Abstract

The present invention provides a non-transfer nonaqueous cosmetic composition for lip makeup, and a production method thereof. The cosmetic composition according to one aspect includes a surfactant and wax so that a polyol-dye system can be stably dispersed in oil, and polyol can be included in a high content ratio, thereby showing rich color development. When the cosmetic composition is applied, dye pigments stain the lips and oil is coated on the outside, and thus color may be prevented from staining hands or masks. Therefore, the cosmetic composition can be applied as a nonaqueous glossy formulation with excellent color development and excellent color bleeding resistance.

Description

Non-transfer anhydrous cosmetic composition for lip makeup

It relates to a cosmetic composition for non-aqueous lip makeup that does not stain and a method for manufacturing the same.

Pigments used in cosmetics include pigments and dyes. A pigment is a powdery colorant that is insoluble in water and most organic solvents, and a dye is a colorant that is soluble in water or oil.

Since it is generally difficult to include a dye in a cosmetic composition for lip makeup of a non-aqueous glossy formulation, pigments are dispersed in oil and used, resulting in gloss and color. However, as the mask becomes a part of daily life, when a glossy formulation using such a pigment is applied to the lips, a problem arises in that the color is dirty around the mouth due to friction with the mask.

Therefore, it is necessary to develop a cosmetic composition for lip makeup having a non-aqueous glossy formulation that does not stick to a mask or the like.

polyols; dyes; Surfactants; And it provides a cosmetic composition for makeup of a non-aqueous formulation containing a wax.

It provides a method for preparing the cosmetic composition for makeup of the non-aqueous formulation.

One aspect is a polyol; dyes; Surfactants; And it provides a cosmetic composition for makeup of a non-aqueous formulation containing a wax.

By using a polyol-dye system, the dye is dispersed in oil, and when applied to the skin, the dye is colored on the skin (eg, lips) and the outside is coated with oil, so that the color is not stained. Thus, the composition may be non-bleeding, and may have, for example, improved color bleeding resistance.

Since the polyol phase and the oil phase are immiscible, in the past, it was possible to disperse the particles only by using a specific type of wax (eg, beeswax, tribehenin). However, since the composition can better disperse the polyol and the oil phase by using a surfactant, various types of waxes can be used to give various feelings of use regardless of a specific type of wax, and the content ratio of polyol can be increased. It is possible to develop a darker color than before.

The polyol means an alcohol having two or more hydroxyl groups in the same molecule, and any polyol commonly used in the art may be included without limitation. In one embodiment, the polyol may include glycerin, butylene glycol, dipropylene glycol, propylene glycol, pentylene glycol, or a combination thereof. In one embodiment, the polyol may include glycerin, butylene glycol, or a combination thereof. In one embodiment, the polyol may be glycerin and butylene glycol. When glycerin and butylene glycol are included as the polyol, the mixed weight ratio of glycerin and butylene glycol is 1:10 to 10:1, 1:5 to 5:1, 1:3 to 3:1, 1:2 to 2 :1, 1:1 to 1:10, 1:1 to 1:5, 1:1 to 1:3, 1:1 to 1:2, for example 2:3. At this time, when the mixing ratio of glycerin and butylene glycol is less than the above range, there is a problem that it is not mixed with oil, and when it exceeds the above range, there is a problem that the pigment is not well dissolved.

1 to 15% by weight, 1 to 10% by weight, 3 to 10% by weight, 5 to 10% by weight, 6 to 10% by weight, 7 to 10% by weight, 8 to 10% by weight, Or it may be included in 9 to 10% by weight. The composition may include a high polyol content in a non-aqueous formulation by including a surfactant. When a high content of polyol is included in the composition, the ratio of the polyol-dye system in the composition increases, and thus the degree of color development may increase.

