Description

Technical Field

[0001] The present application relates to the field of lipstick processing, and more specifically, to a moisturizing and silky lipstick and a preparation process thereof. Background Art

[0002] Lipstick is one of the commonly used cosmetics and can be made into different colors to meet people's daily needs.

[0003] In autumn and winter, lipstick is prone to drying out. After being applied to the lips, it is easy to deepen the lip lines and cause the lips to become dry and cracked. Lipstick generally requires a good touch and ductility to ensure a smoother application process and reduce pulling and sticking. At the same time, in order to prolong the durability of the makeup, the lipstick needs to have good color saturation and durability. Even if it is wet by drinking water or being rained on, it is not easy for the lipstick to change color or fall off, thus having the advantage of keeping the makeup intact for a long time.

[0004] Therefore, how to prepare a lipstick that is moisturizing, nourishing, has high color saturation, good durability and good waterproofness is a problem to be solved. Summary of the Invention

[0005] In order to provide a lipstick that is moisturizing, nourishing, has high color saturation, good durability and good waterproofness, the present application provides a moisturizing silky lipstick and a preparation process thereof.

[0006] In a first aspect, the present application provides a moisturizing and silky lipstick, which adopts the following technical solution: A moisturizing and silky lipstick comprises the following raw materials in percentage by weight: 12-18% pentaerythritol tetraisostearate, 9-15% ethylhexyl palmitate, 10-15% bis-diglyceryl polyacyl adipate-2, 9-15% caprylic / capric triglyceride, 8-12% octyldodecanol, 6-8% ozokerite, 5-8% polyethylene wax, 1-3% beeswax, 1.5-2% candelilla wax, 0.5-1% preservative, 0.1-0.3% antioxidant, 0.05-0.15% avocado butter, 0.05-0.15% macadamia nut seed oil, 0.05-0.15% phytosterols, and 19.85-21.15% colorant.

[0007] By adopting the above technical solution, pentaerythritol tetraisostearate can evenly disperse the colorant and improve the color saturation of the lipstick; combined with ethylhexyl palmitate, bis-diglyceryl polyacyl adipate-2 and caprylic triglyceride as the humectant in the lipstick, the moisturizing and wetting effect of the lipstick can be improved; combined with the moisturizing effect of avocado tree butter and macadamia nut seed oil on the lips, the palmitic acid, stearic acid and other substances contained therein can moisturize the lips and increase skin elasticity, thereby further improving the moisturizing effect through the moisturizing effect, making it less likely for the lips to become dry and cracked after long-term use of the lipstick, improving the color durability of the lipstick while having a long-term moisturizing and hydrating effect.

[0008] Pentaerythritol tetraisostearate, ethylhexyl palmitate, bis-diglyceryl polyacyladipate-2 and caprylic triglyceride combined with octyldodecanol and phytosterols improve the lubricity of the lipstick. While the colorant is evenly dispersed, the lipstick has good ductility during the application process, allowing the color to be evenly applied to the lip surface. Combined with octyldodecanol, it has a certain thickening effect, which can improve the color fastness and durability of the lipstick on the lip surface.

[0009] The combination of ozokerite, polyethylene wax, beeswax and candelilla wax can improve the plastic effect of lipstick while ensuring its waterproofness, making it less likely for lipstick to fade due to rain, and improving the color durability and waterproofness of lipstick.

[0010] Preferably, the preservative is phenoxyethanol.

[0011] By adopting the above technical solution, phenoxyethanol is added as a preservative in lipstick, which can extend the shelf life of lipstick and effectively kill bacteria and molds to prevent cross-infection of bacteria and molds; at the same time, phenoxyethanol has good solubility and penetration, which facilitates the uniform mixing of various ingredients in lipstick and can also increase the ductility and stability of lipstick.

[0012] Preferably, the antioxidant is tocopherol acetate.

[0013] By adopting the above technical solution, tocopherol acetate is a derivative of vitamin E, which has strong antioxidant ability. Adding tocopherol acetate to lipstick can effectively protect the lip skin from damage by free radicals and slow down the skin aging process.

[0014] Tocopheryl acetate can strengthen the connection between skin cells and interstitial matrix, reduce water loss, and increase the skin's water retention capacity. Adding this ingredient to lipstick can help keep the lip skin moisturized and prevent dryness and cracking.

