Description

Technical Field

[0001] The present application belongs to the technical field of cosmetics, and specifically relates to a triple film-forming water essence lipstick and a preparation method thereof. Background Art

[0002] Lipsticks can be generally divided into glossy lipsticks and matte lipsticks according to their glossiness. Although existing glossy lipsticks can present a glossy effect, the colorant in the glossy lipstick is soluble in oil components. When the lips with glossy lipstick come into contact with smooth objects (such as glasses, backs of hands, etc.), the colorant in the lipstick is likely to remain on the surface of the smooth object together with the oil components, resulting in cup staining, color fading, etc.

[0003] In addition, the traditional lipstick formula system only contains oil and wax components, which are incompatible with water. Therefore, the traditional lipstick formula system is usually free of water phase or contains a very small amount of water phase, resulting in a greasy feeling and lack of moisture. Summary of the invention

[0004] To solve the above problems, the present application provides a triple film-forming water essence lipstick and a preparation method thereof. After the triple film-forming water essence lipstick is applied to the lips, it can form a specific three-layer film structure, which can not only provide hydration, moisturizing and skin care effects to the lips, but also reduce the phenomenon of lipstick sticking to the cup and fading.

[0005] The first aspect of the present application provides a triple film-forming water essence lipstick, which comprises, by weight:

[0006] Phenyl silicone oil: 30-45 parts, including at least one of diphenyl polydimethylsiloxane, trimethyl pentaphenyl trisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxyphenyl 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 alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, and the mass percentage of phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate in the lipstick is 1% to 10%;

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

[0009] Emulsifier: 0.5-5 parts, including at least one of lauryl PEG-10 tris(trimethylsiloxy)silylethyl dimethicone and lauryl PEG-9 polydimethylsiloxyethyl dimethicone;

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

[0011] Thickener: 0.1-0.5 parts, including stearalkonium chloride hectorite.

[0012] Without intending to be limited by any theory or explanation, in order to solve the problem that glossy lipstick is easy to stick to cups and lacks moist feeling, the inventor innovatively introduced a combination of three components, namely phenyl silicone oil, film-forming oil phase and film-forming water phase, into the lipstick formula. Among them, the film-forming oil phase and the film-forming water phase respectively contain an oil phase film former and a water phase film former, which can form an oil phase film layer and a water phase film layer respectively after the triple film-forming water essence lipstick is applied to the lips. As a result, the triple film-forming water essence lipstick can form a triple film-forming system of a water phase film layer, an oil phase film layer and a phenyl silicone oil layer on the surface of the lip skin. Among them, the water phase film layer has affinity with the lip skin due to its hydrophilicity and is formed on the surface of the lip skin; the phenyl silicone oil layer has the smallest polarity and easily migrates to the surface in contact with the air; the oil phase film layer has a neutral polarity and is formed between the water phase film layer and the phenyl silicone oil layer. The water-phase film layer contacts the lip skin and can provide a moisturizing feeling for the lip skin. In addition, other components in the water-phase film layer, such as additives, active substances, etc., can further enhance the moisturizing feeling of the lip skin and provide a certain degree of moisturizing and skin care effects. Under the action of the oil-phase film-forming agent and the oil-phase film-forming aid, other components of the oil phase, including the color powder, jointly form an oil-phase film layer to provide a coloring effect. Under the protection of the outermost phenyl silicone oil layer, when the lips applied with the triple film-forming water essence lipstick contact with a smooth object, only the surface phenyl silicone oil film will be left on the surface of the object, and the colorant in the middle layer will not be stained with the oil film on the surface of the object. In this way, the phenomenon of lipstick sticking to the cup and fading can be reduced. In the triple film-forming system, the oil-phase film-forming aid located in the middle layer is phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, and its unique water-holding property and viscosity control function promote the phase separation process between the three film layers, ensuring the realization of the non-stick effect and moisturizing effect.

