Abstract

The present invention relates to an eye makeup composition and, more specifically, to a gel thickener-free oil-dispersion typed eye makeup composition which comprises a volatile oil, a pigment, a spherical powder, and a film former. According to the present invention, since the viscosity of the eye makeup composition is adjusted by controlling the content of the volatile oil, the spherical powder, the film former, and the pigment, a separate gel-like thickener is not included so that a high-temperature dispersion process can be omitted, thereby being cost-effective. In addition, volatilization of the volatile oil is minimized, thereby solving formulation problems of water dispersion type products. In addition, the eye makeup composition facilitates attachment of artificial eyelashes due to high magnetism and provides excellent discharge stability, high blackness, excellent water resistance, and durability due to dispensing stability.

Description

Gel thickener-free oil-dispersion typed cosmetic composition for eye makeup

The present invention relates to an eye makeup composition, and more particularly, to an oil-dispersion type eye makeup composition comprising a volatile oil, a pigment, a spherical powder, and a film former.

The eye makeup composition used around the eyes should be carefully selected raw materials for fear of potential irritation. In particular, since eyeliner is a cosmetic that is applied to the most sensitive area, the eye, special attention to safety is required. However, there are currently insufficient high-adhesion type eye makeup products that are easy to attach artificial eyelashes including magnets and have high durability and water resistance.

Such eyeliner can be divided into an oil-dispersion type and a water-dispersion type according to the formulation, and the oil-dispersion type formulation can be classified into a liquid type and a balm type. In the balm type, the contents are directly exposed to the air, which causes surface hardening, and it is difficult to apply the fine parts around the eyes, and it is inconvenient to use a separate brush. Due to these shortcomings, liquid type eyeliner with a soft feel, fast drying speed, and convenience when applied is mainly being developed.

The liquid type has the advantage that the brush is impregnated with the contents, so it is soft and can be applied to the finer parts. Among them, the water dispersion type contains a water-soluble polymer or a polymer emulsion as a film forming agent, and when the polymer material is exposed to oil or moisture for a long time, the film film is easily peeled off, and it cannot have sufficient durability such as water resistance, oil resistance, and friction resistance. Until now, most of the products with the function of attaching artificial eyelashes are mainly of the water-dispersion type, which dries slowly, and some of the contents are torn off. In addition, it is applied in a thick or uneven form for re-applied use during correction makeup and has a rather heavy feeling of use, which causes wrinkles around the eyes when artificial eyelashes are attached for a long time.

Among the inorganic pigments used in makeup products, red iron oxide, black iron oxide, and yellow iron oxide are red, black, and yellow colored pigments of different colors. Although iron oxide pigments are produced by pulverizing and calcining naturally occurring pigments, they are currently manufactured by wet synthesis using iron sulfate or iron chloride as raw materials, and thus have magnetic properties during the process. Because it exhibits magnetism, the dispersibility in water is not excellent, and thus the color clarity is somewhat deteriorated, and there are disadvantages in that the change with time due to re-agglomeration is severe. As the amount of the dye is increased, the dispersibility is improved and the vividness of the color is improved.

In addition, in the case of oil-dispersion type eye makeup products, various thickeners are used to increase the viscosity of the cosmetic to stably maintain the cosmetic shape. These thickeners are used by dissolving them in volatile oil, and the process of dispersing the raw materials including the thickener is mostly performed at a high temperature of over 50°C. During the raw material input process during high-temperature operation, the volatile oil volatilizes due to repeated opening and closing of the raw material dispersion tank lid, and the content viscosity deviation occurs due to the volatilization of the volatile oil. There was also a problem in that undispersed floating matter remained when dispersion was completed.

Laid-Open Patent Publication No. 10-2014-0000504 (2014.01.03)

It is an object of the present invention to provide an oil-dispersion type eye makeup product that solves the slow drying speed and low durability of the water dispersion type eye makeup product, the film tear phenomenon, minimizes eye irritation, and has high durability and water resistance.

Another object of the present invention is to provide an oil-dispersible eye makeup composition having excellent dispersibility even without a high-temperature dispersion process of raw materials.

