Embodiment 1

[0032] Embodiment 1: Preparation of keratin

[0033] Clean and crush the wool, pretreat it with a sodium thioglycolate solution with a pH value of 11 and a concentration of 0.5 mol / L (sodium hydroxide to adjust the pH) at normal pressure and room temperature (20°C to 30°C) for 3 hours, and then add to the solution Add urea in the solution, the amount of urea added is such that the concentration in the solution reaches 7mol / L, and then the reduction reaction is carried out at normal pressure and room temperature (20°C to 30°C) for 25 hours. After the reaction time expires, drop acetic acid to adjust the concentration of the reaction solution. When the pH value reaches 6-8, oxygen is introduced into the solution and reacted at room temperature (20°C-30°C) for 0.5 hours. After the reaction time expires, filter under normal pressure, and filter the filtrate with a dialysis bag with a relative molecular weight cut-off of 20-80kD. Dialysis and centrifugation to obtain the primary pr...

Embodiment 2

[0034] Embodiment 2: preparation collagen

[0035] Wash fresh pigskin (or fresh cowhide) to remove subcutaneous fat, depilate and chop, soak in 10% NaCl solution for 12 hours to remove salt-soluble impurities, after soaking time expires, wash with deionized water 2 to 3 times , and then add deionized water to beat and mix to obtain slurry. Add HAc and pepsin of concentration 0.5mol / L in above-mentioned slurry, the add-on of HAc is 5% of slurry volume, the add-on of pepsin is 5% of slurry weight, and the pH value of control slurry is at 2 ~3, and then enzyme treatment at normal pressure and room temperature for 72 hours. After the enzyme treatment time expires, centrifuge (3000r / min) to take the supernatant, add NaCl to the supernatant for collagen salting out, the NaCl concentration is 2mol / L, centrifuge (8000r / min), and the precipitation is collagen protein. Then re-dissolve the collagen in 0.5mol / L Hac, repeat the salting out twice with NaCl, then dissolve the collagen in...

Embodiment 3

[0037] Embodiment 3: the preparation of facial mask liquid

[0038] In the present embodiment, the component (raw material) and mass fraction thereof of mask liquid are as follows:

[0039] 0.5% protein composition: the protein composition is composed of keratin and collagen, and the mass ratio of keratin to collagen is 1:0.2;

[0040] Fat 3%: polyglyceryl-4 laurate 1%, citrate dilaurate 2%;

[0041] Emulsifier 1%: Glyceryl Stearate;

[0042] Humectant 4%: glycerin 3%, propylene glycol 1%;

[0043] Thickener 0.12%: Acrylates / C10-30 Alkyl Acrylate Crosspolymer;

[0044] Nutritional additives 0.5%: vitamin E acetate 0.4%, allantoin 0.1%;

[0045] Deionized water 90.88%.

[0046] The preparation method of facial mask liquid is as follows:

[0047] Put the raw materials polyglycerol-4 laurate, citrate dilaurate, acrylate / C10-30 alkyl acrylate crosslinked polymer, vitamin E acetate, allantoin into the oil phase pot, and stir in the Heating to 60°C under normal pressure, when...

The protein skin care product of the invention having the function of skin repair and care includes mask liquid, cream and cleansing emulsion.

Description

technical field [0001] The invention belongs to the field of skin care products, in particular to skin care products with skin repair and maintenance functions. Background technique [0002] The skin is the largest organ of the human body, with a total weight of 5% to 15% of the body weight and a total area of ​​1.5 to 2 square meters. The skin has two barrier functions: on the one hand, it prevents the loss of water, electrolytes and other substances in the body; on the other hand, it prevents the intrusion of harmful substances from the outside and maintains the stability of the internal environment of the human body, which plays an important protective function physiologically. As we grow older, the skin is exposed to ultraviolet rays and pollutants in the air, and it is prone to lack of nutrition, which will cause the skin to lose water, destroy the keratin of the skin, and cause the skin to become rough and lose its elasticity. In order to nourish the skin and prevent ...
