Can Precipitated Sulfur Powder, Purified, 99.5% be used for mercury spill in my home for clean up or is it toxic as well?
Hi,
Yes. It can be used for clean-up. Any powdered sulfur will work for your application.
Thanks,

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.
