Description

Cosmetic composition {COSMETIC COMPOSITION}

This description relates to cosmetic compositions.

Makeup products specifically designed for application under or around the eyes to conceal visible lines, wrinkles and undesirable pigmentation have enjoyed considerable popularity in recent years. These products are called concealers, and most are sold in small tubes or containers, often equipped with an applicator. This is applied in a very small amount to the area intended to be hidden or corrected. What makes a concealer effective is its ability to hide imperfections, which in turn makes it difficult to replace the role of a concealer with color cosmetics that are not designed to hide imperfections, so concealers must have greater coverage and opacity than color cosmetics. However, most concealers tend to have a high viscosity, which reduces the feeling of use, and are opaque because they contain a significant amount of titanium dioxide or fillers. Most concealers improve the adhesion of the coloring composition to the skin, which can actually cause skin problems. It can also happen.

On the other hand, foundation makeup is a cosmetic product intended to provide color correction and smoothness by applying a colored film or other ingredients to the skin. Foundation makeup tends to be lighter in texture and less opaque than concealer. As many users of both foundations and concealers know, they are not interchangeable. If you use concealer rather than foundation makeup on your entire face, it will feel like you are wearing a mask and will give your skin an uncomfortable feeling. Furthermore, if the concealer hardens on the surface of your face and cracks form, it will not perform its role properly as a concealer. It becomes impossible. Additionally, if you use regular foundation makeup rather than concealer under and around the eye area, you will have minimal or no coverage, which can sometimes cause your eye makeup and mascara to smudge, giving onlookers the impression that your eye makeup is scary. Therefore, it is not suitable for use in general situations. In other words, foundation makeup is insufficient to perform its role as a concealer.

In addition, all concealers currently sold on the market have all of the conventional problems of the aforementioned concealers, and although there is an increasing demand for concealers that color the facial skin and eye area, have adequate coverage, and have optimal aesthetics and coverage effects, However, research on cosmetic compositions for concealers is still very limited.

One embodiment is to provide a cosmetic composition for concealer with excellent covering effect.

According to one embodiment, a cosmetic composition is provided that includes an aqueous phase component and a colorant, wherein the aqueous phase component consists of a film former, a dispersant, a moisture evaporator, and purified water, and has a viscosity of 3000 cps or less.

Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein.

In this specification, when a part of a layer, membrane, region, plate, etc. is said to be “on” another part, this includes not only the case where it is “right on” the other part, but also the case where there is another part in between. Conversely, when a part is said to be “right on top” of another part, it means that there is no other part in between.

Unless otherwise defined herein, “combination” means mixing or copolymerization. Additionally, “copolymerization” refers to block copolymerization to random copolymerization, and “copolymer” refers to block copolymerization to random copolymerization.

Hereinafter, a cosmetic composition according to one embodiment will be described.

The cosmetic composition according to one embodiment includes an aqueous phase component and a colorant, and the aqueous phase component consists of a film former, a dispersant, a moisture evaporator, and purified water, and has a low viscosity of 3000 cps or less.

Water-in-oil makeup cosmetics, which make up most of the cosmetic compositions for concealers, have the advantage of excellent spreadability and the ability to disperse a high content of pigment, resulting in high covering power. However, the oil resistance of the makeup film is insufficient, so when used for concealer purposes, the next step is It has the disadvantage of being easily removed by water-in-oil makeup cosmetics and having a low concealing effect. Accordingly, high viscosity water-dispersed makeup cosmetics rather than water-in-oil type have been proposed as a new alternative. This is because it has the advantage of forming a concealer film with excellent oil and water resistance. However, there is a disadvantage that it takes a long time for the film film to be formed due to the influence of viscosity, which causes another problem that was not previously thought of.

According to one embodiment, by providing a low-viscosity water-dispersed makeup cosmetic containing a hydratable film former and a pigment, a film film is quickly formed and has excellent oil and water resistance, so that it can be layered with the next stage of makeup cosmetic. Since a superior covering effect can be achieved, all of the above-mentioned problems can be solved, thereby providing a cosmetic composition that is very suitable for concealer use. Specifically, rapid film formation is possible, resulting in excellent oil and water resistance, and when the next step cosmetic is applied, the film film is not erased, allowing for an excellent covering effect.

