Cosmetic composition for eye cosmetics {Cosmetic Composition for eye makeup}

The present invention relates to a cosmetic composition for eye cosmetics comprising glutinous rice dough. More specifically, the present invention relates to a cosmetic composition for eye cosmetics that seeks to compensate for skin affinity, blackness, adhesion, curling, and volume, which are insufficient properties due to the decrease in dispersion due to the small size of carbon black, and insoluble starch containing amylopectin as a main component. The present invention relates to a cosmetic composition for eye cosmetics, which further comprises 0.1 to 80 wt% of phosphorus glutinous rice dough and 1 to 30 wt% of colored pigments and polyvinyl alcohol (polyvinyl alcohol).

The present invention relates to a cosmetic composition for eye cosmetics, and is a cosmetic composition comprising glutinous rice paste, PVA (Polyvinyl alcohol, polyvinyl alcohol) and colored pigments, which is a non-soluble starch mainly composed of amylopectin. The present invention shows an excellent volumetric function by increasing the adhesiveness by the gelatinization action of water and the present thickener (gluten rice dough) in the cosmetic composition for eye cosmetics. The present invention uses the glutinous rice dough, which is a natural material, in place of the existing slack type slimy cellulose-based synthetic polymer and the acrylic-based synthetic polymer to form a muddy and thin film. This improves the dispersibility of carbon black or iron oxide. As a result, the blackness is enhanced and the texture is developed to prevent the eye cosmetics from easily falling off the eyelashes. Therefore, it is possible to compensate for skin affinity, blackness, adhesion, curling, and volume, which are insufficient properties due to the decrease in dispersibility due to the small size of carbon black.

Generally mascara or eyeliner used for eye cosmetics is used to produce more clear eyes. In particular, the mascara is applied to the eyelashes to raise the eyelashes abundantly to make the eyes clear. The methods to make the eyes clear are to separate the strands by spreading them like a fan shape and to spread the contents around the one eyelash and to make the eyes clear by the thickness.

In addition, by curling from the root of the eyelashes to increase the length of the eyelashes visible outwards to make the eyes look larger, and by using the fibers listed long to make the eyelashes look cool by actually increasing the length of the eyelashes. Like this, mascara has three big attributes such as volume, curling, and long lash, and there are other ways of expressing deep colors by expressing colors deeply, and the ultimate purpose of all is to produce clear eyes.

The early mascara was a solid form of a mixture of sodium stearate and carbon black, which was applied using a brush soaked in water. However, over time, more convenient mascara has been required, and this has resulted in a type of mascara in which a brush is immersed in a container. In addition, a soft type of emulsified mascara was developed by improving the stiff feel of the existing solid mascara. Emulsified mascara is a form in which vegetable ester waxes or hydrocarbon waxes are mixed with emulsified polymers having high plasticity and high safety. Emulsification type is largely oil / water (O / W) type and water / oil (W / O) or water / silicone (Water / Silicone, W / S) which has great persistence against water Can be subdivided into In addition, mascara, which is currently being developed, may be developed into a water dispersion or oil dispersion type in order to increase the pearly feeling, and these formulations use a top coat or a gorgeous pearl persimmon to enhance the eyelash oil or moisture persistence. It can also be used as a decorative mascara to give the eyelashes a sparkle. As such, mascara is divided into various formulations and functions.

As a prior art that can be compared with the present invention, Patent Registration No. 10-0520842 shows that mascara composition using starch powder does not easily come off from eyebrows, so that there is little eye irritation, and excellent adhesion persistence and long lash function. Naturally derived starch powder is patented as a claim item. The starch powder used therein is a patent claim for starch composed of amylose and amylopectin, the contents of which are too broad and comprehensive. In addition, by limiting the aspect ratio to 0.1 ~ 0.9, the logic of focusing on persistence is being laid out. However, this conventional technology facilitates dispersion of carbon black and iron oxide, which are difficult to disperse stability, ensures long-term stability, and when the product is applied to the product, the contents are easily transferred to the eyelashes so that excellent skin affinity, blackness, adhesion, curling power, There is not enough to show the volume.

In order to solve the above problems, the present inventors have studied the cosmetic composition for eye cosmetics having excellent skin affinity, blackness, adhesion, curling power, and volume, and it is difficult to disperse stability of carbon black and iron oxide when using glutinous rice dough derived from natural origin. The present invention has been accomplished by facilitating dispersion and ensuring long-term stability, thereby providing a composition that can be easily delivered to the eyelashes when applied to the product. It is therefore an object of the present invention to include the three main functions of mascara mentioned above, namely volume, curling and longlash, in particular volume and curling enhancement. In particular, by including a suitable amount of glutinous rice dough, a non-soluble starch containing amylopectin as a main component, the cosmetic composition for eye cosmetics that can compensate for skin affinity, blackness, adhesion and curling power, which are insufficient properties due to the decrease in dispersibility due to the small size of carbon black To provide.

