It is mainly used as auxiliary materials in the pharmaceutical industry. Because of its water absorption, suspension, dispersion, cohesiveness and thixotropy, it has the function of emulsification and adsorption as auxiliary materials of preparations, which is an excellent pharmaceutical auxiliary material. Magnesium aluminum silicate is collected in the United States Pharmacopoeia, the European Pharmacopoeia and the British Pharmacopoeia respectively. It is also included in the new products of pharmaceutical preparations in China Development guide.

1.Adsorbent:

It has lamellar striate structure and non-uniform electrical distribution, which has strong selective adsorption on some viruses, pathogens and toxins in the digestive tract.

2. Filter agent:

In pharmaceutical production, it can act as adsorbent and filter.

3. Emulsifier and ointment matrix:

It can be used as thickener of ointment and paste, or as emulsifier of ointment matrix and emulsion.

4. Adhesive:

It has some viscidity, which can be used in the field of dentistry. It can be made into dental cement powder to treat oral diseases.

5.Carrier:

It is a kind of mineral with nanometer structure. It can be used as catalyst carrier in chemical synthesis. It can also be used as carrier of pesticide (insecticide, bactericide) to make pesticide highly dispersed. It can be used as carrier of insect repellent in pharmaceutical field. When antiparasitic drug is added into magnesium aluminum silicate, it can be made into intestinal insect repellent.

6. Excipients:

It can be used as pharmaceutical auxiliary material, which has superior disintegration performance and has no effect on nervous system, respiratory system and cardiovascular system.

It is mainly used in suspension, pharmaceutical auxiliary materials (emulsifier and ointment matrix, filter agent, adhesive, adsorbent, excipient, disintegrating agent, controlled release agent, carrier), pesticide gastric lavage and antidote, etc.
