Description

Technical Field

[0001] The present application relates to the field of cosmetic technology, and further to the field of color cosmetic technology, and specifically to a nourishing and hydrating three-color lipstick and a preparation method thereof. Background Art

[0002] Lip makeup is an important part of color cosmetics, mainly covering lip care and modification products, including lipstick, lip gloss, lip glaze, lip mud, etc. These products meet consumers' needs for lip beauty and care through coloring, moisturizing and modifying functions. At first, lipstick was mainly made of natural oils and pigments, with a single color and texture. With the advancement of the chemical industry, the application of synthetic pigments and fragrances has made lipstick more colorful and more delicate in texture. Today, the rise of the Internet and social media has promoted the rapid development of the market, and consumers' demand for personalized, healthy and environmentally friendly products is growing.

[0003] Three-color lipstick is a lipstick that contains three colors in one tube. Through different application methods, it can be easily combined to create a variety of makeup effects, such as bitten lip makeup, gradient makeup, etc. This design not only meets consumers' demand for diverse makeup, but also reduces the trouble of carrying multiple lipsticks. Therefore, it is very popular in the market; Currently, most of the same type of multi-color lipstick formulas on the market mainly use talcum powder, silicone oil, silicone powder, nylon powder, PMMA, synthetic oils and other raw materials. Among them, talcum powder comes from natural minerals, but it is usually accompanied by the risk of asbestos. Nylon and PMMA are derived from plastics, which are non-degradable and not very friendly to the environment. At the same time, it is easy for the color matching to be poor, resulting in color mixing or dislocation during the color matching process of the paste, and even after the splicing is completed, it is easy for the mold to stick and crack. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a moisturizing three-color lipstick and a preparation method thereof, aiming to ensure that the product is safe and harmless to the environment and human body and the stability of the paste when the colors are mixed, to ensure that the three colors are clearly separated in the paste, to avoid problems such as color mixing, dislocation or mold cracking, and to improve the appearance quality and aesthetics of the product.

[0005] In the first aspect, the present application provides a moisturizing three-color lipstick using the following technical solutions: A moisturizing and hydrating three-color lipstick, the preparation raw materials of which include: Phase A: Pentaerythritol Tetraisostearate 10-30%; Diisostearyl Malate 10-30%; Polyglyceryl-2 Triisostearate 8-15%; Tridecyl Trimellitate 10-19%; Bis-Diglyceryl Polyacyladipate-2, 5-11%; Film former 8-40%; Phenyl Trimethicone 10-19%; Bis-PEG-15 Methyl Ether Polydimethicone 0.1-1%, Emollient 0.1-5%; Skin feel regulator 1-5%; Phase B: antioxidant 0.01-0.5%; preservative 0.1-1%; Phase C: colorant 0.5-3%; Phase D: humectant 0.1-1%; emollient humectant 0.2-2%; The film-forming agent is composed of paraffin wax and synthetic wax, and the weight ratio of paraffin wax to synthetic wax is (3-4):1; Among them, the ratio of the amount of bis-PEG-15 methyl ether polydimethylsiloxane to the total amount of pentaerythritol tetraisostearate, diisostearyl malate, polyglyceryl-2 triisostearate, tridecyl trimellitate, and bis-diglyceryl polyacyl adipate-2 is 1:(300-350).

[0006] Furthermore, the emollient and moisturizing agent is selected from at least one of phytosteryl oleate, cocoa seed butter, and sodium hyaluronate.

[0007] Furthermore, the skin feel regulator is castor oil isostearate succinate.

[0008] Furthermore, the antioxidant is tocopherol acetate; and the preservative is a combination of phenoxyethanol and caprylyl glycol.

[0009] Furthermore, the moisturizing agent is rose hydrosol.

[0010] Furthermore, the colorant consists of CI 77891, CI 77492, CI 77499, CI 15850, CI 17200 and CI 16035 in a weight ratio of (1-3): 1:1:1:1:1.

