Definitions
- the present invention relates to a method for producing a solid powder cosmetic.
- the solid powder cosmetics are manufactured by a dry method in which an oil powder bulk obtained by mixing powder and an oil agent is compression-molded, and a slurry is prepared by adding a volatile solvent such as water or alcohol to the oil powder bulk and filled in a container. After that, there is a wet method in which the volatile solvent is dried and removed to obtain a cosmetic. Compared with the dry method, the wet method has the characteristics that the powder and the oil agent are uniformly dispersed, and that the powder has a fine powder quality and a moist feeling.
- Volatile hydrocarbons and low-boiling alcohols are widely used as the dispersion solvent of the wet method, but in recent years, a method of using water as a solvent has been reported due to heightened environmental awareness. However, when preparing a slurry using water, it is difficult to uniformly disperse the oil agent, and the obtained product has a non-uniform dispersion state of the oil agent from the surface to the inside, which causes problems in usability and uniformity of the molded product. there were.

成型品(乾燥前)と成型品(乾燥後)の質量変化から成型品(乾燥前)の含水率を算出した。乾燥条件は、105℃3時間で行った。
成型品(乾燥前)の含水率=((成型品(乾燥前)の質量)―(成型品(乾燥後)の質量))/(成型品(乾燥前)の質量)
顕微鏡で成型品(乾燥後)の表面を観察し凹凸の高さを計測し、下記点数で評価した。
成型品(乾燥後)の表面の均一性
5点 最大0.3mm以上の凹凸が確認されない
4点 最大0.3mm以上の凹凸が確認される
3点 最大0.4mm以上の凹凸が確認される
2点 最大0.5mm以上の凹凸が確認される
1点 最大0.6mm以上の凹凸が確認される
化粧品研究従事者5名に、作製した固形粉末化粧料の[使用時の取れ量]、[パウダーの感触を感じにくい心地よい感触]について5点満点で評価してもらい、その平均点を固形粉末化粧料の点数とした。
5点 チップで使用した際の取れ量がちょうどよい(実施例4)
4点 チップで使用した際の取れ量が比較例4より多い
3点 チップで使用した際の取れ量が比較例4よりわずかに多い
2点 チップで使用した際の取れ量が比較例4よりごくわずかに多い
1点 にチップで使用した際の取れ量が少なすぎる(比較例4)
5点 非常に滑らかで心地よくパウダーの感触をほとんど感じない(実施例5)
4点 実施例5と比較してわずかに滑らかで心地良い感触が少なく、パウダーの感触をわずかに感じる
3点 実施例5と比較して滑らかで心地良い感触が少なく、パウダーの感触を感じる
2点 比較例3と比較してパウダーの感触が弱い
1点 同様にパウダーの感触がかなり強い(比較例3)