[0015] Preferably, the colorant comprises the following raw materials in the following weight percentages: 16.85-17.55% CI 77891, 2.0-2.5% CI 15850, 0.6-0.8% CI 16035, and 0.2-0.5% CI 19140.

[0016] By adopting the technical solution, the lipstick is bright in color and has high saturation.

[0017] Preferably, the CI 77891 is loaded CI 77891, and the loaded CI 77891 is prepared from CI 77891, polyethylene glycol solution and hydroxyapatite particles in a mass ratio of 1:0.1-0.25:0.05-0.1.

[0018] By adopting the above technical solution, CI 77891 is titanium dioxide, which has a concealing effect, can improve the fineness of the lips, and enhance the whitening effect and glossiness of the lipstick. At the same time, it can also improve the durability of the lipstick on the lip surface and reduce discoloration.

[0019] Titanium dioxide, hydroxyapatite particles, and polyethylene glycol solution are combined. The viscosity of the polyethylene glycol solution is used to adhere the hydroxyapatite particles to the surface of titanium dioxide. The barrier effect of the hydroxyapatite particles is used to minimize direct contact of titanium dioxide with the lip skin, which may cause allergic reactions in users. The polyethylene glycol solution adsorbed on the surface of the hydroxyapatite particles allows pentaerythritol tetraisostearate, ethylhexyl palmitate, bis-diglyceryl polyacyladipate-2, and caprylic triglyceride to be combined with the polar hydroxyl and carboxyl groups in octyldodecanol and phytosterols to easily connect with the carrier CI 77891, thereby improving the dispersion uniformity and stability of the color powder in the lipstick and the color durability of the lipstick on the lip surface. Hydroxyapatite has a certain glossiness, which can increase the glossiness and fullness of the colorant. At the same time, the connection between hydroxyapatite particles, octyldodecanol, and polyethylene glycol can further improve the fineness and ductility of the lipstick.

[0020] Preferably, the average particle size of the hydroxyapatite particles is 3-5 μm.

[0021] By adopting the above technical solution, the particle size of hydroxyapatite particles is limited, ensuring that hydroxyapatite is evenly and stably attached to the lip surface, thereby improving the gloss, saturation, fineness and adhesion durability of the lipstick on the lip surface.

[0022] Preferably, the CI 15850 is loaded CI 15850, and the loaded CI 15850 is prepared from CI 15850, acetyl glucosamine solution and citric acid fatty acid glyceride in a mass ratio of 1:0.1-0.2:0.1-0.2.

[0023] By adopting the above technical solution, acetyl glucosamine utilizes its viscosity to facilitate the adhesion of powdered granular citric acid fatty acid glyceride to the surface of the red color powder of CI 15850. The amino and carboxyl groups in acetyl glucosamine are connected with the hydrophilic carboxyl groups in citric acid fatty acid glyceride, thereby facilitating the connection of the red color powder with citric acid fatty acid glyceride. The hydrophobic group of citric acid fatty acid glyceride attracts and connects with the hydrophobic agents in pentaerythritol tetraisostearate, ethylhexyl palmitate, bis-diglyceryl polyacyl adipate-2 and caprylic triglyceride, thereby improving the dispersibility and stability of CI 15850 in the lipstick, thereby improving the color durability.

[0024] Acetyl glucosamine, polyethylene glycol, and macadamia nut seed oil have good moisturizing and emollient effects. On the surface where lipstick contacts the skin, they enhance their own moisturizing effect, making the lips less prone to dryness and cracks. They can also block direct contact between the colorant's color powder and the skin, minimizing sensitivity issues.

[0025] Preferably, the candelilla wax is modified candelilla wax, which is prepared from candelilla wax liquid and coconut wax in a mass ratio of 1:0.1-0.24.

[0026] By adopting the above technical solution, the combination of candelilla wax and coconut wax can balance the plasticity and flexibility of lipstick. Candelilla wax makes lipstick hard and has a good plasticity effect, but has poor softness. Coconut wax is compatible with candelilla resin. The softening effect of coconut wax is utilized to improve the softness and plasticity of the modified candelilla wax, thereby ensuring the quality of the lipstick. In addition, coconut wax has good glossiness, which can further improve the glossiness of the lipstick; at the same time, it can also improve the moisturizing property of the lipstick.

