The invention provides a
collagen gel and a preparation method thereof. The
collagen gel comprises collagen and an
antibacterial agent, wherein the
antibacterial agent is at least one of
chitosan and nano silver. The
collagen gel also comprises a
preservative, a substrate, a dispersing agent, a film-forming agent and water; and 1g of gel comprises 0.5 to 8.0mg of collagen, 0.001 to 15mg of
antibacterial agent, 1 to 50mg of
preservative, 10 to 50mg of matrix, 50 to 100mg of dispersing agent, 1 to 10mg of film-forming agent, and the balance of water. The method for preparing the collagen gel comprises the following steps of: performing dispersion and
dissolution on the substrate by adopting the dispersing agent under ten-thousand grade
clean environment; adding the dispersing agent, the substrate, the
preservative, the antibacterial agent, and collagen solution into a vacuum emulsified
homogenizer one by one; after fully mixing, standing and defoaming, filling the product. The collagen gel is applied to various
open wounds and infected wounds, lightens
hyperpigmentation, has good effect of accelerating
wound healing, and can maintain long-term anti-
bacteria function.
