Lohtragon® Zinc Sulfates – Quality that Secures Your Processes
Our Zinc Sulfates are known for their high purity and reliability, making them trusted choices in demanding industrial applications.
With stable physical and chemical properties, they support processes in chemical synthesis, energy storage, and surface treatment, among others.
As a trusted German manufacturer, we ensure consistent quality and reliable supply to meet your most demanding requirements.
Zinc Sulfate is an inorganic salt with the formula ZnSO₄, and it often exists in hydrated forms such as the heptahydrate ZnSO₄·7H₂O (goslarite).
It consists of Zinc cations (Zn²⁺) and Sulfate anions (SO₄²⁻). In its pure, anhydrous form, it appears as a white or colorless crystalline solid;
hydrated forms are also colorless to white. The compound is odorless. Zinc Sulfate is soluble in water.
Select from our Zinc Sulfate range, manufactured at our German production sites. As the manufacturer, we offer direct access to a broad spectrum of product types and purities, from technical grade, food and pharmaceutical quality to special grades – just reach out to us for our established range or your individual requirements.

Interested in Zinc Sulfate for your application? Looking for a specific grade or regulatory support?
Our technical experts are here to help with:
Zinc Sulfates are salts of sulphuric acid and zinc, typically found in hydrated forms such as ZnSO₄·7H₂O (heptahydrate). The anhydrous form is a white or colorless crystalline solid; hydrated forms are also colorless. They are odorless and dissolve readily in water.
They are manufactured at our production facilities in Germany.
They are odorless under standard conditions.
Some grades may qualify for food-contact use, depending on regulatory conditions. We provide guidance and documentation for those applications.
If your required specification - hydration state, purity, zinc concentration, particle size, or form - is not listed, contact us. We will work with you to find or develop the appropriate grade.
