Description

Low viscosity eye make-up cosmetic composition comprising wax

The present invention relates to a low-viscosity eye makeup composition comprising crystalline and amorphous waxes, and to an eye makeup cosmetic composition with improved waterproofness.

The easy-to-carry and easy-to-use brush-pen eyeliner is loved by many for its natural color development and soft application. However, when using the brush pen eyeliner, the surface of the brush hardens easily, and accordingly, frequent washing is required or the number of times of pumping is increased when reused.

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

Specifically, the brush pen eyeliner has a constraint that 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 a nozzle. Therefore, most conventional brush-pen-type eyeliners cannot use wax with a large increase in viscosity, but are manufactured based on an aqueous base.

However, in this case, there are concerns such as a decrease in pigment adhesion due to non-use of wax, a problem of powder falling, and bleeding due to reduced durability. It dries to form a film, and accordingly, the surface of the brush hardens easily.

This hardening of the brush greatly reduces the satisfaction of using the makeup product. Therefore, in order to solve this problem, various studies have been conducted from the prior art, but it is considered that the most effective solution is to include a wax without using an excessive amount of a film forming agent.

In addition, if a composition based on an oily base is provided using wax, the waterproof ability can also be significantly improved. is increasing

However, manufacturing an eyeliner composition that can achieve a low viscosity of 100 to 2000 cps, including wax, and secure durability without overuse of a film agent cannot be easily implemented with any combination of waxes, and its technical limitations is in existence.

Waterproof eye makeup composition with excellent durability (Korea Patent No. 10-1060805)

Accordingly, it is an object of the present invention to provide a low-viscosity eye makeup composition comprising a wax.

Another object of the present invention is to provide an eye makeup composition with improved waterproofness.

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

In order to preferably exhibit the effects 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, and more preferably, the crystalline wax within the above total content range. The weight ratio of the amorphous wax to the ratio is 1:0.1 to 1:0.7.

By using the above-described problem solving means, the eye makeup composition of the present invention can form a low-viscosity composition excellent in ejection power while including wax. In addition, the eye makeup composition of the present invention may have improved waterproofness by being formed as an oily base formulation.

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

Unlike the conventional aqueous base formulation, the eye makeup composition of the present invention is an oily base formulation containing wax. Although the eye makeup composition of the present invention includes wax, it forms a viscosity in the range of 100 to 2,000 cps by limiting the combination and content thereof, and improves the durability and pigment adhesion after application of the makeup composition without excessive use of a film former. can

In particular, when the composition is used in a makeup product in the form of a brush pen, the discharge of the composition through the nozzle can be maintained at an appropriate level and it does not contain an excessive amount of film forming agent, so the surface of the brush with the composition does not harden easily, which is more effective.

Therefore, the eye makeup composition of the present invention is preferably used for all other types of eye makeup products that are used in a way that the composition is directly applied by discharging the composition through a brush pen type or nozzle, for example, a brush pen type eye liner composition. However, the present invention is not limited thereto.

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

The term 'crystalline wax' means any kind of wax that forms crystals. However, those corresponding to the following amorphous waxes are excluded.

'Amorphous wax' refers to a wax having a characteristic of making wax crystals very small or eliminating crystals (non-crystallization) when mixed with crystalline wax.

Hereinafter, 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.

In the present invention, it is possible to balance the viscosity of the composition by using a combination of the crystalline wax and the amorphous wax. Specifically, when only the crystalline wax is used, the durability and viscosity are too high, and when only the amorphous wax is used, there is a problem of the durability and the viscosity are too low. can be In addition, in the present invention, by limiting the content and combination weight ratio of the crystalline wax and the amorphous wax, an eye makeup composition exhibiting an optimal function can be provided.

crystalline wax

Generally, wax undergoes a phase change between a solid and a liquid before and after the melting point, and crystallization proceeds below the melting point, and is divided into plate-like crystals, needle-like crystals, and amorphous crystals according to the shape of the crystal.

The higher the crystallization property, the higher the viscosity of the wax, and the solidified wax film exhibits hard and firm properties. Therefore, the crystalline wax of the present invention improves the surface rigidity of the composition without the use of a film forming agent, and thereby prevents persistence and smearing after application. can

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

Specifically, paraffin wax is a mixture of alkane hydrocarbons represented by the chemical formula of CnH _{2n +2} (n≥19, preferably n=20-40), and is white and colorless derived from petroleum, coal, or oil shale. It is a soft solid substance at room temperature. The paraffin wax is insoluble in water, but has a property of being well soluble in ether, benzene, and ester.

Carnauba wax is a material obtained from the leaves of the palm family, and belongs to waxes having very high hardness among conventional waxes used as raw materials included in makeup compositions. In particular, it has hardening properties that are hardened to brown-yellow-dye brown, and it is easily hardened and brittle. In addition, it corresponds to a wax excellent in gloss, gloss, strength, hardenability, and microcrystallinity among plant-based waxes. When the carnauba wax is included in the makeup composition, its melting point can be increased by mixing with other oils or waxes, and when used, it is often used in a relatively small amount compared to other waxes used together. When the carnauba wax is included in mascara or the like, there is an advantage in that a water-resistant film can be formed.

