Description

  The present invention relates to a cosmetic for eyelash correction and an eyeliner that can correct eyelashes upward.

  When the eyelashes are corrected upward, the eyes look patchy and the face looks cute. To correct the eyelash upward, pinch the eyelash strongly with a eyelash curler (eyelash corrector), force the eyelash upward to correct the eyelash, and apply an upward permanent to the eyelash. A method of correcting eyelash upward is known.

  The method of correcting the eyelash upward by strongly pinching the eyelash with a bura has the advantage that the eyelash can be easily corrected upward by itself. However, the method of correcting the eyelashes upward with a bura has the disadvantage that the eyelashes are strongly pinched with the bura, so that the eyelashes are broken in the middle (so-called cuckoo eyelashes), and the corrected eyelashes cannot be seen clearly. . In addition, the method of correcting the eyelash upward with the bura has a drawback in that the eyelash easily returns to the original downward shape with time because the eyelash is forcibly attached to the eyelash.

  On the other hand, the method of correcting the eyelash upward by applying an upward permanent to the eyelash has an advantage that the eyelash can be maintained for a long time in the upward state. However, the method of correcting the eyelash upward by applying an upward permanent to the eyelashes uses the perm solution near the eyeball, so it is necessary to ask a professional person for the eyelash perm, which is troublesome There is.

  Under the circumstances as described above, there has been a demand for a safe means by which the eyelashes can be easily corrected upward by themselves and the state can be maintained for a long time.

  Then, the inventor of the present application applied a double wrinkle-forming treatment agent according to another patent application (see Japanese Patent Application Laid-Open No. 2-188512) proposed by the applicant in a streak shape along the root of the eyelashes, and the formed film It was discovered that the shrinkage of the eyelashes caused the skin at the base of the eyelashes to be pulled upward and the base of the eyelashes to face upward, and that this phenomenon can be used as a means for correcting eyelashes.

  That is, the cosmetic for correcting eyelashes according to the present invention comprises a liquid in which fine particles of an organic polymer compound are dispersed in water, and the organic polymer compound has an affinity for the skin when the liquid dries. A film is formed, and the film shrinks as it is dried.

  Here, the specific physical property value of this film is preferably 100 to 150 as the hardness according to the JIS K 6301 method with an elongation of 300 to 500%. Examples of the organic polymer compound include a mixture of an organic polymer compound forming a rubber latex and an organic polymer compound forming a synthetic resin emulsion.

  The rubber latex may be natural rubber latex or synthetic rubber latex, but does not exceed the legal limit standard of harmful substances for human body and environment. For example, LA latex (total alkali content is 0.8). % Or less) can be used.

  The synthetic resin emulsion is added for the purpose of improving the drying property of the rubber latex and improving the water resistance and sweat resistance (saline resistance) as a physical property of the dried coating film and replenishing the hardness. . As such a synthetic resin emulsion, those having good compatibility with the rubber latex described above, having a minimum film-forming temperature of 20 ° C. or less, and having good water resistance and sweat resistance should be used. Can do.

  The type of the synthetic resin emulsion is not particularly limited. For example, a commercially available emulsion type acrylic resin, urethane resin, or chloride having an average molecular weight of 400,000 to 2,000,000 and a solid content of about 38 to 55 wt% is used. Vinyl resins such as vinyl, styrene resin, and vinyl acetate resin can be used.

  The ratio of the rubber latex in the liquid can be 40 to 62 wt%, and the ratio of the synthetic resin emulsion can be 55 to 33 wt%. However, there are individual differences in skin tension depending on the person, so from the viewpoint of obtaining an effect of reliably correcting eyelashes of people with strong skin tension, 45 to 57 wt% of rubber latex and 38 to 50 wt% of synthetic resin emulsion % Is preferable.

  This cosmetic for correcting eyelashes contains ammonia and alkanolamine, and the pH is preferably in the range of 8.0 to 10.0, and the alkanolamine is preferably in the range of 0.1 to 5 wt%. When the pH is in the range of 8.0 to 10.0 or the alkanolamine is contained in an amount of 0.1 to 5 wt%, there is an advantage that the eyelash correction cosmetic is difficult to coagulate even if stored for a long period of time.

