The eyeliner cosmetic of the present invention for solving the problem is characterized by containing the following components (A) to (D): the water-based dispersion liquid for the water-based paint comprises (A) an alkyl acrylate/vinyl acetate copolymer dispersion (A-2) using a nonaqueous solvent (A-1) as a dispersion medium, (B) a dextrin fatty acid ester, (C) a hydrophobized surface-treated powder, and (D) a volatile oil agent.

Description

Eyeliner cosmetic

Technical Field

The present invention relates to an eyeliner cosmetic.

Background

The eyeliner is a cosmetic that emphasizes the eyes by drawing lines on the outlines of the eyes to make them look large. From the viewpoint of the method of using the cosmetic film to draw the contour of the eye, it is required to have a soft cosmetic film which is easy to draw a line smoothly without causing halation, has a film-forming property to form a dried film instantaneously, has a makeup-sustaining property to cope with bleeding caused by tear or sebum, and does not cause cracks due to continuous movement of the eyelid. In addition, since the contour of the eye is a very sensitive part, it is also important to simply remove the cosmetic film without strong wiping (ease of removal).

The eyeliner cosmetic is of an oil type or a water type. Here, the oil type means a nonaqueous or W/O type eyeliner cosmetic, and the water type means O/W or eyeliner composed of only water-soluble components. In general, the oil type is excellent in long-lasting makeup, and the water type is excellent in removability in hot water. For both oil-based types and water-based types, techniques for further improving the quality while taking advantage of the respective advantages have been developed. For example, a technique for obtaining a makeup cosmetic characterized by containing a nonaqueous polymer dispersion in which a polymer is dispersed in a volatile silicone can provide a makeup-sustaining effect that does not cause makeup due to sweat, tears, sebum, or the like (see patent document 1). There is also a technique of using a makeup cosmetic containing a core-shell polymer emulsion, a hydratable oil agent, and a microcrystalline wax, wherein the mass ratio of the hydratable oil agent to the microcrystalline wax is 1 to 1. Further, an eye cosmetic composition has been developed which contains a silicone film agent in an amount of 10.01 to 30 mass% and a volatile oil in an amount of 25 to 70 mass% based on the total amount of the eye cosmetic composition, and has excellent makeup retention properties with the volatile silicone oil in an amount of 25 mass% or more based on the total amount of the volatile oil and has a hardness of 30 or more and 100 or less (see patent document 3).

The upper limit is preferably 30% or less, more preferably 25% or less, and still more preferably 20% or less.

The eyeliner cosmetic of the present invention can be prepared by a generally known method.

The eyeliner cosmetic of the present invention is not particularly limited, and may take the form of powder, solid, liquid, gel, etc., and is preferably liquid or gel from the viewpoint of non-halation property when a pen-type application is used or when a pen-type application is used. The eyeliner cosmetic of the present invention may be of an oil type or an aqueous type, and among them, an oil type is preferable. The oily type includes nonaqueous type and W/O type. In the present specification, the nonaqueous type means a type in which the content of water is 5% or less, preferably 3% or less, and more preferably 1% or less.
