Description

Cosmetic for forming double eyelid Technical Field The present invention relates to a cosmetic for forming double eyelid containing a film forming agent and a solvent. More specifically, the present invention relates to a cosmetic for forming double-eyelid which is excellent in double-eyelid forming ability and film persistence and has no sticky feeling or stiff feeling and good feeling in use. Background The double eyelid is an element of beauty, and as a means for easily forming the double eyelid compared with an operation in beauty surgery or the like, a cosmetic for forming the double eyelid is used. As cosmetics for forming double-fold type double-fold eyelid, there are known cosmetics for forming double-fold type double-fold eyelid and cosmetics for forming double-fold-type double-fold eyelid. The inward folding type double eyelid cosmetic is used for forming a hard coating film on a part of an eyelid, and forming a double eyelid line by inward folding the eyelid at the boundary of the coating film and an upper eyelid when the eyes are opened. The paste type double eyelid-forming cosmetic is used to form a coating film on wrinkles (double eyelid lines) provided on the eyelid, and fix the wrinkles to form double. Conventionally, a cosmetic for forming double eyelid containing natural rubber latex has been used. However, natural rubber latex has problems of causing mild allergic symptoms and severe anaphylactic shock for latex allergic constitution people. Accordingly, in recent years, there has been proposed a double eyelid formation tool using a double eyelid formation cosmetic containing an acrylic polymer resin as a film forming agent and an adhesive liquid containing an acrylic polymer resin instead of a natural rubber latex (see patent document 1 and patent document 2). Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2014-24762 Patent document 2 Japanese patent laid-open No. 2006-255333 Disclosure of Invention Technical problem to be solved by the invention The cosmetics or adhesive solutions for forming double-eyelid containing the acrylic polymer resins used in patent document 1 and patent document 2 have strong adhesive force and excellent double-eyelid forming ability due to fixation of wrinkles. In addition, the acrylic polymer resin can form a film harder than the skin, and thus also has double eyelid forming ability by inward folding. However, since the acrylic polymer resin is hard, there are problems that the film gives a stiff feel, and the film is not able to follow the movement of the eyelid such as blinking, and the film sustainability such as film breakage and peeling and the feel of use are poor. In addition, the acrylic polymer resin has low water resistance, and has problems such as sticky feel of the film due to moisture or sweat, and poor film persistence and use feel such as peeling of the film from the skin. Further, since a film formed from a cosmetic material for forming double-fold eyelid or an adhesive liquid containing an acrylic polymer resin has poor film persistence, it is not usable as a cosmetic material for forming double-fold eyelid. Accordingly, an object of the present invention is to provide a cosmetic for forming double-fold eyelid which is excellent in double-fold eyelid formation ability and film persistence, does not cause a sticky feeling or a stiff feeling, is excellent in use feeling, has an excellent double-fold eyelid formation effect, and can be used in either of an inward-fold type and an adhesive type. Means for solving the technical problems As a result of intensive studies to solve the above problems, the present inventors have found that a cosmetic for forming double-fold eyelid, which can exert an excellent double-fold eyelid forming effect, can be obtained by using a polymer having a norbornane structure as a film forming agent, and have completed the present invention. That is, the present invention relates to a cosmetic for forming a double eyelid, which comprises a film-forming agent and a solvent, wherein the film-forming agent comprises a polymer having a norbornane structure, and the content of the polymer having a norbornane structure is 1 to 30 mass% based on the total mass of the cosmetic for forming a double eyelid. The polymer having a norbornane structure is preferably a silicone-modified polymer having a norbornane structure. The content of the polymer having a norbornane structure is preferably 7.5 to 18 mass% based on the total mass of the cosmetic for forming double eyelid. The solvent is preferably at least one solvent selected from the group consisting of volatile hydrocarbon oils, volatile silicone oils, and liquid oils. Effects of the invention The cosmetic for forming double eyelid of the present invention has excellent double eyelid forming ability as an inward fold, that is, a coating film formed by the cosmetic for forming double eyelid of the present invention has hardne
