Abstract: A lip cosmetic applicator device (1) including an applicator (2) for applying a cosmetic (4) to a lip and a receptacle (3) for containing the cosmetic (4). The applicator (2) is withdrawable from and insertable into the receptacle through a neck (33) of the receptacle (3). The applicator (2) includes a stem (22) and an applying portion (21) connected to one end of the stem (22). The applying portion (21) is a flattened shape and has an applying side (21A) for applying the cosmetic (4). When viewed from the front, the applying portion (21) has a widest part (21E) and gradually decreases in width from the widest part (21E) to a tip thereof. The applying side (21A) of the applying portion (21) is a concave surface having a concavity (21C) in a center thereof.

Abstract: This cosmetic application device (1) includes an application tool (2) and a container (3), the application tool (2) being insertable into and removable from the container (3) through an opening (33) of the container (3). When the application tool (2) is tilted in a state where the fixation between the lid body (23) of the application tool (2) and the mouth/neck section (32) of the container (3) has been released and the lower end section (23d) of the lid body (23) is located at a position within the height-wise length of the mouth/neck section (32), the front end of the application section (21) of the application tool (2) is made to contact an inner wall in the vicinity of the bottom section of the containing section (31) of the container (3).

Abstract: Abstract Provided is an oil-based cosmetic preparation which retains a smooth feel. Provided is an oil-based cosmetic preparation containing the following components (A), (B), and (C): (A) a cellulose derivative having a cellulose skeleton in a main chain, in which 67 mol % or more in total hydroxyl groups are substituted with a group —O-M-R, wherein M represents CH2 or a carbonyl group C?O, and R represents a straight or branched alkyl or alkenyl group having 3 to 40 carbon atoms; (B) an ester oil which is liquid at 25° C.; and (C) a hydrocarbon oil which is liquid at 25° C., in which a weight ratio (B)/(C) of the component (B) to the component (C) is 8/1 to 1/4.