[0027] Preferably, the phytosterols consist of β-sitosterol and campesterol in a mass ratio of 1:0.5-1.

[0028] By adopting the above technical solution, β-sitosterol and campesterol are combined. β-sitosterol can reduce the irritation of lipstick to sensitive skin. Campesterol has a certain anti-inflammatory effect, and combined with β-sitosterol, it further soothes the lips. Both β-sitosterol and campesterol have good water-locking and moisturizing effects, which can prevent dryness and peeling, ensure the softness and smoothness of the lips, and improve the texture and usage experience of the lipstick. β-sitosterol can improve the uniformity of the lipstick, and has good ductility during the application process, making the lipstick application smoother and more natural.

[0029] In a second aspect, the present application provides a method for preparing a moisturizing and silky lipstick, which adopts the following technical solution: A method for preparing a moisturizing and silky lipstick comprises the following steps: S1, pentaerythritol tetraisostearate, ethylhexyl palmitate, bis-diglyceryl polyacyl adipate-2, caprylic / capric triglyceride, octyldodecanol, and a colorant are mixed and stirred uniformly at 80-85° C. to obtain a primary mixture; S2. Weigh ozokerite, polyethylene wax, beeswax, and candelilla wax, heat them to 80-85° C. and heat until they are all hot-melted to obtain liquid wax. Add the liquid wax to the primary mixture and stir evenly. Then, add avocado oil, macadamia nut seed oil, and phytosterols, mix well, and obtain a mixture. S3. Add preservatives and antioxidants to the mixture, mix and stir evenly, inject into a mold, cool and solidify, and obtain a finished lipstick.

[0030] By adopting the above technical solution, the prepared lipstick has the advantages of moisturizing, nourishing, good color saturation and durability, and good waterproofness.

[0031] In summary, this application has the following beneficial effects: 1. Pentaerythritol tetraisostearate can evenly disperse colorants and improve the color saturation of lipstick; combined with ethylhexyl palmitate, bis-diglyceryl polyacyl adipate-2 and caprylic triglyceride as humectants in lipstick, it can improve the moisturizing and wetting effect of lipstick; combined with the moisturizing effect of avocado tree butter and macadamia seed oil on the lips, the palmitic acid, stearic acid and other substances contained in them can moisturize the lips and increase skin elasticity, thereby further improving the moisturizing effect through moisturizing effect, making it less likely to cause lip chapping after long-term use of lipstick, improving the durability of lipstick color while having a long-term moisturizing and hydrating effect.

[0032] 2. Titanium dioxide, hydroxyapatite particles, and polyethylene glycol solution are combined to utilize the barrier effect of hydroxyapatite particles to minimize direct contact of titanium dioxide with the lip skin, which may cause sensitivity problems for users. The polyethylene glycol solution adsorbed on the surface of hydroxyapatite particles improves the dispersion uniformity and stability of CI 77891 in the lipstick, and can also improve the color durability of the lipstick on the lip surface. Hydroxyapatite has a certain glossiness, which can increase the glossiness and fullness of the colorant. At the same time, the connection between hydroxyapatite particles, octyldodecanol, and polyethylene glycol can further improve the fineness and ductility of the lipstick.

[0033] 3. Ozokerite can increase the hardness of lipstick, polyethylene wax can thicken lipstick, making it less likely to break or break during use, beeswax can increase the soft texture of lipstick, making it easier to apply to the lips, and candelilla wax can stabilize lipstick and improve its texture.

Forty women aged 25-40 were divided into four groups, each with 10 participants, and each group was assigned to apply the lipstick samples prepared in Examples 1-4. The same amount of lipstick sample was applied. Ten minutes after application, the lips were rinsed with water for 1 minute at a flow rate of 100 mL / min. After the rinse, the lipstick retention was observed and scored according to the following criteria: no color change (10 points) → color disappearance (0 points).