The dye (dye) refers to a colored material that is dissolved in water and oil and dispersed as a single molecule and combined with molecules such as fibers to color. The dyes may include all dyes commonly used in the art without limitation. For example, the dyes are Orange No. 205 (CI 15510), Red No. 227 (CI 17200), Red No. 104(1) (CI 45410), Yellow No. 5 (CI 15985), Yellow No. 4 (CI 19140), It may include Red No. 102 (CI 16255), Blue No. 1 (CI 42090), or a combination thereof.

Mixing the dye with a polyol can create a polyol-dye system or polyol-dye base. Accordingly, the composition may include a polyol-dye system or a polyol-dye base. The polyol-dye system or polyol-dye base is 1 to 15% by weight, 1 to 12% by weight, 1 to 11% by weight, 1 to 10% by weight, 5 to 15% by weight, 5 to 12% by weight based on the total weight of the composition %, 5 to 11% by weight, and 5 to 10% by weight. The polyol and dye are 100:1 to 100:20, 100:1 to 100:15, 100:1 to 100:10, 100:5 to 100:20, 100:5 to 100:15, 100:5 to 100 :10, for example, may be mixed in a weight ratio of 100:7, but is not limited thereto. When glycerin and butylene glycol are included as the polyol, the mixing weight ratio of glycerin:butylene glycol:dye may be 20 to 60:40 to 80:5 to 10, for example, 40:60:7. Since the composition includes the polyol and the dye in the mixing weight ratio, the dye is well dissolved in the polyol, and overall formulation stability may be excellent when mixed.

0.1 to 1.0%, 0.1 to 0.8%, 0.3 to 1.0%, 0.3 to 0.8%, 0.5 to 1.0%, or 0.5 to 0.8%, for example 0.7% by weight, relative to the total weight of the composition. It may be included as a %. If the content of the dye exceeds the above range, it may not dissolve well in the polyol, and the formulation may be separated. If the content of the dye is too small to be less than the above range, a desired color development effect may not be obtained.

The surfactant facilitates dispersion of the polyol phase and the oil phase, thereby increasing formulation stability. If the surfactant is not included, the formulation may be easily separated, and it may be difficult to include 5% by weight or more of polyol.

The surfactant may include a surfactant having a hydrophile-lipophile balance (HLB) value of 3 to 7, a surfactant having an HLB value of 16 to 20, or a mixture thereof. The surfactant may include a mixture of a surfactant having an HLB value of 3 to 7 and a surfactant having an HLB value of 16 to 20. The type of surfactant according to the HLB value is known in the art. Therefore, the surfactant may include all known surfactants having the HLB value. The surfactant may include glyceryl stearate, PEG-100 stearate, or a combination thereof. In one embodiment, the surfactant may be glyceryl stearate and PEG-100 stearate.

The surfactant may be included in 0.001 to 0.1% by weight, or 0.01 to 0.1% by weight, for example, 0.05% by weight, based on the total weight of the composition. If the content of the surfactant is out of the above range, the stability of the formulation may decrease and the separation of the formulation may occur.

The wax is a wax formed with high hardness, and forms a hardness to such an extent that flowability of the formulation does not occur after crystals are formed. The wax may be a wax having a relatively high melting point. The wax may have a melting point of 70° C. or higher, but is not limited thereto. Since the composition includes a surfactant to increase the dispersibility of the formulation, the wax is not particularly limited and any wax having high hardness may be used. The wax is polyethylene, glyceryl behenate, polyglyceryl-6 octastearate, microcrystalline wax, beeswax (beeswax), carnauba wax, candelilla wax, ceresin, tribehenin, paraffin wax, or a combination thereof It may include, but is not limited thereto. In one embodiment, the wax may be polyethylene, polyglyceryl-6 octastearate, glyceryl behenate, or a combination thereof.

The wax may be included in 1 to 7% by weight, 1 to 5% by weight, 1 to 4% by weight, 2 to 7% by weight, 2 to 5% by weight, or 2 to 4% by weight based on the total weight of the composition. If the content of wax is out of the above range, formulation stability may decrease.

