Description

Cleansing cosmetic composition comprising fatty acids with lumpy cloud texture

The present invention relates to a fatty acid cleansing cosmetic composition having a glossy appearance.

Makeup cleansing products consist of a primary cleanser such as cleansing oil and water and a secondary cleanser containing a cream-type cleansing foam. Cleansing foams have been used by default.

Cream-type fatty acid soaps, commonly called cleansing foams, were first developed in the 1960s and began to come to the market. In addition to the excellent cleansing and foaming power of soaps, the cream-type fatty acid soap is a face-only product with a large amount of moisturizer. . Since the formulation of the cleansing foam is in a cream state, it has the advantage of easily obtaining abundant foam compared to a solid soap bar, and has been developed as an important cleanser for cosmetics, and is currently a gel or foam type other than a cream type. There is a variety of changes in the dosage form.

The formulation of the cleansing foam is a mixture of 12 to 18 carbon atoms (stearic acid, palmitic acid, mystic acid, lauric acid, etc.), which are known to be highly cleansing, and KOH, polyols (glycerine, polyethylene glycol 400) as neutralizing agents. , Butylene glycol, dipropylene glycol, etc.), nonionic surfactants and ionic surfactants, and the state of the foam (bubble size and size, elasticity, durability, Cleaning power, etc.), physical properties and stability are different.

Recently, the standard of selecting cosmetics by consumers is diversified, and a large portion of them is known as a new texture and usage method. Facial cleansers are also developing new formulations such as pack-to-foam, which combines the role of a pack and cleanser, and bubble foam, which contains fluorine to generate fine bubbles.

Among them, the cleansing foam obtained by neutralizing fatty acids is one of the difficult formulations to obtain a new texture. This is because it is difficult to adjust the texture due to the reaction conditions and process constraints due to the characteristics of the formulation obtained through the chemical reaction.

In addition, the constraint of low cost is that it is difficult to use expensive polymers or thickeners to make new formulations.

Accordingly, the present inventors use an acrylate / C 10-30 alkyl acrylate crosspolymer suitable for use in a fatty acid-based cleaner to overcome the above limitations, thereby producing a fatty acid cleansing foam expressing a new texture. It was confirmed that the present invention was completed.

Experimental Example 1. Appearance and sensory evaluation of the cleansing composition

As described above, the appearance and sensory evaluation were performed on the cleaning composition prepared according to Examples and Comparative Examples. The appearance is shown in FIG. Example 1-6 confirmed whether or not the formulation can be expressed in a hazy form depending on the content of the acrylate / C 10-30 alkyl acrylate crosspolymer. In Example 3-6, a formulation filled with moisture was expressed while a hazy appearance appeared prominently. On the other hand, in the case of Example 1-2, it appears that the characteristics of the formulation, which are less but whitish than those of Examples 3-6, are expressed.

In Comparative Example 1-2, even a general paste did not appear, and a thin cream that flowed out appeared. In the case of Comparative Example 4-5 agglomerates too much to facilitate a smooth mixing into a general homo mixer.

Experimental Example 2: Checking the skin moisture of the cleansing composition

The composition prepared in the above example was prepared to have a glossy appearance and excellent moisture, and to confirm this, before testing, the test site (inside of the lower chest, 2 cm × 2 cm) was washed with lukewarm water for 10 minutes. Afterwards, the skin moisture content of the test site was measured. Thereafter, after the water was applied to the test site, 2 μL of the composition prepared in Example and Comparative Example was applied to the test site and rolled 50 times, followed by washing with lukewarm water. After 10 minutes, the skin moisture of the test site was measured. The measuring instrument was a Corneometer (CK electronic, Germany).

Using the average of the three measurements, the rate of change of skin moisture content was calculated from the skin moisture content measured after applying the composition and the composition was evaluated, and compared with before use to affect the skin moisturization of the composition. The extent of the impact was confirmed.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Skin moisture level (%) 100.1 100.3 100.5 100.6 102.3 101.8 99.2 93.6 99.5 98.5 99.4

As can be seen in the results of Table 3, the application of the composition of the embodiment was found to be more moisturizing than skin loss after cleansing, the comparative example was found to have a lot of moisture loss after face wash with a change rate of 0.6 ~ 6.4%. Therefore, it can be seen that the moisture loss of the skin will be less when using the composition of the present invention.

Experimental Example 3: sensory evaluation of the cleansing composition

The new feeling of use, cleaning power, foaming power, and moisturizing feeling were evaluated for the compositions prepared through Examples 1 to 7 and Comparative Examples 1 to 5.

Sensory evaluation was performed on 13 unmarried men and women in their 20s and the results are shown in Table 3 below. The scores were 1 to 5 points (higher positive rating), and the average of 13 evaluator scores for each item.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 newness 4.5 4.7 4.9 4.9 5 5 One One One 2.1 1.8 Cleaning power 3.5 4.1 4.2 4.1 4.7 4.6 3.2 3.1 3.3 3.0 3.5 Foam 4.1 4.2 4.3 4.4 4.8 4.9 3.1 3.3 3.1 3.1 3.7

As a result of the sensory evaluation, most of the evaluators showed a positive response to the new appearance and touch when using the cosmetic composition provided through the present invention, and also obtained higher scores than the comparative example in the evaluation of cleaning power and foaming power.

On the other hand, in Comparative Example 3, there was no recognition of a new texture as a general cleansing foam formulation, and in Comparative Example 1-2 for confirming the expression of the formulation, there was an evaluation that it was difficult to use because the paste phase did not come out.

Although the preferred embodiments of the present invention have been described in detail above, the rights of the present invention are not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided.
