high quality Magnesium hydroxide CAS 1309-42-8
Products Description
Magnesium dihydroxide is a magnesium hydroxide in which the magnesium atom is bound to two hydroxide groups. It has a role as an antacid and a flame retardant.
Magnesium hydroxide is an inorganic compound. It is naturally found as the mineral brucite. Magnesium hydroxide can be used as an antacid or a laxative in either an oral liquid suspension or chewable tablet form. Additionally, magnesium hydroxide has smoke suppressing and flame retardant properties and is thus used commercially as a fire retardant. It can also be used topically as a deodorant or for the relief of canker sores (aphthous ulcers).
Magnesium Hydroxide is a solution of magnesium hydroxide with antacid and laxative properties. Milk of magnesium exerts its antacid activity in low doses such that all hydroxide ions that enter the stomach are used to neutralize stomach acid. This agent exerts its laxative effect in higher doses so that hydroxide ions are able to move from the stomach to the intestines where they attract and retain water, thereby increasing intestinal movement (peristalsis) and inducing the urge to defecate.

Benefits
- Antacid: Magnesium hydroxide is commonly used as an antacid to relieve symptoms of heartburn, indigestion, and upset stomach. It works by neutralizing excess stomach acid.
- Laxative: It can also be used as a laxative to treat constipation. It draws water into the intestines, which helps to soften stool and promote bowel movements.
- pH Regulation: In industrial applications, magnesium hydroxide is used to neutralize acidic waste streams and to adjust the pH of various solutions.
- Flame Retardant: Due to its thermal stability, magnesium hydroxide is used as a flame retardant in plastics, rubber, and other materials.
- Water Treatment: It is used in water treatment processes to remove impurities and to neutralize acidic water.
Application
- Pharmaceuticals: Magnesium hydroxide is found in over-the-counter medications for heartburn and constipation, often marketed as “milk of magnesia.”
- Cosmetics: It can be used in cosmetic formulations as a thickening agent and to help stabilize emulsions.
- Food Industry: In some cases, magnesium hydroxide is used as a food additive (E528) to regulate acidity.
- Agriculture: It can be used to improve soil pH and as a magnesium supplement for plants.
- Industrial Uses: It is employed in the production of magnesium oxide, as a filler in various products, and in the manufacture of refractory materials.
