Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an underwater type make-up cosmetic composition,

The present invention relates to an underwater type makeup cosmetic composition, and more particularly to an underwater type makeup cosmetic composition containing carbon black powder coated with a lipophilic component which is ultrafine particles and ultrafine particle hydrophilic powder.

In recent years, as women's social activities and outdoor activities have increased, the desire for make-up persistence has increased significantly. Mascara's persistence refers to the fact that the mascara is not wiped off or washed out even after a certain amount of time has been applied to the eyelashes, and many waterproof type mascaras have been introduced that give water sustainability in general. However, the mascara of the water-in-oil type emulsion has a disadvantage in that it is weak in imparting functions such as volume and curling power, which are fundamental properties of the mascara as compared with the persistence effect. Therefore, most of the technology development related to the mascara composition is based on the oil-in-water emulsified formulation and is made to improve the sustainability.

Until now, it has been common practice to improve the persistence of the oil-in-water emulsion type mascara composition by using a large amount of various film-forming polymers on the aqueous phase component of the continuous phase or by coating the surface of the coloring matter with the eyelashes. As an example, Korean Patent Laid-Open Publication No. 2009-0056396 discloses a mascara composition containing a powder coated with a cationic polymer and a cationic polymer. However, the film-forming polymer has an excellent effect of improving the sustainability, but has a disadvantage in that the viscosity of the film-forming polymer is rapidly increased upon contact with the air, thereby increasing the viscosity of the film-forming polymer.

In recent years, not only persistence of makeup but also customer demand for softness during use has become very important, so that a technique for simultaneously satisfying not only makeup persistence for water and sebum but also softening ability is needed more.

Korean Patent Publication No. 2009-0056396

In order to solve the above-mentioned problems, the present invention includes carbon black powder coated with a lipophilic component, which is an ultrafine particle, without containing any surfactant, and ultrafine particle hydrophilic powder, Makeup cosmetic composition which can stably exist at the interface of oil phase and serves not only as an interface stabilizer but also can function as a coloring pigment at the same time and has excellent durability in both water and sebum, And the like.

In order to solve the above-mentioned problems, the present invention provides an underwater type makeup cosmetic composition containing carbon black coated with a lipophilic component and a hydrophilic powder.

In one embodiment of the present invention, the carbon black powder coated with the lipophilic component and the hydrophilic powder may have a particle size of 0.0001 to 1 mu m.

In one embodiment of the present invention, the hydrophilic powder may be at least one selected from the group consisting of silica, barium sulfate, calcium carbonate, titanium dioxide, cellulose, nylon, alumina, talc and carbon black.

In one embodiment of the present invention, the carbon black coated with the lipophilic material may be coated with at least one of oil and wax.

In one embodiment of the present invention, the carbon black powder coated with the lipophilic component and the hydrophilic powder may be contained in an amount of 0.1 to 30% by weight based on the total weight of the inner phase of the composition.

In one embodiment of the present invention, the mixing ratio of the carbon black powder coated with the lipophilic component and the hydrophilic powder may be 1: 5 to 5: 1.

According to the underwater type makeup cosmetic composition of the present invention, excellent stability in water type formulation stability without containing any surfactant, excellent ballroom power, curling power and make-up persistence, and an emulsified formulation finished with ultrafine powder particles, Since the particle size is large, it is applied very smoothly when applied, so it is possible to produce natural lashes in desired shape.

Hereinafter, preferred embodiments of the present invention will be described in detail in order to facilitate the present invention by those skilled in the art.

The present invention provides an underwater type makeup cosmetic composition containing a carbon black coated with a lipophilic component and a hydrophilic powder. Specifically, the present invention relates to a cosmetic composition, wherein the cosmetic composition is an underwater type comprising trauma and internal phase, and the composition contains carbon black powder coated with lipophilic component which is ultrafine particles, and ultrafine particle hydrophilic powder.