[0013] Furthermore, the inventors found during the research and development process that it is difficult to compound phenyl silicone oil, film-forming oil phase and film-forming water phase. Due to the incompatibility of water and oil, demulsification is very likely to occur during the preparation of triple film-forming water essence lipstick, and "slag"-like substances are produced, and a stable emulsified system cannot be formed. After further curing, a stick-shaped lipstick with no surface defects (color bands on the surface or uneven surface) cannot be obtained. Faced with this dilemma, the inventors unexpectedly discovered after unremitting attempts that the compound use of the above-mentioned specific emulsifiers, dispersants and thickeners in this application can promote the stability of the triple film-forming water essence lipstick emulsification system, thereby preparing a triple film-forming water essence lipstick with a higher yield.

[0014] The triple film-forming water essence lipstick of the present application can not only provide hydration, moisturizing and skin care effects to the lips through the triple film-forming system, reduce the phenomenon of lipstick sticking to the cup and fading, but also ensure the quality stability in the production process through formula design, thereby achieving a high yield, which is conducive to the mass production of the triple film-forming water essence lipstick.

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

[0016] In any embodiment of the present application, the film-forming aqueous phase is 10 to 20 parts.

[0017] In any embodiment of the present application, the oil phase film former includes at least one of VP / hexadecene copolymer, VP / eicosene copolymer, phenylpropyldimethylsiloxysilicate, and acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer.

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

[0019] In any embodiment of the present application, the film-forming oil phase further includes oil, color powder and wax.

[0020] In any embodiment of the present application, the aqueous film-forming agent includes at least one of polyurethane-1 and acrylic (ester) copolymers.

[0021] In any embodiment of the present application, the film-forming water phase further comprises deionized water, polyols and active substances.

[0022] In any embodiment of the present application, the active ingredient is selected from MYROTHAMNUS FLABELLIFOLIA leaf / stem extract, acetylated sodium hyaluronate, sodium hyaluronate, sodium hyaluronate cross-linked polymer, hydrolyzed sodium hyaluronate, peony (PAEONIA SUFFRUTICOSA) seed oil, peony (PAEONIA SUFFRUTICOSA) root extract, squalane, aloe barbadensis (ALOE BARBADENSIS) leaf juice and collagen, or a mixture of several of them.

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

[0028] In any embodiment of the present application, preparing the mixed solution includes: mixing phase B and phase A uniformly, cooling to 75-80° C., adding an active substance and stirring uniformly to obtain a mixed solution. DETAILED DESCRIPTION

[0029] In order to make the application purpose, technical solution and beneficial technical effect of the present application clearer, the present application is further described in detail in conjunction with the embodiments below. It should be understood that the embodiments described in this specification are only for explaining the present application, not for limiting the present application.

[0030] For simplicity, this application only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form an unclearly recorded range; and any lower limit can be combined with other lower limits to form an unclearly recorded range, and any upper limit can be combined with any other upper limit to form an unclearly recorded range. In addition, although not clearly recorded, each point or single value between the range endpoints is included in the range. Thus, each point or single value can be combined with any other point or single value as its own lower limit or upper limit or with other lower limits or upper limits to form an unclearly recorded range.

[0031] In the description of the present application, it should be noted that, unless otherwise specified, “above” and “below” are inclusive of the number, and the “multiple” in “one or more” means two or more than two.

[0032] The above application content of the present application is not intended to describe each disclosed embodiment or each implementation in the present application. The following description more specifically illustrates exemplary embodiments. In many places throughout the application, guidance is provided by a series of examples, which can be used in various combinations. In each example, enumeration is only used as a representative group and should not be interpreted as exhaustive.

[0033] As described in the background art, the colorant in the glossy lipstick is soluble in the oil component. When the lips with the glossy lipstick come into contact with a smooth object (such as a glass cup, the back of the hand, etc.), the colorant in the lipstick is likely to remain on the surface of the smooth object together with the oil component, resulting in cup staining, color fading, etc. In addition, the traditional lipstick formula system only contains oil and wax components, which are incompatible with water. Therefore, the traditional lipstick formula system is usually free of water phase or contains a very small amount of water phase, resulting in a greasy feeling and lack of moisture.

