Description of key information
Given the natural abundance of silicon dioxide and diatomaceous earth (which contains primarily silica), synthetic amorphous silica (SAS) is unlikely to affect birds in a harmful way. There is no data available to suggest that silicon dioxide is hazardous to birds. Furthermore, when chickens were fed a diet that contained less silicon dioxide than normal, their bone formation was harmed. Silicon is therefore considered an essential trace element for the chick (Carlisle E, Science 178(4061) 619 -621, 1972).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
