Description

Technical Field

[0001] The present invention relates to the field of cosmetics, and more particularly to a dip-in eyeliner and a preparation method thereof. Background Art

[0002] Liquid eyeliner is a product that uses special raw materials to evenly disperse colorants in water and is applied to the root of eyelashes through a brush to form a thin line with a beauty effect. It has the characteristics of smooth brush strokes, easy coloring, quick drying, and long-lasting and non-smudged. However, the liquid eyeliners currently on the market are limited by the particle permeability and air tightness requirements of the carrier packaging materials. The maximum amount of colorant added is generally 15-20%, and the amount of film-forming agent emulsion added is generally 20-40%. It has gradually failed to meet the consumer market group's demand for eye makeup lasting time and eye makeup color saturation. In addition, when the foundation is stained during makeup, the liquid discharge performance will decrease or even fail to discharge. After a long period of storage, the pen tip gradually dries due to the loss of airtightness and weightlessness, which affects the use of consumers.

[0003] In order to improve these problems, people have studied a special eyeliner product - eyeliner dip powder. It uses a dipping method to use a powder eyeliner. This type of eyeliner is usually made of fine powder particles suspended in a specific liquid medium. When using it, you need to attach the powder to an eyeliner brush or similar tool by dipping, and then draw the eyeliner effect along the root of the eyelashes. It has a richer and more lasting eyeliner effect. At the same time, it also has strong adhesion and can stay on the eyelid for a long time without removing makeup, meeting the need for long-lasting makeup. However, since the current commercially available eyeliner dip powder is used in an exposed state, it is still impossible to add a high proportion of film-forming emulsion, usually 20-40%, which greatly limits the room for improvement in the long-lasting makeup ability of the eyeliner dip powder. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides a dip-type eyeliner and a preparation method thereof.

[0005] In the first aspect, the present application provides a dip-type eyeliner pen, which adopts the following technical solution: A dip-in eyeliner comprises a dip-in powder and a liquid eyeliner. The raw materials used in the dip-in powder comprise the following components in percentage by mass: 20-55% of a colorant, 20-55% of a filler, 2-15% of a moisturizer, 0.5-1% of a preservative, 3-5% of a binder, and the balance is water; the raw materials used in the liquid eyeliner comprise the following components in percentage by mass: 30-80% of a film former, 5-15% of a moisturizer, 0.5-1% of a preservative, and the balance is water.

[0006] Through the above technical solution, the present application adopts the method of combining a dip-in powder with a liquid eyeliner pen, which can greatly increase the addition ratio of the colorant and the film-forming agent. The final dip-in eyeliner pen has both high color development and strong water resistance and smudge resistance, and the long-term makeup holding ability is significantly enhanced. In addition, the addition of fillers in the dip-in powder can make the dip-in eyeliner pen show a silky skin feel, and the sebum secreted on the skin surface can be absorbed by the filling powder under long-term makeup, further improving the anti-smudge performance of the dip-in eyeliner pen. In addition, since the liquid eyeliner pen of the present application does not need to add a colorant component, the particle permeability of the liquid eyeliner pen is significantly improved.

[0007] Preferably, the colorant is a natural colorant and / or an organic synthetic colorant. The particle sizes of the natural colorant and the organic synthetic colorant are both within the range of 250-800 nm. The natural colorant includes but is not limited to red iron oxide, yellow iron oxide, black iron oxide, titanium dioxide, bamboo charcoal black, etc. The organic synthetic colorant includes but is not limited to organic red synthetic colorant, organic blue synthetic colorant, etc.

[0008] Preferably, the filler is silicon powder and / or mica powder. The silicon powder is spherical silicon powder. The mica powder is flaky natural mica powder or synthetic mica powder. Among them, spherical silicon powder can make the dip-in powder smoother, and flaky mica powder can make the dip-in powder fit better. In the production process, one of the two can be selected and added according to actual needs, or the ratio of the two can be adjusted and added.

[0009] Preferably, the filler comprises porous particles and non-porous particles in a weight ratio of 1:(1-3), and the particle size range of the porous particles and the non-porous particles is 2-15 μm.

