Pharmaceutical Grade Magnesium Aluminum Silicate (Veegum)

Pharmaceutical grade magnesium aluminum silicate (MAS) is mainly used as excipients in pharmaceutical industries. Due to it’s water absorption, suspension, dispersion, adhesion, thixotropy, magnesium aluminum silicate as preparation auxiliary has the function of emulsification, adsorption, excellent pharmaceutical excipients. Magnesium aluminum silicate are set out respectively in the United States Pharmacopoeia, European Pharmacopoeia, British Pharmacopoeia. It has also been included in the “new product development of a national pharmaceutical preparations Guide” in China.