Polyethylene wax is a low molecular weight polyethylene and has a waxy appearance. The polyethylene wax has an intermediate molecular weight of paraffin and polyethylene, and thus has an 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 paraffin.

Rice wax, also called rice bran wax or rice bran oil, can be extracted from rice bran. The main component is an ester of a higher fatty acid and a higher alcohol, and has good compatibility with copper, vegetable, mineral, fatty acid salts, glycerides, and hydrocarbon waxes. The rice wax has a low HLB value of 6 to 9, and requires an emulsifier when used, unlike natural waxes such as carnauba wax and beeswax. In general, it is often selectively applied to a makeup composition.

Ozokerite is a natural mineral wax, a hydrocarbon wax derived from mineral or petroleum sources. The melting point of the ozokerite is 65° C., and has a microcrystal structure composed of needles or short plates. In particular, it has excellent affinity with oil and excellent compatibility with paraffin wax. For example, when about 5 to 15% of the paraffin wax is added, the melting temperature thereof can be lowered to around 54° C. and the physical properties of the overall composition can be improved. 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. In addition, it can provide a soft feeling of use, stabilize an unstable emulsion state, and impart gloss and flexibility to the area where the makeup composition is applied.

On the other hand, the substance obtained by refining the ozokerite is called sericin.

Candelilla Wax Euphorbia cerifera Alcocer , Euphorbia antisyphilitica Zuccarini and Pedilanthus It is a natural ester extracted from the stems of Candelilla plants such as Boissier ( Euphorbiaceae ) . When the candelilla wax is included in the makeup composition, it is a water-insoluble thickener that stabilizes the unstable emulsion state of the composition and adjusts the viscosity and hardness of the makeup composition, and forms a film to gently wrap and protect the application area while providing a glow and flexibility. In addition, it blocks the evaporation of moisture in the application area and provides conditioning to maintain moisture.

Beeswax, also known as beeswax, exists in the form of a mixture containing palmitic acid ester of melicyl alcohol and serotic acid as main components, and various other fatty acids, alcohols, and higher hydrocarbons. The melting point of the beeswax is 62 ~ 63 ℃, it has a characteristic of having a little tackiness.

amorphous wax

In the present invention, the amorphous wax serves to lower the viscosity to maintain a low viscosity of an appropriate level so that the composition can be well discharged through the nozzle, and to suppress the formation of a film.

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

Microcrystalline wax is a microcrystalline wax mainly composed of isoparaffin, which has high flexibility and a relatively high melting point. The microcrystalline wax is classified as an amorphous wax because it has a characteristic of making the crystals very small or completely eliminating the crystals when mixed with other crystalline waxes, for example, paraffin wax.

The total content of the above-described crystalline wax and 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 wax is contained below the above range, it is difficult to sufficiently exhibit the intended effect of the present invention, for example, pigment adhesion, and the like. becomes high, and the composition discharge force passing through the nozzle is reduced.

In addition, the crystalline wax and the amorphous wax contained within the above total content range are made to be in a weight ratio of 1:0.1 to 1:0.7. When the content of the amorphous wax is less than 10% by weight compared to the crystalline form, the viscosity of the wax becomes excessively high and it is difficult to discharge the composition through the nozzle. persistence deteriorates.

On the other hand, the eye makeup composition of the present invention, in addition to including the crystalline wax and the amorphous wax as a basic composition as described above, selectively dyes, powders, dispersants, preservatives, It may further include thickeners, film formers, and other functional ingredients.

Hereinafter, Examples, Comparative Examples, and Evaluation Examples are presented to help the understanding of the present invention. However, since the following content is only an example of the configuration and effect of the present invention, 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 brush pen type eyeliner composition.

Examples 1 and 2 are eye makeup compositions according to the present invention, which are formulations containing both a crystalline wax and an amorphous wax. Specifically, in Example 1, the weight ratio of the crystalline wax to the amorphous wax was 3:2, and in Example 2, the weight ratio of the crystalline wax to the amorphous wax was 4.5:0.5, so that the content ratio of each wax was different.

Comparative Example 1 is a conventional eye makeup composition, which is an aqueous base formulation containing an excessive amount of a film former without including a wax. Comparative Example 2 is an oily base formulation eye makeup composition that does not contain wax and contains an excessive amount of a film former. Comparative Example 3 is an oil-based eyeliner composition containing only crystalline wax, and Comparative Example 4 is an oil-based eye makeup composition containing only amorphous wax.

< evaluation example 1> - discharge power test

In this evaluation example 1, after checking the viscosity of the compositions of Examples 1 to 2 and Comparative Examples 1 to 4, the ejection force of the compositions passing through the nozzle when applied to a brush pen-type product was evaluated.

