Embodiment 1
[0029] A preparation for protecting the activity of superoxide dismutase, comprising the following raw materials in parts by weight, SOD 300ml, sodium hyaluronate 1g, carbomer 2g, glycerol 100g, triethanolamine 10g, imidazolidinyl urea 1g, trehalose 5g, 122g of deionized water.
[0030] The preparation method of the preparation for protecting the activity of superoxide dismutase comprises the following steps:
[0031] (1) Carbomer is soaked in water for 1 day, and the weight ratio of the weight of the carbomer to water is 1:20. After soaking, trehalose and glycerol are added successively to the soaking liquid and stirred evenly. Then use the moist heat sterilization method to sterilize, the temperature during sterilization is controlled at 115°C, and sterilize at this temperature for 25 minutes to obtain the base liquid;
[0032] (2) Sodium hyaluronate is added in the SOD, and stir evenly, then filter and sterilize the SOD added with sodium hyaluronate with a bacteria filter ...
Embodiment 2
[0035] A preparation for protecting superoxide dismutase activity, comprising the following raw materials in parts by weight, SOD400ml, sodium hyaluronate 3g, carbomer 4.5g, glycerol 200g, triethanolamine 25g, imidazolidinyl urea 2g, seaweed Sugar 10g, deionized water 355.5g.
[0036] The preparation method of the preparation for protecting the activity of superoxide dismutase comprises the following steps:
[0037] (1) Carbomer is soaked in water for 3 days, and the weight ratio of the weight of the carbomer to water is 1:30. After soaking, trehalose and glycerol are added successively to the soaking liquid and stirred evenly. Then use the moist heat sterilization method to sterilize, the temperature during sterilization is controlled at 120°C, and sterilize at this temperature for 28 minutes to obtain the base liquid;
[0038] (2) sodium hyaluronate is added in SOD, and stir evenly, then carry out filter sterilization to the SOD that adds sodium hyaluronate with bacteria fi...
Embodiment 3
[0041] A preparation for protecting the activity of superoxide dismutase, comprising the following raw materials in parts by weight, SOD 500ml, sodium hyaluronate 4g, carbomer 6g, glycerol 300g, triethanolamine 50g, imidazolidinyl urea 3g, trehalose 15g, 581g of deionized water.
[0042] The preparation method of the preparation for protecting the activity of superoxide dismutase comprises the following steps:
[0043] (1) Soak the carbomer in water for 7 days, the weight ratio of the weight of the carbomer to water is 1:40, after soaking, add trehalose and glycerol successively to the soaking liquid and stir evenly, Then use the moist heat sterilization method to sterilize, the temperature during sterilization is controlled at 125°C, and sterilize at this temperature for 30 minutes to obtain the base liquid;
[0044] (2) sodium hyaluronate is added in SOD, and stir evenly, then carry out filter sterilization to the SOD that adds sodium hyaluronate with bacteria filter to obt...
