Synthetic substance - maybe

E500 (i) - Sodium carbonate: Sodium carbonate is naturally occurring in alkaline waters, however it is also synthesised by the Solvay process or by electrolysis of sea water. Sodium carbonate is used as an acidity regulator, particularly in beer making. Excessive ingestion may result in stomach upset. Typical products include beer, baking, soft and fizzy drinks, medications. No known adverse effects in small quantities. May irritate the eyes and respiratory tract.
