Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and in particular to a bicontinuous phase makeup remover gel and its preparation method. Background Technology

[0002] Currently, the market offers a wide variety of makeup removers, including cleansing water, cleansing oil, cleansing balm, and cleansing gel. Cleansing water feels refreshing on the skin, but its makeup removal effect is relatively weak; cleansing oil has excellent makeup removal ability, but it feels greasy on the skin and requires a large amount of emulsifiers, making it unsuitable for sensitive skin; cleansing balm has strong cleansing power, but it is more irritating to the skin and not very convenient to use; cleansing gel is gentle and refreshing, suitable for sensitive skin, but its cleansing ability is relatively weak.

[0003] In recent years, bicontinuous-phase makeup removers have gradually entered the cosmetics market. Bicontinuous-phase technology refers to the separation of oil and water phases into continuous phases. Makeup removers prepared using this technology can emulsify a large amount of oil with a small amount of emulsifier, and during rinsing, the extremely small particle size of the emulsions provides a refreshing, water-like feel. This technology holds the promise of breaking the current deadlock and achieving a better balance between makeup removal effectiveness, gentleness, and skin feel. However, in the formulation design of bicontinuous-phase makeup remover gels, most products rely on a traditional combination of surfactants, oils, preservatives, and water. Furthermore, to enhance the makeup removal ability, the amount of surfactant added is often increased, which undoubtedly increases the potential risk of skin irritation.

[0004] In conclusion, developing a makeup remover gel that balances cleansing power and gentleness has become an urgent technical challenge. Summary of the Invention

[0015] b) Mix the oils and fats to form phase B, then emulsify and homogenize phase A and phase B;

[0016] c) Add the preservative to the product of step b and mix well to obtain a bicontinuous phase makeup remover gel.

[0017] In one embodiment of this application, another method for preparing a bicontinuous phase makeup remover gel is provided, comprising the following steps:

[0018] a) At 60℃~80℃, the first emulsifier is dispersed in the deionized water, and then the polyol is added and mixed evenly. After the temperature drops to 25℃~30℃, the pH adjuster is added to adjust the pH value to 6.0~6.5 to obtain phase A;

[0025] The beneficial effects of this application are:

[0026] This application provides a bicontinuous phase makeup remover gel and its preparation method.

By selecting a naturally derived surfactant as the primary emulsifier in a small amount, and then adding polyols, oils, pH adjusters, preservatives, and deionized water, a bicontinuous phase makeup remover gel was prepared.

Furthermore, the bicontinuous phase makeup remover gel is a semi-transparent gel with a lightweight texture, easy to apply, and has a refreshing feel. Its pH value is close to that of the skin, providing excellent makeup removal while maintaining superior gentleness.

[0027] Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Detailed Implementation

[0028] The technical solutions of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0029] This application provides a bicontinuous phase makeup remover gel, comprising a first emulsifier of 1.5wt% to 2.5wt%, for example, the first emulsifier may be 1.5wt%, 1.7wt%, 1.9wt%, 2.2wt%, 2.3wt%, 2.5wt%, or any two of these values; and a second emulsifier of 0wt% to 0.6wt%, for example, the second emulsifier may be 0wt%, 0.2wt%, 0.3wt%, 0.4wt%, 0.5wt%, 0.6wt%, or any two of these values. The range of any two values; the third emulsifier 0wt%~1.4wt%, for example, the third emulsifier can be 0wt%, 0.2wt%, 0.3wt%, 0.4wt%, 0.5wt%, 0.6wt%, 0.8wt%, 1.0wt%, 1.2wt%, 1.4wt%, or any two of these values; the polyol 10wt%~20wt%, for example, the polyol can be 10wt%, 12wt%, 15wt%, 18wt%, 20wt%, or any other value. The following are possible values: 61 wt% to 78 wt% of oils / oils, for example, oils / oils can be 61 wt%, 65 wt%, 70 wt%, 78 wt%, or any two of these values; 0.2 wt% to 1.0 wt% of pH adjuster, for example, pH adjuster can be 0.2 wt%, 0.4 wt%, 0.6 wt%, 0.8 wt%, 1.0 wt%, or any two of these values; 0.4 wt% to 0.6 wt% of preservative, for example, preservative can be 0.4 wt%, 0.5 wt%, 0.6 wt%, or any two of these values; 2.0 wt% to 20.0 wt% of deionized water, for example, deionized water can be 2.0 wt%, 3.5 wt%, 9 wt%, 11 wt%, 13 wt%, 15 wt%, 20.0 wt%, or any two of these values; wherein, the first emulsifier is selected from at least one of sodium stearoyl glutamate and sodium stearoyl lactylate; the amounts of the second and third emulsifiers are not both 0.

