Description

TECHNICAL FIELD

[0001] The present application relates to the field of cosmetics, in particular to a safe setting powder and a preparation method thereof. BACKGROUND

[0002] Setting powder (also known as loose powder or face powder) is used to set makeup, that is, to fix the makeup in place. When only foundation is used, it will slide off with the secretion of oil, or the eye shadow and blush marks on the eye and cheek will destroy the makeup. Setting powder can solve this problem. Fine talc powder can absorb oil and keep the makeup in shape.

[0003] For example, Chinese patent application CN 107753408 A discloses a skin care loose powder formula. The raw materials in the formula are composed of calcium carbonate 1-5%, magnesium carbonate 1-5%, zinc oxide 2-4%, kaolin 5-13%, talc 15-20%, zinc stearate soap 8-10%, menthol 5-7%, pearl powder 8-10%, pearl powder 10-12%, corn flour 6-8%, rose powder 10-12%, and cocoa powder 5-8%, in order to achieve the effects of whitening and setting makeup.

[0004] For another example, Chinese patent application CN 115177541 A discloses a transparent invisible setting cream. The total amount of raw materials of the transparent invisible setting cream is 100%, the talc accounts for 30%, the powder finishing and matting component accounts for 15%, the oil base accounts for 13%, the adsorbent accounts for 6%, the fat absorbing component accounts for 12%, the adhesive accounts for 7%, the preservative accounts for 1%, the antioxidant accounts for 12%, and the perfume accounts for 4%. The talc is used to smoothly spread the other components on the skin. The powder finishing and matting component at least includes one or more of kaolin and titanium dioxide.

[0005] As can be seen, the existing setting powder all takes talc as the main component. However, the International Agency for Research on Cancer (IARC) research shows that excessive consumption or contact of talc by human body can cause cancer. As a product that cannot or must be used in the makeup process, setting powder increases the risk of cancer for users. Therefore, it is an urgent problem to provide a setting powder with good setting effect and high safety. SUMMARY

[0006] Therefore, the purpose of the present application is to provide a setting powder with good setting effect and high safety and a preparation method thereof.

[0007] To achieve the above object, the present application provides a safe setting powder, comprising the following raw materials in parts by mass: hollow glass microbeads 20-35 parts, kaolin 6-10 parts, calcium carbonate 3-10 parts, magnesium carbonate 12-15 parts, zinc oxide 12-15 parts, titanium white 10-15 parts, metallic soap 6-9 parts, perfume 0.1-0.3 parts, pigment 0.1-0.3 parts.

[0008] Preferably, the particle size of kaolin is 0.5-5 μm, the particle size of calcium carbonate is 20-200 nm, the particle size of magnesium carbonate is 1-20 μm, the particle size of zinc oxide is 20-50 nm, and the particle size of titanium white is 200-300 nm.

[0009] Preferably, the setting powder comprises the following raw materials in parts by mass: hollow glass microbeads 20-30 parts, kaolin 5-8 parts, calcium carbonate 5-8 parts, magnesium carbonate 13-14 parts, zinc oxide 13-14 parts, titanium white 12-13 parts, metallic soap 6-8 parts, perfume 0.1-0.2 parts, pigment 0.1-0.2 parts.

[0010] The hollow glass microbead, as an inorganic neutral material, is harmless to human body after long-term contact, has good flowability due to its smooth surface and spherical structure, and is easy to coat, thus having better lubricating effect than talc and being able to replace talc in the setting powder to reduce the risk of carcinogenesis to human body. Meanwhile, due to its spherical structure, the hollow glass microbead can diffuse light on its surface and has light extinction effect, thus being able to replace or reduce the use of kaolin, calcium carbonate and other light extinction materials in the setting powder. The hollow glass microbead, due to its small density, can increase the lightness of makeup and reduce the greasy feeling of makeup when added to the setting powder. In addition, as a spherical material of glass material, the hollow glass microbead, when replacing some materials in the setting powder, can block the effects of ultraviolet and infrared rays and has certain heat insulation effect, thus protecting the skin from being sunburned under strong sunlight.

[0011] Preferably, the hollow glass microbead has a true density of 0.65-1.6 g / cm 3 , and D90≤40 μm. More preferably, the hollow glass microbead has a particle size D10≥2 μm and a particle size D50 in the range of 15-30 μm, such as HS70, HM10 or HM30 from Zhengzhou Shenglaite Hollow Microbead Material Co., Ltd.

