[0002]
[Prior art]
Conventionally, solid powder cosmetics such as pressed foundations have a method of blending a large amount of oil agent, a method of blending a sticky substance, a method of adhering powder and powder by the cohesive force of the powder, a pressure to compress It was molded into a solid by various techniques such as a mechanical method for increasing the viscosity. In addition, elastic powder has been used in order to improve the use of mats and other props during use and to achieve a smooth and soft feel.
[0003]
[Problems to be solved by the invention]
However, if a large amount of oil or sticky substance is added to the solid powder cosmetic, the use of tools such as sponges and mats will worsen during use, the skin will become sticky, the spread will be poor, the burden on the skin, There were sensual problems such as poor makeup persistence. On the other hand, solid cosmetics that contain only a small amount of oil to satisfy the skill and functionality of props have a problem of insufficient strength that they are weak in impact resistance and crack when transported or carried. In the method using the cohesive force of the powder, the feeling of touch is caused by the limited powder that can be used. Also, in the method of mechanically compressing at high pressure, there are limitations on the powders that can be used and the limitations on the filling container, and furthermore the impact resistance is improved, but the training on props such as sponges and mats is worsened. There was a problem that, when a powder having elasticity was blended, it could not be molded. Furthermore, in order to improve the training of props such as mats, and to achieve a smooth and soft feeling of use, when blending elastic powder, the elastic powder absorbs the compression force at the time of molding. However, there is a problem that the compression moldability is deteriorated, and as a result, the impact resistance is lowered. For this reason, development of the solid powder cosmetics which solved these problems was desired.
[0004]
[Means for Solving the Problems]
As a result of intensive studies in the above situation, the present inventor uses a combination of a specific solid oil powder and an elastic powder, so that it can be easily applied to props such as sponges and mats during use, and adheres to the skin. The present invention has been completed by finding that a solid powder cosmetic having excellent properties, smooth and soft feeling of use, and excellent moldability and impact resistance can be obtained.
