Abstract:
The present invention is a cosmetic characterized by containing at least one cyclic silicone which is represented by general formula (1) and has a boiling point of 205 to 255°C and a viscosity of less than 5 mm2/s (25°C). Thus, a cosmetic is provided, which has a light feel upon application, good spreadability and excellent water repellency, can be formed into a uniform cosmetic film, can exhibit desired volatility and a desired feel during use, and can exhibit excellent long-term stability and excellent make-up sustainability even when an oily agent such as a silicone, a hydrocarbon oil and an ester, an organic ultraviolet ray absorber or an oily component that is solid at 25°C, which has been used in cosmetics, is added to the cosmetic. (In the formula, R1 represents a monovalent hydrocarbon group having 2 or 3 carbon atoms; R2, R3, R4, R5 and R6 independently represent a monovalent hydrocarbon group having 1 to 3 carbon atoms; and a represents a positive integer satisfying the following formula 0 < a < 4 and b and c independently represent a numeral of 0 to 3, provided that (a + b + c) ≤ 4.)
