Description

Technical Field [0001] The present invention relates to a cosmetic composition for lip care containing natural ceramide and rose hip oil as an active ingredient,

The present invention relates to a lip cosmetic composition containing natural ceramide and rose hip oil as an active ingredient.

The lips are bordered at the edge of the mouth, developed only in mammals, and appear red because they have many capillaries. Lips are constantly contraction and swelling movements, one of the most moveable parts of the body, and because there is no pores in the lips, they do not secrete sweat or sebum, so natural moisturization is not formed.

Also, since the lips are always exposed to the outside, they are easily stimulated by environmental factors such as ultraviolet rays, pollutants in the air, and dry climate. The skin structure of the lips is unlike the general skin structure and there is no skin, and the horny layer is formed extremely thin, so that the amount of natural moisturizing factor and moisture is absolutely insufficient and the rate of moisture evaporation is extremely fast.

Due to this characteristic, the lips are severely damaged due to their weak ability to defend themselves against external stimuli. Accordingly, it can be understood that the lip cosmetic composition should have a more thorough moisturizing action unlike the other cosmetic compositions.

A cosmetic composition for a lip means a cosmetic composition that is used for the purpose of protecting the lips while at the same time showing a beautiful effect by giving a color effect to the lips.

As typical components of such a lip cosmetic composition, there is a solid component wax which first increases the hardness to maintain the appearance of the lip cosmetic composition. Commonly used waxes include candelilla lead, ceresin, carnauba wax, paraffin , Wood wax, beeswax, beeswax, microcrystalline wax, and the like are used. When the content of these solid waxes is high, the hardness of the lip cosmetic composition becomes high and hard, the feeling of use becomes heavy and the wettability becomes poor. However, it is easily disintegrated and the amount of burnt is increased, and it is not uniformly applied to the lips, and the blurring occurs along the lip line.

Second, liquid oily components such as jojoba oil, squalane, lanolin oill, lanolin derivatives, oils extracted from plants and animals, synthetic ester oils and silicone oils can be mentioned. Depending on the selection and content of these oily components, As well as other factors.

Thirdly, there are pigment components composed of organic and inorganic pigments. In case of organic pigments, they are generally highly soluble, and these dyes are hardly used in cosmetic composition for lips because of the possibility of sticking to lips. However, In addition, pigments that make such dyes into insoluble rake are also used. In addition, inorganic pigments such as iron oxide are used.

Fourthly, it may contain other ingredients such as an antioxidant, preservative, fragrance, and nutrients in addition to an effective ingredient, vitamins, high moisturizing or antioxidant ingredients for improving the lips state. In addition, ultraviolet rays to protect the lips from the purpose and to prevent roughening may be blended with ultraviolet rays and special nutrients.

So far, the following methods have been used to moisturize the lips through cosmetics. The first is to administer water or a hydrophilic component directly. Particularly, in order to mix water, there is a possibility of volatilization during the process. Particularly, when water is merely mixed for moisturizing effect, water is volatilized to promote drying of the lips or contraction of the contents .

Second, for the purpose of protecting and moisturizing lips, fatty acid and ester-based compositions including lanolin, lanolin derivatives, cholesterol derivatives, and alcohol groups are used. However, allergies have been reported in lanolin and lanolin derivatives and are currently being used in limited use. In addition, in the case of cholesterol derivatives, when the amount of the cholesterol derivative is 5% or more in consideration of the moisturizing effect, the feeling of use becomes sticky and heavy.

As with the skin, wrinkles occur in the lips as the age increases. This is due to intradermal dermal degradation, i.e., structural changes in the deep part of the skin that will lose its activity. Therefore, not only the wrinkles, but also lose their original solidity, gradually loosened, and the lips are struck. Therefore, for general consumers, there is a need to add more protection and moisturizing functions to the lipstick on the market, and the ability to improve wrinkles.

Accordingly, there is a need to develop a cosmetic composition for protecting lips that is excellent in the effect of moisturizing the lips and improving the wrinkles of the lip.

The inventors of the present invention have conducted intensive researches to overcome the problems of the prior art. As a result, they have found that the use of natural ceramide and rosehip fruit oil, which are excellent in skin barrier protection and moisturizing effect, The present invention has been accomplished by confirming that it is higher than when it is used alone.

Accordingly, an object of the present invention is to provide a lip cosmetic composition containing natural ceramide and rose hip oil as an active ingredient.

According to an aspect of the present invention, there is provided a lip cosmetic composition containing natural ceramide and rose hip oil as an active ingredient.

In the present invention, the cosmetic composition is characterized by improving moisturization of the lips and wrinkles of the lips.

In the present invention, the natural ceramide may be ceramide 3. [

In the present invention, the mixing ratio by weight of the natural ceramide and the rosehip fruit oil is 1:10 to 10: 1.

In the present invention, the cosmetic composition may further comprise a pigment.

In the present invention, the cosmetic composition is characterized by having a formulation selected from the group consisting of lipgloss, lip balm, lip balm and lipstick.

The ingredients contained in the cosmetic composition of the present invention include, in addition to the above-mentioned natural ceramide and rose hull fruit oil, the ingredients commonly used in cosmetic compositions, and they are commonly used in cosmetic compositions such as antioxidants, stabilizers, solubilizers, vitamins, Phosphorous additive, and carrier.

The cosmetic composition for lip care containing the natural ceramide and rose hip oil as an active ingredient of the present invention is a biocompatible lip care composition including a lip skin-like structure material, exhibits excellent lip skin moisturizing and lips skin barrier function recovery upon application to the lips, Has a synergistic effect in improving moisturizing and elasticity and improving lip wrinkles, and has an excellent lip protecting effect.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, these embodiments are only for illustrating the present invention, and thus the scope and scope of the present invention are not limited by these embodiments.

