摘要：A cosmetic composition comprising a cosmetic base selected from the groupconsisting of liquid base, paste base and powder base, a perfume ingredient, andpolyamide particles wherein the polyamide particles comprise at least either of theporous polyamide particles of the following (1) and (2) shows satisfactory shape
retention on human skin, excellent light-scattering properties to diminish abnormal lightreflection on human skin surface, and excellent oil-absorbing properties to effectivelyabsorb lipid oozing from human body when it is applied to human skin: (1) sphericalporous polyamide particles having a number average particle diameter of 1 to 30 μm, aBET specific surface area of 5 m/g or larger, a boiled linseed oil absorption of 200 mL/100g or larger, a crystallinity of 40% or higher (measured by DSC), and a ratio of volumeaverage particle diameter/number average particle diameter of 1.0 to 1.5, and (2)cylindrical or dumbbell shaped porous polyamide particles having a number averageparticle length of 0.5 to 25 μm, a ratio of particle length/particle width of 3 to 50, a BETspecific surface area of 5 m/g or larger, a boiled linseed oil absorption of 200 mL/100 gor larger, and a crystallinity of 40% or higher (measured by DSC).
