Abstract
Provided is an oil-based cosmetic comprising a siliconized polysaccharide compound, silicone emulsifier, organic modified clay mineral, carbonic acid ester, and wax. According to the present invention, a spinnable oil-based composition having exceedingly excellent adherability can be obtained by using a specific siliconized polysaccharide compound, silicone emulsifier, organic modified clay mineral, carbon dioxide ester, and wax, and if this composition is used in an eyelash cosmetic material, it is possible to obtain an eyelash cosmetic material that has excellent adherability, has an excellent long-lash effect without adding fibers, and is capable of imparting a natural finished look.
