preparation example Construction

[0034] A preparation method of fiber non-woven fabric for facial mask, comprising the steps of:

[0035] (1) Take silk and add 15-30 times the mass of silk with 4% Na 2 CO 3In the solution, stand at 90~100°C for 50~70min, filter, take the filter residue and dry it in an oven at 40~50°C for 20~24h to obtain degummed silk, take the degummed silk at a mass ratio of 1:15~25 and add reagent A to mix, Pour into a dialysis bag with a molecular weight cut-off of 10-14kDa, dialyze with deionized water for 4-6 days, take the dialysate and centrifuge at 2000-3000r / min for 5-10min, collect the supernatant to obtain pretreated silk fibroin protein solution;

[0036] (2) At 40~55°C, take the pretreated silk fibroin protein solution and add a crosslinking agent in a mass ratio of 100:1~4 to mix, and stir magnetically at 400~600r / min for 7~10h to obtain a crosslinked product. According to the mass ratio of 15~25:3~6:0.1, nano-hydroxyapatite liquid and auxiliary agent are mixed to obtain mo...

Embodiment 1

[0041] Cross-linking agent: take nijingping at a mass ratio of 1:12, and CaCl with a concentration of 0.03mol / L 2 The solutions are mixed to obtain the crosslinking agent.

[0042] Reagent A: Mix lithium bromide solution with a concentration of 3 mol / L and hexafluoroisopropanol at a volume ratio of 10:1 to obtain reagent A.

[0043] Reagent B: Mix 20% acetic acid solution with a mass fraction of 20% and PBS buffer with a pH of 6.3 at a volume ratio of 5:1 to obtain Reagent B.

[0044] Adjuvants: take dopamine hydrochloride and NaH at a mass ratio of 5:1:1 2 PO 4 、Na 2 HPO 4 Mix to get the adjuvant.

[0045] Nano-hydroxyapatite solution: Mix nano-hydroxyapatite, sodium citrate solution with a concentration of 1mol / L, and sodium bicarbonate at a mass ratio of 1:15:0.1 to obtain nano-hydroxyapatite solution.

[0046] Pretreatment of carp skin liquid: take carp skin, wash it with water 3 times the weight of carp skin, and dry it naturally to obtain dry matter. Take the dry m...

Embodiment 2

[0057] Cross-linking agent: Nijingin at a mass ratio of 3:12, CaCl with a concentration of 0.03mol / L 2 The solutions are mixed to obtain the crosslinking agent.

[0058] Reagent A: Mix lithium bromide solution with a concentration of 3 mol / L and hexafluoroisopropanol at a volume ratio of 10:1.5 to obtain reagent A.

[0059] Reagent B: Mix 20% acetic acid solution with a mass fraction of 20% and PBS buffer solution with a pH of 6.5 at a volume ratio of 5:1.5 to obtain Reagent B.

[0060] Adjuvant: take dopamine hydrochloride and NaH at a mass ratio of 5:1:1.2 2 PO 4 、Na 2 HPO 4 Mix to get the adjuvant.

[0061] Nano-hydroxyapatite solution: mix nano-hydroxyapatite, sodium citrate solution with a concentration of 1mol / L, and sodium bicarbonate at a mass ratio of 1:20:0.3 to obtain nano-hydroxyapatite solution.

[0062] Pretreatment of carp skin liquid: take carp skin, wash it with water 4 times the weight of carp skin, and dry it naturally to obtain a dry product. Take the...

Abstract

The invention belongs to the field of cosmetics, and particularly relates to a method for preparing a fiber nonwoven fabric for facial masks. The method adopts natural silk as a raw material, and obtains preprocessed silk fibroin liquid through degumming and dialysis; the natural Genipin with non-toxic side effects and CaCl2 are used as a crosslinking agent, so that the tensile strength and the breaking strain are improved. Some of the fat-soluble components of the skin can be dissolved, and the absorption of other effective nutrients can be improved. The method utilizes elastase and pepsin tocarry out secondary enzymatic hydrolysis of the preprocessed squid skin liquid, increases the number of free amino groups therein, and allows the protein in the squid skin liquid and the saccharide substances in the system to form a stable crosslinked network system. The method can effectively reduce the problem that the mechanical properties are degraded due to water absorption and swelling whenthe non-woven fabric acts on the mask nutrient solution, and the interaction of the components can avoid the problem of unintentional tearing. The method solves the problem that the fiber nonwoven fabric for facial masks which is commonly used at present is easy to be torn in use.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a preparation method of a fiber nonwoven fabric for facial masks. Background technique [0002] Mask is a beauty and skin care product for cleaning, caring and nourishing facial skin. The principle of the facial mask is to apply a thick layer of dressings with different functions and ingredients on the face to block the contact between the skin and the air. When this layer of dressing is tightly attached to the skin, it will increase the temperature of the skin by inhibiting the secretion of sebum and the evaporation of sweat; after the temperature of the skin rises, blood circulation will be promoted, and the nutrients that penetrate into the skin will be deeper between the cells. spread out more widely. The water that cannot evaporate on the surface of the skin will remain in the epidermis. When the moisture in the epidermis becomes full, the skin will look smoother and t...
