[0002] Excellent base makeup is the real foundation of perfect makeup. Primer is a kind of base makeup product. It can be used before applying makeup to modify the skin and create a perfect base makeup.

[0003] At present, common cosmetics all have their own characteristics, such as good moisturizing effect, nourishing effect, sun protection and isolation effect, etc. However, as the functions of pre-makeup products gradually become richer, consumers will also prefer multi-effect products. This can not only solve the problem of multiple cosmetics applied multiple times in pursuit of different effects, causing damage to the skin surface structure and skin discomfort.

[0004] Therefore, consumers expect a primer with multiple functions, including: 1) Suitability for skin type: Depending on their own skin type, consumers will have corresponding requirements for the product's moisturizing / oil-control ability; 2) Modifying / concealing ability: that is, the product's ability to brighten, modify pores and fine lines; 3) Skin protection ability: that is, to isolate the skin from damage by makeup; 4) Natural fit: to facilitate subsequent makeup application, make the base makeup fit the skin better, and have the ability to last; 5) Skin nourishment: to provide nutrition to the skin and the ability to nourish the skin.

[0005] In addition, the traditional use of primer is to apply it on the face with hands or a powder puff, which not only causes waste but also easily causes the problem of uneven makeup application, thus failing to achieve the desired effect.

[0006] In view of this, it is necessary to improve the cosmetic products in the prior art to solve the above problems. Summary of the invention

[0007] The first object of the present invention is to disclose a multi-effect all-in-one makeup primer based on handheld electrostatic spray. By utilizing the nano-delivery function of electrostatic spray, a fine film is formed on the skin surface, which has the effect of moisturizing, making the makeup more natural and lasting, and the nanoparticles are more conducive to the absorption of nutrients.

[0008] To achieve the above-mentioned purpose, the present invention provides a multi-effect all-in-one primer based on handheld electrostatic spray, which is composed of a phase A component and a phase B component; wherein the phase A component is composed of substances in the following weight component ratio: 8-13 parts of a delivery substrate, 100 parts of a solvent, 4-6 parts of a moisturizer, 1-1.5 parts of an emulsifier, and 1-1.5 parts of a nutrient; and the phase B component is composed of substances in the following weight component ratio: 3-16 parts of a skin conditioner and 0.05-1 part of a preservative.

[0009] In some embodiments, the skin conditioning agent is composed of the following components in the following weight ratio: 4-6 parts of cyclopentasiloxane, 3-5 parts of polydimethylsiloxane, and 3-5 parts of polydimethylsiloxane / vinyl polydimethylsiloxane crosspolymer.

[0010] In some embodiments, the delivery substrate is polyvinylpyrrolidone (PVP), the solvent is deionized water, the humectant is glycerol, the emulsifier is polysorbate-20, and the nutrient is collagen.

[0011] In some embodiments, the preservative is methylparaben.

[0012] In some embodiments, the material is composed of the following components by weight: 1 part of a nutrient, 13 parts of a delivery base, 100 parts of a solvent, 4 parts of a moisturizer, 0.7 parts of an emulsifier, 4 parts of cyclopentasiloxane, 3 parts of polydimethylsiloxane, 5 parts of polydimethylsiloxane / vinyl polydimethylsiloxane crosspolymer, and 0.05 parts of methylparaben.

[0013] The second objective of the present invention is to disclose a method for preparing a multi-effect primer based on a handheld electrostatic spray, breaking the traditional method of applying primer and using a handheld electrostatic spray to deliver the primer to the skin.

[0014] To achieve the above object, the present invention provides a method for preparing a multi-effect primer based on a handheld electrostatic spray, comprising the following steps:

[0015] 1) Step 1: Dissolve the delivery substrate, solvent, moisturizer, emulsifier, and nutrient in proportion under stirring at 800-1200 rpm / min, and mix evenly to obtain a phase A component;

[0016] 2) Step 2: Dissolve the skin conditioning agent and preservative in proportion under stirring at 800-1200 rpm / min, and mix well to obtain a phase B component;

[0017] 3) Step 3: First, use a disperser homogenizer to disperse phase A at 5000-6000 rpm / min for 1-2 minutes, then add phase B while dispersing phase A and continue dispersing for 8-10 minutes to obtain a primer.

[0018] In some embodiments, the method further comprises the following step: preparing a primer film coating on the skin surface by using an electrostatic sprayer.

