Description

The present invention relates to a powder surface-coated with a specific bi-terminal reactive diorganopolysiloxane and a specific amino group-containing silane compound, and a powder cosmetic containing a specific dextrin fatty acid ester. Is related to powder cosmetics having high adhesion and less likely to cause twisting of the cosmetic film due to facial expressions and eyelid movements.

Powder cosmetics are formulations used in make-up cosmetics such as eye shadows, foundations, white powders, cheeks, and eyebrows, and body powders. Especially in make-up cosmetics, the function of long-lasting makeup, which maintains the state immediately after applying makeup over time, is a very important quality. With regard to makeup loss, the phenomenon that the makeup film shines oily due to sweat and sebum secreted from the skin (so-called shine), and the phenomenon that the brightness decreases and the hue changes due to the powder getting wet with sweat and sebum (so-called shine). Dullness), a phenomenon in which the cosmetic film is localized in wrinkles and pores due to movement of facial expressions (so-called twisting / falling pores).
Further, as an important quality when a make-up cosmetic such as eye shadow is applied to the skin, a product having excellent spreadability and a uniform cosmetic film is required.
Therefore, in recent years, various surface-treated powders have been developed to improve the spread and spread during application and the long-lasting makeup. For example, silicone resin is used to improve the soft and moist feeling and smooth spread and spread. (For example, Patent Document 1) and a technique for using a powder treated with an amino acid-modified organopolysiloxane having a high affinity for the skin (for example, Patent Document 2). ) Etc. have been proposed. Further, as a surface-treated powder having a moist feeling, a smooth feel and excellent adhesion to the skin, a powder surface-treated with a silicone gel (for example, Patent Document 3) has been proposed.

However, although the technique of Patent Document 1 provides a moist feeling of use and smooth spread and spread, the adhesion to the skin is not sufficient, and the technique of Patent Document 2 provides a light spread and spread and adhesion to the skin. However, the moist feeling and long-lasting makeup were not sufficient. Further, although the technique of Patent Document 3 is excellent in feel and makeup retention, it is not possible to obtain a sufficient makeup-sustaining effect on makeup retention, especially on the twisting of the makeup film when applied to the eyes and mouth where there is a lot of movement. There was a case. For this reason, there has been a demand for the development of powder cosmetics which are excellent in smooth spread and moist feeling, and also have excellent adhesion and makeup lasting effect without the cosmetic film being twisted due to facial expressions and eyelid movements.

In view of the above situation, as a result of diligent research, the present inventors have conducted a surface-coated powder with a specific two-terminal reactive diorganopolysiloxane, a specific amino group-containing silane compound, and a specific dextrin fatty acid ester. By combining with, the powder having a relatively large amount of oil absorption efficiently retains the dextrin fatty acid ester having high affinity and adhesion to the skin on the powder surface, so that the powder has a moist feeling. The present invention has been completed by finding that the cosmetic film is not twisted due to facial expressions and eye movements without impairing the smooth spread and spread, and that the adhesiveness and the effect of sustaining makeup are excellent.
