Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a 3D baking powder and a preparation method thereof. Background Art

[0002] In the late 1980s, cosmetic makeup technology slowly entered the Chinese market. After 20-30 years of continuous development, a new product name appeared in the list of makeup powder products: "baked powder". The appearance of baked powder was relatively simple at the beginning, mainly with circular convex patterns. The effects of using it were that the texture was hard when applied and the pearlescent effect was not shiny enough. However, in the past 10 years or so, China has continuously innovated the technology of baked powder products, with great innovations in appearance, texture and three-dimensional effects, and great breakthroughs in application texture. However, there are still many areas that require greater technical breakthroughs, such as not being light, delicate, moisturizing or shiny enough.

[0003] CN103239367A discloses a baking powder, which contains silicon-treated talc, nylon powder, magnesium aluminum silicate, Sanxian gum, mica powder, silica, polydimethylsiloxane, triglyceride, colorant, ethylhexylglycerol, sodium benzoate and monoglyceride. During the preparation, silicon-treated talc, nylon powder, magnesium aluminum silicate, Sanxian gum, mica powder, silica, polydimethylsiloxane, triglyceride, colorant, ethylhexylglycerol, sodium benzoate and monoglyceride are weighed respectively according to the weight ratio. Sodium benzoate and monoglyceride are then mixed with silicon-treated talc, nylon powder, magnesium aluminum silicate, Sanxian glue, mica powder, silica, polydimethylsiloxane, triglyceride, and colorant. The mixture is then pulverized and filtered in a high-speed airflow mill. Ethylhexylglycerol, sodium benzoate, and monoglyceride are then added. The mixture is then pressed into a plastic box or aluminum foil, then baked in an oven at 40-50°C for 2-10 hours. The finished product is then packaged. The addition of a larger amount of pearlescent and mica results in a more vibrant color, a more vibrant and three-dimensional pearlescent effect, and a closer-to-skin finish. The product surpasses conventional products in terms of appearance, structure, color saturation, gloss, powder cohesion, and shatter and shock resistance.

[0004] The baking powder disclosed in CN102048656A contains: 1-4% magnesium stearate; 1-3% polyethylene wax powder; 4-7% magnesium aluminum silicate; 4-6% titanium dioxide; 1-3% silicon dioxide; 1-2% corn starch; 20-50% pearlescent powder; 0.5-2% phenylsiloxane; 0.5-1% polyvinyl alcohol; and appropriate amounts of antioxidants, emulsifiers, and deionized water. During preparation, the raw materials are mixed, pressed into blocks, and baked at 70-90 degrees Celsius for 3.5-4.5 hours. After the oven is closed, the blocks are allowed to cool naturally in the oven for half an hour to one hour.

[0005] CN115154335A discloses a method for preparing baking powder, which comprises mixing a main powder material with an additive to obtain a mixed dispersed slurry; drying the mixed dispersed slurry using supercritical CO2 under first environmental conditions, including a first temperature of 25-50°C and a first pressure of 5-50 MPa; and then calcining the mixture to obtain the baking powder. By utilizing the characteristics of supercritical CO2 fluid, which has a larger diffusion coefficient than liquids, good permeability, and low mass transfer resistance, the baking powder is dried using supercritical CO2, allowing the CO2 to enter the material and exchange or transfer gently and rapidly with the baking powder particles. The material itself does not shrink or fragment, thereby largely maintaining the structure and state of the baked material, effectively preventing the agglomeration and coalescence of the powder particles, and the collapse of the capillaries, thereby avoiding a reduction in the specific surface area and pore volume of the baking powder.

[0006] Existing baking powder mainly improves the performance of baking powder by improving the formula, or uses relatively complex processes to obtain high-quality baking powder. Summary of the Invention

[0007] The present invention aims to overcome at least one shortcoming of the prior art and provide a 3D baking powder and a preparation method thereof.

[0037] The moisturizer and preservative used in the present invention are mixed with a synergist to form a grease complex, which can make the product more comfortable, moisturizing, smooth and bright.

[0038] The emulsifier and moisturizer used in the present invention are mixed and then combined with water molecules to form an emulsion effect. The oil complex in the product is fully mixed with the powder particles, allowing each powder particle to absorb more evenly and saturatedly, thereby improving the moisturizing and emollient properties of the product.

[0039] The thickener used in the present invention combines with water molecules to form a thickening effect, which plays a major role in the fineness of the 3D shape and the structural framework. In terms of anti-fall, it is not easily damaged by external forces, which greatly improves the stability of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention uses a three-stage variable frequency baking temperature to allow each powder particle in the formula to repeatedly absorb the oil and fat complex object components in the formula during the low and medium temperature baking in the first and second stages, so that each powder particle can more evenly absorb the oil and fat complex object in the formula, reducing the volatilization of the oil and fat complex object caused by directly baking it under high temperature conditions; under the high temperature conditions of the third stage, the medium responsible for carrying the oil and fat complex object into the powder particles is accelerated, and then reverse osmosis overflows from the inside of the powder particles and evaporates from the surface of the powder block, thereby making the product lighter, more translucent, more delicate, more fitting and moisturizing, and more crystal clear.

