Description

OIL-IN-WATER TYPE MAKE-UP COSMETIC COMPOSITION}

The present invention relates to an oil-in-water makeup cosmetic composition, and more particularly to an oil-in-water makeup cosmetic composition containing a carbon black powder and an ultra-fine hydrophilic powder coated with a lipophilic component that is ultra-fine particles.

In recent years, the number of women's social and outdoor activities has increased the desire for the persistence of makeup. Mascara's persistence refers to the fact that after mascara is applied to the eyelashes, it does not clear or spread to the skin after a certain period of time. However, the mascara of the water-in-oil emulsion formulation has a disadvantage in that the provision of functions such as volume and curling power, which are basic properties as mascara, are weak compared to the sustaining effect. Therefore, most of the technical development related to the mascara composition is made in the direction of improving the sustainability based on oil-in-water emulsion formulation.

Until now, the research direction for improving the sustainability in mascara compositions of oil-in-water emulsion formulations has generally been to improve adhesion to eyelashes by using a large amount of various film-forming polymers in a continuous water phase component or coating the surface of a pigment. As an example, Korean Patent Laid-Open Publication No. 2009-0056396 discloses a mascara composition containing a cationic polymer and powder coated with a cationic polymer. However, the film-forming polymer is excellent in improving the sustainability, but has a disadvantage in that it dries quickly by increasing the viscosity because it dries quickly upon contact with air.

Recently, customer demand for not only the lasting makeup but also soft applicability during use is very important, and thus, a technology for satisfying not only the lasting makeup for water and sebum but also soft applicability is needed.

Republic of Korea Patent Publication No. 2009-0056396

In order to solve the problems described above, the present invention contains a carbon black powder and an ultrafine hydrophilic powder coated with a lipophilic component which is an ultrafine particle without containing a separate surfactant, so that the particles of the coated carbon black and the hydrophilic powder The oil-in-water makeup cosmetic composition that is stably present at the interface of the oil phase and not only functions as an interfacial stabilizer but also serves as a color pigment, and has excellent sustainability in both water and sebum, and is very smooth in application. To provide that purpose.

In order to solve the above object, the present invention provides an oil-in-water makeup cosmetic composition containing carbon black and a hydrophilic powder coated with a lipophilic component.

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

In one embodiment of the present invention, the hydrophilic powder may be one or more 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 one or more of oil and wax.

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

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

According to the oil-in-water makeup cosmetic composition of the present invention, it is excellent in oil-in-water formulation stability without containing a separate surfactant, excellent ballroom power, curling power and makeup persistence, the emulsion formulation is completed by ultra-fine powder particles emulsified Because of the large size of the particles, they are applied very smoothly when applied, allowing for natural look in the form of the desired eyelashes.

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 oil-in-water makeup cosmetic composition containing carbon black and a hydrophilic powder coated with a lipophilic component. Specifically, the present invention in the cosmetic composition, the cosmetic composition is an oil-in-water type consisting of an outer wound and an inner wound, the composition is to contain a carbon black powder and an ultrafine hydrophilic powder coated with a lipophilic component of ultrafine particles.

Common oil-in-water compositions use emulsifiers or surfactants to stabilize the interface between monomers and solvents. On the contrary, when stabilizing the interface using inorganic particles instead of surfactants, this is called pickering emulsification. The present invention provides an oil-in-water formulation by the pickling emulsification technique, thereby providing an oil-in-water composition that does not contain a separate surfactant. The carbon black powder coated with the lipophilic lipophilic component is located close to the inner phase of the oil-in-water emulsion formulation, and the hydrophilic powder is placed together close to the outer phase of the oil-in-water formulation to ensure that the emulsion formulation is stable without separation. Play a role. By including no surfactant, it is characterized by excellent durability for both water and sebum.

Carbon black coated with the lipophilic material may be coated with one or more of oil and wax. For example, the lipophilic substance may be triethoxycaprylylsilane, but is not limited thereto.

Hydrophilic powder in the present invention may be one or more selected from the group consisting of silica, barium sulfate, calcium carbonate, titanium dioxide, cellulose, nylon, alumina, talc and carbon black, but is not limited thereto.

