Definitions

• the present invention relates to a cosmetic oil agent that has good compatibility with the skin, imparts a moist powdery feel, and is excellent in rinsability with water, and a cosmetic product containing the same.
• volatile oils and silicone oils have been used as texture modifiers in many products such as skin care cosmetics, emulsifying cosmetics, makeup cosmetics, sunscreen products, cleansing products, and hair care products.
• the feeling of use required for a feel improver is that the preparation absorbs quickly into the skin, suppresses the stickiness of the preparation, and has a powdery feel (a film is formed on the skin after application, resulting in a feeling of smoothness that lasts). ).
• volatile oils such as cyclomethicone, light isoparaffin, and isododecane can make preparations more readily absorbed into the skin and provide a light feeling of use. Therefore, various volatile oils have been developed.
• Patent Document 1 discloses a hydrocarbon mixture containing a hydrocarbon with 11 carbon atoms and a hydrocarbon with 13 carbon atoms.
• Patent Document 1 due to its high volatility, the volatile oil solution of Patent Document 1 is likely to evaporate water from the surface of the body, resulting in a dry, powdery feel. Furthermore, when a formulation containing a large amount of oil as a feel-improving agent is applied to the face or hands and rinsed, the poor rinsability of the oil with water also affects the formulation, making it difficult to remove the formulation sufficiently. There may be a feeling of comfort.
• Patent Document 2 it is preferably used as a cosmetic or cleansing oil for skin and hair, and has excellent volatility and has 12 to 16 carbon atoms. Paraffins containing isoparaffins and paraffins mixtures containing 2,2,4,6,6-pentamethylheptane are disclosed.