[0059] 4. Sensitivity testing Lipsticks were prepared using the methods of Examples 1-5, and 50 women with sensitive skin aged 25-40 were selected and divided into 5 groups, each with 10 people, to try the lipstick samples prepared in Examples 1-5. After 10 days of application, the sensitivity was observed and divided into no sensitivity (abbreviated as none), mild sensitivity (abbreviated as mild), severe sensitivity (abbreviated as severe), and severe sensitivity (abbreviated as severe), and the data were recorded.

[0060] Table 1 Performance Test Table (“ / ” in the table indicates that the corresponding embodiment or comparative example was not tested for the item, so there is no data) In combination with Example 1 and Table 1, it can be seen that after using the lipstick prepared in the present application, the average roughness of the lips and the average depth of the lip lines of the user become lower after 20 days, indicating that the lipstick has good moisturizing and hydrating effects, and the area of the imprint after application is small, indicating that the color saturation and durability are good, and it also has the advantage of a certain waterproof effect.

[0061] Combining Example 1 and Examples 2-4 with Table 1, it can be seen that the treated colorant and candelilla wax can further improve the moisturizing effect of the lipstick, ensure the saturation and durability of the color, and ensure that the lipstick has good waterproof and anti-allergic effects.

[0062] A combination of Examples 2 and 5-8, along with Table 1, shows that no hydroxyapatite particles were added during the preparation of the CI 77891 carrier material in Example 5. Compared to Example 2, the initial and 20d differences in roughness and depth in Example 5 were smaller than those in Example 2, resulting in a rating lower than that of Example 2, indicating slight sensitivity. This indicates that the addition of hydroxyapatite particles can further prevent direct contact between CI 77891 and the lip skin, thereby controlling the occurrence of sensitivity. Furthermore, hydroxyapatite has a certain moisturizing effect, which can improve the moisturizing properties of the lipstick while also enhancing the gloss saturation and durability of the lipstick.

[0063] During the preparation of CI 15850 loading material in Example 6, no citric acid fatty acid glyceride was added. Compared with Example 2, the initial and 20d differences in roughness and depth in Example 6 were smaller than those in Example 2, resulting in a lower rating than Example 2. This indicates that the addition of citric acid fatty acid glyceride can further improve the dispersion uniformity of CI 15850 in the lipstick, thereby ensuring the color saturation and durability of the lipstick color. In addition, the presence of hydrophilic groups in citric acid fatty acid glyceride can further enhance the moisturizing effect of the lipstick.

[0064] During the preparation of CI 15850, the loading material for Example 7, no acetyl glucosamine solution was added. Compared to Example 2, the initial and 20d differences in roughness and depth for Example 7 were smaller than those for Example 2, resulting in a lower rating than Example 2. This indicates that acetyl glucosamine itself has a good moisturizing effect, can improve the moisturizing effect of lipstick and alleviate lip lines. In addition, the amino groups in acetyl glucosamine can further connect with substances containing hydroxyl groups, carboxyl groups, etc. in the lipstick, further improving the color saturation and durability of the lipstick.

[0065] During the preparation of the modified candelilla wax in Example 8, no coconut wax was added. Compared with Example 2, the initial and 20d differences in roughness and depth in Example 8 were smaller than those in Example 2, and the rating was lower than that in Example 2, indicating that coconut wax can adjust the hardness of candelilla wax and improve the moisturizing and flexibility of the lipstick.

[0066] From Example 1 and Comparative Examples 1-2 and Table 1, it can be seen that no avocado oil and macadamia seed oil were added to the raw materials of Comparative Example 1. Compared with Example 1, the initial and 20d differences in roughness and depth of Comparative Example 1 were smaller than those of Example 1, and the rating was lower than that of Example 1. This indicates that the combination of avocado oil and macadamia seed oil can further improve the moisturizing effect of the lipstick, thereby alleviating the problems of dry lines and cracks on the lips.

[0067] In Comparative Example 2, no octyldodecanol and phytosterols were added to the raw materials. Compared with Example 1, the initial and 20d differences in roughness and depth of Comparative Example 2 were smaller than those of Example 1, and the rating was lower than that of Example 1. This indicates that the combination of octyldodecanol and phytosterols can further enhance the moisturizing properties of the lipstick, thereby alleviating dry lines and cracks on the lips.

[0068] 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.
