Cross Section and Composition of Halloysite Microtubules
Halloysite (Al2Si2O5(OH)4•2H2O) is chemically identical to kaolin clay, except the individual mineral crystals are curled into micron sized tubes. This gives Halloysite special properties. Diagram scale: 1Å (angstrom) equals one ten billionth of a meter, 1nm (nanometer) equals one billionth of a meter, 1µm (micron) equals one millionth of a meter.
Halloysite Clay CAS# 1332-58-7 - Halloysite is a special form of Kaolin and has the same CAS#.

The Environmental Protection Agency (EPA) has listed Halloysite as 4A which means minimal risk inert ingredients.
The Food and Drug Administration (FDA), has designated Halloysite as GRAS (Generally Recognized As Safe)
Halloysite is a non toxic natural material. Download the Material Safety Data Sheet in the link below. There is more safety data provided on the Precious Mineralz website.
