Description

Technical Field

[0001] This application relates to the field of color cosmetics, and more specifically, to a bubble gel makeup primer and its preparation method. Background Technology

[0002] As an important component of the cosmetics industry, makeup primers have experienced rapid growth in recent years. They not only protect the skin but also provide moisturizing and even-toned skin, laying a solid foundation for subsequent makeup steps. With consumers' increasing demands for makeup effects and skincare, the research and development of makeup primers has become a hot topic in the industry. Their diversification and functionality continuously meet market needs, driving technological progress and innovation throughout the cosmetics industry.

[0003] Currently, makeup primers on the market suffer from a significant lack of variety in their formulations, with common formulations including pure water, oil-in-water (O / W), and water-in-oil (W / O). However, each of these traditional formulations has its own limitations: Pure water formulation: Pure water formulations achieve basic moisturizing effects through a simple mixture of water-soluble ingredients. However, this type of makeup primer has fewer options for functional powders in its raw material selection. For example, ingredients like silicone elastomer gels, which significantly enhance the soft-focus effect, are difficult to utilize effectively in pure water formulations, resulting in a less noticeable soft-focus effect and failing to meet consumers' demands for a smooth, refined skin appearance.

[0004] Oil-in-water and water-in-oil formulations: These two types of makeup primers require the addition of emulsifiers during the manufacturing process to ensure that the oil and water phases can be evenly mixed to moisturize the skin. However, emulsifiers themselves can be irritating to the skin, especially for people with sensitive skin. Using makeup primers containing emulsifiers may cause skin allergies, itching, and other discomfort, limiting the applicability of these products.

[0005] Given the aforementioned shortcomings of existing makeup primers, there is an urgent market demand for developing a new type of makeup primer and its preparation method. Summary of the Invention

[0006] This application provides a bubble gel makeup primer product and its preparation method. By adopting a special process and unique raw material combination, this application forms a new bubble gel-type makeup primer product. This new formulation not only enriches the range of raw materials that can be used, but also effectively improves the performance of the product, bringing consumers a richer skin feel experience, while enhancing the fun and overall experience of the makeup process, and meeting the market demand for high-quality, innovative makeup primer products.

[0007] Firstly, the bubble gel makeup primer provided in this application adopts the following technical solution: A bubble gel makeup primer product comprises the following raw materials in weight percentages: methyl methacrylate crosspolymer 2-4%, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosspolymer 2-4%, polymethylsilsesquioxane 1-3%, amino-terminated polydimethylsiloxane 0.1-0.3%, synthetic wax 0.6-0.9%, non-volatile oil-based emollient 6-12.5%, skin feel modifier 1-3%, pH adjuster 0.07-0.1%, colorant 0.002-0.16%, p-hydroxyacetophenone 0.4-0.6%, tocopheryl acetate 0.1-0.5%, thickener 0.1-0.4%, moisturizer 6.5-15%, and water as the balance; The non-volatile oil-based emollients include at least two of the following: isononyl isononanoate, jojoba seed oil, sunflower seed oil, meadowfoam seed oil, and hydrogenated polydecene.

[0008] By employing the above technical solutions, methyl methacrylate crosslinking polymers, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosslinking polymers, and polymethylsilsesquioxane form a three-dimensional network structure, giving the gel a transparent texture while absorbing oil, filling pores and fine lines, improving skin texture, and making the skin surface smoother. Amino-terminated polydimethylsiloxanes, through interfacial tension regulation, enhance the interfacial tension between oil droplets and the aqueous phase, improving the water resistance and stability of the oil droplets, stabilizing their morphology, and preventing deformation, aggregation, or breakage during processing and stirring, thus facilitating the formation of a uniform and aesthetically pleasing spherical appearance. The formulation of non-volatile oil-based emollients provides a soft, moisturizing feel, nourishes the skin, and offers long-lasting hydration. Synergistically with skin feel modifiers, it reduces stickiness, balances refreshingness and moisturizing properties, and improves spreadability and film-forming speed. Colorants give the product a unique color appearance, adding visual interest.

[0009] This application utilizes a specific ratio of methyl methacrylate cross-linked polymers and vinyl polydimethylsiloxane / polymethylsiloxane-sesquioxane cross-linked polymers to form a gel-like base that suspends purple oil droplets, providing both soft-focus, oil-controlling, and moisturizing functions. Synthetic waxes and amino-terminated polydimethylsiloxanes synergistically enhance the stability of the oil droplets, ensuring uniform distribution during processing and improving both the product's appeal and functionality. The overall formula achieves multiple benefits for a makeup primer, including minimizing pores, moisturizing and controlling oil, soothing the skin, and enhancing the makeup experience.