[0034] In view of this, the inventors, after in-depth research and a large number of experiments, provide a triple film-forming water essence lipstick and a preparation method thereof.

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

[0036] In the triple film-forming water essence lipstick of the present application, the phenyl silicone oil includes at least one of diphenyl polydimethylsiloxane, trimethyl pentaphenyl trisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxyphenyl polydimethylsiloxane.

[0037] The film-forming oil phase includes an oil phase film-forming agent and an oil phase film-forming aid. Among them, the oil phase film-forming aid includes phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, and the mass percentage of phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate in the lipstick is 1% to 10%, for example, it can be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or within the range of any two of the above values. The above-mentioned oil phase film-forming agent can include any oil phase film-forming agent known in the art that can be used for lip makeup products. It is understandable that the film-forming oil phase can also include other oil phase components. Other oil phase components can include but are not limited to oil phase components of lip makeup products known in the art, such as grease, color powder, wax 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 phase components. The 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 phase components may include but are not limited to aqueous phase components known in the art that can be used in lip makeup products, such as deionized water, polyols, active ingredients, and other aqueous phase additives.

[0039] The emulsifier includes at least one of lauryl PEG-10 tris(trimethylsiloxy)silylethyl dimethicone and lauryl PEG-9 polydimethylsiloxyethyl dimethicone.

[0040] Dispersing agents include polyglyceryl-2 triisostearate.

[0041] Thickeners include stearalkonium hectorite.

[0042] Without intending to be limited by any theory or explanation, in order to solve the problem that glossy lipstick is easy to stick to cups and lacks moist feeling, the inventor innovatively introduced a combination of three components, namely phenyl silicone oil, film-forming oil phase and film-forming water phase, into the lipstick formula. Among them, the film-forming oil phase and the film-forming water phase respectively contain an oil phase film former and a water phase film former, which can form an oil phase film layer and a water phase film layer respectively after the triple film-forming water essence lipstick is applied to the lips. As a result, the triple film-forming water essence lipstick can form a triple film-forming system of a water phase film layer, an oil phase film layer and a phenyl silicone oil layer on the surface of the lip skin. Among them, the water phase film layer has affinity with the lip skin due to its hydrophilicity and is formed on the surface of the lip skin; the phenyl silicone oil layer has the smallest polarity and easily migrates to the surface in contact with the air; the oil phase film layer has a neutral polarity and is formed between the water phase film layer and the phenyl silicone oil layer. The water-phase film layer contacts the lip skin and can provide a moisturizing feeling for the lip skin. In addition, other components in the water-phase film layer, such as additives, active substances, etc., can further enhance the moisturizing feeling of the lip skin and provide a certain degree of moisturizing and skin care effects. Under the action of the oil-phase film-forming agent and the oil-phase film-forming aid, other components of the oil phase, including the color powder, jointly form an oil-phase film layer to provide a coloring effect. Under the protection of the outermost phenyl silicone oil layer, when the lips applied with the triple film-forming water essence lipstick contact with a smooth object, only the surface phenyl silicone oil film will be left on the surface of the object, and the colorant in the middle layer will not be stained with the oil film on the surface of the object. In this way, the phenomenon of lipstick sticking to the cup and fading can be reduced. In the triple film-forming system, the oil-phase film-forming aid located in the middle layer is phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, and its unique water-holding property and viscosity control function promote the phase separation process between the three film layers, ensuring the realization of the non-stick effect and moisturizing effect.