In the present invention, the carbon black and the hydrophilic powder coated with the lipophilic material are ultra fine particles, preferably, have a particle size of 0.0001 to 1 μm, and more preferably 0.5 μm or less. This is because powders having a particle size of more than 1 μm do not make the interface of the oil-in-water formulation hard because of the large voids between the particles and thus do not act as a formulation stabilizer. Powders having a particle size of less than 0.0001 μm are rather large and cohesive, so that they are difficult to be uniformly present at the interface and thus may hinder the stabilization of the formulation. Due to the properties of these ultrafine particles, the composition of the present invention is very smooth. The hydrophilic carbon black is coated with a lipophilic material to make it lipophilic.

In the present invention, the mixing ratio of the carbon black and the hydrophilic powder coated with the lipophilic material may be 1: 5 to 5: 1. If the ratio of the carbon black powder coated with lipophilic substance is less than 1: 5, the formulation will have poor stability over time, and if it exceeds 5: 1, the oil-in-water emulsion formulation may not be made stable, and the composition will have high viscosity. Not only is it stiff and there is a problem that the persistence of the water is lowered.

In the present invention, the ultrafine particle powder may be contained in an amount of 0.1 to 30% by weight, and more preferably 5 to 15% by weight, based on the total weight of the inner phase in the composition. In the present invention, the ultrafine particle powder refers to both a carbon black powder coated with a lipophilic material and a powder mixed with a hydrophilic powder. In oil-in-water formulations, the outer wound is an aqueous phase and the inner phase is an oil phase, which means an oil phase. When the total content of the ultra fine powder is less than 0.1% by weight, the effect of the formulation stabilization is hardly exhibited, and when it exceeds 30% by weight, the effect of increasing the viscosity is so large that it is difficult to use especially for mascara for eye makeup.

Carbon black and hydrophilic powder coated with a lipophilic material used in the present invention is a component generally applied to conventional oil-in-water emulsion formulations. Existing oil-in-water emulsion formulations must contain a surfactant to stabilize the formulation, and the carbon black and the carbon black coated with a lipophilic substance are mainly used as a pigment that indicates the color of the composition, and also silica Hydrophilic powders, such as barium sulfate, calcium carbonate, titanium dioxide, cellulose, nylon, alumina and talc, mainly play a role of improving the viscosity by increasing the viscosity modifier and coating amount of the composition. On the other hand, the oil-in-water composition of the present invention does not contain a separate surfactant, carbon black and hydrophilic powder to act as a stabilizer of the formulation, the role and effect of the components are completely different from the existing composition. The reason why the ultrafine powder may act as a stabilizer of the interface in the pickling emulsification technology is to stabilize the formulation by being located close to the inner or near the outer trauma based on the interface depending on the hydrophilicity or hydrophobicity of the ultrafine powder. However, the use of tools, such as mascara brushes, formulations, compared to normal makeup cosmetic application, the greater the force exerted on the composition by the tool, so that the interface of the formulation is harder to maintain stability during use. In addition, Asian women have much higher persistence requirements such as smearing and powdering than Western women because of the shape of their eyebrows. At the same time, by using a hydrophilic powder together at the interface close to the outer phase to form a double interfacial membrane can be obtained an oil-in-water composition with improved stability of the formulation.

The oil-in-water makeup cosmetic composition of the present invention is excellent in oil-in-water formulation stability and excellent in water resistance, and does not contain a surfactant having a hydrophilic group and a lipophilic group, and ultrafine particles of carbon black and a hydrophilic powder form a uniform membrane. Oil resistance is excellent because it slows down sebum wetting. In addition, since the particle size of the pickling emulsion formulations using ultra-fine particles is larger than that of the emulsion formulation containing the surfactant, it is more easily applied by rubbing, so that the spreadability is excellent.

The eye makeup composition of the present invention, in addition to the above active ingredients, within the range that does not impair the effects of the present invention, waxes, oils, powders, thickeners, pigments, film formers, nutrients, volatile solubilizers, antioxidants, preservatives and flavors And other components (hereinafter referred to as "other components") contained in conventional eye makeup compositions, and the like.

In addition, the eye makeup composition of the present invention can be used in formulations containing mascara, eyeshadow, eyebrow pencil and eyeliner, preferably mascara or eyeliner, more preferably mascara, but It is not limited.

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

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