Description

Technical Field

[0001] The present application relates to the field of cosmetics, and more specifically, to a novel colorful magnetic flat water-glossy cream and a preparation method thereof. Background Art

[0002] Currently, hydrating creams are a type of facial cosmetic that primarily moisturizes and brightens the skin. These creams on the market are typically all-oil based, primarily made from liquid paraffin, polyhydroxystearic acid, silicone oil, vegetable and synthetic oils, waxes, and pearlescent powder. They have a thick, smudge-like feel and are typically single-color, with aesthetics primarily influenced by packaging. For patterned hydrating creams, current technology relies primarily on specialized lamination equipment, requiring simultaneous filling of different colored materials. This not only places high demands on the equipment but also creates products prone to unclear patterns and distorted lines. Defective products are common, and since the materials cannot be recycled, losses typically exceed 200%, resulting in significant cost. Furthermore, batch consistency within a batch is very poor, with individual patterns often inconsistent across products. The resulting pattern is superficial, leaving the interior of the cream unpatterned after use. This significantly reduces product practicality. Summary of the Invention

[0003] In order to solve the above technical problems, the present application provides a new type of colorful magnetic flat water-glossy cream and a preparation method thereof.

[0004] In the first aspect, the present application provides a novel colorful magnetic flat water-brightening cream adopting the following technical solutions: A novel colorful magnetic flat water-glossy cream comprises the following raw materials in percentage by weight: 20-60% hydrogenated polyisobutylene, 10-55% isononyl isononanoate, 1-15% styrene / isoprene copolymer, 0.1-8% dextrin palmitate, 0.2-16% film-forming agent, 0.01-0.5% antioxidant, 0.1-1% preservative, 0.01-10% magnetic pearlescent agent, and 0.35-13% moisturizing agent.

[0005] By adopting the above technical solution, the use of hydrogenated polyisobutene and isononyl isononanoate as the base oil phase not only provides good ductility, making the water-brightening cream easier to spread and facilitating the dissolution and dispersion of other ingredients, but also possesses excellent moisturizing properties that allow for rapid absorption by the skin, resulting in a light, non-greasy texture. It also forms a protective film on the skin's surface, reducing moisture loss and keeping it soft and smooth. The combination of hydrogenated polyisobutene (high viscosity) and isononyl isononanoate (low viscosity) creates a gradient viscosity system, which not only ensures the plasticity of the cream but also provides a medium environment for the directional alignment of the magnetic pearlescent agent.

[0006] Using styrene / isoprene copolymer and dextrin palmitate as a composite thickener creates a three-dimensional mesh support structure. The styrene / isoprene copolymer forms a backbone through molecular chain entanglement, while dextrin palmitate forms a hydrogen-bonded network with the film-forming agent and humectant, synergistically enhancing the paste's storage stability. Strictly controlling the dosage of both components creates a dynamic viscoelastic system, allowing the paste's viscosity to rapidly decrease under shear (when applied) to facilitate application, and quickly regain its shape after standing. Dextrin palmitate also has a certain emulsifying effect, further helping to improve the product's uniformity and stability. The film-forming agent forms a transparent film on the skin's surface that not only locks in moisture and moisturizes, but also protects against external irritation and imparts a certain luster to the product. Application effectively enhances skin radiance. The humectant effectively replenishes and locks in moisture, increasing skin hydration and keeping it hydrated. These components work synergistically to adjust the texture and stability of the water-brightening cream while enhancing its moisturizing and brightening effects.

[0007] The above system is a wax-free system, which is based on transparent raw materials and is combined with a magnetic pearlescent agent with magnetic attraction. It can be filled through a mold with an iron magnet, inducing the directional arrangement of the magnetic pearlescent agent particles and changing their spatial arrangement. The formed pattern and texture can be unrestricted according to the mold shape. The filling equipment can be an ordinary filling machine. The obtained product formula, color and pattern lines are all unified, and the consistency of the same batch of products is high, with basically no defective products. It effectively solves the problems of unclear product patterns, uneven lines, and biased pattern lines. The production capacity and product stability are improved. The formula paste is transparent and stable. No matter how much the user applies, the color and line patterns are still visible in the paste, and the skin feel and makeup effect are good.

[0008] Preferably, the magnetic pearlescent agent is a mixture of synthetic fluorphlogopite, titanium dioxide, red iron oxide and tin oxide.

