preparation example Construction

[0028] A preparation method of nutritional keratin facial mask, is characterized in that, comprises the steps:

[0029] S1: A certain amount of regenerated human hair keratin is completely dissolved in 98% (v / v) formic acid solution, and stirred evenly to obtain a spinning solution;

[0030] S2: Electrospinning is carried out by using a spinning solution to obtain a keratin nanofiber film;

[0031] S3: washing the keratin nanofiber membrane with a commercially available phosphate buffer solution to a pH value of 7.4, drying it and then activating it with a plasma processor;

[0032] S4: Soak the nanofibrous membrane obtained in step 3 in phosphate buffer solution added with skin nutrient factors for negative pressure flash explosion, and then perform grafting reaction;

[0033] S5: Centrifuge and freeze-dry the nanofibrous membrane that has completed the grafting reaction to obtain a nutritional keratin mask.

[0034] In the above-mentioned preparation method of the present ...

Embodiment 1

[0041] 1. Completely dissolve 2 g of regenerated human hair keratin in 100 ml of 98% (v / v) formic acid solution, stir evenly to obtain spinning solution;

[0042] 2. Electrospinning is carried out with the spinning solution, the syringe used is 10ml, the needle is flat, No. 7 needle; the electrospinning conditions are: voltage 15KV, distance 8cm, injection rate 0.5ml / h, temperature 30°C obtaining a keratin nanofiber film;

Abstract

The invention discloses a preparation method of nutritious keratin mask. The preparation method of the nutritious keratin mask comprises the following steps: (1) completely dissolving a certain amountof regenerated human hair keratin in a formic acid solution of which the concentration is 98%, and carrying out uniform stirring so as to obtain a spinning solution; (2) carrying out electro-spinningby utilizing the spinning solution so as to obtain a keratin nanofibre membrane; (3) performing rinsing-washing on the keratin nanofibre membrane by using a marketed phosphate buffer solution until the pH value reaches 7.4, carrying out drying, and carrying out activation treatment by using a plasma processor so as to obtain an activated nanofibre membrane; and (4) soaking the activated nanofibremembrane in a phosphate buffer solution containing skin nutrition factors so as to be subjected to negative-pressure flash blasting, carrying out grafting reaction, and carrying out centrifuging andlyophilizing. The nutritious keratin mask provided by the invention can be repeatedly used for 3-5 times, so that, the nutritious keratin mask has the advantages of being capable of protecting environment and saving resources; moreover, the nutritious keratin mask is safe to use, as well as significant in the functions of repairing epidermis, awakening skin, resisting aging, beautifying skin and nourishing.

Description

technical field [0001] The invention relates to the fields of cosmetics and biomedical engineering, in particular to a preparation method of a nutritional keratin facial mask. Background technique [0002] With the development of the global economy and the improvement of people's living standards and overall quality, more and more people start to use cosmetics, especially for daily care of facial skin, and with the development of society, people have more and more requirements for cosmetics. High, people prefer to use cosmetics with better actives and no preservatives. In the existing cosmetics, except the cream cosmetics used daily, facial masks are also a necessary product for daily facial skin care. There are mainly four types of facial masks: mud cream type, tear-off type, jelly type, and wet tissue type. The wet tissue type is generally a mask paper soaked in essence in a single package. According to the material, it is divided into: non-woven fabric, silk, cotton, po...
