Description

Cosmetic composition for increasing the density of eyebrows or eyelashes and promoting length growth

The present invention relates to a cosmetic composition, and more particularly, to a cosmetic composition for promoting density or length growth of eyebrows or eyelashes, which promotes growth of density and length by supplying nutrition to eyebrows or eyelashes.

In the era of self-PR, interest in beauty, regardless of gender, is increasing. A lot of attention is paid to the fact that the eyes occupy a large proportion in judging the beauty and can effectively change the impression. As interest in beauty increases, the desire for the functions of cosmetics is increasing. Accordingly, cosmetics with various functions are continuously appearing. In particular, the demand for cosmetics and beauty accessories for eyebrows or eyelashes is increasing.

In particular, in the case of eyelashes, various methods are used, such as a method of applying artificial eyelashes to an adhesive and attaching them on the eyelashes, and a method of applying mascara after curling the eyebrows using a curler. However, this method not only inhibits the growth of eyelashes, but also has a large degree of damage caused by the components of the adhesive and physical stimulation by the curler, which causes the problem of eyelashes being pulled out or thinning, and eventually hair loss. can occur

Accordingly, in the prior art literature, since the eyebrows or eyelashes exhibit different growth phases, resting phases, and growth rates from those of other parts of the hair, such as hair, when applying a composition or agent that has been conventionally used for hair promotion for growth of eyebrows or eyelashes , because it does not exhibit the desired degree of eyebrow or eyelash growth effect, by containing as an active ingredient one or more mixtures selected from the group consisting of sauerkraut extract, iris extract, ginseng extract, ginkgo leaf extract, red ginseng extract and arginine/lysine polypeptide. Disclosed is a composition for promoting eyebrow or eyelash growth that exhibits an excellent eyebrow or eyelash growth effect without causing eye irritation.

However, the prior art literature contains a limitation of recognizing only the increase in the length of the eyelashes. That is, in the prior art literature, there is no recognition of an improvement in the density of eyelashes. This is because, when only length growth is induced in a state in which the density of eyelashes is reduced, the overall density is reduced despite the length growth, thereby adversely affecting the cosmetic effect.

Furthermore, eyelashes have growth cycles of growth phase, catagen, and resting phase, and eyelashes fall out at the end of the catagen phase. This makes it difficult to achieve maximum effect.

Therefore, in order to solve this problem, it is required to develop a composition that causes a significant increase in density in addition to promoting growth by supplying nutrition to eyebrows or eyelashes, but related research is still insufficient.

Registered Patent No. 10-1829377, Title of Invention: An herbal extract effective against acne bacteria and a composition for promoting the growth of eyebrows or eyelashes containing the same {Composition for promoting the growth of eyebrow or eyelash}

The present invention is to solve the problems of the prior art, and an object of the present invention is to provide a cosmetic composition that promotes the increase in density or length growth of eyebrows or eyelashes.

In addition, it is an object of the present invention to provide a cosmetic composition that promotes the increase in density or length growth of eyebrows or eyelashes that minimize skin irritation by increasing affinity for hair.

The cosmetic composition for increasing the density of eyebrows or eyelashes and promoting length growth according to one aspect of the present invention contains myristoyl peptide-4, plankton extract, sauerkraut extract, and green tea extract.

In this case, the content of the myristoyl peptide-4, the plankton extract, the sauerkraut extract, and the green tea extract is 2.0 to 15.0% by weight, 0.01 to 0.2% by weight, 2.0 to 5.0% by weight, respectively, based on the total weight of the cosmetic composition, and It is preferable in terms of density increase and length increase that it is 2.0 to 5.0% by weight.

However, it is preferable that the content of the Sauerkraut extract is greater than the content of the green tea extract.

First, the cosmetic composition for increasing the density of eyebrows or eyelashes and promoting length growth according to the present invention is characterized in that it contains myristoyl peptide-4, a plankton extract, a succulent extract, and a green tea extract.

