Embodiment 1
[0019] A medical dressing for skin barrier protection containing ceramide: comprising the following raw materials in parts by weight: 1 part of ceramide, 1 part of compound sodium hyaluronate, 1 part of glycerin, 0.3 part of phenoxyethanol, 0.1 part of xanthan gum, and triethanolamine 1 part, 2 parts of laurocapram, 0.5 part of okra essential oil, 2 parts of brassicasterol, 1 part of p-anisic acid and the rest of water; The molecular weight of low-molecular sodium hyaluronate is 50kDa, and the molecular weight of oligomeric sodium hyaluronate is less than 50kDa. After the okra essential oil is washed with fresh okra water, it is refined by adding 3 times the weight of ethanol, and passed through a 100-mesh sieve to remove the coarse fiber residue. Low-temperature extraction was carried out at 30°C for 60 hours to obtain okra essential oil.
Embodiment 2
[0021] A medical dressing for skin barrier protection containing ceramide: comprising the following raw materials in parts by weight: 6 parts of ceramide, 5 parts of compound sodium hyaluronate, 3 parts of glycerin, 2 parts of phenoxyethanol, 0.9 part of xanthan gum, triethanolamine 3 parts, 6 parts of laurocapram, 2 parts of okra essential oil, 4 parts of brassicasterol, 5 parts of p-anisic acid and the remaining water; The molecular weight of low-molecular sodium hyaluronate is 1000kDa, and the molecular weight of oligomeric sodium hyaluronate is less than 50kDa. After the okra essential oil is washed with fresh okra water, 8 times the weight of ethanol is added to refine the pulp, and the coarse fiber slag is removed through a 150-mesh sieve. Low-temperature extraction was carried out at 44°C for 150 hours to obtain okra essential oil.
Embodiment 3
[0023] A medical dressing for skin barrier protection containing ceramide: including the following raw materials in parts by weight: 3 parts of ceramide, 3 parts of compounded sodium hyaluronate, 2 parts of glycerin, 1.5 parts of phenoxyethanol, 0.5 part of xanthan gum, and triethanolamine 2 parts, 4 parts of laurocapram, 1.3 parts of okra essential oil, 3 parts of brassicasterol, 3 parts of p-anisic acid and the remaining water; The molecular weight of low-molecular sodium hyaluronate is 800kDa, and the molecular weight of oligomeric sodium hyaluronate is less than 50kDa. After the okra essential oil is washed with fresh okra water, 5 times the weight of ethanol is added to refine the pulp, and the coarse fiber slag is removed through a 120-mesh sieve. Low-temperature extraction was carried out at 40°C for 100 hours to obtain okra essential oil.
