fourth aspect, embodiments of this application provide the use of the foaming composition described in the first aspect or the foaming composition prepared according to the preparation method described in the second aspect in the preparation of foam.

[0036] In a fifth aspect, embodiments of this application provide the use of the foaming composition described in the first aspect or the foaming composition prepared according to the preparation method described in the second aspect in the preparation of a facial cleansing mousse.

[0037] The beneficial effects of the embodiments of the present invention include :

[0038] 1. The composition provided in this application embodiment produces a synergistic effect through a specific combination of a first surfactant with a content greater than 6% and a polyol component, resulting in foam with a large foam density, foam half-life and foam uniformity, thereby achieving a good balance of foam elasticity, foam durability and foam uniformity, and thus achieving excellent cleaning effect.

[0039] 2. In the composition of the embodiments of this application, the content of the first surfactant is greater than 6%, which has a strong cleaning ability.

[0040] 3. In the composition of the present application embodiment, the first surfactant is a combination of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt, which is more conducive to forming larger but relatively loose micelle morphology, rather than worm-like or hexagonal micelles that are prone to high viscosity. Therefore, the composition can have a high surfactant content but still maintain extremely low viscosity, which is conducive to the composition passing smoothly through the dense mesh of 300~400 mesh to form uniform and delicate foam.

[0041] 4. The fine, dense foam provides a gentler, more even cleansing experience. The small, dense foam particles act like a soft cushion on the face, reducing direct friction and irritation (especially beneficial for sensitive or dry skin, minimizing pulling sensations). Compared to larger, looser foam, the finer foam distributes more evenly into pores and facial folds, removing oil, dirt, and makeup residue more thoroughly yet gently, leaving skin feeling "clean but not irritated."

[0042] 5. The foam's strong elasticity and durability directly enhance the user experience. This elastic, "creamy" foam stays on the face longer and provides a noticeable bouncy feel during massage, making users feel the product is "high-end" and "effective," resulting in higher psychological satisfaction.

[0043] 6. In some embodiments, the facial cleansing mousse provided in this application includes a composition and a mousse bottle. The composition and the pump head of the mousse bottle are highly compatible, and the pumped foam can simultaneously meet the characteristics of fine foam, good foam elasticity, and high foam durability.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0050] Unless otherwise stated, the following terms are defined in the embodiments of this application.

[0051] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of those features.

[0052] The terms “comprising,” “containing,” “having,” and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0053] The term "foam half-life" refers to the time required for the volume of a foam to decay to half of its initial maximum volume.

[0054] The term "foam density" refers to the number of air bubbles per unit area, measured in units of (bubbles / mm²). 2 ).

[0055] The term "foam uniformity" refers to the degree of uniformity in the size of bubbles in the foam when the foaming composition forms foam. The smaller the size difference between bubbles, the higher the foam uniformity. Specifically, it can be judged by visually observing the foam structure formed after the foaming composition is processed by a foaming tool (such as a mousse bottle).

[0056] The term "foam fineness" refers to the fineness of the foam formed by the foaming composition. It can be characterized by a combination of foam density and foam uniformity. The higher the foam density value, the higher the foam uniformity, and the greater the foam fineness, the finer the foam. Fine foam usually has small and dense foam particles, a smooth texture like cream / mousse / silk, and no obvious large particles or bubbles. Overall, it presents a dense, delicate, uniform, and non-rough feel and visual experience.

[0057] The term "foam elasticity" refers to the elasticity of foam when a foaming composition forms foam. It can be characterized by a combination of foam density and foam half-life. The higher the foam density and the longer the foam half-life, the better the foam elasticity. Foam with good elasticity feels soft to the touch and has resilience, with a "bouncy" feel like a cloud or cotton candy, rather than being loose, thin, or collapsing at the slightest touch.

[0058] The term "foam durability" refers to how quickly a foam dissipates after being applied to the area to be cleaned, once the foaming composition has formed. It can be characterized by the foam half-life; the longer the foam half-life, the longer the foam durability. Foam with good durability can maintain its volume without significant collapse and dissipates slowly.

[0059] When a numerical range is involved, the numerical range includes the endpoint values ​​at both ends. For example, the numerical range A~B includes not only the values ​​within A~B, but also the values ​​at the endpoints A and B.

[0060] In addition to the above, it should be emphasized that the reference to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0061] <Composition>

[0062] In a first aspect, this application provides a composition comprising:

[0063] The first surfactant includes lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt;

[0064] Polyol components, including at least one polyol;

[0065] water;

[0066] Wherein, in the composition,

[0067] The mass fraction of the first surfactant is 9-20%.

[0068] The mass fraction of the polyol component is 5-30%.