The present invention provides a lip cosmetic composition containing natural ceramide and rose hip oil as an active ingredient.

The outermost surface of the human skin consists of keratinocytes in which the mature keratinocytes are differentiated from the basal layer and degenerated. These keratinocytes are bound by ceramide double stranded lamellar structure, which is present in the stratum corneum, to maintain a smooth and elastic skin.

The ceramide contained in the cosmetic composition of the present invention is one of the skin structural lipids which is present in the stratum corneum of the skin surface layer and occupies about 40-50% of the interstitial interstitial lipid component. These ceramides form a multilamellar structure between the keratinocytes together with other keratinocyte lipid components, thereby suppressing moisture evaporation from the skin and maintaining moisture, thereby softening the skin and keeping the skin healthy.

Ceramides also function as a moisture barrier to prevent external leakage of moisture other than a skin barrier function that prevents the penetration of external stimuli. When the amount of ceramide is reduced in the skin, the barrier of the skin is not perfect and the skin becomes rough with loss of moisture in the body.

The natural ceramides according to the present invention may be selected from the group consisting of ceramide 1, ceramide 2, ceramide 3, ceramide 4, ceramide 5, ceramide 6, ceramide 7 and ceramide 8, And the above-mentioned natural ceramides provide skin barrier protection function, moisture retention function, stratum corneum protection function and the like.

The rosehip fruit oil contained in the cosmetic composition of the present invention is oil extracted from rosewood seeds of the Andes mountains of Chile and is excellent for improving symptoms such as burns, facial wrinkles and tissue regeneration effect, and is very useful for post-operative scar treatment.

The vitamin content of rosehip fruit is 20 times that of orange and 60 times of that of levon. It contains antioxidant to prevent aging. It helps the synthesis of collagen and helps to grow and recover tissue cells of bones, gums and teeth.

Beta-carotene, contained in rosehip fruit, is converted into vitamin A by the amount needed in the body, helping to regenerate and grow cells through antioxidant action associated with skin epidermal cells, eyes, digestive organs and respiratory organs. Such beta-carotene neutralizes the ultraviolet ray action and has an effect of blocking the inside of sunlight and a carcinogenic effect.

Rosehip fruit is a fruit of Rosaceae that grows mainly in Europe and South America and generally begins to bear fruit in the spring and matures in late summer or early autumn. Traditionally, it has been known to ingest 2-5 grams of powder per day, and its effects have been studied in a wide variety of ways, including antioxidant, anti-inflammatory, anti-obesity, antidiabetic, antimicrobial, Are known.

Lip is different from ordinary skin, keratin layer is very thin, there are differences in kinds of lipid components, especially skin protection ingredients, such as ceramides and free fatty acids are easily scarred because of a lot of ingredients, moisture is quickly evaporated and become rough and dry easily.

If the ceramide and vegetable oil as described above are supplied to the lips from the outside, the state can be greatly improved.

The dermis is a connective tissue under the epidermis. The dermis is not filled with cells as closely as the epidermis, but rather the extracellular space, which is filled by a macromolecular network called extracellular matrix. Over time, a portion of the cell adhered to the extracellular matrix gradually weakens and the compactness of the structure decreases with the total number of cells interacting. The three-dimensional structure of the tissue is also gradually degraded, and the ability of the fibroblast to synthesize and secrete the extracellular matrix is also reduced. That is, the skin loses elasticity.

Therefore, the lip cosmetic composition of the present invention, which is a mixture of the natural ceramide and the rosehip fruit oil, which are effective for skin barrier and moisture retention of the skin layer and the dermis layer in the outermost layer of the skin for protecting the lips, has a moisturizing effect on the lips, It is effective to improve the wrinkles of the lips by the increase of elasticity.

Further, according to the study by the present inventors, when the two ingredients are mixed together rather than when they are used alone, the effect of moisturizing the lips and improving the wrinkles of the lips are increased, which is effective for lips protection.

The cosmetic composition for protecting the lip of the present invention shows the use of lip protection through the enhancement of lip moisturization and the improvement of the wrinkles of the lip. Throughout the present specification, the term "lip protection" refers to protecting the lips by improving the condition of the lips by enhancing the moisturization of the lips, restraining wrinkle formation of the lips and improving the wrinkles produced.

According to a preferred embodiment of the present invention, the lip cosmetic composition containing the natural ceramide and the rosehip fruit oil together is superior in the moisturizing effect of the lip, the roughness of the lip and the wrinkle of the lip.

The mixing weight ratio of the natural ceramide and the rosehip fruit oil is not limited thereto, but may be preferably 1:10 to 10: 1. Outside of the above range, the synergistic effect in lip protection may be insignificant or the feeling of use may be deteriorated.

Meanwhile, the lip cosmetic composition according to the present invention may have a coloring effect by further containing a pigment. The pigments may contain from 0.1 to 20.0% by weight, based on the total weight of the composition, and the pigments are typically powders or coloring pigments such as silica, muscovite, synthetic mica, haze, kaolin, titanium dioxide, titanium oxide coated mica, .

The components contained in the lip cosmetic composition of the present invention include components commonly used in cosmetic compositions in addition to the active ingredients as active ingredients, and include conventional additives such as antioxidants, stabilizers, solubilizers, vitamins, , And a carrier.

The lip cosmetic composition of the present invention may be formulated into any formulation conventionally produced in the art and may be formulated into, for example, lip gloss, lip balm, lip balm and lipstick, but is not limited thereto.