The cosmetic composition according to one embodiment may also not contain any oily components such as oil. Since it does not contain any of the oil components, even if the cosmetic composition according to one embodiment is applied first, the cosmetic composition according to one embodiment is not easily removed by the water-in-oil type makeup cosmetic in the next step, and from this, the cosmetic composition according to one embodiment It can be seen that the composition is very suitable for use as a concealer.

The film forming agent is a hydratable film forming agent and may be a mixture of three different compounds. For example, the film forming agent is polyvinyl alcohol (PVA), polyvinylpyrrolidine (PVP), polyvinyl acetate, polyurethane-10, polyurethane-14, butylacrylate/hydroxypropyldimethicone acrylate copolymer. , Acrylate copolymer, acrylate/C12-22 alkyl methacrylate copolymer, ammonium acrylate copolymer, styrene/acrylate/ammonium methacrylate copolymer, methacryloylethyl betaine/acrylate copolymer, It may be a mixture of three compounds selected from the group consisting of acrylate/stearylacrylate/dimethicone methacrylate copolymer and acrylate/polytrimethylsiloxymethacrylate copolymer.

For example, the film forming agent may be a mixture of polyvinyl alcohol, acrylate copolymer, and styrene/acrylate/ammonium methacrylate copolymer.

The content of polyvinyl alcohol in the film forming agent may be less than the content of each of the other two compounds, such as the acrylate copolymer and the styrene/acrylate/ammonium methacrylate copolymer.

Additionally, the polyvinyl alcohol may be included in an amount of 0.1% to 3% by weight based on the total amount of the cosmetic composition. When the polyvinyl alcohol is contained in an amount of less than 0.1% by weight based on the total amount of the cosmetic composition, film formation is difficult, and when the polyvinyl alcohol is contained in an amount exceeding 3% by weight based on the total amount of the cosmetic composition, the phenomenon of tearing of the film occurs. Not desirable.

The acrylate copolymer and styrene/acrylate/ammonium methacrylate copolymer in the film forming agent may each independently be included in an amount of 1% to 10% by weight based on the total amount of the cosmetic composition, and in this case, the polyvinyl alcohol is It may be included in a smaller amount than each of the acrylate copolymer and the styrene/acrylate/ammonium methacrylate copolymer. If the acrylate copolymer is included in less than 1% by weight based on the total amount of the cosmetic composition, the film forming ability is reduced, and if the acrylate copolymer is included in more than 10% by weight based on the total amount of the cosmetic composition, it dries the skin. This is not desirable as it provides a feeling of tightness on the skin. When the styrene/acrylate/ammonium methacrylate copolymer is included in less than 1% by weight based on the total amount of the cosmetic composition, the film forming ability is also reduced, and the styrene/acrylate/ammonium methacrylate copolymer is used in the cosmetic composition. If it is included in more than 10% by weight based on the total amount of the composition, it is undesirable because spreadability is impaired.

When the film-forming agent has the above-mentioned composition, the cosmetic composition can have a viscosity of 3000 cps or less and can form a film quickly, and not only has excellent water and oil resistance, but also can have an excellent concealing effect.

The film forming agent may be included in an amount of 1% to 20% by weight based on the total amount of the cosmetic composition. If the film former is included in less than 1% by weight based on the total amount of the cosmetic composition, the content of the film former is too small and the film forming ability is reduced, and if the film former is included in more than 20% by weight based on the total amount of the cosmetic composition, the film forming agent is reduced. If the content of the forming agent is too high, the stickiness may increase and the feeling of use may deteriorate.

Meanwhile, since the cosmetic composition according to one embodiment has a viscosity of 3000 cps or less, it does not include a separate thickener. For example, if a small amount of a separate thickener is included, oil resistance can be improved, but the viscosity increases significantly to a value higher than 3000 cps, which inhibits the drying speed of the components that make up the cosmetic composition and slows down the film formation speed. This may lead to a decrease in the concealing effect.

The dispersant may include a cellulose-based compound.

For example, the dispersant may include microcrystalline cellulose, cellulose gum, or a combination thereof, but is not necessarily limited thereto.

The moisture evaporating agent may include an alcohol-based compound.

For example, the alcohol-based compound may be a mixture of butylene glycol, ethanol, and phenol ethanol.

The colorant may be a metal oxide whose surface has been treated with silica.

For example, the colorant may be a mixture of two or more compounds, and the compound may be a metal oxide surface-treated with silica.

