Abstract

The invention relates to a preparation method for a nano-crystalline cellulose mask containing a plant extract. The method comprises the following steps: adopting an ultrasonic soaking extracting method for acquiring an extracting solution containing plant active ingredients, screening, domesticating and optimizing by utilizing acetobacter gluconicum, thereby acquiring a high-producing strain; taking the optimized strain and inoculating into a sterilized culture medium; uniformly pouring an inoculated culture medium into a mask mold; treating and then acquiring a white transparent nano-crystalline cellulose mask matrix; sealing and packaging the mask matrix, sterilizing under high pressure, acquiring a biological cellulose wet film and then soaking in the sterilized plant extract; and directly putting the mask matrix into a refrigerator after the mask adsorption reaches a saturated state, freezing and then performing vacuum drying for 24h, thereby acquiring the nano-crystalline cellulose mask containing a plant extract. The production technology according to the invention is simple and convenient in operation, pollution-free, high in yield and capable of greatly reducing production cost.

Description

technical field [0001] The invention relates to a preparation process of a series of bionanocellulose and natural plant facial masks. It mainly develops a series of bionanocellulose and functionalized facial masks from the perspectives of fermentation production, structure regulation, and in-situ compounding. Background technique [0002] The biological cellulose facial mask uses biological fiber as the medium of the facial mask. Nano-scale fibers start from the surface of the culture liquid, and are densely woven sequentially from top to bottom toward the bottom of the incubator, forming a structure with a gradient density. Nano-level fibers are much smaller than skin pores, which can help the essence to be introduced more effectively and allow the mask to fit the skin completely. In addition, the gradient density structure of the biocellulose mask can effectively absorb up to 92.7% of the excess oil in the skin, export the oil in the pores, and achieve the purpose of repl...
