Description

WATER-DROP SOLID TYPE COSMETIC COMPOSITION IN THE FORM OF WATER-IN-OIL EMULSION OF SILICONE-FREE AND PEG-FREE, AND PREPARATION METHOD OF THE SAME}

The present invention relates to a silicone-free and sebum-free water drop solid type water-in-oil cosmetic composition and a method for manufacturing the same.

When the cosmetic composition of the water drop type is applied to the skin, the moisture in the cosmetic composition is released to the outside by shearing force to form water droplets on the skin, and these water droplets replenish moisture on the skin. And a cooling feeling. As the water replenishment power is better than the general cosmetic composition and the retention power is excellent, interest in a water drop type cosmetic composition is increasing.

For example, in the Republic of Korea Patent Publication No. 10-2018-0076180 as a silicone water-in-oil emulsified cosmetic composition comprising a silicone oil portion and a water portion, carbon dioxide generating capsules and dimethicone / page 10/15 cross polymer and page 10 Disclosed is a water drop silicone heavy water emulsifying cosmetic composition comprising a mixed surfactant of dimethicone.

Looking at Table 9, it can be seen that according to the present embodiment, it is possible to implement a solid formulation of balm type having a smooth surface.

(2) Water drop evaluation

Water drop formation of the water-in-oil cosmetic compositions of Examples and Comparative Examples was evaluated, and the results are shown in Table 10.

Whether or not a water drop was formed was determined by sparing a suitable amount of the water-in-oil cosmetic composition of Examples and Comparative Examples on the back of the hand with a spatula, and when water droplets were formed, it was determined that a water drop was formed. In Table 10, when a water drop (droplet formation on the skin surface) was formed, it was denoted by ○, and a water drop was not formed by ×.

Looking at Table 10, it can be seen that a water drop is formed according to the present embodiment.

Experimental Example 3: Skin moisturizing and cooling feeling evaluation

(1) skin moisturizing

Table 11 shows the results of skin moisturizing evaluation of the water-in-oil cosmetic compositions of Examples and Comparative Examples.

For skin moisturizing, Corneometer CM825 equipment (capacity: 100-240 V AC, 0.3 A, 50-60 Hz, measurable area: 49 mm ² , accuracy: 3%) samples on the skin (water-in-oil cosmetic of Examples and Comparative Examples) After measuring the capacitance before and after applying the composition), it was evaluated through the degree of increase in the capacitance.

First, before performing the test, the test site (internal cuff) was washed thoroughly with running water. At this time, products containing moisturizing ingredients and strong cleaning ingredients were not used. Thereafter, the water on the test site was lightly removed, dried for about 20 to 30 minutes, and a square of 2.0 cm x 2.0 cm was marked on the test site.

Before applying the sample to the test site, the capacitance was measured 5 times with a corneometer, and the average value of 3 measurements excluding the lowest and highest values was obtained.

Thereafter, after applying and absorbing a certain amount of the water-in-oil cosmetic composition of Example 1 in a square mark on the test site, after about 30 minutes, the capacitance was measured with a corneometer to obtain the average value in the same manner as above. It is shown in Table 11.

According to the same method as in Example 1, the average capacitance values of Example 2 and Comparative Examples 1 to 16 were measured, and the results are shown in Table 11. At this time, the average values of the electrostatic capacity of the test site were 35.5 to 36.0 at all times before the samples were applied in Examples 1 to 2 and Comparative Examples 1 to 16.

Average capacitance (A.U.) Average capacitance (A.U.) Example 1 46.80 Comparative Example 8 38.63 Example 2 48.34 Comparative Example 9 39.84 Comparative Example 1 41.06 Comparative Example 10 40.23 Comparative Example 2 42.48 Comparative Example 11 40.98 Comparative Example 3 40.57 Comparative Example 12 44.27 Comparative Example 4 40.94 Comparative Example 13 38.47 Comparative Example 5 41.06 Comparative Example 14 39.65 Comparative Example 6 39.85 Comparative Example 15 45.29 Comparative Example 7 39.77 Comparative Example 16 42.14

Looking at Table 11, it can be seen that the average value of the electrostatic capacity after applying the cosmetic compositions of Examples 1 to 2 and Comparative Examples 1 to 16 was higher than the average of the electrostatic capacity before the application of the sample to the test site. Since is proportional to each other, this means that the amount of moisture in the skin increases, and it can be seen that the skin moisturization is improved.

Particularly, according to this embodiment, it can be seen that the average value of the electrostatic capacity is significantly increased by 10 or more, and it can be seen that the effect of improving the skin moisturizing effect is excellent.

(2) Cooling feeling

Skin cooling feelings of Examples and Comparative Examples were evaluated and are shown in Table 12.

After applying the water-in-oil type cosmetic composition of Example 1 to 10 women in their 20s and 30s to the skin (inner cuff), and then immediately evaluating the skin cooling feeling of 0 to 5 points, the average value is indicated. 12. At this time, the closer to 5 points, the stronger the cooling feeling of the skin.

Skin cooling feelings of Example 2 and Comparative Examples 1 to 16 were evaluated in the same manner as in Example 1 and are shown in Table 12.

Skin cooling feeling Skin cooling feeling Example 1 0.5 Comparative Example 8 0.4 Example 2 3.9 Comparative Example 9 0.3 Comparative Example 1 0.4 Comparative Example 10 0.4 Comparative Example 2 0.4 Comparative Example 11 0.3 Comparative Example 3 0.3 Comparative Example 12 0.4 Comparative Example 4 0.2 Comparative Example 13 0.1 Comparative Example 5 0.3 Comparative Example 14 0.4 Comparative Example 6 0.2 Comparative Example 15 1.1 Comparative Example 7 0.3 Comparative Example 16 3.6

Looking at Table 12, it can be seen that when the phase change wax is included, the skin cooling feeling is significantly improved.

In more detail, when comparing Example 2, Comparative Example 15 and Comparative Example 16, it can be seen that, in the case of Example 2, which includes a phase change wax, and contains it in an amount of 0.01 to 10% by weight, the cooling effect is significantly improved.