As an evaluation method, after filling the composition of each of Examples 1 to 2 and Comparative Examples 1 to 4 in a brush pen-type eyeliner, click the pumping part of the contents to measure the number of clicks until the contents are wetted on the brush. was used.

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 Table 2, the viscosities of Examples 1 and 2, which are the eye makeup compositions of the present invention including both the crystalline wax and the amorphous wax, satisfied the range of 100 to 2,000 cps, which is a suitable viscosity range to be discharged through the nozzle. . Among Comparative Examples, Comparative Examples 1 to 2, which are formulations without wax, and Comparative Example 4, which includes only amorphous wax, satisfied the viscosity range that can be discharged through a nozzle. However, in the case of Comparative Example 3 including only crystalline wax, an excessively high viscosity was formed, and thus it was not suitable for use as a composition of a brush pen formulation.

The composition satisfying the above viscosity range was evaluated to also satisfy the discharge power at an appropriate level. In general, the proper discharge power of a brush pen type makeup product is evaluated by whether the brush is wetted with less than 10 clicks. In Example 1, in which the weight ratio of amorphous wax to crystalline wax is 3:2, the brush In the case of Example 2, which contained much less amorphous wax relative to the weight of relatively crystalline wax, 8 clicks, 3 more times, were required. As described above, although there was a difference in viscosity and discharge power depending on the specific wax composition, it can be seen that Examples 1 and 2 all have an appropriate discharge power according to the appropriate viscosity.

In addition, in Comparative Examples 1, 2 and 4 containing no wax or only amorphous wax, except for Comparative Example 3, which was not discharged at all due to excessively high viscosity including only crystalline wax, the discharge power was found to be at an appropriate level. was evaluated. In particular, it can be seen that the composition of Comparative Example 2, which does not contain any wax as an oily base formulation, can exhibit excellent discharge characteristics.

< evaluation example 2> - brush Surface Hardness Test

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

Assessment Methods

- After leaving the brush pen type eye makeup product used more than 10 times for 3 days (the brush surface is dry), perform the above discharge test to measure the number of clicks it takes to wet the dried brush surface again.

- ◎: within 5 re-clicks, ○: re-clicks 6 to 10 times, △: re-clicks: 11 to 15 times, X: re-clicks 16 times or more.

- The less the number of re-clicks, the less the hardness of the brush surface 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 former, had a somewhat hard surface of the brush with 16 or more re-clicks, whereas Examples 1 and 1 according to the present invention It can be seen that the composition of Example 2 maintains the brush surface smooth enough to wet the brush even when the composition of Example 2 is clicked for the first use or less.

In the case of Comparative Example 3, since the discharge was not performed, the evaluation was omitted. On the other hand, in Comparative Example 2, the surface of the brush as an oily base was maintained smooth, and in Comparative Example 4, the smooth surface was maintained by the sole effect of the amorphous wax.

< evaluation example 3> - feeling evaluation

In this evaluation example 3, sensory evaluation was performed on the properties of dusting, spreading, waterproofing, and drying speed.

In the sensory evaluation, the composition of Examples 1 to 2 and Comparative Examples 1 to 4 was applied to a group of 30 members, respectively, and the following evaluation items were evaluated as X, △, ○, ◎ ( However, X: poor / △: average / ○: excellent / ◎: very good). The final evaluation result for each item was derived as the average value of the total sum after quantifying the evaluation index for each item as 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 fall ○ ◎ △ X △ X Bleed Persistence ◎ ◎ ○ X △ △ waterproof ◎ ◎ X ◎ ◎ ○ drying speed ○ ◎ ○ ○ ○ △

Referring to Table 4, it can be seen that the eye makeup compositions of Examples 1 and 2 according to the present invention were evaluated very excellently in powder falloff, smear persistence, waterproof power and drying speed. In Comparative Example 1, which is a composition of an aqueous base formulation that does not contain conventional wax, the powder falling property and waterproofing power were particularly poorly evaluated, whereas in the compositions of Examples 1 and 2, the powder falling was improved by including the wax, It can be seen that the waterproof power is improved by being prepared as an oily base formulation.

In addition, Comparative Examples 2 and 4, which were confirmed to have good discharge force and smooth brush surface in Evaluation Examples 1 and 2, showed severe powder fall and spread in the feeling of use, and in Comparative Example 4, the drying rate was also evaluated as low. It can be confirmed that the formulation is unsuitable for actual use.

In particular, as a result of comparing the evaluations of Comparative Example 2 and Examples 1 and 2 of the present invention, which are the same as those prepared in the oily base formulation, but differ only in the presence or absence of wax, the content of the wax indicates the adhesion of the pigment and the composition after application of the composition. It can be seen that this has a significant impact on sustainability.

In addition, if the evaluation results of Comparative Example 4 and Examples 1 and 2, which are oily base formulations containing only amorphous wax, are compared, it can be seen that the crystalline wax exerts a main function in terms of pigment adhesion and durability improvement.
