Abstract
Description
Technical Field
[0001] The present invention relates to an oil-based solid cosmetic.
Background Art
[0002] Many oil-based solid cosmetics with a matte finish that suppresses gloss have been developed, containing a large amount of powder to eliminate the gloss of the oil agent. However, there are problems such as the weight of spreading due to the powder, the powdery feeling and dryness affecting the usability, and the decrease in the fluidity of the bulk during filling, resulting in poor moldability. On the other hand, in the market, cosmetics that do not contain synthetic resin powder are preferred from the perspective of environmental consideration. There is a demand for the development of an oil-based solid cosmetic that realizes a matte finish with suppressed gloss, good moldability, and good usability without containing synthetic resin powder. So far, oil-based cosmetics containing a large amount of powder have been developed. For example, by blending two or more types of powders with different shapes in a specific amount, containing an elastomer, a specific amount of non-volatile oil, and a specific amount of wax, and making the volatile oil content not contain or be 1% by mass or less, a technique has been known that realizes a matte texture coating film finish with suppressed gloss and reduced stickiness (see, for example, Patent Document 1). In addition, there is a technique for a lip cosmetic with a matte texture that has good spreading, can be uniformly applied, has no sticky feeling, and has good usability by containing a specific amount of silica aerogel and a specific amount of pyrrolidone carboxylic acid ester (see, for example, Patent Document 2).
