Magnesium aluminum silicate (neusilin, magnesium aluminometasilicate), actually literally translated as magnesium aluminum metasilicate, is a substance with a very large specific surface area and a well-developed microporous system. It can be used as an adsorbent and absorbent (which can absorb three times Quality liquid), moisture-proof agent, etc. But it is insoluble in water and alcohol.
It has the following characteristics:
1. It is a fine powder of amorphous aluminum magnesium silicate.
2. It has a huge special surface area, strong oil absorption and adsorption capacity, and excellent dispersion ability.
3. Excellent compressibility.
4. It does not deteriorate for a long time and has heat resistance.
5. There are many types of magnesium aluminum silicate. The classification is based on the apparently different adsorption capacity of magnesium aluminum silicate, water content, and the ph value of particles (4 content slurry). Can be selected according to various specific needs.
Magnesium aluminum silicate has been used for many years in the formulation of tablets, ointments, and creams. It is used in oral and topical formulations as a suspending and stabilizing agent either alone or in combination with other suspending agents.The viscosity of aqueous dispersions may be greatly increased by combination with other suspending agents, such as xanthan gum, owing to synergistic effects.In tablets, magnesium aluminum silicate is used as a binder and disintegrant in conventional or slow-release formulations.
Magnesium aluminum silicate may cause bioavailability problems with certain drugs
