Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and more specifically, to an elastic pull-apart powder paste and its preparation method. Background Technology

[0002] Concealer can be considered a type of foundation. The difference is that concealer offers better coverage than regular foundation, adheres better to the skin, and is more long-lasting and less prone to fading. Everyone has imperfections on their face, and concealer can help restore a smooth and refined complexion. Concealers typically come in three forms: liquid, cream, and stick. "Patterned concealer" refers to a concealer product that has been designed with a swirl pattern.

[0003] Currently, most concealers focus on achieving a concealing effect. For example, patent application CN106726692 A discloses a concealer and its preparation method. This concealer includes glycerin, disodium EDTA, xanthan gum, magnesium sulfate, emollients, emulsifiers, stabilizers, colorants, lithium distearate dimethylammonium montmorillonite, preservatives, and water. The emollients are selected from cyclopentamethoxysilane, cyclohexylsiloxane, mineral oil, isononyl isononate, polydimethylsiloxane, butylene glycol dioctanoate / didecanoate, and polyglycerol-3 diisostearate. The emulsifier is selected from cetyl PEG / The formula consists of PPG-10 / 1 polydimethylsiloxane, PEG / PPG-15 / 15 polydimethylsiloxane, and sorbitan sesquioleate; stabilizers include lecithin, polyhydroxystearic acid, isopropyl myristate, ethylhexyl palmitate, isostearic acid, and polyglycerol-3 polyricinoleate; colorants include titanium dioxide, triethoxyoctylsilane, CI77492, CI77491, and CI77499; it provides even coloring and good concealing effect when applied.

[0004] Regarding the aforementioned technologies, the inventors believe that solely pursuing concealing effects will result in a poor makeup feel on the skin, affecting the user experience. Therefore, there is an urgent need to propose a solution to address these technical problems. Summary of the Invention

[0005] In order to achieve both concealing and a bouncy, jelly-like feel after applying concealer, this application provides an elastic, textured powder cream and its preparation method.

[0006] In a first aspect, this application provides an elastic flower-drawing powder paste, which adopts the following technical solution: A type of elastic styling powder, made from the following ingredients in parts by weight: 1-2 portions of Sanshanyu Essence; 1-2 parts synthetic wax; 0.8-1.6 parts of butyllauroyl glutamine; Mix 1-2 parts of thickener; Octyldodecyl alcohol 10-15 parts; Functional additive A: 10-40 parts; 3-6 parts of hydrogenated (styrene / methylstyrene / indene) copolymer; 1-10 parts of bis-behenol / isostearyl / phytosterol dimeric linoleic acid dimeric linoleate; 0.05-2 parts of VP / hexadecene copolymer; Functional additive B: 5-10 parts; 5-20 parts of polymethylsilsesquioxane; 0.5-20 parts silica; Antioxidant 0.01-0.5 parts; Antibacterial agent 0.2-2 parts; Colorant 5-50 parts; The efficacy adjuvant A is composed of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer in a weight ratio of (2-3):(1.8-2.2):1; The efficacy adjuvant B is composed of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate cross-linked polymer in a weight ratio of (4.6-5.8):1.

[0007] By adopting the above technical solutions, sunflower seed oil, as a natural base oil, can seamlessly blend with the skin, replenish the sebum film in the skin barrier, and repair the key stratum corneum in the skin barrier; caprylic / capric triglycerides have good spreadability, which can make the applied products even and delicate, and achieve good effects; styrene / butadiene copolymer has good film-forming properties; when sunflower seed oil, caprylic / capric triglycerides, and styrene / butadiene copolymer are used in a specific weight ratio to form functional adjuvant A, it can form a stable mixing medium with each component raw material and has excellent skin adhesion. Polydimethylsiloxane has a smooth and refreshing feel when applied to the skin, and it also has a good effect on increasing the skin's softness. The low surface tension of the polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer effectively smooths out wrinkles, resulting in a more natural makeup effect. When polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer are used in a specific weight ratio as functional adjuvant B, it can work synergistically with the other components, resulting in a product with a superior skin feel. Furthermore, this application combines functional adjuvants A and B, which complement each other and can stably combine with other components, resulting in an elastic, textured powder cream that provides both coverage and a bouncy, jelly-like feel, offering users an excellent experience.

[0008] Preferably, the efficacy adjuvant A is composed of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer in a weight ratio of 45:37:18.

[0009] By adopting the above technical solution, the functional additive A, composed of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer in the above weight ratio, has a relatively stable and excellent synergistic effect with functional additive B when applied. It achieves a concealing effect while exhibiting a relatively elastic skin feel, thereby making the elastic glitter powder cream have a high overall quality.

[0010] Preferably, the efficacy adjuvant B is composed of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer in a weight ratio of 84:16.

[0011] By adopting the above technical solution, the functional additive B composed of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer in the above weight ratio has a more stable and excellent synergistic effect with functional additive A when applied. It achieves a concealing effect while exhibiting a more elastic skin feel, thereby making the elastic glitter powder cream have a higher overall quality.

