Description

[0001] The present invention relates to a cosmetic composition for promoting eyelash growth,

The present invention relates to a cosmetic composition for promoting eyelash growth, and more particularly, to a cosmetic composition for enhancing eyelash growth, which comprises a keratin, a silk amino acid, a collagen, a biotin and a complex component of inositol The present invention relates to a cosmetic composition for promoting eyelash formation and growth.

With the increasing interest in cosmetics in modern society, the desire for cosmetics to function is increasing, and high-function products are constantly emerging accordingly.

In general, cosmetics are much more popular among men than men, and a wide variety of cosmetics have been developed and used depending on the area where cosmetics are made. Especially, since the eye occupies a great part in judging the beauty of women, and the eye make-up is the easiest and most effective part of the face change, women are paying much attention to make-up eyes. As eyebrows and eyelashes become thicker and richer in the eye make-up, the eyes are finished and the face is enhanced.

Especially, eyelashes are one of the most emphasized facial parts of femininity. You can see beauty effects that make your eyelashes rich and long and your eyes bigger and clearer.

These eyelashes exhibit significant differences from the hair of other parts such as scalp hair in terms of periods of growth and dormancy. In the case of hair, the growing period lasts for about 3 to 4 years, the pause period lasts for 3 to 4 months, the proportion of the growing period is 85 to 93% of the whole cycle, and the ratio of the pause period is 7 to 15% And the growth rate is about 0.4 mm / day. On the other hand, in the case of eyelashes, the growth period is 6-10 weeks, the resting period is maintained for 4 ~ 9 months, the proportion of growth period is 10 ~ 20% of the whole cycle and the ratio of resting period is 80 ~ 90% And the growth speed of the eyelashes is about 80 ~ 280 ㎛ / day, which shows a considerable difference from the hair growth rate. In spite of this difference, conventionally, a hair growth agent (hair growth agent) used for hair has been used for promoting the growth of eyelashes. However, there is a problem that the same effect as that of hair is not generated in the eyelashes due to the difference between the hair and eyelashes. Further, since the eyelashes are located near the weakest eyes of the human body, there has been a problem that when using the hair growth agent (hair growth agent) used in conventional hair, there is a serious risk to eyes.

Meanwhile, cosmetics for eyelashes include eye shadow, eye line, eye pencil, and mascara. Among them, Mascara is an eyelash cosmetic that is essential for most women's make-up. Its purpose is to make the eyelash look darker and lengthened by making the eyelash black and straight, making it look more beautiful.

However, even when the mascara is applied to the eyelashes, the eyelashes themselves are not long. Therefore, when the eyelashes are used by women having a short or thin hair, the effect is not large. To solve these problems, artificial eyelashes It is. However, since artificial eyelashes are not easy to attach artificial eyelashes directly to the eyes, there is a disadvantage in that a specialist's hands are required. In addition, the user feels uncomfortable when the user is blinking the eyes even after putting them together. There are many problems.

In the field of cosmetics, research is underway to develop a lash balm or an eyelash raising agent that can not only make lashes look longer, but also can grow or promote the growth of lashes themselves. So that human stability is essential.

For example, in Korean Patent No. 10-1270965, a cosmetic composition for promoting eyebrows or eyelash growth is disclosed, which comprises a natural substance such as paprika, mung bean, gugija, mulberry leaf, pine needles, And Korean Patent No. 10-12073175 discloses a green tea extract which is a mixture selected from the group consisting of Ganoderma lucidum, Guerbet, Eucalyptus, Hansikcho, Windbreak, Rubus japonica, Korean Patent Laid-Open Publication No. 10-2005-0077310 discloses a cosmetic composition for enhancing eyebrows and eyelash growth comprising a crude herbal extract and an eyelash growth promoter containing a polygonum tinctorium extract belonging to Polygonaceae .

Therefore, the inventors of the present invention have been studying to develop a eyelash nutrient that has a remarkably excellent effect in accelerating eyelash growth and has secured the stability in the human body, and has been studying keratin, silk amino acid, collagen collagen, biotin, and inositol at a certain ratio has an excellent effect in accelerating the growth of eyelashes, as compared with the conventional products. Thus, the present invention has been completed.

Accordingly, a technical problem to be solved by the present invention is to provide a cosmetic composition for promoting eyelash growth, which promotes the growth of eyelashes without causing irritation to the eyes of the human body, and can nourish hair and hair roots and exhibit a substantial effect.

In order to solve the above-mentioned technical problems, the present invention provides a method for producing a protein having keratin, silk amino acid, collagen, biotin and inositol in a ratio of 4: 2: 2: 1: 2: 3: 3: 2: 2, as an active ingredient. The cosmetic composition for accelerating eyelash growth is characterized by comprising

In the cosmetic composition for promoting eyelash growth of the present invention, keratin, which is one of the components used as an effective ingredient, is a protein bound to 18 kinds of amino acids, and particularly contains a large amount of amino acid called cysteine. It contains nutrients similar to Moh's to help nourish and strengthen healthy and healthy lashes.

The silk amino acid, which is one of the components used as the active ingredient in the cosmetic composition for promoting eyelash growth of the present invention, is a natural product obtained from silkworm cocoons and contains a high quality protein and essential amino acid, and thus has an effect of imparting moisturizing effect to the hair.

Biotin, one of the components used as an active ingredient in the cosmetic composition for promoting eyelash growth of the present invention, acts as a coenzyme and has a metabolic-promoting action to help promote hair growth.

Collagen, which is one of the components used as an active ingredient in the cosmetic composition for promoting eyelash growth of the present invention, is a protein which is a main component of a binding component. In the present invention, marine collagen is particularly used, Stimulates the regeneration of the skin, improves immune function, activates metabolism, maintains moisturizing power, and strengthens and strengthens the hair.

Inositol, one of the components used as an active ingredient in the cosmetic composition for promoting eyelash growth of the present invention, has an efficacy to normalize nerve cells while relaxing nerve cells, and has an effect of uniformly delivering nutrients to hair follicles.