[0019] In some embodiments, the voltage of the electrostatic sprayer is 6-11 kV, and the flow rate is 0.3-0.8 ml / h.

[0020] Compared with the prior art, the invention has the following beneficial effects: the multi-effect all-in-one makeup primer based on handheld electrostatic spray and the preparation method thereof disclosed in the invention. By utilizing the nano-delivery function of electrostatic spray, a fine film is formed on the skin surface, which has the effect of moisturizing; the nano-spray can not only hide pores and fine lines, smooth the skin, but also be more delicate and smooth than the traditional hand-painting method; the makeup is more natural and has the ability to last. It can also make nutrients more evenly distributed on the face, which is more conducive to skin absorption. It can also isolate dust, makeup, and bacteria, and prevent dust and makeup from clogging pores and causing skin problems such as acne and closed pores.

[0021] The present invention breaks the traditional method of applying primer and adopts a handheld electrostatic spray to deliver the primer to the skin, which reduces the waste of primer. The nanoparticles are more likely to fill the pores and form a film, making the makeup look more delicate and smooth. In addition, the nanoparticles are more conducive to the absorption of nutrients. The primer of the present invention not only has the multifunctional function of modifying the skin but also focuses on skin care. It is a base makeup product and also a skin care product.

[0027] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0028] like Figure 1-5As shown, this embodiment provides a multi-effect primer based on handheld electrostatic spray, which is composed of a phase A component and a phase B component; wherein the phase A component is composed of substances in the following weight component ratio: 8-13 parts of a delivery substrate, 100 parts of a solvent, 4-6 parts of a moisturizer, 1-1.5 parts of an emulsifier, and 1-1.5 parts of a nutrient; the phase B component is composed of substances in the following weight component ratio: 3-16 parts of a skin conditioner, and 0.05-1 part of a preservative.

[0029] The skin conditioning agent is composed of the following components in weight ratio: 4-6 parts of cyclopentasiloxane, 3-5 parts of polydimethylsiloxane, and 3-5 parts of polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer.

[0030] The delivery substrate is polyvinylpyrrolidone (PVP), the solvent is deionized water, the moisturizer is glycerol, the emulsifier is polysorbate-20, and the nutrient is collagen.

[0031] The preservative is methylparaben.

[0032] The primer of this embodiment is preferably composed of the following components by weight: 1 part of nutrient, 13 parts of delivery base, 100 parts of solvent, 4 parts of moisturizer, 0.7 parts of emulsifier, 4 parts of cyclopentasiloxane, 3 parts of polydimethylsiloxane, 5 parts of polydimethylsiloxane / vinyl polydimethylsiloxane crosspolymer, and 0.05 parts of methylparaben.

[0033] The delivery substrate of this embodiment is preferably polyvinylpyrrolidone (PVP). PVP can form a flexible and transparent film after the water evaporates, and the hygroscopicity of PVP enables it to absorb and retain moisture in the air, helping the skin to stay hydrated. Since PVP can form a thin protective film on the skin surface, this film can not only prevent water loss, but also enhance the smoothness and softness of the skin.

[0034] PVP also has dispersing and stabilizing properties, which can ensure that the ingredients of the primer are evenly distributed. PVP can also accelerate the penetration of cosmetic ingredients, prolong the retention time of ingredients, and enable active ingredients to act on the skin more effectively. In addition, PVP has no obvious irritation to the skin and mucous membranes, and will not cause allergic reactions. It is suitable for people with sensitive skin. PVP will not accumulate in the body, and its metabolites will not pose a threat to human health. PVP can also reduce greasiness and have a good softness and smoothness.

[0035] Therefore, polyvinylpyrrolidone (PVP) is preferred as the delivery matrix in the present invention.

[0036] In this embodiment, the primer film is prepared by an electrostatic sprayer and directly deposited on the skin to form a coating effect. The specific preparation method includes the following steps:

[0037] 1) Step 1: Dissolve the delivery substrate, solvent, moisturizer, emulsifier, and nutrient in proportion under stirring at 800-1200 rpm / min, and mix evenly to obtain a phase A component;

[0038] 2) Step 2: Dissolve the skin conditioning agent and preservative in proportion under stirring at 800-1200 rpm / min, and mix well to obtain a phase B component;

[0039] 3) Step 3: First, use a disperser homogenizer to disperse phase A at 5000-6000 rpm / min for 1-2 minutes, then add phase B while dispersing phase A and continue dispersing for 8-10 minutes to obtain the finished product.

