Market Drivers

Increase in Demand in the Industrial Manufacturing Sector Driving the Demand for Magnesium Hydroxide Market

Magnesium hydroxide is used extensively in industrial production plants for desulfurization and wastewater treatment. Magnesium hydroxide is largely used as an antacid in the pharmaceutical business. Magnesium hydroxide's inherent flame-retardant properties make it an essential ingredient in rubber, plastics, and construction materials. The increasing focus on fire safety, especially in residential and commercial buildings, is propelling market expansion. In the chemical industry, magnesium hydroxide is used in many different chemical processes because it neutralizes acidic substances. The expansion of the chemical industry is directly related to the demand for magnesium hydroxide. Due to new applications in food additives, medications, and personal care products, the industry is expanding overall.

Market Trend

Growing Demand from the Wastewater Treatment Sector to Boost the Demand in the Forecast Period

Magnesium hydroxide has multiple applications in wastewater treatment processes. By raising the pH of acidic water, magnesium hydroxide reduces corrosion. It makes it more appropriate for a range of industrial applications, including cooling towers, furnaces, and municipal water supply systems. Magnesium hydroxide can be used as a coagulant or flocculant in wastewater treatment. It increases the ability of suspended particles to separate from the water by making it simpler for them to deposit and agglomerate. This is particularly useful when cleaning water particles and turbidity. The world's population is also growing quickly, and growing industry and urbanization are having a major negative impact on freshwater supplies. Industrial operations use twenty-two percent of the water used globally.

COVID Impact on Magnesium Hydroxide Market

Due to the strict regulations and lockdown resulting from the COVID-19 pandemic, the demand for magnesium hydroxide has decreased, which has negatively impacted the global market for this product. The manufacture of magnesium hydroxide is also disrupted by social alienation and workforce scarcity. In 2020, however, governments worldwide enforced strict precautions to prevent the spread of the COVID-19 pandemic. Among other things, these actions included halting output and limiting construction. The supply chain was restored in 2021 as a result of the rule-easing, which encouraged the growth of the magnesium hydroxide sector. The food industry is driving the increasing demand for magnesium hydroxide.

Competitive Landscape

A variety of companies are vying for market dominance in the magnesium hydroxide industry through strong marketing campaigns, strategic alliances, and new product development. Established electronics manufacturers, specialized magnesium hydroxide companies, and up-and-coming start-ups hoping to upend the market with creative solutions are some of the major participants in the market.

Segment Analysis

Magnesium Hydroxide Market, By Form

The liquid segment is expected to dominate the magnesium hydroxide market. Because it is easy to apply and absorbed rapidly, liquid magnesium hydroxide is used to treat the symptoms of endometriosis. The growing demand for natural products by consumers has led to a preference for liquid magnesium hydroxide over synthetic alternatives.

However, the powder segment is expected to grow at the fastest CAGR during the forecast period. Magnesium hydroxide is widely used in many industries, such as chemicals, food processing, flame retardants, wastewater treatment, and pharmaceuticals. Its adaptability and effectiveness across these many industries are partially responsible for its market dominance. Because of its fundamental properties and applications, magnesium hydroxide powder is widely recognized in the industry. Since it is utilized in wastewater treatment to regulate pH levels and get rid of odours, it is crucial to maintain the quality of the water.

Magnesium Hydroxide Market, By Grade

The technical/industrial segment is expected to dominate the magnesium hydroxide market. Because of its special properties and low cost, this grade of magnesium hydroxide is most frequently used in industrial settings. Brine evaporation, seawater electrolysis, and dolomite calcination are some of the methods used to make it. The usage of magnesium hydroxide as an absorbent in flue gas desulfurization, acid neutralizers, and wastewater treatment applications is increasing.

However, the pharma segment is expected to grow at the fastest CAGR during the forecast period. Magnesium hydroxide is primarily used as an antacid and laxative. It alleviates indigestion and heartburn due to its slightly alkaline properties, which regulate stomach acid. By drawing water to the intestines, it acts as a laxative, softening stool and encouraging bowel movements.

Magnesium Hydroxide Market, By Applications

The wastewater treatment segment is expected to dominate the magnesium hydroxide market. Magnesium hydroxide is a key component in water quality management and is widely used in wastewater treatment because of its ability to eliminate odours and regulate pH levels. It is used in both aerobic and anaerobic biological treatment systems in a variety of industries, including bakeries, chemical processing plants, and meat processing facilities. The market dominance in wastewater treatment is due to the increasing demand for efficient and environmentally friendly ways to handle acidic wastewater that contains industrial metals.

However, the pharmaceutical segment is expected to grow at the fastest CAGR during the forecast period.The market for magnesium hydroxide in the pharmaceutical industry is expected to continue growing due to the ageing population and the increased prevalence of digestive issues. Because of its antacid and laxative qualities, magnesium hydroxide is mostly used in the pharmaceutical industry. Because of its osmotic properties and ability to neutralize stomach acid, it is a crucial component of many over-the-counter medications.
