Problems solved by technology

CN102525837A discloses the preparation of a bacterial cellulose film containing astaxanthin. The final formed mask is mechanically cut, which easily leads to the inhomogeneity of the film
[0007] The currently disclosed bacterial cellulose facial mask with skin-beautifying effects is mainly obtained by the bacterial cellulose gel mask obtained by placing Acetobacter xylinum in coconut water and adding nutrients. This type of membrane has a single structure

Abstract

The invention relates to a bacterial cellulose facial mask with a gradient structure and a preparation method of the facial mask. The preparation method comprises the following steps of: adding a thickening agent and crop starch in fermentation culture liquid, heating to dissolve and paste the thickening agent and the crop starch, uniformly dispersing the thickening agent and the crop starch in the culture liquid, carrying out static culture on the thickening agent and the crop starch, so as to prepare the bacterial cellulose facial mask similar to the skin of a human body and having the loose structure in which the compactness of the upper surface gradually transits to the lower surface. The bacterial cellulose facial mask has good water binding capacity and dragging resistance and an extremely high veneering degree, is biodegradable, ecologic and environment-friendly, is low in preparation cost and is simple and convenient to use and carry.

Description

technical field [0001] The invention relates to a bacterial cellulose mask with a gradient structure and a preparation method thereof, in particular to a bacterial cellulose mask with a loose lower surface whose upper surface is dense and continuously transitions downward and a preparation method thereof. Background technique [0002] With the progress of the times and the development of the economy, more and more people begin to pay attention to the maintenance of personal skin quality. Among them, facial masks have been recognized by more and more people as cosmetics for cleaning, caring and nourishing the facial skin. [0003] The principle of the facial mask is to form an airtight film on the facial skin first, isolate the skin from the outside world, increase the temperature of the skin, the pores will sweat a lot, and the secretion of the skin will be vigorous. When the mask is peeled off or washed off, the skin secretions, Squeeze out dandruff, dirt, etc. to clean the...
