Description

Cosmetics for Forming Double Eyelids The present invention relates to a cosmetic composition for forming double eyelids comprising a film-forming agent and a solvent. More specifically, the present invention relates to a cosmetic composition for forming double eyelids that has excellent double eyelid forming power and film retention, and has a good user experience without stickiness or stiffness. Double eyelids are considered an element of beauty, and cosmetic products for forming double eyelids are used as a means to create them more simply compared to procedures in cosmetic surgery. As cosmetic products for forming double eyelids, incision-type cosmetic products and adhesive-type cosmetic products for forming double eyelids are known. Incision-type cosmetic products (in a form that folds inward) are used to form a film that is harder than the skin on a part of the eyelid, and when the eye is opened, the eyelid folds inward at the boundary line between the film and the upper eyelid to form a double line. Also, adhesive-type cosmetic products for forming double eyelids are used to form a film on a crease (double line) prepared on the eyelid and fix the crease to form a double line. Conventionally, cosmetics for forming double eyelids containing natural rubber latex were used. However, natural rubber latex had the problem of causing mild allergic symptoms or severe anaphylactic shock in individuals with latex allergies. Therefore, in recent years, a double eyelid forming cosmetic containing an acrylic polymer resin as a film-forming agent and an adhesive containing an acrylic polymer resin have been proposed instead of natural rubber latex (see Patent Document 1 and Patent Document 2). The cosmetic composition for forming double eyelids according to the present invention is, It includes a film-forming agent and a solvent, The film-forming agent comprises a polymer having a norbornane structure, and also, The content of the polymer having the nobornene structure is 1% to 30% by mass based on the total mass of the cosmetic composition for forming double eyelids. The following describes each component. <Film-forming agent> The cosmetic composition for forming double eyelids according to the present invention comprises a polymer having a nobornene structure as a film-forming agent. A double eyelid can be formed, for example, by forming a film between the desired double line when the eyes are closed and the boundary where the eyelashes begin to grow, and by the eyelid folding in at the boundary between the film and the upper eyelid when the eyes are opened. Since polymers having a novonane structure have high strength and excellent flexibility, a film containing a polymer having a novonane structure is harder than skin and possesses the ability to form a double eyelid, allowing the eyelid to fold in at the boundary between the film and the upper eyelid when the eyes are opened. Furthermore, it possesses film durability, making it difficult for cracks or peeling from the skin to occur. Additionally, since polymers having a novonane structure are not sticky after drying, the film does not adhere to the eyelid due to blinking. In addition, a double eyelid can be formed by, for example, creating a crease (double line) in the left-right direction slightly above the edge of the upper eyelid and fixing the temporarily created crease with a cosmetic for forming double eyelids. Since polymers having a novelane structure have high adhesion to the skin and excellent flexibility, a film containing a polymer having a novelane structure has double eyelid forming power that can fix a temporarily created crease, and also has film durability that makes it difficult for the film to tear (rupture) or peel off from the skin to occur. In addition, polymers having a norbornene structure have excellent flexibility, so they can form a film with excellent usability without stiffness. Furthermore, since the film formed from acrylic polymer resin has low water resistance, if the film becomes wet—for example, during the summer or while exercising, or when washing the face, or entering a bathtub or pool—the adhesiveness decreases, causing it to peel off easily from the skin. Consequently, users who do not wish to reveal that they are using double eyelid cosmetics must take care to avoid sweating or getting wet. Moreover, if they do sweat or get wet, they may worry that the film has peeled off from the skin, leaving a single eyelid, or that they need to immediately reshape the double eyelid. On the other hand, the film formed from the polymer having a nobornene structure according to the present invention possesses water resistance, so it does not easily peel off from the skin even when wet. Therefore, users do not need to worry that the film will peel off from the skin and leave a single eyelid even when wet. Even during the summer, or on days when exercising or going into a pool, the cosmetic composition for forming double eyelids according
