Description

Eye makeup composition of clear liquid oil dispersion formulation

This application claims the benefit of priority based on Korean Patent Application No. 10-2015-0137389 filed on September 30, 2015, and includes all contents disclosed in the literature of that Korean patent application as part of this specification.

The present invention relates to an eye makeup composition of a liquid oil-dispersed formulation that can simultaneously realize transparency and viscosity.

Recently, as the climate changes at a high temperature and high humidity, there is an increasing demand for makeup products that have a lighter feeling and have a longer lasting durability. In the field of eye makeup cosmetics, such as mascara or eyeliner, in particular, there is an increasing demand for a product having excellent long-lasting, long lasting application state and no bleeding. One of the cosmetics that appeared to meet the need for such persistence is the 'top coat' formulation. The top coat adds a coating effect to existing mascara or eyeliner and improves the makeup's durability. In recent years, the top coat may be used as mascara itself or through a transparent mascara formulation to give only a curling effect without color to produce a lighter, more natural look.

Such topcoat formulations are required to have a transparent appearance so that the color of the right product or the feel of the applied area can be revealed as it is due to its use characteristics.

However, in the conventional general transparent topcoat products, most of the water-dispersion formulations were easily erased by sweat or tears, and thus the persistence was very unsatisfactory.

In order to solve the above-mentioned sustainability problem, a liquid dispersion having a high sustained liquid form was considered suitable, but in this case, there were many limitations due to the characteristics of the top coat formulation. Specifically, make-up products must form an appropriate level of viscosity, and when preparing the eye makeup composition with the liquid oil-dispersed formulation, it is difficult to simultaneously realize viscosity and transparency through oil thickeners generally used. There was. For example, when using a wax thickener that is white at room temperature as one of the typical oily thickeners, the formulation becomes opaque when the viscosity of the composition is appropriate. It fell off and was inconvenient to use.

Therefore, the development of the eye makeup composition that can realize the transparency and viscosity at the same time while having a high persistence is required.

Republic of Korea Patent No. 10-1221231, "Transparent oil-based cosmetic composition"

The inventors of the present invention have conducted various studies in order to solve the above-mentioned problems. As a result, in order to secure high durability, the eye makeup composition is prepared in a liquid oil-dispersion formulation. It was found that it is possible to provide an eye makeup composition that is transparent and has an appropriate viscosity.

Accordingly, it is an object of the present invention to provide an eye makeup composition capable of simultaneously implementing transparency and viscosity.

The present invention to achieve the above object

Contains volatile oils and thickeners,

The thickener provides an eye makeup composition of a liquid oil dispersion formulation, which is at least one thickener selected from the group consisting of amide-based polymers and dextrin palmitate / ethylhexanoate.

The present invention,

Volatile oils and thickeners, wherein the thickener is selected from the group consisting of amide based polymers and dextrin palmitate / ethylhexanoate, which is one or more thickeners selected from the group consisting of liquid oil dispersion formulations. An eye makeup composition is provided.

The eye makeup composition according to the present invention is a liquid oil-dispersion formulation that can be applied to eyebrows, eyelashes, etc., while having high sustainability, and simultaneously implementing transparency and proper viscosity suitable for use.

Thus, the most preferred application formulation of the eye makeup composition of the present invention may be a top coat formulation for eye makeup. 'Top coat' is a formulation that is applied over a mascara, brow or eye line to improve the durability and gloss, and to prevent bleeding and smearing, and thus transparency is essential. In addition, the eye makeup composition of the present invention can be applied to all eye makeup formulations that can utilize the same and similar effects of the present invention in addition to the top coat formulation, such as transparent mascara, brow, eyeliner, and the like without limitation.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated in detail. However, the following contents are described only for the most representative embodiments in order to help the understanding of the present invention, and the scope of the present invention is not limited thereto, and the present invention should be understood to cover all ranges equivalent to the following contents.

The present invention is characterized in that a specific type of thickener is used in order to simultaneously realize a transparent appearance and an appropriate viscosity when increasing while having affinity with volatile oil.

Specifically, the thickener of the present invention may be used alone or in combination of two or more thickeners selected from the group consisting of an amide polymer and dextrin palmitate / ethylhexanoate. do.