[0012] Preferably, the weight ratio of the efficacy adjuvant A to the efficacy adjuvant B is 3:1.

[0013] By adopting the above technical solution, when the above-mentioned weight ratio of functional additives A and B are used together, they can not only form a uniform and stable combination with other raw materials, but also work together to exert a better effect. As a result, the elastic flower powder cream can achieve concealing while exhibiting a more bouncy skin feel after application, and the overall quality is better.

[0014] Preferably, the mixed thickener is a composition of at least two of hydrogenated (styrene / isoprene) copolymer, pentaerythritol tetra(bis-tert-butylhydroxyhydrogenated cinnamic acid) ester, lauryl alcohol polyoxyethylene ether, and coconut oil diethanolamide.

[0015] By adopting the above technical solutions, the above-mentioned thickeners can improve the stability, increase the viscosity, and change the rheological morphology of elastic pull flower powder paste when applied. The use of two or more thickeners can meet the needs of other raw materials with more components, making the entire mixing system more stable. In particular, it plays an important role in the combination and stabilization of the effects of functional additives A and B, thereby making the obtained elastic pull flower powder paste have higher quality.

[0016] Preferably, the antioxidant is one or a combination of several of tocopheryl acetate, squalane, glutathione, nicotinamide, anthocyanins, and tea polyphenols.

[0017] By adopting the above technical solution, the oil components are oxidized and deteriorated by factors such as air, moisture, and sunlight. The resulting peroxides, acids, aldehydes and other harmful substances can irritate the skin and affect the user experience. The antioxidants mentioned above can be evenly dispersed among the raw materials of each component and protect the oil components, thereby ensuring that the elastic crepe powder has a good and stable application effect.

[0018] By adopting the above technical solutions, the above-mentioned antibacterial agents can play an excellent role in inhibiting the growth of microorganisms in the mixed system of elastic lace powder paste, thereby maintaining the stability of the properties of elastic lace powder paste, making it less prone to deterioration after opening and use, and ensuring that elastic lace powder paste has excellent and stable application quality.

[0019] Preferably, the colorant is one or a combination of several of CI 77891, CI 77492, CI 77491 and CI 77499.

[0020] By adopting the above technical solutions, the above-mentioned colorants can be fully dispersed among the other component raw materials, and can be selected and matched according to actual needs to obtain elastic pull flower powder paste with various colors.

[0021] Secondly, this application provides a method for preparing elastic pull-apart powder paste, which adopts the following technical solution: A method for preparing an elastic pull-apart powder paste includes the following steps: (1) Prepare raw materials according to the formula, including tri-behendine, synthetic wax, dibutyllauroyl glutamine, mixed thickener, octyl dodecanol, functional additive A, hydrogenated (styrene / methylstyrene / indene) copolymer, bis-behendine / isostearyl / phytosterol di-linoleyl alcohol di-linoleate, VP / hexadecene copolymer, functional additive B, polymethyl silsesquioxane, silica, antioxidant, antibacterial agent and colorant; (2) Heat and mix the mixed thickener, dibutyllauroyl glutamyl and octyl dodecanol in step (1) until uniform, then add sanshenhexene, synthetic wax, hydrogenated (styrene / methylstyrene / indene) copolymer, bis-benzyl alcohol / isostearyl alcohol / phytosterol dipolylinoleyl alcohol dipolylinoleate, VP / hexadecene copolymer, heat and keep warm to mix uniformly to obtain mixed oil base; (3) After mixing and grinding the mixed oil base and colorant in step (2), add functional additive A, functional additive B, polymethylsilsesquioxane and silica, heat and mix evenly, then add antioxidant and antibacterial agent, mix evenly and pour into packaging material, finally perform lace forming, and after cooling and setting, you can get elastic lace powder paste.

[0022] By adopting the above technical solution, the preparation method is simple to operate and easy to mass-produce. Furthermore, the sequential addition and mixing of the components facilitates quality control during the process, resulting in a high-quality and stable elastic floral makeup powder. Specifically, adding functional additives A and B, polymethylsilsesquioxane, and silica after grinding avoids damage to the raw materials in functional additives A and B during the grinding process. This ensures that the elastic floral makeup powder provides both coverage and a bouncy, jelly-like texture after application.

[0023] In summary, this application has the following beneficial effects: This application uses functional additive A, which is composed of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer in a specific weight ratio, and functional additive B, which is composed of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer in a specific weight ratio. Through the synergistic effect of the two, the resulting elastic floral powder cream can achieve concealing effect while having a jelly-like bouncy skin feel after application, providing users with an excellent experience.

[0062] Performance testing

[0063] Test samples: The elastic flower-making powder paste obtained in Examples 1-2, 4-15, and 17 was used as test samples 1-2, 4-15, and 17, and the elastic flower-making powder paste obtained in Comparative Examples 1-19 was used as control samples 1-19.

