Problems solved by technology

[0004] At present, the facial mask beauty products commonly used are mainly in the form of powder, mud and paste, which must be prepared according to certain requirements before use, which is extremely inconvenient to use
In recent years, the types and quantities of facial masks have been increasing, but the mainstream facial masks on the market are still mainly paper masks. This kind of facial mask is to immerse the prepared medicine in a paper carrier and apply it directly to the face when used. The mask is easy to use but its ductility is not good, and the performance of the mask is affected by a specific carrier, and the water holding capacity is poor

Abstract

The present invention discloses a preparation method for a biological cellulose composite membrane mask material. In the preparation method, water soluble macromolecular carboxymethyl cellulose is added into a culture medium, and then acetobacter xylinum is switched in for static culturing to obtain a biological cellulose composite membrane. The biological cellulose composite membrane generated after the carboxymethyl cellulose is added has good water retention property and good ventilation property, and the output and the water content of the biological cellulose composite membrane are improved to a certain extent. The biological cellulose composite membrane mask material can be obtained after the generated biological cellulose composite membrane is processed.

Description

Technical field [0001] The invention relates to a method for preparing a bio-cellulose composite film facial mask material, in particular to a method for preparing a bio-cellulose composite film facial mask material by adding carboxymethyl cellulose. Background technique [0002] Biocellulose is a kind of high molecular compound, similar to natural cellulose in structure, both are made of glucose connected by β-1,4-glycosidic bonds, and biocellulose has unique physical structure and properties, such as intricate The network structure, high crystallinity and high degree of polymerization, strong water retention and air permeability, excellent shape maintenance ability and tear resistance, no irritation, biocellulose diameter between 0.01 ~ 0.1μm, tensile strength High strength, high chemical derivatization activity, no lignin, hemicellulose, simple extraction process, high product purity. Therefore, the research and development of this new type of cellulosic material has attracted...
