Description

Skin Adhesive Cosmetic Formulation Using Papyrus

The present invention relates to an active ingredient-containing skin adhesive cosmetic formulation that can be used to improve skin function.

Pack is originally meant to 'wrap' by wrapping the active substance on the face to remove pores and cleansing the skin effectively and supplying moisture and beauty ingredients to the skin to maintain blood circulation and restore skin physiology. It is a kind of functional cosmetics. Since the pack can provide various nutrients to the skin very effectively, it can be expected to have various effects such as moisturizing, soothing, aging, removing dead skin cells and wastes, restoring tired skin, enhancing elasticity and whitening by these cosmetic ingredients.

Natural ingredients such as herbal extracts, cucumbers, tangerines, aloe, carrots, mugwort, seaweed, ginseng, red ginseng, potatoes, cactus or plums to remove waste from such damaged skin, whiten, reduce wrinkles, moisturize or nourish Packed such as massage cream, nutrition pack, cleansing pack or whitening pack using.

In particular, various types of masks are cut and packaged in a circular or facial shape so that they can be covered with a non-woven fabric or a cosmetic film by impregnating various ingredients such as skin waste removal, wrinkle removal, and whitening for easy massage. Packs are already commercialized and marketed, and the demand for mask packs is increasing significantly because of their simplicity and convenience.

Conventionally, nonwoven fabrics or cotton have been used as a support for skin adhesive cosmetic formulations such as mask packs. Non-woven fabrics are made in a felt shape by arranging the fibers in parallel or in an opposite direction without going through a woven fabric process and combining them with a synthetic resin adhesive. Synthetic fibers such as cotton, viscose rayon, and nylon are used as raw fibers. It is the most widely used material among the bases of the skin adhesive cosmetic formulation because the fibers are entangled and have no lateral and transverse directions, and the cut edges do not loosen.

Non-woven fabrics are made of a method of drying and heat-treating fibers in a synthetic adhesive container, spraying synthetic resin on a thin cotton fiber, drying them by applying heat, and forming a physical bond or a chemical adhesive.

However, conventional skin-adhesive cosmetic formulations, such as mask packs based on nonwoven fabrics, are components obtained through chemical processes, which may cause skin problems when they come into contact with the skin, and do not easily rot in nature when disposed of, resulting in environmental pollution. There is this, and cotton is not suitable for disposable in terms of price. In addition, tissues such as tissues are easily released and cannot function as a mask. Accordingly, there has been a demand for the development of a skin adhesive cosmetic formulation of a natural material having excellent fit to the skin and no irritation at all.

An object according to an embodiment of the present invention is to provide a skin adhesive cosmetic formulation using a natural material excellent in fit to the skin, there is no irritation to the skin.

Skin adhesive cosmetic formulation according to the present invention for achieving this object is a support from a papyrus plant; And it is characterized in that it comprises a gel (gel) containing the active ingredient, applied on the support.

In addition, the method for producing a skin adhesive cosmetic formulation according to the present invention for achieving the above object (a) dissolving tartaric acid (Tartaric Acid) and prosthetic polymer in water, and correcting the evaporated water to prepare a solution; (b) Glycerin is an additive selected from the group consisting of acrylic acid, sodium polyacrylate, dihydroxy alminium aminoacetate, EDTA-Na, sodium CMC (sodium CMC: sodium CarboxyMethyl Cellulose) and preservatives. Dispersing; (c) dispersing the additive dispersed in the glycerin prepared in step (b) in the water portion of the solution of step (a) to prepare a crosslinked hydrogel; And (d) combining the active ingredient and the crosslinked hydrogel and loading the support on the papyrus plant-derived support.

Furthermore, the method for preparing a skin adhesive cosmetic formulation according to the present invention for achieving the above object comprises the steps of: (a) preparing a stirring solution by blending and stirring the active ingredient in the silicone portion comprising a crosslinking site; (b) applying the stirring solution of step (a) onto a support derived from a papyrus papyrus plant; (c) forming a silicone gel in which a silicone pressure-sensitive adhesive layer is formed on the support by passing through a heating device at 70 ° C. to 150 ° C .; And (d) cutting the silicon gel.