More preferably, the amide-based polymer thickener is bis-stearyl ethylenediamine / neopentyl glycol / stearyl hydrogenated dimer dilinoleate copolymer, and bis-stearyl ethylenediamine / neopentyl glycol and stearyl hydrogenated dimer dilinoleate copolymer. And / or Ethylenediamine / Hydrogenated Dimer Dilinoleate Copolymer Bis-Di-C14-18 Alkyl Amide can be used.

In contrast to the thickeners used in conventional eye makeup compositions, amide-based polymers have not typically been utilized as thickeners for eye makeup, especially mascara or topcoat formulations, and dextrin palmitate / ethylhexanoate has only viscosity control. While only used in combination with other conventional oil thickeners for the purpose, in the present invention, at least one mixture selected from the group consisting of the amide polymer and / or dextrin palmitate / ethylhexanoate is used as the thickener. By doing so, the appearance of the composition can be transparently formed, and at the same time, a suitable viscosity suitable for use can be realized.

The total content of the thickeners used in the present invention may depend on the amount of thickeners that may be conventionally added to prepare the eye makeup composition. Specifically, the content of the thickener may be 1 to 30% by weight, preferably 15 to 25% by weight, and more preferably 20% by weight, based on the total weight of the volatile oil. If the thickener is included in less than 1% by weight, the thickening effect is reduced to form a formulation that flows down like water, which may cause inconvenience in use, and when included in more than 30% by weight, an excessively sticky formulation may be formed.

The eye makeup composition of the present invention to which a specific thickener is added in the above range has a viscosity of 30,000 to 300,000 cps. At viscosity of less than 30,000 cps, it is unsuitable for use because it flows down like water, and at a viscosity of more than 300,000 cps, the composition is too stiff and difficult to apply to brows, eyelashes, etc., but in the present invention, an appropriate range of viscosities can be implemented to improve convenience. Preferably from 30,000 to 200,000cps, more preferably it can form a viscosity of about 100,000cps at 20% by weight, the optimum thickener content relative to the total weight of the volatile oil.

In this case, the most preferred viscosity range means the most suitable range to be utilized as a top coat formulation for mascara and the like. Since the viscosity of the mascara formulation is generally formed around 200,000 cps, the top coat applied thereto has a relatively lower viscosity to provide good applicability and usability.

However, the application example of the eye makeup composition of the present invention is not necessarily limited thereto, and may be appropriately adjusted and used to form the most suitable viscosity as necessary. For example, when it is desired to use as a formulation to be applied alone without any overcoat, such as transparent mascara or brow, it may be desirable to have a higher viscosity than the topcoat formulation, in this case a thickener that forms a relatively high viscosity You can choose the combination. In particular, the dextrin palmitate / ethylhexanoate compared to the amide polymer thickener tends to form a relatively high viscosity, it is also possible to adjust the viscosity to high. Even in this case, the viscosity of the composition does not exceed a maximum of 300,000 cps.

On the other hand, the conventional eye makeup composition includes a volatile oil for the purpose of drying quickly without smearing, the eye makeup composition of the present invention also includes a volatile oil.

Volatile oils having the highest compatibility with the specific thickeners described above include hydrocarbon-based volatile oils and / or silicon-based volatile oils. Preferably it may be in the form of including a hydrocarbon-based volatile oil and optionally further comprises a silicone-based volatile oil. In the case of silicone oil it is possible to secure the transparency of the composition, but because the tendency to increase less than the hydrocarbon-based oil.

As the hydrocarbon-based volatile oil, at least one selected from the group consisting of C8 to C16 branched aliphatic hydrocarbon oils, and C8 to C16 branched aliphatic ester oils may be used. More preferably, one or more substances selected from the group consisting of isodecane, isododecane and isohexadecane can be used as isoalkanes.

In addition, the silicone-based volatile oil of the present invention may use a linear or cyclic silicone oil, preferably a silicone oil having a viscosity of 6 cSt or less at 25 ° C. and having 2 to 5 silicon (Si) atoms. More preferably dimethicone, trisiloxane or mixtures thereof can be used.

Hereinafter, test examples to help understand the effects of the present invention are described. However, the following test examples correspond to only one test examples regarding the configuration and effects of the present invention, and the scope and effects of the present invention are not limited thereto.
