Magnesium carbonate is a multifunctional new inorganic material, in recent years in catalysis, optics, magnetism, mechanics and so on show a lot of special functions, so that it has an important application value in ceramics, chemical industry, electronics, optics, biology, medicine, and many other fields, with ordinary magnesium carbonate can’t be compared to the special characteristics and uses.
Magnesium carbonate is a common additive used in many fields such as food, medicine, cosmetics and agriculture. The additive ratio varies according to the specific application, and the following lists the range of additive ratios for some common industries:
Food industry
Beverages (except for overpacked drinking water, fruit and vegetable juice, carbonated beverages): Nutritional fortifier, the amount added is 30-60mg/kg (in magnesium).
Gum-based confectionery: base agent substance in gum-based confectionery, used in appropriate amount according to production needs (except for those with special regulations).
Protein-based solid beverage (cocoa powder solid beverage): flour treatment agent, the amount added is 10.0g/kg.
Wheat flour: flour treatment agent, the amount added is 1.5g/kg.
Pharmaceutical industry
Light magnesium carbonate: commonly used as laxative, antacid, made into tablets, dispersions, emulsions and so on. The dosage depends on the specific dosage form and the patient’s age and physical condition.
Heavy magnesium carbonate: mainly used in industrial pharmaceuticals, the production of magnesium oxide, magnesium sulfate, magnesium chloride and other magnesium salts.
Cosmetic industry
Magnesium carbonate is often used as filler, adsorbent, thickener and so on. The amount added in cosmetics such as flour, talcum powder and eye shadow is generally 5%-20%.
Agricultural industry
Magnesium carbonate can be used as feed additives to supplement magnesium and promote the growth of livestock and poultry. The added amount is generally 0.1%-0.3%.
Other industries
Magnesium carbonate can also be used in rubber, plastics, paper, ceramics, paint and other industries, the specific additive ratio depends on the specific application.
It should be noted that the above additive ratio is for reference only, the actual application should strictly follow the national or industry standards.
