  • Cosmetic composition
    Patent number: 6228378
    Abstract: Disclosed herein is a cosmetic composition comprising carbon dioxide gas, wherein the viscosity of the cosmetic composition is 100 to 500,000 mPa.s at 25° C., and the concentration of the carbon dioxide gas in the cosmetic composition ejected from the container is kept at 60 ppm or more for 15 minutes after the ejection. The cosmetic composition has the ability to retain carbon dioxide gas therein, can sustain a blood circulation-facilitating effect, has the effect of improving dull looking skin, dark circles and uneven skin tone, and gives users a pleasant feeling upon use.
