Embodiment 1

[0044] A silk mask doped with cellulose nano whiskers, the preparation method of which is as follows:

[0045] (1) The silk raw material was added into water at 95°C for 1 hour, the mass ratio of silk to deionized water was 1:1, and alkali treatment was performed after centrifugal dehydration. The centrifugation is carried out with a flat plate centrifuge, and the centrifugation conditions are as follows: the rotating speed is 3000rpm, and the centrifugation time is 15min. The alkali treatment is specifically: immersing the silk in 80° C. with a mass fraction of 0.1% Na 2 CO 3 In the solution, after reacting for 30 minutes, wash it with 80°C deionized water, and then add 80°C, 0.1% Na 2 CO 3In the solution, react for 30 minutes, repeat once, and wash the obtained silk fiber until it is neutral; wherein the mass ratio of silk to sodium carbonate is 100:1.

[0046] (2) Mix Alealase 2.4L enzyme into the silk fiber obtained in step (1), stir and disperse evenly at a rotating s...

Embodiment 2

[0049] A kind of silk mask containing cellulose nano whiskers, its preparation method is as follows:

[0050] (1) Add silk raw materials into water at 95°C for 3 hours, the mass ratio of silk to deionized water is 1:100, and carry out alkali treatment after centrifugal dehydration. The centrifugation conditions are as follows: the rotation speed is 3000 rpm, and the centrifugation time is 15 minutes. The alkali treatment is specifically: soaking the silk at 85°C with a mass fraction of 10% Na 2 CO 3 In the solution, after reacting for 60 minutes, wash it with 85°C deionized water, and then add 10% Na at 85°C again. 2 CO 3 In the solution, react for 60 minutes, repeat the execution 5 times, and wash the obtained silk fibroin fiber to neutrality. Wherein the mass ratio of silk and sodium carbonate is 100:10.

[0051] (2) Mix Alealase 2.4L enzyme into the silk fiber obtained in step (1), stir and disperse evenly at a rotating speed of 200r / min, and add enzyme at a temperatur...

Abstract

The invention discloses a preparation method of a cellulose nano whisker-doped silk paper and an application of the silk paper in a mask. The preparation method comprises the following steps: 1) pre-processing silk with hot water and performing centrifugation to remove moisture, performing alkali treatment, cleaning the material to neutrality to obtain fibroin fiber; 2) adding protease in the fibroin fiber obtained in the step 1), uniformly stirring and mixing the materials and performing enzymatic hydrolysis, and inactivating fibroin slurry after enzymatic hydrolysis to obtain the inactivatedfibroin slurry; and 3) adding the cellulose nano whisker in the inactivated fibroin slurry obtained in the step 2) for paper making to obtain the cellulose nano whisker-doped silk paper. The silk paper is dipped to elite liquid to obtain a silk mask, the silk mask has good permeability and flexibility, and excellent water-retaining property and adsorbability, and is capable of deeply supplementing water, removing wrinkle and whitening skin.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a preparation method of silk paper doped with cellulose nano-whiskers and its application in facial masks. Background technique [0002] With the development of society and the advancement of science and technology, people's living standards have improved, and pressure has also followed. With the pressure, the skin loses its luster and does not have good smoothness. Therefore, more and more women are interested in Beauty care products are becoming more and more popular. Mask has become the most important part of skin care because of its high nutritional content and remarkable skin care efficiency. The principle of the mask is to use the short time covered on the face to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote the secretion and metabolism of sweat glands, increase the oxygen content of the ...