Myristoylpentapeptide-4 serves to prevent hair loss and promote hair growth by supplying nutrition to eyebrows, hairline, and eyelashes. Keratin is an important ingredient in hair, and myristoylpentapeptide-4, a small molecule, is easily absorbed and produces a lot of keratin to promote the growth of eyelash length, stimulate the keratin gene to produce more dead skin cells, and promote eyelash growth. It makes your eyelashes grow.

It has been known to darken gray hair when taken from ancient times, and has a tonic effect, an energy enhancing effect, and an effect to improve blood circulation in the brain. Anthraquinoids, chrysopamol, and emodin are known as major components of Hasuo. Hawthorn extract plays a role in increasing the proliferation of DPC cells to increase the length of the hair.

Unlike black tea or oolong tea, green tea does not undergo fermentation of tea leaves, and is obtained by inactivating oxidation-related enzymes and stably maintaining polyphenol components by steaming fresh, young tea leaves. 30-40% of polyphenols found in green tea are known as flavonols and catechins, and the main components of green tea catechins are epicatechin, epicatechin-3-gallate, and epigallocatechin ( epigallocatechin) and epigallocatechin-3-gallate (EGCG), and it is known that the content of epigallocatechin-3-gallate component is the highest among them. The polyphenol component of green tea is known to have various efficacy effects such as antioxidant, anticancer, anti-inflammatory, and antibacterial. Furthermore, it is widely known that green tea extract helps hair growth.

Plakton extract is a natural eyelash enhancer that reduces apoptotic cells in eyelashes and proliferates proliferation cells to make eyelashes fuller and grow into thick, healthy eyelashes.

At this time, myristoyl peptide-4 serves to induce the length growth of eyebrows, etc., and does not cause a significant change in terms of volume growth (density increase).

However, in order for the volume to grow, the growth of the length must also be premised, so the content of myristoyl peptide-4 is preferably from 2.0 to 15.0% by weight based on the total weight of the cosmetic composition. This is because, when the content of myristoyl peptide-4 is less than 2.0% by weight, substantially no length growth promoting effect occurs, and when it exceeds 15.0% by weight, the expression effect of volume growth, which will be described later, is reduced. That is, even when the content of myristoyl peptide-4 reaches 15.0% by weight, it can help the length growth, but when using the appropriate amounts of sewage slough extract, green tea extract, and plankton extract to be described later, myristoyl peptide- If the content of 4 exceeds 5% by weight, it is analyzed that density growth is rather hindered.

In addition, the present invention further contains an optimal amount of sauerkraut extract, green tea extract, and plankton extract for volume growth accompanied by an increase in density.

In this case, it is preferable that the extract of Sauerkraut contains 2 to 5% by weight relative to the total weight of the cosmetic composition, and it is preferable that the green tea extract also contains 2 to 5% by weight.

At this time, when the content of the green tea extract is less than 2% by weight, substantial density growth does not occur even when an appropriate amount of the sewage extract is added, and when the content of the green tea extract exceeds 5% by weight, the density growth becomes rather insignificant. Therefore, the optimum content of green tea extract plays a very important role in volume growth (density growth).

In addition, on the premise of the optimal content of green tea extract, if the content of the extract is less than 2% by weight, it does not cause an increase in density, and when the content of the extract is more than 5% by weight, the length growth is rather insignificant, so it is not preferable. not.

However, in this case, it is preferable that the content of the H. sauerkraut extract is greater than the content of the green tea extract. This is because the synergistic effect of increasing the density is expressed when the content of the sauerkraut extract is greater than the content of the green tea extract.

On the other hand, it is preferable that the plankton extract contains 0.01 to 0.2% by weight based on the total weight of the cosmetic composition. When the plankton extract is contained in an amount of less than 0.01% by weight, the effect of increasing the density does not appear, and when it exceeds 0.2% by weight, eye irritation is induced and a peculiar odor of seaweed is generated.

On the other hand, the cosmetic composition according to the present invention may further include a thickener, a preservative, and a moisturizing agent.

In addition, the formulation of the cosmetic composition according to the present invention may be provided as a product formed of at least one of liquid to viscous liquid, gel, emulsion, cream, and patch type.

Hereinafter, an experimental example of the present invention will be described.