[0064] Experimental Methods: 180 volunteers aged 18-45 years were randomly selected and randomly divided into 36 groups of 5 people each. 34 groups of volunteers used experimental samples 1-2, 4-15, and 17, and control samples 1-19, respectively. The treatment was administered once daily, with the face cleansed with water before each use, for one week. After each use, volunteers rated the concealing effect and the skin's elasticity, according to the scoring criteria below. The average daily scores for the week were recorded as the volunteer scores. The average scores of the 5 volunteers in each group were recorded as the scores for each experimental sample and control sample, as shown in Table 2 below.

[0065] The concealing effect is rated as follows: There are many minor flaws and the uniformity is poor. 0-3 points (inclusive) Minor imperfections are common, but the uniformity is poor. 3-5 points (inclusive) Minor imperfections are few, and uniformity is average. 5-8 points (inclusive) Minor imperfections are few or absent, and the uniformity is good. 8-10 points The skin-feel rating is as follows: Poor skin feel and lack of elasticity. 0-3 points (inclusive) Poor skin feel, average elasticity 3-5 points (inclusive) The skin feel is average, and the elasticity is average. 5-8 points (inclusive) It has a good skin feel and good elasticity. 8-10 points Table 2. Test results of test samples 1-2, 4-15, 17 and control sample 1-19 Test sample 1 8.84 9.34 Test sample 2 8.71 9.18 Test sample 4 9.18 9.67 Test sample 5 9.05 9.58 Test sample 6 8.97 9.55 Test sample 7 8.74 9.25 Test sample 8 8.81 9.31 Test sample 9 8.72 9.24 Test sample 10 8.75 9.20 Test sample 11 8.80 9.28 Test sample 12 8.89 9.26 Test sample 13 8.51 9.01 Test sample 14 8.42 8.94 Test sample 15 8.82 9.30 Test sample 17 8.88 9.29 Control sample 1 5.98 6.85 Control sample 2 5.89 6.91 Control sample 3 4.27 5.49 Control sample 4 7.27 7.80 Control sample 5 7.34 7.82 Control sample 6 7.20 7.76 Control sample 7 7.12 7.71 Control sample 8 7.24 7.78 Control sample 9 7.18 7.74 Control sample 10 6.74 7.45 Control sample 11 6.71 7.40 Control sample 12 6.85 7.52 Control sample 13 6.43 7.21 Control sample 14 6.40 7.16 Control sample 15 6.29 7.09 Control sample 16 7.25 7.84 Control sample 17 7.22 7.81 Control sample 18 6.51 7.34 Control sample 19 6.60 7.47 Based on Examples 1-2 and Comparative Examples 1-3, and referring to Table 2, it can be seen that the combination of functional additive A and functional additive B brings about an excellent synergistic effect, resulting in an elastic floral powder cream that not only has excellent and stable concealing effect but also provides an excellent bouncy skin feel. While using functional additive A or functional additive B alone effectively improves both concealing effect and bouncy skin feel, the effect is far less superior than that of the combination. Furthermore, based on Examples 4-6 and Table 2, it can be seen that when the weight ratio of functional additive A to functional additive B is 3:1, the combined effect is relatively excellent and stable. However, when the ratio is lower or higher than this, the concealing effect and bouncy skin feel of the elastic floral powder cream are slightly inferior.

[0066] Based on Examples 1, 7-9, and Comparative Examples 4-9, and in conjunction with Table 2, it can be seen that the efficacy adjuvant A, composed of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer in a weight ratio of (2-3):(1.8-2.2):1, exhibits superior and stable efficacy, resulting in a better concealing effect and a bouncy skin feel when the elastic flower powder cream is applied. The effect is most excellent when the weight ratio of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer is 45:37:18. When any one or two of these ingredients exceed the above dosage range, the concealing effect score and bouncy skin feel score of the elastic flower powder cream will significantly decrease. Furthermore, by combining Comparative Examples 10-15 and Table 2, it can be seen that using any one or two of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer as efficacy adjuvant A cannot produce a significant effect when combined with efficacy adjuvant B. Therefore, the combination of sunflower seed oil, caprylic / capric triglyceride, and styrene / butadiene copolymer is particularly important for obtaining high-quality elastic pull flower powder paste.

[0067] Based on Examples 1, 10-12, and Comparative Examples 16-17, and in conjunction with Table 2, it can be seen that the efficacy additive B, composed of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer in a weight ratio of (4.6-5.8):1, exhibits superior and stable efficacy, resulting in a better concealing effect and a bouncy skin feel when the elastic floral powder cream is applied. The effect is most excellent when the weight ratio of polydimethylsiloxane to polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer is 84:16. When the amount of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymer exceeds the above range, the concealing effect score and bouncy skin feel score of the elastic floral powder cream significantly decrease. Combined with Comparative Examples 18-19 and Table 2, it can be seen that using any one or both of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymers as functional additive B cannot produce significant effects when combined with functional additive A. Therefore, the combination of polydimethylsiloxane and polydimethylsiloxane / vinyltrimethylsiloxysilicate crosspolymers is particularly important for obtaining high-quality elastic glitter powder paste.
