Description

Makeup cosmetic composition comprising a lamella structure

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

Ceramide occupies about 40% or more of the keratinocyte lipids constituting the stratum corneum of the skin and is an essential ingredient for the formation or function of the stratum corneum, and has excellent moisturizing effect and barrier function. However, ceramides are poorly soluble and are used in small amounts in cosmetic formulations, and in this case, the particle size of the formulation is reduced and gelation occurs.

In order to solve this problem, the encapsulated ceramide may be used due to the large amount of encapsulating agent, and thus the content of the encapsulating agent of the saccharide-based or polymer-based encapsulation may be impaired.

Thus, the multi-layer lamellar liquid crystal stabilizes the surface energy in the state of raising the particle size in advance to prevent gelation of the ceramide by the coalescence of the particles. At this time, if you put the powder for the makeup effect there was a problem that the particles become unstable.

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

1) An oily solution was prepared at 75 ° C. according to the composition ratio of Table 2. As pseudo ceramides, it was intended to include hydroxypropylbispalmitamide M (Pc104) and hydroxypropylbispalmitamide M (AcP102).

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 mixed by stirring with a homomixer.

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

5) After cooling to 30 ℃ 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, Example 1-4 and Comparative Example 1-5 were each taken in 10g each, 4 ° C. low temperature thermostat, 30 ° C. thermostat, 45 ° C. high temperature thermostat, -10 ° C. to After placing the samples in a cycle chamber circulating at 45 ℃ for 24 hours, the stability of the formulation was observed by observing changes in the formulations, and the results are shown in Tables 3 and 4 below.

As can be seen from the results of Table 3, Comparative Example 1 was confirmed that the emulsion is not stable because the multilayer lamellar structure is broken by the uncoated (untreated) inorganic powder, it was confirmed that the stability is poor, coated with a hydrophobic alkylsilane In Comparative Example 2, the formulation itself was not formed while developing in preparation. In Examples 1 and 2 coated with hydrophilic cellulose and silica, multilayer 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 making the multilayer lamellar liquid crystal by maintaining the manufacturing method at about 52 ° C. for about 35 minutes. In Comparative Example 3, the multilayer lamellar structure formed by the inorganic powder without surface treatment was broken, and the particle size was too small, resulting in gelation at 45 ° C., thereby degrading its value as a product. In Comparative Example 4, an inorganic powder coated with a hydrophobic alkylsilane was added after the oil-in-water emulsification was prepared, so that dispersion was not uniform. On the contrary, in Examples 3 and 4 coated with hydrophilic cellulose and silica, the multilayer lamellar liquid crystal formed was maintained as it is and was stable at 45 ° C. for 6 months. This indicates that the use of an inorganic powder surface-treated with a hydrophilic material in a composition containing pseudoceramide has an excellent effect in preventing gelation of pseudoceramide while maintaining a multilayer lamellar liquid crystal.

Comparative Example 5 was stable without gelation because no ceramide was contained.

Test Example 2 Evaluation of Skin Moisturizing Sustainability

In order to find out the moisturizing sustainability of the skin when applying it once, the makeup cosmetic composition of Examples 3, 4 and Comparative Example 5 was applied to 80 adult men and women in their 30s and 40s who complain of dryness or dry skin. After application to the inside, the moisture content of the skin was measured using a corneometer (CM820 courage Khazaka electronic GmbH, Germany) for 24 hours. Before the start of the application, the skin moisture content was measured in advance using a conniometer at constant temperature and humidity conditions (24 ° C., 40% humidity) as the basic value, and immediately after application, the change after 2 hours, 4 hours, and 8 hours was measured. The results are shown in Table 5 below.

<Corneometer measurement method>

Principle: Moisture is measured by measuring the amount of moisture in the skin's epidermis using a sensor and quantifying the amount of moisture.

1) The Koniometer probe was placed on the skin area to be measured.

2) When the probe is pressed on the skin, the electrical conductivity of the skin through the sensor is numerically displayed on the screen.

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

Test substance Skin moisture content (%) Before application Immediately after application 1 hour later 4 hours later 8 hours later Example 3 36 51 45 44 39 Example 4 34 50 47 45 40 Comparative Example 5 36 45 39 33 32

In the results of Table 5, the makeup cosmetic composition of Examples 3, 4 containing ceramides according to the present invention increased the skin moisture content immediately after application than Comparative Example 5 containing no ceramides, increased skin moisturizing power 8 It was confirmed that it lasted more than an hour.

In addition, at the end of the test, the test subjects were surveyed about the effect of improving the dry skin after using each makeup cosmetic composition, and the average value of the evaluated values (five-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: slightly effective 3 points: normal 2 points: almost ineffective 1 point: no effect

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