Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a low-viscosity eye makeup composition comprising a wax,

The present invention relates to a low viscosity eye makeup composition comprising crystalline and amorphous waxes and to an eye makeup cosmetic composition having improved water proofing properties.

The easy-to-carry and easy-to-use brush pen eyeliner is loved by natural coloration and soft feeling. However, the brush pen eyeliner hardens the surface of the brush easily when it is used, and therefore, it requires troublesome cleaning or increases the number of times of pumping when reusing.

Due to the structural characteristics of the brush pen eyeliner, the materials that can be used as the composition are limited. The stiffness of the brush surface is caused by this problem.

Specifically, the brush pen eyeliner has a limitation that the viscosity of the composition must be formed into a liquid formulation having a very low viscosity (100 to 2000 cps) because the composition must be discharged through the nozzle. Therefore, most of the conventional brush pen eyeliner was manufactured based on the water base without using the wax having a large viscosity increase.

However, in this case, there is a concern that the adhesion of the coloring matter due to the wax is not used, the dropping of the powder due to the use of the wax, and the smear caused by the decrease in the durability. In order to compensate for this, an excessive amount of film forming agent has been used. There is a phenomenon that the surface of the brush is easily hardened due to the characteristic of being dried and forming a film.

The problem of hardening of the brushes greatly reduces the satisfaction of use of the makeup product. Therefore, in order to solve this problem, various researches have been carried out conventionally, but it is considered that the most effective solution is to include wax without using excessive amount of film forming agent.

In addition, providing a composition based on an oil-in-water base using wax may significantly improve the water proofing ability. Therefore, the formulation containing wax is the most preferable form capable of improving both feeling and functionality. Is increasing.

However, it is not possible to easily manufacture an eyeliner composition which can realize low viscosity of 100 to 2000 cps including wax and maintain persistence without overuse of the film-use agent, And the like.

A waterproof eye makeup composition having excellent durability (Korean Patent No. 10-1060805)

It is therefore an object of the present invention to provide a low viscosity eye makeup composition comprising a wax.

Yet another object of the present invention is to provide an eye makeup composition with improved water proofing ability.

The present invention provides an eye makeup composition comprising a crystalline wax and an amorphous wax.

In order to preferably exhibit the effect of the present invention, the total content of the crystalline wax and the amorphous wax is 0.1 to 10% by weight based on the total weight of the total composition, more preferably, the crystalline wax The weight ratio of the non-crystalline wax to the non-crystalline wax is 1: 0.1 to 1: 0.7.

By using the above-mentioned means for solving the problems, the eye makeup composition of the present invention can form a low-viscosity composition containing wax and having excellent soil power. In addition, the eye makeup composition of the present invention can have improved water proofing ability by being formed into an oil based base formulation.

The present invention provides an eye makeup composition comprising a crystalline wax and an amorphous wax.

The eye makeup composition of the present invention is an eye-makeup composition of an oil-based base form containing wax unlike the conventional water based base formulation. The eye makeup composition of the present invention comprises wax but limits the combination and content thereof to form a viscosity in the range of 100 to 2,000 cps and improves the durability and dye adhesion after application of the makeup composition without excessive use of the film forming agent .

Particularly, when the composition is used in a make-up product of a brush pen type, the discharge of the composition through the nozzle can be maintained at an appropriate level and the brush-coated surface of the composition is not easily hardened because it does not contain excessive film-

Therefore, the eye makeup composition of the present invention is preferably used for a brush pen or any other type of eye makeup product used in a manner that the composition is directly applied through a nozzle to be applied, But is not limited thereto.

On the other hand, with respect to terms used in this specification,

&Quot; Crystalline wax " refers to all kinds of waxes that form crystals. However, those which fall under the following amorphous waxes are excluded.

&Quot; Amorphous wax " means a wax having properties of making the wax crystal very small or removing crystals (non-crystallizing) when mixed with the crystalline wax.

Hereinafter, the present invention will be described in more detail. It is to be understood, however, that the scope of the present invention is not limited thereto and that the present invention covers all of the equivalent scope of the following description.