Cosmetic composition for eye cosmetics according to the embodiments of the present invention, 0.1 to 80% by weight of any one or a mixture of glutinous rice dough or amylopectin or 1 to 30% by weight of the pigment pigment relative to the total weight of the cosmetic composition for eye cosmetics The glutinous rice dough may include any one or a mixture of glutinous rice and water or a polyol, and the colored pigment may include any one or a mixture of carbon black or iron oxide.

The cosmetic composition for eye cosmetics may further include polyvinyl alcohol (polyvinyl alcohol), the content may be 0.1 to 20% by weight relative to the total weight of the cosmetic composition for eye cosmetics.

The glutinous rice dough may include 0.1 to 50% by weight of glutinous rice and 0.1 to 90% by weight of water or polyol or a mixture thereof, based on the total weight of glutinous rice dough, and may be an aqueous base dough obtained after mixing with a homogenizer. .

The cosmetic composition for eye cosmetics may be any one of the oil-in-water emulsion type, water-in-oil type emulsion type, oil dispersion type or water dispersion type.

The cosmetic composition according to the present invention simultaneously contains glutinous rice dough as an active ingredient to simultaneously compensate for insufficient skin affinity, blackness, adhesion, curling power due to a decrease in dispersibility due to the small size of colored pigments such as carbon black, and enrich the eyelashes. It has the effect of making it look good. In addition, by further comprising PVA (Polyvinyl alcohol, polyvinyl alcohol) as an active ingredient to further improve the dispersion stability of the colored pigments and shows an innovatively excellent effect in terms of curling and volume effects.

Hereinafter, the present invention will be described in more detail with reference to the following examples. Objects and features of the present invention will be readily understood through the following examples. The present invention is not limited to the embodiments described herein, but may be embodied in other forms. The embodiments introduced herein are provided to sufficiently convey the spirit of the present invention to those skilled in the art. Therefore, the present invention should not be limited by the following examples.

Cosmetic composition for eye cosmetics according to embodiments of the present invention may include 0.1 to 80% by weight glutinous rice dough, which is a non-soluble starch containing amylopectin as a main component, and 1 to 30% by weight of colored pigments, based on the total weight of the cosmetic composition. . In addition, it may be a cosmetic composition for eye cosmetics further comprising 0.1 to 20% by weight of PVA (Polyvinyl alcohol, polyvinyl alcohol) in the raw material.

The cosmetic composition for eye cosmetics may include a glutinous rice paste and a color pigment added to the water base and may further include PVA (Polyvinyl alcohol, polyvinyl alcohol) in the raw material. The water base may be 0.5 to 60% by weight based on the total weight of the cosmetic composition. The water base may mean WATER PHASE (water phase, water phase) in which raw materials other than glutinous rice dough (gluten rice + water) or amylopectin and PVA (polyvinyl alcohol, polyvinyl alcohol) and pigments are available in water.

Glutinous rice (glutinous rice) used in the present invention is a word corresponding to non-glutinous rice, also called nami or spice. Normally, non-rice cooked rice is translucent, and the glutinous rice is milky opaque and can be distinguished. In addition, starch of glutinous rice is mostly composed of amylopectin, so it is clearly distinguished because the iodine reaction is reddish brown.

Amylopectin, the main component of the glutinous rice used in the present invention, is a tasteless, odorless white powder that is a kind of polysaccharide constituting the insoluble portion of the starch particles. Along with amylose, it is a major component of starch. It is a white powder with no taste or smell. It is insoluble in water but melts in hot water to form grass. Adding butanol to starch in hot water can separate amylopectin because only amylose precipitates. Adding iodine to an aqueous solution of amylopectin turns reddish purple, which is used to detect amylopectin. Amylopectin is found in higher plants. Rice wheat corn, potato, potato, banana, etc. contain 70-80% by weight amylopectin and 20-30% by weight amylose. However, glutinous rice mostly consists of amylopectin and contains little amylose.

The structure of amylopectin is based on a chain of 25-30 glucoses linked by α-1 and 4-bonds. The other chain is combined with one chain like a twig, and the other chain is combined with the branched chain again, and the branch has a complicated structure with many branches. Branching bonds are α-1, 6-bonds. Amylopectin is degraded by amylase or phosphorylase. However, normal amylase (α-, β-amylase) or phosphorylase does not break down the branching bonds, so there is a remaining part. The details of how amylopectin is synthesized in plants have not been elucidated, but it is clear that adenosine diphosphoglucose is involved.

In general cosmetic compositions for mascara, eyeliner, and the like, most of the aqueous substance is composed of a water-soluble component of hydroxyl ethyl cellulose (hydroxyl ethyl cellulose), xanthan gum, polyol, and the like. To provide a cosmetic composition for the eye cosmetics containing glutinous rice dough and PVA containing mainly processed insoluble starch to be used in mascara or eyeliner. The processing means a process of obtaining a more homogeneous glutinous rice dough using a 400MESH net after mixing the steamed glutinous rice and water (or polyol) with a homogenizer.

