Abstract: The present invention is an oil-based liquid cosmetic containing: 60% by mass or more of polydimethylsiloxane (A); 0.01 to 1% by mass of N-acyl-L-glutamic acid dialkylamide (B); and 0.5 to 35% by mass of a compatibilizer (C) for compatibilizing the component (A) and the component (B). The oil-based liquid cosmetic preferably has a viscosity that is measured using a B-type rotational viscometer at 25° ° C. of 5 to 100,000 mPa·s.

Abstract: An oil-based cosmetic contains, as an oily base, an oil containing a phytosterol derivative, having a refractive index at 40° C. of 1.50 or more, and being liquid at 25° C. (A) and a liquid silicone oil that is incompatible with the oil (A) at 25° C. (B). In addition to the oily base material, a separation inhibitor to suppress separation of the oil of the component (A) and the silicone oil of the component (B) (C) is preferably contained, and a powder (D) and a solid oil and/or lipophilic gelling agent (E) may also be contained. A form of the of oil-based cosmetic can be appropriately selected according to an application, and can be a liquid, paste, solid, or the like.