In the present invention, the viscosity of the composition can be maintained in a balanced manner by using a combination of a crystalline wax and an amorphous wax together. Concretely, when only crystalline wax is used, there is a problem that the persistence and viscosity are too high, and when only amorphous wax is used, persistence and viscosity are too low. When both waxes are mixed and contained, both hardness and flexibility are manifested . In addition, in the present invention, the content of the crystalline wax and the amorphous wax and the combination weight ratio are limited, thereby providing an eye makeup composition exhibiting an optimal function.

Crystalline wax

In general, wax phase-shifts to solid and liquid phase before and after melting point. Crystallization progresses below melting point, and it is divided into plate-like crystal, needle crystal and amorphous crystal according to the shape of crystal.

Since the wax has a high crystallization property and a high viscosity, the solidified wax film exhibits a rigid and rigid property. Therefore, the crystalline wax of the present invention improves the surface rigidity of the composition without using a film forming agent and prevents persistence and smear after application thereof .

The crystalline wax may be at least one selected from the group consisting of paraffin wax, carnauba wax, polyethylene wax, rice wax, ozokerite, sericin, candelilla wax, and beeswax.

Specifically, the paraffin wax is a mixture of alkane hydrocarbons represented by the formula CnH _{2n + 2} ( _n ≥19, preferably n = 20-40), which is a white, colorless It is a soft room temperature solid material. The paraffin wax does not dissolve in water but has a property of dissolving in ether, benzene, and ester.

Carnauba wax is a substance obtained from the leaves of palm plant, and belongs to a very high hardness wax among conventional waxes used as a raw material contained in makeup compositions. In particular, it has hardenability to cure into brown to yellowish-brownish brown and is easy to cure and to break easily. Also, among waxes of vegetable wax, it corresponds to wax having excellent glossiness, glossiness, rigidity, hardenability, microcrystallinity and the like. When the carnauba wax is included in the makeup composition, it can be mixed with other fats or waxes to increase its melting point. In use, it is often used in a relatively small amount compared to other waxes used together. When the carnauba wax is contained in mascara or the like, a water-resistant film can be formed.

The polyethylene wax is a low molecular weight polyethylene and has a wax-like appearance. The polyethylene wax has an intermediate molecular weight of paraffin and polyethylene, and thus has intermediate strength and intermediate heat resistance (melting point) of the two materials. The polyethylene wax may be contained together with paraffin to increase the melting point and strength of the paraffin.

Rice wax is also called rice bran wax or rice bran oil and can be extracted from rice bran. The main component is an ester of higher fatty acid and higher alcohol and has good compatibility with copper, plant and mineral, fatty acid salt, glyceride, and hydrocarbon wax. The HLB value of the above-mentioned rice wax is as low as 6 to 9, and an emulsifier is required in use, unlike natural waxes such as carnauba wax and bees wax. Generally, it is often applied selectively to a makeup composition.

Ozokerite is a natural mineral wax and is a hydrocarbon wax derived from mineral or petroleum raw materials. The melting point of the ozokerite is 65 DEG C, and it has a microcrystalline structure composed of needles and a short plate. In particular, it has excellent affinity with oil and is excellent in compatibility with paraffin wax. For example, when 5 to 15% of paraffin wax is added, the melting temperature of the wax can be lowered to about 54 캜 and the physical properties of the composition can be improved overall. When the ozokerite is included in the makeup composition, it serves to improve the viscosity and hardness of the composition as a water-insoluble thickener. It may also provide a soft feel, stabilize unstable emulsification conditions, and impart shine and suppleness to the area to which the makeup composition is applied.

On the other hand, a substance obtainable by purifying the ozokerite is called sericin.

Candelilla wax is available from Euphorbia cerifera Alcocer , Euphorbia antisyphilitica Zuccarini and Pedilanthus Boissier ( Euphorbiaceae ), and the like. When the candelilla wax is contained in the makeup composition, it stabilizes the unstable emulsified state of the composition as a water-insoluble thickener, controls the viscosity and hardness of the makeup composition, forms a film to smoothly wrap the coated portion, And flexibility. In addition, moisture evaporation at the application site is blocked, and conditioning is provided to maintain moistness.

Beeswax is also known as beeswax and is present in the form of a mixture containing palmitic acid esters of melissyl alcohol and other various fatty acids, alcohols and high-grade hydrocarbons as a main component. The melting point of the beeswax is 62 to 63 캜, and it has a characteristic of having a little stickiness.

