[0003]

According to the above-mentioned technique of blending an oil agent or wax having a high tackiness, an improvement in the persistence of the makeup can be recognized due to an increase in the adhesion to the skin, but the freshness and smoothness of the makeup are improved. In some cases, the spread was worse. In addition, in the technique of blending a film forming agent such as a silicone resin, the decorative film becomes strong and excellent cosmetic durability can be obtained, but on the other hand, the decorative film is too strong, causing a sense of discomfort such as a tight feeling. In some cases, a feeling of burden on the skin was felt.
