The present invention relates to eyelash extension aids using nylon monofilaments.

Mascara is a cosmetic that makes the face look three-dimensional by further emphasizing the protruding eyelashes and maintains a 30% share of eye cosmetic products every year.

In particular, Korean women have thin eyelashes and droop downwards, and since the eyelashes are shorter because they have more single eyes than double eyes, it is important to make long and voluminous trimming with mascara. .

Accordingly, the effects of mascara are mainly divided into long-lash effect, volume-up effect and curl-up effect (Kwak. Et al., 2002: 155). The long-lash effect is that after applying mascara, the length of the eyelashes is actually 1 to 2 mm long. In addition, the curl-up effect is an effect of raising the lashes, all three effects have the effect of making the eyes more vivid and make the face three-dimensional.

On the other hand, mascara is classified into a cream state, a cake state, and a liquid state according to the form. The cake-like product is called the stearate type and is an early mascara. It is a mixed material of carbon black and coconut oil, a weak alkaline substance of palm oil, or a triethanolamine stearine acid salt, and a solid form of carbon black. When used, it is applied to the eyelashes in a slightly dissolved state by mixing water. Cake-like products have a problem of being easy to make up and lasting, but easily soluble in tears or rain because the soapy materials are easily dissolved in water.

Liquid mascara is a mascara using a volatile aqueous solution, and the aqueous solution is used in a container in which a brush is attached to a cap which locks like a screw. While there is an advantage that it dries faster than the cake type and is convenient to carry, there is still a problem of being easily erased in water because it is an aqueous solution.

Creamy mascara is used as a cream base with the solvent used in the liquid mascara and other solvents other than water, and the dye is replaced, or a suitable dye is used for oils and fats to reduce the surface tension. Use a solution with a constant viscosity prepared by containing a wetting agent. The mascara does not dissolve in water and has the advantage of being evenly applied to the eyelashes without flowing or lumps. Currently, most mascaras are mostly creamy.

On the other hand, recently, the function of mascara is emphasized, and the mascara is classified according to the function of mascara.

Volume mascara is a mascara that emphasizes the effect of the volume-up among the effects of the mascara, by using a thicker mascara brush hair and increasing the density of the hair to make the eyelashes thick and thin. However, there may be a problem that a lot of smearing on the eyelashes at once spread or entanglement between the eyelashes.

 Long-lash mascara is a mascara that emphasizes the long-lash effect to make the eyebrows look longer.It is a small fiber added when applying mascara to the eyelashes by using a solution that is easy to form a film or by adding a small rayon in the cream-type mascara solution. They are attached to the eyelashes and have an effect of extending the eyelashes. However, the mascara solution to which the small fiber is added has a problem that the fibers in the solution are entangled and have an increased viscosity more easily than the solution to which the fiber is added, and thus cannot be used even before the solution contained in the container is exhausted [Wilkinson & Moore, 1982, 341-344.

In addition, there is a water proof mascara that is not erased even by contact with water, a base mascara which is fixed with a black silicone mascara after fixing the eyelashes with a white silicone rubber solution.

Of these, the most interesting mascara is the long-lash mascara, which is most effective in making faces look three-dimensional. To solve the problem of the long-lash mascara, Montiel et al. Devised a method of separating and extending small rayon fibers (US Pat. No. 4,135,527). The mascara consists of a container containing an aqueous solution containing a hydrolyzed protein and a container containing only 2 to 5 mm of rayon filament. First, an aqueous solution containing the hydrolyzed protein is applied to the eyelashes. After applying the rayon fibers to the moistened eyelashes, and then aligning the rayon fibers in the same direction as the eyelashes with a brush, the aqueous solution is buried again, the fibers are connected in the longitudinal direction to extend the eyelashes. Since the above method does not add the rayon fibers into the solution, the problem of increasing the viscosity of the mascara solution is solved, and there is an advantage that all the capacities contained in the container can be used. However, rayon has a specific gravity of about 1.23, and after using it on the eyelashes, it can give a heavy feeling and has a strong hydrophilicity, so it is easy to fall off the eyelashes.

In the present invention, the specific gravity is lighter than commercially available cream-type mascara and rayon, and the monofilament having a triangular cross section is used to increase the contact area with the eyelashes. It was confirmed that it was possible to complete the mascara of the present invention.

It is an object of the present invention to provide eyelash extension aids to extend the length of eyelashes.

In order to achieve the above object, the present invention provides an eyelash extension aid using nylon monofilament.

Hereinafter, the present invention will be described in detail.

