Abstract

The invention discloses a preparation method of a medical bacterial cellulose / non-woven fabric composite hydrogel facial mask. The preparation method is characterized in that non-woven fabric facial mask paper is immersed in fermentation liquid of bacterial celluloses and is subjected to static culture at a suitable temperature, and the bacterial celluloses are grown into fibers of the non-woven fabric facial mask paper in the fermentation process to form an interlaced interpenetrating network, so that the bacterial celluloses are closely compounded with the non-woven fabric facial mask paper.The invention further provides the medical bacterial celluloses / non-woven fabric composite hydrogel facial mask prepared by the method. The medical bacterial cellulose / non-woven fabric composite hydrogel facial mask disclosed by the invention is easy to spread and high in moisture content, has efficient adsorption / diffusion dual effects and can effectively absorb skincare essence. During the use,the composite hydrogel facial mask can efficiently release skincare components and keep good wettability.

Description

technical field [0001] The invention relates to the field of facial masks, in particular to a medical bacterial cellulose / non-woven composite hydrogel facial mask and a preparation method thereof. Background technique [0002] Mask is a carrier of beauty care products, which is divided into powder blending and mask paper (cloth) made of various fabric materials. The basic function of the mask is to expand the pores, promote skin metabolism, complete deep cleansing, moisturizing, whitening and other maintenance functions. The mask paper plays a role by absorbing the essence, and the different materials of the mask paper have a great influence on the function of the mask. At present, the better mask paper is biological fiber, followed by silk mask paper, followed by blended non-woven fabric. [0003] Bacterial cellulose is a cellulose hydrogel produced by microbial fermentation. It has a fine nanofiber 3D structure, which endows the material with various excellent properties...