[0046] The moisturizer and preservative used in the present invention are mixed and compounded with a synergist to form an oil-fat complex, which can make the product more superior in terms of fit, moisturizing, slippery feeling and brightness.

[0047] The emulsifier and moisturizer used in the present invention are mixed and then combined with water molecules to form an emulsion effect. The oil complex in the product is fully mixed with the powder particles, so that each powder particle absorbs more evenly and saturatedly, thereby improving the moisturizing and emollient properties of the product to a higher level.

[0048] The thickener used in the present invention combines with water molecules to form a thickening effect, which plays a major role in the fineness of the 3D shape and the structural framework. In terms of anti-fall, it is not easily damaged by external forces, which greatly improves the stability of the product.

[0049] The following disclosure provides numerous different embodiments or examples for implementing various aspects of the present invention. A 3D baking powder was prepared according to the formula in Table 1. Caprylyl glycol was selected as the preservative; polysorbate 80, polyglyceryl-6 stearate, polyglyceryl-6 behenate, and hydrogenated lecithin were selected as the emulsifiers; gellan gum and xanthan gum were selected as the thickeners; cyclopentasiloxane and cyclohexasiloxane were selected as the synergist; silica was selected as the skin feel agent; and butylene glycol, cetearyl ethylhexanoate, and isopropyl myristate were selected as the moisturizers.

[0050] The specific preparation process includes the following steps:

[0051] Table 1

[0052]

[0053] 1) Add weighed pure water, butylene glycol, polysorbate 80, gellan gum, and xanthan gum into a container and dissolve them in a water bath at 80-90°C. Stir with a blender at 100 rpm for 5-10 minutes until the mixture is evenly dispersed into a translucent state. Maintain the temperature of the mixture at 70-80°C.

[0054] 2) Add cyclopentasiloxane cyclohexasiloxane, glyceryl-6 stearate, polyglyceryl-6 behenate, and hydrogenated lecithin to a container and begin to dissolve in a water bath at 80-90°C. Stir with a blender at 100 rpm for 5-10 minutes until the mixture is evenly dispersed into a translucent state. Maintain the temperature of the mixture at 70-80°C.

[0055] 3) Slowly pour the material in the container of step 2 into the container of step 1, and adjust the stirring speed of the emulsifier to 5000 r / min. After the material in the container of step 2 is poured into the container, stir at 5000 r / min for 3-5 minutes to obtain a semi-solid material;

[0056] 4) Add the raw silica into the powder mixer, then add the colorant, cetearyl ethylhexanoate, isopropyl myristate, and caprylyl glycol into the machine, start the machine and stir once until evenly dispersed before packaging;

[0057] 5) Slowly add the powder from step 4 to the semi-solid material from step 3, and stir with a mixer at 100 rpm for 3-5 minutes to obtain a semi-solid powder;

[0058] 6) Pour the powder obtained in step 5 into a mold, set the freezer temperature and time, freeze at -20°C for 20 minutes, demold and package to obtain the semi-finished product;

[0059] 7) Place the semi-finished product into the baking machine and set the oven temperature and time to create the 3D baked powder product. The baking process is as follows: first stage at 25-28°C for 6 hours; second stage at 35-38°C for 6 hours; third stage at 48-52°C for 8 hours.

[0060] The 3D baking powder product prepared by formula 1 is as follows Figure 1 Then, the evaluation results of 10 professional cosmetics evaluators are summarized in Table 2 below:

[0061] Table 2

[0062]

[0063] In summary, the formula of the present invention has no obvious difference in 3D stereoscopic effect compared with the currently sold products, but has obvious advantages in terms of lightness, transparency, delicate texture, fit and moisturizing, and crystal clear effect.

[0064] Effects of different baking procedures on baking powder properties

[0065] The compositions of Examples 1 to 9 are the same as those of Formula 1, except that different baking procedures were used in the preparation process. The specific procedures are shown in Table 3, and the experimental results are shown in Table 4 and Figures 2 to 5 .

[0066] Table 3 Baking procedures for different examples

[0067]

[0068] Table 4 Quality evaluation of baking powder obtained from different examples

[0069]

[0070] As shown in Table 4, compared to currently available products, the three-stage variable frequency baking process of Examples 5-8 produces products with a three-dimensional and refined appearance, a lighter, more translucent finish, a more delicate texture, a smoother, moisturizing, and crystal-clear appearance. The three-stage variable frequency baking process of Example 5 has a shorter baking time, resulting in a slightly drier texture. Its quality is slightly inferior to that of Examples 6-8, but significantly better than that of Examples 1-4. The relatively high baking temperature of Example 9 results in reduced performance of the baking powder.

[0071] The above is a further detailed description of the present invention and should not be considered as a limitation on the specific implementation of the present invention. For those skilled in the art, simple deductions or substitutions that do not depart from the concept of the present invention are within the scope of protection of the present invention.
