[0031]

[0032] Table 1 Formulation table

[0033] The high-flow high-hiding power cosmetic powder is prepared by the following steps:

[0034] (1) Preparation of mixed solution: mix water, glycerin, antioxidant, preservative in mass percentage, and prepare the mixed solution;

[0035] (2) Preparation of A mixed powder: mix the various types of hydrophobic silane-modified silica according to the ratio with the mixed solution prepared in the corresponding example in a high-speed stirring powder homogenizer, and prepare the A mixed powder;

[0036] (3) Preparation of B mixed powder: add fluorine phlogopite, various types of colorants to the high-speed stirring powder homogenizer according to the mass percentage, and mix thoroughly to prepare the B mixed powder;

[0037] (4) Preparation of finished product: mix the A mixed powder and the B mixed powder prepared in the corresponding example, and prepare the cosmetic powder.

[0038] The various types of cosmetic powders prepared in the above examples 1-5 are subjected to performance testing by the following test examples:

[0039] Test example

[0040] I. In-bottle flowability observation method

[0041] The samples of the above examples 1-5 are placed in a small sample bottle with a diameter of 3 cm and a height of 7 cm, and after sealing, the following two in-bottle flowability observations are performed, and the corresponding observation results are as follows:

[0042] ① Random swing observation:

[0043] Swing the bottle back and forth with an amplitude of 2.5 cm / s, and observe the state of the cosmetic powder in the bottle. The cosmetic powder of each example has good single-wave overflow effect, and the wave-shaped cosmetic powder does not appear to be hanging on the wall under the condition of natural falling back into the bottle, and the falling speed is fast and the falling surface is flat.

[0044] ② In-bottle slow rolling observation:

[0045] Place the bottles containing the cosmetic powders of Examples 1-5 horizontally and shake each bottle until the cosmetic powder is approximately level (due to its high fluidity, only 1-3 shakes are needed). Then, roll the bottles at a speed of 0.5-1 cm / s towards the side away from your line of sight. Observe the rolling surface between the highest point of the flowing powder pile on the side of the bottle wall closest to your line of sight and the surface formation of each example. The rolling surfaces of each example exhibit the following visual effects:

[0046] In Examples 1, 4, and 5, the central area of ​​the rolling surface was flat, and no obvious cracks due to poor flowability were found. In areas where the flow rate differed significantly from the central area and adhered to the bottle bottom wall, only a few minor flow cracks were observed after multiple tests. In Examples 2 and 3, the central area of ​​the rolling surface was generally flat, and minor flow cracks were observed a few times after multiple tests. In areas where the flow rate differed significantly from the central area and adhered to the bottle bottom wall, minor flow cracks were observed. All cosmetic powders in Examples 1-5 exhibited no residue sticking to the bottle wall. When a small amount of cosmetic powder was located between the bottle wall and the powder's flowing surface, a clear layered rolling phenomenon was observed, without any residue sticking to the bottle wall during rolling.

[0047] II. Angle of Repose Measurement Method

[0048] The flowability of the cosmetic powders from Examples 1-5 was measured using a BOS-1007 angle of repose measuring instrument. Using samples in their natural state as a baseline, the angle of repose of the cosmetic powder was determined according to sections 4.5.4-4.5.5 of GB / T 16913-2008, 4.5 Determination of Angle of Repose (Impulse Limiting Bottom Surface Method). Specifically, sufficient cosmetic powder to overflow the tray was poured from the funnel opening onto a horizontal tray, and the acute angle between the slope of the accumulated powder and the bottom horizontal plane was measured; this angle corresponds to the angle of repose of the target cosmetic powder. Six measurements were performed on each of the cosmetic powders from Examples 1-5, and the data obtained are as follows:

[0049]

[0050] The angle of repose A was measured six times for each of the above samples. i And calculate the arithmetic mean angle of repose A. cp The angle of repose A of each set of embodiments was measured. i - Angle of Repose A cp The absolute value of the above absolute value is the deviation value, and none of them are greater than three times the root mean square deviation σ of the corresponding embodiment, that is, the average angle of repose A of the corresponding embodiment. cp The results are from the measurement.

