1. In the first dissolution tank, hydrophilic components are dissolved in the first pre-set environment.

Purified water is included in the first dissolution tank, and hydrophilic components are dissolved in purified water in a predetermined first environment. Here, the hydrophilic components are butylene glycol, pentylene glycol, niacinamide, allantoin, adenosine, xanthan gum, and sodium acrylate/sodium acryloyldimethyltaurate copolymer, and the hydrophilic components are dissolved in the first dissolution tank. . At this time, a first preset environment is provided to the first melting tank. Here, the preset first environment includes a temperature of 80°C, a rotation rate of 1000 RPM as a first disperser such as a Homo Mixer and a rotation rate of 20 RPM as a second disperser such as a Paddle Mixer, and such an environment is 10 Can be served for minutes. As such a predetermined first environment is provided, the hydrophilic components are completely dissolved in the first dissolution tank.

2. In the second dissolution tank, the hydrophobic components are dissolved in the first pre-set environment.

The dissolution of the hydrophobic components proceeds in the second dissolution tank, which is separate from the first dissolution tank. Here, the hydrophobic components are isononyl isononanoate, titanium dioxide, cocoglyceride, methyl methacrylate crosspolymer, polyglyceryl-10 laurate, polyglyceryl-10 myristate, aluminum hydroxide, stearic Acid, hydroxyapatite and sorbitan isostearate, and hydrophobic components are dissolved in the second dissolution tank. The second dissolution tank provides the first environment previously set, and accordingly, the hydrophobic components are completely dissolved in the second dissolution tank.

3. Emulsify the components dissolved in each of the first and second dissolution tanks using an emulsifier.

Hydrophilic components and hydrophobic components dissolved in the first and second dissolution tanks are added to the first dissolution tank, the second dissolution tank, or a separate dissolution tank. However, since the properties are different from each other, the emulsifier is added to the dissolution tank in which both components are added. An emulsifier is added to emulsify both ingredients. The emulsification may be performed in a preset first environment, and the first disperser may provide a higher RPM (eg, 2500 RPM) in the preset first environment.

4. The fourth composition or the fifth composition is added to the emulsified ingredients in the second preset environment.

A preset second environment is provided to the components emulsified through the above process. The preset second environment includes a temperature of 35°C, which is a temperature lower than the preset first environment, and a rotation rate of 1000 RPM as the first disperser and 20 RPM as the second disperser, and this environment is provided for 1 minute. When a preset second environment is provided to the emulsified ingredients and the temperature reaches 35°C, a fourth composition or a fifth composition that enhances the effect of brightening the skin tone and improving wrinkles or enhancing the moisturizing power of the skin is added. Then stir. The composition to be added includes orange peel oil, glycerin, rosewood oil, 1,2-hexanediol, sented geranium flower oil, sodium hyaluronate, glacier water, biosaccharide gum-4, morohiya leaf extract, calendula Extract, royal jelly extract, honey extract, pearl extract, madecassoside, aloe vera leaf extract, and seed perilla extract may be included. After the fourth composition or the fifth composition is added to the emulsified ingredients, it is stirred in a second preset environment.

5. The final agitated compositions are subjected to a defoaming process.

By performing the defoaming process, the final cosmetic composition is prepared.

In order to confirm the performance of the cosmetic composition prepared through the above-described process to prevent fine dust from adsorbing to the skin, a performance test was performed under the following conditions.

The performance test was conducted on 20 adult women aged 20 to 55 (2 in their 20s, 10 in their 30s, and 8 in their 40s), and the test site where the cosmetic composition and the control were applied to the forearm of the test subject, respectively. The bay was exposed to the alternative fine dust floating chamber for 1 minute so that the substitute fine dust was adsorbed to the test site. The alternative fine dust was carbon black (Korea Carbon Black Co., Ltd., Corax N220, particle size: 20-25 nm), and 1 g was suspended in the chamber. An image of the test site was taken for the test subject exposed to the replacement fine dust for 1 minute, and an image analysis program was used to analyze the difference in pixel values for the images before and after exposure. The control group corresponds to a composition prepared without hydroxyapatite in the cosmetic composition.

As a result of analysis, the effect of preventing adsorption of fine dust of the test product compared to the control group was as follows. Here, the unit of the result is a dimensionless unit (A.U.: Arbitrary Unit), and the smaller the amount of alternative fine dust is adsorbed, the smaller the adsorbed amount, so the result value is lowered.

The improvement rate was calculated as follows.

That is, from the above results, it can be seen that the cosmetic composition has an excellent ability to prevent adsorption of fine dust by about 27% compared to the control. That is, it was confirmed that the ability to prevent fine dust adsorption was changed by about 27% depending on whether or not hydroxyapatite was included.
