Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a cosmetic having a light touch feeling, having extension property, excellent in water repellent property, having uniform cosmetic film, capable of achieving desired volatility or use feeling, the cosmetic capable of achieving excellent temporal stability and cosmetic long-lasting, even when a silicone, various kinds of oil solutions such as hydrocarbon oil and ester, an organic ultraviolet absorber or an oily component in a solid state at 25°C.

SOLUTION: There is provided the cosmetic expressed by the following formula (1), comprising one or two or more kinds of cyclic silicone having a boiling point of 205-255°C, and viscosity of less than 5 mm2/s (25°C). (In the chemical formula 1, R1 is a univalent hydrocarbon group having a carbon number of 2 or 3, R2, R3, R4, R5 and R6 are respectively independently a univalent hydrocarbon group having a carbon number of 1-3, a is a positive number satisfying 0<a<4, b and c are respectively independently a number of 0-3, satisfying (a+b+c)≤4.)