  This cosmetic for correcting eyelashes contains a pigment having a concentration sufficient to form an eyeline, and may also be used as an eyeliner. As this pigment, a black pigment, brown pigment, red pigment, blue pigment or a mixture thereof can be used. As the black pigment, for example, carbon black subjected to hydrophilic treatment can be used. Carbon black has a concentration sufficient to form an eyeline at 1 wt% or less.

  In addition to the above-described components, this cosmetic for correcting eyelashes may contain antioxidants, pigments, antibacterial agents, fragrances, fillers, and other additives used for cosmetics. For example, 3 to 5% water, 1% or less polycarboxylic acid soda, 1% or less propylene glycol (PG), 1% or less aqueous ammonia, 1% or less ammonium glycyrrhizinate, 1% or less methylparapen, % Propylparapen, 1% quaternium-73, 1% PEG-40 hydrogenated castor oil, 1% laureth-21, 0.5% sodium dehydroacetate and the like. .

  Moreover, since the thickness of the cosmetic for correcting eyelash correction causes the user to feel uncomfortable, it is preferably 50 to 5 μm depending on the softness of the user's eyelids.

  In the present invention, after the eyelash correction cosmetic is applied in a streak shape to the base of the eyelash, as the eyelash correction cosmetic dries, the edge of the eyelid is lifted upward by the film being formed, and the eyelash hairline part is raised. As a result, the eyelashes face upward, the eyes look patchy, and the face looks cute.

  In addition, since the present invention is composed of a chemically stable substance such as rubber latex or synthetic resin emulsion, there is little danger to the skin and the eyeball, and it is very safe to use around the eyes. effective.

  The film formed by the cosmetic for correcting eyelashes is transparent, but may have a slight shine on the surface. In such a case, the surface of this film can be brought closer to a natural skin feel by lightly rubbing with a cotton swab. The present invention eliminates the need to worry about such unnaturalness because there is no need to bring the surface of the formed film close to the skin feeling when a black pigment is added and used as an eyeliner. is there.

  In addition, in the present invention, when a black pigment is used and the eyeliner is also used, the dark pigment forming the eyeline is firmly held in the coating, so even if the eyeline rubs at the edge of the eyelid There is an effect that the eyeline is not taken out and the eyeline is not blurred and spreads.

  Further, in the present invention, when a black pigment is added and used as an eyeliner, the eyelashes can be improved by applying the eyelash correction cosmetic (eyeliner) linearly at the base of the eyelashes, and the eyeliner. Is formed, so that the makeup time around the eyes is shortened and the makeup around the eyes becomes easy.

It is a front view of eyes. It is explanatory drawing which shows the cross section of the eyelash vicinity before correction. It is the A section enlarged view of FIG. It is explanatory drawing which shows the cross section of the eyelash vicinity after correction. It is the B section enlarged view of FIG.

  The purpose of providing a highly durable correction means that can easily correct eyelashes upward and maintain the state for a long time has been realized by a cosmetic composition for correcting eyelashes with a simple composition.

  Natural rubber latex, (styrene / alkyl acrylate) copolymer ammonium, water, carbon black, ammonia water, ethanolamine and benzoate were weighed in the proportions shown in the column of sample numbers 1 to 10 in Table 1, respectively. Each test liquid (eyelash correction cosmetics) was formed by gently mixing in a beaker.

  Here, a natural rubber latex having a total solid content of 62%, a total alkali content of 0.7%, a sludge content of 0.09%, a coagulation content of 0.07%, and a mechanical stability of 600 sec is used. did. In addition, (styrene / alkyl acrylate) copolymer ammonium having an average molecular weight of 1 million and a solid content of 45% was used.

  Next, each test solution was applied linearly to the base of the eyelash, and the change in the angle of the eyelash at 30 minutes and 90 minutes after drying was visually observed and evaluated. The evaluation results are as shown in Table 1. Here, the case where the eyelashes were completely corrected upward was marked as 、, the case where the eyelashes were corrected upwards to some extent, and the case where the eyelashes were not corrected upwards at all.

