Description

Skin Mask Pack {MASK PACK FOR SKIN}

The present invention relates to a skin mask pack, and more specifically comprises 0.0001 to 0.1% by weight of calcium lactate, 0.0001 to 0.1% by weight of zinc acetate, 0.0001 to 0.1% by weight of urea and 0.0001 to 0.1% by weight of protease. It relates to a skin mask pack comprising a cosmetic composition.

In general, human skin is an organ that is susceptible to changes with age and eyes. The magnitude of the change is large and varies from part to part. In addition to the pathological changes in the skin such as senile pigment, alum, and hemangioma, the skin may also undergo various cosmetically unfavorable changes such as decreased skin gloss or gloss, reduced smoothness, decreased elasticity, and pigmentation. One of the major areas of research on skin aging is the study of changes in skin wrinkles.

Skin aging is known as the first and greatest factor in our body. These skin aging may appear naturally with age, but may be caused by exogenous stimulating factors. In particular, most of these exogenous stimulating factors are known as continuous exposure to ultraviolet light. Skin that has been exposed to ultraviolet rays for a long time decreases the size and number of capillaries and reduces the ability to carry various nutrients and oxygen, and causes wrinkles because wrinkles are not reproduced. Beginning at age 25, they appear on the face, neck, and other parts of the body, such as around the eyes, forehead, and around the mouth, and rapidly increase and deepen after the forties.

As such, the greatest influence on skin wrinkle formation is known as the change in collagen protein content, which is present in the dermal layer of the skin and accounts for about 70-80% of the total dry weight of the skin. Collagen protein, together with elastic fiber elastin, is known to control skin elasticity. Recently, research has been actively conducted to increase skin density in the epidermal and dermal layers of collagen protein and elastin that affect skin wrinkles using various agonists. In addition, research on the improvement of wrinkles has been progressed in various ways for the formulation or cosmetic method for maximizing the effect as well as the expression of efficacy by the ingredients.

In particular, the herbal patch therapy is one of the traditional Chinese medicine therapies for attaching gauze or cotton, paper, etc., containing a chemical solution to the affected part, and is often applied in connection with skin. In modern times, herbal paste composed of a coating agent and adhesive cloth is used to improve the blood flow and to relieve pain and stiffness by applying the heat treatment effect and the efficacy of the herbal medicine, and by taping therapy (tease therapy) Non-drug therapy is applied to the meridians and acupuncture points to smooth the flow of blood donation through stimulation by tape. However, patches, masks, tapes, etc. have been used to combine the efficacy of drugs with physical therapy, and are mainly used for pain and stiffness, muscles and ligaments, and for skin that can produce the most effective effect. It is not yet widely used.

In this regard, Korean Patent No. 815182 discloses a mask sheet containing metal nanoparticles and microbial cellulose, and presupposes the use of gold as a metal, which is intended to exhibit antimicrobial efficacy.

The said content can also exhibit the skin improvement effect which concerns on this invention.

The mast pack according to the present invention is a non-woven fabric prepared in the form of a face sheet, an eye pack form, a square or circular mask sheet or the like by adding a suitable crosslinking agent to the composition using a conventional method known in the art, A mask sheet such as a hydrogel can be prepared by sufficiently depositing the composition.

The mask pack according to the present invention can provide a more effective wrinkle improvement through the addition of a intensive management effect such as a shielding effect and cumulative absorption over time. Therefore, the mask pack according to the present invention includes both the wet (wet type) or hydrogel (hydro gel) formulation.

The wet type is another name for an essence type mask, and refers to a product in which a latex or a lotion is moistened with a nonwoven fabric. In general, the emulsion (wet type) of the mask pack or the lotion is similar to the manufacturing method of the general skin care essences, it is prepared by impregnating the pre-prepared essence in the cut non-woven fabric in the desired design.

The hydrogel formulation may be divided into a crosslinking type and a noncrosslinking type. The crosslinkable aqueous gel mask pack is a generic name for a product coated on a nonwoven fabric with the contents of a crosslinkable aqueous gel formulation having a predetermined shape, and generally has adhesiveness to skin. The crosslinkable aqueous gel mask pack is crosslinked with polyacrylic acid and neutralized polyacrylate-based polymers by adding a crosslinking agent (eg, aluminum glycinate, aluminum hydroxide, etc.) to prepare an aqueous gel formulation and then coating the nonwoven fabric. To complete the product.

The non-crosslinked aqueous gel mask pack is a generic name for a product in which the contents of a non-crosslinked aqueous gel formulation having a predetermined shape are coated on a support or in a state in which there is no support. Adsorption by moisture is applied to the skin. Typically, non-crosslinked aqueous gel mask packs are made of a mixture of natural gums (such as cellulose, xanthan gum, carrageenan, locust bean gum, etc.) that can hold large amounts of water, and agar that maintains a certain shape. The prepared contents are coated on a support (eg, polyester nonwoven fabric, Hanji, cellulose, etc.) or coated to a certain thickness without the support to complete the product. Generally gelatin, agar, cellulose, starch and the like are used.

In order to prepare the mask pack according to the present invention in the formulation, the composition may include a thickener material such as polyacrylate, gelatin, agar, cellulose, polyacrylate and starch in an amount of 0.01 to 5% by weight based on the total weight of the composition. have. When included in the above range, it can be efficiently cast in the form of a mask pack by maintaining a suitable viscosity, and properly supported so that the active ingredient penetrates well when the mask pack is placed on the skin, providing adequate flexibility and elasticity It provides excellent mask pack fit. More preferably, 0.1 to 3% by weight of the total weight of the composition is included in order to obtain optimal strength and skin fit.

In addition, according to the present invention, the skin mask pack may exhibit an optimal effect when the microporous cellulose is mixed with the cosmetic composition to form a mask sheet, or when the cosmetic composition is deposited on the microbial cellulose mask sheet.

The microbial cellulose is inoculated into a production strain, preferably a strain of genus Acetobacter, into a microbial cellulose production medium, preferably a fruit juice containing acetic acid and sugar, and cultured in a shake culture or an air lift fermenter. The microbial cellulose in the form of particles or pellets is produced in a dispersed form. The culture medium itself is used as a supernatant, inoculated into the culture medium for producing microbial cellulose, followed by stationary culture, and then a semi-transparent gel state microbial cellulose is produced. Since the semi-transparent gel-like microbial cellulose prepared as described above contains a medium component and a microorganism therein, it is immersed in water, washed, and then heated to prepare gel-like microbial cellulose from which impurities are removed. The gel microbial cellulose is compressed using a sponge in a pneumatic press to produce a wet sheet of a suitable thickness.

The total thickness of the prepared mask pack is generally preferably 0.001 to 0.5 cm. When it falls within the said range, it contains a potent substance suitably and provides it to skin, and it is preferable because there is little burden on skin. If the thickness of the mask pack is thinner than the above range, it may not contain enough of the useful ingredients of the present invention and may be torn or damaged during use, and if it is thicker than the above range, the weight of the mask pack is increased to the skin. There is a burden when using it.

Among the above formulations, the use of an exclusive dressing method is more preferable because it effectively delivers useful ingredients to the skin and subcutaneous tissue.

According to the present invention, the composition is characterized in that it comprises zinc stearate, urea and protease in a ratio of 50 to 150 parts by weight with respect to 100 parts by weight of calcium lactate. When contained within the range of the ratio, the effect of improving skin elasticity and wrinkles appears most effectively, and is also preferable in terms of formulation stability and skin irritation.
