Description

WATER-IN-OIL TYPE MAKE-UP COSMETIC COMPOSITION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up cosmetic composition for in-water type, and more particularly to a make-up cosmetic composition for in-water type containing ultrafine particle carbon black powder and ultrafine lipophilic organic powder.

In recent years, as women's social activities and outdoor activities have increased, the desire for make-up persistence has increased significantly. The mascara's durability means that the mascara is not erased even after a certain period of time after it is applied to the eyelashes, and it does not come out to the skin. Many waterproof type water-based mascaras that give water sustainability have been introduced. However, such a mascara is generally excellent in waterproof effect, but oil resistance which is resistant to oil is insufficient, so that after the time of makeup, mascara may bounce under the eyes due to sebum.

So far, many methods have been developed for imparting a sustaining power to mascara. Basically, based on the oil-in-water emulsification formulation or oil-dispersion formulation having excellent water-repellent effect by the continuous oil phase, It has been common to use a large amount of an oil-soluble polymer which forms a film to increase the effect of persistence on water.

Particularly, the oil-soluble polymer is often used in mascara because it can easily increase its durability with an increase in the content. In recent years, a polyethylene solidified powder or a wax with a silicone group may be used in addition to the oil-soluble polymer. As an example thereof, Korean Patent Registration No. 10-0854086 discloses an eye make-up composition containing a silicone-added wax. However, the oil-soluble polymer has a disadvantage in that persistence to water is excellent, but persistence to sebum is poor. In recent years, dimethicone gum or trimethylsiloxysilicate, which is a silicon type, has been used to supplement the persistence of sebum. However, these raw materials are sticky to use, and the formed film is too hard to cause the powder to fall off. In Korean Patent Registration No. 10-0854086, a powder coated with a silicone resin used as a film forming agent is also used. In this case, however, the oil resistance is improved but the drawability is lowered.

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. 10-0854086

In order to solve the above-mentioned problems, the present invention includes a carbon black powder and a lipophilic powder, which are ultrafine particles and do not contain a separate surfactant, so that the particles of the carbon black and the lipophilic powder are stable at the interface between the water phase and the oil phase It is an object of the present invention to provide a makeup cosmetic composition in a water-in-oil type which can simultaneously perform a role as an interfacial stabilizer but also a coloring pigment and has excellent durability in both water and sebum, .

In order to solve the above-mentioned problems, the present invention provides a make-up cosmetic composition for in-water type 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 mu m.

In one embodiment of the present invention, the lipophilic powder is selected from the group consisting of silica, hectorite, bentonite, carbon black coated with oleophilic components, polystyrene, polytetrafluoroethylene, stearalkonium hectorite, quaternium-18 hectorite And distearammonium hectorite.

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

In one embodiment of the present invention, the carbon black powder and the lipophilic 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 and the lipophilic powder may be 1: 5 to 5: 1.

According to the in-water type makeup cosmetic composition of the present invention, it is possible to provide a makeup cosmetic composition which is excellent in stability in water-in-oil type formulation without containing any additional surfactant, excellent in both water and oil (water resistance and oil resistance) The emulsion formulation has a large size of emulsified particles, so that it is gently applied at the time of application, so that 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 a water-in-oil type makeup cosmetic composition containing carbon black and a lipophilic powder. Specifically, the present invention relates to a cosmetic composition, wherein the cosmetic composition is a water-in-oil type comprising trauma and internal phase, and the composition contains ultrafine particle carbon black powder and ultrafine lipophilic organic powder.

Common water-in-oil 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, a water-in-oil type formulation by pickling emulsification technology is provided, whereby a water-in-oil type composition containing no additional surfactant can be provided. The carbon black powder having a high hydrophilicity is located close to the inner phase of the water-in-oil emulsified formulation, and the lipophilic powder is used together with the oil-in-water type powder so as to be positioned close to the outer surface of the water-in-water type formulation. It is characterized by the excellent persistence of both water and sebum by the absence of a surfactant.

In the present invention, the lipophilic powder is selected from the group consisting of silica, hectorite, bentonite, carbon black coated with oleophilic components, polystyrene, polytetrafluoroethylene, stearalkonium hectorite, quaternium-18 hectorite and distearammonium hectorite , But the present invention is not limited thereto.

The carbon black coated with the lipophilic component may be coated with at least one 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 ultrafine particles, and preferably have a particle size of 0.0001 to 1 mu m, more preferably 0.5 mu m or less. This is because powder having a particle size of more than 1 탆 can not function as a formulation stabilizing agent because the interface between the water-in-oil type formulation can not be made 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.

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 the carbon black powder is less than 1: 5, the stability of the formulation is deteriorated. When the ratio of the carbon black powder is more than 5: 1, the oil-in-water emulsified form may not be stably formed, and the viscosity of the composition may become high, There is a problem in that the sustainability of the system 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, the ultrafine particle powder means both powder mixed with the carbon black powder and the lipophilic powder. The water-in-oil type formulation means that the traumatic phase is oily, the inner phase is aqueous phase, and the internal phase is aqueous 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 and the lipophilic powder used in the present invention are generally applied to conventional water-in-oil emulsions. The existing water-in-oil emulsion formulations necessarily contain a surfactant for the stabilization of the formulation. The carbon black used at this time and the carbon black coated with the lipophilic component are predominantly used as pigments for coloring the composition, , Hectorite, bentonite, polystyrene, polytetrafluoroethylene, stearalkonium hectorite, quaternium-18 hectorite, distearonium hectorite and the like play a major role as viscosity control agents for 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 lipophilic powder act as stabilizers for formulations, and the role and effect of the constituents are completely different from those of conventional compositions . In the Pickering emulsification technology, ultrafine particle powder can serve as an interface stabilizer because the ultrafine particle powder can be stabilized by placing it close to the inner or near outer surface based on the hydrophilic or hydrophobic characteristics of the powder to be. However, a formulation using a tool, such as a mascara brush formulation, has a greater force applied to the composition by a tool than a conventional makeup cosmetic composition, so that the stability of the formulation can be maintained during use even though the interface of the formulation is harder. In addition, oriental women have a much higher requirement for persistence such as blurring and falling powder compared to western women due to the shape characteristics of eyebrows, so that carbon black, which acts as a pigment, is positioned at the interface near the inner edge, At the same time, the lipophilic powder is used together with the interface near the trauma to form a double interface film, whereby a water-in-oil type composition having improved stability of the formulation can be obtained.

The water-in-oil type make-up cosmetic composition of the present invention is excellent in water-in-oil type stability and water resistance, and does not contain a surfactant having a hydrophilic group and a lipophilic group. Carbon black and lipophilic powder as ultrafine particles form a uniform film It is excellent in 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.