  From the results shown in Table 1, it can be seen that if the rubber latex ratio is in the range of 40 to 62 wt% and the synthetic resin emulsion ratio is in the range of 33 to 55 wt%, the eyelashes can be improved. And if the ratio of rubber latex is 45 to 57 wt% and the ratio of synthetic resin emulsion is in the range of 38 to 50 wt%, it can be seen that the effect of raising eyelashes is high.

  A synthetic resin emulsion other than (styrene / alkyl acrylate) copolymer ammonium is used as a synthetic resin emulsion, and a cosmetic for correcting eyelashes is prepared under the same conditions as in Sample No. 1 of Example 1, and linearly formed at the base of the eyelashes. The change of the eyelash angle at 30 minutes and 90 minutes after application and drying was visually observed and evaluated. The results were as shown in Table 2. Here, the case where the eyelashes were completely corrected upward was marked as 、, the case where the eyelashes were corrected upwards to some extent, and the case where the eyelashes were not corrected upwards at all.

  Synthetic resin emulsions other than (styrene / alkyl acrylate) copolymer ammonium include styrene resin emulsion (average molecular weight 1.2 million; solid content 55%), vinyl acetate resin emulsion (average molecular weight 800,000; solid content 40%), vinyl chloride resin Emulsion (average molecular weight 1.2 million; solid content 50%), acrylonitrile butadiene resin emulsion (average molecular weight 800,000; solid content 40%), styrene butadiene resin emulsion (average molecular weight 1.5 million; solid content 38%), styrene acrylic copolymer resin Emulsion (average molecular weight 1 million; solid content 46%), vinyl acetate acrylic copolymer resin emulsion (average molecular weight 2 million; solid content 54%), vinyl chloride acrylic copolymer resin emulsion (average molecular weight 400,000; solid content 45%) It was used.

  From the results shown in Table 2, it can be seen that even if a synthetic resin emulsion other than (styrene / alkyl acrylate) copolymer ammonium is used as the synthetic resin emulsion, it has an effect of improving eyelashes.

  Next, the movement of the skin and eyelashes when the cosmetic for correcting eyelashes is applied in a streaky manner to the base of the eyelashes will be described with reference to FIGS. 1 is a front view of the eye, FIG. 2 is an explanatory view showing a cross section near the eyelash before correction, FIG. 3 is an enlarged view of a portion A of FIG. 2, and FIG. 4 is an explanatory view showing a cross section near the eyelash after correction. FIG. 5 is an enlarged view of part B of FIG.

  First, as shown in FIG. 1, the eyelash-correcting cosmetic product 14 according to the present invention is applied in a streak pattern to the outside of the eyelash 12 at the edge of the eyelid 10 with a brush. If the eyelash correction cosmetic 14 is left for a while, the organic polymer compound contained therein is aggregated to form a film 14.

  If this film 14 is further left to stand, drying proceeds and further shrinks. Since this film 14 has a certain degree of tensile strength, has a good affinity with the skin, and is in close contact with the skin, the skin near the base of the eyelashes 12 is formed as shown in FIGS. 14 is pulled and is pulled forward or upward as indicated by an arrow C.

  Immediately after applying the eyelash correction cosmetic 14, the root skin of the eyelashes 12 faces forward or downward as shown in FIGS. 2 and 3, and the eyelashes 12 also face forward or downward. Thus, when the skin near the base of the eyelashes 12 is pulled forward or upward as indicated by an arrow C by being pulled by the contraction of the film 14, the eyelashes 12 move as shown in FIGS. To turn upward.

  Next, when removing the film made of cosmetics for correcting eyelashes, a remover widely used as a makeup remover is included in cotton, the film is moistened with this cotton for a while, and the film is gently rubbed with cotton. The film is wiped off by the remover and its adhesion to the skin is reduced, so it can be wiped off the skin with cotton.
