Abstract

The invention relates to a hydrogel mask preparation method as well as a product and the application thereof. An electrostatic spinning mode is adopted, a fibroin fiber membrane of antibacterial nanoparticles is prepared, then fibroin fibers and sugarcane hydrolysate are co-fermented, bacterial fibers and the fibroin fibers are compounded and crosslinked, and the composite hydrogel mask is obtained. By adopting an electrostatic spinning mode, the nano antibacterial particles are directly woven into fibers, so that the mask base material has antibacterial ability, no additional antibacterial component is needed when the beautifying component is added, and the shelf life of the mask is prolonged. Through the subsequent co-culture fermentation of the fibroin fiber membrane and the sugarcane fermentation liquor, the bacterial cellulose and the fibroin fiber are compounded and cross-linked, so that the hydrogel mask base material is prepared. After the hydrogel mask base material adsorbs beautifying active ingredients rich in sugarcane extracts, a hydrogel mask can be obtained, and the mask has the effects of whitening, moisturizing, diminishing inflammation and promoting fibroblast growth.

Description

technical field [0001] The invention relates to a preparation method of a hydrogel facial mask and its product and application. Specifically relates to a preparation method of bacterial cellulose / silk fiber composite hydrogel facial mask prepared by electrospinning and fermentation processes. The invention belongs to the technical field of cosmetics. Background technique [0002] The improvement of living standards has prompted more people to pay attention to the beauty field. Among them, facial mask is a product for facial skin care and beauty. Because of its convenient use and remarkable effect, it has attracted the attention of beauty lovers and has been widely recognized in the market. Traditional facial masks are usually stick-type, mud-cream-type, etc. These types of facial masks usually contain beautifying liquids, which use their direct contact with the face to promote the nutrients in the mask to enter the stratum corneum of the skin surface to achieve moisturizing...
