Description

Technical Field

[0001] This application belongs to the field of cosmetic technology, specifically relating to a triple film-forming water essence lipstick and its preparation method. Background Technology

[0002] Lipsticks can generally be divided into glossy lipsticks and matte lipsticks according to their shine. Although existing glossy lipsticks can produce a glossy effect, the colorants and oil components in glossy lipsticks are miscible. When the lips with glossy lipsticks come into contact with smooth objects (such as glass cups, the back of the hand, etc.), the colorants in the lipsticks are easily left on the surface of the smooth objects along with the oil components, resulting in phenomena such as smudging and color fading.

[0003] In addition, traditional lipstick formulations only contain oil and wax components, which are incompatible with water. Therefore, traditional lipstick formulations are usually ahydrous or contain very little water, resulting in an oily and suffocating feeling and a lack of moisture. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a triple-film-forming water essence lipstick and its preparation method. When applied to the lips, this triple-film-forming water essence lipstick forms a specific three-layer film structure, thereby providing the lips with not only a moisturizing feel, hydration, and skincare benefits, but also reducing lipstick transfer and fading.

[0005] The first aspect of this application provides a triple film-forming water essence lipstick, comprising, by weight:

[0006] Phenyl silicone oil: 30-45 parts, including at least one of diphenyl polydimethylsiloxane, trimethylpentaphenyltrisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxaneoxyphenyl polydimethylsiloxane;

[0007] Film-forming oil phase: 15-35 parts, including oil phase film-forming agent and oil phase film-forming aid; wherein, the oil phase film-forming aid includes phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimer linoleate, and the mass percentage of phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimer linoleate in the lipstick is 1%-10%;

[0008] Film-forming aqueous phase: 5-20 parts, including aqueous film-forming agent;

[0009] Emulsifier: 0.5 to 5 parts, including at least one of lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane and lauryl PEG-9 polydimethylsiloxane;

[0010] Dispersant: 1 to 5 parts, including polyglycerol-2 triisostearate;

[0011] Thickener: 0.1 to 0.5 parts, including silachlorite hydrate.

[0012] Not intended to be limited by any theory or explanation, the inventors pioneered a combination of three components—phenyl silicone oil, a film-forming oil phase, and a film-forming aqueous phase—into the lipstick formula to address the issues of glossy lipsticks easily transferring to cups and lacking moisture. The film-forming oil phase and film-forming aqueous phase each contain an oil-phase film-forming agent and an aqueous-phase film-forming agent, respectively, which form an oil phase film and an aqueous phase film after the triple-film-forming water essence lipstick is applied to the lips. Thus, the triple-film-forming water essence lipstick forms a triple film-forming system on the lip skin surface: an aqueous phase film, an oil phase film, and a phenyl silicone oil layer. The aqueous phase film, due to its hydrophilicity, has affinity with the lip skin and forms on the lip skin surface; the phenyl silicone oil layer has the lowest polarity and easily migrates to surfaces exposed to air; the oil phase film, with intermediate polarity, forms between the aqueous phase film and the phenyl silicone oil layer. The aqueous phase film layer, upon contact with the lip skin, provides a hydrating sensation. Furthermore, other components in the aqueous phase film layer, such as additives and active ingredients, further enhance the hydration and provide moisturizing and skincare benefits. Under the action of the oil phase film-forming agent and oil phase film-forming aid, other oil phase components, including pigments, work together to form the oil phase film layer, providing the coloring effect. Protected by the outermost phenyl silicone oil layer, when the lips applying the triple-film-forming water essence lipstick come into contact with a smooth object, only a surface phenyl silicone oil film remains on the object's surface; the colorants in the middle layer do not adhere to the object's surface with the oil film. This reduces lipstick transfer and fading. In the triple-film-forming system, the oil phase film-forming aid located in the middle layer is phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimerlinoleate. Its unique water-holding and viscosity-controlling properties promote the phase separation process between the three film layers, ensuring both non-transfer and moisturizing effects.

[0013] Furthermore, during the research and development process, the inventors discovered that it was difficult to compound phenyl silicone oil, the film-forming oil phase, and the film-forming water phase. Due to the incompatibility of water and oil, demulsification and the formation of "residue" were prone to occur during the preparation of the triple film-forming water essence lipstick, making it impossible to form a stable emulsion system. After further curing, it was impossible to obtain a stick-shaped lipstick with a defect-free surface (the surface had color bands or unevenness). Faced with this predicament, the inventors unexpectedly discovered through persistent attempts that the combined use of the specific emulsifier, dispersant, and thickener mentioned in this application could promote the stability of the triple film-forming water essence lipstick emulsion system, thereby producing a triple film-forming water essence lipstick with a high yield rate.

