Description

Transparent oil-dispersed fluid type cosmetic composition for eye make-up

The present invention relates to an eye makeup composition of a liquid oil dispersion formulation capable of simultaneously implementing transparency and viscosity.

Recently, as the climatic environment changes with high temperature and humidity, the makeup trend has become the key to light usability and durability. In particular, in the field of eye makeup cosmetics such as mascara or eyeliner, the need for long-lasting makeup without smearing and maintaining the first applied state for a long time is gradually increasing. One of the cosmetics that has appeared to satisfy this need for durability is a 'top coat' formulation. The top coat is applied over the existing mascara or eyeliner to give a coating effect and improve the durability of makeup. Also, in recent years, there are many cases in which the top coat is used as mascara itself or by giving only a curling effect without color through a transparent mascara formulation to produce a lighter and more natural-looking makeup.

Such a top coat formulation is required to have a transparent appearance so that the color of the first applied product or the feeling of the applied area can be revealed due to the nature of its use.

However, looking at conventional transparent topcoat products, most of the aqueous dispersion formulations were easily erased by sweat or tears, and thus the durability was very unsatisfactory.

In order to solve the above-mentioned persistence problem, it was thought that a liquid oil-dispersion formulation having high stickiness was suitable, but even in this case, there were many restrictions due to the characteristics of the top coat formulation. Specifically, make-up products must have an appropriate level of viscosity for use. In the case of preparing an eye makeup composition with the liquid oil dispersion formulation, it is difficult to simultaneously realize viscosity and transparency through commonly used oil phase thickeners. there was For example, in the case of using a white wax thickener at room temperature as one of the representative oil phase thickeners, the formulation becomes opaque when the viscosity of the composition is appropriate, and when the formulation is transparent, the viscosity is too low and flows down like water, resulting in adhesiveness. It fell and was inconvenient to use.

Therefore, it was necessary to develop an eye makeup composition that can simultaneously implement transparency and viscosity while having high durability.

Transparent oil-in-water cosmetic composition (Korea Patent No. 10-1221231)

The inventors of the present invention conducted various studies to solve the above-mentioned conventional problems. As a result, while preparing an eye makeup composition in a liquid oil dispersion formulation to ensure high persistence, when specific thickeners are used alone or in combination, It was confirmed that it is possible to provide an eye makeup composition that is transparent and has an appropriate viscosity.

Accordingly, an object of the present invention is to provide an eye makeup composition that can simultaneously implement transparency and viscosity.

In order to achieve the above object, the present invention

volatile oils and thickeners;

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

By using the above problem solving means, the eye makeup composition of the liquid oil dispersion formulation of the present invention can simultaneously implement transparency and a viscosity suitable for use.

Accordingly, the eye makeup composition of the present invention can reveal the color of the product applied as a base or the characteristics of the application site as it is, and can also be properly adhered to the area to be used.

The present invention is

A liquid oil dispersion formulation comprising a volatile oil and a thickener, wherein the thickener is at least one thickener selected from the group consisting of an amide-based polymer and dextrin palmitate/Ethylhexanoate. 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., and can simultaneously implement transparency and appropriate viscosity suitable for use while having high persistence.

Therefore, 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 used over mascara, brow or eyeliner to improve durability and gloss and prevent smearing and smearing. This is because transparency is essential. In addition, the eye makeup composition of the present invention can be applied without limitation to all eye makeup formulations that can use the same and similar purposes and effects of the present invention, such as transparent mascara, brow, eyeliner, etc., in addition to the top coat formulation.

Hereinafter, the configuration of the present invention will be described in more detail. However, the following content describes only the most representative embodiments to help the understanding of the present invention, and the scope of the present invention is not limited thereto, and it should be understood that the present invention encompasses all ranges equivalent to the following content.

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

Specifically, the thickener of the present invention is an amide-based polymer and dextrin palmitate / ethylhexanoate (Dextrin Palmitate / Ethylhexanoate) is used alone or a mixture of two or more thickeners selected from the group consisting of do.

More preferably, as the amide-based polymer thickener, bis-stearyl ethylenediamine/neopentyl glycol/stearyl hydrogenated dimer dilinoleate copolymer (Bis-Stearyl Ethylenediamine/Neopentyl Glycol/Stearyl Hydrogenated Dimer Dilinoleate Copolymer) and / or Ethylenediamine/Hydrogenated Dimer Dilinoleate Copolymer Bis-Di-C14-18 Alkyl Amide.