[0030] Emulsifiers are amphiphilic molecules with both hydrophilic and lipophilic structures. They can adsorb at the oil-water interface and directly affect the appearance, stability, and skin feel of the system by regulating interfacial tension, electrostatic repulsion, and steric hindrance. Therefore, selecting a suitable emulsifier is one of the keys to constructing a stable emulsion system. Based on the characteristics of the emulsifier groups, they can be divided into anionic, cationic, and nonionic types. The inventors discovered that the first emulsifier is selected from sodium stearoyl glutamate and / or sodium stearoyl lactylate, which are anionic O / W (oil-in-water) emulsifiers. After ionization in water, the hydrophilic end carries a negative charge, causing the surface of the emulsion droplets to carry the same negative charge. By adsorbing counterions, a double electric layer is formed, generating electrostatic repulsion, which effectively prevents droplets from coalescing due to collision, thereby improving the stability of the system. Furthermore, sodium stearoyl glutamate and sodium stearoyl lactylate are naturally derived surfactants, which are milder and have highly efficient emulsifying properties, reducing the amount of emulsifier needed. However, the makeup remover gel obtained by adding only the first emulsifier will exhibit stratification.

[0031] The invention further reveals that the second emulsifier is selected from nonionic O / W emulsifiers, which have large hydrophilic groups (such as polyglycerol chains or PEG chains) and can form a thick hydration layer at the interface, preventing droplet aggregation through steric hindrance. The combined use of the first and second emulsifiers, combining the electrostatic repulsion of the anionic emulsifier with the steric hindrance of the nonionic emulsifier, forms a dual stabilization mechanism, significantly enhancing system stability. Simultaneously, the first emulsifier provides a mild foundation for the system, while the second emulsifier has low irritation; their synergy further improves the mildness and safety of the formulation.

[0032] The third emulsifier is selected from silicone-based emulsifiers, belonging to the W / O (water-in-oil) or W / Si (water dispersed in silicone oil) type. Its siloxane backbone has excellent compatibility with silicone oil, allowing it to deeply embed within silicone oil droplets and provide a strong anchoring effect, specifically designed to stabilize high-silicone-content systems. Simultaneously, its hydrophilic segments provide steric hindrance, further enhancing the stabilizing effect. The combined use of the first and third emulsifiers, through the synergistic effect of electrostatic stabilization and strong anchoring, can significantly improve the stability of high-silicone-content systems. This combination also provides a smooth, moisturizing feel to the system, enhancing the product experience. This application uses a first emulsifier as the main surfactant, and prepares a bicontinuous phase makeup remover gel with a second emulsifier and / or a third emulsifier, polyol, oil, pH adjuster, preservative, and deionized water as raw materials. The amount of each raw material is limited within the scope of this application. The resulting bicontinuous phase makeup remover gel has good stability and significantly reduces the amount of surfactant used compared to traditional makeup remover gels, thereby reducing the product's irritation. At the same time, it has excellent makeup removal ability and can effectively remove oil, dirt, and makeup residue from the skin surface. Its pH value is close to that of the skin, providing excellent makeup removal effect while also being very gentle. Furthermore, this bicontinuous phase makeup remover gel is a semi-transparent gel with a light texture, easy to apply, and has a refreshing feel on the skin.

[0033] In one embodiment of this application, the second emulsifier is selected from at least one of polyglycerol-10 laurate, PEG-7 glyceryl cocoate, and polyglycerol-6 caprylate; the third emulsifier is selected from at least one of cetyl PEG / PPG-10 / 1 polydimethylsiloxane and PEG-10 polydimethylsiloxane. Further research by the inventors revealed that the second emulsifier is an oil-in-water emulsifier, which can improve the stability and refreshing feel of the prepared bicontinuous-phase makeup remover gel system; the third emulsifier is a water-in-oil or W / Si emulsifier, which can provide excellent dissolving power for oil-soluble makeup in the prepared bicontinuous-phase makeup remover gel. The synergistic effect of the first, second, and third emulsifiers forms a unique "bicontinuous" gel structure that is neither entirely oil nor entirely water, resulting in a bicontinuous-phase makeup remover gel with better stability, gentler texture, refreshing and non-greasy feel, and excellent makeup removal efficacy.

[0034] In one embodiment of this application, based on the mass of the bicontinuous phase makeup remover gel, the mass percentage content of the second emulsifier is 0.2%-0.6%, for example, the mass percentage content of the second emulsifier can be 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, or any two of these values; the mass percentage content of the third emulsifier is 0.8%-1.4%, for example, the mass percentage content of the third emulsifier can be 0.8%, 1.0%, 1.2%, 1.4%, or any two of these values. By controlling the content of the second and third emulsifiers within the above ranges, the amount of surfactant used can be reduced, thereby reducing the irritation of the product and better balancing the makeup removal ability and gentleness of the makeup remover gel.

