Embodiment 1
[0026] This example is a specific example of extracting rat tail collagen from rats.
[0027] The extraction method of rat tail collagen comprises the following steps:
[0028] (1) SPF grade rats were taken, and after euthanasia, the tails were cut off immediately, placed on ice, peeled off the skin, flattened, bones and muscles removed, and placed in 0.01 to 0.2 mol / L Tris~HCl buffered saline solution, the extracted tail collagen is white filamentous.
[0029] (2) The above-mentioned filaments are pretreated at 0-10° C. for 4-36 hours, stirred to remove impurities, filtered to dry water, and added with 0.05-2 mol / L acetic acid solution. Add pepsin at a ratio of 1; 1000 to 1; 50000, add in three times, and finish adding in 12 to 36 hours. During this period, stir continuously until all the tail tendons are enzymatically hydrolyzed and present as latex. Enzymolysis lasts for 36-144 hours.
[0030] (3) Centrifuge the latex-like solution at 0-10°C for 10-40 minutes to remove...

[0036] This example is a specific example of extracting rat tail collagen from mice.
[0037] The extraction method of rat tail collagen comprises the following steps:
[0038] (1) Take SPF mice, and after euthanasia, immediately cut off the tail, put it on ice, peel off the skin, flatten it, remove the bone and muscle, and place it in a 0.01-0.2mol / L Tris~HCl buffered saline solution, the extracted tail collagen is white filamentous.
[0039] (2) The above-mentioned filaments are pretreated at 0-10° C. for 4-36 hours, stirred to remove impurities, filtered to dry water, and added with 0.05-2 mol / L acetic acid solution. Add pepsin at a ratio of 1; 1000 to 1; 50000, add in three times, and finish adding in 12 to 36 hours. During this period, stir continuously until all the tail tendons are enzymatically hydrolyzed and present as latex. Enzymolysis lasts for 36-144 hours.
[0040](3) Centrifuge the latex-like solution at 0-10°C for 10-40 minutes to remove solidified matter ...
Embodiment 3
[0046] This example is a specific example of using the rat tail collagen stock solution prepared in Example 1 to prepare a facial mask.
[0047] Table 1: Mask Prescription
[0048]
[0049] The preparation method is as follows:
[0050] (1) Add an appropriate amount of water to dissolve the rat tail collagen in phase A until completely dissolved, and set aside.
[0051] (2) Dissolve sodium hyaluronate, coenzyme Q10, serum albumin, and 1,3-butanediol in phase B in an appropriate amount of water, heat to dissolve completely, and wait for cooling before use.
[0052] (3) Add the product in step (1) dropwise to the solution of (2) under ice bath conditions, and stir for half an hour to make it fully combined.
[0053] (4) Add castor oil and glycerin in phase C to an appropriate amount of water to dissolve.
[0054] (5) Keep the ice bath at a low temperature, drop the solution of (3) into (4), and stir rapidly to disperse.
[0055] (6) Add all the remaining amount of water i...
