In medicine, the hydrophilicity of fumed silica can be used to eliminate edema and reduce the secretions produced by wound inflammation; help diarrhea patients fix and bind water; widely used as a desiccant in dermatology, and its high adsorption can be used Absorb microorganisms and microviruses
.
Fumed silica can also be used as a stabilizer and drug carrier for emulsions, prolonging the efficacy and promoting drug absorption
.
? Hydrophilic fumed silica is a key excipient in a variety of pharmaceutical and nutritional additive products; it can act as a glidant or free-flowing additive, thereby providing higher tablet production efficiency and better tablets The uniformity and strength of the agent; improve the free flow of powder and granules, and help the filling of the capsule
.
For soft gel capsules, fumed silica can provide anti-settling properties of insoluble components in the liquid or gel before or during the filling of the soft gel capsule
.
The thickening mechanism of fumed silica is not highly dependent on temperature, so it can be used to form non-melting gels and semi-solids, such as suppositories
.
? Fumed silica used in ointment can absorb liquid active ingredients, and can release active ingredients on the skin well.
The paste is uniform and has no component separation phenomenon, so that it becomes liquid when applied, and in a wide range Stable in the temperature range
.
In the use of tablet medicine, it improves the flow of materials, and the tablet is easy to take out from the mold.
Even if it is stored under high relative humidity, it will not cause problems, and it has a strong dissolving ability
.
? In drugs containing griseofulvin and other drugs, adding a small amount of fumed silica can change the dissolution rate, that is, changing the dispersibility and absorption of the dissolved drug in water; in powders containing aspirin, adding a small amount of fumed silica, It will change the antistatic property of the drug; use fumed silica surface to coat appropriate monolayer material, and then disperse it in a colloidal solution of polyvinylpyrrolidone containing a variety of cells.
Through centrifugal technology, the required cells can be quickly recovered.
Separate out, and will not stain the cells
