What is Magnesium chloride FCC

Magnesium chloride hexahydrate FCC is a high purity, naturally occuring salt with the formula MgCl2 6(H2O) which is suitable for ingestion. It is identified as E511 in the food industry. It is mostly produced from sea water and in particular the Dead Sea. Magnesium chloride as the natural mineral bischofite is also extracted (solution mining) out of ancient seabeds, for example the zechstein seabed in NW europe.
It is a colourless to white, odourless salt with a bitter taste. It has been used for centuries as an aid to improving health and well being. Its therapeutic properties are well recognised and people flock to the Dead Sea every year to bathe in its water to rejuvenate themselves. It is used in the pharmaceutical industry, pharmaceuticals, dialysis and infusion solutions, children and infantile diets, food complements, drinks, salts for sea aquariums.

Magnesium chloride BP in the food industry

Magnesium chloride is E511. It is an ingredient in infant formulas. It is used as acidity regulator. It is added to purified water to produced mineral water. E511 is an important coagulant used in the preparation of tofa from soya milk. It is used both as a colour retention agent and firming agent in canned peas. It acts as a stabilizer in foods.

Magnesium Chloride BP for health benefits

For many years Magnesium chloride has been used for batheing and ingesting to improve health and well being. For an insight into the many health benefits of the “Miracle mineral” click here

Magnesium is an essential mineral for the body. Magnesium is a required cofactor for many enzyme systems. It is required for protein synthesis and for both anaerobic and aerobic energy generation and for glycolysis, either indirectly as a part of magnesium-ATP complex or directly as an enzyme activator (Bronzetti et al., 1995; Food and Nutrition Board, 1997).
Magnesium plays a multifunctional role in cell metabolism, particularly at the level of key phosphorylations. The role of magnesium in cell division is also well recognised and it has been suggested that cell division of various cell types is highly dependent on the availability of extracellular magnesium (Rubin, 1975).
In addition magnesium may play an important role in regulating blood pressure, bone and muscle growth and helps to reduce the development of atherosclerosis, cardiac arrhythmias, myocardial damage and arterial hypertension.
Magnesium deficiency has been linked to several disease states involving the cardiovascular, skeletal, gastrointestinal and central nervous systems. The most frequent causes of hypomagnesemia are reduced intake, impaired intestinal absorption, renal loss and genetic diseases.

Magnesium chloride BP in Medical industry

Magnesium chloride is an electrolyte replenisher and a pharmaceutical necessity for hemodialysis and peritoneal dialysis fluids. It is used as a source of magnesium in the treatment of hypomagnesemia in cattle, and as a chemical defibrillator in cardiopulmonary resuscitation.
Magnesium chloride acts as a laxative, an antacid and a anticonvulsant. It increases osmotic gradient in small intestine, which draws water into intestines and causes distention. These effects stimulate peristalsis and bowel evacuation. In antacid action, it reacts with hydrochloric acid in stomach to form water and increase gastric pH. In anticonvulsant action, magnesium chloride depresses CNS and blocks transmission of peripheral neuromuscular impulses.


Magnesium chloride hexahydrate is for adding magnesium to sea water. Severely low values of magnesium (900 mg/L or below) can cause low pH values and an inability to maintain proper alkalinity and calcium values. If magnesium becomes too low, coral growth will stop and followed by a decline in coral health. Carbonates and calcium are essential for all growth of corals, coralline algae, clams and invertebrates. Maintaining the correct magnesium values is very important and is indirectly responsible for coral and coralline algae growth by making it possible to maintain correct calcium, alkalinity and pH values. The magnesium content must often be increased, as shortfalls in the content can arise for various reasons. The normal magnesium content is around 1.30 ??? 1.40 mg/litre (1300???1400 ppm). To increase the magnesium content you need magnesium chloride hexahydrate or a mixture of magnesium chloride and magnesium sulphate (ratio of 7:1).

How to dose aquarium with magnesium chloride

50g will raise Magnesium levels by approximately 60ppm in 100 litres of salt water. It is not recommended to increase Magnesium levels by more than 60ppm per day. Simply mix the required amount into a few litres of Reverse Osmosis Water, once dissolved, slowly add to your tank in an area of high flow, preferably over a period of an hour. Alternatively add to your evaporation top up water and top up as normal.

Health & safety

Not a hazardous substance or mixture according to Regulation (EC) No. 1272/2008.