[0014] The triple film-forming water essence lipstick of this application not only provides the lips with moisture, hydration and skin care effects through the triple film-forming system, reducing lipstick transfer and fading, but also ensures quality stability in the production process through formula design, thereby achieving a high yield and facilitating the mass production of the triple film-forming water essence lipstick.

[0015] In any embodiment of this application, the mass percentage of phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimer linoleate in the lipstick is 3% to 7%.

[0016] In any embodiment of this application, the aqueous phase for film formation is 10 to 20 parts.

[0018] In any embodiment of this application, the mass ratio of the oil phase film-forming aid to the oil phase film-forming agent is (0.1 to 0.5):1.

[0019] In any embodiment of this application, the film-forming oil phase further includes grease, pigment, and wax.

[0020] In any embodiment of this application, the aqueous film-forming agent includes at least one of polyurethane-1 and acrylate copolymers.

[0021] In any embodiment of this application, the aqueous phase for film formation further includes deionized water, polyols, and active ingredients.

[0022] In any embodiment of this application, the active ingredient is selected from one or a mixture of several of the following: Myrothamnus flabellifolia leaf / stem extract, acetylated sodium hyaluronate, sodium hyaluronate, sodium hyaluronate crosspolymer, hydrolyzed sodium hyaluronate, Paeonia suffruticosa seed oil, Paeonia suffruticosa root extract, squalane, Aloe barbadensis leaf juice, and collagen.

[0023] The second aspect of this application provides a method for preparing a triple-film-forming water essence lipstick, comprising the following steps:

[0024] The preparation of phase A includes mixing phenyl silicone oil, film-forming oil phase, emulsifier, dispersant, and thickener, heating to 80-90℃, and stirring until homogeneous to obtain phase A;

[0025] The preparation of phase B includes stirring at least a portion of the components of the film-forming aqueous phase until homogeneous, heating to 80-90°C, to obtain phase B, wherein at least a portion of the components includes an aqueous film-forming agent but does not include active substances.

[0026] The preparation of the mixture includes mixing phase B and phase A evenly to obtain the mixture;

[0027] The preparation of a triple film-forming water essence lipstick includes cooling a mixture to obtain a triple film-forming water essence lipstick.

[0028] In any embodiment of this application, the preparation of the mixture includes: mixing phase B and phase A evenly, cooling to 75-80°C, adding active material and stirring evenly to obtain the mixture. Detailed Implementation

[0029] To make the purpose, technical solution, and beneficial technical effects of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0030] For simplicity, this application only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form a range not explicitly stated; and any lower limit can be combined with other lower limits to form a range not explicitly stated, just as any upper limit can be combined with any other upper limit to form a range not explicitly stated. Furthermore, although not explicitly stated, every point or individual value between the endpoints of the range is included within that range. Therefore, each point or individual value can be used as its own lower or upper limit and combined with any other point or individual value or with other lower or upper limits to form a range not explicitly stated.

[0031] In the description of this application, it should be noted that, unless otherwise stated, "above" and "below" include the stated number, and "multiple" in "one or more" means two or more.

[0032] The foregoing description of this application is not intended to describe every disclosed implementation or method. Instead, the following description provides more specific examples of exemplary embodiments. Throughout the application, guidance is provided through a series of embodiments that can be used in various combinations. The examples listed are representative only and should not be construed as exhaustive.

[0033] As described in the background section, the colorants in glossy lipsticks are miscible with the oil components. When lips coated with glossy lipstick come into contact with a smooth object (such as a glass or the back of a hand), the colorants in the lipstick easily remain on the surface of the smooth object along with the oil components, resulting in phenomena such as transfer and color fading. In addition, traditional lipstick formulations only contain oil and wax components, which are incompatible with water. Therefore, traditional lipstick formulations are usually ahydrous or contain very little water, leading to a greasy feeling and a lack of moisture.

[0034] In view of this, the inventor, through in-depth research and extensive experiments, has provided a triple film-forming water essence lipstick and its preparation method.

[0035] The first aspect of this application provides a triple film-forming water essence lipstick, which, by weight, comprises 30-45 parts of phenyl silicone oil, 15-35 parts of film-forming oil phase, 5-20 parts of film-forming water phase, 0.5-5 parts of emulsifier, 1-5 parts of dispersant, and 0.1-0.5 parts of thickener.

