Description

Hydrogel for mask pack, bio-glucose mask pack using same, and manufacturing method thereof {Hydrogel for mask pack Bio glucose mask pack using the same and Manufacturing thereof}

The present invention relates to a hydrogel for a mask pack prepared from natural ingredients, a bio-glucose mask pack using the same, and a method for manufacturing the same.

The skin protects the body, contains nerve endings that can be felt when stimulated from the outside, and is also responsible for chemical and physical reactions such as thermoregulation and vitamin synthesis.

The skin is largely divided into epidermis, dermis, and subcutaneous tissue. The dermis contains more water than the epidermis and provides nutrients to the epidermis. When the epidermis lacks nutrients or moisture, the dermis supplies moisture and nutrients, so it is necessary to protect the skin and supply moisture so that the epidermis layer does not lose moisture from the outside. If moisture supply is not smooth, skin dryness occurs and the binding force of keratinocytes decreases, providing nutrition to the moisture balance of the epidermis and dermis, including the stratum corneum. In order to reduce these effects, it is necessary to protect the skin and provide sufficient moisture and nutrition to maintain healthy skin. In particular, since the skin is a visible part and takes up a lot of weight in determining aesthetic beauty, it is essential to maintain skin moisture.

If the skin lacks moisture, most people say that the skin is dry. However, dry skin is not necessarily caused by a decrease in skin moisture content. It has been reported that drying of the skin is improved by frequently applying a moisturizer when the skin feels dry.

A mask pack is a kind of cosmetic that restores the physiological function of the skin by covering the skin surface and supplying moisture and beauty ingredients to the skin. In general, the mask pack is prepared by impregnating the sheet layer with a skin care component, and by attaching it to the skin surface for a certain period of time, the impregnated skin care component can be effectively absorbed into the skin.

Mask packs can be used not only on the face but also on the whole body, and there are non-woven fabrics and hydrogel-type masks. Hydrogels exhibit a structure similar to the cell matrix of the human body and are inert and have excellent elasticity, and excellent permeability of oxygen and nutrients, thereby exhibiting excellent biocompatibility, thereby increasing interest in the pharmaceutical and cosmetic industries.

In the cosmetic field, various cosmetic compositions that can enhance moisturizing, nourishing, or exfoliating effects by using the elasticity, skin adhesion, moisture retention, and soft touch of a hydrogel are continuously being developed. The hydrogel type mask pack is manufactured and distributed in the form of a sheet by putting a hydrogel matrix between the upper and lower two films. In the case of a conventional hydrogel type mask pack, since the surface of the hydrogel sheet layer is a flat two-dimensional form, the hydrogel The surface becomes slippery by the foreign matter flowing out from the matrix, and the hydrogel may be pushed out from between the upper and lower films, so there was a problem that the production yield was significantly lowered, and the quality was also deteriorated in terms of texture. In conventional hydrogel mask packs, not only the production yield is significantly lowered during molding due to the hydrogel's syneresis and surface properties, but also the adhesion to the skin is reduced due to the slip phenomenon caused by the syneresis, so the active ingredients contained in the mask pack There was a problem in that the transmittance of the drug was insufficient and the amount of impregnation of the cosmetic as an active ingredient was small.

Therefore, there is a need for the development of a hydrogel mask pack capable of greatly increasing the amount of impregnation of a cosmetic, which is an active ingredient for skin improvement, while having excellent flexibility and adhesion when applied to the skin, along with high absorption and moisturizing power.

At this time, if the stirring speed is out of the above range, there may be a problem in that the matrix structure is insufficiently or non-uniformly formed. And, if the secondary thermal crosslinking treatment temperature is less than 105 ℃, there may be a problem that the matrix structure in the hydrogel is insufficiently formed, and if it exceeds 120 ℃, there may be a problem that the matrix structure in the hydrogel is rather non-uniform.

In step 2-3, the third thermal crosslinking treatment may be performed at 400 to 800 rpm and at 80 to 90° C. for 5 to 10 minutes, preferably at 400 to 600 rpm and at 80 to 85° C. for 5 to 8 minutes.

In this way, a three-step multi-stage thermal cross-linking treatment can be performed to form a hydrogel having a three-dimensional matrix structure.

Next, step 3 is a process of impregnating (penetrating) the skin improvement cosmetic, which is an active ingredient, into the hydrogel, and after putting the skin improvement cosmetic into the reactor in which the hydrogel is formed, under 800 ~ 1,200 rpm for 5 ~ 15 minutes , Preferably, the skin improvement cosmetic is dispersed and impregnated in the hydrogel for 5 to 15 minutes under 800 to 1,000 rpm.