Compared to the thickeners used in conventional eye makeup compositions, amide-based polymers are not typically utilized as thickeners for eye makeup, particularly mascara or top coat formulations, and dextrin palmitate/ethylhexanoate only controls viscosity. While it was limited to mixing with other conventional oily thickeners for the purpose, in the present invention, one or more mixtures selected from the group consisting of the amide-based polymer and/or dextrin palmitate/ethylhexanoate are used as a thickener By doing so, it is possible to form a transparent appearance of the composition and at the same time realize an appropriate viscosity suitable for use.

The total content of the thickener used in the present invention may depend on the content of the thickener that may be conventionally added to prepare the eye makeup composition. Preferably, it may be 1 to 30% by weight based on the total weight of the volatile oil, and more preferably 20% by weight. If the thickener is included in less than 1% by weight, the thickening effect is reduced and a formulation that flows down like water is easily formed, which may cause discomfort in use, and if it is 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 a viscosity of less than 30,000 cps, it flows down like water, making it unsuitable for use, and at a viscosity of more than 300,000 cps, the composition becomes too stiff and there is a problem that it is difficult to apply it to a brow or eyelashes, but the composition of the present invention is used as a composition having a viscosity within the above range Convenience is improved. Preferably, the specific component combination can be adjusted to form a viscosity of 30,000 to 200,000 cps, more preferably 100,000 cps at a medium solid content of 20% by weight of the volatile oil.

The more preferable viscosity range corresponds to a range most suitable for use as a top coat formulation for mascara and the like. This is because the viscosity of the mascara formulation is generally formed around 200,000 cps, so the top coat overlying it needs to form a relatively lower viscosity to provide good spreadability and feeling of use.

However, the application examples of the eye makeup composition of the present invention are not necessarily limited thereto, and may be appropriately adjusted to form the most suitable viscosity as needed. For example, when it is intended to be used as a formulation that is applied alone without re-applying on a certain formulation, such as transparent mascara or brow, it may be desirable to have a higher viscosity than the top coat formulation, so in this case, a thickener that forms a relatively high viscosity You can choose a combination of In particular, dextrin palmitate/ethylhexanoate tends to form a relatively high viscosity compared to the two preferred types of amide-based polymer thickeners of the present invention. However, even in this case, the viscosity of the composition does not exceed a maximum of 300,000 cps.

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

The volatile oil having the highest compatibility with the specific thickener described above includes a hydrocarbon-based volatile oil and/or a silicone-based volatile oil. Preferably, it may be in a form that includes a hydrocarbon-based volatile oil and optionally further includes a silicone-based volatile oil. In the case of silicone oil, transparency of the composition can be ensured, but this is because there is a tendency for the grading effect to be small compared to hydrocarbon-based oil.

As the hydrocarbon-based volatile oil, branched alkanes, esters, or mixtures thereof having 8 to 16 carbon atoms may be used. More preferably, as isoalkane, at least one material selected from the group consisting of isodecane, isododecane and isohexadecane may be used.

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

Hereinafter, test examples for helping the understanding of the effects of the present invention are described. However, the following test examples only correspond to test examples related to the configuration and effect of the present invention, and the scope and effect of the present invention are not limited thereto.

Eight thickeners having affinity with volatile oils were used in the test (Table 1).

< test example 1> - Transparency test

One) test example 1-1: thickener single use

In order to check the transparency, each of the thickeners was added to isododecane, a volatile oil, to prepare 8 kinds of compositions.

The transparency of the composition observed visually after preparation can be confirmed through FIG. 1 . Referring to FIG. 1, among the eight kinds of thickeners, ethylenediamine/hydrogenated dimer dilinoate copolymer bis-di-C14-18 alkylamide (No. 3), bis-stearyl ethylenediamine/neopentyl glycol It was confirmed that the composition forms a transparent appearance when three thickeners of chol/stearyl hydrogenated dimer dirinoate copolymer (No. 7) and dextrin palmitate/ethylhexanoate (No. 4) are added. can

For more accurate evaluation, transparency was measured according to the following measurement method.

How to measure

Using an applicator, each of the eight thickener compositions for isododecane is applied to a uniform thickness (100um) on a black background.

- Using a colorimeter (model name: Minolta CM5), measure the value of the base material before application and the value after application of the thickener composition. In the colorimeter measurement value, the L value represents the color, and dE can be interpreted as a difference from the L value of the target.