Common underwater type compositions stabilize the interface between monomer and solvent using emulsifiers or surfactants. On the other hand, when inorganic particles are used instead of surfactants to stabilize the interface, this is called pickering emulsion. In the present invention, an oil-in-water type formulation by pickling emulsification technology is provided, thereby providing an underwater type composition containing no additional surfactant. The carbon black powder coated with a lipophilic component having a strong oleophilic property is placed close to the inner phase of the oil-in-water emulsified formulation and the hydrophilic powder is used together with the powder to be close to the trauma of the underwater type formulation so that the oil- It plays a role. It is characterized by the excellent persistence of both water and sebum by the absence of a surfactant.

The carbon black coated with the lipophilic substance may be coated with at least one of oil and wax. For example, the lipophilic material may be triethoxycaprylylsilane, but is not limited thereto.

In the present invention, the hydrophilic powder may be at least one selected from the group consisting of silica, barium sulfate, calcium carbonate, titanium dioxide, cellulose, nylon, alumina, talc and carbon black.

In the present invention, the carbon black coated with the lipophilic substance and the hydrophilic powder are ultrafine particles, preferably having a particle size of 0.0001 to 1 mu m, more preferably 0.5 mu m or less. Powders having a particle size exceeding 1 mu m can not function as a formulation stabilizer because they can not make the interface of the underwater type formulation hard because of the large gap between the particles. The powder having a particle size of less than 0.0001 탆 is rather difficult to uniformly exist at the interface because the cohesive force is so large that the powder is aggregated, which may hinder the stabilization of the formulation. Due to the characteristics of such ultrafine powder, the composition of the present invention is very smooth. By coating carbon black which is originally hydrophilic with an oleophilic material, it becomes lipophilic.

In the present invention, the mixing ratio of the carbon black coated with the lipophilic substance and the hydrophilic powder may be 1: 5 to 5: 1. If the ratio of the carbon black powder coated with the lipophilic substance is less than 1: 5, the stability of the formulation deteriorates. If the ratio is more than 5: 1, the oil-in-water emulsion may not be stably prepared, There is a problem that not only the water is stiff but also the persistence of water is lowered.

In the present invention, the ultrafine particle powder may be contained in an amount of 0.1 to 30% by weight, more preferably 5 to 15% by weight, based on the total weight of the internal phase of the composition. In the present invention, ultrafine particle powder means both powder of carbon black coated with lipophilic material and powder mixed with hydrophilic powder. The oil-in-water type formulation means that the traumatic phase is an aqueous phase, the inner phase is an oil phase, and the inner phase is an oil phase. If the total content of the ultrafine particle powders is less than 0.1% by weight, the effect of stabilizing the formulation hardly appears. If the total content exceeds 30% by weight, the effect of increasing the viscosity is so large that it becomes difficult to use it as an eye makeup especially as a mascara.

The carbon black coated with the lipophilic substance and the hydrophilic powder used in the present invention are generally applied to conventional oil-in-water emulsions. Conventional oil-in-water emulsion formulations necessarily contain a surfactant for the stabilization of formulations. The carbon black used at this time and the carbon black coated with the lipophilic substance are predominantly used as a coloring matter showing the color of the composition, , Barium sulfate, calcium carbonate, titanium dioxide, cellulose, nylon, alumina, talc and the like are mainly used for increasing the viscosity and viscosity of the composition and increasing the volume of the composition. On the other hand, the water-in-oil type composition of the present invention does not contain any surfactant, and carbon black and the hydrophilic powder serve as stabilizers of the formulations, and the role and effect of the components are completely different from those of the conventional composition. The reason why ultrafine particle powder can serve as an interface stabilizer in pickling emulsification technology is that the stabilization of the formulation can be realized by placing the ultrafine particle powder close to the internal or external surface based on the hydrophilic or hydrophobic characteristics of the powder. However, the use of a tool, such as a mascara brush or a formulator, compared to applying a makeup cosmetic composition in general, has a stronger force applied to the composition by the tool, so that the interface of the formulation is harder and stability can be maintained even during use. Oriental women are also much more demanding for persistence, such as bleeding and dropping powder, compared to Western women due to the shape of their eyebrows, so that the lipophilic coated carbon black, which acts as a pigment, is positioned at the near- And at the same time, the hydrophilic powder is used together with the interface near the trauma to form a double interface film, whereby a composition of an underwater type having improved stability of the formulation can be obtained.