In the eyelash extension adjuvant according to the present invention, the nylon monofilament may be a monofilament made of nylon 6 as a raw material. Since the nylon monofilament has a process water content of 4 to 5% and a specific gravity of 1.1, it is lighter than rayon having a process water content of about 11% and a specific gravity of 1.23, and has excellent water resistance to reduce heavy feeling when extended to the eyelashes, and the nylon The monofilament can be prevented from falling off the eyelashes.

In addition, the eyelash extender according to the present invention is preferably used to draw a nylon yarn having a thickness of 13 to 18 ㎛. In this case, when the eyelash extender is 18 μm or more, the eyelash extender may easily come off from the eyelashes, and when the eyelash extender is 13 μm or less, there is a problem that the extension rate of the eyelashes is lowered.

Furthermore, it is preferable that the nylon yarn used for the eyelash extender according to the present invention has a triangular cross section.

Triangular cross section nylon yarns are very effective in extending the eyelashes because they can maximize the contact area with the eyebrows.

However, this does not preclude the use of nylon yarns having a round or square cross section.

The eyelash extension aid according to the invention preferably uses a nylon filament cut to have a length of 0.8-2 mm. If the length of the nylon filament is less than 0.8 mm, the effect of elongating the eyebrows is less, if there is more than 2 mm there is a problem that the nylon filament can easily fall off the eyelashes.

Eyelash extenders according to the present invention can be prepared by the following method. First, a nylon 6 yarn with a triangular cross section is swelled in contact with water for a few seconds to minimize dust generation during fabrication.

The swollen nylon yarn is cut with a cutting device adjusted to cut to the desired length.

Since the cut nylon filament contains moisture, the agglomeration occurs, so that the cut nylon filament is dried by using a hot air dryer. The dried nylon filament may be packaged in a container to prepare the eyelash extender of the present invention.

Eyelash extender according to the present invention can be used in the following way.

First, apply a cream mascara to the eyelashes, then apply the eyelash extender according to the present invention, and comb out from the inside of the eyelashes using the brush of the cream mascara, the eyelash extender is aligned in the same direction as the eyelashes and At the same time, the eyelash extender can be entangled.

Hereinafter, the present invention will be described in detail through examples. However, the following examples are only for exemplifying the present invention, and the contents of the present invention are not limited to the following examples.

Production Example: Preparation of Eyelash Extender

Nylon yarns (Rhodiapolyamide, France) of triangular cross section were drawn, and then passed through a batch of water to swell the yarns. The swollen yarn was cut to a length of 0.8-2 mm using a guillotine type cutting machine (Berger, Germany). The cut nylon filament was hot air dried in a drier at 130 to 150 ° C. for 10 to 20 minutes to prepare a final eyelash extender.

1 and 2 are photographs of the eyelash extender according to the present invention observed with an optical microscope. As shown in Figure 1, the eyelash extender according to the present invention has a length of 0.9 to 15 mm and a thickness of about 16 μm. 2, the eyelash extender has a triangular cross section with a clear angle.

Example 1 Measurement of Eyelash Extension Rate Using Eyelash Extender

In the embodiment according to the present invention, after applying the cream form mascara to the natural eyelashes, applying the eyelash extender according to the present invention, using a brush of the cream form mascara combing from the inside of the eyelashes to the outside to extend the eyelashes . This is compared with natural eyelashes without using both mascara and eyelash extender (Comparative Example 1) and eyelashes coated with cream mascara (Real Long Lash Mascara, AMOREPACIFIC Co., Ltd.) on natural eyelashes (Comparative Example 2). The ratio is measured and the results are shown in Table 1 and FIG.

As shown in FIG. 3 and Table 1, the eyelashes of Comparative Example 1 without any treatment were 5 to 6 mm (average 5.5 mm), and Comparative Example 2 to which only cream mascara was applied was 6 to 7 mm (average 6.5 mm). Example 1 using the eyelash extender according to the present invention has a length of 12 to 13 mm (average 12.5 mm). Thus, compared with Comparative Example 1, the average extension rate of Comparative Example 2 is 20%, but the effect of the eyebrows are long even when using a general mascara in the form of a cream, but when using the eyelash extender according to the present invention is extended by 127% By showing the rate, it was confirmed that there is an extension effect of about 6 times than the cream mascara.

Eyelash Length (mm) Average Extension Rate (%) Example 1 12-13 (12.5) 127 Comparative Example 1 5-6 (5.5) 0 Comparative Example 2 6-7 (6.5) 20

The present invention has a smaller specific gravity than eyelash extenders using conventional rayon through eyelash extenders using nylon monofilament, and makes the face more three-dimensional by making long and voluminous eyelashes without falling off easily from the eyelashes. Aesthetic effect can be enhanced.