Another object of the present invention is to provide a method for preparing an oil-dispersible eye makeup composition that does not include a high-temperature dispersion process.

In order to solve the above problems, the inventors of the present invention studied the combinations and contents of various volatile oils, film formers, spherical powders and pigments. Thus, the present invention was completed after confirming that it has a high degree of blackness, improves the feeling of use and adhesion, and also has excellent stability.

The present invention provides an oil-dispersible eye makeup composition comprising a volatile oil, a film former, a spherical powder, and a pigment.

The volatile oil of the present invention may be a silicone oil, an ester-based oil, a branched aliphatic hydrocarbon, and combinations thereof. Specifically, the volatile oil may include disiloxane, methyl trimethicone, isododecane, dimethicone, dimethylpolysiloxane, cyclomethicone, C _10-11 isoparaffin, and isohexadecane It may further include one or more selected from the group consisting of. More specifically, the volatile oil may be disiloxane, methyl trimethicone, isododecane and dimethicone.

The volatile oil may be included in an amount of 20 to 60% by weight based on the total weight of the eye makeup composition. If the volatile oil content is less than 20% by weight, the drying speed is fast and the fixing time of the contents is insufficient, and the spreadability may be deteriorated. Due to its properties, the drying rate is slow, it spreads easily, and the artificial eyelashes have reduced adhesion, which can cause problems that they come off easily.

The film-forming agent of the present invention refers to an agent that prevents makeup removal or discoloration, prevents bias of active ingredients such as UV absorbers, and improves durability by forming a film on the skin, and most of the film-forming agent is a high molecular compound. , a silicone resin, a fluorine-based resin, or an acrylic resin may be used. The film forming agent may be included in an amount of 10 to 40% by weight based on the total weight of the eye makeup composition.

Specifically, the film forming agent used in one embodiment of the present invention may be trimethylsiloxysilicate, trimethylsiloxysilicate/dimethiconol crosspolymer, and polyisobutene.

Here, the trimethylsiloxysilicate is a silicone film former effective in improving the fixing power, durability, and smearing under the eyes of eye makeup products, and it is not sticky after drying and can form a strong film. In a specific embodiment of the present invention, the trimethylsiloxysilicate may be included in an amount of 5.0 to 20% by weight based on the total weight of the eye makeup composition, and when it is less than 5% by weight, the effect is insignificant, and when it is more than 20% by weight, it is too hard. There is a problem in that usability is deteriorated.

The trimethylsiloxysilicate / dimethiconol crosspolymer is slightly sticky compared to trimethylsiloxysilicate, and is flexible and durable even for eye movements, so it can form a strong film when used with trimethylsiloxysilicate. . In a specific embodiment of the present invention, the trimethylsiloxysilicate/dimethiconol crosspolymer may be included in an amount of 3.0 to 10% by weight based on the total weight of the eye makeup composition, and when it is less than 3% by weight, the effect is insufficient and 10% by weight %, there is a problem in that it is sticky and the drying speed is slow.

The polyisobutene may spread thickly, exhibit a sticky feeling, and be used as a binder to form a film feeling and increase adhesion. In a specific embodiment of the present invention, the polyisobutene may include 3.0 to 10% by weight based on the total weight of the eye makeup composition, and when it is less than 3% by weight, the adhesion durability after drying is not excellent, and the contents are thin There is a problem of spreading faster, and when it exceeds 10% by weight, the drying rate is slow, it does not spread evenly, and the adhesion durability after drying is high, but there is a problem that stickiness occurs around the eyes.

The spherical powder of the present invention refers to a powder having a spherical particle shape, and any spherical powder used in cosmetics in the art may be used. Specifically, the spherical powder is silica, polymethylmethacrylate, HDI/trimethylolhexyllactone crosspolymer (HDI/Trimethylol Hexyllactone Crosspolymer), methylmethacrylate crosspolymer, poly It may be at least one selected from the group consisting of methylsilsesquioxane, polypropylsilsesquioxane, silicadimethylsilylate, and nylon, but is not limited thereto. In a specific embodiment of the present invention, the spherical powder may be methyl methacrylate crosspolymer, polypropylsilsesquioxane, silica, and silica dimethyl silylate. In the present invention, the spherical powder may be included in 2.0 to 15% by weight based on the total weight of the eye makeup composition, and when it is less than 2% by weight, the role of alleviating smearing and stickiness around the eyes and forming viscosity is insufficient, 15% by weight When it exceeds, it was confirmed that the viscosity was too high, the application amount was large, the application was not uniformly, and the adhesive force for attaching the artificial eyelashes was low.