The underwater type makeup cosmetic composition of the present invention has excellent stability in water type formulation and is excellent in water resistance, and does not contain a surfactant having a hydrophilic group and a hydrophilic group. Carbon black and hydrophilic powder as ultrafine particles form a uniform film It has excellent oil resistance because it slows the wetting of sebum. In addition, since the particle size of the Pickering emulsion using the ultra-fine particles is larger than that of the emulsion containing the surfactant, the emulsion is more easily smoothed by rubbing and excellent in spreadability.

The eye makeup composition of the present invention may contain, in addition to the above-mentioned effective ingredients, waxes, oils, powders, thickeners, pigments, film formers, nutrients, volatile solubilizers, antioxidants, (Hereinafter referred to as "other components") contained in a conventional eye makeup composition such as a cosmetic composition or the like.

In addition, the eye makeup composition of the present invention may be used in formulations including mascara, eye shadow, eyebrow pencil and eyeliner, preferably mascara or eyeliner, more preferably mascara, But is not limited thereto.

In addition, the composition of the present invention can be applied not only to eye makeup compositions but also to formulations such as lipsticks, lip gloss, foundation, and the like.

The present invention will be described in more detail through the following examples. However, the examples are for illustrating the present invention, and the scope of the present invention is not limited thereto.

In Comparative Examples 1 and 2, Components 4 to 7 are used as surfactants to stabilize the formulation, silica serves as a viscosity modifier and filler, and triethoxycaprylylsilane-coated carbon black serves as a pigment. Examples 1 to 9 show that Component 14 (lipophilic coated carbon black) and Components 15 to 23 (hydrophilic powder) serve as a formulation stabilizer without using any surfactant used in conventional oil-in-water emulsions, Ingredients 14 and 15 have a particular role as pigments. In the case where the ingredients 14 to 23 are not used, the formulations are made in Comparative Examples 1 and 2, and the viscosity is so thin that the usability is changed. However, Examples 1 to 9 can not be said to be compositions because the formulations themselves are not made.

The durability and oil resistance of each of the mascara compositions of Comparative Examples 1 and 2 and Examples 1 to 9 were tested using the following apparatuses.

<Water resistance test method>

1) Each composition was applied to a glass plate with a thickness of about 100 mu m using an applicator, and then completely dried.

2) After drying for 30 minutes, 1 ml of artificial tears was dropped.

3) After wetting for 10 minutes, the filter paper was placed on the roller, and the roller was pushed out and observed.

&Lt; Oil resistance test method >

1) Each composition was applied to a glass plate with a thickness of about 100 mu m using an applicator, and then completely dried.

2) After drying for 30 minutes, 1 ml of artificial sebum was dropped.

3) After wetting for 10 minutes, the filter paper was placed on the roller, and the roller was pushed out and observed.

As can be seen from Tables 5 and 6, it can be seen that Examples 1 to 9 exhibit excellent satisfaction not only in water resistance but also in oil resistance, as compared with Comparative Examples 1 and 2 which are conventional mascara compositions. This is because the example does not contain a surfactant having a hydrophilic group and a hydrophilic group, and also forms a uniform film on the surface to which ultra-fine particles such as carbon black and silica are applied, thereby slowing the wetting of artificial tears and sebum .

[Test Example 3]

The rubbing properties of the mascara compositions of Comparative Examples 1 and 2 and Examples 1 to 9 were tested by the following methods.

&Lt; Method of testability >

1) Each composition was applied to a glass plate with a thickness of about 100 mu m using an applicator, and then completely dried.

2) The state of the contents pushed out to the glass plate, that is, the length of the pushed out, was measured.

Each composition was repeated three times, and the average values thereof are shown in Tables 7 and 8 below. As the measured length was longer, the contents were smoothly slippery, and it was evaluated to be excellent in spreadability.

Item (cm) Comparative Example 1 Comparative Example 2 Example 1 Example 2 Example 3 Example 4 Length of push out 5 10 24 21 20 23
