Description

[0001] The present invention relates to an eye-shadow cosmetic composition using a cross-linking polymer,

The present invention relates to an eye shadow cosmetic composition which is improved in pearl feel, durability and discomfort by using an ester-based oil, a polymer oil and a silica-based powder, and is imparted with elastic properties by using a crosslinked polymer.

So far, the eye shadow is divided into powder type or cream type. In the case of powder type shadow, general powder and pear content are about 80% and oil content is about 20%. In case of cream type, W / O formulation or oil We use emulsion binder, oil and powder as dispersing type. In general powder eyeshadow, coloring power is excellent and various feeling can be produced, but there is a limitation of pearl content and there is a limit in the sustainability. In addition, although the cream eye shadow has a strong durability and can be used as a bass function, there is a difficulty in using the cream eye shadow because the eye shadow is gathered on the wrinkles such as twin lines and the like. In the case of viscous shadows similar to the cream type eye shadow, the elastomer is used in a dispersed manner. However, there is a problem in securing a high pearl feeling because it is specific to the feeling and has a strong persistence but shows a blemish like a cream type.

As the recent trend is leading to high purity and sustainability, there is an increasing interest in eye shadow, which has a high purity and sustainability. Therefore, even though its own company or other companies are trying to release products suitable for them, And there is a limit to the oil content. The development of powder and oil binders for gel-type eye shadow that satisfies customers 'needs without sacrificing stability, high purity and long-lasting formability as it is difficult to satisfy customers' needs is currently under development. Is required.

The inventors of the present invention have conducted intensive studies to solve the above problems and have conducted experiments with various oil types (hydrocarbon, silicone, ester, mineral, etc.) and new powders (silica, nylon, etc.) As a result, when the ester oil, the polymer oil and the silica - based powder were used, the pearl contents and the sustainability of the contents were improved, and the erosion phenomenon was hardly observed. Even when the drop test was carried out, the formulation stability was secured.

Accordingly, it is an object of the present invention to provide an eye shadow cosmetic composition which provides a high pearl feeling, at the same time, has an improved durability and minimizes discomfort.

In order to achieve the above object, the present invention provides a gel type eye shadow containing an ester oil, a polymer oil, a crosslinked polymer powder and a crosslinked polymer oil.

The ester oil is distearate or tristearate, the polymer oil is styrene-isoprene copolymer, the crosslinked polymer powder is dimethicone, vinyl dimethicone cross polymer / Silica powder, and the crosslinked polymer oil is dimethicone / dimethicone. Vinyl dimethicone cross polymer oil.

The cosmetic composition provided by the present invention is stable in formulation even with a high content of pearl by using an ester oil and a polymer oil, imparts elastic properties to a formulation by using a crosslinking polymer, and provides a feeling of soft feeling by using a coated crosslinked polymer While reducing the malaise phenomenon.

The present invention provides an eye shadow cosmetic composition containing a high-puff using an ester-based oil, a polymer oil, a crosslinked polymer powder and a crosslinked polymer oil.

In the cosmetic composition of the present invention, an ester oil or a polymer oil is used as an oil binder, distearate or tristearate may be used as the ester oil, and the polymer oil may be a styrene-isoprene copolymer (styrene-isoprene copolymer) can be used.

When the ester oil is used as the oil binder, the polarity of the ester oil plays a role of enhancing the formulation stability between the powder and the nonpolar organic oil and the polymer, thereby securing the formulation stability. In order to ensure hardness and drop stability while using high-puff, the composition of the present invention uses an ester-based oil in an amount of 10 to 20% by weight based on the total weight of the composition. This content ratio is a proper amount in a molding range except for the powder and crosslinked polymer oil content.

The polymer oil used in the present invention is a high viscosity gel type and has a viscosity of 15,000-30,000 cps (10tr / min), which contributes to the moldability of the formulation. Ester oil and lipophilic substances. It also exhibits hydrophobicity and thus contributes to the improvement of durability. The composition of the present invention uses 5 to 10% by weight of a polymer oil based on the total weight of the composition. This content ratio is an appropriate range of content for obtaining the formulation characteristics of the powder and oil mixture.

The formulation of the composition of the present invention implements an elastic gel type. A crosslinked polymer powder and a crosslinked polymer oil are used to impart elasticity to the composition.