[0011] By adopting the above technical solution, the moisturizing three-color lipstick provided by the present application not only achieves the effects of paste stability and clear color separation, but also has moisturizing properties, so that the lips remain moisturized for a long time after using the lipstick, meeting the needs of modern consumers for high-quality, healthy and environmentally friendly products.

[0012] The reason may be that, as a silicone compound, bis-PEG-15 methyl ether polydimethylsiloxane has good lubricity and dispersibility. In the lipstick formula, it can effectively improve the fluidity and application performance of the paste. When the ratio of the amount of bis-PEG-15 methyl ether polydimethylsiloxane in phase A to the sum of the amounts of pentaerythritol tetraisostearate, diisostearyl malate, polyglyceryl-2 triisostearate, tridecyl trimellitate, and bis-diglyceryl polyacyl adipate-2 meets the ratio of 1:(300-350), a thin lubricating layer is formed inside the paste. This lubricating layer helps to reduce the direct contact and mutual penetration between pastes of different colors, and can form a relatively stable barrier at the color interface, effectively preventing the mixing and diffusion of colors, thereby maintaining clear separation of colors. In addition, bis-PEG-15 methyl ether polydimethicone has good compatibility and dispersibility with pentaerythritol tetraisostearate, diisostearyl malate, polyglyceryl-2 triisostearate, tridecyl trimellitate, and bis-diglyceryl polyacyl adipate-2, which effectively improves the fluidity of the paste and reduces the color accumulation and mixing caused by uneven paste. Thanks to the combined effect of interface stabilization, fluidity regulation, compatibility and dispersibility, the three colors are finally evenly distributed in the paste and clearly separated, greatly reducing color bleeding, dislocation, mold sticking and cracking.

[0013] In a second aspect, the present application provides a method for preparing a moisturizing tri-color lipstick using the following technical solution: A method for preparing a moisturizing and hydrating three-color lipstick comprises the following steps: S1. Weigh all the raw materials of phase A and heat them in a unified container at 90±5℃ to dissolve. Stir evenly after they are fully dissolved. Then continue to add the raw materials of phase B and adjust the temperature to 85±5℃. Stir evenly to obtain the premix. S2, divide the raw materials in phase C into three parts, grind them evenly with a three-roll grinder, adjust three colors, and then add them together with the raw materials of phase D to the premix obtained in S1, stir evenly to obtain a paste raw material; S3, filling the paste raw material obtained in S2 with corresponding packaging materials and molds, and obtaining the paste after cooling.

[0014] Preferably, the filling temperature of the paste raw material in S3 is 65-70°C.

[0015] By adopting the above technical scheme, the preparation method not only ensures the stability and quality of the product, but also improves production efficiency, meets the needs of modern consumers for high-quality, personalized products, and at the same time, pays attention to environmental protection and safety, and most of the environmentally friendly and degradable raw materials are selected, which basically complies with the concept of sustainable development.

[0016] In summary, this application has the following beneficial effects: 1. The present application successfully achieves the stability of the paste and clear color separation by selecting specific component raw materials, especially controlling the ratio of bis-PEG-15 methyl ether polydimethylsiloxane to other ester components in phase A, which effectively reduces problems such as color bleeding, dislocation or mold cracking, and greatly improves the appearance quality and aesthetics of the product. At the same time, good stability and color separation also extend the service life of the product, allowing consumers to enjoy high-quality makeup effects for a longer period of time; 2. The moisturizing tricolor lipstick in this application not only focuses on color stability and aesthetics, but also emphasizes moisturizing and emollient properties. By adding emollients such as phytosteryl oleate, cocoa seed butter, sodium hyaluronate, and moisturizers such as rose water, the lipstick can keep the lips moisturized for a long time after application, effectively relieving dryness and tightness of the lips. This dual effect of moisturizing and emollient makes the product more in line with the needs of modern consumers for healthy and comfortable makeup; 3. In terms of preparation method, this application adopts an efficient and environmentally friendly production process. Through precise temperature control and fine grinding and color adjustment steps, the stability and quality of the product are ensured. Most of the raw materials are environmentally friendly and degradable materials, which is in line with the concept of sustainable development. This efficient and environmentally friendly production process not only improves production efficiency, but also reduces pollution to the environment, providing consumers with safer and healthier product choices.

