Global Magnesium Hydroxide Market: Overview

Magnesium hydroxide is a popular and versatile inorganic compound as it does not contain carbon-hydrogen bonds. The chemical formula for the compound is Mg(OH)2. In nature, magnesium hydroxide is available as the mineral brucite which is a low-temperature hydrothermal vein mineral. Mg(OH)2 appears as a white solid and exhibits low water solubility. It has wide applications in end-user verticals including the healthcare and food industries. In the medicine industry, it is profoundly popular as an antacid and an active key ingredient for extensively consumed laxatives such as milk of magnesia.

Apart from these most common applications, the market is filled with several research initiatives working toward improving compound use which could lead to further growth for the market players. However, in recent times, the magnesium hydroxide market growth trend has registered specific setbacks associated with health concerns over excessive consumption of magnesium hydroxide. Nevertheless, the Mg(OH)2 outlook is projected to be steady during the forecast period as more investments pour in toward the increased production rate of the compound.

Global Magnesium Hydroxide Market: Growth Drivers

Promising application as a laxative and an antacid to drive market growth

The global magnesium hydroxide market is projected to grow owing to the promising application of the compound as a popular laxative and an antacid. It is used for treating occasional constipation in children and adults on a short-term basis and belongs to the saline laxatives class of medications. It helps in water retention in the stool resulting in an increased number of bowel movements. Magnesium hydroxide is typically available in tablet or chewable tablet form but can also be found in liquid form to be taken by mouth. It is known to cause bowel movement within 30 minutes of intake but may take over 6 hours in some cases.

The extended medical applications of magnesium hydroxide include its use as an antacid since it is known to treat conditions such as heartburn, upset stomach, and acid indigestion. Depending on the doctor's recommendation, it can be prescribed for other conditions as well. The increasing population rate and surging number of adults or children facing constipation are excellent market growth drivers. Several factors are responsible for improper bowel movement in adults including limited consumption of fiber, changes in routine or lifestyle, and not paying enough attention to the need for passing stool. As per a report by the National Institutes of Health (NIH), around 16 in every 100 people in the US exhibit constipation symptoms regularly.

Increasing construction of new Mg(OH)2 production facilities may push market growth rate

The industry for magnesium hydroxide is projected to gain higher momentum in terms of revenue due to the rising compound production rate globally and also includes strategic partnerships, acquisitions, or joint ventures. In a recent market move, RHI Magnesita (RHIM), a leading supplier of refractory products, sold its 50% stakes in Magnifin Magnesiaprodukte GmbH & Co. KG, one of Australia’s largest producers of magnesium hydroxide to J.M. Huber Corp., America's prominent corporation. The overall transaction was valued at USD 100 million and has strengthened J.M. Huber Corp’s footprint in the chemical industry

Restraints:

Health concerns over excess consumption of magnesium hydroxide may restrict market growth

The global magnesium hydroxide market growth is projected to be limited due to certain health concerns associated with the excess or unwanted consumption of magnesium hydroxide. Medical professionals recommend against magnesium hydroxide unless necessary and when prescribed, it should be consumed in advised doses. Excess amounts of magnesium hydroxide medicine can lead to severe diarrhea. Another key unwanted impact deals with high magnesium levels leading to shallow breathing, muscle weakness, mood changes, and irregular heartbeat. Patients have also complained of dehydration symptoms, rectal bleeding, abdominal pain, and bloody stools. While a serious allergic reaction to the drug is rare, significant risk still persists. These factors do not work in the favor of magnesium hydroxide medicine especially when consumed in quantities more than required.

Opportunities:

Growing applications in flue gas desulfurization (FGD) will open new avenues for expansion

During the projection period, the demand for magnesium hydroxide is projected to grow multifold as higher applications of the compound are emerging in the FDH market segment. Flue gas desulfurization deals with the use of multiple technologies and methods for the removal of toxic sulfur content such as sulfur dioxide (SO2) from exhaust flue gasses produced by power plants running on fossil fuel. It is also used for the removal of sulfur oxide-emitting processes such as petroleum refineries, incineration plants, and lime kilns. Sulfur dioxide is an extremely harmful environmental pollutant and can lead to several serious health risks including bronchitis and asthma attacks.

It has also been linked to various cardiovascular diseases (CVDs). The environmental impact of SO2 is more severe as it is directly related to the formation of acid rain that causes deforestation and hampers marine ecosystems. These events have led to governments and international environment bodies regulating the release of SO2 in the environment. For instance, as per regulations in the US, the hourly average for sulfur dioxide is 75 parts per billion. Magnesium hydroxide is used in the desulfurization process as it follows 3 simple steps to achieve the goal including absorption, oxidation, and separation.

Use of magnesia power requires more attention

Magnesia powder is used as fillings for electrical materials and this segment requires more attention from the players as it holds tremendous growth potential. Fused magnesia possesses excellent electric and thermal resistance which means it can be used to form a protective layer between the outer sheath and the element. In cable applications, it is used as mineral insulation.

Challenges:

Availability of substitutes across end-uses to challenge market growth

The magnesium hydroxide industry expansion trajectory will be challenged by the presence of an extensive market filled with alternatives to magnesium hydroxide across end-user verticals. For instance, some other popular antacids available in the market are sodium bicarbonate, calcium carbonate, proton pump inhibitors, simethicone, and others. Some of these variants are safer than magnesium hydroxide. Similarly, other substitutes for FGD are also highly prevalent leading to serious market fragmentation.
