Problems solved by technology

The traditional washing mask does not form a film after drying, and cannot be lifted off as a whole, but can only be washed off with water, which is cumbersome to use and cannot continuously replenish water; Medical gypsum powder can quickly solidify after being mixed with water, and has the effects of astringent and accelerated local blood circulation, etc., but it is dangerous and requires professional guidance and operation, and it is not suitable for frequent use. In addition, it is not suitable for people with skin trauma; Powdered facial mask, after being made into a uniform paste, is applied on the skin to form a soft film. It is mild in nature, but it is cumbersome to use. It must be reconciled with water, and the water content is small. Function; the paste mask is a mask that has been adjusted by the manufacturer. It is easy to use, moisturizes, can adjust the thickness, and can also be used locally. It has strong astringency, but the paste mask usually contains a lot of powder, which may clog pores. It prevents the skin from breathing normally, and needs to be washed with water, which is inconvenient to use
The peel-off mask can clean up blackheads, dirt, dander, etc. on the skin, but this mask is extremely sticky, it is painful when peeled off, and it will enlarge the pores and cause damage to the skin
The stick-on mask is to cut the non-woven fiber fabric into the shape of the human face and put it in the packaging bag, and then pour the essence to seal the packaging bag. The non-woven fabric is impregnated with the essence to become a finished mask, just unpack it It is more convenient to use, but when this type of mask is used, the essence will drip when the non-woven fabric is taken out of the package. In addition, the non-woven fabric is very thin, the water retention capacity is insufficient, and the absorption of the essence is small, causing beauty problems. Waste of active ingredients, and limited adhesion of wet non-woven fabrics, easy to fall off on the face

Abstract

The invention relates to a hydrogel base material of a facial mask. The hydrogel base material is prepared by mixing 10% polyvinyl alcohol, 10% polyvinyl pyrrolidone, 2% chitosan liquid and an additive, and concretely comprises: 6-10 parts of 10% polyvinyl alcohol, 4-6 parts of 10% polyvinyl pyrrolidone and 0-5 parts of 2% chitosan liquid; the additive consists of 0.02%-0.03% of EDTA (Ethylene Diamine Tetraacetic Acid), 0-1% of methyl parahydroxybenzoats and 2%-5% of glycerinum based on the mass of the base material, as well as a proper amount of a pH regulating agent. Compared with a conventional facial mask, the hydrogel facial mask can be greatly absorbed, moisture and essential components are retained, so that hydrogel facial mask is unlikely to evaporate and dry, and the moisture and nutrients can be replenished continuously; and furthermore, the essence is all retained on the hydrogel, no essence is leaked, and the hydrogel facial mask is convenient to use.
