Description

Technology Field

[0001] The present invention relates to a method for manufacturing cosmetics, and in particular to a method for manufacturing solid cosmetic powder. Background Technology

[0002] Cosmetic solid powders commonly found on the market today are primarily produced through a powder pressing process. Common ingredients used in this process include inorganic fillers, pearlescent pigments, metal soaps, oils, preservatives, and skin conditioners. The powder pressing process involves uniformly mixing and dispersing cosmetic solid powder components, such as inorganic fillers and pearlescent pigments, with oil components using mechanical stirring to obtain a mixture of cosmetic solid powders. This mixture is then filled into metal or plastic plates, and subsequently molded by pressing and filling with a metal mold to produce a cosmetic product made of solid powder. The powder pressing process primarily has two disadvantages: a. It places relatively high demands on the selection of materials used in the formulation, particularly regarding the proportion of low-density microspheres; otherwise, the resulting product may easily crack, break, or become loose. However, since low-density microspheres have a beneficial effect on soft focus, oil control, and longevity, reducing their usage would result in a failure to achieve the aforementioned makeup effects; b. There are also disadvantages in the process; environmental dust is relatively large, and significant powder loss causes the edges to become rough, which easily detaches due to vibrations during transportation.

[0003] To overcome the drawbacks of the powder pressing process, a wet powder filling process is generally used. However, the wet powder process often involves uniformly mixing and stirring organic solvents and cosmetic solid powders. After stirring, a powder slurry is formed and placed in a container. Then, the slurry is pumped into a syringe via a transfer pump, and the slurry is injected into a plastic box through the nozzle of the syringe and the filling port at the bottom of the container box. The container box is then sealed by pressing a block, volatile solvents are discharged by vacuum while pressing, and finally, the container box is placed in an environment between 40°C and 60°C and baked. However, the wet process also has drawbacks: a) commonly used solvents such as the isomers dodecane and isopropanol all carry a certain risk and can easily cause harm to the environment and the human body during the volatilization process; and b) it is difficult to guarantee that the resulting product does not contain trace amounts of these solvents.

[0004] Furthermore, both dry and wet pressing are subject to limitations in complex formulation processes; specifically, since the patterning of cosmetic solid powders is performed under pressure, and if the formulation process is relatively complex, it is difficult to achieve consistent pressure, the cosmetic solid powder may contain brittle or easily dispersed regions. To create a three-dimensional pattern on the surface of the cosmetic solid powder, a pattern must be engraved on a metal mold. To prevent the material from getting stuck in the engraved pattern of the metal mold, a flat insulating cloth must be placed between the metal mold and the material to be pressed. The flat insulating cloth must have a certain thickness, and elastic tension exists during the pressing process. If the pattern of the metal mold is too fine, the flat insulating cloth cannot form a clear pattern on the surface due to elastic tension and its own thickness. The problem to be solved

[0005] Accordingly, the present invention provides a method for manufacturing a cosmetic solid powder. means of solving the problem

[0006] To achieve the above objective, the present invention provides a method for manufacturing a solid cosmetic powder comprising the steps of: (1) obtaining material A by uniformly mixing powders, then uniformly mixing a natural polysaccharide with an appropriate amount of water, then adding a softening moisturizer and an emulsifier, and then uniformly mixing again to obtain material B, wherein the powder includes a flake filler, a spherical filler, and a pigment thereof; (2) obtaining a dispersion by uniformly mixing material A and material B, then adding a preservative; (3) heating the dispersion to a predetermined high temperature and then filling it into a mold; (4) freezing the dispersion to a predetermined low temperature and then releasing it to obtain a semi-finished product; and (5) drying the semi-finished product to obtain a finished product.

[0058] The cosmetic solid powder manufactured according to the above ingredients has no problem with molding but is relatively easily deformed, has a slippery feel, and is not easy to pick up with a brush, and the weight part of the soothing moisturizer is 20, which has already affected the sample, so the upper limit of the weight part of the soothing moisturizer should not exceed 20.

[0063]

[0064] Influence of mold temperature

[0065] The same components are filled into the same mold model, and the effects of cooling release and freezing release on the samples are observed. It can be seen that the effect of freezing release is better, and the surfaces of all samples are smooth and complete without damage. However, since the surfaces of the samples subjected to cooling release are damaged or samples are not formed, the preliminary conclusion is that the product cannot be cooled and released, proving that the effect of freezing release is clearly superior to that of cooling release (see Table 4-2).

[0066] [Table 4-2]

[0067] Influence of mold temperature

[0068]

[0069] Influence of drying conditions

[0070] The effect of drying conditions on samples was compared using three different drying methods: room temperature, a 55°C oven, and freeze-drying. Since the surface of the sample is damaged by cooling, a method of drying the sample in an oven at room temperature and 55°C and then releasing it was adopted. For freeze-drying, a freeze-release method was adopted, and samples were freeze-dried to compare the different drying conditions and obtain sample conditions.

[0071] More than 80% of samples dried at room temperature cannot be released. The main reason these samples cannot be released is that the samples adhere to the mold, damaging the sample surface. The apparent shrinkage rate of the samples is 60% or more, and the good yield of the samples is 0.

[0072] For samples dried at 55°C, more than 55% of the samples cannot be released. The main reason these samples cannot be released is that the samples adhere to the mold, damaging the sample surface. The proportion of samples with obvious shrinkage is more than 60%, and the sample yield is less than 40%.

[0073] For vacuum freeze-dried samples, the proportion of good samples with a perfect surface without obvious shrinkage is over 85%, and the proportion of good samples with only slightly rough surfaces is over 95%. For details, refer to Table 4-1 below.

[0074] [Table 4-3]

[0075] Examples of verified samples, samples with abnormal damage, samples with shrinkage, and samples with slightly rough surfaces are provided in FIGS. 1 to 4.

[0082] Relatively preferred specific embodiments of the present invention have been described in detail above. It should be understood that a person skilled in the art can make various modifications and changes according to the concept of the present invention without creative effort. Accordingly, all technical solutions that a person skilled in the art can obtain through logical analysis, reasoning, or limited experimentation based on prior art according to the concept of the present invention must be included within the scope of protection determined by the scope of protection of the claims.
