Description

  The present invention relates to mascara. More specifically, the present invention is excellent in safety to the human body, and when applied continuously to the eyelashes, promotes the growth of the eyelashes themselves, making the eyelashes themselves longer or thicker (darker). Yes, it relates to mascara that can increase the number of eyelashes in some cases.

When mascara is applied to the eyelashes, the eyelashes appear dark and long, giving the eyes a patchy impression and expressing attractive beauty, so mascara has been widely used by many women in recent years as an eye makeup product. It is supposed to be.
With the widespread use of mascara, there has been a demand for mascara that can make the eyelashes darker and longer, and from this point, various studies on the types and composition of ingredients used in mascara have been conducted. .
As such conventional technology, mascara has been developed that increases the amount of colorant blended in mascara, blends fine fibers, and blends colorants and ingredients to improve adhesion of fine fibers to the eyelashes. Has been.
However, most of the conventional mascara can only make the eyelashes darken or look longer on the appearance only when the mascara is applied, and after dropping the mascara, the darkness and length of the eyelashes In other words, the state before applying the mascara was restored.

  The purpose of the present invention is not only to make the eyelashes darker and longer in appearance, but also to promote the growth of the eyelashes, thereby making the eyelashes longer or thicker. In some cases, the number of eyelashes can also be increased, and the eye makeup effect of mascara can be further improved, and long and dark eyelashes even after the mascara is dropped or not applied It is possible to provide a mascara that can be made and that is excellent in safety to the human body.

In order to achieve the above object, the present inventor has intensively studied. As a result, the hydrolyzed eggshell membrane has an effect of promoting the growth of eyelashes. Therefore, when the hydrolyzed eggshell membrane is blended with mascara and the mascara containing the hydrolyzed eggshell membrane is continuously applied to the eyelashes, the eyelashes appear apparently. In addition to the effect of making the eyelashes darker and longer, the growth of the eyelashes itself is promoted, making the eyelashes longer and thicker, and in some cases the number of eyelashes increases, and the eye makeup effect is even better. I found out that
Moreover, when mascara containing hydrolyzed eggshell membranes is continuously applied, as described above, the eyelashes themselves become longer or thicker, so when the mascara is dropped or when mascara is not applied In addition, the present invention has been completed by finding that the eyes look patchy and give an attractive impression.

That is, the present invention
(1) A mascara characterized by containing a hydrolyzed eggshell membrane.
And this invention,
(2) The mascara of said (1) which contains a hydrolysis eggshell membrane in the ratio of 0.05-1.5 mass% with respect to the total mass of a mascara is included as a preferable aspect.

The mascara of the present invention has an eye makeup effect that makes the eyelashes look long and dark on the appearance, gives a patchy impression to the eyes and expresses attractive beauty, and is continuously applied to the eyelashes. By promoting the growth of the eyelashes themselves, the eyelashes themselves can be lengthened or thickened. In some cases, the eyelashes further increase the number of eyelashes.
Therefore, when the mascara of the present invention is continuously applied to the eyelashes, the eye makeup effect by the mascara and the patchy effect by the eyelashes that are longer or thicker are combined to make the eye more attractive. Can be.
Furthermore, when the mascara of the present invention is continuously used, the eyelashes themselves become long and thick, so that the eye area is attractive even when the mascara is not applied or after the mascara is dropped. Can do.
Moreover, since the mascara of the present invention is a blend of a hydrolyzed eggshell membrane derived from a natural egg, it is excellent in safety.

The present invention is described in detail below.
The eggshell membrane is a membrane inside the eggshell of a bird's egg such as a chicken egg. The eggshell membrane is composed of two pieces inside and outside, the outer eggshell membrane is in close contact with the inner surface of the eggshell, and the inner eggshell membrane wraps the egg white.
The hydrolyzed eggshell membrane used in the mascara of the present invention is obtained by using such an eggshell membrane (outer eggshell membrane and / or inner eggshell membrane) inside a bird's egg using a proteolytic enzyme, acid, alkali or the like. It has been hydrolyzed, and its solubility or emulsification in a liquid such as water is improved by the hydrolysis treatment. In the present invention, any hydrolysis eggshell membrane that is soluble in water or easily dispersible in water can be suitably used as the hydrolysis eggshell membrane. EM protein "(trade name).

  The mascara of the present invention is a liquid medium mainly composed of water in terms of ease of application to eyelashes, prevention of dripping after application, ease of drying after application to eyelashes, safety to the human body, etc. The hydrolyzed eggshell membrane is dissolved or emulsified in the form of an aqueous emulsion in which various components necessary for the formation of mascara, such as colorants, adhesives, and other components, are dissolved or dispersed. It is preferable.

