Zusammenfassung: | To provide cosmetic compositions that can provide excellent viscosity stability and a refreshing feel, even when containing inorganic powders that include metals, metal oxides, or hydroxides.SOLUTION: A cosmetic composition according to the present invention contains components (a) and (b). Component (a) is a nonionic polyamino acid derivative represented by general formula (1), and component (b) is an inorganic powder containing metals, metal oxides, or hydroxides. (In the formula, R1 represents a hydrocarbon group with 3 to 18 carbon atoms, R2 represents a group selected from hydroxyalkyls with 2 to 5 carbon atoms, methoxyalkyls with 3 to 6 carbon atoms, and ethoxyalkyls with 4 to 7 carbon atoms. n/m=40/60-60/40. (n+m)/l=80/20-100/0.)SELECTED DRAWING: None
【課題】金属、金属酸化物または水酸化物からなる無機粉体を含んでも、優れた粘度安定性とさっぱりとした触感とを同時に備える化粧料組成物を提供する。【解決手段】本発明の化粧料組成物は、成分(a)と成分(b)とを含有する。前記成分(a)が、下記一般式(1)で表される非イオン性ポリアミノ酸誘導体であり、前記成分(b)が、金属、金属酸化物または水酸化物からなる無機粉体である。TIFF2024071160000010.tif43170(式中、R1は炭素原子数3~18の炭化水素基を示し、R2は炭素原子数2~5のヒドロキシアルキル基、炭素原子数3~6のメトキシアルキル基、及び炭素原子数4~7のエトキシアルキル基からなる群から選択される基を示す。n/m=40/60~60/40。(n+m)/l=80/20~100/0。)【選択図】なし |