- In general, if the dE value is 1.5 or less or the KS value is 90 or more, it can be judged as the same color as the target, so it is considered a transparent composition.

Measurement result

Measurement results using the color difference meter are shown in Table 2 and FIG. 2 below.

2 is a graph showing the K/S value according to each thickener (indicated by Data No.) among the results of Table 2;

Data No. thickener (product name) dE *ab(D65) L*(D65) K/S St.(Max) Target black paper ( reference value ------ 22.21 ------ One SC401 91.06 0.16 2 PE wax 32.42 53.2 6.17 3 A2614V 0.18 22.1 99.21 4 Rheopearl 1.35 23.56 90.74 5 Uniclear 10.95 36.72 6 Rheopearl KL 1.76 23.96 85.33 7 C75V 0.12 22.12 99.34 8 CL300 11.53 33.58 35.03

Referring to Table 2, the thickener of the composition evaluated as transparent as having a dE value of 1.5 or less is ethylenediamine/hydrogenated dimer dilinoate copolymer bis-di-C14-18 alkylamide (A2614V, No. 3) , dextrin palmitate/ethylhexanoate (Rheopearl TT, No. 4), bis-stearyl ethylenediamine/neopentyl glycol/stearyl hydrogenated dimer dirinoate copolymer (C75V, No. 7) It can be seen that there are a total of three types of thickeners. In addition, referring to Table 2 and FIG. 2, it can be confirmed that the thickener of the composition satisfying the K/S value of 90 or more is also the same as the three kinds of thickeners.

The three thickeners are the same as the thickeners of the three compositions that were observed to be transparent in appearance in FIG. 1 .

2) test example 1-2: thickener mixed use

It was checked whether the composition forms a transparent appearance even when the three kinds of thickeners are not used alone, and two or more kinds of thickeners are used in combination.

Referring to the photos of each composition shown in FIG. 3, among the three thickeners, ethylenediamine/hydrogenated dimer dilinoate copolymer bis-di-C14-18 alkylamide (No. 3) and bis-stearyl A composition using a mixture of two thickeners of ethylenediamine/neopentyl glycol/stearyl hydrogenated dimer dilinoate copolymer (No. 7) (left) and dextrin palmitate for the two thickeners As a result of observing the appearance of the composition (right) used by further mixing /ethylhexanoate (No. 4), it can be confirmed that all are formed in a transparent formulation.

< test example 2> - Viscosity test

A viscosity measurement test was performed on the eight compositions used to measure the transparency. The measurement method is as follows.

How to measure

Viscosity was measured using a Brookfield Viscometer HA DV-Ⅲ from Brookfield, and the viscosity value was derived by repeating the measurement three times at room temperature (25° C.) with Spindle No. 29 and then obtaining the average value. did.

Measurement result

The measured viscosity result values are presented as a graph in FIG. 4 . 4, the thickener included in the composition satisfying the range of 30,000 to 300,000 cps corresponding to the appropriate viscosity range of the eye makeup composition is ethylene/acrylic acid copolymer (SC401, No. 1), ethylenediamine/hydro Genetized dimer dirinoate copolymer bis-di-C14-18 alkylamide (A2614V, No. 3), dextrin palmitate/ethylhexanoate (Rheopearl TT, No. 4), bis-stearyl ethylenediamine/neo It can be confirmed that it is a pentyl glycol/stearyl hydrogenated dimer dirinoate copolymer (C75V, No. 7) and polyethylene (PE wax, No. 2).

However, in the case of the ethylene/acrylic acid copolymer (SC401, No. 1) and polyethylene (PE wax, No. 2), it was confirmed that a transparent composition could not be formed as a result of the above-described transparency measurement test, so the transparency and viscosity of the composition It is not suitable as a thickener that simultaneously satisfies

Therefore, taking the results of Test Examples 1 and 2 above, the thickener that satisfies the transparency and viscosity of the composition at the same time is ethylenediamine/hydrogenated dimer dilinoate copolymer bis-di-C14-18 alkylamide (A2614V, No 3), dextrin palmitate/ethylhexanoate (Rheopearl TT, No. 4), bis-stearyl ethylenediamine/neopentyl glycol/stearyl hydrogenated dimer dirinoate copolymer (C75V, No. 4). It can be seen that there are 3 types of thickeners in 7).

As exemplified in the present specification, the three kinds of thickeners correspond to the amide-based polymer and dextrin palmitate/ethylhexanoate, which are the thickeners of the present invention, from which the effect of the present invention can be confirmed.
