Magnesium sulfate monohydrate
Product Parameters
Basic Properties
- Appearance & Odor: White, odorless crystalline powder or free-flowing granular solid; slightly hygroscopic (weaker than anhydrous magnesium sulfate), non-efflorescent, non-corrosive
- Melting Point: 200 °C (392 °F); loses crystal water when heated to 200-300 °C, decomposes at temperatures above 1124 °C
- Density: 2.45 g/cm³ (25 °C, lit.); bulk density: 1100-1300 kg/m³
- Solubility: Highly soluble in water (30.5 g/100 mL at 20 °C; 54.6 g/100 mL at 60 °C), soluble in glycerol and ethanol, slightly soluble in ether, insoluble in acetone
- pH Value: 5.5-7.5 (25 °C, 50 mg/mL in water)
2. Chemical Properties (Stability & Reactivity)
- Stability: Chemically stable under normal temperature and pressure; slightly hygroscopic, absorbing a small amount of moisture from air (weaker than anhydrous magnesium sulfate); incompatible with strong oxidizing agents, alkaline substances, and ethoxyacetylene alcohols (may cause explosion when heated together); avoid long-term exposure to humid air to prevent caking
Main Applications
1. Agriculture & Horticulture – High-Efficiency Nutrient Supplement
As a premium dual-nutrient supplement (Mg & S), it is widely used in open-field agriculture, greenhouses and hydroponics to correct soil magnesium and sulfur deficiencies. With high water solubility (37.1% at 25℃), it quickly provides magnesium (a core component of chlorophyll) to enhance photosynthesis, and sulfur (essential for amino acid synthesis), promoting crop growth, yield and quality. Suitable for various crops (e.g., potatoes, tomatoes, fruits, grains) and all soil types, it can be used as base fertilizer, topdressing or foliar spray, with high nutrient utilization and no soil compaction.
2. Pharmaceutical & Healthcare – Safe Excipient & Nutrient Carrier
In pharmaceuticals, it serves as a safe excipient, osmotic laxative (mild efficacy) and water-soluble carrier for poorly soluble drugs, with better biocompatibility and chemical stability (neutral pH 5-8). It is also used in magnesium supplements to meet human magnesium intake needs and as a microbial fermentation carrier to promote microbial growth. Compliant with international pharmaceutical standards, it is widely applied in drug formulations and health products.
3. Chemical Industry & Intermediates
As a key green intermediate and Lewis catalyst, it is used in the production of magnesium salts (e.g., magnesium hydroxide, magnesium oxide) and as a catalyst in organic synthesis (e.g., synthesis of benzopyranones). It also acts as an electrolyte for copper sulfate preparation and supports large-scale industrial production, complying with relevant industrial standards.
4. Food & Feed Industry – Safe Additive
In the food industry, it is a food additive (acid regulator, stabilizer, coagulant) used in baked goods, dairy products, beverages and tofu making, complying with international safety standards (e.g., FDA, EU). In the feed industry, it supplements essential magnesium and sulfur for livestock, supporting bone development and enzyme activation, suitable for various feed formulations.
5. Industrial Applications (Textile, Leather & More)
In textiles, it acts as a dyeing auxiliary and weighting agent to improve dye fixation rate, color fastness and fabric quality. In leather tanning, it serves as a filler to enhance heat resistance. It is also used in electroplating (electrolyte additive to refine plating layers), papermaking, soap and detergent production, optimizing process efficiency and product performance.
6. Cosmetics & Other Emerging Applications
In cosmetics, it is a skin-friendly component added to formulations for its mild and compatible properties. It also serves as a precursor for synthesizing magnetic nanoparticles and energy storage materials, supporting the development of new energy and nanomaterial fields.
Safety Precautions
1. Safety & Handling Instructions
- Use in well-ventilated areas to avoid dust inhalation (magnesium sulfate monohydrate is slightly hygroscopic, minimizing dust dispersion).
- Avoid eye/skin contact; do not ingest or breathe dust (dust may cause mild to moderate irritation).
- Wash hands thoroughly after handling; prohibit eating, drinking, or smoking in work zones to prevent accidental ingestion.
- Handle containers gently to prevent spillage; minimize dust creation and avoid contact with moisture to prevent clumping.
2. Personal Protective Equipment (PPE)
- Eye/Face: Chemical safety goggles or face shield (prevents eye irritation from dust particles).
- Hands: Chemical-resistant gloves (nitrile or latex) to avoid skin contact and minor irritation.
- Body: Impervious lab coat or protective clothing to prevent fabric contamination and clumping from moisture.
- Respiratory: NIOSH-approved dust mask (required when handling large quantities or during spill cleanup).
