Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a natural brightening powder composition based on multi-particle-size powder compound, its preparation method, and its application. Background Technology

[0002] Pressed powder, a common makeup product, is favored by consumers for its portability and versatility. It is widely used for setting makeup, correcting skin tone, and concealing blemishes, effectively improving the longevity and appearance of makeup. Traditional pressed powder manufacturing methods primarily employ a pressing process, where powder raw materials (such as talc, mica, and titanium dioxide) are mixed with a binder and then mechanically pressed into shape.

[0003] To achieve a brightening effect, existing pressed powder products typically employ the following two technologies:

[0004] 1. Adding pearlescent pigments (such as mica titanium): This creates a brightening effect through strong mirror reflection. The disadvantages are that the makeup looks unnatural, has obvious artificial shimmer, easily accentuates skin pores and texture, and is prone to clumping and fading under the influence of oil and sweat, making it unsuitable for occasions where a natural makeup look is desired.

[0005] 2. Using high-concentration, single-particle-size white powder (such as titanium dioxide): This method primarily achieves whitening by scattering light. Its disadvantages include a tendency to result in a "fake white" and "heavy" makeup look, with a strong mask-like feel. Because the powder particles are of a single size, they cannot form a dense and smooth film on the skin's surface, leading to disordered light scattering and a harsh, unnatural brightening effect. Additionally, it results in a rough texture, poor adherence to the skin, and a tendency for powder to cake or flake.

[0006] Relevant patent documents retrieved: Chinese invention patent publication number CN120284749A discloses a method for preparing a setting and brightening powder compact. First, synthetic fluorophlogopite, silica, polymethylsilsesquioxane, boron nitride, bismuth oxychloride, zinc stearate, aluminum octenyl succinate starch, mica, alumina, hydrolyzed sodium hyaluronate, and pigment are mixed evenly in a homogenizer. Then, polydimethylsiloxane, octyldodecyl stearyl oxystearate, isoamyl laurate, diisostearyl malate, phenoxyethanol, and octyl glycol are mixed evenly and heated to 45±5℃. The mixture is then poured into the spray gun of the homogenizer, and mixed while spraying oil. After pulverizing, the mixture is further pulverized by air jet milling. The powder is then sieved and pressed into a mold plate to obtain a powder compact. Finally, it is placed in a packaging powder box to obtain the setting and brightening powder compact.

[0007] Another Chinese invention patent publication number CN120478182A discloses an oil-controlling and moisturizing powder compact with a multi-layer microporous structure and its preparation method, including powder, a first emulsion, and a second emulsion; the first emulsion is composed of a first moisturizer, hydrogenated lecithin, C12-20 acid PEG-8 ester, polysorbate-80, and water; the second emulsion is composed of a second moisturizer and water; the preparation method is as follows: the powder and the first emulsion are mixed and dried, and then mixed with the second emulsion to obtain a slurry; the slurry is first freeze-dried at -80℃ to -60℃, then freeze-dried at -40℃ to -5℃, and finally freeze-dried at -5℃ to 45℃ to obtain the powder compact.

[0008] However, the powder provided by the aforementioned invention patent still has poor brightening and concealing effects while maintaining makeup longevity. Summary of the Invention

[0063] The beneficial effects of this invention are as follows: 1. Compared with existing technologies that use a single particle size or a random combination of multiple particle sizes, this invention, which follows a three-stage powder system technology, has a better technical effect in terms of natural brightening.

[0064] According to experimental tests, this invention improves the brightening effect from the "fake white" and unnatural makeup look of existing technologies to a more natural, original glow; and improves the concealing effect from the uneven coverage of existing technologies to a more even and natural concealing makeup look.

[0065] 2. The natural brightening powder composition of the present invention overcomes the "glittery" feel of pearlescent pigments and the "fake white" feel of single powders. The light reflected by the optical plane is uniform and soft, resulting in a realistic and high-end makeup effect.

[0066] 3. This invention utilizes the dense packing of powders with multiple particle sizes to effectively scatter and blur the light reflection of blemishes such as pores and fine lines, achieving a soft-focus makeup effect like "skin smoothing". The product adheres well to the skin after application, effectively avoiding powderiness and heaviness.

[0067] Furthermore, based on the present invention: Based on the comparison of Examples 1-5 and Comparative Examples 1-13, the present invention employs the technical means of "a natural brightening powder composition based on multi-particle-size powder compound, comprising a base skeleton powder, a gap-filling powder, and a surface-smoothing powder, wherein the base skeleton powder comprises synthetic fluorophlogopite / magnesium myristate and mica / lauroyl lysine; the gap-filling powder comprises synthetic fluorophlogopite / triethoxyoctylsilane, mica, silica / triethoxyoctylsilane, magnesium myristate, and polyethylene; and the surface-smoothing powder comprises polymethyl silsesquioxane and boron nitride," achieving new technical effects: existing powders, while maintaining makeup longevity, still have unsatisfactory brightening and concealing effects. The combined technical effect is superior to the sum of the effects of each individual technical means. Attached Figure Description

The particle sizes of Examples 1 and 2 demonstrate better visual smoothness of the skin surface texture.

[0102] Detection Example 2 Thirty-six female volunteers, aged 20-40, with skin types including oily, dry, and normal skin, were selected and divided into 18 groups of two people each. The same makeup artist used the same makeup application method to conduct a full-face makeup test. The Lab values ​​and pore distribution of Examples 1-5 and Comparative Examples 1-13 were detected by a color difference instrument.

[0103] Verification of technical effectiveness and / or analysis of solutions to technical problems: The color difference Lab values ​​of Examples 1-5 and Comparative Examples 1-13 are shown in Table 5. It can be seen that the L values ​​of Examples 1-5 are significantly higher than those of Comparative Examples 1-13.

[0104] The full-face gloss effect images of Examples 1 and 2 are shown below. Figure 5 As shown; Comparative Example 1 and Comparative Example 2 show the full-face gloss effect. Figure 6 As shown; Comparative examples 3 and 4 show the full-face gloss effect. Figure 7 As shown; Comparative examples 5 and 6 show the full-face gloss effect. Figure 8 As shown, by Figures 5-8 The comparison shows that the powder compositions of Comparative Examples 1 to 6 have no obvious luster and no obvious brightening effect.
