Eco-Sil Specifications

Eco-sil™ capsulesEco-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.

Other characteristics include:

Submicron particle size

Hydrophilic surface
