Embodiment 1
[0011] Example 1 Stomach-soluble iron red film coating premix
[0012] 1. Prescription composition:
[0013] Hydroxypropyl Methyl Cellulose 70%
[0014] Glyceryl Triacetate 4%
[0015] Tween-80 0.1%
[0016] Polyvinyl alcohol 1%
[0017] Talc 10.5%
[0018] Silica 0.1%
[0019] Titanium dioxide 6.8%
[0020] Yellow Iron Oxide 1.6%
[0021] High Concentration Carmine Aluminum Lake 5.9%
[0022] 2. Preparation method: Put the hydroxypropyl methylcellulose and polyvinyl alcohol in the stated ratio in a super mixer and mix at 50°C for 5 minutes at low speed, then add triacetin and Tween-80 and mix at high speed for 20 minutes , out of the material, to obtain a dispersion medium. Then add the dispersion medium, talcum powder, silicon dioxide, titanium dioxide, yellow iron oxide, and high-concentration carmine aluminum lake into the super mixer for high-speed dispersion for 30 minutes, and the finished product is obtained after the discharge is sieved.
