Description

{Easily washable makeup cosmetic composition}

The present invention relates to a makeup cosmetic composition that is easily detached from the skin by water, and more specifically, contains a wax-type film forming agent that is easily hydrated in lukewarm water, and not only facilitates water washing when used alone, but also as a base makeup. When using also relates to a makeup cosmetic composition that helps to cleanse easily even with lukewarm water and is easily detached from the top of the skin to the overall makeup.

Most of the existing face makeup cosmetic compositions have excellent water resistance, but have a drawback that it is difficult to cleanse and a separate cleansing product must be used for clean face cleansing.

On the other hand, in recent years, mascara products have developed a product that can be detached with water alone using a film-forming agent made of a water-soluble polymer. However, due to the nature of the face makeup cosmetic composition, when the film-forming agent as described above is directly introduced into the formulation and applied to the skin, the polymers remain non-uniformly on the skin, which is accompanied by slumping and extreme dryness, so that the cosmetic composition functions properly. There was a problem that does not exhibit, and is not suitable for skin.

Domestic Patent Publication No. 2011-0008265

Accordingly, the present inventor discovered that it is possible to implement a makeup composition that can be easily washed with water only by introducing a wax-type film-forming agent instead of a polymer-type film-forming agent and optimizing it in a formulation, thereby completing the present invention. .

Accordingly, an object of the present invention is to provide a makeup cosmetic composition that can be easily detached by water.

In order to achieve the above object, the present invention provides a makeup cosmetic composition that is easy to clean, including a wax-type film-forming agent.

The composition of the present invention has an increased wash-off property, so even if only water is used without using a separate cleansing product, not only the face makeup applied thereon but also point makeup can be easily and easily removed, thereby reducing the face wash step. I can do it.

Figure 1 illustrates that the measurement of the size of the wax particles in the wax-type film-forming agent.
FIG. 2 shows a case in which a point makeup product (eyeliner, lipstick) is applied after applying Example 1 (above) and when the same makeup product is applied to bare skin without applying Example 1 (below), washed with lukewarm water. It shows the state after one.
FIG. 3 shows the state after washing with lukewarm water in the case where the foundation was applied after applying Example 1 to the artificial skin (right) and when the same foundation was applied to the bare skin without applying Example 1 (left). .

The present invention relates to a makeup cosmetic composition that can be easily washed with water alone. The composition is a wax-type film-forming agent containing nano-sized wax, instead of the polymer-type film-forming agent, which has been applied to existing point makeup products, and is optimized for the face makeup formulation. In addition to being a makeup, it is a cosmetic composition that helps to detach from the skin, even to the external point or face makeup, in response to lukewarm water when used as a makeup base, preferably an oil-in-water composition.

The composition of the present invention includes a wax-type film forming agent in order to realize the above properties. Since the wax-type film-forming agent can be easily hydrated in lukewarm water and forms a uniform film with a high moisturizing feeling on the skin, it is more suitable for face makeup formulations than PVA (polyvinyl alcohol) or acrylic film-forming polymers. It is suitable for introduction, and has excellent makeup lasting and fixing ability. Here, the wax-type film-forming agent (also referred to as a “wax film-type emulsion”) is a type of film-forming agent that forms a fine wax film on the skin. Unlike a film-forming agent in which a polymer is dispersed or emulsified, it has a fine nano size. Waxes are emulsified.

The wax in the wax-type film forming agent used in the present invention is a fine nano size having a size of about 10 nm to 700 nm, and preferably has a size of about 30 nm to 130 nm, more preferably about 50 nm to 100 nm. This is because when a wax having a size of more than 500 nm is contained, the ability to form a thin film is poor because it is not uniformly applied on the skin, and agglomeration and pushing may occur when applied on the skin.

Here, the size of the wax was measured by obtaining a mean size distribution using Nano-ZS90 (Malvern Instruments Ltd.) by hydrating the wax-like film-forming agent in water to obtain an average value. The measurement results are shown in FIG. 1 as an example of the size measurement.

The wax used in the present invention is preferably contained in an amount of 10.00 to 50.0% by weight relative to the total weight of the waxy film-forming agent in terms of film formation and cosmetic effects, and preferably contained in an amount of 35.00% by weight. . Examples of waxes that can be used include helianthus anus (sunflower) seed wax, copernicia cerifera (carnauba) wax, beads wax, sera alba wax, ozokerite wax, polyethylene wax, etc. It is not limited.

In addition, since the wax-type film-forming agent used in the present invention is in the form of an emulsion, it includes an emulsifier capable of forming an emulsion with water. As the emulsifier, polysorbate-based, cetoleth-based, behenes-based, sorbitan-based emulsifiers, etc. may be used, but are not limited thereto. In the present invention, the emulsifier may be contained in an amount of 0.01 to 20% by weight based on the total weight of the waxy film-forming agent.

The wax-type film-forming agent of the present invention may be contained in an amount of 0.01 to 30% by weight based on the total weight of the composition. Preferably it may contain 0.01 to 10% by weight. It is because the effect of forming the film film is insignificant when it is less than 0.01% by weight, and when it exceeds 30% by weight, it can have a feeling of tightness and dryness.