Dimethicone.vinyl dimethicone crosspolymer / silica powder is used as the crosslinked polymer powder. The crosslinked polymer powder is used in an amount of about 2.5 to 3% by weight based on the total weight of the composition, and the particle size of the crosslinked polymer powder has a distribution of 1 to 10 탆. The dimethicone.vinyl dimethicone crosspolymer / silica powder is a crosslinked polymer in which dimethicone.vinyl dimethicone cross polymer powder is coated with dimethicone.vinyl dimethicone cross polymer / silica powder in an amount of 3 to 4% by weight of silica It is powder. Dimethicone.vinyl dimethicone crosspolymer powder is viscous as the powder dissolves in the oil due to the viscosity of the polymer and imparts the elastic property to the molded article. In addition, the use of the coated crosslinked polymer powder can be used for manufacturing without the roll-mill treatment in the state of powdery state because there is no aggregation of the polymer, and it provides a feeling of soft feeling and spreads thinly compared with the general silicone crosslinked polymer, have.

The crosslinked polymer oil used is dimethicone / dimethicone / vinyl dimethicone cross polymer oil, and is used in an amount of about 14 to 15% by weight based on the total weight of the composition. Dimethicone / Dimethicone Vinyl Dimethicone Crosspolymer Crosslinked polymer oils have a gradual effect and impart elastic properties to formulations. Because this formulation is injection-molded, a certain amount of oil content must be secured, and it is difficult to impart elastic properties to the crosslinked polymer powder alone. Therefore, a crosslinked polymer oil is used together. However, if the oil is used alone, the content of the oil in the composition becomes too high and the feeling of use becomes worse.

The content of the oil (ester oil, polymer oil and crosslinked polymer oil) and the powder (all the powder including the crosslinked polymer powder) used in the present invention is preferably about 45 to 50:55 to 50 by weight. The higher the oil content, the better the durability of the cosmetic composition. However, since there is less friction on the eyelid at the time of application, the movement of the contents is facilitated. Therefore, the present invention is less prone to oily feeling compared to a general cream type eye shadow, which is an oil dispersion type or an emulsion dispersion type. On the other hand, if the oil content is too small, injection molding is difficult, and there is a problem that the molded product is cracked.

Since the composition of the present invention is a gel type, the time required for turning the contents into the Hans mixer is shorter than that of the general powder type composition in terms of the production method. Therefore, it is easy to express the high pearlness. .

The pearl used in the present invention is not limited to mica / titanium dioxide, mica / iron oxide / titanium dioxide, borosilicate, and the like.

The composition of the present invention may further contain additives such as powders and fragrances commonly used in the production of eye shadow in addition to the above components.

Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited thereto.

[Test example] Product evaluation

The compositions of Examples 1 to 2 and Comparative Examples 1 to 3 thus prepared were compared and evaluated for consistency, biaxiality, elasticity and drop test. The results are shown in Table 5.

Persistence Shabby Shout Drop test Example 1 5 4 5 4.5 Example 2 5 3 5 3.5 Comparative Example 1 5 2 2 5 Comparative Example 2 2 5 One 2 Comparative Example 3 3 One 4 One

5: very good, 4: slightly better, 3: moderate, 2: slightly poor, 1: very poor

The results are shown in Table 5 below. Compared with Comparative Example 1 using the crosslinked polymer powder and the crosslinked polymer oil in Examples 1 and 2, there is less ooze and the elasticity is excellent. In addition, there is a problem in that formulation stability is lowered when containing high-puff, but it can be seen that the formulation stability in the case of Examples 1 and 2 is close to that of Comparative Example 1.

Comparing Examples 1 and 2 with Comparative Examples 2 and 3 containing high-puffs, Comparative Example 2 is low in osmosis because it is a powder type, but it is evaluated poorly in terms of durability, elasticity, and formulation stability. In Comparative Example 3 in which the oil used was different, the persistence was normal and the elasticity was good, but the oozing phenomenon and the formulation stability were evaluated to be very bad. That is, when the high-puff is contained in the conventional formulation, the overall feeling of use of the product is not good, and the formulation stability can not be secured in particular. On the other hand, Examples 1 and 2 of the present invention have high scores on durability, discomfort, and elasticity, and thus, overall feeling of use is excellent and formulation stability is secured.

Accordingly, it is possible to provide an eye shadow cosmetic composition which is excellent in durability, improves oyster phenomenon, imparts elastic properties, and secures formulation stability by appropriately combining the content ratio of crosslinked polymer powder and oil, the content ratio of distearoyl oil, Can be provided.