[0036] In the triple film-forming water essence lipstick of this application, the phenyl silicone oil includes at least one of diphenyl polydimethylsiloxane, trimethylpentaphenyltrisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxaneoxyphenyl polydimethylsiloxane.

[0037] The film-forming oil phase includes an oil-phase film-forming agent and an oil-phase film-forming aid. The oil-phase film-forming aid includes phytosterol / isostearyl / cetearyl / stearyl / behenol dimerlinoleate, and the mass percentage of phytosterol / isostearyl / cetearyl / stearyl / behenol dimerlinoleate in the lipstick is 1% to 10%, for example, it can be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or within any two of the above values. The aforementioned oil-phase film-forming agent can include any oil-phase film-forming agent known in the art that can be used in lip makeup products. It is understood that the film-forming oil phase may also include other oil-phase components. Other oil-phase components may include, but are not limited to, oil-phase components of lip makeup products known in the art, such as oils, pigments, waxes, and other oil-phase additives.

[0038] The film-forming aqueous phase includes an aqueous film-forming agent. It is understood that the film-forming aqueous phase may also include other aqueous components. The aforementioned aqueous film-forming agent may include any aqueous film-forming agent known in the art that can be used in lip makeup products. It is understood that other aqueous components may include, but are not limited to, aqueous components known in the art that can be used in lip makeup products, such as deionized water, polyols, active ingredients, and other aqueous additives.

[0039] The emulsifier includes at least one of lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane and lauryl PEG-9 polydimethylsiloxane.

[0040] The dispersant includes polyglycerol-2 triisostearate.

[0041] Thickeners include silachlorite hydrate.

[0042] Not intended to be limited by any theory or explanation, the inventors pioneered a combination of three components—phenyl silicone oil, a film-forming oil phase, and a film-forming aqueous phase—into the lipstick formula to address the issues of glossy lipsticks easily transferring to cups and lacking moisture. The film-forming oil phase and film-forming aqueous phase each contain an oil-phase film-forming agent and an aqueous-phase film-forming agent, respectively, which form an oil phase film and an aqueous phase film after the triple-film-forming water essence lipstick is applied to the lips. Thus, the triple-film-forming water essence lipstick forms a triple film-forming system on the lip skin surface: an aqueous phase film, an oil phase film, and a phenyl silicone oil layer. The aqueous phase film, due to its hydrophilicity, has affinity with the lip skin and forms on the lip skin surface; the phenyl silicone oil layer has the lowest polarity and easily migrates to surfaces exposed to air; the oil phase film, with intermediate polarity, forms between the aqueous phase film and the phenyl silicone oil layer. The aqueous phase film layer, upon contact with the lip skin, provides a hydrating sensation. Furthermore, other components in the aqueous phase film layer, such as additives and active ingredients, further enhance the hydration and provide moisturizing and skincare benefits. Under the action of the oil phase film-forming agent and oil phase film-forming aid, other oil phase components, including pigments, work together to form the oil phase film layer, providing the coloring effect. Protected by the outermost phenyl silicone oil layer, when the lips applying the triple-film-forming water essence lipstick come into contact with a smooth object, only a surface phenyl silicone oil film remains on the object's surface; the colorants in the middle layer do not adhere to the object's surface with the oil film. This reduces lipstick transfer and fading. In the triple-film-forming system, the oil phase film-forming aid located in the middle layer is phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimerlinoleate. Its unique water-holding and viscosity-controlling properties promote the phase separation process between the three film layers, ensuring both non-transfer and moisturizing effects.

[0043] Furthermore, during the research and development process, the inventors discovered that it was difficult to compound phenyl silicone oil, the film-forming oil phase, and the film-forming water phase. Due to the incompatibility of water and oil, demulsification and the formation of "residue" were prone to occur during the preparation of the triple film-forming water essence lipstick, making it impossible to form a stable emulsion system. After further curing, it was impossible to obtain a stick-shaped lipstick with a defect-free surface (the surface had color bands or unevenness). Faced with this predicament, the inventors unexpectedly discovered through persistent attempts that the combined use of the specific emulsifier, dispersant, and thickener mentioned in this application could promote the stability of the triple film-forming water essence lipstick emulsion system, thereby producing a triple film-forming water essence lipstick with a high yield rate.

[0044] The triple film-forming water essence lipstick of this application not only provides the lips with moisture, hydration and skin care effects through the triple film-forming system, reducing lipstick transfer and fading, but also ensures quality stability in the production process through formula design, thereby achieving a high yield and facilitating the mass production of the triple film-forming water essence lipstick.

