Product Overview
Anhydrous Magnesium Sulfate
At LOOK Chemical, we know your processes can’t afford surprises. That’s why our Anhydrous Magnesium Sulfate is engineered not just to meet the spec, but to safeguard your precision.
Produced under rigorously dry conditions, this 100% water-free powder delivers predictable, aggressive hygroscopicity. It’s the difference between simply removing moisture and doing it efficiently, batch after batch, protecting sensitive organic syntheses from side reactions. Beyond its role as a premier drying agent, its high-purity magnesium content makes it a trusted source for specialty agriculture and food-grade applications where consistency is non-negotiable.
Specification
The real value isn’t just in the bag. It’s in our understanding of what happens next. We package it under a nitrogen blanket and ship it in moisture-proof liners because we know its performance depends on arriving as dry as it left our facility. We think about your storage, your handling, and your final product integrity.
You’re not sourcing a commodity; you’re securing a cornerstone of your process stability. Let’s talk about how the right drying agent can remove more than water—it can remove uncertainty.

Hazard Information
GHS Classification
From a practical standpoint, our Anhydrous Magnesium Sulfate is a low-hazard material, but its physical form is what demands respect in the plant.
Hazard Info:
It’s non-flammable and non-toxic. The main risk is physical: the fine powder can create dust. In high concentrations, airborne dust may irritate the eyes, nose, and respiratory tract. It’s a nuisance, not a poison, but you don’t want to breathe it in.
Handling & storage
Handling:
This is where experience matters. Keep it dry. The moment it meets moisture, it starts to clump and lose its effectiveness as a desiccant. Use closed transfer systems where possible. For bag handling, wear basic PPE—safety glasses and a dust mask (N95 type) are sufficient to prevent irritation. Good general ventilation is key.
Storage:
The rule is simple: cool, dry, and sealed. Store bags on pallets in a dedicated, dry warehouse. A humid environment is its enemy, as it will slowly absorb water from the air (caking) and its quality will degrade. Keep the bags tightly closed after partial use. It’s compatible with most common materials, so no special containment is needed beyond keeping the area clean and dry.
In short: Treat it like flour in a professional kitchen—control the dust, keep it sealed, and it will perform reliably and safely for you.
FAQ
A: Good question. Watch for clumping. Fresh material is a free-flowing powder. As it absorbs water, it forms hard lumps or cakes. That’s your visual cue it’s saturated and needs to be regenerated or replaced.
A: Technically, yes. You can heat it in an oven at 200-250°C for several hours to drive off the water. But for most industrial applications, the energy cost and labor often make it more economical to use new material, unless you’re working with very large, dedicated systems.
A: Letting it breathe humid air. Even in a sealed bag, if you open it in a damp warehouse and don’t re-seal it tightly, it will start caking. Always seal the inner liner. A half-used bag stored poorly is a common source of quality complaints.
A: It’s all about the water. The hydrated forms (epsom salt) already contain crystal water and are useless as drying agents. Our anhydrous grade is 100% water-free, making it a powerful desiccant. Using the hydrated form for drying is like using a wet sponge to dry a plate – it doesn’t work.
A: For critical applications, a quick lab test is to add a small amount to a solvent like acetone that contains a known trace of water. You can use a Karl Fischer titrator to measure the water content before and after. A significant drop confirms activity.
A: Generally, no. It’s compatible with mild steel, stainless steel, and common plastics like polyethylene (used in our bag liners). The main concern is ensuring the equipment itself is dry during charging.
A: Typically not in a problematic way. It’s chemically stable and non-reactive with most common fertilizer salts like nitrates or phosphates. However, always test a small batch first. Its main job is to supply magnesium without introducing moisture.
A: For standard 25kg bags, we usually ship from stock within 5-7 working days. For larger, consistent volumes (e.g., full container loads), we absolutely work with clients on scheduled, just-in-time deliveries. Let’s discuss your forecast.
A: We track two key physical specs closely: Particle Size Distribution (affects surface area and drying speed) and Loss on Drying (LOD) to guarantee it’s truly “anhydrous”. We can provide these certs on request.
A: You’ll get direct access to our technical team – people like me who’ve seen it in use. We can troubleshoot over email, phone, or share best practice documents. For complex new applications, we can even arrange a small sample for your own trials first.
