Description

Pearl cosmetic composition, coating method of application of pearl cosmetic composition and cosmetic product manufactured using the same The present invention relates to a pearl cosmetic composition, specifically a pearl cosmetic composition capable of easily forming a pattern layer provided on a base powder layer by an electrostatic printing method, a method for applying a pearl cosmetic composition, and a cosmetic product manufactured using the same. Powder cosmetics for makeup, such as powder compacts, blush, highlighters, and eyeshadows, are generally manufactured by compression molding powder. Since compressed powder can break somewhat easily due to external impact, a design that ensures stability is required. In particular, powders containing pearls have the problem of being relatively more susceptible to external impact. Recently, a method has been proposed to form a pattern layer containing pearls by attaching a cosmetic composition containing pearls onto a base powder in order to increase the commercial value of compressed powder. However, in the case of conventional methods, there is a problem in that ink is sprayed onto unnecessary areas in addition to the intended pattern, resulting in a slight decrease in the clarity of the pattern layer. Therefore, there is a need to develop a pearl cosmetic composition that is stable against external shocks and facilitates the formation of desired patterns. FIG. 1 is a schematic diagram of a method for applying a pearl cosmetic composition according to the present invention. Figure 2 is a diagram illustrating a method for evaluating the pearl coating quality of a pearl cosmetic composition. Figure 3 shows the appearance of the pearl pattern used in the pearl coating quality evaluation method. Figure 4 shows the appearance (pearl coating) of an eyeshadow prepared with a pearl cosmetic composition (example) and a comparative example according to the present invention. Figure 5 is a comparison result of the pearl coating quality evaluation of the pearl cosmetic composition (Example) and comparative example according to the present invention. Figure 6 shows the appearance (pearl application) of an eyeshadow made with a pearl cosmetic composition containing different types of oils. Figure 7 is a comparison result of the pearl application quality evaluation of pearl cosmetics containing different types of oils. Figure 8 shows the appearance (pearl application) of an eyeshadow prepared with a pearl cosmetic composition containing different oil contents. Figure 9 is a comparison result of the quality evaluation of pearl cosmetic pearls containing different oil contents. The present invention will be explained in more detail below with reference to examples. However, these examples are intended to illustrate the invention and should not be interpreted as limiting the scope of the invention. Pearl cosmetic composition One aspect of the present invention relates to a pearl cosmetic composition comprising, based on 100 weight% of the total, 95.0 to 99.5 weight% of a plate-shaped pearl pigment and 0.5 to 5.0 weight% of a volatile oil. Specifically, the pearl cosmetic composition may comprise 97.0 to 99.0 weight% of a plate-shaped pearl pigment and 1.0 to 3.0 weight% of a volatile oil. In one embodiment of the present invention, the pearl cosmetic composition may be used to form a pattern layer provided on a base powder layer by an electrostatic printing method. The pearl cosmetic composition according to the present invention includes plate-shaped pearl pigments and volatile oils within the above ranges, thereby being optimized for electrostatic printing methods, allowing for the easy production of a clear pattern layer, and has the advantage of being stable against external impacts. Plate-shaped pearl pigment The pearl cosmetic composition according to the present invention comprises 95.0 to 99.5 weight percent of plate-shaped pearl pigment based on 100 weight percent of the total. Preferably, the pearl cosmetic composition may comprise 97.0 to 99.0 weight% of plate-shaped pearl pigment, more preferably 97.5 to 99.0 weight%, even more preferably 98.0 to 99.0 weight%, and most preferably 98.3 to 98.5 weight%. When the above plate-shaped pearl pigment is included within the above range, it is desirable not only to have excellent aesthetics, but also to form a pattern layer that is easy to apply and stable against external impacts with the pearl cosmetic composition to be described later. The above plate-shaped pearl pigment has the advantage of providing stronger gloss and reflection effects because it has a relatively larger surface area for reflecting light compared to spherical pigments. In addition, since it has the advantage of adhering better to the skin as well as to the base powder layer described later and being distributed more uniformly, the present invention is characterized by including the plate-shaped pearl pigment within the above range.