Amorphous  Wax

In the present invention, the amorphous wax has a function of lowering the viscosity and suppressing film formation so as to maintain an appropriate level of low viscosity through which the composition can be discharged through the nozzle.

The amorphous wax is not limited thereto, but microcrystalline wax is representative.

Microcrystalline wax is a microcrystalline wax composed mainly of isoparaffin. It is highly flexible and has a relatively high melting point. The microcrystalline wax is classified as noncrystalline wax because it has a characteristic that when crystals are mixed with other crystalline waxes such as paraffin wax, the crystals are very small or crystals are completely eliminated.

The total content of the crystalline wax and the amorphous wax is preferably 0.1 to 10% by weight based on the total weight of the eye makeup composition. When the total content of the waxes is less than the above range, the intended effect of the present invention, such as the coloring ability, etc., is difficult to sufficiently exhibit. When the total amount of the waxes is above the above range, And the output of the composite soot passing through the nozzle is reduced.

In addition, the crystalline wax and the amorphous wax contained within the total content range are set to a weight ratio of 1: 0.1 to 1: 0.7. When the content of the amorphous wax is less than 10% by weight, the viscosity of the wax becomes too high and the composition is difficult to discharge through the nozzle. When the amount of the amorphous wax is more than 70% by weight, the effect of decreasing the viscosity is large. However, Persistence deteriorates.

In addition, the eye makeup composition of the present invention may contain a crystalline wax and an amorphous wax as basic components, as well as a colorant, a powder, a dispersant, a preservative, Thickeners, film formers, and other functional ingredients.

Hereinafter, examples, comparative examples and evaluation examples are presented to facilitate understanding of the present invention. It should be noted, however, that the following contents are only examples of the constitution and effect of the present invention, and thus the scope of the present invention is not limited thereto.

< Example  1 to 2 and Comparative Example  1 to 4>

The eye makeup compositions of Examples 1 to 2 and Comparative Examples 1 to 4 were prepared according to the compositions shown in Table 1 below. The eye makeup composition is specifically a pencil-type eyeliner composition.

Examples 1 and 2 are formulations comprising the crystalline wax and the amorphous wax together as an eye makeup composition according to the present invention. Specifically, in Example 1, the weight ratio of the amorphous wax to the crystalline wax was set to 3: 2, and in Example 2, the weight ratio of the amorphous wax to the crystalline wax was set to 4.5: 0.5.

Comparative Example 1 is an aqueous base make-up composition that does not contain wax but contains an excess of film-forming agent as a conventional eye makeup composition. Comparative Example 2 is an oily makeup composition of an oily base formulation that does not contain a wax but contains an excessive amount of a film former.

< Evaluation example  1> - Toe output  Test

In this evaluation example 1, the viscosity of the compositions of Examples 1 to 2 and Comparative Examples 1 to 4 was checked, and when the composition was applied to a brush-type product, the compositions of the compositions evaluated the throughput through the nozzle.

As the evaluation method, a method of filling the brush-type eyeliner with each of the compositions of Examples 1 to 2 and Comparative Examples 1 to 4 and then measuring the number of clicks until the content of the brush is wetted by clicking on the pumping portion of the contents Respectively.

The evaluation results are shown in Table 2 below.

Evaluation items Example  One Example  2 Comparative Example  One Comparative Example  2 Comparative Example 3 Comparative Example 4 Viscosity (cps) 900 1,800 950 1,000 4,200 450 Discharge  Clicks 5 8 6 5 X 2

Referring to the above Table 2, the eye makeup compositions of the present invention including both the crystalline wax and the amorphous wax had satisfactory viscosity ranges of 100 to 2,000 cps, which were suitable for ejection through nozzles . In Comparative Examples 1 to 2, which are formulations not containing wax, and Comparative Example 4, which only contains amorphous wax, the viscosity range that can be discharged through a nozzle was satisfied. However, in the case of Comparative Example 3 containing only crystalline wax, an excessively high viscosity is formed and it is not suitable to be used as a composition for a brush pen formulation.

The composition satisfying the viscosity range was evaluated as satisfying the appropriate level of soil power. In the case of Example 1 where the weight ratio of the amorphous wax to the crystalline wax is 3: 2, it is preferable to use the brush in only 5 clicks. In the case of Example 2, which was moist and relatively much less amorphous wax relative to the weight of the crystalline wax, three more clicks were required. As described above, there was a difference in viscosity and soil power according to the specific wax composition, but it can be confirmed that Examples 1 and 2 have a proper soil power according to the appropriate viscosity.

