About:

Functions:
1. Acidity Regulator / Buffering Agent - Changes or maintains the acidity or basicity of food/cosmetics.
2. Anti-caking Agent - Prevents lumps from forming in food due to excess water. They usually function as a water repellent or by absorbing excess moisture.
3. Colorant - Pigments or dyes that are added in order to change or enhance the color.
The primary use of magnesium carbonate is the production of magnesium oxide by calcining. Magnesite and dolomite minerals are used in flooring, fireproofing, fire extinguishing compositions, cosmetics, dusting powder, and toothpaste. Other applications are as filler material, smoke suppressant in plastics, a reinforcing agent in neoprene rubber, a drying agent, a laxative to loosen the bowels, and color retention in foods. In addition, high purity magnesium carbonate is used as an antacid and as an additive in table salt to keep it free-flowing. [1]
As a food additive magnesium carbonate is known as E504, for which the only known side effect is that it may work as a laxative in high concentrations.
It is approved to use as food additive in EU and generally recognized as safe food substance in US.