[0045] In some embodiments, the mass percentage of phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimer linoleate in the lipstick can be 3% to 7%. For example, the mass percentage of phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimer linoleate in the lipstick can be 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, or within any two of the above values.

[0046] It is not intended to be limited by any theory or explanation. When the mass percentage of phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimerlinoleate in the triple film-forming water essence lipstick is within the above-mentioned appropriate range, on the one hand, it can make the triple film-forming water essence lipstick present a better glossy effect after makeup application, making the lips appear more three-dimensional and full. On the other hand, it can increase the upper limit of the water phase content in the triple film-forming water essence lipstick, so that the water phase content in the triple film-forming water essence lipstick system can stably reach 15-20 parts, thereby further improving the water-based feel and moisturizing effect of the triple film-forming water essence lipstick.

[0047] In some embodiments, the aqueous phase for film formation can be 10 to 20 parts. For example, the content of the aqueous phase for film formation can be 10 parts, 12 parts, 15 parts, 18 parts, 20 parts, or within the range of any two of the above values.

[0048] In the above embodiments, the amount or ratio of each material in the triple film-forming water essence lipstick formula can be adjusted so that the water phase content in the triple film-forming water essence lipstick system can be stably reached 10 to 20 parts. For example, the upper limit of the water phase content in the triple film-forming water essence lipstick can be increased by adjusting the mass percentage of phytosterol / isostearyl / cetearyl alcohol / stearyl / behenol dimer linoleate in the triple film-forming water essence lipstick.

[0049] According to the above implementation method, the film-forming water phase in the triple film-forming water essence lipstick has a high addition amount, which is beneficial to improve the wateriness and moisturizing effect of the triple film-forming water essence lipstick.

[0050] In some embodiments, the oil phase film-forming agent may include at least one of VP / hexadecene copolymer, VP / eicosene copolymer, phenylpropyl dimethylsiloxane silicate, and acrylate / polytrimethylsiloxane methacrylate copolymer.

[0051] In some embodiments, the mass ratio of the oil phase film-forming aid to the oil phase film-forming agent can be (0.1 to 0.5):1, for example, it can be 0.1:1, 0.2:1, 0.3:1, 0.4:1, 0.5:1, or within any two of the above ratios.

[0052] In some embodiments, the film-forming oil phase may further include grease, pigments, and waxes.

[0053] This application does not impose specific restrictions on the types of conventional components applicable to lip makeup products, such as oils, pigments, and waxes. Those skilled in the art can select appropriate types of oils, pigments, and waxes according to actual needs.

[0054] For example, the oil may be selected from at least one of the following: methyl rosinate, octyl dodecyl neopentyl ester, isohexadecane, isododecyl, polyglycerol-2 triisostearate, diisostearate malate, bis-diglycerol polyacryl adipate-1, polyisobutylene, di-linoleyl alcohol di-linoleate, polyglycerol-2 isostearate / di-linoleate copolymer, phytosterol / octyl dodecyl lauroyl glutamate.

[0055] For example, the pigment may be selected from at least one of CI 15850, CI 77491, CI 77492, CI 77499, CI 77891, CI42090, CI 19140CI, 15985, CI 45410, CI 45380, and CI 16035.

[0056] For example, the wax may be selected from at least one of synthetic wax, polyethylene wax, microcrystalline wax, ceresin wax, carnauba wax, candelilla wax, paraffin wax, ethylene / propylene copolymer, and beeswax.

[0057] In some embodiments, the aqueous film-forming agent may include at least one of polyurethane-1 and acrylate copolymers.

[0058] In some embodiments, the aqueous phase for film formation may further include deionized water, polyols, and active ingredients.

[0059] In some embodiments, the active ingredient may be selected from one or a mixture of several of the following: Myrothamnus flabellifolia leaf / stem extract, acetylated sodium hyaluronate, sodium hyaluronate, sodium hyaluronate crosspolymer, hydrolyzed sodium hyaluronate, Paeonia suffruticosa seed oil, Paeonia suffruticosa root extract, squalane, Aloe barbadensis leaf juice, and collagen.

[0060] The second aspect of this application provides a method for preparing a triple film-forming water essence lipstick, comprising the following steps S10 to S40.

[0061] S10, Preparation of Phase A, includes mixing phenyl silicone oil, film-forming oil phase, emulsifier, dispersant and thickener, heating to 80-90℃, and stirring evenly to obtain Phase A.

