About Precipitated Sulfur Powder, Purified, 99.5%

Precipitated sulfur refers to a form of sulfur that is obtained through a chemical process called precipitation. Sulfur is extracted from raw materials such as natural gas, crude oil, or mined from sulfur deposits. The process involves reacting sulfur dioxide (SO2) with other chemicals, like hydrogen sulfide (H2S), to produce elemental sulfur.

Once obtained, this elemental sulfur is then converted into various forms, including precipitated sulfur. This form of sulfur is finely ground and often used in various industries, including pharmaceuticals, agriculture (as a pesticide or soil amendment), and the production of rubber, plastics, and chemicals.

Precipitated sulfur is known for its purity and fine particle size, making it suitable for a wide range of applications where precise control over sulfur content and particle size is required.

Common Uses and Applications

  • As a pesticide, fungicide, and soil conditioner
  • Vulcanization process of rubber
  • Topical medications for treating skin conditions

  • What is the difference between Precipitated Sulfur Powder 99.5% USP Grade and the purified version? How is it used differently in skincare?

    The key differences are:
    -USP grade precipitated sulfur powder meets or passes the specifications of United States Pharmacopeia for the product.  
      For topical uses in skin treatment USP grade is recommended.

    -Purified grade is a high purity >99.5% sulfur powder but the product is not further tested to determine specifications for other grades such as USP,NF, FCC or ACS. 
    High purity grade can be applied when the specific requirement is not USP. However it is customers responsibility to determine the compability of the product in their intended use. 

    Thank you.