For example, the colorant may be a mixture of titanium oxide surface-treated with silica, yellow iron oxide surface-treated with silica, red iron oxide surface-treated with silica, and black iron oxide surface-treated with silica.

In the case of titanium oxide surface-treated with silica, it is preferable that the particle size is 400 nm to 600 nm to sufficiently exert covering power, and it may be preferably contained in 0.5% by weight to 25% by weight based on the total amount of the cosmetic composition. If the titanium oxide surface-treated with silica is included in an amount of less than 0.5% by weight based on the total amount of the cosmetic composition, the covering power is not properly demonstrated, and if the titanium oxide surface-treated with the silica is contained in an amount of less than 0.5% by weight based on the total amount of the cosmetic composition, In this case, the mixing limit of titanium oxide is exceeded.

In addition, in the case of yellow, red and black iron oxides surface-treated with silica, the content is determined depending on the color, and the sum is 0.01% by weight to 10% by weight, for example, 0.1% by weight to 5% by weight, based on the total amount of the cosmetic composition. may be included. If the yellow, red, and black iron oxides surface-treated with silica are included in an amount of less than 0.01% by weight based on the total amount of the cosmetic composition, the covering power is not properly demonstrated, and the yellow, red, and black iron oxides surface-treated with the silica are included in the total amount of the cosmetic composition. If it exceeds 10% by weight, the dispersibility decreases, affecting the stability of the formulation.

The colorant is prepared by dispersing titanium oxide and yellow, red, and black iron oxide, adding a precursor capable of forming silica (e.g., tetraethoxysilane, etc.), and dispersing it at a temperature of 50°C to 400°C for 1 hour to 6 hours. It can be obtained by heat treatment and hydrolysis, but the manufacturing method of the colorant is not necessarily limited to this.

The purified water may be included as a remaining amount, for example, 10% by weight to 90% by weight, for example, 30% by weight to 70% by weight, based on the total amount of the cosmetic composition. If the purified water is included in less than 10% by weight based on the total amount of the cosmetic composition, the water content is small, so the dispersibility of the pigment is poor and the feeling of moisture is not felt, which worsens the feeling of use. The purified water is 90% by weight based on the total amount of the cosmetic composition. If it is included in excess of , the water content is too high, causing problems in mixing other raw materials such as powder or oil.

The cosmetic composition according to one embodiment may be a water-dispersible cosmetic composition.

The cosmetic composition according to one embodiment may be a cosmetic composition for concealer containing a pigment. For example, the cosmetic composition may be formulated as a concealer, but is not necessarily limited thereto.

Hereinafter, the contents of the present invention will be described in more detail through examples and comparative examples. These examples are provided to understand the content of the present invention, but the scope of the present invention is not limited to these examples and test examples, and modifications, substitutions, and insertions commonly known in the art can be performed. It can be done, and this is also included in the scope of the present invention.

Test Example 1: Viscosity

The viscosity of the cosmetic compositions of Example 1 and Comparative Examples 1 to 8 prepared in the above Preparation Example was compared and evaluated. After each sample was stored in a thermostat at 30°C for 24 hours, the viscosity was measured using a Brookfield viscometer (63 spindle, 12 rpm), and the results are shown in Table 3 below.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Comparative Example 7 Comparative Example 8 Viscosity (cps) 2800 3400 2300 2100 3100 2900 2100 13000 7000

Test Example 2: Film Formation Rate

The film formation rates of the cosmetic compositions of Example 1 and Comparative Examples 1 to 8 prepared in the above Preparation Example were compared and evaluated. 0.1 g of each of the above cosmetic compositions was taken and applied to glossy paper using a 0.1mm film applicator. Afterwards, the time taken for complete drying without the contents coming out was observed and recorded by touching it with a finger, and the results are shown in Table 4 below.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Comparative Example 7 Comparative Example 8 film formation rate 8 minutes 49 seconds 11 minutes 19 seconds 8 minutes 27 seconds 7 minutes 24 seconds 9 minutes 27 seconds 10 minutes 42 seconds 8 minutes 17 seconds 17 minutes 51 seconds Not measurable (over 48 hours)

As can be seen in Table 4 above, in the case of Comparative Example 8, it can be seen that the large amount of oil on the external wound was not completely dried, so the film forming ability was lower than that of the water dispersion formulation.

