Sodium bicarbonate is a chemical compound with the formula of NaHCO3, also known as sodium hydrogen carbonate, baking soda, bicarbonate of soda, sodium bicarbonate, sodium acid carbonate. CAS No. 144-55-8. EC No.205-633-8. E500(ii). It is an odorless, white and crystalline powder with a slightly alkaline (bitter) taste and PH value between 8.0 and 8.6 (1 % solution). It is soluble in water and insoluble in ethanol. Sodium Bicarbonate is the monosodium salt of carbonic acid with alkalinizing and electrolyte replacement properties.
Sodium bicarbonate is widely used in daily life, such as cooking, pest control, paint and corrosion removal, alkalinity/PH increase, pyrotechnics, mild disinfectant, fire extinguisher, neutralization of acids and bases, medical, personal hygiene, cleaning agent, feed supplements and so on. About 26% of sodium bicarbonate is used in household products; 21% in animal feed; 16% in food, baking & beverage ; 14% in plastics & chemicals ; 9% in exports; 6% in pharmaceuticals & personal care products; 2% in fire extinguishers; 2% in soaps & detergents; 2% in air pollution control and 2% in miscellaneous.
Sodium bicarbonate injection uses Sodium bicarbonate, as an active pharmaceutical ingredient, can be used to treat high acid levels in the blood, lower acid levels in the urine, and replace bicarbonate loss caused by very bad loose stools(diarrhea).

Sodium bicarbonate uses in food and drink Sodium bicarbonate is affirmed by US FDA as GRAS(generally recognized as safe) and widely accepted as a safe food additive in many countries with E number E500. NaHCO3is the reaction of strong base and weak acid, showing weak alkaline in water. It is commonly used as acidity regulator, leavening agent, and raising agent. Heating above 80 ℃can cause sodium bicarbonate to act as a raising agent in baking because of thermal decomposition, releasing CO2. Therefore Sodium bicarbonate can be used in pancakes, cakes, quick breads, soda bread, and other baked and fried foods as leavening agents. It also can be used in beverage and sports drink as PH regulator or leavening agents. But there will be a taste of alkali if use too much because some sodium carbonate will be left after thermal decomposition.

Sodium bicarbonate uses in cosmetics Sodium Bicarbonate is used in the formulation of bath, skin, and hair preparations in cosmetics and personal care products. It is used to control the acid-base balance of cosmetic products. In cosmetics and personal care products, Sodium Bicarbonate may also be used as an abrasive, a deodorant agent, and an oral care agent.
If you want to avoid the parabens and aluminum found in many deodorants and antiperspirants, try a pinch of baking soda (sodium bicarbonate) mixed with water instead. This simple paste makes an effective and simple natural deodorant.
Sodium bicarbonate uses for skin Applying a paste made of baking soda and water to insect bites can help relieve itching. This is also effective for itchy rashes and poison ivy. Baking soda helps to relieve minor skin irritation and itching by neutralizing toxins and irritants on your skin's surface.
Sodium bicarbonate can also be used as a facial cleanser to remove dead skin cells, oil or dirt from the skin. It works by physically removing the top layer through the abrasive action of the particles within the baking soda mix. What makes it especially effective is that it is a fine, yet hard powder, making it highly effective at removing the dead skin cells without causing excessive irritation. But commonly reported its side effects for those with sensitive skin include tingling, itchiness, smarting or generally painful skin. Some people report that their skin feels dryer when using baking soda or more prone to irritation.
Add 1/2 cup of baking soda to lukewarm bathwater, then soak in the tub for natural relief. When you get out, let your skin air dry, rather than toweling off the excess baking soda, for extra relief. You can also add a mixture of baking soda and water to a cool compress and apply it to the sunburn directly.
Sodium bicarbonate uses in cleaning Mix three parts baking soda with one part of water to make a natural hand cleanser that will scrub away dirt and neutralize odors. Baking soda has a mild abrasive action that helps to remove plaque and polish, clean, and deodorize your teeth. Sprinkle baking soda on a vegetable brush to help remove dirt and residue from fruits and veggies. It is also used in a process for removing paint and corrosion. A paste made from baking soda with minimal water is recommended by a manufacturer as a gentle scouring powder, and is useful in removing surface rust, as the rust forms a water-soluble compound when in a concentrated alkaline solution; cold water should be used, as hot water solutions can corrode steel.
Sodium bicarbonate uses In other uses Sodium Bicarbonate can be used as feed additive in agriculture/animal feed/poultry feed, such as cattle feed supplement.
As heating of sodium bicarbonate releases carbon dioxide, sodium bicarbonate can be used to extinguish small grease or electrical fires by being thrown over the fire. But it should not be applied to fires in deep fryers; the sudden release of gas may cause the grease to splatter.
There are three grades of sodium bicarbonate: medicinal grade, food grade and industrial grade. The purity of industrial grade is much lower than others. The global demand of sodium bicarbonate is more than 80million tons/year. China is main manufacturing and export country. Chinese suppliers are Boyuan, Yuhua, Haitian, etc. For more suppliers or prices, please visit okchem.com.