[0069] The compositions of the embodiments of this application can achieve the following technical effects:

[0070] 1. The composition provided in this application embodiment can be used for foaming to form a foam liquid. When applied to the skin, the foam liquid can achieve a cleansing effect; it is understood that the foam liquid can be used to clean areas such as hands, face, and neck.

[0071] 2. The composition provided in this application embodiment produces a synergistic effect through a specific combination of the first surfactant and the polyol component, resulting in foam with greater foam density, foam half-life and foam uniformity, thereby achieving a good balance of foam elasticity, foam durability and foam uniformity, and thus achieving excellent cleaning effect.

[0072] 3. Foaming liquids containing high concentrations of surfactants (6% or more in the composition) are generally more viscous. The fundamental reason is that as the surfactant monomer concentration increases, the micelle morphology evolves from simple spherical shapes to more complex structures, such as layered, worm-like, or hexagonal micelles. While these large, entangled micelle morphologies are beneficial for dissolution at high concentrations, they significantly increase the system viscosity, making it difficult for the foaming liquid to pass smoothly through a 300-400 mesh high-density mesh. In the compositions of this application, the first surfactant is a combination of lauryl alanine tromethamine salt and cocoyl glutamic acid TEA salt, which is more conducive to forming larger but relatively loose micelle morphologies, rather than the worm-like or hexagonal micelles that easily lead to high viscosity. Therefore, the composition can have a high surfactant content while maintaining extremely low viscosity, which is beneficial for the composition to smoothly pass through a 300-400 mesh dense mesh to form a uniform and fine foam.

[0073] 4. In the composition of the embodiments of this application, the content of the first surfactant is greater than or equal to 9%, which has a strong cleaning ability.

[0074] 5. The fine, dense foam provides a gentler, more even cleansing experience. The small, dense foam particles act like a soft cushion on the face, reducing direct friction and irritation (especially beneficial for sensitive or dry skin, minimizing pulling sensations). Compared to larger, looser foam, the finer foam distributes more evenly into pores and facial folds, removing oil, dirt, and makeup residue more thoroughly yet gently, leaving skin feeling "clean but not harsh."

[0075] 6. The foam's strong elasticity and durability directly enhance the user experience. This elastic, "creamy" foam stays on the face longer and provides a noticeable bouncy feel during massage, making users feel the product is "high-end" and "effective," resulting in higher psychological satisfaction.

[0076] In some embodiments, the mass fraction of the first surfactant is 10-20%; this can improve cleaning ability.

[0077] In some embodiments, the mass ratio of lauroyl alanine tromethamine salt to cocoyl glutamic acid TEA salt is 10:(4~8), or 5:(2~4). This is beneficial for the foam formed by the composition to have a high foam density, foam half-life, and foam uniformity.

[0078] In some embodiments, the mass fraction of lauroyl alanine tromethamine salt is 6-10%. This is beneficial for the foam formed by the composition to have a high foam density, foam half-life, and foam uniformity.

[0079] In some embodiments, the mass fraction of cocoyl glutamic acid TEA salt is 4-8%. This is beneficial for the foam formed by the composition to have a high foam density, foam half-life, and foam uniformity.

[0080] In some embodiments, the mass fraction of the polyol component is 5-20%, optionally 8-20%, or optionally 10-15%.

[0081] In some embodiments, the mass ratio of the polyol component to the first surfactant is 1:(1~2).

[0082] In some embodiments, the polyol component includes a primary alcohol component selected from one or both of maltitol and sorbitol. The addition of sorbitol and maltitol can further improve the foam uniformity of the foam formed by the composition, that is, it is beneficial to form a finer foam.

[0083] In some embodiments, the mass ratio of the first alcohol component to the polyol component is (0.1~1):1. When the mass ratio of the added amount of sorbitol and / or maltitol to the total added amount of polyol is between (0.1~1):1, it is beneficial to further improve the foam uniformity of the foam formed by the composition and form a finer foam.

[0084] In some embodiments, the polyol component further includes a second alcohol component, which is selected from one or more of butylene glycol, propylene glycol, glycerin, dipropylene glycol, polyethylene glycol 400 (also known as PEG400), and PPG-7 (polypropylene glycol-7).

[0085] Optionally, propylene glycol is selected from one or more of 1,2-propanediol and 1,3-propanediol.

[0086] In some embodiments, the composition further includes a second surfactant, which serves as an auxiliary surfactant, and the second surfactant is selected from one or more of sodium lauryl amphoteric acetate, potassium cocoyl glycinate, lauramidopropyl betaine, cocoamide propyl betaine, lauryl betaine, sodium methyl cocoyl taurate, sodium cocoyl methyl taurate taurate, potassium lauryl phosphate, potassium laureth phosphate, sodium xylene sulfonate, sodium cocoyl glycinate, cocoyl hydroxy sulfobetaine, and lauryl hydroxy sulfobetaine.