[0009] By employing this technical solution, synthetic fluorphlogopite possesses excellent gloss and reflective properties, creating a pearlescent effect that gives the water-based gloss cream a vibrant, iridescent visual effect. Titanium dioxide provides a certain degree of hiding power and gloss, red iron oxide imparts color, and tin oxide helps enhance the stability and brightness of the pearlescent. Specifically, the dosage of these components can be adjusted according to the product's color requirements. Furthermore, this combination of ingredients imparts magnetic attraction to the pearlescent, which can be used to arrange the pearlescent agent into a specific pattern or texture within the product. This creates a highly unique product, and regardless of how much the user applies, the color, lines, and texture remain uniform within the cream, making the product highly practical.

[0010] Preferably, the moisturizer is one or more of jojoba seed oil, coconut oil, squalane, phytosteryl oleate, and macadamia seed oil.

[0011] By adopting the above technical solutions, jojoba seed oil can regulate the skin's oil secretion, maintain the skin's moisture balance, and is easily absorbed by the skin, giving the skin a moisturized and light feeling. Coconut oil is rich in medium-chain fatty acids and has excellent moisturizing and hydrating effects. It also has certain antibacterial properties. Squalane is extremely skin-friendly and moisturizing, and can quickly penetrate into the skin to enhance the skin's barrier function. Phytosteryl oleate can reduce the skin's surface tension, improve the skin's moisturizing ability, and has certain soothing and repairing effects. Macadamia nut seed oil is rich in unsaturated fatty acids and vitamins, which can nourish the skin and increase its elasticity and radiance. The above ingredients work synergistically to replenish and lock in moisture for the skin from multiple aspects, increase the skin's water content, keep the skin hydrated, and increase the skin's radiance.

[0012] Preferably, based on 100% weight of the water-light cream, the moisturizer includes 0.1%-5% jojoba seed oil, 0.1%-5% coconut oil, 0.05%-1% squalane, 0.05%-1% phytosterol oleate, and 0.05%-1% macadamia seed oil.

[0013] By adopting the above technical solution, the dosage of each component is optimized to facilitate the construction of O / W microemulsion and reduce the skin water loss value.

[0014] Preferably, based on 100% by weight of the water-glossy cream, the film-forming agent includes 0.1%-8% of dibutyl ethylhexanoyl glutamine and 0.1%-8% of dibutyl lauroyl glutamine.

[0015] By adopting the above technical solution, dibutyl ethylhexanoyl glutamine and dibutyl lauroyl glutamine are selected as film-forming agents to form a semi-interpenetrating network, reduce the contact angle, improve skin adhesion, quickly form a thin film on the skin surface, lock in moisture, and play a good moisturizing role.

[0016] Preferably, the antioxidant is tocopherol acetate.

[0017] By adopting the above technical solution, tocopherol acetate has good antioxidant properties, which can prevent the oxidation of oil components during subsequent processing and storage, extend the shelf life of the product, and slow down skin aging.

[0018] Preferably, the preservative is one or both of phenoxyethanol and caprylyl glycol.

[0019] By adopting the above technical solution, the preservative can inhibit the growth and reproduction of microorganisms, ensure the safety and stability of the product during use, and prevent the product from deteriorating.

[0020] In a second aspect, the present application provides a method for preparing a novel colorful magnetic flat water-glossy cream, which adopts the following technical solution: A method for preparing a novel colorful magnetic flat water-glossy cream comprises the following steps: Heat and stir hydrogenated polyisobutylene, isononyl isononanoate, styrene / isoprene copolymer, dextrin palmitate and film-forming agent to obtain a phase A raw material; Add antioxidant and preservative to the phase A raw material and mix well to obtain the phase B raw material; Add magnetic pearlescent agent and moisturizing agent to the phase B raw material, mix and stir evenly, place in a mold with a magnet and fill in batches to obtain a water-glossy cream.

[0021] By adopting the above technical solution, the raw materials are added in batches and mixed at elevated temperature, which is conducive to the full mixing of the components and the suspension of the pearlescent color, so that the overall color has a diverse, layered, clear line and uniform texture line effect. By dispersing pearlescent powder with magnetic absorption properties in a transparent oil paste, and then using a mold with a magnet to migrate the magnetic pearlescent agent, different line patterns can be presented according to the pattern of the mold. The pattern is consistent from the surface to the lower layer, and the pattern remains clear after application, while giving the skin a good brightening and setting effect.