Among the spherical powders, the methyl methacrylate crosspolymer may be included in an amount of 0.5 to 10% by weight based on the total weight of the eye makeup composition. When the amount of methyl methacrylate crosspolymer is less than 0.5% by weight, it is thinly applied to the skin as a thin liquid with low viscosity, and there is a problem of stickiness and smearing around the eyes after drying. It is applied thinly, and the film-forming ability is increased, but it dries too quickly, making it difficult to correct and make-up around the eyes, and pulling around the eyes may occur.

Among spherical powders, silica-based powders increase the viscosity, but do not increase the viscosity so that the bond is hard, and there is a concern that formulation stability may be deteriorated due to the influence of temperature. It increases the viscosity while making the bond between the film and the film forming agent relatively hard. Accordingly, it helps the formulation stability and helps to improve the uniformity of application and spreadability.

The pigment of the present invention refers to a colorant capable of imparting color, and may specifically be an inorganic pigment. More specifically, the inorganic pigment of the present invention is iron oxide characterized in that it exhibits magnetism, and may be representatively yellow, black and red iron oxide. In a specific embodiment of the present invention, the iron oxide (powder) may be included in an amount of 20 to 60% by weight based on the total weight of the eye makeup composition, and when it is less than 20% by weight, it exhibits low magnetic properties, has a very dilute appearance, and has a very fast drying rate. There is difficulty in applying makeup, pulling around the eyes may occur, there is difficulty in attaching artificial eyelashes, and they come off easily. If it exceeds 60% by weight, the viscosity becomes too high, and it is heavily applied around the eyes and spreads thickly, so the drying rate is very slow, the flexibility of the film is poor, and there is a problem that the powder falls off.

It may further include oils and emulsifiers commonly used in the eye makeup composition, and may be used without limitation as long as it can impart curling power, durability, and moisturizing power to the eyes.

The eye makeup composition of the present invention does not contain a gel-like thickener that requires a high-temperature dispersion process during manufacture, wherein the gel-like thickener is a thickener in a powder state, mixed with an aqueous phase or an oil phase, and is a gel in the present invention. The thickener may be a hectorite-based water-insoluble organic thickener, and specifically, hectorite, disteadimonium hectorite, quaternium-18 hectorite, and stearalkonium hectorite may be used. In addition, it may be a water-soluble thickener such as hydroxyethylcellulose, polyvinylpyrrolidone, xanthan gum, magnesium aluminum silicate. Therefore, since the gel thickener is mixed in the oil phase or the aqueous phase in a powder state, a dispersion process at a high temperature of 50° C. or higher is necessarily required to disperse it.

In the present invention, the eye makeup composition may be applied to both mascara and eyeliner formulations, and specifically may be an oil-dispersion liquid type eyeliner formulation.

In addition, the present invention provides a method for preparing an oil-dispersible eye makeup composition.

Specifically, referring to FIG. 1 , the method includes mixing and dispersing a volatile oil and a film forming agent to prepare a liquid base (S1); dispersing the spherical powder into the liquid base (S2); and mixing and dispersing the color base in the liquid base in which the spherical powder is dispersed (S3).

Descriptions of the types and contents of the volatile oil, the film former, the spherical powder, and the pigment used in the method are the same as those described in the composition, and thus are omitted in order to prevent overlapping descriptions.

The color base of step S3 may be prepared by mixing a pigment with volatile oil, and specifically, by mixing iron oxide as a pigment in a solvent in which dimethicone, methyl trimethicone and trimethylsiloxysilicate are mixed, a three-step roll It may be uniformly dispersed using

The method of the present invention does not use a gel-like thickener, so it is not necessary to separately proceed with a high-temperature dispersion process or leave it at room temperature, so it is cost-effective, and by minimizing volatilization of volatile oils, including isododecane, due to high temperature during the dispersion operation. It is possible to increase the stability of the product, and it is possible to prepare a highly-adhesive eye makeup composition that minimizes powder agglomeration by not using a gel-like thickener.