[0087] In some embodiments, the mass fraction of the second surfactant is 3-5%.

[0088] In some embodiments, the composition further includes one or more of preservatives, fragrances, and humectants.

[0089] In some embodiments, the preservative includes one or more of sodium benzoate and phenoxyethanol. Optionally, the mass fraction of the preservative is 0.1-5%, optionally 0.5-2%, or optionally 0.5-1%.

[0090] In some embodiments, the water is deionized water.

[0176] <Experimental Example 1>

[0177] The compositions of Examples 1-17 and Comparative Examples 1-20 were used as samples, and the following experiments were conducted to detect the foam density, foam half-life, and foam uniformity of each sample.

[0178] 1. Experimental Methods

[0179] 1.1 Detection of foam density and foam half-life

[0180] The main method used is the FOAMSCAN™ foam analyzer. The main principle is to use stirring to generate foam in the sample. Based on the light transmittance of the sample, the density, height and structure of the foam are detected by the optical sensor of the foam analyzer.

[0181] The specific testing method is as follows:

[0182] Prepare the sample, transfer 100ml of sample (the sample is in solution form) into the foam analyzer, and stir the sample using an intermittent stirring foaming method to form foam; the preset foam volume at the stirring endpoint is 140ml, and the stirring speed is 1000rpm;

[0183] After stirring, a sample foam volume (ml) was taken every 10 seconds.

[0184] Stirring is stopped when the mixing reaches its endpoint. Upon stopping, an optical sensor photographs the foam, and a computer-based system counts the bubbles to obtain the number of bubbles per unit area, expressed as bubbles per mm. 2 ), to obtain the foam density;

[0185] After stirring is stopped, the foam analyzer continues to track the decay of foam volume over time. The foam volume at the moment stirring is stopped is taken as the initial volume. Then, a set of data is taken every 10 seconds until the foam volume (ml) is half of the initial volume. The time is recorded as the foam half-life, which is measured in seconds (S).

[0186] 1.2 Pump head discharge test;

[0187] Prepare the sample and pour it into a 150ml cleansing mousse bottle. The cleansing mousse bottle is equipped with a high-density mesh mousse pump head with a mesh size of 400. Press the pump to dispense the sample and visually observe the shape of the dispensed foam, paying attention to the uniformity of the foam. A score of 0 is given for poor uniformity. Figure 2 As shown, a score of 10 is given for very good uniformity, such as... Figure 3 As shown.

[0188] 2. Experimental Results and Analysis

[0189] The experimental results are shown in Figures 1-5 See Tables 5 and 6.

[0190] Figure 1 This is a photograph obtained by taking a picture of the foam of the sample in Example 1 using an optical sensor;

[0191] Figure 2 The graph shows the test results of foam uniformity in Example 1, with a foam uniformity score of 8.

[0192] Figure 3 The graph shows the test results for foam uniformity in Comparative Example 3, where the foam uniformity score is 0.

[0193] Figure 4 The graph shows the test results for foam uniformity in Comparative Example 7, with a foam uniformity score of 5.

[0194] Figure 5The graph shows the test results of foam uniformity in Example 6, with a foam uniformity score of 10.

[0195] The foam density, foam half-life, and foam uniformity results for samples of Comparative Examples 1-20 are shown in Table 5. The foam density, foam half-life, and foam uniformity results for samples of Examples 1-17 are shown in Table 6.

[0196] Table 5

[0197] Table 6

[0198] (1) Comparison of Example 1 and Comparative Examples 1-2

[0199] The difference between Example 1 and Comparative Examples 1-2 is that the first surfactant in the composition of Example 1 is a combination of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt, while the surfactant in the compositions of Comparative Examples 1-2 is only one of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt.

[0200] As shown in Table 6 and Figures 1-2 As shown, the foam formed by the composition provided in Example 1 after being sprayed from a high-density mesh mousse pump head has a high foam density per unit area (e.g., Figure 1 As shown), the foam uniformity is high (e.g. Figure 2 As shown, the foam half-life of the composition in Comparative Example 1 is relatively long; in contrast, the foam formed by the composition in Comparative Example 1 has a higher foam density per unit area, lower foam uniformity, and a shorter foam half-life; the foam formed by the composition in Comparative Example 2 has a lower foam density per unit area, higher foam uniformity, and a shorter foam half-life.

[0201] Therefore, the surfactant combination containing lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt can produce a synergistic effect, enabling the composition to achieve high foam density, foam uniformity and long foam half-life after foaming, thus making it more conducive to obtaining fine, elastic and long-lasting foam.

[0202] (2) Comparison of Example 1 and Comparative Examples 3-15

[0203] The difference between Example 1 and Comparative Examples 3-15 is that lauroyl alanine tromethamine salt was replaced with other components.

