Description

Makeup cosmetic composition comprising lamellar structure

The present specification relates to a makeup cosmetic composition in which a ceramide is stabilized using an inorganic powder surface-treated with a hydrophilic coating agent.

Ceramide accounts for about 40% or more of the lipid between keratinocytes constituting the stratum corneum of the skin and is an essential component for the formation or function of the stratum corneum. It has excellent moisturizing effect and barrier function strengthening effect. However, ceramides are poorly soluble and, when contained in a large amount in a cosmetic formulation, use a smaller particle size. In this case, the stability of the formulation decreases and gelation occurs.

In order to solve this problem, when ceramide is encapsulated and used, the content that can be actually used is reduced due to a large amount of encapsulating agent, and there are disadvantages in that the saccharide-based or polymer-based encapsulating agent impairs the feeling of use.

Therefore, the multi-layered lamellar liquid crystal prevents the gelling of ceramides due to the coalescence of particles by stabilizing the surface energy in a state in which the particle size is increased in advance. At this time, there was a problem in that the particles become unstable when powder for makeup effect is added.

It is to provide a stable makeup cosmetic composition while maintaining liquid crystal by using a powder surface-treated with silica.

1) An oily solution was prepared at 75° C. according to the composition ratio in Table 2 above. As pseudoceramides, hydroxypropylbispalmitamide ME (Pc104) and hydroxypropylbis palmitamide ME (Pc102) were included.

2) A 75°C aqueous solution was prepared in a separate container.

3) The oily solution of step 1) was added to the aqueous solution of step 2), and the mixture was stirred with a homomixer.

4) After maintaining the cooling temperature at about 52° C. for about 35 minutes, the colorant was mixed and dispersed.

5) After cooling to 30° C., it was completely degassed to prepare an oil-in-water makeup cosmetic composition.

[ test example 1] Stability comparison

In order to confirm the formulation stability of the makeup cosmetic composition of the present invention, 10 g of each of Examples 1-4 and Comparative Examples 1-5 were taken, and a low-temperature thermostat at 4°C, a thermostat at 30°C, a high-temperature bath at 45°C, -10°C to After each sample was put into a cycle chamber circulating at 45° C. for 24 hours, the change in the formulation was observed to confirm the stability, and the results are shown in Tables 3 and 4 below.

As can be seen from the results of Table 3, in Comparative Example 1, it was confirmed that the multi-layered lamellar structure was broken by the uncoated (non-surface-treated) inorganic powder, and the emulsion was broken, resulting in poor stability, and coated with a hydrophobic alkylsilane. In Comparative Example 2, the formulation itself was not formed while inverted during manufacture. In Examples 1 and 2 coated with hydrophilic cellulose and silica, multi-layered lamellar liquid crystals having a particle size of 2 μm or more were formed, but showed an unstable appearance at 45° C. long-term stability.

Table 4 shows the results of dispersing the pigments by type after changing the manufacturing method and maintaining it at about 52° C. for about 35 minutes to make a multilayer lamellar liquid crystal. In Comparative Example 3, it was confirmed that the multilayered lamellar structure already formed by the non-surface-treated inorganic powder was broken, and the particle size was too small, resulting in gelation at 45° C., thereby reducing the value as a commodity. In Comparative Example 4, after the oil-in-water emulsion was prepared, the inorganic powder coated with the hydrophobic alkylsilane was added, and the dispersion was not made uniformly, so it had no value as a commodity. In contrast, in Examples 3 and 4 coated with hydrophilic cellulose and silica, the formed multi-layered lamellar liquid crystal was maintained as it is, and it was found to be stable at 45° C. for 6 months, indicating very good phase stability. This indicates that when an inorganic powder surface-treated with a hydrophilic material is used in a composition containing a pseudo-ceramide, there is an excellent effect in preventing gelation of the pseudo-ceramide while maintaining the multi-layered lamellar liquid crystal.

Comparative Example 5 did not contain ceramide and was stable without gelation.

[Test Example 2] Evaluation of skin moisturizing durability

In order to find out how long the skin moisturizes when applied once, the makeup cosmetic compositions of Examples 3, 4 and Comparative Example 5 were applied to 80 adults in their 30s and 40s who complained of dryness or who had dry skin. After it was applied to the inside, the skin moisture content was measured using a corneometer (CM820 courage Khazaka electronic GmbH, Germany) for 24 hours. The skin moisture content was measured in advance using a coniometer under constant temperature and humidity conditions (24° C., humidity 40%) before the start of application, and the change was measured immediately after application, after 2 hours, 4 hours, and 8 hours. The results are shown in Table 5 below.

<Corneometer measurement method>

Principle: The amount of moisture in the epidermis of the skin is measured using a sensor to measure the ion level of moisture, and the amount of moisture is calculated by quantifying it to measure the moisturizing power.

1) Place the coniometer probe on the skin area to be measured.

2) When the probe was pressed against the skin, the electrical conductivity of the skin was digitized through the sensor and displayed on the screen.

3) After measuring once, wipe the sensor with a tissue such as Kimwipe, then repeat the measurement by changing the measurement area.

From the results of Table 5, the makeup cosmetic compositions of Examples 3 and 4 containing ceramide according to the present invention increased the amount of skin moisture more immediately after application than Comparative Example 5 without ceramide, and the increased skin moisturizing power was 8 It was confirmed that it lasted more than an hour.

In addition, at the end of the test, a survey was conducted on the effect of improving skin dryness after using each makeup cosmetic composition to the test subjects, and the average value of the evaluated values (5-point scale) is shown in Table 6 below.

test substance Dryness improvement effect Example 3 4.5 Example 4 4.7 Comparative Example 5 3.3 <Evaluation criteria>
5 points: Very effective.
4 points: It is slightly effective.
3 points: average.
2 points|pieces: There is almost no effect.
1 point: No effect at all.

From the results of Table 5, it was confirmed that the skin dryness improvement effect of Examples 3 and 4, which is a makeup cosmetic in which ceramide was stabilized using the hydrophilic surface-treated inorganic powder according to the present invention, was superior to that of Comparative Example 5.