In Comparative Examples 1, 2 and 4, which contained only wax or only amorphous wax, except for Comparative Example 3, which was not discharged at all due to the formation of an excessively high viscosity including only crystalline wax, Respectively. In particular, it can be seen that the composition of Comparative Example 2, which contains no wax at all as an oil-based base formulation, exhibits a superior aspect in terms of the soil power output.

< Evaluation example  2> - brush  Surface hardening test

In the evaluation example 2, it was confirmed how hard the surface of the brush hardened after the compositions of the above Examples 1 and 2 and Comparative Examples 1 to 4 were wetted with the brush pen surface. The evaluation method is as follows.

Assessment Methods

- Leave the brush-type eye makeup product that has been used more than 10 times for 3 days (with the brush surface dry), and then perform the above soil test to measure the number of clicks required to wet the dried brush surface again.

-: The number of clicks is 5 or less, the number of clicks is 6 to 10, the number of clicks is 11 to 15, and the number of clicks is 16 or more.

- The less the number of re-clicks, the less the surface hardness of the brush is evaluated.

The evaluation results are shown in Table 3 below.

Evaluation items Example  One Example  2 Comparative Example  One Comparative Example  2 Comparative Example 3 Comparative Example 4 Viscosity (cps) 900 1,800 950 1,000 4,200 450 brush  Surface hardening ◎ ○ △ ○ _ ○

Referring to Table 3, the composition of Comparative Example 1, which is a conventional aqueous base formulation using an excessive amount of a film forming agent, hardens the surface of the brush harder than 16 times, It can be seen that the composition of Example 2 maintains the surface of the brush smoothly enough to sufficiently wet the brush even if it is reused for the first time or less.

In the case of Comparative Example 3, evaluation was omitted because no discharge occurred. On the other hand, in the case of Comparative Example 2, the surface of the brush was kept soft as an oil phase base, while in Comparative Example 4, a smooth surface was maintained due to the effect of the amorphous wax alone.

< Evaluation example  3> - Feeling  evaluation

In the evaluation example 3, sensory evaluation was performed on the dropping of the powder, persistence of blurring, water proofing ability, and drying speed characteristics.

The sensory evaluation was carried out on a group consisting of 30 members, and the compositions of Examples 1 to 2 and Comparative Examples 1 to 4 were evaluated respectively, and evaluated as X,?,?, And? X: poor /?: Fair / good: excellent / good: very good). The final evaluation result for each item was derived from the average value of the total sum after numericalizing the evaluation index for each item from 1 to 5 points.

The evaluation results are shown in Table 4 below.

Evaluation items Example  One Example  2 Comparative Example  One Comparative Example  2 Comparative Example 3 Comparative Example 4 Powder drip ○ ◎ △ X △ X Smear persistence ◎ ◎ ○ X △ △ Water proof ◎ ◎ X ◎ ◎ ○ Drying rate ○ ◎ ○ ○ ○ △

Referring to Table 4, it can be seen that Examples 1 and 2, which are the eye makeup compositions according to the present invention, were evaluated to have excellent powder dropping, smudge persistence, water proofing ability and drying speed. Comparative Example 1, which is a composition based on an aqueous base formulation not containing waxes in the past, evaluated the powder dropping property and water proofing force to be particularly poor, whereas in the compositions of Examples 1 and 2, the dropping of the powder was improved by including wax, It can be seen that water proofing is improved by being made into an oil based formulation.

Also, in Comparative Examples 2 and 4, in which it was confirmed that the toe output was good and the brush surface was maintained smooth in the evaluation examples 1 and 2, flaking and blurring were likely to occur in feeling, and the drying speed in Comparative example 4 was also low And thus it can be confirmed that the formulation is unsuitable for actual use.

Particularly, in the case of Comparative Example 2 in which the wax is contained only in the same manner as in the preparation of the oil base formulation, the results of the evaluation of Examples 1 and 2 of the present invention are compared with each other. And it has a great influence on sustainability.

In comparison with the evaluation results of Comparative Example 4, which is an oil phase base formulation containing only amorphous wax, and Examples 1 and 2, it can be seen that the crystalline wax exerts its main function in improving the dye adhesion and persistence.