[0204] As shown in Tables 5-6, the foam uniformity of the compositions in Comparative Examples 3-15 was lower than that in Example 1. This indicates that at higher levels of the first surfactant, the combination of cocoyl glutamic acid TEA salt and lauroyl alanine tromethamine salt, compared to combinations of cocoyl glutamic acid TEA salt and other components, significantly improves the foam uniformity of the composition and results in higher foam density and a longer foam half-life. In other words, the surfactant combination of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt is beneficial for obtaining fine, elastic, and durable foam.

[0205] (3) Comparison of Example 1 and Comparative Example 16

[0206] The difference between Example 1 and Comparative Example 16 is that TEA salt of cocoyl glutamate was replaced with sodium cocoyl glutamate.

[0207] Compared to Example 1, the foams formed by the compositions of Comparative Examples 3-15 had lower foam uniformity and density, and shorter foam half-life. Therefore, the combination of TEA cocoyl glutamate and lauroyl alanine tromethamine salt, compared to the combination of sodium cocoyl glutamate and lauroyl alanine tromethamine salt, can improve foam uniformity and density, and prolong foam half-life.

[0208] (4) Comparison of Example 4 and Comparative Example 17

[0209] The difference between Comparative Example 17 and Example 4 is that Comparative Example 17 has a higher amount of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt added, and the total amount of surfactant added is 23%.

[0210] As shown in Table 2, the composition of Comparative Example 17 produced foam with lower uniformity, while the composition of Example 4 produced foam with higher uniformity. The comparison shows that adding less than or equal to 20% of the surfactant combination of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt is beneficial for improving foam uniformity.

[0211] (5) Comparison of Examples 1-5 and Comparative Examples 18-19

[0212] The main difference between Examples 1-5 and Comparative Example 18 is that the amount of lauroyl alanine tromethamine salt and cocoyl glutamic acid TEA salt added is different, and the ratio of these two components is larger (greater than 2.5).

[0213] As shown in Table 2, the compositions of Comparative Examples 18 and 19 produced foam with lower uniformity, and Comparative Example 19 also had lower foam density and foam half-life. In contrast, the compositions provided in Examples 1-5 had a mass ratio of lauroyl alanine tromethamine salt to cocoyl glutamic acid TEA salt in the range of 10:4 to 8, resulting in high foam uniformity, higher foam density per unit area, and longer foam half-life, which is more conducive to the formation of fine, elastic, and durable foam.

[0214] (5) Comparison of Examples 6-17 and Comparative Example 20

[0215] The main difference between Examples 6-17 and Comparative Example 20 is that the alcohol components are different; Comparative Example 20 uses ethanol instead of polyols.

[0216] Compared to Examples 6-17, the composition of Comparative Example 20 resulted in foam with lower density per unit area, shorter half-life, and lower uniformity. This indicates that the addition of polyols can increase foam density per unit area, prolong foam half-life, and improve foam uniformity, thus contributing to the formation of fine, elastic, and durable foam.

[0217] (6) Effects of sorbitol and / or maltitol on foam

[0218] Compared to Examples 1-5 and 8-11, the polyols in Examples 6-7 and 12-17 were wholly or partially incorporating sorbitol and / or maltitol.

[0219] The experimental results show that the foam uniformity of the compositions containing sorbitol and / or maltitol (Examples 6-7 and 12-17) is generally above 8 points, which is higher than that of the compositions lacking sorbitol and / or maltitol (Examples 1-5 and 8-11). Therefore, the addition of sorbitol and maltitol can further improve the foam uniformity of the foam formed by the composition, that is, it is beneficial to form finer foam.

[0220] (7) Effect of the mass ratio of sorbitol and / or maltitol to polyols on foam.

[0221] In the compositions provided in Examples 6-7 and Examples 12-17, the mass ratio of the amount of sorbitol and / or maltitol added to the total amount of polyols added is (0.1-1):1.

[0222] Therefore, it can be seen that when the mass ratio of the amount of sorbitol and / or maltitol added to the total amount of polyol added is between (0.1~1):1, it is beneficial to further improve the foam uniformity of the foam formed by the composition and form a finer foam.

[0223] (8) The effect of alcohol type on foam

[0224] Comparative Examples 6-17 and Comparative Example 20 differ only in that Comparative Example 20 did not use polyols, but used ethanol.

[0225] The foam formed by the composition in Comparative Example 20 had low foam density, short foam half-life, and low foam uniformity; while the foam formed by the compositions in Examples 6-17 had high foam uniformity, high foam density, and long foam half-life. This indicates that the addition of polyols to the composition can increase the foam density per unit area, prolong the foam half-life, and improve foam uniformity, thus contributing to the formation of fine, elastic, and durable foam.