[0012] The hollow glass microbead has a floating rate of 100% in water, i.e., it is a hollow glass microbead after flotation, and the broken hollow glass microbead is removed to avoid scratching the human body due to the broken hollow glass microbead in the setting powder during use. The metallic soap is zinc stearate, magnesium stearate, calcium stearate or any combination thereof.

[0013] A preparation method of a setting powder, comprising the steps of:

[0014] Flotation of hollow glass microspheres: first, add raw hollow glass microspheres to deionized water and continuously stir for 20-30 min, and then stand for 20-30 min; then, filter and separate the upper layer of hollow glass microspheres floating in the deionized water, and dry to obtain the floated hollow glass microspheres;

[0015] Mixing: first, uniformly mix and grind other raw materials except the floated hollow glass microspheres, then add the floated hollow glass microspheres for uniform mixing, and then sieve and dry.

[0016] Therefore, the hollow glass microspheres used in the above setting powder have the following advantages:

[0017] I. Because of the positive spherical structure, the setting powder has better lubricity than the talc powder in the existing setting powder, so the setting powder not only reduces the risk of carcinogenesis to the human body and has high safety, but also has a long makeup holding effect, that is, even in a high-temperature or exercise state with excessive sweating, the pigmentation value retention rate is not less than 80%, which can ensure that the makeup is not removed for 8 hours and has high makeup holding stability.

[0018] II. The hollow structure of the hollow glass microspheres has good heat insulation effect, which can protect the skin from being sunburned under strong sunlight.

[0019] III. The hollow glass microspheres have small density, and when used in the setting powder, the lightness of the makeup can be increased, the greasy feeling of the makeup can be reduced, and the amount of kaolin, calcium carbonate, zinc oxide and other raw materials in the setting powder can be reduced; thus, the quality of the setting powder is ensured, and the price of the setting powder is reduced.

[0020] IV. The hollow glass microspheres have a matt effect, and can replace part of the matt substances such as kaolin and calcium carbonate, so that the makeup holding stability of the setting powder prepared therefrom changes little, but the thermal conductivity coefficient is relatively low, and the effect of preventing skin sunburn is relatively good.

[0021] V. The setting powder provided by the present application has a small required amount of application, and the particle size of the hollow glass is larger than that of talc powder (commonly used particle size ≤ 5 μm) and other substances, and the surface is smooth, which can weaken or prevent the pores from being blocked after long-term use (the diameter of human pores is about 20-50 μm). In addition, other large-particle-size fillers are not spherical, and do not have the smoothness of hollow glass microspheres, so the smoothness after application of products using other large-particle-size fillers is not enough. DETAILED DESCRIPTION

[0022] The technical solutions of the present application will be further described in detail through specific embodiments.

[0023] Examples 1-4 and Comparative Examples 1-3

[0025] Flotation of hollow glass microbeads: the original hollow glass microbeads are added into deionized water and stirred for about 25 min, and then left to stand for about 25 min; the hollow glass microbeads floating on the top of the deionized water are separated by filtration to remove the broken parts of the hollow glass microbeads, and then dried for use, to obtain the floated hollow glass microbeads;

[0026] Mixing: each raw material in the formula shown in Table 1 is sterilized, and then other raw materials except the hollow glass microbeads are mixed using a mixer, and the mixed raw materials are ground, and then the floated hollow glass microbeads and other powders are uniformly mixed in a V-type mixer, and finally the mixed materials are sieved through a 30 μm sieve and dried.

[0027] Table 1: Formula of setting powder

[0028]

[0029] The indexes of each raw material shown in Table 1 are as follows: the true density of hollow glass microbeads of type HS70 is 0.75-0.80 g / cm 3 , D90 is 15 μm, D50 is 10 μm, and D10 is 7 μm; the true density of type HM10 is 1.4-1.6 g / cm 3 , D90 is 10 μm, D50 is 5 μm, and D10 is 2 μm; the true density of type HM30 is 0.7-0.75 g / cm 3 , D90 is 30 μm, D50 is 20 μm, and D10 is 12 μm; the true density of type HS22 is 0.21-0.24 g / cm 3 , D90 is 70 μm, D50 is 30 μm, and D10 is 20 μm. The particle size of kaolin is 0.5-5 μm, the particle size of calcium carbonate is 20-200 nm, the particle size of magnesium carbonate is 1-20 μm, the particle size of zinc oxide is 20-50 nm, and the particle size of titanium white is 200-300 nm.