[0010] Preferably, by weight percentage, the non-volatile oily emollient comprises 6-9% isononyl isononanoate, 0.01-0.5% jojoba seed oil, 0.01-0.5% sunflower seed oil, 0.01-0.5% meadowfoam seed oil, and 0.1-2% hydrogenated polydecene.

[0011] Through experimental research using the above technical solutions, it was found that the addition amount of isononyl isononanoate in non-volatile oil-based emollients is 6-9%. Its small molecular weight and strong permeability not only give the skin a light feel but also quickly form a protective film, reducing moisture loss and effectively moisturizing the skin while improving product spreadability. The addition amounts of jojoba seed oil, sunflower seed oil, and meadowfoam seed oil are 0.01-0.5%, providing natural antioxidant and soothing effects, avoiding the skin irritation caused by traditional emollients, and playing a moisturizing and nourishing role, repairing the skin barrier, and improving skin feel.

[0012] Hydrogenated polydecene can further enhance the moisturizing effect of the product, while synergistically improving the hardness of oil droplets, enhancing the shear resistance of oil droplets, improving the suspension stability of oil droplets, and facilitating the uniform distribution of oil droplets in the system.

[0013] The synergistic effect of these components in a well-balanced ratio gives the product excellent moisturizing properties and a comfortable user experience, while also improving its spreadability and hydration.

[0014] Preferably, the skin feel modifier includes at least one of polydimethylsiloxane, cyclopentadimethylsiloxane, and polysiloxane-11.

[0015] By adopting the above technical solutions and optimizing the composition of the skin feel modifier, the skin feel of the product can be effectively adjusted, and the soft-focus effect and oil control performance of the product can be improved. Among them, polydimethylsiloxane can reduce the surface friction coefficient, improve the product's spreadability, and bring a refreshing and non-sticky user experience; cyclopentadimethylsiloxane accelerates the product's drying and film-forming speed, reduces shine, and further enhances the skin's refreshing feeling; polysiloxane-11 helps to fill fine lines, improve skin texture, visually blur pores, and make the skin appear smoother and more even.

[0016] Preferably, based on 100% skin feel modifier, the skin feel modifier comprises 40-50% polydimethylsiloxane, 32-45% cyclopentadimethylsiloxane, and the balance polysiloxane-11.

[0017] By adopting the above technical solutions and optimizing the composition ratio of the skin feel modifier, the product can effectively improve the skin feel during use, achieving the effects of oil control, soft focus, and filling in fine lines.

[0018] Preferably, the pH adjuster is an aminomethylpropanol solution.

[0019] Furthermore, the mass concentration of the aminomethylpropanol solution is 90-95 wt%.

[0020] By employing the above technical solution and using aminomethylpropanol solution as a pH adjuster, the product's pH can be precisely adjusted, ensuring the thickener performs optimally within its pH range. This facilitates full swelling of the thickener, enhances the system's viscoelasticity, improves gel stability, and avoids skin irritation, thereby improving product stability and skin feel. Furthermore, the use of aminomethylpropanol solution helps optimize the compatibility of various ingredients in the formulation, further enhancing the overall performance of the product.

[0021] Preferably, the thickener includes one or both of xanthan gum and carbomer.

[0022] Preferably, the thickener comprises 0.01-0.1% xanthan gum and 0.14-0.18% carbomer by weight.

[0023] By adopting the above technical solution, xanthan gum and carbomer are compounded in a specific ratio. The synergistic effect of the two helps to form a more uniform gel network structure, assists in film formation, improves the thixotropy of the product, and forms a shear-thinning gel system. This ensures the product's fluidity while rapidly thickening during application, ensuring that the product maintains a uniform texture and a good application experience during use, improving the skin feel, and enhancing overall stability. This prevents the product from separating or settling during storage, prevents oil droplet sedimentation, enhances the suspension stability of oil droplets in the system, and results in a more uniform distribution of oil droplets, further improving the product's visual appeal and usability.

[0024] Preferably, the moisturizer comprises 6-10% butylene glycol, 0.5-1% 1,2-hexanediol, 0.1-2% nicotinamide, and 0.1-1% panthenol.

