Potential Risk Index®:
1. Acidity Regulator / Buffering Agent - Changes or maintains the acidity or basicity of food/cosmetics.
2. Antiseptic / Disinfectant - Prevents growth of unwanted microorganisms.
Soda ash is the trade name for sodium carbonate , a chemical refined from the mineral trona or sodium-carbonate -bearing brines (both referred to as "natural soda ash") or manufactured from one of several chemical processes (referred to as "synthetic soda ash"). It is an essential raw material in glass, chemicals, detergents, and other important industrial products.
Sodium Carbonate is the disodium salt of carbonic acid with alkalinizing property. When dissolved in water, sodium carbonate forms carbonic acid and sodium hydroxide . As a strong base, sodium hydroxide neutralizes gastric acid thereby acting as an antacid.
