We have a number of high quality grades including reagents, drug agents, cosmetics, food additives, feed additives, etc.,including special grades guaranteeing Japan's highest purity of 99.99% by original technology of UMAI Chemical. We will deliver high quality magnesium sulfate to customers who need them, all over the world.

Number One Share in Japan/Purified Magnesium Sulfate

Our purified magnesium sulfate, which achieved number one in Japan for both production volume and sales share, is active in various fields such as industrial raw materials, water soluble fertilizer, and improving performances of high-tech products.

Characteristic of Magnesium Sulfate
1. Excellent solubility in water
2. It is an agent which is chemically stable, safe, harmless and environmentally friendly
3. It is an agent which is less corrosive to metals

As top manufacturer of magnesium sulfate, we respond to wide range of requests. As types of dried magnesium sulfate, we offer crystal waters in anhydride, 1.5 hydrate, 2.5 hydrate, 3 hydrate, as well as in various particle size from sulfur to granule, reagents, food additives, feed additives, fertilizer, industrial use, etc.
Also, from 2018, we commercialized USN-00, which is an extremely fine anhydrous magnesium sulfate with an average particle size of about 3 μm. It is expected to be applied to various applications as a functional material, such as warming agents and hygroscopic agents.

11Characteristics of Dried Magnesium Sulfate
1. Diameter of each particle is from ultrafine to granule
2. Four different grades of crystal water
3. High clarity of aqueous solution
4. Dissolves well in water
5. Low corrosiveness
6 .Stable up to approximately 700 degrees Celsius
7. Hygroscopic function (degree of water absorption capacity for anhydrous salt is almost the same as its own weight) used as desiccant
8. Generates heat when melting, used as warming agent
9. Applied for carrier and filler
10. Difficult to harden due to its smooth behavior
11.Safe, harmless and environmentally friendly