[0024] The lipsticks prepared in Examples 1-3 and Comparative Examples 1-2 were used as samples, and performance tests were performed on them according to the aforementioned performance test. The test results are as follows.

[0025] Table 2: Performance test results of samples obtained from Examples 1-3 and Comparative Examples 1-2 As can be seen from the above table, the lipstick samples prepared by Examples 1-3 passed the heat resistance and cold resistance performance required in the physical and chemical performance test, and in the sensory test, no color bleeding, misalignment, mold sticking and cracking were found after the color matching was completed. While the lipstick samples prepared by Comparative Examples 1-2, although they passed the heat resistance and cold resistance performance test, in the sensory test, color bleeding and misalignment were obviously found after the color matching was completed; This may be that in Comparative Example 1, the ratio of bis-PEG-15 methyl ether polydimethylsiloxane to the total amount of other ester ingredients is 1:250, indicating that the silicone oil content is too high or the ester content is too low; while in Comparative Example 2, the ratio reaches 1:400, reflecting that the silicone oil content is too low or the ester content is too high. Both of these imbalances may weaken the compatibility between the ingredients and the fluidity inside the paste, which may cause the lubricating layer interface originally formed by bis-PEG-15 methyl ether polydimethylsiloxane to become unstable, causing the color to diffuse, and thus observing undesirable phenomena such as color bleeding and dislocation in the sensory test.

[0026] Example 4 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that the use of a film-forming agent as one of the raw materials used in phase A is different, the film-forming agent is composed of paraffin wax and synthetic wax, and the weight ratio of paraffin wax to synthetic wax is 4:1.

[0027] Comparative Example 3 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that the use of a film-forming agent as one of the raw materials used in phase A is different, the film-forming agent is composed of paraffin wax and synthetic wax, and the weight ratio of paraffin wax to synthetic wax is 2:1.

[0028] Comparative Example 4 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that the use of a film-forming agent as one of the raw materials used in phase A is different, the film-forming agent is composed of paraffin wax and synthetic wax, and the weight ratio of paraffin wax to synthetic wax is 5:1.

[0029] Comparative Example 5 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that the use of a film-forming agent as one of the raw materials used in phase A is different, the film-forming agent is composed of ozokerite and microcrystalline wax, and the weight ratio of ozokerite to microcrystalline wax is 3:1.

[0030] The lipsticks prepared in Example 4 and Comparative Examples 3-5 were used as samples, and performance tests were performed on them according to the aforementioned performance test. The test results are as follows.

[0031] Table 3: Performance test results of samples obtained in Example 4 and Comparative Examples 3-5 As can be seen from the above table, the lipstick sample prepared by Example 4 has excellent appearance, color and smell, and passes the heat resistance and cold resistance required in the physical and chemical performance test; while the lipstick samples prepared by Comparative Examples 3-5 all pass the cold resistance and heat resistance tests, but the performance in the sensory test decreases to varying degrees; The mass ratio of paraffin wax to synthetic wax in the film-forming agent used in the lipstick sample prepared in Comparative Example 3 is 2:1, resulting in a relatively high content of synthetic wax, which makes it impossible to form a stable and uniform lubricating layer, affecting the lubricity and color uniformity of the lipstick. The mass ratio of paraffin wax to synthetic wax in the film-forming agent used in the lipstick sample prepared in Comparative Example 4 is 5:1, which is much higher than 3:1 in Example 1, resulting in the lipstick being slightly brittle and hard, resulting in cracking in some areas, and the excessively high paraffin content also affects its color uniformity and stability, resulting in a little color bleeding and misalignment. In Comparative Example 5, the film-forming agent of the lipstick uses an equal amount of ozokerite and microcrystalline wax to replace the original paraffin wax and synthetic wax respectively. However, this change caused some problems in the test, specifically, the lipstick showed mold cracking and slight color bleeding. This may be due to the physical properties of ozokerite and microcrystalline wax, such as melting point, hardness or viscosity, not matching with other ingredients in the lipstick, resulting in the internal structure of the lipstick becoming unstable during the cooling or solidification process. In addition, ozokerite and microcrystalline wax may be insufficiently compatible with other components in the lipstick formula, which may cause stress concentration at the interface between the components, and ultimately cause cracks to form on the surface of the lipstick, resulting in color bleeding.