In the case of Comparative Example 7, it was confirmed that the evaporation rate of the water phase was inhibited compared to Example 1 due to the high viscosity formulation increased by the water phase thickener, and the film formation rate was also slowed.

Test Example 3: Comparison of tearing phenomenon

In order to check the tearing phenomenon of the cosmetic compositions of Example 1 and Comparative Examples 1 to 8 prepared in the above Preparation Example, the cosmetic compositions of Example 1 and Comparative Examples 1 to 8 were applied to artificial leather (250mmX250mm), respectively. Apply and dry completely. Afterwards, using an applicator attached to artificial leather, pressure was applied and pushed onto the above makeup film with the same force. The degree of tearing before and after pressure was applied was evaluated and determined based on the following four-step criteria, and the results are shown in Table 5 below.

◎: No change from the beginning.

○: There is little change from the beginning, and there are very fine tear marks.

△: Tearing occurs in a certain part.

X: Tearing occurs in more than half of the application area.

As can be seen in Table 5 above, in the case of Comparative Example 1, Comparative Example 4, and Comparative Example 5 in which an excessive amount (3% by weight or more) of polyvinyl alcohol (PVA) was used and only one or two types of film forming agents were used, after preparation It was confirmed that the wear resistance of the contents decreased and tearing occurred. In addition, in Comparative Examples 2, 3, and 6, which did not use polyvinyl alcohol as a film forming agent, the film itself was formed too thin, so it seemed to have a good tearing phenomenon, and the film itself was too thin, so it had insufficient coverage, so it was used as a concealer. It was confirmed that commercialization was impossible.

Test Example 4: Water resistance and oil resistance

In order to confirm the water resistance and oil resistance of the cosmetic composition prepared in the above production example, Example 1, Comparative Example 7, and Comparative Example 8 were each applied to a glass plate to a thickness of 40 μm using an applicator, dried, and then washed in purified water at room temperature. Or soak in caprylic/capric triglyceride. The surface condition after 30 minutes of immersion was evaluated using the following four-step criteria, and the results are shown in Table 6 below.

○: There is a slightly melted part, and it is not peeled, but slightly swollen.

△: Quite melted and peeled off.

X: All are melted, peeled off or melted.

From Table 6, it can be seen that the cosmetic composition according to Example 1 is excellent in both water resistance and oil resistance.

Test Example 5: Comparison of concealing effects before and after foundation application

In order to confirm the concealing effect of the cosmetic composition prepared in the above Preparation Example, the cosmetic composition according to Example 1 and Comparative Examples 1 to 8 were applied to artificial leather (250mmX250mm) with writing on it, respectively, and dried. After 10 minutes, 1 mg of water-in-oil foundation was additionally applied on the makeup film using an applicator. The concealing effect before and after foundation application was evaluated based on the following four-step criteria, and the results are shown in Table 7 and Figures 1 to 18.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Comparative Example 7 Comparative Example 8 Before applying foundation ◎ ◎ X X X ◎ X ○ ○ After applying foundation ○ △ X X X △ X X X

◎: The text is completely invisible.

○: The text is barely visible.

△: The text is slightly visible.

X: The text is clearly visible.

From Table 7 and Figures 1 to 18, it can be seen that the cosmetic composition according to Example 1 has an excellent concealing effect.

Summarizing the above test examples, it can be confirmed that the cosmetic composition according to Example 1 forms a film quickly, has strong oil resistance and durability, and shows excellent coverage without being moved even when applying the next step of cosmetics, making it suitable for use as a concealer. . On the other hand, the cosmetic compositions according to Comparative Example 1, Comparative Example 4, and Comparative Example 5 cannot be commercialized due to tearing, and the cosmetic compositions according to Comparative Example 2, Comparative Example 3, and Comparative Example 6 have a very thin film film, so the covering power is poor. It cannot be commercialized due to a shortage, and the cosmetic composition according to Comparative Example 7 has too high a viscosity, so the film drying speed is very slow, and the existing concealing makeup film is erased when applying the next step of the cosmetic, making it unsuitable for use as a concealer. It can be seen that the cosmetic composition according to 8 has poor oil resistance and is easily mixed and erased when applying the next step of cosmetics, making it unsuitable for use as a concealer.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements can be made by those skilled in the art using the basic concept of the present invention as defined in the following claims. It falls within the scope of invention rights.