The composition is a non-aqueous formulation. The “non-aqueous formulation” may be used interchangeably with “anhydrous formulation”. The composition is an “oil dispersion” formulation. Oil-dispersed formulations are oil-soluble components such as oils, fats, and lipids as basic components, and may not contain water. Accordingly, the composition may further include other oil components. The other oil component may include all conventional components that may be included in a cosmetic composition for lip makeup of a non-aqueous formulation.

The composition may be for lip makeup. The composition may be a formulation of any one of lipstick, lip gloss, lip lacquer, lip tint, lip oil, lip balm, lip cream and lip treatment, but is not limited thereto. For example, the composition may be used for various color makeup applications such as eye shadow, cheek, or blush, depending on the purpose of use. In one embodiment, the composition may be a cosmetic composition for lip makeup of a non-aqueous liquid formulation.

The cosmetic composition for making up the lips is applied to the lips, and as friction is applied, the polyol and dye move towards the lips, and the transparent oil moves outward. can Therefore, even after application to the lips, the composition does not smear on hands or masks, and can be colored on the lips for a long time to develop vivid colors.

The composition may additionally further contain ingredients commonly used in the field of cosmetics. For example, the composition may further include flavoring agents, preservatives, vitamins, antioxidants, and the like. A person skilled in the art can select an appropriate amount of the commonly used components according to the purpose and use.

Another aspect provides a method for preparing the cosmetic composition according to one aspect.

The method includes preparing a first mixture comprising a surfactant and a wax; and

and adding a second mixture comprising a polyol and a dye to the mixture.

The first mixture may further include an oil component.

The method may further include homogenizing a third mixture in which the second mixture is added to the first mixture. Through the homogenization step, an oil-dispersible cosmetic composition may be produced.

Details of the surfactant, wax, polyol, dye, oil, and cosmetic composition are as described above.

According to the above method, the immiscible polyol phase and oil phase can be stably dispersed by using a surfactant and a wax.

Redundant content is omitted in consideration of the complexity of the present specification, and terms not defined otherwise in the present specification have meanings commonly used in the technical field to which the present invention belongs.

The cosmetic composition according to one aspect may stably disperse a polyol-dye system in oil by including a surfactant and a wax, and may include a high content ratio of polyol to exhibit deep color development. When the cosmetic composition is applied, the dye pigment is colored on the lips, and the oil is coated on the outside, so that the color may not be smeared on the hand or mask. Therefore, it can be applied as a non-aqueous glossy formulation with excellent color development and excellent color bleeding resistance.

Example 1 and Comparative Example 1. Preparation of cosmetic composition for lip makeup

A cosmetic composition for lip makeup was prepared with the ingredients and contents (% by weight) shown in Table 1 below.

Specifically, component A in Table 1 was weighed and dissolved by heating in a beaker. Component B (i.e., wax) was added to component A and dissolved at 90°C. After weighing component C in another beaker and dissolving it by heating, it was added to the mixture of components A and B and dispersed in a homogenizer at 7000 rpm for 5 minutes. It was placed in a container and cooled at room temperature to prepare a cosmetic composition for lip makeup.

Example 1 used 0.05% by weight of glyceryl stearate and PEG-100 stearate as surfactants. As the surfactant, a mixture of glyceryl stearate and PEG-100 stearate in a mixing weight ratio of 50:50 was used. Comparative Example 1 did not include a surfactant.

Examples 2-5 and Comparative Examples 2-6. Preparation of cosmetic composition for lip makeup

First, a polyol-dye base was prepared. The polyol-dye base was prepared by mixing glycerin:butylene glycol:dye in a ratio of 2:3:0.35.

A cosmetic composition for lip makeup containing 2% by weight, 5% by weight, 7% by weight, and 10% by weight of the polyol-pigment base, respectively, was prepared. At this time, Examples 2 to 5 included a surfactant, and Comparative Examples 2 to 5 did not include a surfactant.

