Abstract: A solid lip cosmetic provides excellent effects of being prevented from secondary adhesion and also has excellent usability, long-lasting glossiness and stability. A solid lip cosmetic is characterized by comprising (a) 25 to 50% by mass of hydrogenated polyisobutene; (b) 20 to 70% by mass of at least one methylphenylsilicone component that can be separated from the component (a) when the component (b) is mixed with the component (a) at 25° C.; (c) 1 to 20% by mass of neopentyl glycol dicaprate that serves as a compatibility modifier that can adjust the compatibility of the component (a) with the component (b); and (d) 3 to 12% by mass of a wax.
