Abstract
A cosmetic containing at least 1% by weight of hydrofluoroether having a viscosity of less than 5 mPa·s at 25° C., which is represented by the general formula (1): CnHmFl—O—CxHyFz (1) wherein n is a number of 1 to 12, m is a number of 0 to 25, l is a number of 0 to 11, m+l=2n+1, x is a number of 1 to 12, y is a number of 0 to 25, z is a number of 0 to 11, and y+z=2x+1, provided that m and y are not be simultaneously zero, and l and z are not be simultaneously zero, gives no environment disruption, is highly safe for the skin and improves the feeling in use.
