Problems solved by technology

As a method, there is a method of mixing powder and pulverizing it with an atomizer and then directly adding it to cosmetic manufacturing equipment for dispersion. This method has the following disadvantages: During the manufacturing process, a lot of powder dust is generated, and it is difficult to adjust during manufacturing. color, and there are the following problems: the miniaturization and homogenization of powder particles are not good
However, it has the following disadvantages: when manufacturing the powder composition, there is a danger of operating the manufacturing equipment, and depending on the manufacturing conditions, the quality of the powder composition is not uniform, so that agglomeration occurs when using cosmetics made from the powder composition

experiment example 1

[0039] Experimental example 1. Comparison of the dispersion state of the particulate titanium dioxide powder composition by the dispersion process

[0040] For the powder composition produced by mixing powder, solvent, and additives, the dispersion process was changed, and the particle dispersion state and size were compared. Figure 1A to Figure 1C It is a microscopic enlarged photo of a powder composition dispersed under a pressure of 600bar by a high-pressure disperser after mixing particulate titanium dioxide, cyclopentasiloxane, and PEG-10 polydimethylsiloxane, figure 2 It is an enlarged photograph of a powder composition dispersed by agitation mixing (Agitation Mix) after mixing particulate titanium dioxide, cyclopentasiloxane, and PEG-10 polydimethylsiloxane.

[0041] if compare Figure 1A to Figure 1C and figure 2 , then it can be confirmed that the powder composition ( Figure 1A to Figure 1C ) powder particles are very small and dispersed by homogenization.

[0043] Experimental Example 2. Comparison of Dispersion State of Titanium Dioxide Powder Composition by Dispersion Process

[0044] Figure 4A to Figure 4C It is a microscope enlarged photo of a powder composition manufactured by using a high-pressure disperser to disperse titanium dioxide, cyclopentasiloxane, and PEG-10 polydimethylsiloxane under a pressure of 600 bar. Figure 5 is a combination of titanium dioxide and cyclopentasiloxane Microscopic magnified photo of a powder composition produced by mixing the alkanes and PEG-10 polydimethylsiloxane and then dispersing them by stirring and mixing.

[0045] if compare Figure 4A to Figure 4C and Figure 5 , then it can be confirmed that the powder composition ( Figure 4A to Figure 4C ) powder particles are very small and dispersed by homogenization.

Abstract

The invention provides a powder composition dispersed through a milling process and a method for preparing the same. The present invention provides a micronized and homogenized powder composition thatcan be included in a cosmetic composition, and by using same, a cosmetic composition which is long-lasting and has improved excellent adhesion, high coverage, softness during use, or the like can beprepared. By using the powder composition of the present invention, unevenness of skin, such as wrinkles, pores, or the like, can be effectively filled such that smooth skin can be expressed, skin canbe evenly covered without leaving a white cast, and skin adhesion is excellent.

Description

technical field [0001] The present invention relates to a method for producing a powder composition contained in a cosmetic composition and a powder composition produced by the method, specifically, to a method for improving the effect of miniaturization and homogenization of particles of a powder composition Method and powder composition produced by the method. Background technique [0002] The makeup cosmetic composition needs to be gently applied to the skin when applied, has excellent skin adhesion and covering effects, does not shine over time, and maintains excellent stability to the skin. This property is largely influenced by powders contained in cosmetics. [0003] In general, well-known emulsified or oil-dispersed make-up cosmetic compositions use various types of powders, and have various forms of adding steps and dispersing steps. As a method, there is a method of mixing powder and pulverizing it with an atomizer and then directly adding it to cosmetic manufact...