Meanwhile, Comparative Example 6 did not include a surfactant, and used an oil-organic pigment base instead of a polyol-color base.

Table 2 below shows the components and contents (wt%) of each composition. The manufacturing method of each composition was the same as that of Example 1 and Comparative Example 1.

Experimental Example 1. Evaluation of polyol-dye base dispersibility according to the presence or absence of surfactant

An experiment was conducted to evaluate the dispersibility of the polyol-dye base according to the presence or absence of a surfactant.

Specifically, Example 1 including a surfactant and Comparative Example 1 not containing a surfactant were stored at 70° C. for 3 hours while observing the appearance to confirm whether the formulations were separated.

1 shows the dispersion force evaluation results of Comparative Example 1 (Experiment 1) and Example 1 (Experiment 2).

As shown in FIG. 1, in Comparative Example 1 containing no surfactant, the polyol and pigment were separated over time. However, in Example 1 containing the surfactant, the polyol-dye base was well dispersed without aggregation and exhibited a uniform shape.

Therefore, in Example 1, it was confirmed that the polyol-dye base was well dispersed in the composition by using a surfactant. In this way, since Example 1 secured dispersibility by using a surfactant, various types of wax can be applied without the need to use a specific type of wax, and thus, various feelings of use can be realized.

Experimental Example 2. Evaluation of stability of polyol-dye base with or without surfactant

An experiment was conducted to evaluate the stability of the polyol-dye base according to the presence or absence of a surfactant.

Specifically, while storing the cosmetic compositions of Examples 2 to 5 and Comparative Examples 2 to 5 at 70° C. for 3 hours, it was confirmed whether the polyol-pigment base aggregated. In addition, each cosmetic composition was applied to the skin, and after erasing a part of the applied portion, the color development and degree of coloring were confirmed.

2 is a result of confirming the degree of color development and coloration of Example 3 (containing 5% by weight of polyol-color base) and Example 5 (containing 10% by weight of polyol-color base).

As a result, in the case of Comparative Examples 2 to 5 not containing a surfactant, when the polyol-dye base was included in an amount of more than 5% by weight, the base rapidly aggregated and settled. On the other hand, in the case of Examples 2 to 5 including the surfactant, even if the polyol-color base was included up to 10% by weight, the dispersion force and formulation stability were excellent.

In addition, as shown in FIG. 2, the higher the content of the polyol-dye base, the stronger the color development and coloring.

Therefore, since Examples 2 to 5 can increase the content ratio of the polyol-color base by using a surfactant, it is confirmed that the color development and coloring can be more intense than Comparative Examples 2 to 5 that do not contain a surfactant. did

Experimental Example 3. Buried test

A staining test was performed on the cosmetic composition for lip makeup of Example 1.

Specifically, when the cosmetic composition for lip makeup of Example 1 was applied to the lips and taken on the back of the hand, it was confirmed whether the color came out on the back of the hand. In addition, after erasing the cosmetic composition applied to the lips, the degree of coloring was confirmed. Comparative Example 6 was used as a control group.

3 is a smudge test result of Example 1 (experimental group) and Comparative Example 6 (control group).

As shown in FIG. 3, in Comparative Example 6 using an oil-organic pigment base, the degree of staining was severe when taken on the back of the hand, and the degree of staining was weak when erased from the lips. However, in Example 1 using the polyol-pigment base, the color hardly came out even when applied to the back of the hand, and even after erasing it from the lips, the color was colored on the lips and the vivid color development lasted for a long time.

Therefore, Example 1 was confirmed to have excellent color development and coloring strength and improved color bleeding resistance because it does not smear on the back of the hand or mask even after application to the lips, and vivid color development can last for a long time by being colored on the lips. In particular, in Example 1, as friction is applied after application, the polyol-pigment base moves toward the lips and the transparent oil moves outward, and the pigment is colored on the lips and an oil coating film is formed on the outside so that the pigment does not stick to the outside.