[0030] The properties of the setting powders provided by Examples 1-4 and Comparative Examples 1-3 are tested as follows, and the test results are shown in Table 2.

[0031] Oil absorption value test: according to GB / T3780.2-2007;

[0032] Thermal conductivity: the setting powder using tool is prepared into a cake with a diameter of 30 mm and a thickness of 2 mm, and a thermal conductivity tester is used to test the thermal conductivity at 50°C;

[0033] Makeup stability: the setting powder is applied on the arm, artificial sweat is sprayed every 30 minutes, and the skin pigmentation value is tested every 2 hours by a 3D skin imaging instrument, and the test is continued for 8 hours. The pigment retention rate is calculated after 8 hours to represent the makeup stability. The higher the pigment retention rate, the better the setting effect.

[0034] Table 2: Performance test results of setting powder

[0035] Sample Application feeling Oil absorption value / (ml / 100g) Pigmentation value retention rate / % Makeup feeling Thermal conductivity / W / (m·K) Example 1 Very smooth 131 87% Light 0.064 Example 2 Very smooth 138 82% Light 0.071 Example 3 Very smooth 144 88% Light 0.079 Example 4 Very smooth 112 85% Light 0.060 Comparative Example 1 Smooth 107 31% Heavy 0.125 Comparative Example 2 Dry, risk of scratching 151 43% Light, sandy feeling 0.086 Comparative Example 3 Grainy feeling 107 28% Light, grainy feeling 0.055

[0036] The main difference between Example 4 and Example 2 is that half of the amount of calcium carbonate in Example 2 is replaced with an equal volume of hollow glass beads, i.e. 4 parts by mass of calcium carbonate and 1 part by mass of hollow glass beads HM30 have equal volumes. As can be seen from Table 2, compared with Example 2, Example 4 reduces the amount of calcium carbonate, the oil absorption value of the setting powder is slightly reduced, but Example 4 has a lower thermal conductivity, i.e. better heat insulation effect, which can prevent skin sunburn; the pigment retention rates of Example 2 and Example 4 change little, both are above 80%, with high makeup stability.

[0037] The main difference between Comparative Example 1 and Example 1 is that the hollow glass beads in Example 1 are replaced with an equal volume of talc, i.e. 77 parts of talc and 20 parts of HS70 have equal masses. As can be seen from Example 1 and Comparative Example 1, using a smaller amount of hollow glass beads can achieve the effect of talc at an equal volume. The setting powder prepared by using hollow glass beads in Example 1 has a higher oil absorption value and better application touch, and the texture is more light; under the action of artificial sweat, the pigment retention rate of the setting powder provided by Example 1 remains above 80%, i.e. the makeup stability effect is better in the state of sweating such as exercise or high temperature.

[0038] The main difference between Comparative Example 2 and Example 3 is that the hollow glass beads in Comparative Example 3 are original glass beads without the aforementioned "flotation of hollow glass beads" treatment. As can be seen from Table 2, the hollow glass beads in Comparative Example 2 are not treated by flotation, which has the risk of scratching the skin; compared with Example 3, the oil absorption value of Comparative Example 2 changes little, the pigment retention rate decreases significantly, the makeup stability decreases obviously, and after applying the film, the makeup has a light texture, but also accompanied by a sandy feeling, the thermal conductivity increases, making the sunscreen and heat insulation effect of Comparative Example 2 worse.

[0039] The main difference between Comparative Example 3 and Example 1 is that Comparative Example 3 uses hollow glass microbeads HS22 instead of hollow glass microbeads HS70 in Example 1. Compared with Example 1, Comparative Example 3 has obvious particle feeling during application and during makeup, and the sunscreen and heat insulation performance is significantly improved. Although the thermal conductivity of Comparative Example 3 is lower, the oil absorption value is slightly reduced, the retention rate of pigmentation value is significantly decreased, and the makeup stability is obviously deteriorated.

[0040] Therefore, according to the performance test results of the examples and comparative examples shown in Table 2, it can be seen that the makeup fixing powder added with hollow glass microbeads has good makeup stability, especially in the case of sweating caused by exercise or high temperature, has better sunscreen and heat insulation effect, can effectively improve the protection of the skin, and at the same time, the makeup fixing powder with hollow glass microbeads has better application touch and makeup effect.

[0041] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application and not to limit it; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical solutions of the present application, they should be covered in the technical solution range of the present application.