[0035] In one embodiment of this application, the polyol is selected from at least one of glycerin, sorbitol, and 1,3-butanediol. The bicontinuous-phase makeup remover gel includes polyols within the scope of this application, and controlling the amount of polyols within this scope is beneficial for controlling the solubility of oils in phase A and the miscibility between aqueous solutions and surfactants, thereby improving overall stability and system transparency.

[0036] In one embodiment of this application, the oil is selected from at least one of caprylic / capric triglyceride, ethylhexyl palmitate, cyclopentamethoxysiloxane, and isododecane. The bicontinuous-phase makeup remover gel includes oils within the scope of this application, and adjusting the amount of oil within this scope facilitates the formation of the bicontinuous phase, resulting in better stability.

[0037] In one embodiment of this application, the pH adjuster comprises citric acid and sodium citrate. The bicontinuous phase makeup remover gel includes a pH adjuster within the scope of this application, and the amount of the pH adjuster is controlled within the scope of this application. This facilitates adjusting the pH value of the bicontinuous phase makeup remover gel to be closer to that of the skin, resulting in a gentler and less irritating formula.

[0038] In one embodiment of this application, the preservative is selected from at least one of phenoxyethanol, 1,2-pentanediol, 1,2-hexanediol, and ethylhexylglycerin. The bicontinuous-phase makeup remover gel includes preservatives within the scope of this application, and the amount of preservative is controlled within the scope of this application to inhibit microbial growth in the bicontinuous-phase makeup remover gel, making it safer and more stable.

[0039] A second aspect of this application provides a method for preparing a bicontinuous phase makeup remover gel, comprising the following steps:

[0040] a) At 60℃~80℃, the first emulsifier is dispersed in the deionized water, then the second emulsifier and the polyol are added and mixed evenly. After the temperature drops to 25℃~30℃, the pH adjuster is added to adjust the pH value to 6.0~6.5 to obtain phase A; b) The oil mixture is used as phase B, and phase A and phase B are emulsified and homogenized; c) The preservative is added to the product of step b and mixed evenly to obtain a bicontinuous phase makeup remover gel.

[0041] In one embodiment of this application, a method for preparing a bicontinuous phase makeup remover gel includes the following steps: a) dispersing the first emulsifier in deionized water at 60°C to 80°C, then adding the polyol and mixing evenly; after the temperature drops to 25°C to 30°C, adding the pH adjuster to adjust the pH value to 6.0 to 6.5 to obtain phase A; b) mixing the third emulsifier with the oil evenly to obtain phase B, then emulsifying and homogenizing phase A and phase B; c) adding the preservative to the product of step b and mixing evenly to obtain the bicontinuous phase makeup remover gel.

[0042] In one embodiment of this application, a method for preparing a bicontinuous phase makeup remover gel includes the following steps: a) dispersing the first emulsifier in deionized water at 60°C to 80°C, then adding the second emulsifier and the polyol, mixing evenly, and after the temperature drops to 25°C to 30°C, adding the pH adjuster to adjust the pH value to 6.0 to 6.5 to obtain phase A; b) mixing the third emulsifier with the oil evenly to obtain phase B, then emulsifying and homogenizing phase A and phase B; c) adding the preservative to the product of step b, mixing evenly to obtain the bicontinuous phase makeup remover gel.

[0043] In this application, there are no particular limitations on the stirring time, emulsification, homogenization methods and times, as long as the purpose of this application can be achieved. For example, phase A and phase B can be emulsified for 10-30 minutes and homogenized for 5-8 minutes at a speed of 700 rpm to 1000 rpm.

The main indicators were scored, and the scoring criteria are shown in Table 3 below. The scoring results are the arithmetic mean of all volunteer scores, as shown in Table 4 below.

[0056] Example 1

[0057] This embodiment provides a bicontinuous phase makeup remover gel, whose raw materials, by mass percentage, include: 2% sodium stearoyl glutamate, 0.4% polyglycerol-6 caprylate, 15% glycerin, 69% oil (composed of 26% caprylic / capric triglyceride, 25% cyclopentamethoxysiloxane, and 18% isododecane), 0.25% sodium citrate, 0.35% citric acid, 0.46% phenoxyethanol, 0.04% ethylhexylglycerin, and the balance being water. The preparation method is as follows:

[0058] a) At 70°C, 4g of sodium stearoyl glutamate was dispersed in 25.4g of deionized water, and then 0.8g of polyglycerol-6 octanoate and 30g of glycerol were added and mixed evenly. When the temperature dropped to 25°C, the pH value was adjusted to 6.5 using 0.5g of sodium citrate and 0.7g of citric acid. The mixture was then mixed evenly to obtain phase A.