In addition, in the present invention, the dispersion rotation speed in the step (S1) is 400 to 1000 rpm, the dispersion temperature is less than 30 to 50 ℃, the dispersion time is preferably 5 to 15 minutes. The temperature performed in the steps (S2) and (S3) is less than 30 to 50 °C. The dispersion time is preferably 5 to 15 minutes.

In a specific embodiment of the present invention, the step (S1) was performed at a rotation speed of 600 rpm, a dispersion temperature of 40° C., and a dispersion time of 10 minutes, and the steps (S2) and (S3) were performed at a rotation speed of 600 rpm, a dispersion temperature of 40 ℃, dispersion time was carried out for 10 minutes.

In order to prevent the volatile oil from volatilizing, it is preferable that all steps of the method are carried out at less than 50°C.

The eye makeup composition of the present invention is characterized in that it does not add a separate gel-like thickener by controlling the viscosity by controlling the content of volatile oil, spherical powder, film former, and pigment, so the high temperature dispersion process can be omitted. It is cost-effective, minimizes volatilization of volatile oil, solves the formulation problems of water-dispersible products, exhibits high magnetic properties, so it is easy to attach artificial eyelashes, and has high blackness and excellent water resistance and durability due to excellent discharge stability characterized in that

The preparation of the specific eyeliner composition was carried out as follows:

In beaker 1, disiloxane, methyltrimethicone, isododecane and dimethicone as volatile oils, trimethylsiloxysilicate, trimethylsiloxysilicate/dimethiconol crosspolymer, and polyisobutene as film formers were added and mixed. In particular, this process was carried out under conditions of a rotation speed of 600 rpm, a dispersion temperature of 40° C., and a dispersion time of 10 minutes to facilitate mixing and dispersion of polyisobutene. At this time, it is important to maintain the condition of less than 50 ℃ so that the volatile oil is not volatilized (S1).

Then, the spherical powder of methyl methacrylate crosspolymer, polypropylsilsesquioxane, silica and silica dimethyl silylate were slowly added to the beaker 1 under the conditions of a rotation speed of 600 rpm, a dispersion temperature of 40° C., and a dispersion time of 10 minutes. It was evenly dispersed under (S2).

Then, black iron oxide was mixed with a solvent in which dimethicone, methyl trimethicone, and trimethylsiloxysilicate were mixed in the beaker 1, and the color base was evenly dispersed using a three-roll roll, followed by a rotation speed of 600 rpm, dispersion It was uniformly dispersed under the conditions of a temperature of 40° C. and a dispersion time of 10 minutes (S3). After that, it was stirred to 28° C. and cooled to completion.

Experimental Example 1: Content discharge and drying speed check test

The composition of the above example was measured as follows to check the discharge amount, uniformity, and drying speed during application. After filling the contents of each of the above examples in the same liquid brush eyeliner container, discharge of the contents to the brush tip was confirmed. The measurement results of Examples and Comparative Examples according to the black iron oxide content are shown in Table 2 below.

Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Discharge amount at the time of application 0 0 0 Ⅹ 0 Uniformity in application ▲ ▲ 0 Ⅹ 0 drying speed ▲ 0 0 Ⅹ ▲

Legend: 0 -Good (over 80), ▲-Normal (50-80), X-Poor (below 50)

Example 1 is a dilute liquid with the lowest viscosity, so it is not uniformly applied because of a large amount of discharge, and the volatile oil is light and spreads. It dries quickly because it contains a large amount of volatile oil, but some eye irritation or skin tightening may occur, and it was confirmed that it spreads easily by external stimuli after drying. In addition, it was confirmed that it was difficult to attach magnetically attached artificial eyelashes to the eye area due to the low content of black iron oxide, high transparency, low blackness, and insufficient magnetic effect.

Example 2 did not show a significant difference from Example 1 in terms of discharge amount and uniformity, but the viscosity increased as the amount of pigment increased, the drying rate was excellent, and the artificial eyelashes were attached due to higher magnetic properties, but the effect was confirmed to be incomplete.