[0010] Through the above technical solution, the present application mixes and matches the porous particles and the non-porous particles in a certain proportion, so that the dip-in powder has a certain oil absorption capacity, absorbs the sebum secreted from the skin surface under long-term makeup, enhances the anti-smudge performance of the dip-in eyeliner, and maintains a silky skin feel. If the addition ratio of the non-porous particles is too low, the smoothness of the dip-in powder will be reduced. If the addition ratio of the non-porous particles is too high, the dip-in powder will be too smooth, thereby reducing the amount of the dip-in powder to be taken, and at the same time, it will affect the anti-smudge performance of the dip-in eyeliner.

[0011] Preferably, the moisturizing agent is one or more of propylene glycol, butylene glycol, pentylene glycol and glycerol. Considering irritation and safety, preferably, the moisturizing agent comprises glycerol and butylene glycol in a weight ratio of 1:(1-3).

[0012] Preferably, the preservative is one or more of formaldehyde or formaldehyde donor preservatives, paraben preservatives, isothiazolinone preservatives, phenol preservatives and acid preservatives. Considering irritation and safety, preferably, the preservative includes phenoxyethanol and caprylyl glycol in a weight ratio of (1.8-1.9):1.

[0013] Preferably, the adhesive is one or more of polyvinyl pyrrolidone, polyvinyl alcohol, gum arabic, graphene and polyacrylate cross-linked polymer-6.

[0014] Preferably, the adhesive is polyvinyl pyrrolidone or polyacrylate cross-linked polymer-6, and the molecular weights of the polyvinyl pyrrolidone and polyacrylate cross-linked polymer-6 are both 500,000-1,000,000.

[0015] Preferably, the film former is one or more of acrylic resin emulsion, styrene / acrylic resin emulsion, ethylhexyl acrylate / acrylic resin emulsion and polyurethane resin emulsion.

[0016] Preferably, the film former comprises acrylic resin emulsion and styrene / acrylic resin emulsion. The acrylic resin emulsion and styrene / acrylic resin emulsion both have a solid content of 35-55%, preferably 40-50%, and a viscosity of 100-800 cps.

[0017] Preferably, the overall molecular weight of the film-forming agent is greater than 20,000, and the acrylic copolymer chain segment accounts for 30-50% of the overall copolymer. The particle size after emulsification and dispersion in water is less than 200 nm.

[0018] In a second aspect, the present application provides a method for preparing a dip-type eyeliner, which adopts the following technical solution: A method for preparing a dip-in eyeliner comprises the following steps: S1. Preparation of Dipping Powder At a speed of 1000-2000 rpm / min, the moisturizer, preservative, binder and water are mixed evenly, and then the colorant and filler are added and the speed is increased to 18000-20000 rpm / min, and shear stirring is performed for 5-10 minutes to obtain a dipping powder; S2. Preparation of liquid eyeliner At a rotation speed of 1000-2000 rpm / min, the moisturizer, preservative and water are mixed evenly, and then the film-forming agent is added and stirred for 5-10 minutes to obtain the eyeliner liquid, and then the eyeliner liquid is assembled with a container to obtain an eyeliner liquid pen.

[0019] In summary, this application has the following beneficial technical effects: 1. The present application mixes a high proportion of colorant and filler, moisturizer, preservative, adhesive and water to form a dip-in powder, mixes a high proportion of film-forming agent and moisturizer, preservative and water, and then assembles them with a container to form an eyeliner liquid pen, and uses the eyeliner liquid pen in combination with the dip-in powder, so that the dip-in eyeliner has both high color development and strong water resistance and smudge resistance, greatly improving the long-lasting makeup holding ability of the dip-in eyeliner; 2. The dip-in powder of the present application not only increases the proportion of colorant, up to 55%, so that the dip-in eyeliner has an excellent color development effect, but also adds fillers of different particle types, so that the dip-in eyeliner also shows a silky skin feel, and under long-term makeup, the sebum secreted on the skin surface can be absorbed by the filler, thereby increasing the anti-smudge performance of the dip-in eyeliner; 3. Since the liquid eyeliner of the present application does not need to add colorant ingredients, the permeability of particles is significantly improved, and the addition ratio of film-forming agent is greatly increased, up to 80%, thereby reducing volatile components, and being able to quickly form a dense film layer to cover the powder, thereby further improving the water resistance of the dip-type eyeliner.

[0033] Example 6 A method for preparing a dip-in eyeliner is different from that of Example 3 in that, in step S1, during the preparation of the dip-in powder, the weight ratio of the porous particles to the non-porous particles of the spherical silicon powder is 2:1, and the rest is the same as that of Example 3.