[0062] In step S10, stirring until homogeneous indicates that the components in phase A are basically dissolved and evenly dispersed, resulting in a uniform dispersion system.

[0063] S20, preparing phase B, comprising stirring at least a portion of the components of the film-forming aqueous phase evenly, heating to 80-90°C to obtain phase B, wherein at least a portion of the components includes the aqueous film-forming agent and does not include active substances.

[0064] In step S20, at least a portion of the components of the film-forming aqueous phase may include components that can withstand temperatures of 80–90°C, such as components other than the active ingredient. It is understood that when all components of the film-forming aqueous phase can withstand temperatures of 80–90°C, step S20 may include uniformly stirring all components of the film-forming aqueous phase and heating it to 80–90°C to obtain phase B. In one example, the temperature of phase B may be the same as that of phase A, thus eliminating the temperature difference between phase A and phase B, which is beneficial for the uniform mixing of phases A and B.

[0065] S30, preparing a mixture, including mixing phase B and phase A evenly to obtain a mixture.

[0066] In step S30, phase B and phase A can be mixed evenly by homogenizing and stirring. For example, phase B can be slowly added to phase A and homogenized and stirred at 4000-7000 rpm for 10-20 minutes to make phase B and phase A evenly mixed.

[0067] S40, preparing a triple film-forming water essence lipstick, including cooling the mixture to obtain a triple film-forming water essence lipstick.

[0068] In the preparation method of this application, the phenyl silicone oil, film-forming oil phase, emulsifier, dispersant, thickener and film-forming aqueous phase can be selected from the phenyl silicone oil, film-forming oil phase, emulsifier, dispersant, thickener and film-forming aqueous phase of the first aspect. The embodiments of phenyl silicone oil, film-forming oil phase, emulsifier, dispersant, thickener and film-forming aqueous phase have been described above, and will not be repeated here.

[0069] According to the preparation method of this application, through specific formulation design, the risk of emulsification can be reduced during the preparation of the triple film-forming water essence lipstick, forming a stable emulsion system, thereby obtaining a stick-shaped triple film-forming water essence lipstick with a defect-free surface. The preparation method of this application is simple and easy to implement. The prepared triple film-forming water essence lipstick not only provides the lips with a sense of moisture, hydration, and skin care effects through the triple film-forming system, reducing phenomena such as lipstick transfer and fading, but also has high quality stability and yield.

[0070] In some embodiments, the preparation of the mixture may specifically include: mixing phase B and phase A evenly, cooling to 75-80°C, adding active ingredients and stirring evenly to obtain the mixture.

[0124] Test section

[0125] (1) Tack test

[0126] a. Tack test on smooth skin surface

[0127] The lipstick was applied to the subject's lips, and a stopwatch was started immediately. After 5 minutes, the lips with lipstick were gently touched to the skin of the arm, and the traces on the skin were observed to assess the degree of lipstick transfer.

[0128] b. Glass surface sticking test

[0129] Apply the lipstick to the subject's lips and immediately start the stopwatch. After 5 minutes, use a clean, transparent glass to gently press the lips with the glass and then observe the marks on the glass to assess the degree of lipstick transfer.

[0130] (2) Yield testing

[0131] Following the formulations and steps of the above-described embodiments and comparative examples, 20 lipsticks were prepared for each embodiment and comparative example. During the preparation process, the emulsion system was observed for phenomena such as emulsification, layering, oiliness, or unevenness. After preparation, the morphology of the lipsticks was observed. If the lipstick was a uniform, smooth, and flat solid, it was considered a qualified product; otherwise, it was considered a defective product. Yield = Number of qualified products / 20 × 100%.

[0132] (3) Moisturizing and transdermal water loss test

[0133] Ten participants with similar skin types and age ranges were selected to minimize the impact of individual differences on the test results. Three different sites were selected on each volunteer's lips for testing. Using a Corneometer CM825 (Courage-Khazaka, Germany) CU probe, the initial skin moisture content was measured and recorded at each selected site. After measuring the initial moisture content, the participants applied a thin layer of lipstick sample evenly to their lips. The amount and evenness of application were controlled to ensure consistency of the test. At different time points after lipstick application (immediately and 4 hours), the moisture content was measured and recorded again at each site using the moisture content probe, and the average value was taken as the skin moisture content at the corresponding time point. Based on the measured data, the rate of change of skin moisture at each site at different time points was calculated. The rate of change of moisture content can be calculated using the following formula: Rate of change of moisture content = (Moisture content after lipstick application - Initial moisture content) / Initial moisture content × 100%.