[0059] b) Mix phase A with 52g of caprylic / capric triglyceride, 50g of cyclopentamethoxydimethylsiloxane and 36g of isododecane to obtain phase B. Emulsify phase A and phase B at room temperature and 1000rpm for 25min and homogenize for 5min.

[0060] c) Add 0.92 g of phenoxyethanol and 0.08 g of ethylhexylglycerin to the product from step b, and mix thoroughly to obtain a semi-transparent gel-like bicontinuous phase makeup remover.

[0061] Examples 2-17

[0062] Except for adjusting the types and amounts of the formulation components according to Table 1, the rest is the same as in Example 1, and the preparation method is the same as in Example 1. In Example 13, the first emulsifier is prepared with sodium stearoyl glutamate and sodium stearoyl lactylate in a mass ratio of 1:1.

[0063] Comparative Examples 1-6

[0064] Except for adjusting the type and amount of emulsifier according to Table 1, the rest is the same as in Example 1. The preparation methods of Comparative Examples 1 to 6 are the same as in Example 1.

[0065] The preparation and performance parameters of each embodiment and comparative example are shown in Tables 1 to 4. In Table 1, A represents the content of the first emulsifier, B represents the content of the second emulsifier, C represents the content of the third emulsifier, and " / " indicates that the corresponding substance or parameter does not exist.

[0066] Table 1

[0067]

[0068] Table 2 Basic Performance

[0069]

[0070] According to Table 2, examples 1-17 and comparative examples 1-6 show that, within the scope of this application, the types and amounts of each component, when limited, result in a bicontinuous phase makeup remover gel with suitable viscosity and good centrifugal stability. The examples in this application pass high and low temperature stability tests, while the comparative examples show varying degrees of stratification. Examples 10-13 show that the type and amount of the first emulsifier affect the viscosity of the bicontinuous phase makeup remover gel; the viscosity initially increases and then decreases with increasing sodium stearoyl glutamate content. Examples 1 through 9 show that the use of the second and third emulsifiers improves the stability of the formulation. The second emulsifier also affects the transparency of the bicontinuous phase cleansing gel. When polyglycerol-6 octanoate is used as the second emulsifier, the transparency of the bicontinuous phase cleansing gel is better than that of polyglycerol-10 laurate and PEG-7 glyceryl cocoate. The third emulsifier slightly affects the viscosity of the bicontinuous phase cleansing gel. The viscosity of the bicontinuous phase cleansing gel prepared with cetyl PEG / PPG-10 / 1 polydimethylsiloxane is higher than that prepared with PEG-10 polydimethylsiloxane. Examples 10, 14, and 15 show that the oil content also affects the viscosity of the bicontinuous phase cleansing gel. Sodium stearoyl glutamate has high emulsifying properties and can emulsify higher amounts of added oil, thus improving the stability of the bicontinuous phase cleansing gel. Examples 10, 16, and 17 show that the type and amount of polyols added affect the stability of the bicontinuous phase cleansing gel. Polyols also affect the transparency of the appearance; when glycerin and sorbitol are used in a 1:1 ratio in this system, the bicontinuous phase cleansing gel has higher transparency. Comparative Examples 1, 5, and 6 show that without the first emulsifier or with an amount outside the scope of this application, the bicontinuous phase cleansing gel exhibits poor stability and layering. Comparative Examples 2 to 4 show that when sodium stearoyl glutamate or sodium stearoyl lactylate is used alone as an emulsifier, the prepared cleansing gel also has relatively poor stability, requiring the addition of a second and / or third emulsifier to stabilize the formulation.

[0071] Table 3 Scoring Criteria

[0072]

[0073] Table 4 Scoring Results

[0074]

[0075] The composition of the first emulsifier, second emulsifier, third emulsifier, and oils affects the makeup removal effect, rinsing ease, and post-use skin feel to varying degrees. Balancing makeup removal ability with gentleness is crucial. Table 4 shows that the bicontinuous-phase makeup remover gels prepared in Examples 1 to 17 of this application exhibit excellent makeup removal effects on lipsticks, are easy to rinse, and provide a gentle and refreshing feel, leaving the skin feeling neither tight nor overly oily after use. Comparative Examples 1 to 4 showed stratification, and their makeup removal effects were not tested. In Comparative Examples 5 and 6, the amount of the first emulsifier was outside the range of this application, resulting in makeup remover gels that either had poor makeup removal effects and insufficient moisturizing properties, or were too oily and heavy, making it difficult to achieve a good overall balance.

[0076] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