  The content of the hydrolyzed eggshell membrane in the mascara of the present invention is preferably 0.05 to 1.5% by mass and preferably 0.1 to 1.0% by mass with respect to the total mass of the mascara. More preferably, it is 0.3 to 0.7 mass%. If the content of the hydrolyzed eggshell membrane is less than 0.05% by mass, the effect of promoting the growth of eyelashes becomes small, and it becomes difficult to make the eyelashes longer or thicker. On the other hand, when the content of the hydrolyzed eggshell membrane exceeds 1.5% by mass, the cost is increased, and the tackiness is increased, which tends to cause a poor feeling of use.

The mascara of the present invention contains a mascara component conventionally used in mascara together with a hydrolyzed eggshell membrane.
Examples of such mascara-forming components include colorants, fiber powders for making eyelashes long, ingredients for giving eyelashes, waist, gloss, volume, etc., moisturizers, flame retardants, preservatives, pH adjustments Adhesives, emulsifiers, colorants, adhesives for attaching fiber powder and other ingredients to the eyelashes, ingredients for dispersing or dissolving the above ingredients in water, nutritional ingredients for nourishing the eyelashes and eyes, etc. 1 type or 2 types or more of the above-mentioned components can be used.

  As the colorant, any of those conventionally used in mascara can be used, for example, pigments such as black iron oxide, red iron oxide (Bengara), ultramarine blue, dyes, coloring aids such as diisostearyl malate, etc. Can be mentioned. The color of the mascara can be changed to, for example, black, dark brown, light brown, dark blue, light blue, and other color tones by adjusting the type, blending ratio, composition, and the like of the pigment and dye. The content of the pigment or dye can be the same as that in the conventional mascara, and is generally about 5 to 15% by mass of the pigment or dye with respect to the total mass of the mascara. Good. Further, the content of the coloring auxiliary such as diisostearyl malate is preferably about the same as the content of the pigment or dye from the viewpoint that the pigment or dye can be uniformly dispersed in the mascara.

  Further, as described above, the mascara of the present invention preferably contains fiber powder for making eyelashes long, and examples of the fiber powder include synthetic fiber powder such as nylon powder. When the fiber powder is contained, it is preferably about 1 to 10% by mass, particularly about 3 to 7% by mass based on the total mass of the mascara. In addition, as ingredients for giving eyelashes, waist, gloss, volume, etc., and attaching colorants and fiber powders to the eyelashes, for example, beeswax, microcrystalline wax, carnauba wax, acrylic copolymers, etc. These contents can be comparable to those of conventional mascaras. Examples of the humectant include polyvinyl pyrrolidone, 1,3-butylene glycol, hydroxyethyl cellulose, and propylene glycol. Examples of the preservative include alkyl paraoxybenzoates such as methyl paraoxybenzoate, methyl paraoxybenzoate, and propylene paraoxybenzoate. Examples of the emulsifier include polyoxyethylene sorbitan monostearate, and examples of nutritional ingredients for providing nutrition to the eyelashes and eyes include vitamins such as vitamin E.

  Furthermore, the mascara of the present invention includes, in addition to the above-described components, polyhydric alcohols such as glycerin and propylene glycol, fatty acids such as stearic acid, oleic acid, and palmitic acid, soybean oil, olive oil, castor as necessary. It can contain the same vegetable oils such as oil and squalane, triethanolamine, benzyl alcohol and the like.

  The components that can be contained in the mascara of the present invention are not limited to those described above, are components that are permitted for use in cosmetics and are conventionally used in mascara, and do not impair the effects of the present invention. As long as it is a thing, you may contain any component.

The pH of the mascara of the present invention is usually preferably in the range of 5 to 8.5, preferably 6.5 to 8 in terms of safety to the human body, prevention of corruption, affinity with eyelashes, and the like. Is preferred.
The mascara of the present invention can be used by filling bottles or other mascara containers and applying them to the eyelashes using an applicator.

  The reason why the mascara of the present invention containing a hydrolyzed eggshell membrane has the effect of promoting eyelash growth and making the eyelashes longer or thicker is not clear, but hydrolyzed eggshell membranes were generated in vivo Applying mascara containing hydrolyzed eggshell membranes to the eyelashes to reduce or eliminate harmful active oxygen, blood supply to the eye cells where the eyelashes grow smoothly This is presumably due to the promotion of eyelash growth.

  The method for producing the mascara of the present invention is not particularly limited, and a liquid (preferably emulsified) mascara in which the above-mentioned various components are uniformly dispersed and dissolved in a medium mainly composed of water without causing alteration or the like. Any method that can be manufactured may be used.
