Silicon dioxide what are the dangers of ingesting these chemicals?

Answer 1

To my knowledge (I am a med student but that in no way gives me the authority to answer this with certainty) silica (silicon dioxide) is only dangerous via inhalation. Depending on the particulate size, particles may become lodged in the lungs causing lesions known as silicosis. I would assume that ingestion of SiO2 would not cause any damage except maybe for some vicious diarrhea or gastroenteritis. It is not soluble in water to any appreciable amount and even then, it is a relatively inert compound. Anyway, I don't think eating silica packets would be a fun past time but nevertheless don't do it.

Answer 2

Ingesting silicon dioxide, commonly found in food items as an anti-caking agent, is generally considered safe in small amounts. However, consuming large quantities can lead to irritation of the digestive system. Prolonged exposure to high levels of silicon dioxide may cause lung issues, such as silicosis, a serious respiratory condition.