In addition, the composition of the present invention may further include a PVA-based film-forming agent together with the wax-type film-forming agent that can be easily hydrated in lukewarm water. By further including a PVA-based film-forming agent, the film is formed a little stronger, so that the durability is not only excellent, but also when the power to break the film is given, the wash-off property is increased so that it is possible to easily detach the face makeup as well as the point makeup. can do. The composition of the present invention may contain a PVA-based film-forming agent in an amount of 0.01 to 5.00% by weight relative to the total weight of the composition.

In addition, in order to minimize the phenomenon of drying and drying when the introduction of a film-forming agent, particularly a water-soluble film-forming agent such as a PVA-based film-forming agent, the composition of the present invention is a silicone wax, preferably stearyl dimethicone It can be additionally included, and through this, it is possible to increase the skin adhesion of the formulation and enhance the moisturizing feeling while minimizing the push-up phenomenon. The composition of the present invention may contain the silicone wax in an amount of 0.1 to 30% by weight based on the total weight of the composition.

Hereinafter, the present invention will be described in more detail through examples and test examples, but the present invention is not limited to these examples.

[Reference Example 1] Preparation of Examples and Comparative Examples

The oil-in-water compositions of Examples 1 to 3 and Comparative Examples 1 to 3 were prepared with the compositions shown in Tables 1 and 2 below. Here, Example 1 uses both a wax-type film-forming agent and a PVA-based film-forming agent, and Example 2 uses a wax-type film-forming agent. In addition, Example 3 does not use stearyl dimethicone.

In addition, Comparative Example 1 uses PVA and an acrylic film-forming agent, Comparative Example 2 does not use any film-forming agent, and Comparative Example 3 uses only an acrylic film-forming agent.

[Test Example 1] Sensory evaluation for makeup cosmetic composition

Each of the compositions according to Examples 1 and 2 and Comparative Examples 1 and 2 was applied to 20 women aged 25 to 39 years, and after 12 hours, a total of 3 of persistence, makeup desorption ability, and moisture by question Each evaluation item was evaluated. Each evaluation criterion was given a 5-point scale for each item, and the higher the effect, the higher the score. Table 2 below shows the average value of the scores.

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Make-up lasts longer than 12 hours 4.3 4.1 4.2 2 Face wash
Excellent skin desorption ability 4.8 4.2 3.8 2.1 Moist without dry 4.1 4.3 1.5 4.8

As can be seen from Table 2, Comparative Example 2, which is a typical oil-in-water makeup, has little skin desorption ability and does not easily cleanse. Because of this, it was not suitable for introduction as a face makeup.

On the other hand, Examples 1 and 2, the composition is not only excellent in skin desorption ability at the time of washing, but also has a long lasting makeup in makeup. In particular, it can be seen that by adding PVA to the wax coating emulsion, the desorption effect on the skin of the makeup cosmetic composition is doubled to help cleansing, and the durability of makeup is also increased by the addition of PVA.

[Test Example 2] Sensory evaluation for makeup cosmetic composition

When applying each of the compositions according to Examples 1 and 3 and Comparative Examples 1 to 3 to 20 women of 25 to 39 years of age, three kinds of evaluation items: no squeezing, excellent moisturizing, and no skin pulling phenomenon Was evaluated, and each evaluation criterion was given a higher score as the effect was better on a 5-point scale for each item. Table 3 shows the average value of the scores.

Example 1 Example 3 Comparative Example 1 Comparative Example 3 Smear does not occur. 4.3 3.8 2.5 1.0 Excellent moisturizing finish. 4.1 3.5 2.0 1.2 There is no skin pulling phenomenon 4.4 3.8 3.1 2.0

As can be seen from Table 3, Comparative Examples 1 and 3 were found to be unsuitable for makeup because of the extreme squeezing and skin pulling and poor finish moisturizing. On the other hand, in the case of Examples 1 and 3, it was found that there was almost no smearing and excellent moisturizing feeling, so that it was more suitable for application as a face makeup product. Through Example 1, stearyl dimethicone was not only a smearing phenomenon in the formulation. In addition, it can be seen that it also affects the moisturizing feeling.

[Test Example 3] Evaluation of ease of cleaning for makeup cosmetic composition

When applying the composition according to the present invention, the ease of cleaning was evaluated by the following method.

Example 1 was applied to part of one hand and nothing was applied to part. Next, the same makeup product (eyeliner, lipstick) was applied to the portion where Example 1 was applied and the portion not applied. Then, the degree of residue of the makeup product was observed by washing with lukewarm water. This is shown in Figure 2.

As shown in FIG. 2, it was confirmed that the upper part of the hand to which Example 1 was applied removed all of the makeup products after cleaning, while the lower part of the hand to which Example 1 was not applied remained significantly after makeup. You can.

In addition, Example 1 was applied to the right side of the artificial skin and nothing was applied to the left side. Next, the same foundation product was applied to the part to which Example 1 was applied and the part not to be applied. Then, the degree of residue of the makeup product was observed by washing with lukewarm water. This is shown in Figure 3.

As shown in FIG. 3, it can be seen that while the right part coated with Example 1 removed all of the makeup products after cleaning, the lot of makeup products remained after cleaning the left part without applying Example 1.
