Magnesium Hydroxide Market To Reach $2,063.6 Million By 2030

Magnesium Hydroxide Market Growth & Trends

The global magnesium market size is anticipated to reach USD 2,063.6 million by 2030 and is projected to grow at a CAGR of 7.3% from 2025 to 2030, according to a new report by Grand View Research, Inc. The market is propelled by a robust set of production- and application-side drivers. Government-led industrial diversification policies and incentives further attract investments into large-scale, sustainable salt manufacturing projects. Technological innovation, including advanced membrane separation and automation, enhances purity, reduces environmental impact, and improves cost efficiency.

The industrial grade segment dominated the market, as it plays an important role in the chemical sector, particularly for the chlor-alkali process used in manufacturing chlorine and caustic soda. This demand was bolstered by the growth of petrochemical hubs in regions like the Middle East and Asia, where industrial diversification plans and low-cost energy made salt-based chemical production more viable. Additionally, industrial-grade salt saw consistent consumption from water treatment plants, textile processing, and metallurgical operations.

In water treatment, magnesium hydroxide serves as an alkalinity booster and sludge conditioner, neutralizing acidic streams in industrial effluents, this makes it a good option for long-term wastewater treatment projects. Additional benefits which make magnesium hydroxide more attractive to end users are its buffering ability which provides the added benefit of excellent pH control, and its handling properties. Unlike caustic soda, magnesium hydroxide is non-hazardous and non-corrosive when used properly which makes handling safer and easier.

The Asia-Pacific region leads the magnesium hydroxide industry, driven by the rise in demand in its uses as an antacid and laxative in over-the-counter medicines. With the expansion of global healthcare infrastructure and increasing consumer awareness of gastrointestinal health, the pharmaceutical demand for magnesium hydroxide is also rising.
