Description

A peel-off type makeup cosmetic composition comprising polyurethane and ethanol}

It relates to a peel-off type color cosmetic composition comprising polyurethane, ethanol and a colorant.

In general, in the case of a cosmetic composition that forms a film on the skin, including a film-forming agent or a thickener, it has excellent adhesion, but the feeling of use is stiff, there is difficulty in removing the film from the skin, and there is a feeling of tightening the skin like a conventional pack. It is difficult to use for a long time.

Accordingly, it is necessary to develop a product that reduces skin tightening or stiffness during use while maintaining skin adhesion, adheres flexibly even after forming a film like a band, can be used with a film formed for a long time, and can be easily removed when finally removed. I did.

Under this background, the present inventors have overcome the shortcomings of the peel-off type makeup composition, thereby improving the feeling of use and completing a cosmetic composition that is convenient to remove after use.

It will be described in more detail through the following examples. However, these examples are for illustrative purposes only, and the scope of the present invention is not limited to these examples.

Examples 1 to 3, and Comparative Examples 1 to 3. Preparation of cosmetic composition

In order to prepare a band-type color cosmetic composition comprising polyurethane, the components of the A phase were first mixed with the components (% by weight) of Table 1 below, and then the components of the B phase were added and completely dispersed. Thereafter, the cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 were prepared by adding and mixing phase C. Specifically, xanthan gum and cellulose gum were used as the thickener. Polyvinyl alcohol was used as the film forming agent. Titanium dioxide, iron oxide, and mica were used as the colorant.

As a result, the cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 of the band type were prepared.

Experimental Example 1. Visual evaluation of cosmetic composition

Visual evaluation of the cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 was performed. Specifically, a visual evaluation of the flexibility, water repellency and stability of the composition was performed. The flexibility was evaluated on the basis of maintaining the original state flexibly without breaking, dropping, or clogging when the contents were applied to the wrist and then folded and unfolded repeatedly. The water-repellent power was evaluated by observing the degree of endurance by friction in flowing water after applying a certain amount. The stability was determined by whether or not the colorant precipitated while the contents were stored at room temperature for 1 month, whether or not to separate and whether to remix.

Item Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 flexibility Very good Very good Very good weakness Great Great Water repellency Great Great Great weakness usually usually stability Great weakness Great Great Great Great

As a result, as shown in Fig. 1 and Table 2, compared to the cosmetic composition of Comparative Example 1 that does not contain polyurethane, the cosmetic compositions of Examples 1 to 3 and Comparative Examples 2 and 3 containing polyurethane It showed more improved effect on flexibility and water repellency.

In addition, the composition of Example 2 that did not contain a thickener exhibited a negative effect because it could not impart the stability of the colorant.

In particular, compared to the composition of Comparative Example 1 that does not contain polyurethane and contains a high-concentration film-forming agent as a film-forming agent, the composition of Example 3 that contains polyurethane and does not contain a film-forming agent is flexible. , Showed excellent effects in all evaluations of water repellency and stability. That is, it was confirmed that the flexibility and water repellency of the cosmetic composition can be improved by including polyurethane, regardless of whether or not the film forming agent is included.

Experimental Example 2. Sensory evaluation of cosmetic composition

Sensory evaluation of the cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 was performed. Specifically, sensory evaluation of skin tightening, drying speed, stiffness, adhesion, persistence, irritation level, and removal level of the composition was performed on 12 panelists between 24 and 41 years of age. Specifically, the irritation level was compared to whether there was tingling during application and whether irritation was generated on the skin after removal through the difference in skin color. The removal level was individually evaluated to see if it was neat and easily removable.

As a result, as shown in Table 3, compared to the cosmetic composition of Comparative Example 1 that does not contain polyurethane, the cosmetic compositions of Examples 1 to 3 and Comparative Examples 2 and 3 containing polyurethane are skin tightening and Since the stiffness was felt weak, it was confirmed that it showed a more excellent feeling of use.

Compared with the cosmetic composition of Comparative Example 2 that does not contain ethanol in the C phase, it was confirmed that the cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 and 3 containing ethanol in the C phase have excellent drying speed.

It was confirmed that the cosmetic composition of Example 3, which contained ethanol in phase C, but did not contain a film-forming agent, and the cosmetic composition of Comparative Example 2, which contained the film-forming agent but did not contain ethanol in the C phase, showed weak adhesion. . From the above results, it was confirmed that if the film forming agent and ethanol were insufficient, sufficient adhesion could not be exhibited.

Compared to the cosmetic composition of Comparative Example 1 not containing polyurethane and the composition of Comparative Example 2 not containing ethanol in C phase, the compositions of Examples 1 to 3, and Comparative Example 3 containing ethanol and ethanol in the C phase Indicates an improved level of persistence, it was confirmed that the level of stimulation was weak and the level of removal was excellent. However, it was confirmed that the composition of Comparative Example 3 containing a high concentration of ethanol had a high level of stimulation.

From the above results, the color cosmetic composition contains polyurethane and ethanol appropriately, so that it stably contains a colorant, but has a low level of stiffness, skin tightening, and irritation after application to the skin, and is flexible and has a fast drying speed and excellent feet. Can indicate hydraulic power.

Therefore, the color cosmetic composition can be used for a long time because it exhibits excellent adhesion, water repellency and lasting power to the skin, and even after use, it will be possible to cleanly remove it without irritation to the skin.