[0025] By employing the above technical solutions, butylene glycol in the moisturizer enhances the product's moisturizing ability and improves its stability under low-temperature conditions; 1,2-hexanediol further enhances the moisturizing effect and also has a certain antibacterial effect, helping to extend the product's shelf life; niacinamide penetrates deep into the skin's layers, providing long-lasting moisturizing and soothing effects, and improving skin texture; panthenol forms a protective film on the skin surface, locking in moisture and reducing water loss. Butylene glycol and 1,2-hexanediol form a polyol moisturizing system, synergistically strengthening the skin barrier repair function with niacinamide and panthenol, giving the product excellent moisturizing performance and meeting consumers' needs for moisturizing functions in pre-makeup primers.

[0026] Preferably, the colorant includes at least one of CI 60725 and CI 77007.

[0027] By adopting the above technical solution, the addition of CI 60725 and CI 77007 can adjust the appearance color of the oil phase and give the oil droplets a vivid color appearance. Generally, the amount of CI 60725 is 0.001-0.002%, and the amount of CI 77007 is 0.001-0.015%, which can make the product present a unique purple oil droplet visual effect and enhance the product's interest and attractiveness.

[0028] Secondly, this application provides a method for preparing a bubble gel makeup primer, which adopts the following technical solution: A method for preparing a bubble gel makeup primer involves heating and mixing a moisturizer, thickener, p-hydroxyacetophenone, and water until homogeneous, adding a pH adjuster and stirring until homogeneous, and keeping it warm to obtain an aqueous phase raw material. The amount of pH adjuster added is 20-35% of its total amount. A methyl methacrylate crosspolymer, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosspolymer, polymethylsilsesquioxane, non-volatile oil-based emollients, colorants, and tocopheryl acetate are homogenized, then heated and mixed with synthetic wax and ammonia-terminated polydimethylsiloxane until homogeneous to obtain an oil phase raw material. Continue stirring the aqueous phase material, add the oil phase material to the aqueous phase material, control the stirring speed at 200-220 rpm to control the size of the oil droplets, and after the target oil droplet size is formed, slow down the stirring speed and cool down. When the temperature drops to 40-50℃, add the remaining pH adjuster, stir evenly, and then discharge the material.

[0029] Furthermore, during the preparation of the aqueous raw materials, the temperature is raised to 70-80℃, the stirring speed is 300-500 rpm, and the time is 2-5 minutes.

[0030] Furthermore, during the preparation of the oil phase raw materials, the homogenization rate is 3000-4000 rpm, and the temperature is raised to 70-80℃ while stirring.

[0031] By employing the above technical solution, the homogeneity and stability of the aqueous phase raw materials are ensured through heating and mixing of the humectant, thickener, p-hydroxyacetophenone, and water, providing a foundation for the subsequent formation of oil droplets. By adding a pH adjuster and controlling its addition amount to 20-35% of the total, the acid-base environment of the aqueous phase raw materials is optimized. The stepwise addition of the pH adjuster avoids localized over-acidity / over-alkaliness that could damage the gel structure, enhances the performance of the thickener, and improves the overall stability of the product.

[0032] In the preparation of oil phase raw materials, high-speed homogenization is used to facilitate the formation of tiny oil droplets. The combined use of non-volatile oil-based emollients, synthetic waxes, and amino-terminated polydimethylsiloxanes enhances the water resistance, hardness, and shear resistance of the oil droplets, maintains their spherical appearance, and prevents them from deforming or agglomerating during stirring. By controlling the stirring speed to 200-220 rpm, the size of the oil droplets is precisely adjusted to ensure that the product has a beautiful appearance and uniform texture. After the target oil droplet size is formed, the stirring speed is slowed down to reduce shear force and prevent the oil droplets from being damaged, ensuring that the product has a uniform appearance and stable function.

[0033] 6. Add the remaining pH adjuster during the cooling process to further optimize the acid-base balance of the product and ensure the stability and effectiveness of the final product.

[0034] In summary, this application has the following beneficial effects: This application utilizes a unique combination of raw materials to form a gel-like base and suspend oil droplets, creating a distinctive bubble-gel texture. This allows the makeup primer to combine soft-focus, oil-control, and moisturizing functions, meeting users' multi-functional needs for makeup primers and breaking through the limitations of traditional single-form formulations. Combined with specific process steps, through reasonable temperature control, precise adjustment of stirring speed, and optimization of the order of component addition, the stability of the oil droplets and product performance are balanced, enhancing the fun and overall experience of the makeup process.