In the case of general cosmetic compositions for eye cosmetics such as mascara and eyeliner, in order to disperse carbon black or iron oxide, in the case of emulsion type, oil phase and water phase are separated and weighed, and carbon black and iron oxide are dispersed in a water phase through a homogenizer, Subsequently, the oil phase containing the surfactant is added to the aqueous phase and dispersed to complete the emulsification. At this time, the dispersibility of the carbon black in the water phase is significantly inferior due to the lack of water affinity of the particles and very small particles. This results in a phenomenon in which the carbon black aggregates easily in spite of forced dispersion.

However, the present invention solves the above problems and innovatively improved the ease of dispersion and dispersion stability. Cosmetic composition for eye cosmetics such as mascara and eyeliner using glutinous rice among the skin-friendly materials that can disperse the aqueous phase and improve the pigment dispersion and have structural closeness and volume function while increasing the pigment dispersion. Introduced.

In the case of the glutinous rice, depending on how the dough is made in water, it exhibits various physical properties such as scratching and adhesive strength. Using this property, glutinous rice, which is a natural material, was introduced by processing it into a dough state useful for eye cosmetics such as mascara or eyeliner. In particular, glutinous rice contains a large amount of amylopectin, which is remarkably insoluble unlike natural substances containing starch, and thus can be expected to have excellent effects in cosmetics for eye cosmetics.

In the present invention, the glutinous rice dough is 0.1 to 50% by weight of glutinous rice and 0.1 to 90% by weight of water or polyol in a steamed state at 100 to 160 ℃ for 20 to 40 minutes with respect to the total weight of the glutinous rice dough It is composed of a water-based dough obtained by using a 400MESH network for a more homogeneous mixture after mixing with a homogenizer. The content of the glutinous rice dough is preferably 0.1 to 80% by weight relative to the total weight of the cosmetic composition for eye cosmetics. If less than 0.1% by weight, the amount of amylopectin contained in the glutinous rice dough is not enough to give the colloidal properties, it is difficult to achieve the desired performance, if it exceeds 80% by weight pigment and film forming agent contained in the eye cosmetic composition Can inhibit blackness and film forming ability. In addition, instead of the glutinous rice dough, amylopectin may be used alone, or the glutinous rice dough and amylopectin may be mixed and used. However, as the amount of amylopectin used increases, the amount may be slightly reduced.

The colored pigment used in the present invention may be either carbon black or iron oxide, or a mixture thereof. The colored pigment is preferably 1 to 30% by weight based on the total weight of the cosmetic composition for eye cosmetics. When the colored pigment is used in less than 1% by weight, there may be a problem that it is difficult to obtain a color effect because the amount of the pigment is too small, on the contrary, if it exceeds 30% by weight, the viscosity is excessively increased so that the feeling of use is not good There may be a problem.

For the cosmetic composition for eye cosmetics to increase the desired blackness in the present invention, the particles of the colored pigment should be fine, and the fine particles should be dispersed stably. That is, the obstacles to the part where the pigment expresses color should be removed. As fine pigments, carbon black having a particle size of 20 to 50 nm is more preferable than black iron oxide having a thickness of about 300 nm, but considering the volume feeling by the pigment and dispersion stability by the glutinous rice dough Additional iron oxides may be introduced. The introduction of black iron oxide can increase the body feeling giving blackness and volume at the same time.

In the present invention, the PVA (polyvinyl alcohol, Polyvinyl alcohol) is a material that dissolves in water has a film-forming ability to attach to the eyebrows to enable the setting of the desired shape. It is excellent in dispersion stability by forming a colloidal liquid when dispersed in water. When mixed with glutinous rice dough or amylopectin used in the present invention will contribute to the improvement of colloidal properties, dispersibility and blackness. However, when used excessively, film drying speed becomes slow and water resistance becomes small, and it may impair a requirement as a cosmetics. The content of the PVA (Polyvinyl alcohol, polyvinyl alcohol) is preferably 0.1 to 20% by weight based on the total weight of the composition. If it is less than 0.1% by weight, it is difficult to form a film, and if it is more than 20% by weight, the film drying speed is slow and water resistance is low, which may impair the requirement as a cosmetic.

In the present invention, glutinous rice dough containing amylopectin and amylopectin itself play a large role in imparting colloidal stability in the dispersion stability of the pigment. As described above, polyvinyl alcohol (polyvinyl alcohol) is included together. The synergy effect is large and the curling and volume effects are also significant.

The cosmetic composition for eye cosmetics may be one having the properties of oil-in-water emulsion type, water-in-oil emulsion type, oil dispersion type or water dispersion type. It will be apparent to those skilled in the art that the preparation of oil-in-water emulsion, water-in-oil emulsion, oil dispersion type or water dispersion type cosmetics can be easily performed.

Glutinous rice dough, the composition included in the present invention is used in cosmetics for eye cosmetics such as mascara or eyeliner to improve the dispersibility and adhesion of the pigment, it is possible to improve the blackness, curling, volume and skin affinity. In addition to this, it can be widely used, including in other cosmetic compositions.

In addition, the conventional eyeliner composition mainly includes a thickener and a film forming agent, the conventional mascara may be made by further including an emulsifier and a wax component.

In addition, the composition and manufacturing method of such mascara and eyeliner is well known to those skilled in the art can be easily understood.