[0043] Furthermore, the inventors found during the research and development process that it is difficult to compound phenyl silicone oil, film-forming oil phase and film-forming water phase. Due to the incompatibility of water and oil, demulsification is very likely to occur during the preparation of triple film-forming water essence lipstick, and "slag"-like substances are produced, and a stable emulsified system cannot be formed. After further curing, a stick-shaped lipstick with no surface defects (color bands on the surface or uneven surface) cannot be obtained. Faced with this dilemma, the inventors unexpectedly discovered after unremitting attempts that the compound use of the above-mentioned specific emulsifiers, dispersants and thickeners in this application can promote the stability of the triple film-forming water essence lipstick emulsification system, thereby preparing a triple film-forming water essence lipstick with a higher yield.

[0044] The triple film-forming water essence lipstick of the present application can not only provide hydration, moisturizing and skin care effects to the lips through the triple film-forming system, reduce the phenomenon of lipstick sticking to the cup and fading, but also ensure the quality stability in the production process through formula design, thereby achieving a high yield, which is conducive to the mass production of the triple film-forming water essence lipstick.

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

[0046] Without intending to be limited by any theory or explanation, when the mass percentage of phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate in the triple film-forming water essence lipstick is within the above-mentioned appropriate range, on the one hand, the triple film-forming water essence lipstick can present a better glossy effect after application, making the lips visually more three-dimensional and plump, and 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 stable water phase content in the triple film-forming water essence lipstick system can reach 15 to 20 parts, thereby further enhancing the hydration and moisturizing degree of the triple film-forming water essence lipstick.

[0047] In some embodiments, the content of the film-forming aqueous phase may be 10 to 20 parts. For example, the content of the film-forming aqueous phase may be 10 parts, 12 parts, 15 parts, 18 parts, 20 parts, or within a range formed by any two of the above values.

[0048] In the above embodiment, the amount or ratio of each material in the triple film-forming water essence lipstick formula can be adjusted so that the stable water phase content in the triple film-forming water essence lipstick system can reach 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 alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate in the triple film-forming water essence lipstick.

[0049] According to the above implementation, the film-forming water phase in the triple film-forming water essence lipstick has a relatively high addition amount, which is beneficial to improving the hydration and moisturizing degree of the triple film-forming water essence lipstick.

[0050] In some embodiments, the oil phase film former may include at least one of VP / hexadecene copolymer, VP / eicosene copolymer, phenylpropyldimethylsiloxysilicate, and acrylates / 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 (0.1-0.5):1, for example, it can be 0.1:1, 0.2:1, 0.3:1, 0.4:1, 0.5:1, or within the range of any two of the above ratios.

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

[0053] The present application does not specifically limit the types of various conventional components such as oils, toners and waxes suitable for lip makeup products, and those skilled in the art can select appropriate types of oils, toners and waxes according to actual needs.

[0054] Exemplarily, the oil can be selected from at least one of hydrogenated rosinic acid methyl ester, octyldodecyl neopentanoate, isohexadecane, isododecane, polyglyceryl-2 triisostearate, diisostearyl malate, bis-diglyceryl polyacyl adipate-1, polyisobutene, dimer linoleyl dimer linoleate, polyglyceryl-2 isostearate / dimer linoleate copolymer, and phytosterol / octyldodecyl lauroyl glutamate.

[0056] Exemplarily, the wax may be selected from at least one of synthetic wax, polyethylene wax, microcrystalline wax, ozokerite 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 acrylic (ester) copolymers.

[0058] In some embodiments, the film-forming aqueous phase may further include deionized water, a polyol, and an active.

[0059] In some embodiments, the active ingredient can be selected from one or a mixture of 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] A second aspect of the present application provides a method for preparing a triple film-forming water essence lipstick, comprising the following steps S10 to S40.

[0061] S10, preparing phase A, comprising mixing phenyl silicone oil, film-forming oil phase, emulsifier, dispersant, and thickener, heating to 80-90° C., and stirring to obtain phase A.

[0062] In step S10, uniform stirring may mean that each component in phase A is substantially dissolved and uniformly dispersed to obtain a uniform dispersion system.

