Description

COSMETIC COMPOSITION FORMING BREATHABLE PROTEIN MEMBRANE THAT EFFECTIVELY ABSORBS ACTIVE INGREDIENT WHILE BLOCKING MOISTURE EVAPORATION OF SKIN}

The present invention relates to a cosmetic composition, and more particularly, to overcome the limitations of cosmetics applied to the skin, it forms a breathable protein film when applied to the skin to effectively absorb active ingredients and inhibit moisture evaporation of the skin. It relates to a cosmetic composition that forms a breathable protein membrane that effectively absorbs active ingredients while blocking.

The skin is an organ that has a protective function, a barrier function, a temperature control function, an excretory function, a respiratory function, and the like, and consists of the epidermis, dermis and subcutaneous fat. The epidermis is the thinnest layer and consists of organic bonds between keratinocytes and melanocytes. The dermis accounts for about 95% of the skin and is a layer responsible for moisturizing and protecting the skin. Collagen and elastin, which are representative proteins that play an important role in skin elasticity (wrinkles), are distributed like a net, and blood vessels and nerves exist. It also contains mast cells involved in allergic reactions, and natural moisturizing factors such as Na-PCA or hyaluronic acid.

Subcutaneous fat plays the role of supplying nutrients to the epidermis and dermis, determining body shape, maintaining body temperature, absorbing external shocks, and protecting cells under the subcutaneous fat.

The stratum corneum of the epidermis, which is the outermost layer of the skin, serves as a barrier against external harmful environments and plays an important function of preventing moisture evaporation of the skin. Dry skin is caused by an increase in transepidermal water loss (TEWL) due to an abnormality in the skin barrier due to a lack of moisture in the stratum corneum.

However, the conventional cosmetic composition is applied and used in a form that is simply applied to the skin of the human body. In this case, no matter how effective a material is used, if the active ingredient does not penetrate into the skin and stays outside the skin, the effect cannot be properly exhibited. .

That is, since the skin of the human body acts as a barrier to effectively protect the human body from external stimuli, the active ingredient of the cosmetic composition is also not easily absorbed.

Therefore, recently, research to develop a cosmetic composition that can promote absorption of active ingredients without irritating the skin is being actively conducted.

Glycerin is added together with xanthan gum as a thickener to control the viscosity of the membrane. Such glycerin is preferably added in an amount of 0.5 to 1.5% by weight of the total weight of the cosmetic composition of the present invention, and 0.8 to 1.2% by weight may be presented as a more preferred range.

When the amount of glycerin added is less than 0.5% by weight, there may be a problem of thinning due to low viscosity. Conversely, when the amount of glycerin added exceeds 1.5% by weight, the viscosity is excessively high, so that usability is reduced, and there may be a problem in that the formulation is not stable.

Cetearyl alcohol works with xanthan gum and glycerin to act as a thickener and binder to control the viscosity of the liquid film and prevent evaporation and absorption from the skin of the film while drying, preventing moisture evaporation from the skin. It seals the skin by maintaining a solid film on the skin surface.

Such cetearyl alcohol is preferably added in an amount of 0.5 to 1.5% by weight of the total weight of the cosmetic composition of the present invention, and 0.8 to 1.2% by weight may be presented as a more preferred range.

When the amount of cetearyl alcohol added is less than 0.5% by weight, it may be difficult to properly exhibit the effect of preventing moisture evaporation.

Such caffeine is preferably added in an amount of 0.5 to 12% by weight of the total weight of the cosmetic composition of the present invention, and may be present in a more preferred range of 9 to 10% by weight.

When the amount of caffeine added is less than 0.5% by weight, the lipolytic effect is low. Conversely, when the amount of caffeine added exceeds 12% by weight, the amount of niacinamide required for dissolution is excessively large, and even if dissolved, it is vulnerable to nucleation due to local moisture evaporation on the wall of the container when left for a long period of time. There is a risk that precipitation may be induced.

Sodium hyaluronate (sodium hyaluronate) is a representative material having the functions of wrinkle improvement and anti-aging. This sodium hyaluronate acts as a moisturizing agent that doubles the skin barrier by forming a moisturizing film on the inside and outside of the skin.

The ethylhexyl glycerin is preferably added in an amount of 0.2 to 0.7% by weight of the total weight of the cosmetic composition of the present invention, and a more preferred range may be 0.4 to 0.6% by weight.

When the amount of ethylhexylglycerin added is less than 0.2% by weight, the amount added is insignificant and it is difficult to properly exhibit the antiseptic effect. Conversely, when the amount of ethylhexylglycerin added exceeds 0.7% by weight, the increase in the preservative effect is insignificant compared to the increased amount, and it is not preferable because it acts as a factor to reduce the amount of other components used.

Lysine is responsible for moisturizing, cell proliferation, promoting collagen synthesis, improving skin elasticity and skin wrinkles. This lysine is added together with proline to help collagen production, helping to maintain healthy and elastic skin. Therefore, lysine is preferably added in an amount of 0.00001 to 0.00020% by weight of the total weight of the cosmetic composition of the present invention, and 0.00010 to 0.00015% by weight may be presented as a more preferred range.

At this time, the breathable protein membrane adheres to the skin, penetrates the active ingredient deep into the skin, and suppresses moisture loss from the skin.

This will be described in more detail below with reference to the accompanying drawings.

1 is a view for explaining a mechanism of forming a breathable protein membrane when a cosmetic composition according to an embodiment of the present invention is applied to the skin, and FIG. 2 is a view for explaining the breathability when the cosmetic composition according to an embodiment of the present invention is applied to the skin.

In general, when a cosmetic composition is applied to the skin of the human body to form a film, if the film is strengthened, the moisturizing agent is sufficiently supplied and the moisturizing film is perfectly formed, but the drying time is delayed or the adhesion to the skin is increased, which stimulates the removal of the film. There is a disadvantage in that this occurs or the membrane breaks. On the other hand, if the film strength is weak, the drying time can be shortened and irritation can be reduced, but the formation of the moisturizing film is weakened and the supply of the moisturizing agent components is insufficient.

However, in the cosmetic composition according to an embodiment of the present invention, the acrylate/C10-30 alkyl acrylate crosspolymer, which is an acrylic acid-based anionic water-soluble high molecular compound, forms a thin film together with the sodium acrylate copolymer. At this time, the acrylate/C10-30 alkyl acrylate crosspolymer formed by cross-linking increases the elasticity of the membrane to seal the skin without gaps, and since it is formed based on two acrylate components, moisture and oil are blocked. It is possible to have breathability that allows only the air in the atmosphere to pass through.

As a result, according to the present invention, the breathable protein membrane does not penetrate into the skin of the human body and provides sufficient nutrition and moisturizing effect to the skin, corrects skin sagging, and maintains elasticity.

Accordingly, in the present invention, when the cosmetic composition is applied to the skin of the human body and dried, a breathable protein film that is perfectly in close contact with the skin is formed to suppress the evaporation of moisture from the skin of the human body, and to fundamentally restore the damaged skin barrier to treat atopic dermatitis. effective.

In addition, since the present invention forms a transparent silicone type skin protective film by combining acrylate/C10-30 alkyl acrylate crosspolymer and sodium acrylate copolymer, a conventional cosmetic composition is applied to the human skin in a state of being applied thereon. When used in this way, it can exert a booster effect that radiates radiantly like water-glow skin.
