Description

Technical Field

[0001] The present invention relates to the field of cosmetics, and more specifically, to a filling type eyebrow pencil and a manufacturing method thereof. Background Art

[0002] The process used by conventional eyebrow pencil products on the market is basically to extrude and mold by applying pressure, and then recrystallize at a high temperature of 55°C to increase the hardness of the product. The disadvantages of this process are very obvious. A layer of white wax will precipitate on the outside of the pen core, which looks very unsightly.

[0003] In addition, some eyebrow pencils adopt the filling process, but mica is generally used as a filler in the filling process. For example, CN115245473A discloses a color powder-wrapped eyebrow pencil and a preparation method thereof, and the filler used is synthetic fluorphlogopite, mica and silica in a mass ratio of 5:2-3:1-1.6. Mica, as a natural mineral, may contain some heavy metals, such as lead and mercury. Attention should be paid to the source of the product to ensure its safety. At the same time, excessive use can easily cause discomfort.

[0004] Therefore, there is an urgent need to develop a new type of filling eyebrow pencil product in this field to increase the beauty and safety of the eyebrow pencil. Summary of the invention

[0005] The purpose of the present application is to provide a fillable eyebrow pencil and a method for making the same, which can not only solve the uncontrollable risks caused by the mica contained in the formula of the eyebrow pencil, but also solve the unsightly appearance caused by the extrusion process.

[0006] In the first aspect, the present application provides a refillable eyebrow pencil, which adopts the following technical solution: A filling type eyebrow pencil comprises the following components in percentage by mass: 35-47% of a viscosity controller, 16-21% of an emollient, 6-7% of a filler, 29-37% of a colorant, 0.2-0.5% of an antioxidant and 0.6-1.0% of a preservative; wherein the filler consists of zinc stearate and zinc palmitate.

[0007] Optionally, the mass ratio of the zinc stearate to the zinc palmitate is 1:1.

[0008] By adopting the above technical solution and using zinc stearate and zinc palmitate in a specific ratio to cooperate with each other, 29-37% of the colorant in the eyebrow pencil is uniformly dissolved or dispersed in the solvent, which can significantly improve the compatibility of the colorant in the formula. On the one hand, the agglomeration and stratification problems of the obtained product are reduced, and on the other hand, the coloring effect of the eyebrow pencil can be better.

[0009] Optionally, the viscosity control agent is selected from the group consisting of hydrogenated soybean oil, hydrogenated vegetable oil, sumac peel wax, carnauba wax, microcrystalline wax and hydrogenated castor oil.

[0010] Optionally, the mass ratio of the hydrogenated wild soybean oil, hydrogenated vegetable oil, sumac peel wax, carnauba wax, microcrystalline wax and hydrogenated castor oil is 22-26:3-5:4-6:2-4:3-4:1-2.

[0011] By adopting the above technical solution and using a specific proportion of viscosity control agents in coordination, the uniform dissolution or dispersion of the colorant in the solvent can be further promoted, so that each component can be fully dissolved, making the eyebrow pencil more resilient.

[0012] Optionally, the emollient is selected from the group consisting of hydrogenated coconut glycerides, soy lecithin, caprylic / capric glycerides, argania spinosa kernel oil and coconut oil.

[0013] Optionally, the mass ratio of the hydrogenated coconut glycerides, soybean lecithin, caprylic / capric glycerides, argania spinosa kernel oil and coconut oil is 13-14:0.1-1:1-2:1-2:1-2.

[0014] By adopting the above technical solution, a specific proportion of emollient can make the eyebrow pencil feel more comfortable to apply. Using too much or an inappropriate ratio with the viscosity control agent will cause a large amount of the paste to adhere to the skin, while using too little will cause the formula to be hard and brittle, easily break during storage and transportation, and difficult to color when applying makeup.

[0015] Optionally, the colorant is selected from the group consisting of CI 77499, CI 77492, CI 77491 and CI 77891.

[0016] Optionally, the mass ratio of CI 77499, CI 77492, CI 77491 and CI 77891 is 8-11:17-20:2-3:2-3.

[0017] By adopting the above technical solution and using a specific proportion of CI 77499, CI 77492, CI 77491 and CI77891 to cooperate with each other, it is beneficial to improve the dispersibility between the colorant and the other components and improve the coloring effect of the eyebrow pencil.

[0018] In a second aspect, the present application provides a method for manufacturing a filling type eyebrow pencil, using the following technical solution: S1: Add viscosity controller and emollient into the oil phase pot, stir and heat at 88-98℃ until the material is completely dissolved and transparent; S2: Add antioxidant and preservative into the oil phase pot and mix well; S3: Add filler and colorant and mix evenly, cool to 40-50°C, grind 3-4 times until uniform and free of particles, and obtain a semi-finished product; S4: heating the semi-finished product to 85-90° C., stirring until completely dissolved, and injecting into a 1.0 mm mold using a filling device for solidification; S5: eject the pencil core from the filling mold, and put the pencil core into the packaging material to obtain a filling type eyebrow pencil.

[0019] By adopting the above technical solution, the eyebrow pencil is prepared by the filling process, which can not only achieve product performance equivalent to or better than the extrusion process, but also solve the unsightly problem caused by the extrusion process. However, when the colorant content is greater than 40% and the viscosity control agent is less than 30%, the filling process cannot produce an ultra-thin eyebrow pencil of 1.0 mm.

[0020] In a third aspect, the present application provides an application, which adopts the following technical solution: application of a composition comprising 6-7% of zinc stearate and zinc palmitate in the preparation of a refillable eyebrow pencil.

[0021] By adopting the above technical solution, the filler combination enables the eyebrow pencil to have a better coloring effect in the application of preparing a filled eyebrow pencil, and the prepared eyebrow pencil has higher toughness and safe ingredients.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. After forming, it has good toughness, can produce a pen core with a diameter of 1.0mm and makes the pen core not easy to break; 2. Hot filling process, no white wax will be precipitated on the outside of the pen core, which is more beautiful; 3. It has a more comfortable application feeling and better coloring effect.
