Embodiment 1
[0024] Embodiment 1: the preparation step of 4% pyridoxazole+0.2% osthole suspoemulsion
[0025] The preparation of A, 8% pyridoxazole aqueous emulsion
[0026] Weigh 80g of pyridoxazole, 100g of xylene, 30g of emulsifier (By140), 2g of thickener xanthan gum, 20g of antifreeze ethylene glycol, 2g of defoamer, and make up to 1kg with deionized water. Dissolve pyridoxazole in xylene as a cosolvent, mix with emulsifier (BY140) and stir evenly, then slowly pour the above liquid into water, add thickener xanthan gum, antifreeze ethylene glycol and disinfectant The foaming agent is prepared after high-speed shearing.
[0027] B, the preparation of 0.4% osthole suspension
[0028] Weigh 4g of osthole, 30g of dispersant (D-425), 2g of thickener xanthan gum, 20g of antifreeze ethylene glycol, 2g of defoamer, and make up to 1kg with water. Mix the original drug of osthole with dispersant (D-425), antifreeze ethylene glycol, and water, mix them fully, put them into a sand mill and gri...
