Embodiment 1
[0023] A method for preparing a liquid wound dressing that promotes rapid repair of skin damage, and its steps are as follows:
[0024] 1. Preparation of solution A: add 70-80% of the total prepared water in the preparation tank, and slowly add 10% of the total prepared solution of polyglutamic acid, 18% of gum arabic, and 0.02% of the total Ethyl p-hydroxybenzoate and propyl p-hydroxybenzoate are stirred for 10-20 minutes to obtain solution A;
[0025] 2. Preparation of solution B: add 15% glycerin to solution A, stir for 10~15min, control pH at 5~6.5, add 1% keratin, 1% ferulic acid and 5% of the total prepared solution Thirteen peptides, heated to 40~50℃, stirred for 15~20min to obtain solution B;
[0026] 3. Preparation of solution C: add solution B to the high-pressure homogenizer, add water to the total amount of the solution, maintain the temperature at 40~50℃, homogenize at high speed for 5~7min until the whole system has no particulate solids, and cool to room temperature t...

[0029] A method for preparing a liquid wound dressing that promotes rapid repair of skin damage, and its steps are as follows:
[0030] 1. Preparation of solution A: add 70-80% of the total prepared water in the preparation tank, and slowly add 15% polyglutamic acid, 13% gum arabic, and 0.02% of the total prepared solution in sequence. Ethyl p-hydroxybenzoate and propyl p-hydroxybenzoate are stirred for 10-20 minutes to obtain solution A;
[0031] 2. Preparation of solution B: add 10% glycerin to solution A, stir for 10~15min, control the pH at 5~6.5, add 1% keratin, 1.5% ferulic acid and 4.5% of the total prepared solution Thirteen peptides, heated to 40~50℃, stirred for 15~20min to obtain solution B;
[0032] 3. Preparation of solution C: add solution B to the high-pressure homogenizer, add water to the total amount of the solution, maintain the temperature at 40~50℃, homogenize at high speed for 5~7min until the whole system has no particulate solids, and cool to room temperature...
