In skin care and personal care products like lotions and bath salts, sodium bicarbonate helps control a product’s acid-base balance to keep it from spoiling. In toothpaste, sodium bicarbonate helps to remove stains from teeth by dislodging tiny particles of food or beverages that can blemish tooth enamel. It is also a common ingredient in deodorant because it can help neutralize smelly, acidic scents.
Sodium bicarbonate also is an active ingredient in antacid products used to relieve heartburn and treat acid indigestion. It works by quickly neutralizing stomach acid and temporarily relieving symptoms of acid reflux.