[0051] Based on the above tests, the products of Examples 1-3 were found to have good flowability, while the products of Examples 4-5 had weaker flowability than those of Examples 1-3, but still had good flowability. At the same time, the numerical deviations of the flowability test results among the above samples were small in multiple measurements, indicating that the flowability performance was relatively stable.

[0052] III. Local application test

[0053] Using the cosmetic powder from Examples 1-5 above, loaded with... Figure 2 In a spray bottle, the powder was sprayed onto the hand in a single, single-point application with a diameter of approximately 0.5 cm by bringing the nozzle close to the hand and squeezing the air bladder. Local application tests were conducted using fingers and a makeup ball as application tools. Starting from the spray point, each spray point was applied five times in one direction until the powder dispersed to form a relatively uniform thin layer of makeup. The visually corresponding length was measured using a ruler, and the values ​​are as follows:

[0054]

[0055] The application test data from Examples 1-5 show that the cosmetic powders from Examples 1-5 all exhibit good application and blending effects when applied with fingers. In particular, Example 3, which uses finer-particle raw materials to prepare the cosmetic powder, has a relatively better application and blending effect than the other examples. In contrast, Example 2, which uses larger-particle raw materials to prepare the cosmetic powder, has a relatively weaker application and blending effect than the other examples. However, overall, the performance of each example is similar.

[0056]

[0057] The application test data from Examples 1-5 show that the makeup powders from Examples 1-5, when applied using a makeup ball, all exhibit good application and blending effects. Furthermore, the application and blending effects of the makeup powders from each example are similar, although they are relatively inferior to those applied with fingers. This may be because the porous structure of the makeup ball absorbs some of the makeup powder particles, resulting in a relatively inferior application and blending effect compared to finger application. However, at the same time, the application effects of the makeup powders from each example also show a high degree of consistency. With more proficient application skills, users can more accurately apply different types of makeup powders for more precise makeup application.

[0058] IV. Color difference test for local application

[0059] Based on the results of the above smearing test, the color difference of the cosmetic ball smearing area was measured using an X-Rite MetaVue Model VS3200 colorimeter. The measurement sites were the starting point, middle point, and end point of the smearing area. The measured values were compared to obtain the corresponding test data (the first two digits after the decimal point were taken, rounded off). The details are as follows:

[0060]

[0061] After measuring, it was observed that the color of the cosmetic powders of Examples 1-5 was uniform between the starting point, middle point, and end point of the makeup area. The total color difference values of Examples 1-5 were low, which proved that the products of Examples 1-5 had strong smearing uniformity and easy-to-use properties. In particular, the color difference data of Example 1 showed that the difference between the starting point, middle point, and end point was extremely small and could be ignored, indicating strong color consistency and excellent easy-to-use properties for consumers.

[0062] Five, range smearing test and consistency test

[0063] Based on the formulation component proportions of Examples 1-5, three groups of cosmetic powders were prepared. The cosmetic powders of Examples 1-5 were sprayed onto the surface of paper three times, and then the entire paper was smearing with a cosmetic ball until the color was uniform, forming a thin layer of makeup area. The color difference of the central region of the thin layer of makeup area was measured using an X-Rite MetaVue Model VS3200 colorimeter and compared between groups. The color of the paper without spraying was also measured and compared to obtain the corresponding test data. The details are as follows:

[0064]

[0065] When the total color difference △E of the same group of products was measured to be between 0 and 1, the color difference was extremely small and almost imperceptible to the naked eye. The cosmetic powders prepared by mass production of the above formulations had strong consistency. At the same time, each group of products had strong hiding power and could fully mask the basic color of the paper after smearing onto the paper, with high hiding power.

[0066] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application and do not limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
