JP6096507B2 - Oil-based solid cosmetics with protrusions - Google Patents

Description

The present invention relates to an oily solid cosmetic having a convex portion. Specifically, the present invention relates to an oily solid cosmetic material having convex portions that are patterns, characters, and the like and having a visual impact. More specifically, the present invention relates to an oily solid cosmetic in which the properties such as the color tone and touch of the convex portion are different from those of the convex portion, and the texture of the convex portion is more prominent.

Conventionally, regarding solid powder cosmetics such as eye shadows and foundations, those having an uneven pattern on the exposed surface are known. As one method for forming such a pattern, for example, Patent Document 1 discloses an elastic type in which a pattern is engraved in an uneven shape after the surface of a powder cosmetic filled in a decorative dish is covered with thin paper. A method for producing a solid cosmetic product for compression molding is disclosed. As another method, a method of forming an uneven pattern on the surface by partially peeling the surface of the solid cosmetic formed by compression molding with a laser or the like is also known.

The decoration of oily solid cosmetics includes spraying of pearl agents, uneven patterns, etc., but there is an inconvenience that it is difficult to transfer a beautiful pattern if a complicated pattern is to be applied. This is because oily solid cosmetics are characterized in that their surfaces are liable to collapse and are also sticky due to their oiliness.

Further, it is effective to make the convex pattern more accentuated, but it is effective to make the color tone etc. different from that of the other part, but it is difficult with the currently known technology.
