Sio-Tex is a silica manufacturer of an alternative for fumed silica called Eco-Sil™. The patent pending technology uses rice hulls, an abundant biowaste, as the raw material. The technology won an EPA award for its ability to reduce rice hull landfilling and field burning.Eco-Sil is amorphous biogenic silica with high purity and surface area that is an ecofriendly alternative to fumed (pyrogenic) silica and is manufactured in America. Eco-Sil is also Generally Recognized as Safe (GRAS) by the FDA and contains no heavy metals.Eco-Sil can be used for thickening, shear thinning (thixotropic), and anti-settling behavior in liquid systems. It is efficient in non-polar to medium polarity systems and offers a balance of thickening efficiency and dispersibility.