The skin adhesive cosmetic formulation according to the present invention has a papyrus having excellent hygroscopicity, breathability, and tensile strength as a support, and a gel containing an active ingredient is applied thereto, and thus, there is no irritation to the skin, thereby providing excellent skin fit.

The nonwoven fabric that has been used as a support for conventional skin adhesive cosmetic formulations has a weak tensile strength and cannot support a gel. However, in the present invention, by applying papyrus instead of the nonwoven fabric as a support for the skin adhesive cosmetic formulation, the weak tensile strength of the nonwoven fabric can be compensated for to carry a gel which the nonwoven fabric cannot support. In addition, the skin adhesive cosmetic formulation according to the present invention is excellent in hygroscopicity and breathability due to the inherent characteristics of the papyrus-derived plant, thereby minimizing irritation to the skin, it can exhibit an excellent fit.

The gel is not particularly limited as long as it is suitable for supporting the active ingredient, but may be, for example, a crosslinkable hydrogel or silicone gel.

The cross-linked hydrogel has good water washability and is not sticky, and is a nonfatty base that exhibits a certain level of roughness by swelling with water or other liquids, and has an advantage of being suitable for semi-solid preparations. In addition, it has excellent skin adhesion but can feel moist when worn.

The silicone gel has excellent adhesion, breathability, and fit, and when the silicone gel containing various active ingredients is attached to the skin, the active ingredient has excellent skin absorption, and is excellent for skin wrinkle improvement, whitening, moisturizing, blemish removal, blotch removal and slimming. It is a formulation that may contain an active ingredient that produces an effect.

In one preferred embodiment, the active ingredient-containing crosslinked hydrogel or silicone gel may be an active ingredient supported on the crosslinked hydrogel or silicone gel.

The papyrus is a perennial herb (多年生 草) growing in the water upstream of the Nile, reaching 6-7 m in length, the roots extending very deep, and the stem is triangular. The tip of the stem is flexible, the flower buds bloom at the terminal buds, and there are no nodes on the stem of the triangle, and there are only very short leaves at the base part. The papyrus flowers are decorative, the roots are hard to make various utensils, and the big plot can be used to make sailing boats, ropes, sandals, medicinal, baskets, fuel, etc. The close one can be used for making paper or for eating foods such as salads.

The support may be composed of the stem component of the cyperus papyrus plant, for example, by taking a cyperus papyrus plant and cutting it to about 30 cm in length and then peeling off the stem of the triangle of the triangle A white core can be obtained. The sliced sheet obtained by dividing the core into thin sections from the wide side is properly dried, soaked in water, and then beat with a bat (slice circle is not changed) so that 1-2 mm overlap each other.

Weight percent, 0.01-5.0 weight percent ivy extract or 0.01-5.0 weight percent fancy extract may be contained in the crosslinked hydrogel, respectively. The content range is based on the total weight of the composition, when the content range is 0.1% or less, the desired effect is insignificant, and when it exceeds 5.0%, phenomena such as dispersion and precipitation in the aqueous solution may occur.

The content range of the active ingredient can be formulated in a stabilized form, such as liposomes or encapsulation, in the limit of the notification content of the KFDA notice content, the efficacy can be recognized within this range. In addition, when the active ingredient is contained in less than the above-defined range, the effect is insignificant, and when contained in the above-mentioned range, it is difficult to disperse in the aqueous solution, precipitate in the aqueous solution, or cause skin irritation.

In one preferred embodiment, the thickness of the gel containing the active ingredient applied on the support is not particularly limited, but may be, for example, 0.001 to 2cm, preferably 0.001 to 1cm. Less than 0.001 cm is a thickness that is difficult to contain the active substance in an appropriate amount, the thickness of 2 cm or more may burden the skin, the thickness of the gel containing the active ingredient is within the range of 0.001 to 2 cm, preferably It may be 1 cm or less.