[0063] S20, preparing phase B, including stirring at least part of the components of the film-forming aqueous phase uniformly, heating to 80-90° C., to obtain phase B, at least part of the components including the aqueous phase film-forming agent and excluding active substances.

[0064] In step S20, at least part of the components of the film-forming aqueous phase may include components in the film-forming aqueous phase that can withstand a temperature of 80 to 90°C, for example, other components except the active substance. It is understood that when the components of the film-forming aqueous phase can all withstand a temperature of 80 to 90°C, step S20 may include stirring all the components of the film-forming aqueous phase uniformly and heating them to 80 to 90°C to obtain phase B. In one example, the temperature of phase B may be the same as that of phase A, so that there is no temperature difference between phase A and phase B, which is conducive to uniform mixing of phase A and phase B.

[0065] S30, preparing a mixed solution, including mixing phase B and phase A uniformly to obtain a mixed solution.

[0066] In step S30, phase B and phase A can be uniformly mixed 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 min to uniformly mix phase B and phase A.

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

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

[0069] According to the preparation method of the present application, through a specific formula design, the risk of demulsification can be reduced during the preparation of the triple film-forming water essence lipstick, a stable emulsification system can be formed, and a stick-shaped triple film-forming water essence lipstick with no surface defects can be obtained.

The prepared triple film-forming water essence lipstick can not only provide hydration, moisturizing and skin care effects for the lips through the triple film-forming system, reduce the phenomenon of lipstick sticking to the cup and fading, but also has high quality stability and yield.

[0070] In some embodiments, preparing the mixed solution may specifically include: mixing phase B and phase A uniformly, cooling to 75-80° C., adding active ingredients and stirring uniformly to obtain a mixed solution.

[0124] Test Section

[0125] (1) Cupping test

[0126] a. Smooth skin surface cup test

[0127] Apply lipstick paste to the subject's lips and immediately start a stopwatch. After 5 minutes, gently touch the lips with lipstick to the skin of the arm, then observe the marks on the skin and assess the degree of cup staining.

[0128] b. Glass surface cupping test

[0129] Apply lipstick paste to the subject's lips and immediately start a stopwatch to start timing. After 5 minutes, use a clear and clean glass cup to gently press the lips, then observe the marks on the cup and evaluate the degree of cup staining.

[0130] (2) Yield test

[0131] According to the formula and steps of each of the above embodiments and comparative examples, 20 lipsticks were prepared for each embodiment and comparative example. During the preparation process, observe whether the emulsification system has demulsification, stratification, oil or unevenness. After the preparation is completed, observe the morphology of the lipstick. If it is a solid with uniform texture and smooth surface, it is a qualified product, otherwise it is a defective product. Yield = number of qualified products / 20×100%.

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

[0133] Ten subjects with similar skin quality and age range were selected to reduce the impact of individual differences on the test results. Three different points were selected on the lips of each volunteer for testing. Using the stratum corneum moisture content test probe Corneometer CM825 (Courage-Khazaka, Germany) CU, the initial value of skin moisture was measured and recorded at each selected point. After measuring the initial moisture content, the subjects were asked to evenly apply a layer of lipstick sample on their lips. The amount and uniformity of application were controlled to ensure the consistency of the test. At different time points (immediately and 4h) after applying lipstick, the moisture content test probe was used again to measure and record the skin moisture content at each point, and the average value was taken as the skin moisture content at the corresponding time point. Based on the measured data, the skin moisture change rate at each point at different time points was calculated. The moisture change rate can be calculated by the following formula: Moisture change rate = (moisture content after using lipstick-initial moisture content) / initial moisture content × 100%.

