Magnesium Trisilicate (CAS 14987-04-3), min. 20% MgO and 45% SiO2, pharmaceutical and food grade, supplied wholesale by Zyntex. Antacid API, food anticaking agent and adsorbent. CoA and SDS with every lot.
Magnesium trisilicate is a fine white powder with at least 20% MgO and 45% SiO2. It is practically insoluble in water and reacts slowly with acid, which gives a gentle and prolonged neutralizing effect.
In addition, pharmaceutical companies use it in antacid tablets and oral suspensions, usually together with Aluminum Hydroxide and Magnesium Hydroxide. Similarly, food producers use magnesium silicates as anticaking agents (E553a) within the limits set by regulations, and industrial users use it as an adsorbent and filtration aid, for example in purifying frying oils.
Furthermore, other antacid and magnesium ingredients in our range include Magaldrate and Magnesium oxide.

💊 Antacids
API for tablets as well as suspensions.

Why is magnesium trisilicate combined with aluminium hydroxide?
Because the two act at different speeds and balance each other’s side effects, the combination gives steady acid neutralization.
Which grades do you supply?
Pharmaceutical as well as food grades are available.