[0048] Performance testing The oil control effect of the makeup primer samples prepared in Examples 1-6 and Comparative Examples 1-3 was tested. The specific experimental steps are as follows: 20 healthy volunteers (aged 18-35, with combination to oily skin, meeting the requirements of CB / T27861-2011 "Guidelines for Safety Evaluation of Cosmetics") were selected. All skin care products were discontinued 12 hours before the experiment, and the volunteers were allowed to adapt for 30 minutes in a constant temperature and humidity environment (25±2℃, relative humidity 50±5%).

[0049] The amount of sebum secreted on both sides of the nose of volunteers was measured using a Sebumeter SM815 sebometer (measured in parallel 3 times, and the average value was recorded as T0).

[0050] At 0.5 mg / cm 2 Apply the product to the sample and measure sebum levels at 2 hours (T2), 4 hours (T4), and 6 hours (T6) after application. Calculate the 6-hour sebum reduction rate: Sebum reduction rate = (T0 - T6) / T0 × 100% The results are recorded in Table 2.

[0051] The moisturizing effects of the makeup primer samples prepared in Examples 1-6 and Comparative Examples 1-3 were tested. The specific experimental steps are as follows: Twenty healthy volunteers (aged 18-35, with dry to combination skin) were selected. They stopped using skincare products 24 hours before the experiment and adapted for 30 minutes in a constant temperature and humidity environment (25±2℃, relative humidity 50±5%).

[0052] The moisture content of the stratum corneum of the inner forearm of volunteers was measured using a Corneometer CM825 skin moisture meter (measured in triplicate, and the average value was recorded as T0).

[0053] At 0.5 mg / cm 2 Apply the product to the sample and measure the moisture content repeatedly at 1 h (T1), 4 h (T4), and 8 h (T8) after application. Calculate the 8-hour moisture increase rate: Moisture increase rate = (T8 - T0) / T0 × 100% The results are recorded in Table 2.

[0054] Makeup application effect tests were conducted on the makeup primer samples prepared in Examples 1-6 and Comparative Examples 1-3. The specific experimental steps are as follows: Sensory evaluation: 30 professional evaluators (with more than 5 years of experience in makeup evaluation) scored the samples according to "adhesion (1-5 points, 5 points = no caking), pore coverage (1-5 points, 5 points = pores are completely invisible), and 6-hour makeup lasting power (1-5 points, 5 points = no makeup fading)" and the average score was taken (rounded to one decimal place).

[0055] The pre-makeup primer samples prepared in Examples 1-6 and Comparative Examples 1-3 were subjected to oil droplet stability tests. The specific steps are as follows: Centrifugation stability: Centrifuge at 3000 rpm for 30 minutes and observe the oil droplet stratification (rating from 0 to 5, with 0 indicating no stratification).

[0056] High and low temperature cycling: 3 cycles of 24 hours each at -5℃ / 25℃ / 50℃, and record the oil droplet deformation rate (measure the average deformation ratio of 100 oil droplets under a microscope).

[0057] Table 2 Through Examples 1-6 and in conjunction with Table 2 and Figure 1 As can be seen, the bubble gel makeup primer obtained by this application forms a gel-like base and suspends purple oil droplets, which has the functions of soft focus, oil control and moisturizing. Example 1 is the optimal formula, with a stable three-dimensional network structure and uniform oil droplet suspension, achieving synergistic effect of "oil control-moisturizing-makeup".

[0058] As can be seen from Example 1 and Comparative Example 1, combined with Table 2, in Comparative Example 1, there was an excess of methyl methacrylate cross-linked polymer and insufficient synthetic wax. The gel was too dry, resulting in a decrease in oil control / moisturization. The oil droplets agglomerated due to the excessive ammonia-terminated polydimethylsiloxane, which significantly reduced stability.

[0059] As can be seen from Example 1 and Comparative Example 2, and in conjunction with Table 2, Comparative Example 2 uses a single type of non-volatile oil, a single type of skin feel modifier, and a different type of thickener, resulting in poor skin feel and stability.

[0060] As can be seen from Example 1 and Comparative Example 3, and in conjunction with Table 1: In Comparative Example 3, there was no synthetic wax and ammonia-terminated polydimethylsiloxane, and the oil droplets lost their interfacial tension regulation. After centrifugation / high and low temperatures, they were severely aggregated, but the basic oil control / moisturizing effect was still partially retained due to the normality of other raw materials.

[0061] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

When the temperature drops to 40-50℃, add the remaining pH adjuster, stir evenly, and then discharge the material.
