Silica is safe

Silica is the common name for silicon dioxide (SiO₂). SiO₂ is very common in nature, for example, as crystalline silica in quartz or grains of sand. Another form of silica, amorphous silica, is found in human and animal organisms as well as in plants. The two components in this compound, oxygen and silicon (approx. 27%), are among the most common elements in the Earth's crust when measured by weight.

The industry can produce silicon dioxide synthetically through different processes. The inhomogeneous natural raw material is converted into silica products with a constantly high purity and quality for a wide spectrum of specific applications in numerous industries. In simple terms, sand is turned into a valuable high-purity material. Only in this pure form is synthetic amorphous silica an essential additive for countless industrial applications.

Evonik produces only synthetic amorphous silica, or SAS.

The synthetic amorphous silica (SAS) types produced by Evonik are safe for everyone
involved in production, processing, transportation, and storage, as well as for consumers
of the end products. Evonik (including its predecessor companies) has been producing SAS since the 1940s. It is one of the most rigorously tested substances regarding potential risks to humans or the environment.
