Eco-SilTM is amorphous biogenic silica with high purity and surface area, harvested from rice hulls.

It is an ecofriendly alternative to fumed

(pyrogenic) silica, manufactured in the

U.S. It has been “Generally Recognized as

Safe” (GRAS) by the FDA; it contains no

heavy metals. It has 3X the bulk density of

fumed silica, resulting in decreased shipping

costs, easier handling on the manufacturing

floor and lower dusting.