[0034] Example 7 A method for preparing a dip-in eyeliner is different from that of Example 3 in that, in step S1, during the preparation of the dip-in powder, the weight ratio of the porous particles to the non-porous particles of the spherical silicon powder is 1:5, and the rest is the same as that of Example 3.

[0035] Example 8 A method for preparing a dip-in eyeliner is different from that of Example 3 in that, in step S1, in the preparation process of the dip-in powder, only porous particles of spherical silicon powder are used, and the rest is the same as that of Example 3.

[0036] Example 9 A method for preparing a dip-in eyeliner is different from that of Example 3 in that, in step S1, during the preparation of the dip-in powder, only non-porous particles of spherical silicon powder are used, and the rest is the same as that of Example 3.

[0037] Comparative Example 1 The difference from Example 3 is that in the preparation process of the dipping powder in step S1, spherical silicon powder is not added, the amount of colorant used is 75 kg, and the rest is the same as Example 3.

[0038] Performance Testing 1. Waterproofness: After the dip-in eyeliner prepared in the above-mentioned embodiment and comparative example is used to draw a line on the skin and completely dried, it is rinsed with water at the same flow rate for 3 minutes to observe the color fading of the pigment. If there is no color fading, the water resistance is judged to be strong; if there is slight color fading, the water resistance is judged to be relatively strong; if most of the color is faded, the water resistance is judged to be weak.

[0039] 2. Oil resistance: The dip-type eyeliner prepared in the above embodiments and comparative examples was applied on a glass slide, and after drying to form a film, it was placed in a beaker containing isononyl isononanoate and immersed for 30 minutes. The color fading of the pigment was observed. If there was no fading, bleeding or blooming, it was judged as strong; if there was slight fading, bleeding or blooming, it was judged as relatively strong; if most of the fading, bleeding or blooming was observed, it was judged as weak.

[0040] 3. Skin feel after application: Make up with the dip-type eyeliners prepared in the above embodiments and comparative examples, and record the skin feel experience.

[0041] The above performance tests are recorded in Table 1.

[0042] Table 1 Performance test results As can be seen from Table 1, the dip-in eyeliners prepared in Examples 1-5 of the present application have almost no color fading or slight color fading in the experiments of water resistance and oil resistance, and have a good skin feel without obvious abnormalities when applied, and are found to have very good color development effects through observation. This shows that the dip-in eyeliners made of the present application using the eyeliner liquid pen and the dip-in powder have both high color development and strong water resistance and smudge resistance, strong long-lasting makeup holding ability, and also show a silky skin feel and a good feel when used.

[0043] The difference between Example 6-7 and Example 3 is that the ratio of the spherical silicon powder of the porous particles and the spherical silicon powder of the non-porous particles is different. It can be seen from Table 1 that when the proportion of the porous particles is too large, the skin feel of the dip-in eyeliner will be significantly affected, and when the proportion of the non-porous particles is too large, the waterproof and oil-resistant performance of the dip-in eyeliner will be weakened, and the skin feel will also deteriorate. Experimental data show that further optimizing the ratio of the porous particles and the non-porous particles can enhance the waterproof and oil-resistant performance of the dip-in eyeliner and improve its skin feel.

[0044] The difference between Example 8-9 and Example 3 is that only spherical silicon powder with porous particles or only spherical silicon powder with non-porous particles is used. It can be seen from Table 1 that when only spherical silicon powder with porous particles is used, the skin feel of the dip-in eyeliner is seriously affected, and when only spherical silicon powder with non-porous particles is used, the waterproof and oil-resistant properties of the dip-in eyeliner are greatly reduced, and the comfort of the skin feel is weakened. Experimental data show that the use of a mixture of spherical silicon powder with porous particles and spherical silicon powder with non-porous particles can make the dip-in eyeliner have good waterproof and oil-resistant properties, while maintaining a silky skin feel, and having a good feel in use.

[0045] The difference between Comparative Example 1 and Example 3 is that the spherical silica powder is not added to the dip-in powder and the amount of the colorant is increased. It can be seen from Table 1 that when the spherical silica powder is not added, the waterproof and oil-resistant ability and skin feel of the dip-in eyeliner are significantly deteriorated. Experimental data show that the application adds a filler and a colorant to the dip-in powder, which can make the dip-in eyeliner show a silky skin feel and enhance the waterproof and anti-smudge performance of the dip-in eyeliner.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