Example 3 has the best discharge amount, uniformity, and drying speed during application, and when black iron oxide is included in an amount of 40% by weight relative to the total weight of the composition, it is confirmed that the film exhibits flexibility during application and spreads evenly. It is believed that the color pigment, spherical powder, and film former are composed of an appropriate mixing ratio to show the intermediate properties and drying speed of liquid and paste most suitable for attaching artificial eyelashes. Confirmed.

It was confirmed that Example 4 was a paste with the highest viscosity, had a large discharge amount, was thickly applied, had a slow drying rate, spreads easily, and has difficulty in using eyeliner over and over.

In summary, when the black iron oxide content is less than 20% by weight, it exhibits low magnetic properties, is very dilute, and the drying speed is remarkably fast. This is difficult when correcting makeup, pulling around the eyes may occur, it is difficult to attach artificial eyelashes, and it comes off easily. If it exceeds 60% by weight, the viscosity becomes too high, so it is heavily applied around the eyes and spreads thickly, so the drying rate is very slow, the flexibility of the film is lowered, and the powder falls off. Accordingly, the black iron oxide is preferably included in an amount of 20 to 60% by weight, specifically, 30 to 50% by weight, based on the total weight of the eye makeup composition.

Experimental Example 2: Water resistance and durability confirmation test

Eyeliner is a cosmetic used around the eyes, should not be easily erased by sweat, sebum, tears, etc., should have an appropriate drying speed when applied, and should have features that make correction makeup easy. In addition, the film forming agent and the volatile oil should be composed in an appropriate mixing ratio so that it should last for a long time without puckering around the eyes, powder flying, or smearing. Therefore, in Experimental Example 2, it was attempted to confirm the water resistance and durability according to the change in the type and content of the film forming agent, and the composition of the comparative example is shown in Table 3 shown in

In order to evaluate the water resistance and durability of Example 3 and Comparative Examples 2 to 6, which are the compositions of the present invention, 30 ml of purified water was placed in a 50 ml beaker, and a liquid liner brush was used on a slide glass (width X length: 3X1.5cm). Then, the test substance was uniformly applied to an area of about 1 cm², and then the completely dried one was placed in the beaker and left for 1 minute. After standing, it was dried at room temperature for 1 minute, and the process of putting it back into purified water was repeated 3 times to confirm resistance to water resistance. Reproducibility was ensured by performing the entire process three times, and the measurement results are shown in Table 4 below by evaluating whether the original state is maintained for a long time.

Trimethylsiloxysilicate dries quickly and forms a strong film, while trimethylsiloxysilicate/dimethiconol crosspolymer is slightly more flexible and spreads thickly after drying to improve water resistance and durability. do

Example 3 was composed of an appropriate blending ratio of the film-forming agent, dries the fastest and has high fixing power, shows skin flexibility after application due to a thin film feeling after drying, and exhibits the best feeling of use overall with little powder falling off.

It was confirmed that Comparative Example 2 did not contain the main film former material, so water resistance and durability did not last long, the drying rate was very slow, the feeling of use was thin, and smearing under the eyes occurred easily.

Comparative Example 3 and Comparative Example 4 each excluded the main film-forming agent, and Comparative Example 5 had a low content, so the effect was insufficient, and it was confirmed that water resistance, durability, and drying speed were slow.

It was confirmed that Comparative Example 6 had excellent water resistance due to a high content of the main film-forming agent, but had little flexibility in the contents around the eyes, resulting in powder fall and stickiness around the eyes, and a very slow drying rate.

In summary, the eyeliner should be composed of a film forming agent and a volatile oil in an appropriate mixing ratio. Among them, the trimethylsiloxysilicate used as the main film forming agent preferably contains 5.0 to 20% by weight, specifically 10 to 15% by weight. do. The trimethylsiloxysilicate/dimethiconol crosspolymer is preferably included in an amount of 3.0 to 10% by weight, specifically 7 to 10% by weight.

