Embodiment 1

[0044] A preparation method of bacterial cellulose facial mask, comprising the following steps:

[0045] A. Dissolve 3 mL of 6-carboxyfluorescein into 12 mL of N,N-dimethylformamide to obtain a 6-carboxyfluorescein solution;

[0046] B. Add 20mg of N,N,N',N'-tetramethyl-O-(N-succinimidyl)urea tetrafluoroborate to 4mg of N,N-diisopropylethylamine , mixed evenly and added to the 3 mg 6-carboxyfluorescein solution in step A, and left at room temperature for 40 minutes to obtain a 6-carboxyfluorescein mixed solution;

[0047] C. Dissolve 30mL of 1,3,4,6-tetra-O-acetyl-2-amino-2-deoxy-β-D-glucopyranose hydrochloride in 3mL of nitrogen-containing organic solvent to obtain 1 , 3,4,6-tetra-O-acetyl-2-amino-2-deoxy-β-D-glucopyranose solution, the nitrogen-containing organic solvent consists of N, N-diisopropylethylamine and N , N-dimethylformamide is composed according to the volume ratio of 1:1;

[0048] D. Mix 28 mL of 1,3,4,6-tetra-O-acetyl-2-amino-2-deoxy-β-D-glucopyranose solutio...

Abstract

The invention belongs to the field of masks, and concretely relates to a bacterial cellulose mask and a preparation method thereof. The method comprise the following steps: dissolving 6-carboxy fluorescein into N,N-dimethylformamide to obtain a 6-carboxy fluorescein solution; preparing N,N,N',N'-tetramethyl-O-(N-succinimidyl)urea tetrafluoroborate, N,N-diisopropylethylamine and 1,3,4,6-tetra-O-acetyl-2-amino-2-deoxy-beta-D-glucopyranose hydrochloride and other compounds to obtain an additive, adding the additive to a basal medium, and then inoculating the sucrose yeast, and culturing to obtaina bacterial cellulose sample; performing treatment with a 2% NaOH solution, washing with deionized water, and drying to obtain the bacterial cellulose mask. The bacterial cellulose mask of the present invention has a pore size of mostly between 10 and 20 nm, and the structure is extremely dense, which is much smaller than the diameter of fibroblasts, epithelial cells, and smaller than the diameter of most microorganisms. The bacterial cellulose mask has good bacteria resist performance, and prevents local wound adhesion.

Description

technical field [0001] The invention belongs to the field of facial masks, and in particular relates to a bacterial cellulose facial mask 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 are used more and more widely as cosmetics for cleaning, caring and nourishing facial skin, and become daily skin care products. Masks are becoming the new favorite of masks because they can be loaded with various skin care essences and are easy to use. The stick mask uses the short time covered on the skin surface to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote sweat gland secretion and metabolism, increase the oxygen content of the skin, and effectively eliminate skin toxins and accumulated oil substances, and quick...
