2. Description of the Related Art Eyelash cosmetics have a cosmetic effect such as curling the eyelashes upward and making the eyelashes thick and long so that the eye area becomes clear. Conventionally, these eyelash cosmetics are composed mainly of solid oil components, for example, waxes and waxes, and powders, film-forming agents, water-soluble polymers, etc., and various usability required as cosmetics, In order to provide usability and functionality, various formulations and mixing of raw materials have been studied. For example, in terms of functionality, emulsifying type eyelash cosmetics are mentioned, and these can be applied to the eyelashes by increasing the amounts of waxes and waxes having a relatively low melting point and various film-forming agents. This enhances the makeup effect, such as making the eyelashes stand out thicker, and fixing the eyelashes in a curled up state to make the eyes more prominent. Furthermore, a cosmetic effect (long lash effect) such as making the eyelashes longer can be produced by blending fibers such as nylon with these systems. In terms of usability and usability, there are transparent eyelash cosmetics mainly composed of water-soluble polymers,
It has a smooth feeling of use and a natural finished feeling.

[0003]

However, in a transparent type eyelash cosmetic which can provide a natural finished feeling, since a water-soluble polymer is mainly used, it is necessary to mix waxes and waxes which are oily components. However, sufficient cosmetic effects such as thickening the eyelashes were not obtained. On the other hand, by increasing the amount of the film-forming agent and forming a hard film on the eyelashes, a cosmetic effect such as curling the eyelashes and making the eyes stand out can be produced, but after makeup,
There is a disadvantage that the finished film becomes unnatural due to the whitening of the decorative film over time and the loss of transparency.

[0004]