[0134] The average value of the moisture change rate 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. The immediate moisture change rate was recorded as Q1, and the 4h 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 cup" may indicate that no sticking occurs in the smooth skin surface sticking cup test and the glass surface sticking cup test. "Sticking cup" may indicate that sticking occurs in both the smooth skin surface sticking cup test and the glass surface sticking cup test. In Table 2, " / " may indicate that the corresponding test was not performed. For example, the lipsticks of Comparative Examples 4-9 all had unqualified materials during the preparation process, and the finished lipsticks could not be prepared, so the sticking cup test, moisturizing and transepidermal water loss tests could not be performed.

[0141] From Table 1 and Table 2, it can be found that the triple film-forming water essence lipstick of the present application introduces phenyl silicone oil, film-forming oil phase and film-forming water phase into the lipstick formula, so that the triple film-forming water essence lipstick forms a triple film-forming system of water phase film layer, oil phase film layer and phenyl silicone oil layer on the surface of the lip skin. Thus, the prepared triple film-forming water essence lipstick is not only not easy to stick to the cup, but also has an excellent water light effect, which can effectively increase the hydration and moisturizing of the lip skin and make the lips fuller. In particular, in the triple film-forming water essence lipstick formula of Examples 1 to 21, the mass percentage of phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate 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 with Examples 22 to 23, the triple film-forming water essence lipstick of Examples 1 to 21 has better hydration and moisturizing effects. Moreover, the triple film-forming water essence lipstick of the present application can effectively reduce the risk of stratification, aggregation or demulsification of the emulsion system through the compound use of specific emulsifiers, dispersants and thickeners, so that the triple film-forming water essence lipstick has a better texture and appearance. Therefore, the yield rate of the triple film-forming water essence lipstick of Examples 1 to 23 can reach 100%.

[0142] In contrast, the lipstick formula of Comparative Example 1 does not add the oil phase film-forming aid phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, and other oil phase film-forming aids are used in the lipstick formulas of Comparative Examples 2 and 3. Therefore, after the lipsticks of Comparative Examples 1 to 3 are applied to the lip skin, they cannot achieve the triple film-forming effect of the aqueous film layer-oily film layer-phenyl silicone oil layer similar to the triple film-forming water essence lipstick of the present application. Therefore, after the lipsticks of Comparative Examples 1 to 3 are applied to the lip skin, the cupping phenomenon still occurs. In addition, the water phase content of the lipstick formulas of Comparative Examples 1 to 3 is similar to that of Examples 1 to 15, but the hydrating and moisturizing effects of the lipsticks of Comparative Examples 1 to 3 are significantly inferior to those of Examples 1 to 15. This further illustrates that in the triple film-forming system, the aqueous film layer in direct contact with the lip skin can effectively improve the hydration and moisturizing of the lip skin.

[0143] The lipstick formula of Comparative Example 4 does not add an emulsifier, and there is a relatively serious demulsification during the preparation process, the material body is stratified, and a uniformly mixed lipstick material body cannot be obtained. Although emulsifiers are added to the lipstick formulas of Comparative Examples 5 and 6, compared with lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethylsiloxane, other emulsifiers have limited stabilizing effects on the emulsified system and cannot be compounded with other materials to produce a synergistic effect, resulting in the phenomenon of oily lipstick body in the prepared lipstick body, and a uniformly mixed lipstick body cannot be obtained.

[0144] The lipstick formula of Comparative Example 7 does not add a dispersant. During the preparation process, it is difficult to mix the materials evenly, and a uniformly mixed lipstick material cannot be obtained. Although a dispersant is added to the lipstick formula of Comparative Example 8, compared with polyglycerol-2 triisostearate, other dispersants have poor dispersing effects on the materials and cannot be compounded with other materials to produce a synergistic effect. During the preparation process, it is still difficult to mix the materials evenly, and a uniformly mixed lipstick material cannot be obtained.

[0145] Although a thickener is added to the lipstick formula of Comparative Example 9, compared with stearalkonium chloride hectorite, other thickeners cannot be compounded with other materials to produce a synergistic effect, resulting in the final lipstick material body collapsing after cooling, and a formed lipstick cannot be produced.

[0146] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