[0032] Comparative Example 6 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that an equal amount of ethylhexyl palmitate is used in place of pentaerythritol tetraisostearate in the raw material for preparing phase A.

[0033] Comparative Example 7 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that an equal amount of isononyl cetearyl ester is used in place of diisostearyl malate in the raw material preparation of phase A.

[0034] Comparative Example 8 A nourishing and moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that an equal amount of isotridecyl isononanoate is used in the raw material preparation of phase A instead of polyglyceryl-2 triisostearate.

[0035] Comparative Example 9 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that an equal amount of neopentyl glycol dicaprylate / dicaprate is used in the raw material preparation of phase A to replace polytridecanol trimellitate.

[0036] Comparative Example 10 A moisturizing three-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that an equal amount of diisostearyl dimer linoleate is used in the raw material preparation of phase A to replace di-diglycerol polyacyl adipate.

[0037] Comparative Example 11 A moisturizing tri-color lipstick, the preparation method of which is basically the same as that of Example 1, the only difference being that in the raw materials for preparing phase A, equal amounts of diisostearyl dimer linoleate and neopentyl glycol dicaprylate / dicaprate are used to replace bis-diglycerol polyacyl adipate and tridecyl alcohol trimellitate, respectively.

[0038] The lipsticks prepared in Comparative Examples 6-11 were used as samples, and performance tests were performed on them according to the aforementioned performance test. The test results are as follows.

[0039] Table 4: Performance test results of samples obtained in Comparative Examples 6-11 In the comparative example 6, ethylhexyl palmitate is used to replace the pentaerythritol tetraisostearate in the phase A emollient ingredients in an equal amount, and in the comparative example 7, isononyl cetearyl stearate is used to replace the diisostearyl malate in the phase A emollient ingredients in an equal amount, and in the comparative example 8, isotridecyl isononanoate is used to replace the polyglyceryl-2 triisostearate in the phase A emollient ingredients in an equal amount, and in the comparative example 9, neopentyl glycol dicaprylate / dicaprate is used to replace the tridecanol trimellitate in the phase A emollient ingredients in an equal amount, and in the comparative example 10, diisostearyl dimer linoleic acid is used to replace the bis-diglyceryl polyacyl adipate-2 in the phase A emollient ingredients in an equal amount, and in the comparative example 11, neopentyl glycol dicaprylate / dicaprate and diisostearyl dimer linoleic acid are used to replace the tridecanol trimellitate and bis-diglyceryl polyacyl adipate-2 in the phase A emollient ingredients in an equal amount, respectively; It can be seen from the test results in the above table that the lipstick samples prepared by Comparative Examples 6-11 all passed the cold resistance and heat resistance tests, but their appearance and color in the sensory test showed different degrees of performance degradation, and most of them had color bleeding. At the same time, the appearance of the paste was greasy and rough, and accompanied by pores; This indicates that the emollient in phase A composed of pentaerythritol tetraisostearate, diisostearyl malate, polyglyceryl-2 triisostearate, tridecyl trimellitate, and bis-diglyceryl polyacyl adipate-2, has a synergistic effect with bis-PEG-15 methyl ether polydimethylsiloxane and a film-forming agent composed of paraffin and synthetic wax in a mass ratio of (3-4):1, which jointly determine the sensory properties and stability of the lipstick.

[0040] The above are all modifications without creative contribution or solutions that obviously constitute technical inspiration that can be made to the present embodiment as needed by technical personnel in this field after reading this specification, but they should be protected by patent law as long as they are within the scope of the claims of this application.