[0134] The average rate of moisture change of the lip skin of each subject at each time point was calculated as the moisture change rate of the lipstick at each time point. Among them, the immediate moisture change rate was recorded as Q1, and the 4-hour moisture change rate was recorded as Q2.

[0135] The test results of each embodiment and comparative example are shown in Table 2.

[0140] In Table 2, "non-stick" indicates that no sticking occurred in either the sticking test on smooth skin or the sticking test on glass. "Sticking" indicates that sticking occurred in both the smooth skin and glass tests. In Table 2, " / " indicates that the corresponding test was not performed. For example, the lipsticks in Comparative Examples 4-9 all had substandard materials during the manufacturing process, making it impossible to produce finished lipsticks; therefore, sticking, moisturizing, and transdermal water loss tests were not performed.

[0141] As can be seen from Tables 1 and 2, the triple film-forming water essence lipstick of this application introduces phenyl silicone oil, a film-forming oil phase, and a film-forming water phase into the lipstick formula, resulting in a triple film-forming system on the surface of the lips consisting of a water phase film layer, an oil phase film layer, and a phenyl silicone oil layer. Therefore, the prepared triple film-forming water essence lipstick is not only less prone to transfer but also has an excellent water-gloss effect, effectively increasing the hydration and moisturization of the lips, making them fuller. Specifically, in the triple film-forming water essence lipstick formulas of Examples 1-21, the mass percentage of phytosterol / isostearyl / cetearyl / stearyl / behenol dimerlinoleate in the lipstick is within a suitable range, which can increase the upper limit of the water phase content in the triple film-forming water essence lipstick. Therefore, compared to Examples 22-23, the triple film-forming water essence lipsticks of Examples 1-21 have better hydrating and moisturizing effects. Furthermore, the triple film-forming water essence lipstick of this application, through the combined use of specific emulsifiers, dispersants, and thickeners, can effectively reduce the risk of emulsion system separation, aggregation, or demulsification, thereby giving the triple film-forming water essence lipstick a better texture and appearance. Therefore, the yield rate of the triple film-forming water essence lipsticks in Examples 1-23 can all reach 100%.

[0142] In contrast, the lipstick formula of Comparative Example 1 did not contain the oil-phase film-forming aids phytosterol / isostearyl / cetyl alcohol / stearyl / behenol dimerlinoleate, while the lipstick formulas of Comparative Examples 2 and 3 used other oil-phase film-forming aids. Therefore, when the lipsticks of Comparative Examples 1-3 were applied to the lips, they could not achieve the triple film-forming effect of the aqueous phase film layer-oil film layer-phenyl silicone oil layer similar to the triple film-forming water essence lipstick of this application. Consequently, the lipsticks of Comparative Examples 1-3 still exhibited transfer when applied to the lips. Furthermore, although the aqueous phase content of the lipstick formulas of Comparative Examples 1-3 was similar to that of Examples 1-15, the hydrating and moisturizing effects of the lipsticks of Comparative Examples 1-3 were significantly inferior to those of Examples 1-15. This further demonstrates that in the triple film-forming system, the aqueous phase film layer, which is in direct contact with the lips, can effectively improve the hydration and moisturizing properties of the lips.

[0143] Comparative Example 4, which did not contain emulsifiers, experienced significant demulsification during preparation, resulting in stratification of the lipstick and an inability to obtain a uniformly mixed lipstick. Comparative Examples 5 and 6, although containing emulsifiers, showed limited stabilizing effects compared to lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane, failing to achieve synergistic effects with other materials. This resulted in oiliness in the prepared lipstick and an inability to obtain a uniformly mixed lipstick.

[0144] The lipstick formula in Comparative Example 7 did not contain a dispersant. During the preparation process, it was difficult to mix the materials evenly, resulting in an unmixed lipstick consistency. Although the lipstick formula in Comparative Example 8 contained a dispersant, compared to polyglycerol-2 triisostearate, other dispersants had a poorer dispersing effect on the materials and could not produce a synergistic effect when combined with other materials. During the preparation process, it was still difficult to mix the materials evenly, and an unmixed lipstick consistency could not be obtained.

[0145] Although the lipstick formula of Comparative Example 9 contained a thickener, compared with silachlor hydrosmite, other thickeners could not be combined with other materials to produce a synergistic effect, resulting in the lipstick material collapsing after cooling and failing to produce a shaped lipstick.

[0146] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