[0040] The method also includes the following steps: preparing a primer film coating on the skin surface by using an electrostatic sprayer.

[0041] The voltage of the electrostatic sprayer is selected to be 6-11 kV, and the flow rate is selected to be 0.3-0.8 ml / h. In this embodiment, the preferred voltage is 11 kV and the flow rate is 0.5 ml / h.

[0042] In order to better illustrate the coating effect of the primer film formed in this embodiment, the comparative examples 1-4 of the present invention lack different components compared with the embodiment, specifically: Figure 1 As shown. Control Example 1 does not contain the B phase component, and the moisturizer glycerin and the emulsifier polysorbate-20 are also missing in the A phase; Control Example 2 does not contain the B phase component, and the emulsifier polysorbate-20 is missing in the A phase; Control Example 3 contains only one skin conditioning agent cyclopentasiloxane; Control Example 4 contains two skin conditioning agents cyclopentasiloxane and polydimethylsiloxane; and this embodiment contains three skin conditioning agents.

[0043] from Figure 3 It can be seen that compared with Control Example 1, Control Example 2 clearly shows that after adding glycerin (moisturizer), it will not turn white or dry out when sprayed on the skin, and the skin feels more evenly glossy.

[0044] Compared with Control Example 2, after adding cyclopentasiloxane (skin conditioner) to Control Example 3, the microscope picture of the primer liquid solution showed that the cyclopentasiloxane was encapsulated, and the encapsulated cyclopentasiloxane was also clearly seen in the spray particles, and the skin felt more natural after electrospraying.

[0045] Compared with Control Example 3, after adding polydimethylsiloxane (skin conditioner) to Control Example 4, more droplets are encapsulated in the primer liquid. Both the liquid solution and the spray microscope images show that polydimethylsiloxane is also encapsulated, and the skin feels more natural after spraying on the skin.

[0046] Compared with the control example 4, after adding the polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer (skin conditioning agent), the present embodiment also uniformly wraps the skin, greatly reduces the tightness after spraying the skin, and has the effect of hiding pores and fine lines and smoothing the skin. It can be seen that the addition of the three skin conditioning agents of the present invention can better maintain the comfort of the skin surface coating, and has the effect of smoothing the skin and moisturizing the skin.

[0047] This example also tests the moisturizing effect and makeup lasting effect of the primer film coating effect prepared by electrostatic spray. The makeup lasting effect referred to in the present invention refers to the duration of the cosmetics, that is, the time the cosmetics remain on the skin, which is also an important indicator for measuring the quality of cosmetics.

[0048] like Figure 4 As shown, spraying the primer of the present invention can effectively maintain the moisture of the skin for more than 8 hours, while if the primer is not sprayed, the moisturizing effect is greatly reduced.

[0049] like Figure 5 As shown in the figure, makeup (foundation liquid) was applied on the skin after spraying the primer and on the skin without spraying. After 6 hours of makeup application, the foundation liquid without the primer was wiped off very easily, while the foundation liquid after the primer was sprayed was hardly wiped off. This shows that the primer has the effect of making the base makeup more solid.

[0050] The makeup base of the present invention contains a skin conditioner, which can effectively ensure the moisturizing effect and the makeup lasting effect. The skin conditioner is composed of cyclopentasiloxane, polydimethylsiloxane, and polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer. Cyclopentasiloxane has excellent spreadability and permeability, can be quickly spread on the skin, and makes the skin feel soft and smooth. Due to its volatility, it will evaporate quickly after use and will not leave a greasy feeling on the skin. Polydimethylsiloxane can be used to provide skin moisturizing and softening effects, and can also form a protective film to prevent water loss. In addition, it also has certain antistatic and sunscreen effects. The polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer has better stability and elasticity, can be used as a thickener and stabilizer to improve the texture and stability of the makeup base, and can also provide a soft and smooth feeling on the skin.

[0051] Therefore, the makeup base of the present invention has the following characteristics due to the skin conditioning agent:

[0052] Lightweight and non-greasy: Due to the volatility of cyclopentasiloxane, primer and makeup will not leave a greasy feeling after application.

[0053] Moisturizing and Softening: Dimethicone and Dimethicone / Vinyl Dimethicone Crosspolymer work together on the skin to provide moisturizing and softening effects.

[0054] Texture Stabilization: Dimethicone / Vinyl Dimethicone Crosspolymer helps improve the texture and stability of products, making them more durable and easier to use.
