(Stearic acid), aliphatic alcohol (stearyl alcohol), hydrocarbon oil (mineral oil), ester oil (caprylic / capric triglyceride), silicone oil (dimer Chicone) and the natural oil and the first surfactant were heated to 65 占 폚. The second mixture comprising the phospholipid (lecithin) and the second surfactant was then heated to 65 占 폚.

Then, the heated first mixture and the second mixture were mixed to prepare a third mixture in which the first micelle was formed, and the third mixture was cooled to room temperature (25 캜). Polyol (1,2-hexanediol and glycerin), water and poloxamer were added to the cooled third mixture, and the mixture was pressurized at 1200 bar to form secondary micelles, thereby preparing a micelle composition having an average size of 10 μm.

Example 2 to 4

The myc shell composition was prepared in the same manner as in Example 1, except that the components and contents in the following Table 1 were used.

Comparative Example 1-4

Comparative Example 5

The same contents and components as in Example 1 of Table 1 were applied and mixed at room temperature using a stirrer to prepare a composition without micelle formation.

Test Example One. Formulation stability evaluation

To measure the stability of the micelle compositions of Examples 1 to 4 and Comparative Examples 1 to 5 with respect to the degree of discoloration, a thermostat kept constant at 45 ° C, 25 ° C, and 4 ° C, 4 and Comparative Examples 1 to 5 were put in containers for 5 weeks and stored for 4 weeks, and the degree of separation and discoloration was comparatively measured. The results are shown in Table 2 below. The degree of separation and discoloration of the product was classified into the following six grades and evaluated.

* Separation and discoloration evaluation criteria

4: Severely separated (discolored), 5: Severely separated (discolored), 2: slightly separated (discolored), 3: slightly separated (discolored)

FIG. 1 (a) shows the characteristics of the micelle composition of Example 1 of the present invention, and FIG. 1 (b) shows the characteristics of the micelle composition of Comparative Example 1 of the present invention. Referring to FIG. 1, it can be seen that, in the case of Example 1, the capsules containing the core component including the oil are solubilized and mixed in a stable form. However, in the case of Comparative Example 1, it was found to be a grayish white color, and the overall property was not smooth.

With reference to Table 2, the cosmetic compositions of Examples 1 to 4 hardly undergo discoloration and separation phenomena, but Comparative Examples 1 to 3, which contain the components of the present invention or to which different components are applied, It was found that the separation and discoloration occurred significantly in the case of Comparative Example 5 in which no organic solvent was formed.

Test Example 2. Evaluation of skin improvement effect

When the above-mentioned Examples 1 to 4 and Comparative Examples 1 to 5 were used, overall preferences such as skin moisturizing effect, skin softening effect, and flushing feeling were evaluated. Specifically, 40 women aged 15 to 30 years were allowed to use each of Examples 1 to 4 and Comparative Examples 1 to 5 by 5 persons for 2 weeks (twice a day (morning and evening)), (1: very bad → 10: very good), the skin's moisturizing, skin softening effect and feelings were evaluated for overall preference, followed by Duncan's multiple range test. As a result, the results shown in Table 3 were obtained.

Referring to Table 3, it can be seen that Examples 1 to 4 of the present invention are superior to those of Comparative Examples 1 to 5 in terms of skin moisturizing, skin softening effect and overall preference. In particular, In the case of Example 4, it was found that the overall preference such as skin moisturizing effect, skin softening effect, and skin rusting property was remarkably lowered as compared with Examples 1 to 4 above.

2 is an optical microscope photograph showing the micelle of Example 1 of the present invention. Referring to FIG. 2, it was found that spherical capsules were formed, and skin barrier improvement and moisturizing effect were excellent.

Test Example 3. Antioxidant effect measurement

Free radicals are very reactive species with unpaired electron pairs. ROS produced in vivo contains free radical species such as superoxide anion radical (O- ² ) and hydroxyl radical (OH). These radicals react with the various constituents of the skin with high reactivity, thereby damaging the various tissues present in the skin. Thus, free radicals can be a major cause of skin damage and aging. The reducing power of antioxidants that reduce such free radicals can be found by using 1,1-diphenyl-2-picryl hydrazine (DPPH). Since DPPH is a relatively stable free radical, it is an oxidizing agent widely used in experiments.

It measures the extent to which purple is removed as the sample clears the radicals. First, 0.15 ml of a solution prepared by dissolving DPPH in methanol at a concentration of 1x10 ^-4 M was put into a test tube, and 0.15 ml of each sample was added to each of the concentrations of Examples 1 to 4 and Comparative Examples 1 to 3 at 20 The absorbance was measured at 565 nm after the minute reaction. The free radical scavenging effect of each of the samples of the examples and comparative examples was determined by IC50 by calculating the concentration at which 50% of radicals were eliminated by using the following equation (1). At this time, ascorbic acid was used as a positive control group and the reaction absorbance of the solution not treated with the sample was used as a negative control group. The free radical scavenging effect of each sample was determined by calculating the concentration at which 50% of the radicals were eliminated by using Equation 1 and expressed as IC50, and the results are shown in Table 4 and FIG.

[Formula 1]

Free radical scavenging ratio (%) = [(absorbance of control group - absorbance of each sample) / absorbance of control group] × 100

division IC50 (mg / mL) Example 1 1.06 Example 2 7.47 Example 3 2.89 Example 4 0.95 Comparative Example 1 3.54 Comparative Example 2 10.54 Comparative Example 3 10.78 Positive control group 0.7

Referring to Table 4, the IC50 values of Examples 1 to 4 of the present invention were superior to those of the control group.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
