Description

Water-in-oil makeup cosmetic composition {WATER-IN-OIL TYPE MAKE-UP COSMETIC COMPOSITION}

The present invention relates to a water-in-oil type makeup cosmetic composition, and more particularly to a water-in-oil type makeup cosmetic composition containing ultra-fine carbon black powder and ultra-fine particle lipophilic powder.

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, the mascara does not disappear or spread to the skin after a certain period of time. However, these mascaras are usually excellent in water resistance but lack oil resistance, which is resistant to oil, and may cause a phenomenon in which mascara spreads under the eyes by sebum after time of makeup.

Until now, many methods have been developed to give mascara a sustainability. Basically, it is based on water-in-oil emulsion formulations or oil-dispersion formulations having excellent water repellency effect by continuous oil phase components, and in order to increase the water repellency effect, It was common to use a large amount of oil-soluble polymers that dissolve in and form a film to enhance the sustaining effect on moisture.

Particularly, oil-soluble polymers are commonly used in mascara because they can easily be sustained with increasing content. Recently, in addition to oil-soluble polymers, polyethylene solidified powders or waxes with silicone groups are used. As an example, Korean Patent Publication No. 10-0854086 discloses an eye cosmetic composition containing a wax to which a silicone group is added. However, oil-soluble polymers have a disadvantage in that they are excellent in water resistance but poor in sebum. Recently, dimethicone gum or trimethylsiloxysilicate, which is a silicone type, is used to supplement the persistence on sebum, but these raw materials are easy to use, and the coating formed is too hard, causing powder to fall off. In Korean Patent Application Publication No. 10-0854086, a powder coated with a silicone resin used as a film forming agent was used. In this case, oil resistance is improved, but the drawback remains poor.

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. 10-0854086

In order to solve the above problems, the present invention does not contain a separate surfactant and contains carbon black powder and lipophilic powder which are ultrafine particles, so that the particles of the carbon black and lipophilic powder are stably at the interface between the aqueous phase and the oil phase. To provide a water-in-oil makeup cosmetic composition which is present and not only acts as an interfacial stabilizer, but also can serve as a color pigment, and has excellent durability in both water and sebum, and is very smooth in application. It is done.

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

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

In one embodiment of the present invention, the lipophilic powder is silica, hectorite, bentonite, carbon black coated with a lipophilic component, polystyrene, polytetrafluoroethylene, stearalconium hectorite, quaternium-18 hectorite And it may be one or more selected from the group consisting of disteadimonium hectorite.

In one embodiment of the invention, the lipophilic component in the carbon black coated with the lipophilic component may be one or more of oil and wax.

In one embodiment of the present invention, the carbon black powder and lipophilic powder may be contained 0.1 to 30% by weight based on 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 lipophilic powder may be 1: 5 to 5: 1.

According to the water-in-oil makeup cosmetic composition of the present invention, it is excellent in water-in-oil formulation stability without containing a separate surfactant, excellent durability in both water and sebum (water resistance and oil resistance), finished by ultra fine powder particles Emulsion formulations have a large size of the emulsified particles so that they are applied very smoothly upon application, thereby allowing natural appearance 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 a water-in-oil makeup cosmetic composition containing carbon black and a lipophilic powder. Specifically, the present invention in the cosmetic composition, the cosmetic composition is a water-in-oil type outer and inner phase, the composition is to contain ultrafine carbon black powder and ultrafine lipophilic powder.

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

In the present invention, the lipophilic powder is silica, hectorite, bentonite, carbon black coated with a lipophilic component, polystyrene, polytetrafluoroethylene, stearalconium hectorite, quaternium-18 hectorite and disteadimonium hectorite It may be one or more selected from the group consisting of, but is not limited thereto.

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

In the present invention, the carbon black and the lipophilic powder are ultra fine particles, and preferably have a particle size of 0.0001 to 1 μm, more preferably 0.5 μm or less. This is because powders having a particle size of more than 1 μm do not serve to stabilize the interface of the water-in-oil type formulation because of the large voids between the particles and thus do not serve 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.

In the present invention, the mixing ratio of the carbon black and the lipophilic powder may be 1: 5 to 5: 1. When the ratio of carbon black powder is less than 1: 5, the stability of the formulation becomes worse with time, and when it exceeds 5: 1, the water-in-oil emulsified formulation may not be made stable, and the viscosity of the composition becomes high, so that not only the stiffness and sebum are applied. There is a problem in that the persistence for.

In the present invention, the ultrafine particle powder may be contained in an amount of 0.1 to 30% by weight based on the total weight of the inner phase in the composition, and more preferably 5 to 15% by weight. In the present invention, the ultra fine powder refers to a powder in which carbon black powder and lipophilic powder are mixed. The water-in-oil formulation means that the external wound is an oil phase and the internal phase is an aqueous phase, which means an aqueous 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 viscosity increasing effect is so large that it is difficult to use especially for mascara for eye makeup.

Carbon black and lipophilic powder used in the present invention is a component that is generally applied to conventional water-in-oil emulsion formulations. Conventional water-in-oil emulsion formulations must contain a surfactant to stabilize the formulation, and the carbon black coated with the lipophilic component is mainly used as a pigment that represents the color of the composition, and also silica The lipophilic powders such as hectorite, bentonite, polystyrene, polytetrafluoroethylene, stearalconium hectorite, quaternium-18 hectorite and disteadimonium hectorite are mainly used as the viscosity modifier of the composition. On the other hand, the water-in-oil type composition of the present invention does not contain a separate surfactant, carbon black and lipophilic powder acts 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 can act as a stabilizer of the interface in the pickling emulsification technique is that the formulation can be stabilized by being located close to the inner or close to the trauma based on the interface depending on the hydrophilicity or hydrophobicity of the ultrafine powder. to be. However, formulations using tools, such as mascara brush formulations, have a greater force applied to the composition by the tools than when applying general makeup cosmetics, so that the interface of the formulation is harder to maintain stability even 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, so that carbon black, which serves as a pigment, is placed at the interface close to the inner phase to minimize pigment bleeding. At the same time, at the interface close to the outer phase, a lipophilic powder can be used together to form a double interface membrane, thereby obtaining a water-in-oil type composition having improved stability of the formulation.

The water-in-oil makeup cosmetic composition of the present invention is excellent in water-in-oil type 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 lipophilic powder form a uniform film without any gaps. The oil resistance is excellent because it slows down the wetting of sebum. 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.
