Silica is safe to use

Regular critical reviews of existing literature based on strong scientific data confirm the safety of SAS.

Epidemiological studies in five Evonik production sites in Germany over recent decades do not show any risk potential either.

Evonik actively participates in projects to include new developments of toxicological methods, avoiding animal testing.

Evonik Silica is an amorphous material. In contrast to crystalline silica, Synthetic Amorphous Silica (SAS) does not cause silicosis.

Synthetic Amorphous Silica (SAS) is approved as a food additive in the EU (identification number E 551). This approval ensures the additive is safe and can be used without concern.

Although SAS is used only in very small quantities in food, it is safe to consume even in larger amounts.

SAS is regularly re-evaluated by the European Food Safety Authority EFSA. Most recently, in its scientific opinion in January 2018, the EFSA again clearly stated that there is no safety risk from the current use of SAS in food, and no indication for toxicity was found.