Experimental Example 3: Check the adhesion of artificial eyelashes

In order to enhance the synergistic effect of easily attaching artificial eyelashes by applying the composition of the present invention, a film forming agent showing a feeling of attachment was added together. In order to evaluate the adhesion between the composition of the present invention and the false eyelashes, the compositions of Example 3 and Comparative Example are shown in Table 5 below.

Example 3 is a composition maximizing the effect of magnetic black iron oxide and a film forming agent that increases the durability and water resistance of the composition. showed the results.

Comparative Example 7 does not contain a raw material that improves adhesion, so artificial eyelashes are attached due to the stickiness of other film formers and the magnetism of black iron oxide. confirmed that.

Comparative Example 8 had little effect of adhesion, and Comparative Examples 9 to 10 had a high content of polyisobutene, high viscosity, a large discharge amount, and difficulty in applying an eyeliner over it because it was not uniformly applied. Confirmed.

In addition, the adhesion durability after drying was high, but the stickiness of the contents was high, which gave discomfort to the eye area, and the drying rate was slow, and the eye area smearing occurred.

Therefore, it spreads thickly, shows a sticky feeling, is used as a binder and a viscosity increase agent, and is characterized in that it contains 3.0 to 10 wt % of polyisobutene, which improves film feeling and adhesion durability. If it is less than 3%, the adhesion durability after drying is not excellent, and it is confirmed that the content spreads faster due to a thin appearance. If it exceeds 10%, it is not spread evenly, and the higher the content, the slower the drying rate, the lower the adhesion durability, and there are problems that stickiness and smearing occur.

Experimental Example 4: Testing for smearing and stickiness

After application of the composition of the present invention, it was attempted to check the effect by controlling the content of spherical powder that affects eye smearing and stickiness, and the compositions of Example 3 and Comparative Examples 11 to 14 are shown in Table 7 below. .

Example 3, in which the spherical powders were properly mixed, showed the properties of being easy to apply, did not smear after drying, and did not cause stickiness around the eyes, showing the best feeling of use. Comparative Example 11 minimizes smearing and stickiness, and it was confirmed that the viscosity was low because spherical powder serving as a water-insoluble thickener was not incorporated, and stickiness and smearing around the eyes occurred after the contents were dried. Comparative Example 14 had a high content of spherical powder, so it had a very high viscosity, and it was applied thickly, so the drying rate was slow, it was not uniformly applied, and it was confirmed that smearing easily occurred.

Therefore, the total content of the spherical powder affecting the smearing and stickiness around the eyes is preferably 2.0 to 15% by weight, specifically 3 to 7% by weight.

Experimental Example 5: Sensory evaluation of the effect of use

The overall feeling of using the eyeliner was evaluated, such as blackness, smearing (persistence), powder flying, artificial eyelash adhesion, and stickiness around the eyes, and the results are shown in Table 9.

In the case of eyeliner, it should have high water resistance and durability, have an appropriate drying speed when applied, and have features that are easy to correct for makeup. In addition, by using a film former and volatile oil in an appropriate mixing ratio, it should last for a long time without causing eye irritation, powder flying, or smearing. The composition of the present invention having these characteristics is an eyeliner designed to attach artificial eyelashes, is magnetic, and has adhesion, and it was confirmed that Example 3 exhibits an overall excellent feeling of use.

Experimental Example 6: Comparison of the effects of using a water-dispersion type eyeliner and the oil-dispersion type eyeliner of the present invention

The effect of using an oil-dispersion type eyeliner (2) prepared according to the composition of Example 3 and a commercially available water-dispersion type eyeliner (1) was compared and tested.

As a result, as shown in FIG. 2 , in the case of the oil-dispersion type eyeliner of the present invention, it was confirmed that the oil-dispersion type eyeliner was applied uniformly and the drying rate was faster than that of the water-dispersion type eyeliner when applied once. In addition, it was confirmed that the oil-dispersion type eyeliner of the present invention is maintained without being torn off even if it is detached compared to the water-dispersion type eyeliner. In addition, as a result of evaluating the water resistance and durability of the two types of eyeliner, it was found that, unlike the water-dispersion type eyeliner, the oil-dispersion type eyeliner of the present invention is not easily erased by water, and it is not easily erased even after attaching and detaching the eyelashes several times or by hand. Confirmed.