[0022] In summary, this application has the following beneficial effects: The water-glossy cream of the present application adopts a wax-free formula, based on transparent raw materials, and is combined with a magnetic pearlescent agent with magnetic attraction. It can be filled through a mold with an iron magnet, inducing the directional arrangement of the magnetic pearlescent agent particles and changing their spatial arrangement. The pattern formed can be shaped according to the mold without restrictions. The filling equipment can be an ordinary filling machine. The obtained product formula, color and pattern lines are unified, effectively solving the problems of unclear product patterns, uneven lines, and biased pattern lines. The production capacity and product stability are improved. The formula paste is transparent and stable. No matter how much the user applies, the color and line patterns are still visible in the paste. The product has a good skin feel and makeup effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 5 The difference from Example 1 is that the magnetic pearlescent agent is 3%, and the moisturizing agent is 11.5%, wherein the magnetic pearlescent agent includes 1% synthetic fluorphlogopite, 1% titanium dioxide and 1% red iron oxide; the moisturizing agent includes 5% jojoba seed oil, 4% coconut oil, 0.05% squalane, 0.4% phytosteryl oleate and 2.05% macadamia seed oil; the rest are the same as in Example 1.

[0035] Comparative Example Comparative Example 1 The difference from Example 1 is that synthetic fluorphlogopite is used to replace the magnetic pearlescent agent, and the rest is the same as Example 1.

[0036] Comparative Example 2 The difference from Example 1 is that the moisturizing agent is glycerin, and the rest is the same as Example 1.

[0037] Comparative Example 3 The difference from Example 1 is that isononyl isononanoate and dextrin palmitate are not added, and hydrogenated polyisobutylene is used to make up the difference. The other components are the same as those in Example 1.

[0038] Performance testing The water-brightening ointments prepared in Examples 1-5 and Comparative Examples 1-3 were subjected to high temperature (50°C), low temperature (-18°C) and cyclic stability tests for 90 days in accordance with QB / T 1857-2013. The temperature changes in the cyclic stability test were as follows: the product was placed at a temperature of -18°C and heated to 48°C at a rate of 3-5°C / min, then cooled to room temperature. The above operation was repeated in a cycle to observe the changes in the product. The results are shown in Table 2.

[0039] Table 2 Through Examples 1-5 and Table 2, it can be seen that the water-glossy cream obtained by the present application has excellent stability and does not change under high temperature, low temperature and hot and cold cycle conditions, while the changes in the raw material components or raw material amounts in Comparative Examples 1-3 cannot synergistically improve the stability of the product with other raw materials.

[0040] The moisturizing cream products obtained in Example 1 and Comparative Examples 1-3 were tested for moisturizing properties. Specifically, the moisturizing properties test was performed by inviting 50 volunteers to perform a makeup performance test. A skin tester was used to measure the skin moisture content of each volunteer immediately after applying the moisturizing cream and the facial moisture content 8 hours after applying the moisturizing cream. The rate of change in facial moisture content before and after application of the moisturizing cream was calculated: the 8-hour rate of change = the facial moisture content 8 hours after applying the moisturizing cream - the facial moisture content immediately after applying the moisturizing cream. The final average value was taken as the result and recorded in Table 3.

[0041] The makeup evaluation was specifically as follows: Skin adhesion: 10 points for smooth application, good shaping effect, and good skin adhesion; 10 points for moisturizing and brightening feeling: 10 points for moisturizing without being sticky, not drying out after application, and brightening the skin tone; the final average value was recorded as the result in Table 3.

[0042] Table 3 Change rate after 8 hours of application / % Skin adhesion / min Moisturizing and brightening feeling / min Example 1 18.1 9.68 9.75 Comparative Example 1 23.6 7.22 8.96 Comparative Example 2 38.4 8.01 7.45 Comparative Example 3 34.3 8.44 7.38 Through Example 2 and Comparative Examples 1-3 in combination with Table 3, it can be seen that the products obtained in Comparative Examples 1-3 have poor moisturizing effects and the overall makeup experience is also poor, while the product of Example 2 has excellent skin feel and makeup effect. This shows that the various raw material components of the present application cooperate with each other and complement each other, which can not only adjust the texture and stability of the water-light cream, but also enhance the moisturizing and brightening effects of the product.

[0043] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
