Abstract
(EN) 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.)
(FR) La présente invention concerne un produit cosmétique caractérisé en ce qu'il contient au moins une silicone cyclique qui est représentée par la formule générale (1) et présente un point d'ébullition de 205 à 255 °C et une viscosité inférieure à 5 mm2/s (25 °C). Ainsi, l'invention concerne un produit cosmétique offrant une sensation de légèreté lors de l'application, une bonne aptitude à l'étalement et d'excellentes propriétés hydrofuges, pouvant former un film cosmétique uniforme, présenter une volatilité souhaitée et une sensation souhaitée pendant l'utilisation, et présenter une excellente stabilité à long terme et une excellente durabilité de maquillage même lorsqu'un agent huileux tel qu'une silicone, une huile hydrocarbonée et un ester, un absorbeur de rayons ultraviolets organique ou un composant huileux solide à 25 °C, ayant été utilisé dans des produits cosmétiques, est ajouté au produit cosmétique. (Dans la formule, R1 représente un groupe hydrocarboné monovalent comprenant 2 ou 3 atomes de carbone; R2, R3, R4, R5 et R6 représentent indépendamment un groupe hydrocarboné monovalent comprenant 1 à 3 atomes de carbone; et a représente un nombre entier positif satisfaisant la formule suivante : 0 < a < 4, et b et c représentent indépendamment un nombre entier de 0 à 3, à condition que (a + b +c) ≤ 4.)
(JA) 本発明は、下記一般式(1)で表され、沸点が205~255℃の範囲にあり、且つ、粘度が5mm/s(25℃)未満である環状シリコーンを1種または2種以上含有するものであることを特徴とする化粧料である。これにより、軽い感触で、伸びが良く、撥水性に優れ、化粧膜が均一であり、所望の揮発性や使用感を達成することができ、化粧料に使用されるシリコーン、炭化水素油、及びエステル等の各種油剤、有機紫外線吸収剤、あるいは、25℃で固体状の油性成分を配合した場合においても、優れた経時安定性、化粧持続性を有する化粧料が提供される。 (式中、Rは炭素数2又は3の一価の炭化水素基であり、R、R、R、R及びRはそれぞれ独立して、炭素数1~3の一価の炭素水素基である。aは、0<a<4の正の数であり、bおよびcはそれぞれ独立して0~3の数であり、ただし(a+b+c)≦4である。)
