Cassava starch hydrogel nostoc commune extract mask matrix and preparation method thereof

Abstract

The invention discloses a cassava starch hydrogel nostoc commune extract mask matrix and a preparation method thereof. By adopting a modern polymer synthesis technology, a fine chemical technology and the principle of natural organic chemical extraction, ultrasonic dispersion is adopted to perform cassava starch gelatinization treatment, and then crosslinking modification is performed to prepare cassava starch hydrogel; antioxidative protein is extracted from nostoc commune by adopting natural organic extraction, extraction and other methods, is wrapped by the hydrogel by adopting an adsorption method and then is processed into the mask matrix having oxidation resistance, scavenging free radicals and having high water retention, water supplementing activities and the like. The cassava starch hydrogel nostoc commune extract mask matrix prepared by means of the preparation method is stable in performance, has the characteristics of high water retention and water binding capacity of the hydrogel, also contains organic active substances of a nostoc commune extract and has the multiple effects of oxidation resistance, tumor resistance, virus resistance, bacterial resistance and inflammatory resistance. In addition, the mask matrix is simple in preparation process, good in biocompatibility, easy to degrade and environmentally friendly.

Description

technical field [0001] The present invention relates to a natural polymer synthesis and fine chemical process treatment method and a natural organic chemical extraction process, in particular to a method under ultrasonic conditions with the extract of Dipis radiata as the main bioactive component and cassava starch hydrogel as the carrier Mask matrix and preparation method thereof. Background technique [0002] There are various classification methods for hydrogels, which can be divided into physical gels and chemical gels according to the different bonding of the hydrogel network. Physical gels are formed by physical forces such as electrostatic interactions, hydrogen bonds, chain entanglements, etc. This gel is non-permanent and can be converted into a solution by heating the gel, so it is also called pseudogel or thermal gel. Reversible gel. Many natural polymers are in a stable gel state at room temperature, such as k2-type carrageenan, agar, etc.; among synthetic poly...

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
