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.

Abstract: The present invention provides a lipstick composition which drastically improves the color development and also is superior in terms of spreadability, gloss, and long-lastingness The present invention also provides a lipstick composition with superior a shape-retaining ability without using ceresin for the shape-retaining agent. The present invention is a lipstick composition comprising (a) 3-25 mass % of one, two or more types of polyethylene wax (average molecular weight 300-700) and (b) 0.1-50 mass % of one, two or more types of liquid oil having one —OH group in the structure.
